慢性肺心病红细胞变形性与红细胞膜流动性变化（附17例病例分析）

用荧光偏振法测定17例慢性肺心病急性发作期患者及17名健康人红细胞膜流动性,用微孔泸膜法测定其中10例红细胞变形性。结果,肺心病患者及正常人红细胞膜微粘度分别为4.64±1.56及3.51±1.05η(p<0.05);红细胞滤速分别为384±136及233±97(p<0.01)。红细胞滤速与红细胞膜粘度间呈明显正相关(r=0.802,p<0.01)。结果提示,肺心病患者红细胞膜流动性下降可能对红细胞变形性下降起一定作用。     

Deletion of the carboxy-terminus of herpes simplex virus type 1 (HSV-1) glycoprotein B does not affect oligomerization,heparin-binding activity,or its ability to protect against HSV challenge

Summary A recombinant vaccinia virus designated VgBt which expresses a truncated secreted herpes simplex virus gB (gBt) was constructed and compared to V11gB, a vaccinia recombinant previously studied which expresses gB exclusively on the surface of infected cells. Indirect immunofluorescence assay (IFA) revealed that gBt was strongly associated with the surface of infected cells despite being released slowly into the cell culture medium. Both gB and gBt existed as oligomers, and both membrane bound and secreted forms of gBt exhibited heparin-binding activity. In protection studies VgBt and V11gB conferred equivalent protection against both homologous (HSV-1) and heterologous (HSV-2) challenge with HSV.     

滤膜荧光法检测大肠菌群及其与标准滤膜法的比较

目的：用滤膜荧光法检测大肠菌群，并将该法与标准滤膜法进行比较。方法：将菌种于肉汤培养基中培养至对数生长期，稀释，用微孔滤膜过滤，将滤膜置于含ＭＵＧＡＬ的培养液的衬垫上，置３７℃培养，在不同时间取出观察，并作荧光斑点扫描。结果：经实验室模拟水样和列车餐车水样检验，滤膜荧光法和标准滤膜法结果无差别。结论：滤膜荧光法与标准滤膜法相比具有快速、适用于现场检测的特点

中国中原地区33555名妇女妇科疾病发生情况与五种因素关系的调查报告

自１９９２年３月至１９９４年５月，对中原地区４个省２０多个县（市）近２００个单位３３５５５名２０～７５岁的已婚妇女，进行妇科疾病发生情况与年龄、职业、文化、月经、孕产等五种因素关系的调查分析。在３３５５５名妇女中，患病者２２３７０人，总患病率为６６．６７％，查出妇科疾病４２种，计７６９７４例次。结果证明：以２５～３５岁年龄组发病率最高，其中以内生殖器炎症为主；职业以经商者发病率高，特别是性病患者高于其他职业者二倍以上；文化程度以小学、初中者发病率高，尤其宫颈炎更明显；月经情况：随着经前期紧张综合征的加重，更年期综合征发病率增高；孕产次数越多，患病率越高。本次调查未发现宫颈癌，进一步证明我国对妇女保健工作的关心和重视。     

Results of the TeachWell worksite wellness program.

OBJECTIVE: This study examined whether providing a school-based teacher wellness program enhances the impact of a health curriculum on student outcomes and improves cognitive, behavioral, and physiological outcomes among participating teachers. METHODS: Thirty-two elementary schools were randomly assigned to experimental or comparison conditions. Comparison group schools received the Gimme-5 program, a curriculum designed to increase fourth and fifty graders' consumption of fruits and vegetables. Experimental schools received Gimme-5 and the teacher wellness program, which included 54 workshops over 2 years, along with several schoolwide health activities. Physiological, behavioral, and cognitive outcomes were assessed in teachers and students. RESULTS: There was no evidence that the intervention favorably modified any student or teacher end points; nor did intervention teachers deliver the Gimme-5 program with greater fidelity than comparison teachers. CONCLUSION: Confidence in the null results is bolstered by the randomized design, baseline sample equivalence, appropriate mixed-model analyses, and lack of selective or differential attrition. Insufficient participation in the wellness program appears a likely explanation for the lack of teacher and student effects. Factors specific to the school setting and intervention may have diminished participation and, thus, intervention effects.     

一期动静脉转流与并加压破坏深静脉瓣对比的实验研究

目的:改进一期动静脉转流术的疗效。方法:10只狗双后肢,随机选择一侧后肢行一期动静脉转流,另一侧行一期动静脉转流加水压破坏深静脉瓣。术后30天通过动脉造影进行对比研究。结果:后者能更有效地加速远段深静脉瓣的破坏,使动脉血逆行更远,同时形成更为丰富的侧枝循环,而不会增加肢体肿胀和深静脉血栓的机会。结论:一期动静脉转流加水压破坏深静脉瓣可能是治疗严重肢体缺血更为有效的方法。

大鼠实验性急性肝损伤抗凝血酶Ⅲ的测定及意义

通过用D-氨基半乳糖(D-GalN)造成大鼠不同程度的急性肝损伤,测定损伤后24h、48h血清AT-Ⅲ水平的变化,并与前白蛋白、谷丙转氨酶、谷草转氨酶相比较。结果表明,大鼠实验性急性肝损伤24h 后AT-Ⅲ水平即开始下降,肝细胞损伤越严重,则AT-Ⅲ水平越低,下降幅度与肝细胞损伤的严重程度相关。在反映肝细胞损伤程度上优于转氨酶的测定,比前白蛋白敏感。
