The study of mechanism of its anti-inflammationThis experiment shows that NTL can inhibit the edema of hind paw induced by fresh egg white in adrenalectomized rat, reduce the weight of thymus in rat, increase the content of hepatic glycogen ,but decrease eosinophil of mice through experimentalstudy of effect of NTL on edema of hind paw induced by fresh eggwhite in adrenalectomized rat, weight of thymus in rat, content ofhepatic glycogen and eosinophil of mice. The results indicate that NTL has the analogous function to cortin.

抗炎机理研究通过虎斑游蛇对去肾上腺大鼠蛋清性足跖肿胀、对大鼠胸腺重量和对小鼠肝糖原含量及对小鼠嗜酸性粒细胞数量影响的实验研究，表明虎斑游蛇能够抑制去肾上腺大鼠蛋清性足跖肿胀，使小鼠胸腺的重量减轻，增加小鼠肝糖原的含量而减少嗜酸性粒细胞的数量，提示虎斑游蛇具有肾上腺皮质激素样作用。

Trichogramma showed high control efficacy on cotton bollworm eggs after three times of release both in the second and in the third generation bollworm periods. The parasitism on the second and third generation bollworm eggs were 66.0%-70.7% and 76.0%-81.2%, respectively, which were significantly higher than that in the control (second generation: 7.0%-12.3%, third generation: 5.2%-7.4%). And the injury rate of cotton buds and bolls in the second and third generation bollworm were 2.2% and 3.1%, respectively, which were significantly lower than that in the control (second generation:8.5%, third generation: 20.9%). In the second generation bollworm period, number of bollworm eggs or larvae in the Trichogramma released cotton field did not differ to that in the chemically controlled field. But in the third generation, there were significantly less bollworm eggs and larvae in the Trichogramma released cotton field. There were more predators in the Trichogramma released cotton field. These results indicated that cotton boll worm in the transgenic insect-resistant cotton field can he effectively controlled by mass-releasing of T.

To the deer it is a reminder of the way of all flesh, to the pine a forecast of midnight scuffles and of blood upon the snow, to the coyote a promise of gleanings to come, to the cowman a threat of red ink at the bank, to the hunter a challenge of fang against bullet.

这吼声使鹿想起了它失去了的亲人，对松树来说它是午夜的混战和白雪上的鲜血，对山狗则意味着一个拾人牙慧的机会，对牧场主则意味着银行赤字的威胁，而对猎人，则意味着尖牙和子弹的较量。

Adding N, P could improve cucumber root activity, increased the absorptionof N, P and Mg, decreased that of K; Adding N improved the contents of Ca,Fe, Mn and Zn in leaves, and adding P accelerated absorption of cucumberroot to Fe. Adding K decreased the contents of N, P in leaves, but increased K,Fe content, contents of Ca, Mn and Zn decreased at the same time.4. Adding the rates and ratio of N, P, and K increased the activity of SOD incucumber leaves and root. The changes of POD activity were complex, maybeP played the more important role.
