    This communication is an analysis of the scanning results of sixty cases of clinically suspected hepatic space-occupying lesions which were subsequently pathologically proved. This series comprises 36 cases of primary carcinoma of the liver, 8 eases of metastatic carcinoma of the liver, 3 eases of schistosomal granuloma of the liver, 2 eases of liver cyst, 2 cases of liver abscess, and 1 case each of secondary mesothe-lioma of liver, cavernous haemangioma of liver,lymphangioma of liver, adenocarcinoma of gall-bladder,...

    This communication is an analysis of the scanning results of sixty cases of clinically suspected hepatic space-occupying lesions which were subsequently pathologically proved. This series comprises 36 cases of primary carcinoma of the liver, 8 eases of metastatic carcinoma of the liver, 3 eases of schistosomal granuloma of the liver, 2 eases of liver cyst, 2 cases of liver abscess, and 1 case each of secondary mesothe-lioma of liver, cavernous haemangioma of liver,lymphangioma of liver, adenocarcinoma of gall-bladder, retroperitoneal undifferentiated carcino-ma, carcinoma of transverse colon, congenital intrahepatic cholangiectasis, carcinoma of panc-reas and cholecystitis. We could observe the configuration, struct-ure, location and size of the liver by this method.Each kind of hepatic space-occupying lesions had its own characteristic appearences in the liver scans.When a positive finding in the liver scan,was obtained, no single case was mistaken; but in case of negative finding in the liver scan, the possibility of space-occupying lesions could not be ruled out. Fifty-nine cases in this series showed typical changes in the liver scans, only one case of primary carcinoma of the liver exhibited no area of decreased activity in the liver scan, thus produeing false-negative result.Radioisotope scanning of the liver is accurate and painless and is considered to be the best method in the diagnosis of hepatic spaceoccupying lesions, particularly in the diagnosis and differ-ential diagnosis of carcinoma of the liver.

    肝脏扫描术对肝脏占位性病变的诊断有很大的价值。我们总结了我院附属中山医院1959年以来300余例肝脏扫描中,经病理证实的60例临床上疑似肝脏占位性病变的扫描结果。本文着重讨论肝癌在扫描图上的表现及其与其他占位性病变的监别诊断,以及本方法和其他诊断方法的对比等。

    The changes of tyrosine transaminase activity (TAT) and nucleotide 5'-phosphodiesterase activity (5'-NPDase) during foetal development and carcinogenesis in rats and in human beings were observed. Results so far obtained indicate that (1) a higher positive rate of the fastest moving isoenzyme band for 5'-NPDase has been noted in AFP (-) patients with liver cancer, and (2) TAT, 5'-NPDase and AFP may be taken together as good markers for the study of gene expression during liver caroinogenesis and foetal...

    The changes of tyrosine transaminase activity (TAT) and nucleotide 5'-phosphodiesterase activity (5'-NPDase) during foetal development and carcinogenesis in rats and in human beings were observed. Results so far obtained indicate that (1) a higher positive rate of the fastest moving isoenzyme band for 5'-NPDase has been noted in AFP (-) patients with liver cancer, and (2) TAT, 5'-NPDase and AFP may be taken together as good markers for the study of gene expression during liver caroinogenesis and foetal development.

    本文测定了大鼠及人体胚胎发育和癌变过程中TAT和5′-NPDase活力变化,所得结果表明: (一)5′-NPDase快速同工酶区带在甲胎蛋白(AFP)阴性肝癌患者血清中阳性率较高。(二)TAT,5′-NPDase和AFP也许可作为研究癌、胚以及肝癌癌变过程中基因表达的三个互补生化指标。

    Observations on the localization of AFP in rat liver tissue in correlation to serum AFP dynamics during 3'-MeDAB carcinogenesis were carried out by the immunoenzyme technique and the radio-rocket-electrophoresis autography.The following results were obtained:(1) During the precancerous stage, AFP was found in a few liver cells in the pseudolobules, in the cells of the basophilio anaplastic regenerative nodules and in some of the "survival" liver cells and "transitional" cells. Most of these cells showed basophilio...

    Observations on the localization of AFP in rat liver tissue in correlation to serum AFP dynamics during 3'-MeDAB carcinogenesis were carried out by the immunoenzyme technique and the radio-rocket-electrophoresis autography.The following results were obtained:(1) During the precancerous stage, AFP was found in a few liver cells in the pseudolobules, in the cells of the basophilio anaplastic regenerative nodules and in some of the "survival" liver cells and "transitional" cells. Most of these cells showed basophilio cytoplasm and appeared dedifferentiated.(2) AFP was not detected in the bile duct carcinomas nor in most of the liver cell carcinomas of low grade malignancy, but was demonstrated in the poorly differentiated liver cell carcinomas. The intensity of AFP synthesis in liver cell carcinomas increased in coincidence with their activity in cell growth and cell proliferation but decreased with cell differentiation. AFP synthesis was not directly related to whether or not the cell was in the mitotic stage.(3) In the liver cell carcinomas, the extent of AFP positive reaction as visualized by the immunoenzyme technique basically paralleled the serum AFP level.The possible mechanism and the histologic basis of the serum AFP "saddle shaped" curve during 3'-MeDAB carcinogenesis are discussed, and a preliminary postulation on the histogenesis of liver cancer so induced is suggested.

    本工作采用放射火箭电泳自显术和免疫酶标记定位技术,对大鼠3'-MeDAB诱癌过程血清和肝组织甲胎蛋白(AFP)的动态变化和定位情况进行了观察。发现(1)肝硬化假小叶内的少数肝细胞、嗜碱性间变再生结节细胞、少数“幸存肝细胞”及少数“过渡性细胞”,具有合成AFP的能力。未见肝内其他类型细胞合成AFP。合成AFP的细胞大多具有胞浆嗜碱性、生长活跃和形态上去分化的特点。(2)未见胆管癌细胞合成AFP。肝细胞癌分化好的癌细胞绝大多数也未见合成AFP,分化差的癌细胞合成AFP的能力,基本上与其生长活跃程度呈正相关,与分化程度呈负相关,而与癌细胞是否处于核分裂阶段关系不大。(3)肝癌组织AFP酶标的强度和范围与血清AFP水平之间基本上有平行关系。此外,本文还就什么细胞合成AFP、血清AFP“马鞍型”变化的成因及病理组织学基础等进行了讨论,并根据实验结果,对大鼠3'-MeDAB肝癌的组织发生提出了初步的设想。
