Background & objectives: Enterococcus spp. are predominant in the faecal microflora which enter the environment directly or through wastewater. These bacteria play an important role in the development of nosocomial infections due to their ability to acquire resistance genes and their transmission to other bacteria, particularly Staphylococcus aureus. The aim of this study was to identify the prevalence of vancomycin-resistant enterococci (VRE) and to detect van A, van B and van C1/C2 genes in VRE strain isolated from environmental samples of the in southern Fars province. Methods: This cross-sectional study was carried out on 155 Enterococcus spp isolates collected from environmental samples (hospital wastewaters and surface waters) in different areas of Larestan and Jahrom cities. Isolates were identified and confirmed as Enterococcus spp. using the membrane filtration method, selective growth on Kenner Fecal Streptococcus Agar (KF) medium and biochemical tests. The disk diffusion test and Macro Broth dilution method based on CLSI guidelines were used to determine antimicrobial susceptibility against conventional antibiotics and vancomycin and to measure the minimum inhibitory concentration (MIC), respectively. Finally, the presence of van A, van B and van C1/C2 genes in VRE strains was determined by multiplex PCR technique. Results: Out of all of Enterococcus spp. isolates, 41 cases (26.45%) were belonged to E.faecalis, 6 cases (3.87%) to E.faecium and 108 cases (69.68%) to non-faecalis and non-faecium. In total, 46 isolates (29.67%) were resistant to vancomycin and 4 isolates showed MIC =128 µg/ml. Resistant to all types of antibiotics was observed in 4 isolates (8.70%). Further, 2 isolates (50%) had vanA gene and 2 isolates (50%) had vanB gene, but vanC1/C2 genes were detected in none of them. Conclusion: The results indicated that the VRE strains are widespread in the studied area, therefore there is an urgent need for prudent use of vancomycin and implementation of control measures to prevent the environmental spread of VRE strains.

Background & objectives: exposure to lead has a wide range side effects on fertility. Vitamin D is one of the most important vitamins required for the body. This study was conducted to determine the effect of vitamin D on spermatogenesis in male rats treated with lead nitrate. Methods: In this experimental study, 25 adult male Wistar rats (250-300 gr) were randomly divided into 5 groups (n=5). Control group without any treatment, the group receiving lead by gavage and experimental groups receiving lead plus vitamin D at doses of 25, 50 and 75 mg/kg body weight by gavage for 28 days. At the end of the study, after anesthetizing the rats, blood samples were collected directly from heart and serum levels of testosterone hormone, Follicle-stimulating Hormone (FSH) andLuteinizing Hormone (LH) were measured. Histological studies were performed to count the spermatocyte and examine the diameter of the seminal tube. Data were analyzed by SPSS software using one-way ANOVA, at significance level of p>0.05. Results: Compared to the control group, the mean serum testosterone level in the lead group significantly decreased (p<0.001) and the mean LH and FSH serum levels significantly increased (p<0.001) . Also, spermatocytes and seminiferous tubule diameter significantly decreased (p<0.001). Vitamin D consumption reduced the effects of lead intake, and this effectiveness was completely dose-dependent. Conclusion: Our data showed that vitamin D has a significant effect on serum testosterone levels and gonadotropins.

Background & objectives: The present study examined the gonadotoxic effects of ciprofloxacin antibiotics and protective effects of L-carnitine. Methods: In this study, 20 NMRI mice were divided into four groups: control, ciprofloxacin, L-carnitine, L-carnitine-ciprofloxacin (each group included 5 animals). The control group received normal saline, the treatment group 1 received 12.5 mg/kg ciprofloxacin, the treatment group 2 received 100 mg/kg L- carnitine and the treatment group 3 received 100 mg/kg L- carnitine and 12.5 mg / kg ciprofloxacin simultaneously. All animals were treated by intraperitoneal administration for 15 days. Testis and epididymis were collected to evaluate sperm parameters (sperm count, motility, morphology and viability). Results: In the ciprofloxacin group, a significant decrease in sperm count, sperm viability, sperm motility, progressive sperm motility and normal sperm as well as a significant increase in rotating sperm motility, sperm without movement, head and tail abnormalities were observed (p=0.05). A significant increase in sperm count, sperm survival, motility and progressive sperm motility, normal sperm and a significant decrease in rotating sperm motility, sperm without movement and head abnormalities in the L-carnitine-ciprofloxacin group were observed (p=0.05); however, the reduction in tail abnormalities of sperm was not significant. Conclusion: L-carnitine improves sperm parameters in the adult mice treated with ciprofloxacin.

