METHODS: Effect of Rgl and Rhl on the production of IL- 12 p40 protein was detected by ELISA, and the IL- 12 p40 mRNA level of DC was monitored by RT- PCR. Anti - tumor activity of DC- LPAK was detemnined by neutral red staining assay. RESULTS: The results of ELLSA showed that Rgl and Rhl significantly enhanced the production of IL- 12 p40 of DC. Rgl at 1 mg/L and Rhl at 100 mg/L upregulated the IL- 12 p40 mRNA level. Rgl and Rhl enhanced the anti - tumor ability of DC, induced lyrnphokine and PHA activated killer (DC-LPAK) on human papillate tumor cell line. Each dose of Rgl can obviously accelerate the eytotoxity to L929 at the E: T ratio of 5 : 1 (P<0.05,0.01 ), while only Rhl 10 mg/L enhanced the eytotoxity ability of DC- LPAK (P < 0.05). CONCLUSION: Rgl and Rhl enhanced the production of IL-12 p40. This effect may be mediated by the increase in the mRNA level. As a result, Rg1 and Rhl oromote the ability of DC to stimulate the cytotoxitie aetieity of DC - LPAK.展开更多

Geometry optimization and harmonic vibrational frequency calculations have been performed on the AX～U4（）1A1 state of O3 and AX～U4（）2B1 state of O-3. Franck-Condon analyses and spectral simulation were carried out on the first photoelectron band of O-3. The theoretical spectrum obtained by employing CCSD（T）/6-311+G（2d,p） values are in excellent agreement with the observed one. In addition, the equilibrium geometry parameters, re（OO）= 0.135?5±0.000?5 nm and θe（O-O-O） =114.5±0.5°, of the AX～U4（）2B1 state of O-3, are derived by employing an iterative Franck-Condon analysis procedure in the spectral simulation.展开更多

The relativistic corrections to order α 2(a.u.) and the effect of the motion of the center of mass are treated by using first-order perturbation theory. Most of our predicted results are in good agreement with recent results of Yan and Drake, which were obtained by using the wave functions with doubled Hylleraas coordinates. Based on the analysis of the convergence pattern in our calculation, we believe that our predicted value of the δg L-factor for 3 3P state in 4He, 2.914 15×10 -7 , ought to be reasonable and accurate, although there are no corresponding experimental data available in the liteature yet to be compared with.展开更多
