To explore the therapeutic effect and mechanism of Bushen Huoxue Xiezhuo Decoction (BHXD) in treating minute lesion nephropathy (MLN) in rats. Methods: The MLN model rats established by a single intravenous injection of Adriamycin were divided into the model and the BHXD groups, and a normal group was set up for control. The effects of treatment on renal function, hemorrheologic parameters, renal tissue transforming growth factor β1 (TGF-β1) expression and poly-anion sites on glomerular basement membrane were observed dynamically. Results: After treatment, all the parameters between the BHXD group and the model group were significantly different respectively, morphological observation also showed the pathological changes in the BHXD group were milder than those in the model group. Conclusion: BHXD treatment could markedly improve the renal function, alleviate blood hypercoagulability and hyperviscosity, protect the anion barrier and delay the progression of glomerular fibrosis and sclerosis.

Effects of acupuncture on the spontaneous discharge of nerve cells and levels of monoamine neurotransmitters in ventromedial nucleus of hypothalamus (VMH) of the obese rats were investigated. Results indicated that the levels of tyrosine (Tyr) and dopamine (DA) were lowered, the levels of 5-hydroxytryptamine (5-HT) and 5-hydoxyindole acetic acid (5-HIAA) increased, and the frequency of the spontaneous discharge of nerve cells in VMH lowered in the obese rat group as compared with the normal group. When acupuncture obtained the effect of weight reduction, the frequency of spontaneous discharges of nerve cells in VMH were markedly increased, and the levels of Tyr, DA and tryptamine (Typ) and 5-HT/5-HIAA ratio elevated, and the 5-HT level lowered. It is suggested that the virtuous regulative action of acupuncture on VMH might be one of the key factors in acupuncture for weight reduction.

镁与能量制剂对危重病人的临床意义

目的观察镁与能量(ATP-MgCl2)制剂对危重病人的临床意义.方法通过对实验动物进行缺血损伤,应用MgCl2、ATP、ATP-MgCl2对肝、肾、心、肺等器官的作用,使用冷冻蚀刻、组织化学及原子吸收光谱等技术,并结合光镜、透射电镜观察损伤器官的超微结构与Mg2、ATP浓度变化的关系,探讨外源性镁及能量制剂对损伤修复的效果.结果MgCl2、ATP两组对损伤器官均有保护作用(P>0.01).而ATP-MgCl2组对损伤器官具有良好的保护作用(P<0.01).该组细胞膜完整,胞质内有丰富糖原颗粒;质膜P面蛋白颗粒分布均匀,细胞核膜的P面上核孔分布均匀;细胞膜上、线粒体膜上及肌质网膜上均存在致密阳性产物,与正常组相近;原子吸收光谱显示线粒体内Qa2+明显下降.结论将外源性ATP-MgCl2应用危重病人,取得良好疗效.

Abstract The present sutdy was designed to assess whether changes in glycolipids and cyclic AMP contents might serve as markers for the diagnosis of malignancy in the liver. The experimental model was a transplantable murine hepatoma. Experimental mice were divided into three groups:(1) a therapeutic group. which had been transplanted with hepatoma and treated with the antimetabolism drug 5-flurouracil(0.2mg/day i.p).(2) a control group, which had been transplanted with hepatoma and treated with 0.2ml 0.9% NaCl day and (3) a normal group of mice . The ganglioside and cAMP contents in the hepatoma tissue, plasma cAMP, total and lipid-bound sialic acid levels and red blood cell memebrane sialic acid levels were determined. Results showed that the ganglioside content, total and lipid-bound sialic acid levels in the control group were significantly higher than those in the livers of normal mice(P<0.01) while these respective values in the therapeutic group were significantly lower than those in the control group(P<0.01).The cAMP levels of tumor tissues and plasma in the control group were lower than those in normal mice. No significant difference in red blood cell membrane sialic acid content was observed between the therapeutic and control groups though levels for both were higher than those in normal mice. These results indicate that ganglioside ocntent and sialic acid levels in hepatoma tissues were significantly elevated, and cAMP levels in hepatoma tissues were significantly decreased during proliferation and abnormal differentiation.Key words transplantable hepatoma, gangliosides , sialic acid, cyclic adenosine mono-phosphate, 5-flurouracil摘自Molecular and cellular biochemistry, 2000; Vol 207,29～33该杂志摘要被美国科学引证索引(SCI)收录

先天性髋脱位治疗前后股骨上端静脉造影的观察

为了观察先天性髋脱位治疗前后股骨上端血运变化,进一步探讨治疗后股骨头缺血性坏死的血运分布特点和发生因素,我院自1983年9月至1985年1月对29例先天性髋脱位患儿做了股骨上端静脉造影检查,现将结果报告如下.方法与结果造影方法:患儿仰卧位、全麻下于两侧股骨大粗隆下2cm处,分别用骨髓穿刺针,向股骨头方向刺入,止于股骨颈基底部,经电视透视证实后,快速注入76%泛影葡胺各10ml,每间隔2秒拍摄骨盆正位片1张,共摄5张,当拍完后间隔3分钟,再摄后1张,观察造影剂排空情况.