Background & objectives: Micro-RNAs are non-coding RNAs with a length of approximately 22 nucleotides, which, by binding to the target genes mRNA, regulate its expression and play an important role in tumor suppression. Changes in the expression level of microRNAs play a crucial role in the pathobiology of multiple cancers. In this study, the expression levels of miR-143 and miR-338 were compared in gastric cancer and its margin. Methods: This case-control study was performed on 35 biopsy samples of gastric cancer and adjacent tissue of the patients who were admitted to Imam Reza Hospital. Total RNA was extracted from the tissue using Trizol reagent and based on the companys instructions. Then, the acquired microRNAs were used to synthetize cDNA. Expression of microRNAs was measured by RT-PCR. U6 was used as a house keeping gene. Statistically, the obtained results were analyzed using Graph pad Prism software. Results: According to the results obtained in this study, the expression levels of miR-143 (p=0.1244) and miR-338 (p=0.0059) in tumor tissue, compared to the adjacent tissue, were down-regulated. Reduced expression of miR-143 and miR-338 in the tumor tissue, in comparison to margin tissue, was about four folds. Conclusion: This study showed that the average expression level of miR-143 and miR-338 was significantly decreased in gastric cancer tissues compared to adjacent non-tumor tissues, and these results strongly suggest that miR-143 and miR-338 may play a key role in gastric cancer progression; therefore, they may be considered tumor markers.

Background & objectives: Therapeutic abortion in the second trimester of pregnancy can be done by a number of medical or mechanical methods. The aim of this study was to compare the efficacy of vaginal misoprostol with and without letrozole and combination of misoprostol and laminaria in preoperative cervical ripening among women with under second-trimester abortion. Methods: In this interventional study, 120 pregnant women with the gestational age of 20 weeks, who were candidates for therapeutic abortion, were selected and randomly divided into three groups (n=40). Proper counseling was done and a written informed consent was obtained before starting the treatment regimen. The first group received vaginal misoprostol alone and the second group received misoprostol in combination with laminaria and oral placebo. In the third group, in addition to cervical placebo on the first and second days, letrozole was prescribed, and on the third day, the patients were hospitalized and received vaginal misoprostol and third dose of letrozole. The patients were regularly examined every 4 hours, and in the absence of abortion, vaginal misoprostol was repeated after 4 hours. Results: The results showed that termination of pregnancy was caused by embryo anomaly in 23 cases and fetal death in 97 cases. In this study, response to treatment was 90% in the group receiving laminaria and misoprostol 85% in the group receiving letrozole and misoprostol and 67% in the group receiving misoprostol. Regarding the duration and amount of bleeding, the groups receiving laminaria and misoprostol had the lowest duration and severity of bleeding, but this difference was not statistically significant. Combination of misoprostol and laminaria caused a significantly shorter time interval from the initiation of intervention to abortion, and pain relief was also higher than the other two groups. Conclusion: Based on the obtained results, a combination of misoprostol and laminaria is recommended for induction of second-trimester therapeutic abortion.

Background & objectives: Considering the prevalence of diabetes and importance of its prevention, control and treatment, using low-calorie natural sweetener is necessary. Hepatoprotective and antidiabetic properties of the aqueous extract of Stevia. rebaudiana were assessed in the present study. Methods: In this study, 35 mature male mice were divided into 5 groups. Diabetes was induced by administration of 60 mg/kg of streptozotocin intraperitoneally. The negative control group received normal saline and treatment groups received glibenclamide with 0.5 mg/kg and 200 and 400 µg/kg of aqueous extract of S. rebaudiana through gavage for 15 days, respectively. Also, one group was considered as positive control (as non-treated diabetic). On the last day, the blood glucose levels of samples were measured. After periodic acid Schiff (PAS) staining, 5µm of sections were used for stereological analysis. Results: The blood glucose level was decreased (p<0.05) significantly in aqueous extract-treated groups compared to the untreated diabetic mice. The weight and volume of kidneys, cortex, medulla, proximal and distal tubules, collecting ducts, loop of henle, interstitial tissues, vessels and length of renal tubules decreased significantly (p<0.05) after treatment with aqueous extract of S. rebaudiana (p<0.05). The number and volume of glomeruli restored toward normal levels with high doses of S. rebaudiana. Conclusion: According to the obtained results, aqueous extract of S. rebaudiana (sweet fraction) can regulate the blood glucose levels and inhibit diabetes-induced renal damages. It seems that S. rebaudiana can be used as an antidiabetic and nephroprotective supplement.

