The endermic LD50 to rat and mouse were 926 mg/Kg and 1210 mg/Kg respectively. The results of subscute toxicity test in rats showed that the content of blood urea nitrogen in exposure groups was higher than that in control group, the histopathological changes of testis observed in exposure groups were obvious. Mutagenic tests including bacillus subtilis DNA rec-assay, micronucleus ...

其大、小鼠经皮LD_(50)分别为926mg/kg和1210mg/kg；大鼠90天经皮染毒，试验组BUN含量高于对照组，光镜下，试验组睾丸的组织学结构有明显改变；枯草杆菌DNA重组试验、小鼠骨髓多染红细胞微核试验和小鼠睾丸染色体畸变分析试验均获得阳性结果。

A PCR product was amplified using RT-PCR method from total RNA from the abdomens of R strain using the degerated primer. The PCR product was purificated and cloned. The plasmid is pBluescript Ⅱ KS. Recombined plasmid DNA was identified by endoenzyme. The results indicated there were different P450 genes in the PCR product.

运用这对简并引物首次从德国小蠊抗拟除虫菊酯的品系R中扩增出的特异性的DNA片段，经纯化、连接和转化，重组至pBS质粒，筛选阳性克隆，提取重组质粒的DNA，并经初步的酶切鉴定，发现存在着不同的CYP4基因。

Methods of stem cell transplantation for acute myocardial infarction included direct epicardium and endocardium injection, intravenous infusion and coronary catheter injection, of which coronary catheter injection was a prospective approach that was direct and with small wound.

干细胞移植治疗急性心肌梗死的方法主要有直接心外膜、心内膜注射、静脉输注和经冠状动脉导管注射4种形式，其中经冠状动脉注射较为直接，创伤小，可能是最有前途的移植途径。

Result Based on directly regenerated plant of in vitro plant of Xinjiang cotton, the cotton epicotyl treated by pre-culture for 3-5 d was immersed in bacteria for 15 min and co-cultured for 2 d. Cephalothin at 100 mg/L was used to inhibit bacteria after 50 mg/L kan selection. And the combination of cytokinin with relatively high content and auxin with low content was used in its directly budding culture to obtain resistant seedlings.

结果］在新疆棉花离体培养植株直接再生植株基础上，经3~5d预培养处理过的棉花上胚轴，在浸菌15 min共培养2 d后，经50 mg/L kan筛选，用1000 mg/L头孢霉素抑菌，并用相对高含量细胞分裂素和低含量生长素的组合对其进行直接出芽培养，从而获得抗性小苗。
