[Free amino acids and peptides in the muscles of 1- and 2-day-old cadavers].

High-voltage electrophoresis and the analytic procedure combination of high-voltage electrophoresis--paper chromatography were used for the analysis of protein-free extracts of muscle tissue in one-- to two--day old corpses. The protein-free extracts from both types of tissue specimen were found to contain also peptides in addition to free amino acids. The amino acids composition of isolated fractions is not mutually comparable.

[Effect of ethanol and inderal on the heart cycle].

Ingested ethanol at a dose of 1.0 g per 1 kg of body weight in an experiment on healthy young men changes in the 30th minute the duration of individual phases of the heart cycle. By the effct of ethanol in the dose mentioned and by administration of 20 mg of Inderal, the negative inotropic effect in the 60th minute and by increased index of preejection period as well as by decreased volues of the index of tension of the left ventricular heart muscle.