Background & objectives: Appropriate nutritional behavior is effective in controlling many diseases such as cardiovascular diseases. This study aimed to determine the effectiveness of nutrition counseling in improving nutritional behavior, lifestyle and healthy nutrition in patients with myocardial infarction. Methods: In this interventional study, 120 patients admitted to the cardiac care units of the hospital, were selected by convenience sampling method and randomly assigned into two groups. Data were collected using MEDFICTS and demographic questionnaires. After running the questionnaire, interventional group (n=60) with a score of more than 70 received nutritional counseling. After the end of nutritional counseling (3 sessions, 90 minutes), the subjects were re-evaluated for nutritional behavior. Data were analyzed using t-test in SPSS20 software. Results: The mean age of the participants was 62.73±11.56 years, and 53.7% of them were female. The mean MEDFICTS scores before the consultation in the interventional group and control group were 43.2±14.8 and 43.5±18.2, respectively. The difference between the two groups was not statistically significant (p=0.3). The mean MEDFICTS scores at the end of the study in interventional and control groups were 13.14±62.6 and 23.3±2.24, respectively. This difference was significant between groups (p<0.001). Conclusion: MEDFICTS scores improved in patients with myocardial infarction receiving nutritional counseling. It seems that the operation of nutritional counseling in patients with myocardial infarction can be effective in reducing the incidence of this disease

Background & objectives: Andrographolide has potent antioxidant properties. There is still not a complete understanding of the antioxidant effects of andrographolide. In this study, the effect of andrographolide on the serum antioxidant activity of superoxide dismutase and catalase was investigated in the rats with secondary iron overload. Methods: In this experimental study, 32 rats were divided into 4 groups of 8 each. The groups included: 1-Control 2- Receiving iron 3- Receiving iron treated with 7 mg/kg andrographolide 4- Receiving 7 mg/kg andrographolide. The serum activity of superoxide dismutase and catalase and serum level of malondialdehyde (MDA) was measured using colorimetric method. Prussian blue was used to evaluate iron deposition in liver. Results: The results showed that iron was deposited in the liver. The activity of superoxide dismutase and catalase in the secondary iron receiving group, compared to control group, was significantly increased (p<0.05). The activity of catalase was significantly decreased in the group receiving iron and treated with andrographolide, compared to the control and iron receiving groups (p<0.05). Also, the activity of superoxide dismutase in the group receiving iron and treated with andrographolide decreased significantly compared to the iron receiving group (p<0.05). Serum levels of malondialdehyde in the iron receiving group were higher than the control group (p<0.05). Serum levels of malondialdehyde in the group receiving iron and treated with andrographolide, compared with the iron receiving group, showed a significant decrease (p<0.05). Conclusion: Andrographolide (7mg/kg) reduced the serum activity of catalase and superoxide dismutase and malondialdehyde serum levels in rats with secondary iron overload.

Background & objectives: Cancer is one of the leading causes of morbidity and mortality worldwide. Leukemia is a cancer of blood cells and bone marrow, which is characterized by abnormal growth of white blood cells, known as blasts. Chronic myeloid leukemia is a clonal hematopoietic stem cell disorder that accounts for 15-20 percent of adult leukemia. Embelin, a natural compound found in the fruit of Embeliaribes plant, has low toxicity and potent anticancer properties. Several studies have shown that the anticancer properties of Embelin are due to inhibition of XIAP (X-linked inhibitor of the apoptosis protein) and modulation of NF-kB signaling pathway. The aim of this study was to investigate the effect of Embelin on the growth and apoptosis of K562 cell line. Methods: K562 cells were cultured in RPMI-1640 medium containing 10 % FBS and 1% penicillin. Then, the cells were treated with different concentrations of Embelin (2, 4, 6, 8 µM/ml) for 72 hours. MTT assay was used to determine the viability of cells. Hoechst staining and DNA electrophoresis were used for apoptosis analysis. Result: Based on the results of MTT assay, Embelin inhibited the viability of K562 cells. The results of Hoechst staining showed that DNA fragmentation was increased in the treated cells. DNA electrophoresis analysis revealed that Embelin induced apoptosis. Discussion: As the results showed, Embelin inhibited the cell growth and induced apoptosis in K562 cells time- and dose-dependently. Therefore, Embelin may be a candidate for treatment of chronic myeloid leukemia.

