Resumo
Local renin angiotensin (RAS) system has been described in the ovary, which has been implicated invarious reproductive functions. To evaluate the ovarian RAS in, 13 goats were randomly divided into two groups:Enalapril (n = 7) and control (n = 6). Then, they received superovulation protocol. Enalapril further groupreceived subcutaneously (2mg/kg) enalapril maleate (0.4 mg/kg/day). Blood samples were collected on days 3, 6, 9and 11, and follicular fluid samples from pre-ovulatory ovarian follicles after exposure by celiotomy on D11. AngII in serum and follicular fluid were evaluated on days 9 and 12, Ang-(1-7) on day 12 by HPLC and RIA. E2 andP4 concentrations in serum were determined by ELISA. Ang-(1-7) concentrations in plasma was greater on day9 (P < 0.05), important period for the recruitment and follicular selection. This may indicate that these peptidescan an important function in follicular development and oocyte maturation in superovulated goats.(AU)
