心脏微循环血管的扫描电镜观察Ⅰ.心脏血管球

应用血管铸型、扫描电镜观察方法，研究了２例成人及１例儿童的左冠状动脉前降支中段心肌浅层及其周围的脂肪组织内的心脏血管球的三维构筑。根据形态特点，将心脏血管球分为圆球型、柱型、多角型、捆绑型、绒团型及鸭梨型，并对各型心脏血管球的形态结构特点进行了描述，且阐述了这些心脏血管球的临床意义。     

56例高血压患者血液流变学观察

自1985年至1988年我们对56例高血压患者进行了全血粘度、血浆粘度,红细胞电泳、红细胞压积和血沉的测定,与50例正常人进行了比较。并在高血压病的各分期间进行了直线相关性检验,现将结果报告如下。     

人体解剖学国家精品课的创建与运作

中国医科大学人体解剖学于2004年获国家精品课程，这既是教育专家对我校解剖学教学工作多年积累、知识积淀、综合教学质量的肯定，又是对我们的莫大鼓舞和鞭策。在创建国家级精品课程过程中，我们有些体会，愿与国内同行共享。     

哺乳期营养对室间隔心肌细胞发育的影响——游离心肌细胞的形态测量

在心肌细胞分化性生长时期,改变新生鼠的哺乳期营养条件对这些鼠的空间隔心肌细胞将会产生暂时性作用和持久性影响。哺乳期高营养的暂时性作用是增加空间隔心肌细胞的大小和数量;而低营养的暂时性作用则是减慢室间隔心肌细胞的生长。哺乳期高营养的持久性作用是限制室间隔心肌细胞的过度肥大;而低营养则促进成熟鼠的室间隔心肌细胞的过度肥大。     

喉部骨肉瘤

喉部骨肉瘤首次报告于1942年，喉部恶性肉瘤是罕见的非上皮源性肿瘤，占喉部真性肿瘤的0．5％-1％。本文报告1例69岁女性喉部骨肉瘤，并复习了迄今所见的13例喉部骨肉瘤的文献报道，年龄51-79岁，其中男性12例，女性1例，9例接受了全喉切除手术。对喉部骨肉瘤的病因、临床表现、治疗和预后进行了客观的回顾性分析。病人最常见的主诉是声音嘶哑、吞咽障碍、呼吸困难和急性气道阻塞。诊断是比较困难的，虽然通过专科检查、纤维喉镜检查及CT扫描可以发现肿块，但常常需要多次取检，才能确诊。     

肝内HBcAg与血清学指标的关系及慢性乙型肝炎发病机理的探讨

We detected the presence and distribution of HBcAg in the liver by immunohistochemistry (ABC method) and the presence of HBV-DNA in serum (spot hybridization) and anti-HBe in serum (ELISA) from 59 cases of hepatitis B hospitalized in our hospital, including 47 cases of CAH, 5 cases of CPH, and 7 cases of subacute fulminant hepatitis. 1. HBcAg in the liver was detected in 25 out of 47 cases (53%) of CAH, in 2 out of 5 cases of CPH and in 4 out of 7 cases of subacute fulminant hepatitis. The total percentage was 53% (31/59). 2. There was no positive correlation between HBV replication activity and liver disease activity (P greater than 0.05). Our results did not support the hypothesis that suggests a direct cytopathic effect of HBV. Oppositely, the fact was that the presence, the amount and the patterns of HBcAg in the liver, and the presence of HBV-DNA in serum were predominant in mild CAH compared with those in severe CAH, predominant in CAH without cirrhosis compared with those in CAH with cirrhosis. There was a tendency of inverse correlation between HBV replication activity and liver disease activity. The results above were in line with the concept that HBcAg expressed on the surface of infected hepatocytes may be relevant target for T lymphocyte cytotoxicity. The results have suggested that an immune response to HBV is present, leading to the destruction of most infected cells. 3. There was a positive correlation between HBV-DNA in serum and HBcAg in the liver (P less than 0.005), indicating that HBV-DNA in serum can represent HBV replication.(ABSTRACT TRUNCATED AT 250 WORDS)

升主动脉瘤明胶酶活性变化的实验研究

目的 探讨明胶酶在升主动脉瘤形成过程中的活性变化及意义. 方法 将35只Wistar大鼠随机分为对照组和实验组.采用升主动脉缩窄鼠制备升主动脉瘤模型.于术后3～5个月取升主动脉,应用明胶酶谱分析及薄膜原位酶谱法检测动脉瘤明胶酶的活性改变. 结果 正常动脉壁外膜无或极少有明胶酶活性;动脉瘤壁的中膜与外膜明胶酶活性明显增强. 结论 明胶酶活性升高可能在升主动脉瘤形成过程中起重要作用.
