无界绝对正则序列强律的收敛速度

本文进一步讨论了无界绝对正则序列(未必平稳)的Marcinkiewicz-Zygmund强律的收敛速度。在对随机变量的矩与相对系数给出一定的限制后,得到了与[2]中主要结果相应的结论。     

大气中的非线性Rossby波和Pseudo-Rossby波——(Ⅰ)正压大气情形

本文利用相角函数和常微分方程相轨线分析方法,讨论了半地转近似下正压Rossby波的存在和求解问题;结果表明:在描述Rossby波的方程中,除了具有通常意义的Rossby波解外,还存在一支Pseudo-Rossby波解;而且正压Rossby波的频率对一定的波动有一确定上界,这个上界由大气平均厚度与地理纬度确定;同时也分析了波动特征参量与拟能及地理参数间的关系.     

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.
