The effects of inorganic selenocompounds (sodium selenite and selenate) on the level of reduced glutathione, free sulfhydryl groups of proteins and the activity of S-glutathione transferase (GST) in pig blood platelets were studied. It was shown that selenite, contrary to selenate reduced the amounts of both GSH and -SH of platelet proteins. The concentration of GSH after one-hour treatment of platelets with a high dose of selenite (10-4 M) was reduced by 50%. A decrease in protein thiols was also significant. We observed that the activity of platelet GST was inhibited after incubation of these cells with a toxic dose of selenite but not selenate.
