Results The activation of NF-κB, proliferation response, and expression of IL-4 and I L-5 mRNA and protein in T lymphocytes stimulated by PMA were significantly hig her than those of their blank control (P.01), while those indexes of T l ymphocytes stimulated by PMA and PDTC simultaneously were significantly lower th an those stimulated by PMA alone (P.01). The apoptotic index of T lympho cytes stimulated with PMA were significantly lower than that of their blank cont rol (P.01), and the apoptotic index of asthmatic guinea pig T lymphocytes stimulated with PMA and PDTC simultaneously were significantly higher than that stimulated by PMA alone (P.01). The significant positive correlations w ere found between the activation of NF-κB and the proliferation (r=0.64, P.001), and the expression of IL-4 and IL-5 mRNA and protein of T lymph ocytes, respectively (r=0.55-0.68, P.001). There was also signific ant negative correlation between the activation of NF-κB and apoptosis of T l ymphocytes (r=0.62, P.001). Conclusions NF-κB may participate in the signal conduction of PKC regulated proliferation, apoptosis and expression of IL-4 and IL-5 of T lymphocytes in asthma.

结果加入PMA培养的哮喘组T淋巴细胞NF-κB的活化、细胞增殖反应、IL-4和IL-5的mRNA和蛋白质的表达均显著高于其空白对照(P.01)，而同时加入PMA和PDTC培养的哮喘组T 淋巴细胞以上指标均显著低于只加入PMA培养的哮喘组T淋巴细胞(P.01)；加入PMA 培养的哮喘组T淋巴细胞的凋亡指数显著低于其空白对照(P.01)，而同时加入PMA 和PDTC培养的哮喘组T淋巴细胞凋亡指数显著高于只加入PMA培养的哮喘组T淋巴细胞(P 。01)。T淋巴细胞NF-κB的活化与增殖反应呈显著正相关(r=0.64，P.00 1)，与IL-4和IL-5的mRNA和蛋白质的表达也均呈显著正相关(r=0.55-0.68，P 。001)，而与凋亡指数呈显著负相关(r=-0.62，P.001)。

The fusion DNA fragments of ag85b-mpb64 and ag85b-mpb64-esat-6 were obtained by PCR andSOE technique. Various DNA vaccines were constructed with the pcDNA3.1: fusion of two genes, and of three genes, bivalent combinations and trivalent combinations(pCA+pCM+pCE6). BALB/c mice were vaccinated with this DNA vaccines.The mice injected withBCG were positive control and the mice injected with pCDNA3.1 and PBS were negative control.The mice were immunized 3 times with 2-wk intervals. The animals in group BCG were only inoculatedsubcutaneously with 1×10~6 CFU BCG at initial vaccination. The serum IgG titers and IgG isotype weredetermined using iELISA coated with M. bovis PPD and rMAE protein expressed and depurated inprokaryotic expression system every week.

The results indicate that:(1)Compare with the comparion, the soil physics character are improved after vegetation restortion , the soil unit weight in cyclobalanopsis glauca, Pinus elliottii, Robinia pseudoacacia , mixed forest and fire slash shrub separatly are 1.525g/cm~3, 1.426 g/cm~3, 1.625 g/cm~3, 1.482 g/cm~3, 1.423 g/cm~3. We can find the soil unit weight in other forest all bigger than the comparion (1.580 g/cm~3) except Robinia pseudoacacia .All these mean forest soil is looser and better capacity for aerated and dank.
