Bassam N. Aziz

Iraqi Journal of Pharmacy, Volume 9, Issue 1, Pages 1-8

Objectives: To study the effect of menopause associated with estrogen deficiency on lipid peroxidation products, such as malondialdehyde (MDA) with evaluation of some antioxidants like, glutathione (GSH) and its relation to lipoprotein levels in women living in Mosul City.
Design: Case-control study.
Setting: The study was carried out in Al-Salam Teaching Hospital in Mosul City, during the period from January 2008 to April 2008.
Patients and Methods: A total of 27 women aged 20–45 years were reported to be premenopausal and 42 women aged 45–60 years were recorded to be postmenopausal. Blood samples were collected for both groups. The assessments of serum malondialdehyde (MDA), glutathione (GSH), estrogen, arylesterase, calcium, total cholesterol, triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), and high-density lipoprotein cholesterol (HDL-c) were done.
Results: There were significant increase in MDA level in women after menopause in comparison with premenopausal age. On the other hand, GSH, estrogen, arylesterase, and calcium levels were significantly decreased. In respect to lipids, total cholesterol, TG, and LDL-c, were significantly increased in opposite to HDL-c, in which was decreased significantly in postmenopausal women in relation to premenopausal subjects.
Conclusion: The increase of MDA and the decrease of antioxidants concentrations like gluthathione, estrogen and HDL-c in postmenopausal women could contribute to acceleration of the cellular oxidative damage.

Iraqi Journal of Pharmacy, Volume 9, Issue 1, Pages 9-15

The contents of four ciprofloxacin tablets products available in the private pharmacies of Mosul city were measured according to the British Pharmacopoeia (BP). Some biopharmaceutical parameters such as content uniformity, disintegration, and hardness were also measured for the same products. In addition, the antibacterial activity of these four products were assessed by microbiological assay on different types of gram negative bacteria in vitro.
The results indicated that there is a little differences in the content uniformity of these products and they are within acceptable requirement of BP and United State Pharmacopoeia (USP). In the same manner, the weight variation, disintegration, and hardness were within acceptable range according to the BP and USP. The microbiological assay indicated that these different products produce approximately the same inhibition zones on the same bacterial type.
The above results may be useful to predict the bioavailability of these different products .

Lead is a neurotoxic metallic element that can be absorbed by the body, primarily through the lungs and stomach. Generally, lead poisoning occurs slowly, resulting from the gradual accumulation of lead in bone and tissue after repeated exposure. Left untreated, lead poisoning can damage many internal organs, including the kidney and the nervous system. Recent studies have shown that lead causes oxidative stress by inducing the generation of reactive oxygen species and reducing the antioxidant defense system of cells. This suggests that antioxidants may play an important role in the treatment of lead poisoning as a kind of scavengers of free radicals.
Antioxidant is any substance that reduces oxidative damage such as that caused by free radicals. Free radicals are highly reactive chemicals that attack molecules by capturing electrons and thus modifying chemical structures. Melatonin, a powerful antioxidant, is a hormone produced naturally in the pineal gland at the base of the brain.
This study was designed to evaluate the clinical significance of melatonin in ameliorating the oxidative stress induced due to chronic exposure to lead.
Twenty male patients with chronic lead poisoning and their 20 aged matched normal controls with an age range 35-45 years were included in this study. Treatment included 3 mg capsule of melatonin antioxidant at night for two months. Heparinized venous blood samples were collected from patients before treatment and at one and two months after treatment as well as from controls to measure erythrocytes malondialdehyde (RMDA), plasma total antioxidant status (TAS), blood lead (Pb) and serum zinc (Zn) levels.
The results of the study showed a significant antioxidant activity of melatonin in eliminating the oxidative consequences of lead exposure revealed by significant reduction in oxidative stress markers ( RMDA and Pb) with a significant increase in body antioxidant defense mechanisms(TAS and Zn).

Iraqi Journal of Pharmacy, Volume 9, Issue 1, Pages 21-31

In this study, two mutual azo prodrugs were synthesized for colon targeting in a treatment of colonic diverticular disease. The first was synthesized by coupling sulfamethoxazole with salicylic acid; the second was synthesized by coupling one mole of trimethoprim with two moles of salicylic acid. In vitro kinetic studies of these mutual prodrugs in hydrochloric acid buffer (pH 1.2) and in phosphate buffer (pH 7.4) were monitored. Hydrolysis of these mutual prodrugs was established in rat fecal matter. The release of 5-aminosalicylic acid and sulfamethoxazole or trimethoprim from these mutual prodrugs was almost complete and it followed first order kinetics. The prodrug approach to drug physico-chemical properties modification based on enzyme specifications may offer a new approach for improving drug product efficacy and reducing most of its adverse effects.

