鸡胚第一对弓动脉的发生

用印地安墨汁注入活体鸡胚心脏，在体现显微镜下观察１１２例第１０～２０期鸡胚第一对弓动脉的发生。第一对弓动脉于第１０期出现，至第２０期退化消失。第一对弓动脉出现时尚无相应的第一咽弓，随着第一咽弓的出现，第一对弓动脉的起始端形成一个突入第一咽弓内的动脉瘤样隆起，此隆起随着第一咽弓的增大逐渐发育成一对贯穿第一咽弓的弓状血管。第一对弓动脉可以分为位于第一咽弓内的近侧段和位于此咽弓之外，与背主动脉相连的远侧段。     

外周伤害性刺激及吗啡对大鼠丘脑束旁核痛抑制-兴奋神经元电活动的影响

应用细胞外微电极技术,观察和记录了Pf痛反应神经元对伤害性夹尾、伤害性电刺激坐骨神经和检验性刺激及脑内微量注射吗啡前后电活动变化的情况。在67只Wistar大鼠右侧Pf内记录了309个痛反应神经元,其中PI-EN64个,占神经元总数的20.71%。PI-EN对伤害性夹尾和电刺激坐骨神经均发生特异性的抑制-兴奋反应,对非伤害性刺激则不发生反应。伤害性刺激诱发放电之前有     

Effects of Activated Complement on Lung Fluid Exchange in Conscious Goats:Role of Superoxide Anion

The effects of zymosan-activated plasma(ZAP)on lung fluid exchangeand on superoxide anion production by granulocytes were studied in 8 consciousgoats with chronic lung lymph fistula,It was found that after ZAP infusion, thecirculating granulocytes were activated and the release of superoxide anions wasmarkedly enhanced. There was an increase in lung lymph flow and proteinconcentration.It suggests that the superoxide anion released by the stimulatedgranulocytes can play a role in inducing lung injury by the activated complement.     

原发性醛固酮增多症的定位诊断与手术径路选择的初步研究——附10例报告

收治10例原发性醛固酮增多症。所有病例术前均经B超、CT扫描、血管造影及取肾上腺静脉血测醛固酮浓度4种定位方法检查。CT扫描和取肾上腺静脉血样分别获得75％和71.4％的肾上腺腺瘤诊断准确率。综合上述4种方法,7侧术前做出腺瘤定位诊断,其中5例获得术中和病理组织学证实,定位准确率为71.4％。并对手术入路的选择进行讨论,单侧腰切口仍然不能代替经腹切口。     

应用乳酸杆菌对非特异性阴道炎和滴虫性阴道炎的治疗观察

我们用乳酸杆菌制剂对30例非特异性阴道炎和29例滴虫性阴道炎进行了治疗及菌群分析。结果表明,这两种阴道炎病人的阴道乳酸杆菌的平均水平明显低于正常值,而肠杆菌、葡萄球菌和类杆菌却明显增多。因此,阴道炎可能是由于菌群失调引起的。乳酸杆菌是阴道正常优势菌,并对致病菌有拮抗作用,这对维持阴道微环境,保持健康状态是非常重要的。     

Percutaneous transluminal coronary angioplasty in a patient with paroxysmal nocturnal hemoglobinuria

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired chronic hemolytic anemia associated with an unusual susceptibility to hemolytic crisis, infection, and venous thrombosis which would be aggravated by a number of factors including surgery. We report a case of PNH undergoing percutaneous transluminal coronary angioplasty and discuss the corresponding perioperative management.     

99Tcm and 111In leucocyte scintigraphy in inflammatory bowel disease.

A comparative study of 99Tcm-hexamethylpropyleneamine oxime (HMPAO) and 111In leucocyte scintigraphy was performed in inflammatory bowel disease. Two hundred and thirty-four patients were studied, 146 had 99Tcm-HMPAO, 82 had 111In and six had both. The sensitivity, specificity and accuracy of the 99Tcm leucocyte scan were 96, 97 and 97%, respectively, and 96, 97 and 97%, respectively, for the 111In leucocyte scan. 99Tcm-HMPAO leucocytes demonstrated similar diagnostic accuracy to 111In-labelled leucocytes with improved image quality and reduced radiation dose.     

急性重复性缺氧小鼠脑组织中儿茶酚胺类神经递质含量变化的研究

用高效液相-电化学检测器测定急性重复性缺氧小鼠脑组织中DOPA、DA、NE和Ep等儿茶酚胺类物质的含量。结果发现:与空白对照组(A组)比较,缺氧1次的实验对照组(B组)及急性重复缺氧4次实验组(C组),随缺氧次数增加,小鼠脑组织中的DA含量显着上升(P<0.01),NE、DOPA含量明显降低(P<0.05或<0.01);A组与急性重复4次缺氧后饲养2d的实验对照组(D组)小鼠脑组织中儿茶酚胺类含量接近,没有统计学意义(P=23.77).结果提示脑组织中儿茶酚胺类物质可能参与急性重复缺氧小鼠的耐缺氧能力的形成,而且是一个可逆的快反应。     

Effect of Salvia miltiorrhiza on the left ventricular diastolic function in coronary artery stenosis

In 24 open-chest mongrel dogs, coronary artery critical stenosis were produced by a micrometer constriction on left circumflex coronary artery. It was reduction about 87% in lumen area. CBF, -Vce, -dp/dt max were decreased, T was increased (P less than 0.01). 15 minutes after stenosis, the Salvia miltiorrhiza injection was injected into left atrium. CBF, -dp/dt max, -Vce were increased and T was decreased after the injection of Salvia miltiorrhiza. Moreover, the change of CBF was the earliest. The results proved that the Salvia miltiorrhiza could improve the left ventricular diastolic function in coronary artery stenosis.     

乙型肝炎甲胎蛋白检测与重型肝炎预后指数评估的意义

给慢性活动肝炎患者输注人胎肝细胞悬液引起血清甲胎蛋白增高反应的初浓度为２０２±３８．３μｇ／Ｌ，其半衰期为１．７天；分布池为６．９一１０．２升。重型肝炎生存组血清甲胎蛋白显著高于死亡组，生存组甲胎蛋白与血清总胆红素呈非常显著相关，而死亡组两者无相关性。重型肝炎患者输注胎肝悬液后其血清甲胎蛋白进一步升高者，预后较好。取重型肝炎预后指数０．１为重型肝炎生死的截断点，判断预后的灵敏度、特异度、准确度和阳性预告值分别为７９．５％、８９．６％、８４．８％和８７．５％。重型肝炎预后指数的计算可作为判断预后与新疗法疗效的指标。
