ricinoleic acid/diarrhea

Effects of loperamide on diarrhea induced by castor oil and prostaglandin E1 were investigated in rats and mice and compared with those of narcotic analgesics, atropine, mecamylamine and local anesthetics. The following results were obtained. Loperamide markedly suppressed the appearance of diarrhea

To examine the role of extrinsic nerves and hormones in intestinal secretion of fluid, we studied the effect of ricinoleic acid on absorption by isolated, autotransplanted jejunal loops in four dogs. Compared to perfusion with control solution, the addition of ricinoleic acid caused reversible

The appearance in plasma of sulphapyridine after oral administration of salicylazosulphapyridine (Salazopyrin) was shown to be useful for measuring the orocecal transit time in normal subjects. The purpose of this study was to use this method in diarrhea with accelerated intestinal transit time. A

Castor oil is one of the oldest drugs. When given orally, it has a laxative effect and induces labor in pregnant females. The effects of castor oil are mediated by ricinoleic acid, a hydroxylated fatty acid released from castor oil by intestinal lipases. Despite the wide-spread use of castor oil in

The mechanism of the diarrheogenic effect of bile acids and fatty acids is incompletely understood. In order to study their effects on motility we tested sodium deoxycholate and sodium ricinoleate in their actions on the spontaneous mechanical and myoelectrical activity of the isolated circular

The influence of fatty acids on ileal absorption of water, electrolytes, glucose, and taurocholate was examined in Thirty-Vella fistulas in five mongrel dogs. Fatty acid absorption also was measured. Segments of terminal ileum were perfused at steady state with isotonic electrolyte solutions

Unabsorbed dietary unsaturated fatty acids may cause diarrhea in patients with steatorrhea, but their ability to cause colonic fluid secretion is not known. The present study investigated the effect of several dietary long-chain unsaturated fatty acids on colonic absorption and morphology in the rat

Certain nonsteroidal anti-inflammatory drugs (NSAID) of the fenamate chemical class are known to cause diarrhea in clinical use. Paradoxically, this action is shared by prostaglandins, against whose syntheses are inhibited by NSAID. This study was done to investigate the laxative potential of 5
