Action des Rayons Roentgen, du Cyanure et de Divers Radioprotecteurs sur les Infusoires

Abstract
A close parallelism exists between the resistance to roentgen irradiation and the resistance to cyanide of 4 species of histophagous infusoria (Ophrioglenidae). Histochemical studies on irradiated infusoria have shown changes only with regard to carbohydrates. Combination of cysteine and NaCN protects the Ophrioglenidae against the lethal threshold dose of X-rays. Other protectors (cysteins alone, cyanide alone, Na pyruvate and beta, beta-aminoethyl disulfide) have a weaker action and on certain species only.
