[Effect of erythrocyte membrane structure on the dose dependence of photohemolysis].

The influence of different factors modifying erythrocyte membrane structure on the value of power index of doze dependence of photohemolysis of hematoporphyrin-sensitized erythrocytes has been investigated. It has been established that thermoinduced spectrin aggregation results in increase the index, whereas vesiculation under metabolic exhaustion of erythrocytes greatly decreases value n. A more considerable decrease of the parameter was observed when photohemolysis of erythrocytes was occurred in alkaline medium.
