玉津酒治疗大鼠佐剂性关节炎及免疫学的观察

目的:探讨玉津药酒对大鼠佐剂性关节炎(AA)治疗效果及免疫学改变.方法:以完全弗氏佐剂诱导大鼠AA模型,灌胃服用玉津酒,观察AA大鼠病症改善情况及对免疫功能的影响.结果:在诱导AA模型前灌胃服用玉津酒,可推迟大鼠AA的发病时间,降低发病率,减轻关节炎症状;在大鼠发生AA后服用玉津酒,可明显抑制关节炎症程度;服用玉津酒可抑制AA大鼠T、B淋巴细胞增殖反应及IL-1活性.结论:玉津酒是通过机体免疫调节达到对AA的预防和治疗作用.

正常人尿中单羟酚类物质含量的测定研究

目的：确定正常人尿中单羟酚衍生物（ＭＨＰ）含量范围。方法：采用可见分光光度法,定量测定１８～６０岁各类正常人及ＨＢｓＡｇ阳性携带尿液中单羟酚类物质。结果：ＭＨＰ含量与年龄、性别有一定的,１９９４例健康人尿中ＭＨＰ含量为正态分布,第９５百分位数的ＯＤ值上限为０．３,对应酷氨酸含量是２．４６ｍｍｏｌ／Ｌ,而ＨＢｓＡｇ阳性携带者尿液ＭＨＰ与正常人无显著性差异。结论：此实验结果在运用ＭＨＰ进行肿瘤筛查时,     

支气管肺炎患儿血清IL-6水平变化及临床意义

采用放免法检测了42例支气管肺炎和25例对照组小儿血清白细胞介素-6(IL-6)水平,结果显示肺炎患儿血清IL-6水平较对照组显著升高(P<0.01);重症肺炎与轻症肺炎患儿血清IL-6水平相比较有显著差异(P<0.001),病情越重,其水平也越高;IL-6水平与末梢血白细胞总数升高程度有一定相关,呈正比例关系。提示IL-6是反映肺炎感染严重程度的良好指标。

Scanning laser ophthalmoscope imaging of fluorescein-labelled blood cells

Purpose: To demonstrate the feasibility of a technique for the visualization by scanning laser ophthalmoscope (SLO) of fluores cein-labelled autologous leukocytes and platelets in retinal vessels. Method: Individual blood samples from rats and rabbits were centrifuged to isolate platelets and leukocytes, then passively labelled with fluorescein and reinjected into the same animal. An SLO was used to visualize and record cell displacement in the retinal circulation. Labelled platelets were analysed by flow cytometry. Results: By SLO, platelets appeared as a heterogeneous particle flow, and individual leukocytes appearing as brighter spots could easily be traced. Flow cytometry showed that after labelling platelets were well individualized and their size was slightly increased. Conclusion: Circulating blood cells can be visualized in retinal vessels by a simple method consisting of passive labelling of autologous platelets and leukocytes by fluorescein. No platelet toxicity was detected. This method could be applied to the study of blood cell movement in human retinal vascular diseases.Proprietary interest category: N     

长效避孕栓剂对家兔的抗生育作用

目的和方法:是观察NP-9长效避孕栓(100mg/栓)于家兔阴道给药后15分钟和3.5小时的抗生育作用和连续7天给药的阴道刺激试验。结果:长效避孕栓无论在给药15分钟还是3.5小时交配避孕率均为100％。而生理盐水和赋型剂对照组避孕率分别为0％和40％。家兔阴道刺激试验结果表明:该栓剂阴道刺激炎症总分值为6.9,在可接受范围内。
