Effects of gamma irradiation on shoot regeneration from leaf and bud growth in vitro of strawberry 1 The leaf was very sensitive to the gamma irradiation, and 'Toyonoka' was more sensitive than 'Akihime'. The LD50 (50% decrease of generation) of strawberry leaf was between 10 and 20 Gy. 2 Strawberry leaves were inoculated in vitro at 8 d-15 d after gamma rays irradiation, and the shoot regeneration rate from of 'Toyonoka' increased at 10 Gy and almost no difference from 20 Gy to 40 Gy. The positive effect dose for 'Akihime'.was from 10 Gy to 30 Gy, however, 40 Gy decreased shoot regeneration rate.

In result 2.5% of the rats got slight hepatic enzymes increase, and 6.25% of the rats got slight fat degeneration for hepatic tissue specimens. Most of the rats with abmormal results occurred in the toxic and lethiferous group, and there was the increasing tendency with the increase of dose. There were no changes for renal function and tissue biopsy.

Take the blood specimen to measure the hepatic and renal function and the tissue biopsy after the active and motive abnormities called toxical manifestation such as posture changes, abnormal sound, uneasiness, quiet, thrill, ataxia, convulsion and so on with toxic dose. Measure the tissue biopsy after death with lethiferous dose. If no toxicity or death occur after the experiment of 12 weeks, measure the hepatic and renal function and the tissue biopsy. There was no rat which had the toxical manifestation such as active or motive abnormities and 3 rats died because of environment or others after the experiment of 12 weeks.
实验中分别测定治疗剂量组小鼠在用药4周，8周，12周后的肝肾功能，并进行组织病理检查；中毒剂量组小鼠在出现行为、动作异常，如改变姿势、叫声异常、不安、安静、震颤、运动失调、惊厥等中毒表现时，取血液标本测定肝肾功能，并进行组织病理检查；致死剂量组小鼠发生死亡后进行组织病理检查；若12周实验结束时无小鼠出现中毒表现或死亡，则取血液标本测定肝肾功能，并进行组织病理检查。12周实验结束时，无小鼠出现动作、行为异常等中毒表现，有3只小鼠因为环境或其它原因发生死亡，病理检查结果正常。

After twenty-one days, they were challenged by white spot syndrome virus. The mortalities of crawfishes after challenged with WSSV of the same dilutions were negatively correlated with the the dose of Ig-Guard, that is, along with the increase of the dose of Ig-Guard, their mortalities were decline; The LD50 of the immune group was higher than the control group, further more, along with the increase of the dose of Ig-Guard, the effectes were obvious.

The seeds of Adzuki bean were irradiated by 60 Co γ ray of 0～700Gy.The results showed that:(1)The sub\|lethal dose(LD 50 )was 389Gy and the early seedling leaf at M\-1 showed incised,chlorotic,yellow,mosaicand curly edge.The absorbed dose was related with the rate of misshaped leaf.Chromosomal aberration, chromosome bridge and fragment of M\-1 in the tip were observed.If the seed was irradiated with 400Gy,the rate of abnormal cell at the root was more than 10%.The relationship between pollen fertility and irradiation dose was negative correlated.
