患者男,59岁。1985年曾患肺结核,经二年抗结核治疗痊愈。以后有间歇干咳,痰中不带血。1989年8月咳出肉样组织一块(未送检)。1990年12月晨起又咳出花生米大小肉样组织一块,并有数口鲜血,无其他不适。一周内做纤维支气管镜检查无异常发现。将咳出组织送检,大小:2cm×1cm×1cm,  相似文献

Krukenters瘤是指卵巢内见含有粘液的印戒细胞、管状腺样结构和间质增生构成的转移癌。其原发癌多来自胃肠道,也可以来自胆囊、胰腺及乳腺等处。据统计70%来自胃癌,15%来自结肠癌,5%来自乳腺癌。近4年来我们遇到7例Krukenterg瘤,有5例原发癌在胃,1例在结肠,1例在直  相似文献

用羊抗兔肾血清复制肾小球肾炎模型的观察   总被引:2,自引:0,他引:2  
注射羊抗兔肾血清制造肾小球肾炎模型中发现:(1)如抗肾血清有溶血现象(当用兔新鲜红细胞吸附时造成的溶血),可增加动物的死亡率。一次注射抗肾血清复制动物产生明显蛋白尿的成功率为61%。(2)尿蛋白的多少可以反映病理改变的程度,但尿蛋白少于“ ”,在光镜下常不能见到明显改变,而电镜下可见上皮足突融合和电子致密物沉积于显著增厚的基膜上。(3)血胆固醇、尿素氮和血肌酐的水平与病理改变的严重程度密切相关。  相似文献

在长期应用左心辅助心泵或全人工心脏时,气压驱动管穿经皮肤而长久存在,气压驱动管的周围组织易于感染。为了预防入口处沿气压驱动管的感染,本实验应用了管周植被绒毛和在管周设置皮下圆盘。结果证明此装置在预防沿气压驱动管的感染中是简单而有效的。  相似文献

Twenty patients with jugular phlebectasia hadthe chief symptom of remittent bulging of the neck (unilateral 19, and bilateral l). Phlebography was performed in 18 patients and showed the lesion was mainly of two types: cystic and cylindrical. Those of external and anterior jugular veins were excised and those of the internal jugular veins were treated by plication. Pathologic studies on 11 excised veins revealed thin venous wall and that smooth muscle fibers were replaced by fibrous tissues. Etiologically, congenital hypoplasia of the venous wall led to the impedance of venous flow secondary to the particular anatomical position at the entry of the thoracic cage. Jugular phlebography demonstrated clearly the size, shape and position of these changes. We found that plication is effective in the treatment of internal ju- gular phlcbectasia and is worth recommending.  相似文献

In the present study we observed dynamically and systemically the changes of plasma somatostatin and glucagon in the peripheral and portal vein, and the changes of pancreatic immunopathology in the course of development of cirrhosis induced by CCl_4 and after portacaval shunt (PCS) in the cirrhotic rats as well as investigated their causes and correlationship. The results showed that hyperglucagonemia was caused by spontaneous portosystemic shunting and surgically induced portacaval anastomosis. Moreover, there was much higher level of glucagon in the portal vein with corresponding increase of A cells in PCS rats than those in the controls, indicating that another cause for elevation of glucagon was hypersecretion of pancreatic A cells. Our data demonstrated that both deterioration of liver function and portosystemic shunting might not be responsible for the elevated level of somatostatin in the cirrhotic rats with PCS. However, there was a closed positive correlation between plasma glucagon and somatostatin. Thus it was concluded that hyperglucagonemia stimulated the release of somatostatin. In view of the fact the elevated level of glucagon was much higher than that of somatostatin, there was probably a relative lack of somatostatin in cirrhosis with portal hypertension.  相似文献
