异位心(胸腹型)1例报告

异位心是罕见的先天性畸形,以胸部型心异位最为常见。我们遇到1例胸腹型异位心,为明确心内畸形作了全面检查,现报告如下.患者,女,19岁,自幼发现心脏杂音,平时易受凉发烧,活动后气喘,一岁后逐渐出现紫绀,无蹲踞及晕厥史.发育营养较差,口唇、面部紫绀,杵状指趾。BP110/70mmHg,P88次/分。胸部对称,     

~(99m)Tc-甲氧基异丁基异腈首次通过法心室显像评价左心室收缩功能

应用９９ｍＴｃ－甲氧基异丁基异腈（ＭＩＢＩ）对２９例受检者进行首次通过法心室显像，测定左室射血分数（ＬＶＥＦ），并与同期平衡法心室显像测得的ＬＶＥＦ进行相关分析。结果：首次通过法和平衡法心室显像测得的ＬＶＥＦ分别为（４６．５±１６．７）％、（４９．１±１６．１）％（Ｐ＞０．０５）。相关分析结果显示，二者有明显的相关（ｒ＝０．７８７，Ｐ＜０．０１）。结果表明：９９ｍＴｃ－ＭＩＢＩ为心肌显像剂，采用首次通过法心室显像，在观察心肌血流改变的同时，可准确可靠地评价左室收缩功能状态。     

卡价苗接后卡疤与PPD试验关系探讨

通过１８８例儿童结核菌素试验，探讨卡介苗接种后卡疤与ＰＰＤ试验的关系。提示介苗接种后１２周至１年内的ＰＰＤ试验阳性率最高，随接年限的长阳性率逐渐下降；接种后有卡疤与无卡疤的ＰＰＤ试验阳性率吸局部硬结平均直径均无明显差异，提示以有无卡疤判断病人体免疫是否成功，并以此评价人避免免水平有一定的片面性，应以ＰＰＤ试验衡量抗结核免疫力较为客观可靠。     

结肠癌增殖细胞的研究

增殖细胞核抗原(PCNA)与细胞分裂、DNA合成关系密切,核仁组成区嗜银蛋白(AgNOR)与细胞增殖密切相关。我们将PCNA和AgNOR作为反映细胞增殖的指标,探讨它们与结肠癌组织学类型、肠壁浸润深度、淋巴结转移间的关系。现报道如下。

EXPRESSION OF C-MYC AND N-RAS ONCOGENES IN HUMANHEPATOCELLULAR CARCINOMA AND PANCREATIC ADENOCARCINOMA A BIOCHEMICAL ANDIMMUNOCYTOCHEMICAL STUDY

WiLh RNA-DNA dot blot technique, the expression of c-myc and N-ras oncogenes in human hepato cellular carcinoma was found to be higher than in tie non-cancerous liver tissue adjacent to the carci noma (p<0.01). The expression of both oncogenes was high in the fetal liver and gradually decreased with age during development, indicating a probable co-operation of c-myc and N-ras. Immunocytochemi- cal analysis showed changes in protein products of c-myc hepatocellular carcinoma and its nan cancerous tissue were similar to those in mRNA expression. The same was true for the fetal liver during its development. A comparable study was also made on the ex pression of c-myc and N-ras oncogenes in limited samples of human pancreatic adenocarcinoma and its noncancerous tissue. The results are inconclu sive, and further studies are needed.
