A solution of Cs/sup 137/ was intraperitoneally injected into rats, and a quantitative examination was made of their spermatogenesis. For making calculation simple and arriving at a ready conclusion, the germ cell tubulus ratio or more shortly the germ cell ratio method was used. The germ cell ratio is the proportion of seminiferous tubules having spermatogonia, spermatocytes, spermatids, and sperm cells to all seminiferous tubuies in the same section of the testis. After the administration of 5, 50, and 200 mu C of Cs/sup 137/ the animals were sacrificed at various time intervals. The germ cell ratio of each type of germ cells was significantiy decreased, particularly in the 200- mu C- injected group. Even in the 5- mu C-injected animals, diminution of the germ cell ratio of each type of germ cells was slight but statistically significant with exception of the sperm cells which maintained a constant level of about 90 to 100% throughout the observations. It was estimated that the animals in the 5- mu Cgroup received a radiation dose of no more than 10 rad from internally administered Cs/sup 137/. (Abstr. Japan Med., 2: No. 12, Dec. 1962)
