Effect of salicylate and adrenocorticotropin on the hepatic and serum cholesterol in catfish, Heteropneustes fossilis (Bloch).

A single injection of salicylate or salicylate plus ACTH was able to lower the hepatic cholesterol content within one hour after the treatment. However, their daily injection for eight days caused significant rise in the hepatic cholesterol. ACTH alone could not significantly alter the liver cholesterol content after similar treatment. A single injection of salicylate produced hypocholesterolemia within one and three hours after the treatment. ACTH or salicylate plus ACTH also brought about 50 per cent reduction in serum cholesterol level from its initial control value within one hour. Similar treatments, however, raised the serum cholesterol after three hours. The rise in the serum cholesterol level was about twofold in animals five hours after salicylate plus ACTH treatment. Daily administration of salicylate, ACTH or salicylate plus ACTH for eight days caused, however, hypocholesterolemia.
