Probucol decreases total body fat loss in VX2-carcinoma-induced cachectic rabbits.

We previously reported the continuous decrease of total body fat in VX2-carcinoma-bearing rabbits after tumor implantation, as well as changes in the serum lipid profile. Probucol, an antioxidant drug, has a cholesterol lowering effect against hyperlipidemic subjects. VX2-carcinoma-bearing rabbits fed with a diet containing 1% probucol did not show any difference in serum lipid compositions as compared with rabbits fed with a control diet. Similarly serum lipolytic activity showed no differences, whether probucol was administered or not, while the decrease in total body fat was significantly less when probucol was administered.
