Castor seeds were degreased with 3 kinds of solvents including petroleum ether, aether and methylene chloride, and ricins were extracted from the defatted castor cake with acetic acid solution. And the rat-killing activities of 3 kinds of ricins were compared in the rat-killing activity test.

方法］用石油醚、乙醚、二氯甲烷3种溶剂分别对蓖麻粗籽进行脱脂后，用醋酸水溶液从脱脂的蓖麻饼中提取蓖麻毒蛋白，通过杀鼠活性试验比较3种蓖麻粗毒蛋白的杀鼠活性。

There are distinctdifferences in the distribution and metabolism in the rat tissues after ivadministration of the two epimers of GL. After iv administration,α-GL istarget to the liver, and can be efficiently converted to more glycyrrheticacid thanβ-GL, and it nearly has no accumulation in the tissues.The distribution ofβ-GL in rat tissues appears to be wide throughout thebody, and its metabolism is slower than that ofα-GL to accumulating insome tissues.

结果显示α-GL与β-GL在大鼠体内的组织分布存在显著性差异，大鼠尾静脉注射α-GL后在体内呈肝分布特异性，转化成甘草次酸的速率高于β-GL，无组织蓄积；而β-GL在体内分布广泛，代谢较慢，有蓄积的可能。

The genomes of two group neurons were extracted. Integration of rAAV-hBDNF in rat hippocampal neurons was detected by Southern blot using mh- BDNF and Neo probe labeled by digoxin. The results displayed the genome of rAAV-hBDNF had existed in the rat hippocampal neurons in form of episome.

提取实验组和对照组培养海马神经元基因组，用地高辛标记的mhBD-NF探针和Neo探针分别进行Southern杂交，结果表明，rAAV-hBDNF基因组以附加体形式存在于海马神经元，而并非整合形式存在。

objective to investigate whether hypoxia preconditioning exist in adipose tissue,and construct the hypoxemic model of adipose tissue.methods after injected different density cocl2 to rat's subcutaneously of groin,use immunohistochemical method detect hif-1α protein,and use rt-pcr detect hif-1α mrna.results after injected different density cocl2,the adipose tissue of rat's groin express different degree of hif-1αprotein and hif-1αmrna.,and reach the peak when the density is 20-40 mg/kg and the time is 3 h.conclusion hypoxia preconditioning exist in adipose tissue,and the effect of preconditioning is most evidence when the density is 20-40 mg/kg and the time is 3 h.

目的 探讨脂肪组织中是否存在缺氧预适应现象，构建cocl2致缺氧的缺氧模型。方法不同浓度的cocl2大鼠腹股沟区皮下层浸润注射，分别用免疫组织化学法和rt-pcr法检测该区脂肪hif-1α蛋白和hif-1α mrna的表达情况。结果用不同浓度的cocl2行化学缺氧后在不同时间点观察有不同程度的hif-1α蛋白和hif-1α mrna表达，其中，在浓度为20～40 mg/kg，时间为3 h时脂肪组织中hif-1α表达达高峰。结论脂肪组织存在缺氧预适应现象；cocl2的浓度选择20～40 mg/kg，时间选择3 h时缺氧预适应效果较佳。
