Abstract: Isolated rat adipocytes were incubated with adrenaline, adrenaline plus insulin, alloxan or alloxan plus insulin. Glycerol release was taken as a measure of lipolysis. It was observed that alloxan in the concentration of 3, 10 and 20 mmol/l intensifies lipolysis in adipocytes in the absence of adrenaline. Insulin (10-6 mol/l) treatment of cells did not inhibit lipolysis caused by this compound, but significantly restricted lipolysis induced by adrenaline (10-6 mol/l). It was also shown that alloxan in the concentration of 3 and 10 mmol/l intensified lipolysis stimulated by adrenaline (10-6 mol/l). Addition of 20 mmol/l of alloxan strongly inhibited glycerol release in the presence of adrenaline. The results presented here clearly indicate that the action of alloxan concerns cells of the white adipose tissue. |
