Three virus-resistant L cell mutants were selected with mutagen-selec-tion method. These mutant cell lines were found to show marked changes in interferon induction and action systems. An accelerated interferon induction response was observed in mutant cell cultures when they were exposed to NDV. Induced mutant cells synthesized interferon mRNA more quickly, and the interferon titers after induction with poly 1 : C were higher in mutant cell lines than in the parent cell line. One virus-resistant L cell mutant...

Three virus-resistant L cell mutants were selected with mutagen-selec-tion method. These mutant cell lines were found to show marked changes in interferon induction and action systems. An accelerated interferon induction response was observed in mutant cell cultures when they were exposed to NDV. Induced mutant cells synthesized interferon mRNA more quickly, and the interferon titers after induction with poly 1 : C were higher in mutant cell lines than in the parent cell line. One virus-resistant L cell mutant was found to be more sensitive to the anti-cell-division activity caused by intracellular pppA2'P5'A2'P5'A.Results suggested that changes in interferon gene expression might account for the antiviral activity of these cell mutants.

Observations on the morphology of BJAB cells were made before and after infection with Epstein-Barr Virus (EB virus) under scanning electron microscope. The surface of uninfected BJAB cells was covered with filopodia instead of microvilli which are the major surface feature of cultivated Burkitt lymphoma cells. One day after infection, the filopodia became somewhat thick and short in a portion of cells, while in the others the filopodia even virtually disappeared and the surfaces seemed to be undulated with...

Observations on the morphology of BJAB cells were made before and after infection with Epstein-Barr Virus (EB virus) under scanning electron microscope. The surface of uninfected BJAB cells was covered with filopodia instead of microvilli which are the major surface feature of cultivated Burkitt lymphoma cells. One day after infection, the filopodia became somewhat thick and short in a portion of cells, while in the others the filopodia even virtually disappeared and the surfaces seemed to be undulated with varying number of scattered "fingerlike" projections. This type of surface morphology was more predominant in the third day's infected preparations, and furthermore, clusters of blebs began to be observed. The number of bleb cells increased afterwards, at the seventh day a majority of cells had a "bleb-like excresence" appearance, very similar to the characteristic surface morphology of human myeloma cells. This typical surface architecture maintained without observable change during cell passages in vitro at least for five months. Since infection with inactivated EB virus could not induce such effects on BJAB cells as that mentioned above, it is considered the presence of EB virus genome and the expression of viral gene(s) might be involved in the changes of BJAB cell surface morphology.

在扫描电镜下观察BjAB细胞在感染EB病毒以后表面形态的变化。未受感染的BjAB细胞以表面布满丝状伪足者最多见。感染1天后,部分细胞丝状伪足缩短变粗,另部分则丝状伪足几乎全部消失,细胞表面略现皱褶和分布着疏散的“手指样”结构。感染后3天时细胞突出的变化是表面皱褶更明显,更多见;而且开始看到表面泡状结构。这种泡状结构的细胞在感染5天时数量增多,而7天后大部分细胞已呈“泡样瘤”状。观察感染后5个月的细胞,这种表面结构仍保持不变。由于用灭活的EB病毒在相同条件下感染这种细胞,表面形态未见改变,所以这种表面形态的变化应与EB病毒感染,并设想同EB病毒基因组的存在和表达有关。

The lactic dehydrogenase and its isozymes of the nasopharyngeal epithelium ofthe normal and N,N'-dinitrosopiperazine-treated rats and the respiratory epitheliumof the middle and later developmental stages of the rat foetus were studied using hi-stocytochemical method.It was found that the lactic dehydrogenase in the normalnasopharyngeal epithelium was of considerable activity and its isozyme patternwas of M type.The enzymatic activity was elevated in the various stages ofcarcinogenesis.M type activity increased during hyperplastic and dysplastic stages,while both M and H types increased in the cancer.The total activity andthe isozyme pattern in cancer resembled that of the middle stage of the rat foetus.These findings suggested that there might be some disorders in gene expression duringcarcinogenesis.In this presentation the alterations of the lactic dehydrogenase werecompared with that of the acid esterase.It was found that both the lactic dehydro-genase and acid esterase increased during the hyperplastic stage after carcinogen trea-tment but the former iucreased in the stage from dysplasia to neoplasia,while este-rase decreased or even disappeared completely.Attempt to use these enzymatic marke-rs for the differential diagnosis of the human nasopharyngeal carcinoma is underway.

本文观察了正常大鼠鼻咽上皮及用 DNP 诱发的大鼠鼻咽上皮癌变过程中乳酸脱氢酶及同功酶的分布和变化特点,结果观察到在增生、非典型增生及癌变过程中有乳酸脱氢酶活性增加以及在癌灶中的 M 型、H 型同功酶均增加。为探讨鼻咽上皮癌变过程中基因表达的变化和病理诊断提供某些线索。
