dc.description.abstract | Sprague•Dawley strain rats were irradiated once
with the doses of 100 rand 200 t on the 6th, 8th, 10 th and 12 th day of gestation. , Gross anomalies in the fetuses, weight, length and breadth of the brain of the live fetuses, survival rate of fetuses, changes of fetal body weight, and numbers of corpus luteum of maternal ovaries were studied after hysterectomy on the 22 nd day of gestation and the following results were obtained. 1. The gross anomalies were curled tail, short tail, and growth retardation of the limbs, anencephalus, and exencephalus. The abnormal tails were observed in the highest incidence throughout the anomalies appeared in the fetuses of experimental groups. The 8 th day of gestation seems to be the most susceptible to the effect of irradiation and the abnormal head (exencephalus, microcephalus and defect of the skull) appeared only in the group which received 200 r on the 8th day of gestation. 2. Weight of the fetal brain occured no change in the group which was irradiated on the 6 th day of gestation, but gradual decrease of the weight appeared in the groups which were received irradiation on the 8 th , 10 th and 12th day of gestation in orde r. More notable decrease resulted in the groups which received 200 I' than the group received 100 r. 3. Obvious reduction of the length of the fetal brain took place in the case given irradiation on the 12 th day of gestation in both groups which received 100 rand 200 r. 4. No significant change of the breadth of the fetal brain was observed at the group which received 100 r , but gradual shortening was visible in the results of the group received 200 r. 5. Most obvious decrease of the survival rate was obversed in the group irradiated with 200 I' on the 8 th day of gestation, but the later irradiation they received, the more decrease of the effect on survival rate were resulted. 6. No significant change of fetal body weight came out in the result of the groups received 100 1', but the later irradiation of the group which received 200 1', the more obvious decrease of the fetal weight were observed. 7. Numbers of the corpus luteum ,vere not effec ted by the irradiation. | - |