Background & objectives: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in the world which is associated with cardiovascular disease. The aim of this study was to investigate the plasma changes of chemerin and pentraxin-3 (PTX3) following 8 weeks of endurance training in men with NAFLD. Methods: In this quasi-experimental Study, thirty four patients with NAFLD were selected purposefully. The participants were randomly divided into two groups, endurance training group (n=17) and control group (n=17). The endurance training program included eight weeks running on a treadmill with maximum heart rate (HRmax) intensity of 55-75% for 45 minutes three times a week. Seventy two hours before the beginning of the study and at the end of the eighth week, blood samples were taken from all the participants. The data were analyzed by paired sample t-test and independent t-test at the significant level p<0.05. Results: Plasma levels of chemerin in the endurance training group significantly decreased (p=0.013). Also, there was a significant difference between the two groups after the end of the intervention (p=0.002). Plasma levels of PTX3 increased significantly in the endurance training group (p=0.001). There was also a significant difference between two groups after the end of the intervention (p=0.01). Conclusion: The present study showed that the 8-week endurance training increased the plasma levels of PTX3 and decreased the plasma levels of chemerin in men with NAFLD. Endurance training, possibly through various mechanisms, reduces the inflammatory factors and increases the anti-inflammatory factors in men with NAFLD. Endurance training, probably by activation of lipolysis, over-regulation of unpaired protein-1 and activator receptors of peroxisomes proliferation-, changes in adipocytokines, etc. decreases charmicin and increases PTX3 levels of plasma in men with NAFLD.

Background & objectives: Prostate cancer is one of the most common cancers in the world, and its prevention is expected to increase in the future appreciably. Following the emergence of the new field of nutritional genetics and investigations about the effect of natural antioxidants on the hypermethylation of genes, this study was performed to measure the effect of Vaccinium arctostaphylos poly phenols and anthocyanins on PC-3 cell line as well as methylation and expression changes of GSTP1 gene. Methods: In order to evaluate the survival potency of PC-3 cell line in a completely randomized design, MTT test was used and these cells were treated with different concentrations of Vaccinium arctostaphylos extract (4500, 2250, 1125, 562.5, 140.62, 70.31, 35.15, 17.57, 8.78, 4.39 µg/ml) for 24, 48 and 72 hours. Expression level of GSTP1 gene was analyzed by Q-RT-PCR method in 2500, 1250, 625, 312 and 156 µg/ml concentrations of Vaccinium. Results: Statistical results showed that Vaccinium arctostaphylos poly phenolic extract at 35-70 ppm concentration significantly reduced the survival rate of PC-3 cells. Moreover, compared to control cells, the expression level of GST gene significantly increased in PC-3 cells treated with 1250ppm extract. Conclusion: Anthocyanin- polyphenolic extract from Vaccinium arctostaphylos can decrease the survival rate of cancerous cells and GST gene expression in human prostate cancer PC-3 cells. This may be explained by changes in cell carcinogenesis pathway or CpG demethylation process. Keywords: Vaccinium arctostaphylos; Antioxidant; Cancerous Cells; Prostate.

