[Disc electrophoresis of urinary proteins. Changes after exertion].

The authors examined, by means of disc electrophoresis, urine, obtained from football players before and after a match of the championship of the "A" republican football group. Proteinuria after effort was manifested by a considerable excretion of albumin, but there were also serum proteins: postalbumin, transferin, gamma-globulins and fractions found at the place of alpha2-macroglobulins till a complete resemblence of serum electrophoresis. Electrophoresis of lactate-dehydrogenase revealed the presence only of two quick fractions, mainly LDH-1, which increased after effort as well.

[The effect of acute fatigue on organ proteins and protein fractions].

Fatigue till exhaustion and renunciation was caused in rats through forced loaded swimming performance. Changes in watersoluble protein, in its fractions separated by means of disk electrophoresis, as well as in the fractions of lactic dehydrogenase and non-specific esterases were searched for in the different organs. Insofar water-soluble protein is concerned, a statistically reliable increase was found in the liver and heart chamber musculature, and reduction - in the skeletal muscles.
