Different cells,cell density and cell shape lead to comparatively great difference in wood properties and physical mechanical properties, change of wood cells affects change of wood properties including wood quality,wood property and all other aspects,and wood properties decide economic value and directly affect manufacturing and utilization of wood,therefore,the research and analysis on wood cell structure become especially important.

由于树木生长不均匀，使各种树木的木材构造具有多样性，不同细胞体、细胞密度和细胞形状导致了木材材性和物理力学性能存在较大差异，木材细胞的变化影响着木材性质的变化，木材的性质又决定木材经济价值，并直接影响木材的加工和利用，由此对木材细胞结构分析研究就变得尤为重要。

The total proteins from TGIF transfectant and vector control cells were separated by 2D electrophorosis. 760±41 and 680±38 spots were detected in TGIF transfectant and vector control cells respectively. Locus repeat analysis of protein spots showed that the mean deviation in IEF direction in TGIF transfectant and vector control cells were 0.864±0.123 mm and 0.843±0.115 mm respectively whereas the mean deviation in SDS-PAGE direction in these two cells were 0.812±0.109 mm and 1. 125±0.123 mm respectively. So the well-resolved and reproducible 2DE patterns from TGIF transfectant and vector control cells were established.

METHODS: After isolated the PBMCs and blood-plasma from adult human peripheral blood by Ficoll-Hypaque centrifugation, the PBMC culture procedure with or without the self-blood -plasma was applied to polarize T cells in vitro , these cells were polarized by PHA(20 mg/L),non-PHA respectively.

用Ficoll-Hypaque梯度离心法分离出正常成人抗凝外周血单个核细胞和血浆，将PBMC置于含或不含有自身血浆环境中，并在植物血凝素(PHA ，2 0mg L)的刺激下进行培养，培养 2 4、48、72h后收获细胞，分别用双色免疫荧光标记，以流式细胞术对CD4+ T细胞表达表面分子CCR3、CCR5进行分析。结果：CD4+ T细胞受自身血浆和PHA刺激后向Th1 Th2两个方向极化，2 4、48、72h后极化率分别达到(13 2 8± 1 5 9)%(12 70± 1 6 5 )%、(17 19± 1 0 3)%(17 5 0± 1 30 )%、(19 49± 2 87)%(18 5 8± 1 49)%；而只有PHA刺激的极化率很低，两组有显著性差异(P 0 1)；Th1∶Th2之比约等于 1。
