[Role of injuries to the vascular plexus in the development of a radiation lesion of the skin in swine].

A single action of beta-radiation of different energy on the swine skin was studied. The analysis and comparison of clinical and histological features of radiation injury to the mode of the absorbed dose formation associated with the depth of location of the skin structural elements permitted to consider deep vascular plexus of the dermis to be the second critical structure (in addition to basal layer of the epidermis) responsible for the radiation reaction development and for the rate and completeness of repair processes, in particular.