Background & objectives: The purpose of this study was to investigate the effect of endurance swimming exercise training on structural remodeling (volume and parenchymal cell number) and apoptotic index of adrenal gland in pregnant rats exposed to cadmium poisoning. Methods: A total of 32 pregnant rats weighing 200 ± 20 g were randomly divided into four groups of control, cadmium, swimming, and cadmium-swimming. Cadmium dissolved in drinking water was administered to treatment groups, available ad libitum during pregnancy. Swimming exercises 5 days/week and 60 min/day were performed from the first day of gestation until the end of the period. Two days after delivery, the mothers were sacrificed and their adrenal glands were removed. After stabilizing the samples, Hematoxylin-Eosin staining and TUNEL assay were performed, and the number of necrotic and apoptotic cells in 10 microscopic fields was counted randomly. The size of various regions of the adrenal gland and total number of parenchymal cells were estimated using stereological methods. Data were analyzed by two-way ANOVA under SPSS software (version 21). Results: Cadmium poisoning caused extensive bleeding and tissue destruction in the adrenal gland of the pregnant mothers, but endurance training reduced the amount of bleeding. Cadmium poisoning during pregnancy decreased the total volume of the gland, the volume of the cortical part and its different layers as well as the number, size and function of parenchymal cells in all three cortical zones, especially the fasciculata zone. Performing swimming exercise training in this condition worsened the structural state of the gland and led to a further reduction in the number of parenchymal cells within all three parts of the adrenal gland. Conclusion: Exercise training in determined intensity increased the structural and morphological complications of cadmium toxicity in the adrenal gland of pregnant rats. So, pregnant mothers are advised to use low-intensity exercises and trainings.

Background & objectives: Prostate cancer is one the most common cancer in men whose incidence is increasing in many countries. According to the studies, decreased expression of miR-143 has been reported in prostate cancer. In this study, we replaced miRNA-143 in prostate cancer cells by vector based miRNA-143 and evaluated its inhibitory effects on migration of prostate cancer cells (PC3). Methods: MTT assay was performed to reach an inhibitory concentration of Genticin antibiotic (G418 (in PC3 cells. Then, miRNA-143 vector was transfected into PC3 cells via JetPEI transfection reagent. The transfected cells were selected by G418 antibiotic according to a 2-week treatment with IC50 concentration. Then, the expression level of miRNA-143 was measured by qRT-PCR method. To evaluate the effect of miRNA-143 in inhibition of migration, scratch wound healing assay was performed. Results: Results of MTT assay showed the IC50 level of G418 on PC3 cells was obtained to be 141.9 µg / ml. The results of qRT-PCR indicated increased expression of miRNA-143 in PC3 cells transfected with miRNA-143 compared to control cells. Finally, the results of wound healing assay showed migration reduction in transfected cells compared with control cells (empty vector). Conclusion: The results showed that miRNA-143 play an important role in cell migration during prostate cancer metastasis, and it can be a good candidate for molecular treatments.

Background & Objectives: Breast cancer is one of the most common cancers of women in the world. Apoptotic pathway is one of the most important pathways to deal with cell damage, especially cancer, which is usually blocked in this disease. One of the main enzymes to set up this pathway is JNK (1,2,3a,3ß), which is activated by cellular stress. Methods: In this study, breast cancer cells with the origin of MCF-7 cell lines were cultured in RPMI medium using 10%fetal bovine serum.Then , they were subjected to heat (42 & 45 ° C) for 1,2,4,6 and 8 hours under X-ray and ?-ray radiations for 1,2,3 and 4 hours as well. Their viability and enzyme level were evaluated by MTT and ELISA tests, respectively. Results: The obtained results showed that abiotic stresses including heat and radiations resulted in JNK level increase and recovery of apoptosis pathway function in breast cancer cells. In addition, they led to decreased of cell viability and increase of JNK level depending on the duration and kind of stress. Conclusion: The results in this study showed abiotic stress directly affected the JNK level. Increase of this enzyme in the cell resulted in activity of JNK apoptosis pathway. We hope to find methods to help to cancer treatment by means of more studies on JNK enzyme and relevant pathways.

