| Abstract: | The authors investigated the effects of (+) cyanidanol-3-(Catergen) in vitro on the activities of rat brain plasma membrane and microsomal Na+-K+-ATP-ase and Mg++-ATP-ase, in the presence and absence of ascorbic acid. Due to lipid peroxidation induced by low concentration of ascorbid acid, activity of both ATP-ase decreased. (+) cyanidanol-3 proved to be an effective antioxidant in this system. It inhibited the decrease of ATP-ase activity which occurred as a result of lipid peroxidation promoted by ascorbic acid. |
