To determine whether there are different membranous antigem expressions among primary human hepatocellular carcinoma cells and hepatocytes, four intact human hepatoma cell lines namely BEL-7402, QGY-7703, MAH, SMMC-7721 as well as Hela cells were used to immunize New Zealand white rabbits. Antisera obtained were adsorbed on powdered human liver. Frozen sections from hepatocellular carcinoma (HCO) (33 cases), and non-cancerous liver tissue (10 cases) were stained by indirect immunofluorescence and PAP techniques....

To determine whether there are different membranous antigem expressions among primary human hepatocellular carcinoma cells and hepatocytes, four intact human hepatoma cell lines namely BEL-7402, QGY-7703, MAH, SMMC-7721 as well as Hela cells were used to immunize New Zealand white rabbits. Antisera obtained were adsorbed on powdered human liver. Frozen sections from hepatocellular carcinoma (HCO) (33 cases), and non-cancerous liver tissue (10 cases) were stained by indirect immunofluorescence and PAP techniques. The incidence of positive membranous staining of cancer cells among 33 cases of HCC using various antisera wero as follows: anti-BEL-7402, 78.8%; anti-QGY-7703, 69.7%; anti-MAH, 48.5,%; anti-SMMC-7721 and anti-Hela, 15.2%; but the cytoplasm and nuclei of HCC wore negative. The above membranous staining, of antisera treated jiver tissue and hepatocytes surrounding HCC or non-HCC hepatocytes were negative. In some cases of HCC and non-HCC liver tissues, weak staining of the sinus wall could be seen. Using the microspectrometer, 8 kinds of antisera treated sections of HCC and liver tissue using PAP staining technique were scanned for comparing the intensity of staining quantitatively in the same sections. The intensity was 2-17 times higher in HCG than in the liver tissues surrounding HCC. These findings suggest that there are different membranous antigen expressions between HCC and the surrounding liver cells.

为探讨人肝癌细胞膜是否存在与癌周肝细胞膜不同的抗原表达,作者用4株人肝癌体外培养细胞分别免疫家兔,抗血清经肝粉吸附后对外科切除的33例肝细胞癌及癌周组织,10例非癌性肝病组织的冰冻切片进行了间接免疫荧光及PAP染色。结果肝癌细胞膜染色阳性,胞浆、胞核阴性;癌周组织及非癌性肝病组织中肝细胞膜也呈阴性。部分癌及非癌组织其血窦壁显弱阳性。作定量分析的结果表明,在同一张切片中,肝癌组织染色强度为癌周组织的2~17倍。结果提示肝癌细胞膜上有癌周肝细胞膜不表达或表达甚微的抗原存在。

In order to study the changcs in morphology and permeability of aortic endothelial cells (EC) in spontaneously hypertensive rat (SHR),14 SHR and 2 Wistar Rat (WR) were observed. The morphologic changes of EC were observed with Hachen technique, three degree Slices (Waxen. Semithin and Ultrathin Slice) and SEM method. The permeability changes of aortic intima were shown with methods of Evans blue and HRP reaction. The results drown from above mentio-ned methods indicated that chronic hypertension could produce the lesions of EC,the slight lesion appeared in the contraction of the EC, the enlargement of juncti-onal spaces between EC and the weak staining or local lossing of argyrophilic lines of EC, more serious lesions were the degeneration, necrosis, lacal desqua-mation of EC crater-like lesion formation of EC and lossing of intimal intergrity. This experiment also showed that the lesion of EC induced the mesease of intimal permeability that adaptive thickening of arterial intima and medium would occur with increasing blood pretsure.

The development of antibody—producing immunocytes was examined in the popliteal lymph nodes of the guinea pig during their primary response to horseradish peroxidase (HRP). The scattered cells containing antibody were first observed in the medulla region and the cortex region 8 days after the HRP. injection. The cells showing weak staining intensities were mainly small and intermediate lymphocytes. The considerable increase of antibody positive cells, mainly proplasma and plasma cells, was observed in lymph nodes between 20 and 24 days after the HRP injection. The proplasma and plasma cells with an enlarged nucleus and cell size showed the intermediate and intense staining intensities. Between 30 and 50 days after the HRP injection, the number of antibody—producing cells decreased significantly. The developmental approach of antlbody-producing immunocytes during the primary response was similar to that daring the secondary response described in the previous report, except that the antibody-producing cells appeared 8 days after the primary injection while they appeared 2—3 days after the boost.

本文以辣根过氧化物酶(HRP)与福氏完全佐剂混合成的乳液对雄性豚鼠作一次免疫,追踪腘淋巴结中抗体形成细胞的分化途径和变化。一次免疫后抗体形成细胞分化的途径与前文所述的二次免疫是相同的,只是免疫应答开始时间较二次免疫晚。在免疫后8天的皮质区和髓质区,同时出现分散的含抗体的阳性细胞,主要是浅棕色的小淋巴细胞和中淋巴细胞。从10天起,这二个区域的阳性细胞明显增加,细胞染色加深,至24天,阳性细胞大量增多达高峰,以棕色和栋褐色的前浆细胞和浆细胞为主,淋巴结的大部分区域充满着阳性细胞。从30天起,阳性细胞在皮质和髓质区都急副下降,至50天,淋巴结中只存在少数分散的阳性细胞,部分细胞成为不规则形的残留浆细胞。
