[The effect of water soluble trichloromonofluoromethane freon on the weight and proteins of the heart muscle in Japanese quail].

An experiment was conducted to study the effects of water-soluble trichloromonofluoromethane freon (F-11, CC13F) on the weight of heart and on the level of freely extractable proteins in the heart of Japanese quail (Coturnix coturnix japonica). After three-week sublethal exposure of Japanese quail to the effect of freon the heart weight of the tested birds was found to have markedly decreased (however, the total body weight of the birds did not decrease). The tested quail also showed pronounced changes in the concentration of two protein fractions (an increase in one, a decline in the other), as determined by paper electrophoresis and polyacryl amide gel electrophoresis (however, the blood serum of the tested birds showed no changes in the levels of protein components).
