Carbazole-type compounds in crude oils

Carbazole-type compounds were analyzed using GC and GC-MS-MS. A relatively high concentration of carbazole-type compounds was detected in crude oils of different types (marine and non-marine) and different maturities (low mature and mature) in Tarinl. Liaohe and Keilu basins. The results suggest the ratios of 1, 8-dimethyl-/2, 7-dimethylcarbazole and benu, [a] carbazole/benzo [e] carbazole might be taken as petroleum migration parameters.     

Lewis酸的F_A标度及其应用

Ｌｅｗｉｓ酸的电负性（ｘＬ）和原子势（Ｚ／ｒｃ）是影响Ｌｅｗｉｓ酸硬软度（ＦＡ）的主要因素,本文给出了它们之间的数学关系式．根据ＦＡ值大小,把Ｌｅｗｉｓ酸分成三类,这与Ｐｅａｒｓｏｎ分类基本一致．用最小二乘法成功地建立ＦＡ与配合物的ｌｇＫｆ的线性回归方程,均通过Ｆ检验．

2-Carboxyethylgermanium sesquioxide,a synthetic organogermanium compound,as an inducer of contrasuppressor T cells

2-Carboxyethylgermanium sesquioxide (Ge-132), a synthesized organogermanium compound with immunomodulaing activities, was shown to be an inducer of anti-suppressor T cells in normal mice. The suppressor cell activity of T6S cells, a clone of burn-induced CD8⁺ IL-4-producing suppressor T cells, was clearly inhibited when a mixed lymphocyte-tumor cell reaction of the clone was conducted with splenic mononuclear cells from mice treated orally with a 100 mg/kg dose of Ge-132. The activity of anti-suppressor cells was demonstrated in spleens of mice 2 days after treatment with Ge-132 and reached its peak on day 3. The anti-suppressor cells induced by the compound were of a contrasuppressor T cell-linage, because they were characterized as CD4⁺ CD28⁺ TCR/⁺ Vicia villosa lectin-adherent T cells. These cells produced IFN- but did not produce IL-2, IL-4, IL-6 or IL-10 in their culture fluids. CD4⁺ anti-suppressor T cells induced by Ge-132 may be different from other subsets of CD4⁺ T cells because Th1 and Th2 cells generated in our laboratory did not adhere toVicia villosa lectin-coated petri dishes, and each produced specific cytokines. Th1 cells produced IFN- and IL-2 while Th2 cells produce IL-4 and IL-10 in vitro. These results suggest that Ge-132 may be useful as an inducer of contrasuppressor T cells in immunocompromised individuals bearing suppressor T cells. To eliminate suppressor T cells from immunocompromised hosts may result in improved resistance from various opportunistic infections.
