The results showed that taurine has no significant influence on testis index, epididymis index, spermaduct index, penis index and testis tectology of baby and young rats, but can make old rat testis tectology better, prevent convoluted seminiferous tubule degeneration, germ cell distortion and leydig cell atrophy. Taurine increase the level of T, E2 and LH in baby rat obviously, but has no significant effect on the level of FSH. The level of T and LH was obviously increased by taurine in young and old rats, but the level of E2 and FSH has no significant changes.

结果证明：牛磺酸对幼年、青年、老年大鼠睾丸指数、附睾指数、输精管指数和阴茎指数没有明显影响；对幼年、青年大鼠睾丸组织形态没有影响，但可明显改善老年大鼠睾丸组织形态，阻止曲细精管退化、生殖细胞变形和间质细胞萎缩；显著促进幼年大鼠 T 、 E2、 LH 分泌，而对 FSH 没有明显影响；明显促进青年和老年大鼠 T 和 LH 分泌，而对 E2和 FSH 没有明显影响。

To detect effects on apoptosis of cortex neuron in DHCA rats, the rat model of occluding bilateral common carotid artery in the deep hypothermic (21C) rats had been established, and flow cytometry, TUNEL, electron microscope, immunohistochemistry and RT-PCR had been studied.: part I: To establish a new rat model of cerebral ischemia/protect during DHCA: 20 SD rats were used in the experiment, little animal respirator was to assist anesthetized rat's respiration after tracheal cannula, artery press through artery spile in femoral artery, electrocardiograph, temperature, blood saturation of O2 (SaO2) and arterial blood gases were monitored during the whole experiment, blood flow of bilateral common carotid artery of rat were occluded about 60 minute when its temperature was reduced to 21 C by ice, then normal temperature was resumed.
