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,     

胃粘膜内pH值测定在危重病人中的预警价值

目的 :观察在危重病患者中反映组织水平氧代谢的胃粘膜内 p Hi,与反映全身氧代谢的指标间的关系以及胃粘膜内p Hi的预警价值。方法 :用胃张力计测定危重病患者入科即刻及治疗 2 4h后胃粘膜内 p Hi,并测定 p Ha ,Pa O2 / Fi O2 ,行 APACHE 评分。结果 :死亡组入科即刻 p Hi( 7.13 3± 0 .3 74)较存活组 ( 7.3 89± 0 .0 62 )显著降低 ( P<0 .0 1) ,治疗 2 4小时后胃粘膜内 p Hi死亡组( 6.911± 0 .496)较存活组 ( 7.43 4± 0 .0 5 1)降低更显著 ( P<0 .0 0 1) ;入科即刻 p Hi≤ 7.3 2的患者病死率为 75 .0 %,治疗 2 4h后胃粘膜内 p Hi≤ 7.3 2的患者病死率为 88.9%。结论 :作为局部组织氧合指标的 p Hi在常规的全身氧代谢指标未改变之前就发生了明显的变化 ;p Hi的降低与病死率有明显的相关性。     

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。

吗啡依赖动物戒断后的焦虑情绪变化

本文采用高架十字迷宫模型和Vogel's饮水冲突模型观察吗啡依赖动物自然戒断后18、24、48、72、96、120h的焦虑情绪 ,结果表明吗啡依赖动物自然戒断后48h时的焦虑症状在两种模型上都最为明显 ,丁螺环酮可明显缓解吗啡所致的焦虑情绪。提示高架十字迷宫模型和Vogel's饮水冲突模型可较为客观和准确地反映吗啡所致焦虑情绪。     

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     

颈椎不同位置时椎管矢状径及截面积的解剖研究

为观察坐位颈椎不同位置时椎管内结构的变化,解剖颈椎标本８具。用灌石蜡的方法测量颈椎矢状径及截面积的变化。结果：颈椎轻度屈曲时,椎间盘、黄韧带、椎板、硬膜、脊髓的形态与位置发生变化,但对椎管容积影响不大,中立位和自然屈颈位时椎管矢状径和椎管截面积两者均无明显差异（ｐ＞０．０５）。提示：颈椎后路椎板成形椎管扩大手术时,坐位是值得推荐的一种体位。     

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。
