| The objectives of this study were to evaluate the effects of pinealectomy, adrenalectomy and pinealectomy-adrenalectomy upon the quantification of spermatogenic cells of rats. As such, 32 adult Wistar rats with a mean body weight of 331.7± 15.5g were assigned into one of the following treatments: (a) a sham-operated control group, consisting of nine animals; (b) ten pinealectomized animals; (c) seven adrenalectomized animals and (d) six pinealectomized plus adrenalectomized animals. No significant differences were observed between groups for the following parameters: body, testes, prostate and seminal vesicle weights, seminiferous tubular diameter, number of cells per seminiferous tubular cross sections (primary spermatocytes at pachytene, round... |

| We have shown that the renin-angiotensin system (RAS) is involved in glucose homeostasis during acute hemorrhage. Since almost all of the physiological actions described for angiotensin II were mediated by AT1 receptors, the present experiments were designed to determine the participation of AT1 receptors in the hyperglycemic action of angiotensin II in freely moving rats. The animals were divided into two experimental groups: 1) animals submitted to intravenous administration of angiotensin II (0.96 nmol/100 g body weight) which caused a rapid increase in plasma glucose reaching the highest values at 5 min after the injection (33% of the initial values, P<0.01), and 2) animals submitted to intravenous administration of DuP-753 (losartan), a... |
