    Notes: [Auszug] Mice of pure breed (C 57 black), four to six months old, were exposed to X-rays in groups of ten, in a cardboard box 10 cm. x 10 cm. Physical constants : 250 kV., 18 mA., copper filter 0 -25 mm., focal distance 50 cm., field 150 cm.2, mean output 90 r./minute. A first control group of mice ...

    Notes: Summary Using an appropriate technique, we put adults rats of both sexes under deep hypothermy (rectal temperature of 14–15°C). Under these conditions, the respiration and the cardiac rhythm are definitely slowed down. (1) Rats irradiated in a state of deep hypothermy with lethal doses of 800 and 900 r of X-rays, are partially protected. 50% of these animals survived more than 30 days, whereas all control animals died after 17 days. (2) The same degree of protection is obtained if the cooling is made in the presence of oxygen or under an air pressure of 1.25 atmosphere.

    Notes: Summary The cystinamine (1591) Labaz which efficiently protects the life of mice irradiated with a lethal dose of 900 r, fatal for unprotected animals, and allows the complete recuperation of the lymphoïd tissues of these animals, is however unable to prevent ovarian atresia. This is probably due to the fact that this amount of 900 r greatly exceeds the sterilizing dose.
