title: [Protective action of 21-aminosteroids in post-ischemic shock (splanchnic artery occlusion). Experimental model].
abstract: In anesthetized Wistar female rats a post-ischemic shock have been induced by splanchnic artery occlusion (S.A.O.). In these condition all animals died at 90 min., past release of occlusion and splanchnic reperfusion. 100% of pretreated rats with 21-Aminosteroids (U74389F) at doses of 1.5 mg.kg-1 survive over 3-6 hours, and 50% over 12 hours. Moreover, TNF alpha in these animals decrease significantly (p < 0.05). These results shown that 21-Aminosteroids can cause protective activity on lipoperoxidative damage in post-ischemic shock.
