去卵巢大鼠Ru 486与垂体及子宫内膜孕激素受体结合的比较

经雌激素诱发的去卵巢大鼠在肌肉注射不同量的 Ru486(0.1mg/kg—2mg/kg)之后,垂体及子宫内膜的胞液游离孕激素受体结合位点随着 Ru486注射量的升高而逐步下降。注射 Ru486 2mg/kg 30min 后,此两组织中孕激素受体的结合位点就明显降低,2h 降到最低点,3h 开始恢复。以上实验说明 Ru486进入机体即可分别占领垂体及子宫内膜的孕激素受体的结合位点。然而 Ru486对此二组织的孕激素受体的结合作用并不完全相同,似乎子宫孕激素受体更易为 Ru486所占位,而解离也快。     

兔输卵管峡部平滑肌阵发性活动与卵巢激素的关系

本文记录了不同卵巢激素状态下兔离体输卵管峡部平滑肌收缩活动及肌电变化。成年动情兔和排卵兔输卵管峡部活动强,呈现阵发性收缩或放电;幼兔及切除卵巢成年兔峡部活动弱,无典型的阵发收缩,若给这种兔补充雌激素阵发性收缩又可出现。结果表明峡部平滑肌阵发性活动与卵巢激素有密切关系,雌激素在维持阵发性活动中起着相当重要的作用。     

不同剂量的抗孕-53和18-甲基炔诺酮对大鼠垂体机能反应性影响的比较

为了研究甾体避孕药对垂体生殖激素的影响,本实验以动情前期大鼠受二次静脉注射GnRH诱发的LH激发效应(priming effect)为模型,观察经肌肉注射不同类型、不同剂量的避孕药(抗孕-53或18-甲基炔诺酮)后垂体对GnRH的敏感性反应。抗孕-53的剂量为3,1.5,0.75,0.375和0.19mg;l8-甲基炔诺酮的剂量为4,1和0.5mg,各溶于0.5ml茶油;对照组为0.5ml茶油。实验结果表明,不同剂量的抗孕-53均促进血浆LH浓度升高,其中以3mg组的反应最显著,与对照组比较P<0.01。不同剂量的18-甲基炔诺酮对垂体敏感性均有显著的抑制作用,使血浆LH浓度降低(P<0.01)。大鼠经肌肉注射乙炔雌二醇21μg和10.5μg后,其垂体对GnRH的反应也有促进作用,但不能完全模拟抗孕-53的效应。上述结果表明,不同类型的甾体避孕药能增加或降低大鼠垂体对GnRH的敏感性。

The relevance of tissue thiol histochemistry to diagnostic hematopathology

Expression analyses suggest that alterations of the antioxidant state of some diffuse large B-cell lymphomas can assist prognosis; reversibly oxidized thiols may serve as a surrogate marker for identifying such cases. Little is known about the distribution of free thiols and reversibly oxidized thiols in human tissues. We developed a staining technique that enables visualization of tissue thiols in situ using bright field microscopy and validated it using gastrointestinal tissue specimens. We used our thiol staining technique to assess benign tonsillectomy and diffuse large B-cell lymphoma specimens. The gastrointestinal series revealed the presence of free thiols within epithelial cells and cells of the lamina propria. Staining for reversibly oxidized thiols was robust in gastric foveolar cells, intestinal goblet cells and the mucus they produce. Tonsillectomy specimens exhibited diffuse presence of free thiols. Staining for reversibly oxidized thiols was confined to germinal center macrophages and sinus histiocytes. Among the diffuse large B-cell lymphoma specimens, we observed strong staining for free thiols within malignant cells. By contrast to benign B-cells, the malignant cells demonstrated pronounced and diffuse staining for reversibly oxidized thiols. We demonstrated intrinsic differences between benign and malignant cells.     

武昌东湖地区摇蚊科昆虫的研究

据目前所知,1940年有关作者曾对采自我国云南、西藏和台湾等地的摇蚊科昆虫先后报导过69种10,11,13,15,16,18,19,其中台湾的种类几乎占到90%。本文的报导系于1963年和1964年作者以灯诱和昆虫网捕捉两种方法,在武昌东湖地区收到大量的摇蚊科昆虫的标本,共鉴定出37种,分别隶属于3亚科16属。其中摇蚊亚科的3个属即雕翅摇蚊属(Glyptotendipes),沼摇蚊属(Limnochironomus)和劳特摇蚊属(Lanterbor-niella)在我国为首次记录;在37种之中,除6种已报导见于我国台湾外,有31种在我国为首次记录。通过标本数量的分析,作者认为有9种应为东湖地区的优势种类。       

A new monotypic genus of a parmulariaceous dictyosporous ascomycetes from Taiwan

A new monotypic ascomycete genus, Dictyocyclns gen. nov. with D. hydrangeae sp. nov. as its type, is described and illustrated. It is placed in the family Parmulariaceae and it is the second genus in that family with dictyoseptate ascospores. It is compared with Aldonata the only other member of the family with similar ascospores.
