改良面神经额支的体表定位

目的:通过改良的方法对面神经的额支进行体表定位,为临床手术提供更加适用的寻找面神经额支的方法.方法:对20侧防腐成人头部标本进行大体和显微解剖,测量在耳轮上点与外眦上点的连线上和耳屏上切迹点与外眦点的连线上,面神经的额支所经过的相对位置.结果:额支在耳轮上点-外眦上点的连线后段(3/10～4/5)±1/10的范围内跨过,在耳屏上切迹点-外眦点的连线后段(1/5-1/2)±1/9的范围内跨过.结论:面神经额支在两条标志线的特定区域跨过,手术中,切口应避开该危险区域.

立体视锐度与发样十五种元素关系初探

本文采用X－射线荧光分析法测定抚州市区152名健康中小学生（其中立体视锐度异常29人）的头发中Ca、Cr、Mn、Fe、Co、Ni、Cu、Zn、As、Mg、Pb、Cd、Mo、Se和Ge等15种元素的含量。结果表明立体视锐度异常儿童头发中Se元素含量较正常组低（P＜0．05），而Zn／Cu比值则明显高于正常组（P＜0．05），提示给予富含硒元素的食物，提高体内硒含量，调整Zn／Cu比值．对防治立体视税度导常发生具有重要作用。     

1,6—二磷酸果糖对手术后应激病人应用全肠外营养支持效果的影响

本文在胃癌行全胃或胃大部切除术引起的中等程度应激病人，随机分组对比观察了全肠外营养或ＴＰＮ加用１，６－二磷酸果糖的效果。结果显示，与单纯ＴＰＮ相比，ＴＰＮ加用ＦＤＰ后血清皮质醇和胰高血糖素等应激激素水平有所下降，尿中３－甲基组氨酸排出减少，累积氮平衡增加。     

RELATIONSHIP BETWEEN PLATELET CYTOSOLIC FREE CALCIUM CONCENTRATION AND PLASMA RENIN ACTIVITY

1. Plasma renin activity (PRA) and platelet cytosolic free calcium concentration ([Ca2+]i) were simultaneously determined in 18 untreated essential hypertensive subjects and 17 normotensive controls. A significant positive correlation was found between [Ca2+]i and PRA (slope = 42 nmol/l/ng/ml/h) in these 35 subjects. 2. Two determinations more than one week apart in nine subjects confirmed the parallel fluctuations of [Ca2+]i and PRA. A strict sodium restriction produced a progressive PRA elevation associated with a parallel rise in [Ca2+]i in one subject. 3. These results are consistent with the hypothesis that angiotensin II causes a concentration-dependent calcium mobilization.     

东北边境地区吸血蠓的调查研究

1980～1988年在东北边境的漠河、珲春县等10个县区采获吸血蠓2属37种,其中发现4个新种和4个国内新记录。不显库蠓(35.7％)和刺螯库蠓(34.9％)为优势蠓种。不同生境、场所和季节的蠓种组成有所不同。灰黑库蠓、淡角库蠓和端斑库蠓在整个活动季节均只出现一次高峰,而不显库蠓、刺螫库蠓和兴安库蠓在整个活动季节均出现两次高峰。刺螫库蠓的活动季节最长,为11旬,端斑库蠓最短,仅为5旬。刺螫库蠓、不显库蠓、兴安库蠓和灰黑库蠓在昼夜24小时均出现晨、昏两次活动高峰,而边缘库蠓只在凌晨出现一次晨峰。     

肝素联合VEGF预处理对人工血管内皮细胞生长及贴附率的影响

目的联合应用肝素及血管内皮细胞生长因子(VEGF)预处理以提高人工血管移植物内皮细胞(EC)生长及贴附率.方法联合应用肝素及血管内皮细胞生长因子预处理人工血管移植物,比较各组EC生长曲线和贴附率.结果肝素在体外与VEGF联合应用,可显著增加EC在人工血管内壁的贴附率,并对EC的增殖有一定的持续影响.结论肝素与VEGF联用,能促进EC在人工血管的增殖和贴附率.     

新生儿肠旋转不良的诊治分析

目的 分析新生儿期先天性肠旋转不良的临床特点及诊治方法。方法 回顾分析1996～2003年12例新生儿期先天性肠旋转不良，男10例，女2例，就诊时出生7～75d，平均45d，术前均经泛影葡胺口服及灌肠造影确诊后行Ladd术，附加阑尾切除术。结果本组1例术后并发粘连性肠梗阻二次手术行粘连松解术，其余11例无并发症，全部治愈出院。结论 本病的发病机制是由于并发急性肠扭转所致高位十二指肠的梗阻，主要临床特点是反复间断性胆汁性呕吐，口服和灌肠的消化道造影是诊断本病的最可靠依据。Ladd式手术是本病手术治疗的最佳选择，且效果满意。     

医源性腓总神经伤分析

The Effects of Allyl Isovalerate on the Hematopoietic and Immunologic Systems in Rodents

The Effects of Allyl Isovalerate on the Hempatopoietic and ImmunologicSystems in Rodents. HONG, H. L., HUFF, J. E., LUSTER, M. I.,MARONPOT, R. R., DIETER, M. P., HAVES, H. T., AND BOORMAN, G.A. (1988). Fundam. Appl. Toxicol. 10, 655–663. FemaleB6C3F1 mice plus male and female Fischer 344/N rats were gavagedwith allyl isovalerate (AIV) in corn oil at 0, 31,62, or 125(mice) and 0, 31. 62, 125, or 250 (rats) mg/kg body weight forfive daily exposures per week for a 2-week period. Hematologic,immunologic, and histopathologic studies were performed 48 to72 hr following the final treatment. AIV exposure had no effecton hematology or bone marrow cellularity in mice or rats. AIVexposure at 250 mg/kg was toxic to rats causing reduced weightgain and hepatotoxicity. In vivo and in vitro studies revealedthat pluripotent hematopoietic stem cells (CFU-S) and granulocyte-macrophageprogenitors (CFU-GM) in the bone marrow were decreased in thetreated mice. Hematopoietic suppression was correlated withthe reduction in the hexose monophosphate shunt metabolism ofbone marrow cells but the Embden-Meyerhof pathway and tncarboxylicacid pathway enzymes did not appear to be affected. Examinationof host resistance following Plasmodium and Listeria challengedid not demonstrate significant differences between treatedand control mice, nor were there other effects on the immunesystem. This suggests that the myelotoxic effects were minimaland of a degree that would not alter host resistance.
