| Abstract: | Serum levels of 7 hormones and neuropeptides were studied in the course of development of a generalized epileptic activity (EA) induced in rats by intraperitoneal administration of corasole (75 mg/kg), i.e. 30 s (latent period), 50-150 s, 5-10 min after epileptogenic administration. A significant increase in the levels of ACTH (5.2-fold), glucagon (1.8.-fold), angiotensin I and renin activity were shown to occur 90-180 s later. Further on in the course of EA the level of ACTH remained enhanced but the level of glucagon and renin-angiotensin activity returned to normal. The levels of cortisol, vasopressin and aldosterone were enhanced 2-3-fold 30 min later. The level of insulin 30 min later remained unchanged. The role of neuropeptides and hormones in the onset and suppression of EA is discussed. |
