Abstract
THE AIM of the investigation was to study specific changes of the main classes of membrane phospholipids and activity of some membrane-bound enzymes (Na/K-, Mg- and Ca- ATPases, 5’-nucleotidase) in radiation pathology. MATERIALS AND METHODS. The investigation was performed in white male rats with body mass 140-160 g. The animals were exposed to a single 3 Gr dose of general irradiation. On the 10th day after irradiation a microsomal fraction of the renal tissue cells was studied. The phospholipids fraction was performed by the method of thin-layer chromatography. Changes to the ATPase and 5’-nucleotidase activity were registered by the growth of non-organic phosphorus. RESULTS. Essential activation of 5’-nucleotidase and enhancement of total ATPase and Mg-ATPase activities in the renal tissue cells was established against the background of statistically reliable inhibition of Na/K-ATPase, as well as Ca-ATPase activities. The changes observed were accompanied by a significant decrease of the content of phosphatidilcholines with a simultaneous increase of the level of phosphatide acids, diphosphoglycerides and phosphatidilserines. CONCLUSION. Ionizing irradiation is characterized by a disturbance of the function of membrane-bound enzymes and redistribution of the qualitative and quantitative contents of phospholipids of the renal tissue cell membranes. The changes observed in the lipid-lipid and lipid-protein interrelations in the membranes of the renal tissue cells can cause a disturbance of the functional state of the kidneys.
