[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 fractions of nonspecific esterases were of predominantly tissue origin but after effort of serum origin. The results were discussed in connection with various mechanisms, which could cause proteinuria after physical effort.

[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. Changes in the brain and kidney were not recorded. Large protein fraction ammassments were observed in all the organs which interfered with the interpretation of electrophoregrams. Nevertheless, clear-cut changes after exertion were not disclosed. The isoenzymes of lactic dehydrogenase did not reveal alterations in the organs investigated after physical effort. A loss of non-specific esterase fractions at electrophoretic range from 0.4 to 0.6 was established in the liver of tired animals only.
