[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.