Background & objectives: Coronary artery disease (CAD) is the most common cause of mortality and disability around the world. Determination of the health status and spatial and temporal patterns of the disease prevalence has a major role in health planning. This study aimed to investigate the spatiotemporal pattern of CAD in Ardabil Province. Methods: This descriptive and cross-sectional study was performed using the data belonging to 60156 patients with history of hospital admission due to CAD in Ardabil Province during 2010-2015. Hospitalization Rate (HR) was calculated after classification of the data in terms of location and date of hospitalization. The spatiotemporal and demographic variables, including age, gender, type of CAD, periods and duration of hospitalization were analyzed by descriptive statistics, ANOVA and repeated measures in SPSS v23 statistical software. Spatial distribution maps were drawn for each month and year in ArcGIS 10.2. Results: Of 60156 hospitalized patients with CAD diagnosis, men (58%) were more in number than women (42%). The majority of hospitalized patients fell in the age range 60-69 years (25.3%), and 92.40% of patients were hospitalized for less than 7 days. An ascending pattern was observed in temporal hospitalization trend in Khalkhal and a descending trend in Ardabil. The lowest hospitalization rate, however, was observed in Kosar city despite the ascending trend. During the research period, the greatest decline in hospitalization rate was observed in temporal trend in Bilasuvar, Meshkinshahrand Namin cities, and the largest increase was observed in Germi, Pars-Abad and Kosar cities. Conclusion: By using the comprehensive technology, GIS, spatiotemporal distribution and CAD trend during 2011-2015 were modeled in Ardabil province. Spatiotemporal trend of CAD in Ardabil province and allied cities indicated the necessity of paying more attention and studying community for further prevention of the disease. Community-based interventions should be implemented for prevention of risk factors of CAD during childhood and adolescence especially in the districts with high risk.

Background & objectives: Acne Vulgaris is a chronic inflammation of pilosebaceous glands. Some studies have indicated the significant decrease of linoleic acid in the sebum composition of the patients with acne. The aim of this study was to determine the probable therapeutic effects of linoleic acid on moderate acne. Methods: In a double-blind randomized clinical trial, 40 women with moderate acne were divided into two groups, each group with 20 each with 20 samples. After recording the nutritional and demographic factors, the case group received, 100 mg oral doxycycline daily plus 3 gr conjugated linoleic acid and the control group received 100 mg doxycycline daily plus 4-3 oral paraffin capsules as placebo for one month. The number of acne lesions were counted before and after treatment and the mean of Acne Severity Index (ASI) and Global Acne Grading System (GAGS) were determined for each group. The collected data were analyzed by SPSS software using chi-square, independent t-test and paired t-test. Results: The mean age was 22.8±5.5, in the case group and21.7±5.1 in placebo group indicating no statistically significant deference (p=0.51). At the end of treatment there was no statistically significant deference between the two groups in decreasing acne (p=0.31). During the treatment, ASI reduced from 129.5±13 to 77±11.6 in the case group and from 132±18.6 to 67.5±11.6 in the placebo group, –but there was no statistically significant deference between the two groups (p=0.37). Conclusion: It seems using 3 gr oral conjugated linoleic acid daily for 1 month has no effect on remission of acne.

ackground & objectives: Polycystic ovarian syndrome (PCOS) is a complex endocrine and metabolic disorder, which is characterized by ovulatory dysfunction and hyperandrogenism. Crocin is the main component of saffron. According to antioxidant properties and protective effects of crocin on gonads, this study was done to evaluate the effect of crocin on serum levels of gonadotropin, ß-estradiol, testosterone and ovarian follicle in a rat model of polycystic ovarian syndrome Methods: In this experimental study, 28 Wistar rats were divided into 4 equal groups. Including: control, non-treated PCOS and two PCOS groups treated with crocin (50 and 100 mg/kg). Polycystic ovarian syndrome was induced by 28 days injection of 1 mg/kg letrozole. Crocin was intraperitoneally administered into treated PCOS groups for 28 days. Saline solution was injected to the animals of control and non-treated PCOS groups. At the end of period treatment, serum levels of LH, FSH, testosterone and ß-estradiol was measured using ELISA. Then, ovarian tissue samples were stained with hematoxylin-eosin and histological changes were examined. Data were analyzed using one-way ANOVA and Post Hoc Tukey statistical tests (p<0.05). Results: Serum level of LH, testosterone, ß-estradiol and the number of cystic follicles in the PCOS group treated with 100 mg/kg crocin compared to the non-treated PCOS group significantly decreased and FSH, the number of preantral follicles, antral and corpus luteum significantly increased (p<0.05). Conclusion: Crocin has been effective in improving ovarian cysts and hormonal disorders in rats with polycystic ovarian syndrome.

