LDL??C, ALT and AST in serum, and the even plasma TG and CHOL contents.

、LDL？？C、ALT、AST水平及肝组织匀浆TG、CHOL的含量。

A polyclonal antibody against vitellin was prepared in male rabbits and the specific antibody against vitellin was made through absorbtion by male worm homogenate. After purification, HRP was used to mark antibody, then ELISA was set up to detect vitellin content in the Chrysopa septempunctata fat-body, hemolymph and ovary.

提取了大草蛉的卵黄蛋白，免疫家兔，并将所得抗血清经雄虫匀浆液吸收，获得抗卵黄蛋白的特异抗体，经纯化后，用辣根过氧化物酶标记抗体，建立了ELISA法测定大草蛉脂肪体、血淋巴和卵巢中卵黄蛋白含量的方法。

The pharmacokinetics of Hup A in blood and eerebrospinal fluid after intranasal, intravenous and intragastric adminstration to rats was studied using cisternal cannulation for serial CSF sampling and femoral artery cannulation for serial blood sampling.

以市售片剂和注射液为对照，用小脑延髓池插管法采集脑脊液，股动脉插管取血，测定其在大鼠脑脊液和血中药物动力学参数；用组织匀浆法，测定其在大鼠脑组织中的分布；用Morris水迷宫法、跳台法和避暗法试验其对大鼠和小鼠模型的药效。

Colorimetric method was used to determine PGE and MDA contents.

采用比色法分别测定了大鼠血浆中PGE含量及肝脏匀浆中MDA的含量。

After varied survival periods, the model mice were sacrificed to get the specimens of SN fixed, embedded and coronally sectioned continuously. The microsections were processed by immunohistochemistry to label the DA neurons and Calbindin D28k-containing neurons with the antibodies against tyrosine hydroxylase and CR respectively. The labeled cells were counted under microscope and analyzed statistically.
