The unoperated sides of the treated animals also served as controls. Six normal rats were treated as normal control group. Three different siRNA plasmid solution containing RC2-Ⅰ, MAFbx-Ⅱ, CON (50μl , 0.8μg/μl)was injected and transfected by electroporation as methods mentioned above, respectively. The changes of RC2 and MAFbx mRNA levels and RC2 protein levels after 3 days were determined by real-time quantitative PCR and Western blot, respectively. On postoperative 2, 3 and 4 weeks, the rate of wet muscle weight preservation, mean diameter of muscle fiber and mean cross-section area of muscle fiber and muscle protein content were checked and then compared between group CON and group RC2 or group MAFbx, respectively. The differences between groups were analyzed by one-way ANOVA. Ultrastructural changes of muscle fiber were observed at 2, 3, 4 weeks postoperation.Results GFP plasmid was efficiently deliverd into muscle by electroporation and robust GFP expression in muscle could be observed more than three weeks. Histology shows that injected plasmid DNA diffuses extensively in muscle tissue.

The toxicity of cryoprotectans increased as the concentration of its increased.3, the survival rate of embryos microinjected with 6M PM was 25.07±1.57% after being coolled in -20℃ for 10 minutes by programmed cooling method, whenas ,the survival rate of controls dealt with five steps balance method was 20.88±2.84%, which indicated that the chilling sensitivity of embryos with microinjection decreased.

而任何一种抗冻剂均随着浓度的增加其毒性随之增加。3、另外，在冷敏感实验中，显微注射6M的PM的胚胎胚胎，应用程序化法处理，以2℃/min的速率降至-20℃，平衡10min后解冻处理，发现注射PM的胚胎低温处理后成活率为25.07±1.57%，而6M的PM五步平衡法同步处理的对照组胚胎成活率为20.88±2.84%，说明显微注射的胚胎冷敏感性一定降低。

We conclude that KB-R7843 has protective effects on contrast media-induced nephrotoxicity. The protective role of KB-R7943 may be related to its positive effects on renal hemadynamics through inhibiting the increase of ET-1 and TXA2 induced by contrast media in the environment of hypercholesterolemia and its cytoprotective influence on renal cells.
