Effect of acetylsalicylic acid on iron absorption in the rat

Summary The in vivo administration of⁵⁹Fe to the rat accompanied by acetylsalicylic acid (ASA) enhanced significantly counts in blood, spleen, liver and femur without affecting those of the intestine. The results suggest that ASA augments iron absorption either via an inhibitory action on the synthesis of prostaglandins or by a purely chemical mechanism.This work was supported by Grant No. 6638 from CONICET (Argentina).The technical assistance of Mrs María E. Castro and Mrs Patricia Dubra is gratefully acknowledged.     

Modification of clonazepam anticonvulsive activity by its association with other anti-epileptic drugs

Summary The modification of the anti-epileptic activity of clonazepam by other anticonvulsivants is studied. The results vary according to the drug and technique used. The usefulness of the 2 techniques employed is discussed.     

Effect of chemical sympathectomy,adrenalectomy and adrenergicα- andβ-blocking agents on the development of hyperglycemia induced by streptozotocin in the rat

Summary The sympathetic nervous system in the rat does not play any significant role in the streptozotocin-induced and tolbutamipe-induced hypoglycemia.
