[Evaluation of radiation damage to rat and dog erythrocyte membranes based on changes in their sedimentation properties].

It was shown that injury to plasma membranes leads to a change in the sedimentation behaviour of erythrocytes: the maximum effect is produced when a protein component of the membrane is affected. The same dose-dependent character of the change in erythrocyte sedimentation in urografin is observed during the first 24 h after gamma-irradiation of rats and dogs.
