B／M混合组织球铁中Si的作用研究

研究了生产B／M混合组织球铁时Si的作用。结果表明，在不添加或少量添加合金元素条件下，通过淬火处理获得B／M混合组织球铁时，球墨铸铁基体中贝氏体数量随Si含量的增加而增加，而残余奥氏体的数量则明显减少；随着Si含量的增加TTT曲线左移，这种现象不同于Si在钢中的情况。

The antiviral effect of Keishi-ni-eppi-ichi-to,a tranditional Chinese herbal medicine,on influenza A2(H2N2) virus infection in mice

The antiviral effect of Keishi-ni-eppi-ichi-to (TJS-064), a traditional Chinese herbal medicine, was investigation in mice infected with influenza A₂(H₂N₂) virus. When mice exposed to 5 LD₅₀ dose of the virus were treated orally with a 70 mg/kg dose of TJS-064 1 day before and 1 day and 4 days after the infection, 100% survived over a 25-day experimental period. At the end of this period all the control mice, treated with saline alone, had died; their mean survival time in days (MSD) was 11.2 days. When mice infected with a 10 LD₅₀ dose of the virus were treated with TJS-064, the MSD was >17.4 days and there was a 50% survival rate, while the control group had a MSD of 8.7 days and 0% survival rate. No significant antiviral effect TJS-064 was observed when the agent was administered orally to mice infected with a 100 LD₅₀ or large dose of influenza virus. Pulmonary consolidation, virus titers in lung tissues and HAI titers in sera of infected mice treated with TJS-064 were all significantly lower than those of infected mice treated with saline. Interferon activities were detected in sera of mice treated with the agent at a dose of 100 mg/kg orally. Since viricidal and viristatic activities of the agent against influenza virus were not demonstrated, the antiviral effects of TJS-064 may be expressed through the host's antiviral functions including interferon production.     

Genetic ecology: A new interdisciplinary science,fundamental for evolution,biodiversity and biosafety evaluations

Genetic ecology is the extension of our modern knowledge in molecular genetics to studies of viability, gene expression and gene movements in natural environments like soils, aquifers and digestive tracts. In such milieux, the horizontal transfer of plasmid-borne genes between phylogenetically distant species has already been found to be much more frequent than had been expected from laboratory experience. For the study of exchanges involving chromosomally-located genes, more has to be learned about the behaviour of transposons in such environments. The results expected from studies in genetic ecology are relevant for considerations of evolution, biodiversity and biosafety. The role of this new field of research in restoring popular confidence in science and in its biotechnological applications is stressed.

棉铃虫细胞系SFE—HA—8212的克隆化及对HaSNPV受纳性提高的克隆系的建立

用细胞临界生长密度法对棉铃虫蛹卵巢细胞系ＳＦＥ—ＨＡ—８２１２进行克隆化，获得８株克隆细胞系．各株克隆细胞系各自的形态较为均一，但相互间在形态、生长特性、对病毒受纳性等方面有很大差别，其中一株ＣＳ细胞对棉铃虫单粒包埋型核型多角体病毒（ＨａＳＮＰＶ）的受纳性明显高于ＳＦＥ—ＨＡ—８２１２细胞，形成多角体的细胞比率、多角体的产量、游离病毒粒子的产量及多角体蛋白的产量均有提高，是研究和应用ＨａＳＮＰＶ的有效系统．
