对实验性兔瘟病例的血清及组织中脂质过氧化物的分析

本实验以TBA比色测定了兔瘟血清、肝、肾及肺组织中脂质过氧化物(LPO)的浓度。结果表明兔瘟病毒可明显(P<0.01)增加家兔肝、肾及肺脏组织中LPO的水平。对照组与实验组LPO的平均水平分别为:肝110.27与521.54n mol(MDA)/g;肾111.47与199.51n mol(MDA)/g;肺82.96与148.00n mol(MDA)/g。家兔血清中LPO的水平在攻毒前后没有明显改变,分别为5.01n mol(MDA)/ml和5.30n mol(MDA)/ml。关键词:脂质过氧化物,兔瘟。     

新型染发剂的制备与应用

FK506在同种异体兔角膜缘移植中的应用

目的：研究FK506对同种异体兔角膜缘移植术后免疫排斥反应的抑制效应。方法：建立48只新西兰白兔角膜缘于干细胞缺陷症动物模型，随机分成FK506治疗组、环孢霉素A治疗组和非治疗组，同种异体角膜缘移植术后分别给予质量分类为0．5％FK506滴眼液、1％环孢霉素A滴眼液和生理盐水点眼，用药4周。术后持续观察10周，以角膜缘植片水种、混浊程度、排斥反应发生时间、角膜新生血管和假性胬肉作为眼表评估指标。结果：观察期内，FK506组上皮排斥反应发生率、移植排斥指数均低于环孢霉素A组，差异有显著性（P＜0．05）；而两组成新生血管和假性胬肉指数方面，无显著性差异（P＞0．05）。结论：同种异体角膜缘移植术后早期应用FK506眼液点眼可以抑制排斥反应发生。

Molecular genetic basis for the rhino mouse from Chinese KM subcolony

Both the rhino mouse and hairless mouse resulted from hairless gene mutation, but they show different phenotypes of skin physiology. The rhino mouse has more similar histological characters to human papular alopecia.Therefore rhino mouse is a good experimental animal model for human papular alopecia. This study reports a hairless mouse named rhino KIZ, arose from KM colony in Kunming Institue of Zoology, by systematic studies on morphology,skin histopathology, gene sequence, pedigree and protein domain analysis. The results demonstrate that a C-to-T transition in exon 11 of hr gene (The mutant gene has been applied for a Chinese patent (patent No. 03135280)) results in the rhino KIZ. The rhino KIZ with clear genetic mechanism will be a useful animal model.     

Serial nuclear transfer improves the development of interspecies reconstructed giant panda (Aluropoda melanoleuca) embryos

Interspecies somatic nuclear transfer (NT) may provide a new approach for preservation of the endangered rare species. Previous interspecies cloning studies have shown that a nucleus from a quiescent somatic cell supports early development of reconstructed embryos in the ooplasm from another species. In this study, we transferred nonquiescent somatic cells from a giant panda into the perivitelline space of the enucleated rabbit oocytes. After electrofusion (at the rate of 71.6%) and electrical activation, 4.2% of the panda-rabbit reconstructed embryos developed to blastocyst in vitro. For improving the development rate of reconstructed embryos, we used serial NT in this study, i.e. blastomeres from reconstructed morulae were transferred into the perivitelline space of the enucleated rabbit oocytes. The fusion rates in the groups of serial I, serial II and serial III were 79.5%, 84.1% and 78.0%, respectively, having no difference with that of somatic group. And the blastocyst rates in serial NT groups were 19.4%, 13.5% and 10.3%, respectively, which are significantly higher than that in somatic NT group. These results indicate that the nuclei from nonquiescent somatic cells can support early development of reconstructed embryos and serial NT can improve the development rate of interspecies reconstructed embryos.