Background & objectives: Human immunodeficiency virus (HIV) is a globally widespread infection that spreads mainly through sexual contact, mother to child and intravenous drug use. The disease can vary from an asymptomatic state to advanced immune deficiency and AIDS-related opportunistic infections and complications. Patients may be diagnosed at different stages of the disease. In this study, we aimed to analyze the clinical and epidemiological characteristics of patients with HIV and its consequences during the past 10 years (2005-2014) in Ardabil city. Methods: In this descriptive and case series study, patients with HIV (including live and dead patients) referring to the Ardabil behavioral counseling center were included during 2005-2014 years. The checklist containing demographic data, modes of transmission, time of diagnosis, clinical and therapeutic problems during this period, etc. was prepared for each patient. In dead patients, the causes of death as well as the interval between diagnosis and death were investigated. Results: In this study, 60 patients with HIV were evaluated, the mean age was 42.96 years, 76.7% of patients were male and 48.2% were intravenous drug users. In 39.7% of cases, patients have probably been infected through intravenous injection and 33.3% by sexual contact. The mean CD4 + lymphocyte cell count of patients was 252 cells per ml. The most common early symptoms of the disease were fever (63.33%), aphthous stomatitis (35%) and diarrhea (28.33%). In 7 cases (50%), tuberculosis was the most common opportunistic infection. 6 patients (10%) had coinfection with hepatitis B or C. 28 patients (46.6%) died within the time of study. The median time from diagnosis to death was 44.84±39.65 months and cardiorespiratory failure was the most common cause of death among patients. Conclusion: This study showed that most patients were middle-aged and intravenous drug use was the most common risk factors for HIV. The most common way of transmission was intravenous injection and hepatitis C and tuberculosis were the most important comorbidities, respectively. Raising community awareness about the disease, early diagnosis and appropriate care during illness are basic measures to deal with this global problem.

ackground & objectives: Epilepsy is a chronic neurological disorder that disrupts normal brain activity due to abnormal electrical discharge of brain cells. Mood swings, depression and anxiety are the common complications in epilepsy. The aim of the present study was to compare alexithymia in patients with Tonic-clonic epilepsy, Juvenile Myoclonic Epilepsy (JME), and healthy individuals. Methods: In this casual-comparative study, sampling was performed by convenience sampling method. The study population consisted of all epileptic patients and the study sample included 134 participants (N= 74 Patients and N= 60 healthy people) individuals aged 18-35 years. Among the patients, 14 were excluded due to lack of selection criteria and 60 samples (N= 29 with myoclonic and N= 31 with Tonic-clonic epilepsy) remained. Data regarding alexithymia was gathered by Toronto Alexithymia Scale, and analyzed by ANOVA, Scheffé post - hoc test and t-test were performed for independent groups. Results: Findings showed that the mean of Alexithymia in those with JME, tonic-clonic epilepsy and normal individuals were 64.44, 61.41, and 54.24, respectively. The difference between the two groups with myoclonic and tonic-clonic epilepsy was not statistically significant. However, there was a significant difference found between those with tonic-clonic epilepsy and normal individuals (T= 6.82; p<0.01). In addition, patients with JME and tonic-clonic epilepsy had more difficulty in identifying and describing emotions, and external thought direction compared to normal ones, while no such a difference was observed between the two groups with epilepsy. Conclusion: Epilepsy is accompanied by reduced processing of emotional information such as alexithymia. Individuals with tonic-clonic and juvenile myoclonic epilepsy are less qualified for recognizing and describing emotional information, and their intellectual orientation is mostly external. Also, since the location of discharge in both types is widespread and similar, no significant difference in alexithymia was observed between the patients with tonic-clonic and myoclonic epilepsy

Background & objectives: The relationship between dietary patterns and esophageal cancer has not been documented yet. However, recent studies have shown that the Western dietary pattern is associated with an increased risk of esophageal cancer. The current study was performed a comparative evaluation of the food habits and serum nitrate level in patients with esophageal cancer and healthy individuals in Gorgan city. Methods: In a case-control study, 44 patients with esophageal cancer (the case group) and 44 healthy subjects (control group) were selected for one year in Gorgan city. Anthropometric factors were measured, and then demographic and dietary data were recorded using general and food frequency questionnaires (FFQs), respectively. Fasting blood samples from both groups were collected to measure serum nitrate levels. Data were analyzed by independent t-test, Chi-square, Fisher, and Monte Carlo tests. Results: the mean weight, body mass index (BMI) and serum nitrate levels were statistically lower in the case group than in control group (p<0.05). Salt intake, smoking cigarette or hookah was higher in patients than in control group (p<0.05). Based on nutritional habits , consumption of bread , rice, saturated fats, hot tea, sausages and industrial soft drinks was statistically higher in the patient group than control group, but intake of vegetables, fruits, unsaturated fats, honey and grilled meat was lower in patients than control group (p<0.05). Conclusion: Consumption of fast foods, hot tea and saturated fats may be associated with esophageal cancer. Serum nitrate levels were lower in patients than control group, probably indicating the need for further research in this field.

