[Vitamin E levels in the ovine serum after administration of vitamin E and selenium].
The effects of drugs containing vitamin E for peroral administration (Combinal E), intramuscular injection (Erevit) and parenteral administration of a combined drug containing vitamin E and selenium (Selevit) on vitamin E levels in the ovine blood serum were studied. A uniform dose of 15 mg tocopherol acetate per 1 kg live weight was administered to the experimental animals. The level of vitamin E after the peroral administration of Combinal E was affected to a lesser extent than in swine and calves. The serum was examined before and after saponification to determine the effect of the intramuscular injection of Erevit; it was found out that tocopherol acetate prevailed in the blood serum in the first hours after such a route of administration. The best results were obtained after both subcutaneous and intramuscular administration of Selevit, the levels of free tocopherol showing high values even at the end of the experiments. These results may be made use of in determining effective preventive and therapeutic measures to do away with the white muscle disease in practice.
