[The antioxidative activity of homogenates and lipids obtained from intact and ischemic organs in rats].

The antioxidative activity of homogenates and lipids isolated from the brain, heart and liver was studied. The model of thermal autoxidation of linetolum in the presence of specimens studied was used. The antioxidative activity of lipids from the heart is higher than that of lipids from the brain. Ischemia of the organs leads to a practically complete loss of these qualities. The contribution of lipids to the general antioxidative activity of the tissue depends on the organ peculiarities. The contribution of lipids from the brain to the general activity is almost 10 times higher than that of lipids from the liver.