Background & objectives: Terfezia Boudieri (TB) has been used as a sexual stimulant for men in traditional medicine. TB containing fatty acid, flavonoids, beta-carotene, minerals and antioxidants such as, catechin, therefore, this study aimed to investigate the effects of the hydroalcoholic extract of Terfezia Boudieri on sperm and testosterone levels in male rats. Methods: In this study, 21 adult male Wistar rats, each weighing approximately 250±20g, were randomly divided into three groups (n=7). The first group (control) with no treatment, the second group (sham group) received normal saline (extract solvent) and the third group, was injected intraperitoneally (IP) with 105 mg / kg of methanolic extract of Terfezia boudieri (TBME) (0.2 ml) for 21 days. The blood samples were collected to determine the concentration of testosterone and finally, the weight and size of the testicles and epididymis, the number and the percentage of sperm moving were evaluated Data were analyzed using ANOVA and Turkey s post- hoc tests. Results: The results of the present study showed that serum levels of testosterone, body weight of rat, testis weight, sperm count and sperm motility in the experimental group were significantly increased compared with the control group (p<0.001). Conclusion: The results of this study showed that TB at 105 mg/kg dosage can increase the levels of testosterone and improve sperm parameters and therefore, TB can be used to treat sexual impotence and infertility in males

Background & objectives: Syzygium aromaticum (Clove) is a medicinal plant usually used in traditional medicine to reduce toothache. The aim of the present study was to evaluate the analgesic effect of topical Clove oil on acute and chronic pain in male mice using formalin test. Methods: In this study, 24 mice were divided into 4 groups: control, morphine (as positive control), Clove oil, and Clove oil plus morphine groups. Before the formalin test, the animals were treated topically with clove oil for 6 hours. A single dose of morphine (10 mg/kg) was prescribed subcutaneously. Pain scores were obtained using the formalin test through an injection of 20 microliter of formalin 2.5% into the palm of the animals right hand. Results: Topical administration of Clove oil significantly decreased acute pain (the initial phase of the formalin test) and chronic pain (the second phase of the formalin test). Furthermore, topical Clove oil increased the analgesic effect of morphine in acute pain phase. Conclusions: This study showed that the analgesic effect of topical Clove oil was comparable to morphine.

Background & objectives: Diabetes mellitus is the sixth leading cause of death in individuals older than 25 years, and accounts for %18 of all deaths. The aim of this study was to investigate the TCD findings in diabetic patients with a history of less and more than 5 years. Methods: In this descriptive, analytic study, all diabetic patients were divided into two groups based on the duration of diabetes, less and more than 5 years after diagnosis. TCD was performed on the patients, and maximum velocity and mean pulsatility index and resistivity index in the right and left Middle Cerebral Arteries (MCAs) and basilar artery were measured. The checklist was completed for all patients, and all data were analyzed by SPSS (v16) statistical software. Results: Sixty four percent of the patients with duration less than 5 years (average age of 55.16 years) and 36 percent of those with duration more than 5 years (average age of 59.37 years) were men. There was no statistically significant difference between disease duration and Body Mass Index (BMI), but with an increase in duration of disease, HbA1C of patients was increased. There was no significant difference between the velocity of right, left and basilar arteries and diabetes duration. Also, there was a significant difference between diabetes duration and pulse index of right MCA and basilar. There was no significant difference between age, BMI and HbA1C and pulse and resistivity indexes among patients. Conclusion: In this study abnormal pulse and resistance indexes in patients with duration more than 5 years was more than patients with less than 5, this may indicate the effect of diabetes duration on the vascular wall.
