Expression of testicular angiotensin-converting enzyme in adult spontaneously hypertensive rats.

Recent studies demonstrated that one isoform of angiotensin-converting enzyme named testicular or germinal (tACE) is localized in postmeiotic male germ cells and is essential for fertilizing ability of spermatozoa. Hypertension in spontaneously hypertensive rats (SHR) is androgen-dependent and reduction in male gametes is reported in this experimental conditions. Expression of tACE was not studied under conditions of spontaneous hypertension.

Aim: The aim of the present study was to analyze the effect of zinc on the activity of Cu/ZnSOD, lipid profile and arterial blood pressure in male Wistar rats.

Material And Methods: The study included 53 male Wistar rats with basal weight 190-210 g. The animals were divided into three groups and put on diets with different zinc content.
