THE EFFECT OF NITRIC OXIDE ON HEPATIC FIBROSIS IN RAT

The development of liver cirrhosis after hepatic injury remains a difficult clinical problem that is refractory to therapeutic intervention. A number of potential contributing factors have been proposed based on experi-     

茯苓对实验性肝硬变的治疗作用

采用四氯化碳、高脂低蛋白膳食、饮酒等复合病因刺激复制肝硬变动物模型,在肝硬变形成后,经茯苓醇治疗三周,结果表明对照组动物仍有肝硬变,而给药组动物肝硬变明显减轻,肝内胶原蛋白含量低于对照组,而尿羟脯氨酸排出量高于对照组,表明药物可促进实验性肝硬变动物肝脏胶原蛋白降解,使肝内纤维组织重吸收。     

CLINICAL AND LABORATORY OBSERVATION ON THE EFFECT OF GLYCYRRHIZIN IN ACUTE AND CHRONIC VIRAL HEPATITIS

Twenty cases each of acute and chronicviral hepatitis were treated with potassium gly-cyrrhizinate,and another 20 such cases weretreated with inosine and Poly I:C as controlgroup.Results showed that improvement of liverfunction,decrease of SGPT levels and negativeconversion of HBsAg and HBeAg were moremarked in the glycyrrhizin group than in thecontrol.Short-term follow-up of the 20 acutecases in the glycyrrhizin group showed clinicalcure in 17 and marked improvement in 3,whilethe 20 cases in the control group showed clinicalcure in 7,marked improvement in one,improve-ment in 7 and no effect in 5.Of the chroniccases,short-term follow-up of the 20 cases in theglycyrrhizin group showed clinical cure in 15,marked improvement in 2,improvement in oneand no effect in 2,while the 20 cases in the con-trol group showed clinical cure in 2,improve-ment in 5 and no effect in 13.Animal experi-ments revealed that glycyrrhizinic acid lessen-ed the liver damage induced by carbon tetra-chloride in rats,reduced the serum levels ofSGPT and triglyceride content in liver homo-genate,and promoted the detection of serumaFP.In experimental fatty liver and livercirrhosis,glycyrrhizinic acid markedly lessenedthe fatty changes and fibrohyperplasia.How-ever,resorption of fibrous tissue was not pro-moted in the rats with liver cirrhosis.

大鼠实验性肝硬变腹水形成及其与肿瘤坏死因子α关系的研究

目的：研究大鼠实验性肝硬变晚期腹水形成与肿瘤坏死因子α（ＴＮＦα）及肠源性内毒素血症的关系，探讨肝硬变腹水形成的机理。方法：以大鼠为实验对象，分为正常对照组（ｎ＝８）、肝硬变对照组（ｎ＝１２）和肝硬变伴腹水组（ｎ＝１８）。实验组采用复合因子复制肝硬变动物模型。各组均测定腹主动脉血中ＴＮＦα和内毒素水平，肝硬变组还测定了腹水量。结果：随着肝硬变形成，大鼠血中ＴＮＦα水平增高，各组含量分别为９０８３±１０７１ｎｇ／ｍｌ和９５７７±１２７６ｎｇ／ｍｌ（肝硬变组和肝硬变伴腹水组）。相关分析表明，肝硬变组腹水量与血中ＴＮＦα成正相关（ｒ＝０８６，Ｐ＜００５），内毒素水平增高，并与ＴＮＦα的浓度成正相关（ｒ＝０７５，Ｐ＜００５）。结论：肝硬变腹水形成与血中ＴＮＦα升高有关，而ＴＮＦα的升高则源于肠源性内毒素血症的形成。     

微波治疗宫颈糜烂496例临床疗效观察

宫颈糜烂是慢性宫颈炎常见的一种病理改变。病理性糜烂面长期得不到治疗，可由单纯性糜烂发展为颗粒型糜烂，乃至发展为乳突型糜烂，均属于慢性宫颈炎的范畴之内，是妇科的常见病及多发病之一。临床上常以阴道分泌物增多，易有血性白带、性交后出血、或伴腰酸腹痛、下腹坠胀为主要临床表现，长期得不到治愈严重影响妇女的身心健康、生活及工作。近几年来，我院对广大育龄妇女开展生殖保健工作，并进行普查普治。对息宫颈糜烂496例妇女重点使用微波进行治疗，临床疗效满意。现报道如下：

关于五味子降酶机理的初步探讨

关于五味子制剂治疗病毒性肝炎屡有报道,其特点是降谷丙转氨酶活力的效果迅速、幅度大。但对其降酶机理至今不清,看法不一,因而有必要通过动物实验加以阐明,供临床应用之参考。
