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.

Methods①The animal model of braincontusion caused by free drop hammer was established.②The injuredtissue of rat brain were stained by TUNEL for apoptosis,immunohistochemistry for Caspase-3 and Feulgen"s for DNA. Image analysistechnique and the statistical method were employed to explorate thetemporal changes of injury time.③The DNA was extracted from ratcontusive tissue of brain and assayed by gel electrophoresis toinvestigate the relationship between the DNA fragmentation and injurytime.④One handred and seventeen cases of death from traumatic braininjury were retrospective researched to investigate the characteristicof TBI in forensic medicine.⑤The contusive tissue of human brain werestained by TUNEL, Caspase-3 immunohistochemistry and Feulgen"s methodsin the same way to analyze and disclose the linear relationship betweentemporal changes with injury time.

方法①建立大鼠自由落体打击脑损伤模型；②对不同损伤时间组的大鼠脑挫伤组织进行TUNEL、Caspase-3免疫组化、Feulgen's DNA染色，结合图像分析技术和统计学分析，探讨脑挫伤后神经细胞凋亡、DNA片段化和含量的时序性变化；③提取大鼠脑挫伤组织DNA进行琼脂糖凝胶电泳分析，观察DNA片段化随损伤时间的变化特点；④对117例颅脑损伤致死案例进行回顾性分析，探讨其法医学特点；⑤选择不同损伤时间的人脑挫伤组织同样进行TUNEL、Caspase-3免疫组化、Feulgen's DNA染色和分析，观察上述指标与损伤时间的关系。

Coalition members described the abuses as a 'silent holocaust' because the weapons deployed are so poorly publicised, and because individuals are dying as a result of deployments of directed energy weapons, and other deniable abuses of human rights that were also discussed during the conference.

联合的成员把这种虐待描述为一种&沉默的屠杀&，因为武器的配置很少被公开，并且受害者会被这种定向能武器致死，以及其他可否认的对人权的侵害，也在会议期间被讨论。

The preliminary localization of lethal lesions in in-jured brain-stem indicated that,lesions in the neural structure concerning the respira-tory center and cardiovascular center might be the cause of death,which were prin-cipally on or close to the line linking the posterior angle of fourth ventricle at thedorsal surface and interpeduncular fossa at the ventral side.

Passive transfer of sera from mice immunized with expressed G1 and G2 conferred partial protection or prolongation of time to death from fatal hantaan virus infection in infant mice which challenged with hantaan virus at 10LD50. The spleen cells from mice immunized with G1, G2and NP can protect or prolongate the lifetime of infant mice infected with lethal dose (10LD50 or 40LD50) hantaan virus.

本文比较了具有多种毒性作用机制的取代苯酚对两栖动物幼体的急性致死性毒性、对高等植物生长的抑制毒性以及对原生动物—四膜虫的种群生长抑制毒性，探讨了这一类污染物的毒性作用机制，进行了种间相关性研究。

Model of animals were established by putting rats in a container with slippy inner wall and half-full of water in it, letting them swimming freely till died of being drowned. Each rat from different groups was killed by breaking its neck except drowning group, then BW and SO_2 was detected, and its chest was cut open rapidly, lung was taken out and weight was measured accurately to count lung coefficient. Its lung appearance was observed and lung tissue was fixed with formalin, which was made into pathology slices with HE staining, and pathology change of the lung tissue was observed;Expression of IL-8 and IL-10 in lung tissue was detected with Immunocytochemistry, and correlation between them was analyzed .
