黑鼠

Results ①Compared to sham group, ISH and IHC of rat hypothalamic CRHshow positive cells numbers increase, positive areas enlarge and average gray scaledecreases, which reveals the expression of hypothalamic CRH neurons enhances afterPX;②The enhancement of ISH and IHC of hypothalamic CRH in PX rats aftermelatonin supplementation dose-dependently recovers, but it can't return to be normaleither in high dose group or in low dose group and either at 4th week or at 8th week;③IHC of CRH in median eminence of neurohypophysis shows positive areas enlargeand average gray scale decreases, which reveals the releasing of CRH fromhypothalamic CRH neurons increases;④ELISA of CRH in serum shows thedifferences of CRH concentrations among all groups are not significant, which indicates PX and melatonin supplementation have no significant effect on CRH levels.

结果： ①松果体摘除后大鼠下丘脑室旁核CRH 原位杂交和免疫组化的结果与假手术对照组相比均显示阳性细胞数增多、阳性面积增加、平均灰度降低，提示松果体摘除后下丘脑CRH 神经元的表达增强；②松果体摘除大鼠补充褪黑素后，下丘脑CRH 原位杂交和免疫组化染色增强呈剂量依赖性恢复，不过不论是低剂量组还是高剂量组，也不论是术后4 周还是术后8周，均不能恢复至正常；③松果体摘除后神经垂体正中隆起CRH 免疫组化结果显示阳性面积增加、平均灰度降低，提示下丘脑CRH 神经元释放CRH 增加；④ELISA 法检测血清CRH结果示各组血清CRH 浓度差异没有显著性，表明松果体摘除及补充褪黑素对血清CRH 水平没有显著影响。

Experiments show that the black rat has been eating, if the lack of folic acid, pantothenic acid, vitamins and other food, rat hair will become gray.

实验证明，黑鼠如果一直进食缺乏叶酸、泛酸、维生素等的食物，鼠毛便会变成灰白色。

Results There were negative expressions of α-MSH in both the hair follicle melanocytes of the Kunming white-mouse and the scarfskin of the FMN white-guinea pig; while there was positive expression in both the hair follicle melanocytes of the C57BL/6J black-mouse and the scarfskin of the HARTLY brown yellow-guinea pig.

结果］α-MSH在白色昆明小鼠毛囊及白色FMN豚鼠表皮中呈阴性表达，在C57BL/6J小黑鼠毛囊黑素细胞及棕黄色HARTLY豚鼠表皮黑素细胞中呈阳性表达。

The biological characteristics and toxicity of Russula subnigricans Hongo was studied for the first time from ecology and morphologic characteristics and histology, the orthogonal experiment of the optimum culture condition, the analysis of components, apoptosis of the cells from little white rat liver and kidney induced by extract of Russula Subnigricans Hongo,to the histopathologic changes observation of little white rat liver and kidney through ecological observation, light microscopy and scanning electron microscopy, reversed-phase high performance liquid chromatography, agarose gel electrophoresis, transmission electron micioscopy.

利用菌种分离技术、光镜技术、电镜技术、高效液相色谱技术、毒理实验技术、电泳方法等对亚稀褶黑菇的生物学特性和毒性机理进行了研究，主要包括以下内容：亚稀褶黑菇的生态学和组织学研究、菌种分离培养、扫描电镜观察、成分分析、粗毒液诱导小自鼠肝肾细胞凋亡，小白鼠中毒后肝肾细胞透射电镜观察，研究结果如下： 1。

The two white-skin animals are suit for research of zoopery of increased-pigment disease, while the other two are suit for research of zoopery of reduced-pigment disease; and α-MSH is one of the most important indicators in the research of zoopery with pigment disease.

结论］白色昆明小鼠及白色FMN豚鼠适宜做色素增加动物实验研究，C57BL/6J小黑鼠及棕黄色HARTLY豚鼠适宜做色素减退动物实验研究；α-MSH可做为观测色素代谢障碍性疾病动物实验研究的一个重要指标。

Cats captain ran past, the black rat, said:"Stop!......"

猫队长跑过去，黑鼠说：&停！……&

Cats continue to walk, they saw the black rat.

猫继续走，又看到了小黑鼠。

Renaissance artists sometimes used a black rat to symbolize night and a white one to symbolize day.

文艺复兴时期的艺术家有时用黑鼠象征夜晚，白色象征之一一天。

But the cat who does not listen, did not expect that at the foot of a hole, and then the cat-hole leader to go on falling, black rat smile ran away.

但是猫们不听，没想到脚下是一个洞，然后猫队长就掉下洞去，小黑鼠笑了笑就跑了。
