[The role of daylight on the blood in the mechanism of the therapeutic effect of blood transfusion]. / Ro'l vozdeistviia dnevnogo sveta na kro'v v mekhanizme lecheb- nogo éffekta gemotransfuzii.

The authors studied the influence of daylight upon peroxidase activity and lipid content in neutrophils by means of cytochemical reactions in blood smears. In the experimental series of studies the blood was taken and stored without daylight. Control blood samples were kept under normal conditions. The studies have shown daylight to be a potent activator of redox processes and lipid metabolism in neutrophils. Similar effect upon peroxidase activity and lipid content in neutrophils is exerted by one calculated dose of long-wave UV rays, two doses inhibiting these processes. Taking and storing blood without daylight contributes to longer valuable morphological and functional condition of the formed elements.
