RESUMO
PURPOSE: The effect of physical exercise on lipid peroxidation was investigated. METHOD: 27 healthy young adult male subjects were included in this study. Urine samples were collected before and after exercises. Urinary malondialdehyde and creatinine levels (Cr) were measured. RESULTS: Urinary malondialdehyde levels were increased by exercise. While pre-exercise malondialdehyde levels were 5.02 +/- 1.26 nmol/mg Cr, post-exercise levels were 6.13 +/- 1.84 nmol/mg Cr (p < 0.05). CONCLUSION: These findings indicated that physical exercise induced lipid peroxidation.

Primary carcinoma arising in the urothelium of the ureter is rare, accounting for only 1% of all cancers of the upper urinary tract. We describe a case in which primary transitional cell carcinoma of the right ureter was sonographically detected in a 45-year-old woman. The mass exhibited tumoral vascularity on power Doppler sonography and spectral analysis.

Electrically induced bulbocavernosus (BC) reflexes were investigated in 47 patients with benign prostatic hypertrophy and the possible harmful effects of prostatectomy on the pudendal nerve branches were followed up in 30 of the patients using the same method. BC reflex obtained by electrical stimulation of the glans penis did not differ significantly from the normal value in bulbocavernosus and external urethral sphincter muscles whether or not patients had been operated on. It was concluded that there is no reason to believe in the existence of somatic involvement of the pudendal nerve branches in prostatic hypertrophy, or that suprapubic prostatectomy could harmfully affect such somatic nerve fibers.
