Protective effect of Shigyaku-to,a traditional Chinese herbal medicine,on the infection of herpes simplex virus type 1 (HSV-1) in mice

The antiviral activity of Shigyaku-to (TJS-109), a traditional Chinese herbal medicine, was investigated in mice infected with herpes simplex virus type 1 (HSV-1). TJS-109 is a combination of the medicinal plant extracts fromZingiberis siccatum rhizoma,Aconiti tuber andGlycyrrhizae radix in a specific proportion. Mice infected with a 10 LD₅₀ dose of HSV-1 were treated with TJS-109 orally at doses of 1.25 to 20 mg/kg 2 days before, and 1 and 4 days after the infection. The treated groups had 80% (1.25 mg/kg), 40% (5 mg/kg) and 23% (20 mg/kg) mortality rates 25 days after the infection as compared with a 100% mortality rate in control mice treated with saline. When HSV-1 infected mice (recipients) received CD8⁺T cell fractions derived from spleens of mice treated with TJS-109 (donors), 70% of recipients survived, as compared with 0% survivors in the groups of mice treated with saline, B cell fractions, CD4⁺ T cell fractions or macrophage-enriched fractions prepared from the same donors. TJS-109 did not show any virucidal activities against HSV-1 or any virostatic activities on the growth of HSV-1 in Vero cells. These results suggest that TJS-109 protected mice exposed to lethal amounts of HSV-1 through the activation of CD8⁺ T cells.

黔东湘西寒武纪碳酸盐斜坡上的风暴沉积

黔东万山－湖南新晃地区的寒武系中风暴沉积发育。风暴沉积的岩石类型主要是砾屑石灰岩和砂屑石灰岩，砾屑石灰岩从细砾屑石灰岩到巨砾屑石灰岩均有，但以中砾屑石灰岩最多，砾屑大都呈板状，但有的呈近等轴状。其排列方式呈平行状和迭瓦状。砂屑石灰岩具递变层理、平行层理、丘状层理、单向交错层理等。砾屑石灰岩和砂屑石灰岩夹于大套暗色中薄层碳酸盐岩中，为斜坡环境中的风暴沉积。     

金川贫化电炉渣最佳Fe／SiO_2的研究及其应用

本文首次借助计算机建立了金川公司贫化电炉渣含钴与Ｆｅ／ＳｉＯ_２之间关系的数学模型，优化计算结果表明：在现有生产条件下，渣含钴最小时的最佳Ｆｅ／ＳｉＯ_２为１．２８，将此结论应用于金川贫化电炉生产，有效地降低了贫化电炉渣含钴、镍；年经济效益为１３０２．５万元。     

聚2，5－二甲氧基苯胺薄膜电极对儿茶酚的电催化作用

研究了电化学方法制备的聚２，５－二甲氧基苯胺薄膜电极（Ｐ２５ＤＭＡｎ／Ｐｔ）对水溶液中儿茶酚的电催化作用，以及影响催化作用的主要因素，结果表明，在酸性较强的水溶液中，在较充的浓度范围内（儿茶酚的浓度为１×１０￣－１～５×１０￣－５ｍｏｌ／Ｌ）均有很好的电催化作用，催化电流与儿茶酚浓度呈良好的线性关系。     

不可约非负矩阵的周期与指标集的分类算法

文［１］和［２］讨论了不可约非负矩阵指标集的分类理论，在此基础上，本文给出了不可约非负矩阵的周期与指标集的分类算法。这一算法能同时求出周期与同余类，当矩阵的阶不大时，该算法容易在图上实现。
