Objective: The aim of this study was to determine the effect of indomethacin, an anti-inflammatory agent, on apoptosis and crystal deposition developing as a consequence of tubular cell injury induced by hyperoxaluria in an animal model. Materials and methods: Fifty New Zealand rabbits were divided into 3 groups. The first 2 groups were fed with hyperoxaluric diet and Group 3 was the control group with no supplementary procedure or treatment. While the animals in Group 1 were given only hyperoxaluric diet, Group 2 animals was applied indomethacin in addition to the hyperoxaluric diet. Animals were sacrificed at the early (7th day) a . . .nd late (28th day) periods and renal tis-sue specimens were sent for the pathological analysis of crystal deposition and apoptosis. Results: The presence and degree of crystal deposition were significantly less in the specimens obtained from indomethacin-treated group during both the early and late periods ( Daha fazlası Daha az

The objective of this study is to assess the efficacy of an alpha-1 adrenergic receptor blocking agent on the spontaneous passage of proximal ureteral calculi ?10 mm. 92 patients having single radio-opaque proximal ureteral stone ?10 mm were randomized into two groups. Group 1 patients (n = 50) were followed with classical conservative approach and patients in Group 2 (n = 42) additionally received tamsulosin, 0.4 mg/day during 4 weeks follow-up. The stone passage rates, stone expulsion time, VAS score, change in colic episodes, and hospital re-admission rates for colicky pain were compared. The patients were furthermore stratified . . .according to stone diameters Daha fazlası Daha az

Objective: To compare the factors affecting sexual function in premenopausal women with type 2 diabetes using the female sexual function index (FSFI). Design: Cross-sectional study. Setting: Premenopausal women with type 2 diabetes and healthy volunteers in an academic research environment. Patient(s): Sixty-two type 2 diabetic women were compared with 50 controls. The FSFI scores of the patients were compared according to age, duration of diabetes, marriage, socioeconomic status, parity, menstruation regularity, body mass index (BMI), and smoking. Intervention(s): None. Main Outcome Measure(s): Female sexual function index scores. . . .Result(s): The mean FSFI score in diabetics was lower than in controls. Menstrual irregularity and duration of diabetes affected female sexual function unlike age, BMI, socioeconomic status, duration of marriage, or parity. Regularly menstruating women had higher FSFI scores (27.1 ± 6.7) than irregularly menstruating women (20.7 ± 7.4). Type 2 diabetics were divided into three groups according to duration of diabetes. The women having diabetes longer than 10 years had the worse sexual function. Also, smoking affected inversely female sexual well being. Conclusion(s): Menstrual disturbance, smoking, and longer duration of diabetes (more than 10 years) impair FSFI scores in premenopausal women with type 2 diabetes.

We investigated the effect of intraperitoneal vardenafil (1 mg/kg) administration during an ischemic period in a rat model of testicular torsion/detorsion (T/D). Twenty-one adult Wistar rats were equally randomized into a control group, a T/D group and a vardenafil group. The control group was designed to collect basal values for biochemical and histopathological parameters. The T/D group underwent testicular torsion for 1 hour. The vardenafil group received vardenafil (1mg/kg) intraperitoneally at 30 minutes after torsion. All rats were sacrificed 4 hours after reperfusion to evaluate the tissue levels of malondialdehyde and total . . .antioxidant status. Germ cell apoptosis was evaluated using the apoptosis protease activating factor 1 antibody in all groups. The expressions of endothelial nitric oxide synthase (NOS) and inducible NOS were also assessed in both testes of all rats. The malondialdehyde levels in the T/D group were significantly higher than in the control and vardenafil groups. There were also significant decreases in total antioxidant status in the T/D group compared with the control and vardenafil groups. Vardenafil treatment significantly reduced apoptosis protease activating factor 1, endothelial NOS and inducible NOS levels in the vardenafil group compared with the T/D group. Administration of 1 mg/kg vardenafil during testicular torsion decreased ischemia/reperfusion cellular damage. Our results indicate that the reduction in oxidative stress by vardenafil may play a major role in its cytoprotective effects. © 2009 Elsevier Daha fazlası Daha az
