脾部分切除术的技巧与体会

目的：最大限度地保留脾组织及脾功能可使机体避免或减少因无脾而导致不良后果。方法 主要操作技巧,充分游离脾脏,解剖脾门时勿伤及脾极动脉,结扎并切断受损之脾叶,段血管,垂直褥区缝合残面,结下衬以明胶海绵,打结力度适宜;缝合完毕后观察１５分钟方脾还纳腹腔,结果 ２０例患者行脾部分切除术。１例出现脾窝积液,并经穿刺油液后治愈,余者均痊愈出院,１７例患者随访１－９年,免疫功能正常,远期疗效优良,结论,对脾     

Chronic effect of endosulfan on the testicular functions of rat

Aim: To find out the toxic effect of endosulfan on the tesficular function of pubertal rats, Methods: Male rats of pu-bertal age were orally administered endosulfan at a dose of 1.0 mg/kg body weight for 30 days. Twenty-four hours af-ter the last tmagnent, the rats were sacrificed and the testis, epididymis, seminal vesicles and ventral prostate were re-moved and weighed. A 10 % testicular homogenate was prepared for biochemical estimations. Results: In endosul-fan-treated rats, there were a reduction in the body weight and the weights of testis and accessory sex organs, a de-crease in the testicular lactate and pyruvate activities, and in the testicular DNA and RNA concentrations, whereas thetesticular protein concentration was slightly increased; the specific activity of testicular steroidogenic enzyme, 33OH-steroid dehydrogenase and the ascorbic acid level were decreased, which were correlated with a decrease in steroidoge-nesis. The lysosomal enzyme acid phosphatase and brush-border enzyme alkaline phosphatase activities were also de-creased in the testis of treated rats. Conclusion: In puhertal rats, endosulfan treaanent inhibits the testicular functions.(Asian J Androl 1999 Dec; 1 : 203 - 206)     

术后患者肠道吸收乳果糖、甘露醇的变化与创伤程度的关系

目的 测定手术后患者肠道对甘露醇和乳果糖吸收的变化,并研究这些变化与手术应激程度的关系。方法 用小剂量乳果糖（ｌａｃｔｕｌｏｓｅ,Ｌ,２ｇ）和甘露醇（ｍａｎｎｉｔｏｌ,Ｍ,１ｇ）的方法测定２０例腹部手术患者术前,术后第５第和１０天乳果糖／甘露醇比值（Ｌ／Ｍ比值）的变化。用急性生理和慢性健康状况评分方法Ⅱ（ＡＰＡＣＨＥⅡ）对患者的创伤程度进行评分。用带电化学检测器的高压液相色谱仪测定尿中的乳果糖和甘     

多普勒超声心动图评估左心室舒张末压的研究

目的探讨多普勒超声心动图评估左室舒张末压的有效方法与指标。方法对６８例病人采用左心导管测压及经胸多普勒超声心动图检测。结果对比研究显示,联合肺静脉与二尖瓣血流频谱分析优于二尖瓣血流频谱分析,肺静脉Ａ峰和二尖瓣Ａ峰时限差值（ＰＡｄ－Ａｄ）与左室舒张末压实测值呈最佳相关性（ｒ＝０．７２,Ｐ＜０．０１）。结论认为应用多普勒超声心动图测定ＰＡｄ与Ａｄ,并以其差值估测左室舒张末压,是一项简便、可靠的无创性评估左室舒张末压的方法。ＰＡｄ－Ａｄ≥０可作为临床判断左室舒张末压增高［≥２．０ｋＰａ（１５ｍｍＨｇ）］的一项半定量指标。     

狭窄型陈旧性肛裂患者肛门功能测试报告

１９９２年以来我们对狭窄型陈旧性肛裂患者采用肛门皮肤粘膜搭桥术及纵切横缝皮瓣移动术的两组各３０例术前、术后分别进行了肛门功能测试,并与正常人组３０例进行了对比观察,现总结如下。１资料和方法１．１测试对象将６０例诊断为狭窄型陈旧性肛裂患者（符合Ⅲ期肛裂...     

下肢多关节功能康复器的临床应用114例

缩短疗程,预防和减少合并症,最大限度的恢复功能是骨科医师治疗的目的。传统的治疗方法,以静为主,由于较长时期的固定常引起关节囊粘连、挛缩、肌肉萎缩、关节功能恢复不全甚至僵直等合并症［１,２］。７０年代Ｓａｌｔｅｒ提出了有别于固定原则的关节持续被动运动（...
