The effects of various hormones on the metabolism of acetate-i-C14 by rat adipose tissue in vitro were investigated. Using an albumin-containing medium, it was found that ACTH, growth hormone, epinephrine and glucagon each caused increased oxygen consumption, a decreased incorporation of acetate into tissue lipid, and an increase in the amount of newly synthesized lipid attached to albumin. The basic mechanism involved in the production of such qualitatively similar effects by each of the hormones studied are unknown.

SUMMARY The effects on lipolysis of various compounds have been studied in intact chicken adipose tissue and in isolated fat cells prepared from chicken adipose tissue. Glucagon stimulated lipolysis at concentrations down to 1 ng./ml. in intact pieces and 0·1 ng./ml. in isolated fat cells. The effect was enhanced by high concentrations of insulin. No anti-lipolytic effect of insulin was observed. Adrenaline, noradrenaline, porcine corticotrophin (ACTH) and long-acting ACTH were lipolytic but the effects were small and high concentrations were required. The adrenaline effect was blocked by propranolol hydrochloride. Dibutyryl 3′,5′-(cyclic)-AMP and theophylline stimulated lipolysis as did a combination of crude chicken growth hormone and hydrocortisone sodium succinate. It was concluded that the pattern of response of chicken adipose tissue was markedly different from that of the rat.