Iraqi Journal of Pharmacy, Volume 9, Issue 1, Pages 32-35

Objective: To evaluate the efficacy of synergistic activity of azithromycin combined with metronidazole against toxoplasmosis experimentally induced in murine model.
Material & Methods: Albino mice model (balb/c mice) acutly infected with tachyzoites, were treated for 10days from day +1 postinfection with administration of azithromycin combined with metronidazol.
Results: The results showed that prolonged survival of albino mice relative to that of untreated control, and the dead mice were found only in the control group. This experiment showed that a remarkable synergistic effect on toxoplasmosis was obsereved when azithromycin was adminstratered in combination with metronidazole at cuurative dosage i.e.(250 and 200 mg/kg/day), respectively. These results showed that azithromycin, which is remarkably active on toxoplasmosis, significantly potentiates the curative effect of metronidazol in the treatment. The treated mice in uncontrolled group were completely cured from toxoplasmosis as their brain were free of T. gondii cyst either microscopically or by bioassay.
Conclusion: Combined drugs of azithromycin and metronidazole showed a cure rate of 100% in experimental murine toxoplasmosis.

Iraqi Journal of Pharmacy, Volume 9, Issue 1, Pages 36-43

Objectives: To demonstrate the possible effect of smoking on serum uric acid level.
Methods: The study was conducted during the period from March to June 2008 in Mosul city as a case control study.
Participants: Subjects enrolled in this study were divided into two groups; nonsmokers and smokers composed of 47 and 40 apparently healthy male volunteers respectively with the same dietary habit, no pastmedical history of diabetes mellitus , hyperuricemia and gout , renal, lung or heart diseases or drug history affecting uric acid level. Smoker group is subdivided into heavy , moderate and mild smokers.
Fasting blood and random urine samples were obtained from both groups for measurement of uric acid and creatinine. Calculation of both urine uric acid/urine creatinine ratio and fraction excretion of uric acid were done.
Results: No significant differences in the age , serum creatinine , spot urine uric acid/urine creatinine ratio and fraction excretion of uric acid between two groups where as serum uric acid was significantly lower in smokers.
In smokers there are significant negative correlations of the average number of cigarette smoked/day and the duration of smoking with serum uric acid level.
Heavy , moderate and mild smokers showed no significant differences in the age , urine uric acid/urine creatinine ratio , fraction excretion of uric acid , serum creatinine and serum uric acid except a significant lower serum uric acid value in the heavy smoker compared with moderate and mild smokers .
Conclusion: The significant low serum uric acid level in smokers is due to the reduction of endogenous production as a result of chronic exposure to cigarette smoke that is a significant source of oxidative stress and as this reduction is proportionate with the duration and number of cigarette smoked/day and as low uric acid predispose to cardiovascular diseases as proved by other studies, therefore, its recommended for smokers to stop or reduce smoking with the use of serum uric acid as a routine test for follow-up as it is inexpensive , simple to reflect antioxidant level.

The study was conducted to record the prevalence and necessity regarding joint aspiration among patients with brucella knee arthritis and its role in the process of improvement. This study was a prospective analysis of 150 patients with musculoskeletal brucellosis (M-S brucellosis) recorded in the period from May 2005-July 2008 (39 months) in Erbil governorate, which cavers population of more than one million. Out of 150 cases; 30 patients who developed knee arthritis (20%) subjected to a comparative study and analysis to determine its prevalence and characters and the role of synovial fluid aspiration in the improvement. Out of the thirty; 18 patients (60 %) were females and 12 patients (40 %) males, the age group between 20-40 years. All patients met the criteria of the diagnosis and all patients were received anti -brucella antibiotic, 15 patients subjected to aspiration of the fluid and they were compared with reminders who were not subjected to fluid aspiration.
P value was not significant in both aspirated & non aspirated group after 6th, 8th, 10th and the end of the twelve weeks. In conclusion, M-S brucellosis is common in Erbil. Brucella knee arthritis represents about 20% of musculoskeletal manifestation of Brucellosis. Serial joint aspirations of synovial fluid did not play any role in the improvement of patients. Aspiration of synovial fluid may help in the diagnosis rather than a step for treatment.

In vitro inhibitory effects of selected anticholinesterase insecticides on human plasma and erythrocyte cholinesterases and their thermal reactivation

Omer A.H. Ahmed

Iraqi Journal of Pharmacy, Volume 9, Issue 1, Pages 58-65

The inhibitory effect of a number of locally used organophosphorus and carbamate insecticides on human plasma
and erythrocyte were examined in vitro by using the modified electrometric method for determination of
cholinesterase (ChE) activity. The negative logarithum of inhibitor concentration required for 50% inhibition
(pIC50) was estimated to range between -12.6 to 2.4 and between - 8.5 to - 0.77 for plasma and erythrocyte ChE,
respectively. Plasma ChE was more susceptible than erythrocyte ChE to effects of the insecticides. Thermal
reactivation technique was applied on plasma and erythrocyte ChE to identify and differentiate between
organophosphorus and carbamate insecticides
