[Effect of branched-chain amino acids on the irradiated body]

The administration to rats of amino acids (valine, leucine, and isoleucine) for 10 days after whole-body X-irradiation with a dose of 7 Gy increased the survival rate and average life of animals and normalized some carbohydrate and nitrogen metabolism indexes. The insulin-like effect of these amino acids on glucose absorption by phrenic muscles of the exposed rats was detected.
