应用羧化胶乳凝集试验诊断人、畜布鲁氏菌病的研究

应用以化学交联法制备的布鲁氏菌１６Ｍ抗原－羧化胶乳制剂的羧化胶乳凝集试验（ＬＡＴ）、试管凝集试验（ＳＡＴ）、虎红平板凝集试验（ＲＢＰＴ）以及酶联免疫吸附试验（ＥＬＩＳＡ）、半胱氨酸凝集试验（ＣＹＴ），对在四省布鲁氏菌病疫区收集的部分人、畜血清中布氏菌抗体进行对比检测。结果表明，ＬＡＴ较之ＲＢＰＴ具有更高的特异性；与ＳＡＴ相比，无论阳性或阴性符合率均较一致。另外，ＬＡＴ可检测血清中ＩｇＧ、ＩｇＭ两类布氏菌特异性抗体。因而本试验对人、畜布病的诊断具有特异、敏感和简便的优点，更宜在基层推广应用。

巢式聚合酶链反应检测脑脊液中单纯疱疹病毒DNA

应用巢式聚合酶链反应(PCR)检测患者脑脊液(CSF)中单纯疱疹病毒1型(HSV-1)DNA。23例经鞘内HSV-1特异性IgG抗体检测阳性的“HSV-1型性脑炎(HSE)”中19例PCR阳性,4例阴性患者病程均超过1个月。22例IgG阴性的“散发性脑炎”中7例PCR阳性,此7例皆于发病1周内检查CSF,其中2例取材于发病当日。1周后复查7例患者,CSF PCR仍为阳性,IgG皆阴性,提示PCR适用于HSE的早期诊断。     

化学发光免疫法检测粒细胞抗体IgG的研究

作者以ＡＢＥＩ－ＣｏＣｌ＿２－Ｈ＿２Ｏ＿２作为化学发光指示系统，用固相竞争法检测５８例白细胞减少症患者、４１例无白细胞减少症患者及３２例正常人等的粒细胞抗体ＩｇＧ。判断标准采用正常人血清化学发光强度指数法。实验结果表明，白细胞减少症患者血清中粒细胞抗体阳性率明显高于无白细胞减少症患者（Ｐ＜０．００５）。本法敏感性为４３．１％，特异性为９０．２％，准确性为６２．６％，是一种灵敏而准确的方法，能将粒细胞包被试管在室温下较长时间保存，以供临床监测粒细胞抗体，大大缩短检测时间。     

慢性肺心病并发多器官衰竭（附70例报告）

１９８６～１９９２年我院共收治急性发作期慢性肺心病１９６例，其中因严重肺部感染发生多器官衰竭（ＭＯＦ）者７０例（３５．７％），平均受损脏器２．５个，死亡２６例，总病死率为３７．１％。其中２和３个脏器受损者的病死率分别为２０．１％和４４．４％，而４和５个脏器受损者则均死亡。血气分析显示ｐＨ和ＰａＯ２值与受损脏器数目呈负相关，而ＰａＣＯ２值与受损脏器数目呈正相关。本文讨论了肺心病因肺部感染并发ＭＯＦ的发病机理，并提出防治的措施。     

Effect of interleukin-8 on glomerular sulfated compounds and albuminuria

To evaluate the effect of interleukin-8 (IL8) on glomerular basement membrane (GBM) sulfated compounds and albuminuria, we infused IL8 in 1% bovine serum albumin (BSA) for 5 days into the left renal artery of Holtzman male rats at the rate of 10 μl/h using an osmotic pump. Control rats received 1% BSA. A significant increase in urinary albumin/creatinine ratio was seen on the last day of IL8 infusion (0.38±0.11, mean ± SEM) when compared with albumin/creatinine ratio prior to infusion (0.19±0.04, P = 0.04). No significant differences in urinary albumin excretion prior to and after infusion of 1% BSA were observed. On the last day of infusion, rats were injected with ³⁵sulfate (1.0 mCi/200 g body weight) intraperitoneally and killed after 8 h. Glomeruli were isolated and GBM obtained. After 5 days of IL8 administration, there was a significant increase in ³⁵sulfate uptake by GBM of the infused kidney (76±10 cpm/dry glomerular weight, mean ± SEM) compared with the uptake seen in the contralateral kidney (53±9, P = 0.05). The in vivo infusion of IL8 increased the ³⁵sulfate uptake by GBM and augmented the urinary albumin/creatinine ratio, suggesting that IL8 may induce albuminuria by altering the metabolism of the GBM sulfated compounds. This hypothesis needs to be confirmed by studies on glomerular charge selectivity and GBM anionic sites during the course of the infusion. Moreover, the persistence of the effect needs to be evaluated by prolonging the infusion for more than 5 days. Received June 3, 1996; received in revised form and accepted October 18, 1996

In order to investigate the regulatory effect of acupuncture on obesity patients with the Stomach-Intestine Excessive Heat Type, the pre-acupunctureal and post-acupunctural obesity index and biochemical indices of 718 simple obesity patients with Stomach-Intestine Excessive Heat Type were observed. It was showed that the marked weight loss effect was achieved in the cases by acupuncture, and the biochemical indices improved. It suggests that acupuncture had a optimal regulatory effect on the function of nerve, endocrine, digestion and energy metabolism.     

高原环境下大鼠对硒制剂耐受力的实验研究

本实验将大鼠从上海空运至兰州，很快转至高海拔地区，用光镜及电镜观察了亚硒酸钠对大鼠的影响。结果发现在高原环境下大鼠对硒的耐受力减低，引起了大鼠猝死半加得高原缺氧对心肌的损伤，降低了大鼠高原适应性。本文还对其耐受机理进行了初步讨论。
