[Fructose content and aldolase activity in the tissues of chickens under ultraviolet irradiation].

The effect of UV-irradiation was studied as applied to the content of fructose and activity of aldolase in the liver tissue and muscles of chickens and embryos obtained from eggs eight months after the chicken irradiation. It is established that the content of fructose and activity of aldolase in the tissues of 19-day embryos are approximately the same as in 40-140 day chickens. Under the effect of UV-irradiation the content of fructose in the liver increases in 140-day chickens and in embryos of the group under experiment, and it decreases in the muscular tissue of 80-day chickens. In the liver of embryos obtained from the irradiated bird the activity of aldolase lowers and in young chickens no essential difference is observed between the groups. The value of the ratio of the aldolase activity for both substrates in the liver of embryos and chickens of the group under study at the age of 40 and 140 days is somewhat higher than in the control, and in the muscular tissue it is lower (in embryos and chickens at the age of 40- and 80-days).
