T739 mice were inoculated with LA795 cells. Angiostatin was given to part of inoculated and uninoculated mice by intraperitoneal injection fourteen days after the inoculation. The treatment lasted 20 days and the size of tumor, survival period, behavior of the mice and pathology of lungs, livers and kidneys were observed.

用亲和层析方法得到的血浆纤维溶酶原经胰蛋白酶消化、层析柱亲和层析、透析，得到纯化的血管抑素；以LA795细胞接种于T739小鼠；接种后第15日起腹腔内注射血管抑素共20 d，观察动物行为，测量荷瘤鼠肿块直径，记录生存期，另设未治疗对照组及观察血管抑素副作用对照组，行肺、肝、肾脏病理学检查。

Methods Affinity chromatography purified plasminogen was digested by pancreatic elastase and angiostatin was obtained by purifying the digestion with affinity chromatography and dialysis. T739 mice were inoculated with LA795 cells. Angiostatin was given to part of inoculated and uninoculated mice by intraperitoneal injection fourteen days after the inoculation. The treatment lasted 20 days and the size of tumor, survival period, behavior of the mice and pathology of lungs, livers and kidneys were observed.

Fter different detraining cycles on the physiological performance, the detraining cycles will be reflected different degrees of impact. We found that the strength and endurance of athletes in detraining has reduced the capillary density, oxidative fibers, slow-twitch muscle. On the other hand, AVO2-diff, oxygen enzyme decline in the number of mitochondria, the change of muscle fiber types and reduced neuromuscular control in long-term detraining. In cardio-respiratory fitness, particularly in endurance athletes among blood flow, plasma volume, and cardiac output's decline are the most conspicuous. After hormone and metabolic's short term and long-term detraining, we found that growth hormone, testosterone, cortisol, respiratory exchange rate, showed a decline in insulin sensitivity, it will directly affect the exercises performance. Further more, the exercises performance and physiological benefits could have been completely eliminated.

bstract 不同周期停止训练后，对生理表现将反映出不同程度之影响，其中发现肌力性与耐力性运动员在短期停止训练后，毛细血管密度、氧化纤维、慢缩肌呈现减少情形；反观长期停止训练后，将会使动静脉血含氧差异(arterial-venous oxygen difference， AVO2-diff)、氧化酶粒腺体数目下降与肌纤维型态之改变，而减少神经肌肉控制能力、在心肺适能方面，尤以耐力性运动员在血流量、血浆量、每跳输出量、最大心输出量下降情形最明显；而贺尔蒙与代谢在短期与长期停止训练后，发现生长贺尔蒙(growth hormone， GH)、睪固酮、可体松、呼吸交换率、胰岛素敏感性均呈现下降情形，这些情形将直接影响其运动表现之发挥，甚至使先前获得之运动表现与生理效益完全消失。
