Histological and Histochemical Changes Induced by Human Chorionic Gonadotropin on Prostate of Adult albino Rats | Author : Waleed H. Kasim; Maha A. Al-Sammak | Abstract | Full Text | Abstract :ABSTRACT
Aims of the study: To evaluate the histological and histochemical changes induced by
human chorionic gonadotropin (hCG) on the adult prostate and to correlate the changes
with the levels of testosterone.
Materials and Methods: eighty adult male albino rats were divided into 4 groups; 3
treated and 1 control. The treated groups were received 10, 50 or 100 IU/kg BW of hCG,
while the controls received normal saline. The doses were given twice weekly for 3
months via subcutaneous injections. Subsequently, on day 1, 30, 60 and 90 post therapy,
blood samples and the prostate glands were obtained for evaluation.
Results: All the doses of hCG caused accumulation of secretory products within the
prostate, which resulted in dilatation of the acinar lumens, reduction of the mucosal folds,
and non dose dependent diminution in height of the lining epithelial cells. Moreover, foci
of hyperplasic cells were observed in the prostate. The therapy increased the collagen
fibers of the gland. The general distribution of the Periodic Acid-Sciff (PAS) +ve
material was not altered. Most of these changes were reversible within 3 months.
Conclusions: Treatment with hCG causes accumulation of secretory products within the
prostate and in turn affects the structure of the prostate.

| Antidiabetic Prescription and Glycemic Control in Patients With Type 2 Diabetes Mellitus | Author : Isam Hamo Mahmood, Raghad Othman Ahmed Aldabbagh | Abstract | Full Text | Abstract :ABSTRACT
Objective: To detertmine the antidiabetic treatment among individuals with type 2
diabetic patients in Mosul city, the number of patients who attained the glycemic
target (good glycemic control) and patients who failed to attained glycemic target
(poor glycemic control) and to investigate factors that may be associated with poor
glycemic control.
Patients and Methods: 299 patients with type 2 diabetes mellitus of both sexes were
participated in this study. The patients were divided into 2 groups according to the
values of HbA1C: Group 1 (good glycemic control) and group 2 (poor glycemic
control). A questionnaire form was prepared to record detailed informations about
each patient such as age, drugs used, education level, diabetic family history,
adherence to treatment, exercise, and diet. HbA1c level was analyzed using high
performance liquid chromatography. Other parameters including total cholesterol,
high density lipoprotein-cholesterol (HDL), triglycerides, low density lipoproteincholesterol (LDL) and serum glucose concentration were measured using special kits.
Results: The antidiabetic drugs used including metformin, glibenclamide and
glimepiride, used alone and in combinations including metformin plus glibenclamide
and metformin plus insulin. Fifty patients (16.7%) have good glycemic control and
249 patients (83.3%) have poor glycemic control. Comparison between number of
poor glycemic control of metformin and glibenclamide showed non significant
difference. Comparison between poor glycemic control of metformin plus
glibenclamide and metformin plus insulin showed highly significant difference.
Comparison between mono-therapy and combination therapy showed highly
significant difference. High proportions of poor glycemic control were obtained with
ages >40 males, overweight and obese, low educational level, family history of
diabetes, use of herbs, long duration of the disease, low HDL-cholesterol, high
atherogenic index, non adherence to treatment, diet and exercise.
Conclusion: This study showed that high proportions of type 2 diabetic patients were
on combination therapy and the high proportions of the patients were poor glycemic
control. Many factors were found to be associated with poor glycemic control
including age >40 males, overweight and obesity, low educational level, family
history of diabetes, use of herbs, long duration of the disease, non adherence to
treatment, diet, and exercise. |
| Effects of Human Chorionic Gonadotropin on the Testis of Adult Albino Rats: A Histological and Histochemical Study | Author : Waleed H. Kasim; Maha A. Al-Sammak | Abstract | Full Text | Abstract :Aims of the study: To evaluate the histopathological changes induced by human
chorionic gonadotropin (hCG) on the adult testis and to correlate the changes with the
levels of testosterone, LH and FSH, as well as to assess their reversibility.
Methods: 80 adult male albino rats were divided into 4 groups; 3 treated and 1 control.
The treated groups were received 10, 50 or 100 IU/kg BW of hCG, while the controls
received normal saline. The doses were given twice weekly for 3 months via S.C.
injections. Subsequently, on day 1, 30, 60 and 90 post therapy, blood samples and the
testes were obtained for evaluation.
Results: Low dose of hCG caused increase in number of germ and Sertoli cells. Contrary,
higher doses decreased their population, and resulted in exfoliation of the germ cells.
Furthermore, reduction in the thickness of the tubular basement membrane, congestion of
the inter-tubular blood vessels and interstitial bleeding were observed in the higher dose
groups. All the doses caused interstitial oedema, hyperplasia and hypertrophy of Leydig
cells, as well as diminution in the collagen fibers. All these changes were reversible
within 3 months.
Conclusions: Only the low doses of hCG stimulate the spermatogenesis, whereas higher
doses suppress sperm production. |
| Fluorine important element in new drugs synthesis: Review Study | Author : Ahmed A. Mahmood; Mohammed A. Al-Iraqi; Faris T. Abachi | Abstract | Full Text | Abstract :Objective:To evaluate the role of fluorine atom in modern drug synthesis.
Methods: Different types of fluorinated were prepared, antimicrobials, antivirals, FNSAIDs, peptides and protein synthesis.
Results: Recent developments and future prospects of fluorine in medicinal chemistry
and chemical biology. The extraordinary potential of fluorine - containing biologically
relevant molecules in antimicrobial or antivirial agents, or peptide or protein
chemistry, medicinal chemistry, chemical biology, pharmacology, and drug discovery
as well as diagnostic and therapeutic applications, was recognized by researchers who
are not in the traditional fluorine chemistry field, and thus the new wave of fluorine
chemistry has been rapidly expanding its biomedical frontiers.
Conclusion: This review how to list of fluorinated drugs( Antimicrobial agents ,
anticancer agents, Antiviral agents, and study their physicochemical properties of
fluorine drugs.

| Anti-adhesion therapy, a promising alternative in the infections treatment | Author : Waleed Khalid Madle; Mohammed Abdullah Ajeel; Muhammad A. Alkataan; Akram Abdullah Ajeel; Wijdan I.A. Abd-alwahab | Abstract | Full Text | Abstract :Objective: Antibiotic resistance (AR) represents one of the most important health problems
worldwide due to the fact that it significantly lowers the number of effective antibacterial agents.
Many mechanisms were studied to reduce emerge of AR, one of these is the use of Anti adhesion
Methods: keywords were used to search for Most of the subject available articles. Following that, a
grammatical examination was done for the vocabulary associated with the literature review.
Results: Anti-adhesion agents represent a vital approach to stop or treat bacterial infections. These
agents focus on bacterial virulence and pathogenicity properties (e.g. adhesion and
colonization). These agents considered a perfect alternative for an antibiotic, with the infectious
process inhibiting an advantage in the first step to reduce the damage. These agents inhibit bacteria
attachment to the surface of the host cell by interfering with the assembly of the host receptors,
bacteria-host cell assembly or adhesion biosynthesis. Bacterial adhesions antibodies can prevent
surface epitopes required for bacteria-host cell attachment by the application of anti-adhesion
strategy to decrease AR or reduce the need for effective antibiotic doses .
Conclusions: Anti-adhesion therapy includes efforts for preventing adherence, reduces
virulence, and biofilm formation. These have advantages over classical antibiotics through
blocking pathogenicity without destroying bacteria and it also has a synergistic effect when
applied with antibiotics |
