title: Studies on reduction of lipolysis in adipose tissue on freezing and thawing.
abstract: Adrenaline-induced lipolysis in fat cells was remarkably reduced when the cells were preincubated in a dry ice-aceton bath, but their adenylcyclase and lipase activities were not reduced. In the reconstructed lipid micelles which consisted of lipase-depleted lipid micelles and lipase-containing adipose tissue extract, adrenaline, theophylline and DBcAMP-induced lipolysis was not found when lipase-depleted lipid micelles were preincubated in a dry ice-aceton bath but was found when lipase was preincubated.
