  Aim:The total antioxidant capacity (TAC) and total peroxide (TP) levels in the blood and seminal plasma of idiopathic infertile patients were compared with those of fertile controls to determine the role of oxidative stress in the etiology of idiopathic male infertility.
Material and methods: Thirtytwo idiopathic infertile males and 30 healthy, married, agematched control subjects were included in the study. TAC and TP levels were measured in the blood and seminal plasma, and sperm parameters were studied in both groups.
Results: Sperm parameters were significantly impaired in the study group compared with the controls. Blood plasma TAC and TP levels in the patient group were 1.46 ±0.62 mmol Trolox equiv./L and 8.38 ± 0.87 mmol H2O2/L, respectively, compared with 1.72 ± 1.70 mmol Trolox equiv./L an ± 8.59 ± 1.08 mmol H2O2/L in the control group. Seminal plasma TAC and TP levels in the patient and control groups were 13.48 ± 2.03 mmol Trolox equiv./L, 7.79 ± 0.38 mmol H2O2/L, 14.06 ± 2.30 mmol Trolox equiv./L, and 7.84 ± 0.51 mmol H2O2/L, respectively. TAC and TP levels in the blood and seminal plasma did not differ significantly between the patient group and the control group.
Conclusion: These findings suggest that oxidative stress is not the cause of impaired sperm parameters in idiopathic infertile men.

  Aim:It is known that renin-angiotensin system, inflammation, signaling pathways, and genetic predisposition play a major role in the pathogenesis of heart valve disease. Scarring and collagen deposition in the valves and destruction of myocytes may result from the combined effects of rheumatic and degenerative process in heart valve diseases. Prolidase plays an important role in collagen metabolism, matrix remodeling and cell growth. The aim of the study was to comparatively assess the serum prolidase activity in rheumatic and degenerative heart valve diseases. Materials and methods: The study included 26 patients who had undergone valve replacement due to rheumatic etiology (Group I), 24 patients who had undergone valve replacement due to degenerative etiology (Group II) and 20 healthy volunteers (Group III). Prolidase activity was determined in all subjects. High sensitive C-reactive protein and white blood cell count were studied in only valve patients. Results:Prolidase activity was significantly greater in control group than in patients group (51.23.± 5.9 U/L vs. 39.40 ± 4.6 U/L, respectively; P < 0.001). There was no statistically significant difference between Group I and Group II (P = 0.721). No correlation was detected between serum prolidase activity and severity of valve disease (P > 0.05). Conclusion: These results suggested that rheumatic and degenerative heart valve diseases seem to be associated with decreased serum prolidase activity.
