And he said that between the rats and the snakes and the grindstone there warn't no room in bed for him, skasely; and when there was, a body couldn't sleep, it was so lively, and it was always lively, he said, because THEY never all slept at one time, but took turn about, so when the snakes was asleep the rats was on deck, and when the rats turned in the snakes come on watch, so he always had one gang under him, in his way, and t'other gang having a circus over him, and if he got up to hunt a new place the spiders would take a chance at him as he crossed over.

他还说，他这样在在耗子、蛇和磨刀石的中间，在他那张床上，他简直没有容身之地了。他说，即便是可以容身的时候吧，他也睡不成觉，因为在那个时候，这儿可闹得欢呢。而且这里老是这么闹得欢，因为这些东西从来不是在同一个时候入睡的，而是轮流着睡的。蛇睡的时候，耗子出来上班。耗子睡了，蛇就出来上班。因此，这么一来，他身子下面总有一群东西，而这时另一群则在他身上开演其马戏。要是他起身寻觅一处新的地方，蜘蛛就会在他跨过去的时候，找个机会蜇他一下。

The inducible nitric oxide synthase is obviously expressed in speen of rats under the predator stress, suggesting important function for iNOS in speen physiology. However, the expression and subcellular localization for NOS in speen development and differentiation are largely unknown. In the present study, the changes in iNOS activity in spleen of rats under predator stress were studied to explore the role of iNOS in the decreased immunoactivity of the stressed rats. The changes in iNOS were observed with immunobistochemical method, and the contents of NOS and NO in spleen with biochemical method.

objective:to investigate the influence of soybean isoflavones on the antioxidative effect and improving the ability of study and memory in climacteric rats.methods:forty-eight female sd climacteric rats were randomly divided into 4 groups with one control group and the other low,medium and high dose groups,which were given soybean isoflavones 0 mg/kg.bw,42 mg/kg.bw,83 mg/kg.bw and 249 mg/kg.bw by superalimentation daily for 60 days respectively.the levels of sod,gsh-px and mda in serum were measured,and the ability of study and memory in each group was deterimined by adopting the law of diving platform.results:the content of serum mda in medium and high dose groups was lower than that in control group.the activity of serum gsh-px im medium and high dose groups was significantly increased,so was the activity of serum sod in low,medium and high dose groups.conclusion:soybean isoflavones do have the obvious effect of antioxidation,and improve the ability of study and memory effectively in female sd climacteric rats.
