Repair and biochemical protection in life shortening of mice exposed to fractionated X-irradiation.

Male mice of the BALB/c+ strain were exposed to X-rays at fractionation intervals of 7, 15, 30, and 60 days. One group received a mixture of radioprotectors, another AET (only 30 days fractionation), a third one served as control. The doses ranged, dependent on the treatment, from 300--1500 R. When survival was corrected for acute death, the control and AET treated animals died after an accumulated dose of about 2000 R whereas those treated with a mixture of radioprotectors died after about 4000 tr. Bone marrow failure and lung damage is the main cause of death within the initial 200 days after start of the exposure. At later times, fibrotic changes and in particular glomerulosclerosis are observed.

[Lead toxicity in mice embryos].

Administration to female mice before coïtus and to pregnant female mice of an alimentation containing 0.1 p. 100 lead acetate imparied the fertility. Studies on the changes of the ultrastructure of the embryos during the first stages of development do not allow to detect lesions unless on day 7 where lead inclusions are detected in the mitochondria.

[A and C particles in mouse embryos].

Electron microscopic examination of embryos of the BALB/c and AKR strains of mice from the 1-cell stage to 14 days of age revealed 2 types of intracisternal A particles, one type of C particle budding into the extracellular space and an endoplasmic reticulum-association "dense-cored veiscle". The occurrence of the particles showed a marked dependence on the developmental stage of the embryo. A small percentage of 1 blastomere embryos in both strains showed the presence of a small number of A particles. Embryos of 1 to 16 blastomeres of the AKR strain with A particles were on average more frequent than in the BALB/c strain. The percentage of 7 and 14 day embryos with C particles was much greater in AKR than in Balb/c mice.
