Histological Changes in Skin Tissues and Tissue Mast Cells of Rats after Irradiation of Ultrasoft Rays and the Effect of Pretreatment of Cysteine or Glutathione on Them.

Abstract

1. Distribution of mast cells in the skin and organs was tested. 2. Histological changes in skin tissues and tissue mast cells in mongrel rats were observed during 5 days after 2000 or 8000r irradiation of ultrasoft rays on the abdominal skin. 3. Histological changes in skin tissues and tissue mast cells in Wisterstrain rats were observed 3 days after 8000r irradiation. 4. Protection against histological changes in skin tissues and tissue mast cells was proved after intraperitoneal administration of cysteine 350mg per kg or glutaihione 600mg per kg 5 mill or 1 hour before 8000r irradiation.
