Different strains have different reaction to the delay of oviducts in body after animal death. After 10min delay C57BL/6 mouse oocytes have death rate of 56.5%,significantely higher than Kunming mouse (47.6%);Spontaneous activation rates were respectively 13.3% and 46.0%, C57BL/6 were obviously lower than Kunming mouse.4. The oviducts were obtained after being delayed 5min 24h after the mice were injected with hCG. The oocytes were cultured in CZB. About 81.1% occurred spontaneous activation, evidently lower than parthenogenetic rate (96.4%) with SrCl_2. Spontaneous activable oocytes had high cleavage rate(93.2%) and 4-cell rate(87.3%). However, spontaneous activable oocytes had blastula development rate(18.7%) as low as parthenogenetic oocytes by SrCl_2(22.9%).

不同品系小鼠卵母细胞对输卵管在体内滞留产生的反应不同，滞留10min C57BL/6系小鼠卵母细胞死亡率为56.5%，显著高于昆明鼠(47.6%)；自发激活率分别为13.3%和46.0%，C57BL/6系小鼠显著低于昆明鼠。4.hCG后24h体内滞留5min卵母细胞在CZB中培养自发激活率为81.1%，显著低于SrCl_2孤雌激活率(96.4%)；自发激活的卵母细胞有较高的卵裂率(93.2%)和4-cell比率(87.3%)，但囊胚率(18.7%)较低，同卵龄的卵母细胞经SrCl_2孤雌激活囊胚发育率为22.9%，差异不显著。

Spontaneous germ cell death is very important for the removal of germ cells and control of the quantity and quality of sperm. But excessive germ cell death will lead to diminish spermatogenic function and decrease the quality and quantity of sperm. Excessive germ cell death triggered by various regulatory stimuli, including deprivation of gonadotropins and intratesticular testosterone or by estradiol treatment in rats via apoptosis.

生精细胞凋亡是哺乳动物精子发生过程中的一个显著特点，其生理性凋亡对于去除受损的生精细胞，控制细胞数量和保证精子的质量具有重要意义，但生精细胞的过度凋亡可引起生精功能低下，使精子的数量和质量降低。

Western Blot indicated that AIF was selectively released before cytochrome C from the intermembrane space of mitochondria to cytosol, and that release needed Bax relocation to mitochondria. Results above suggest that caspase-independent cell death maybe occurred earlier than caspase-dependent cell death in staurosporine induced T lymphocytes apoptosis. Caspase-independent cell death is an alternative pathway of cell death which could guarantee the safe and noninflammatory removal of corpses when caspase was mutented or blocked in the cell, it plays an important role in maintaining the number of T lymphocytes and ensuring the proper function of immune system.

细胞caspase非依赖死亡方式可能是Caspase依赖性死亡方式的替代途径，它可以保证在Caspase发生突变或通路受阻时，T细胞仍然能够正常死亡，这对于维持T细胞的数量和保证免疫系统正常功能的发挥具有十分重要的意义。
