METHODS: According to adherent + Thy1.1 antibody and complement-purification method, cranium was opened to expose olfactory bulb. Thereafter, two olfactory bulbs were obtained to remove cerebral pia mater, blood capillary, and peripheral tissues; additionally, olfactory nerve layer and olfactory bulb granular layer were sheared into 1-mm3 pieces for extract single-cell suspension. The cells were adjusted at the density of 1×107 /L and incubated with poly-l-lysine-coated culture bottle or culture plate in 5% CO2 incubator at 37 ℃. On the third day, cells were cultured with serum-free DMEM/F12 culture media.

The major results of this proposal are as follows:(1) ABA induces a rapid, substantial accumulation of apoplastic H2O2 in mesophyll and bundle sheath cells of maize leaves, and the accumulation of apoplastic H2O2 is involved in the induction of the chloroplastic and cytosolic antioxidant enzymes.(2) ABA-induced H2O2 production activates a 46 kDa MAPK, which in turn induces the expression of antioxidant genes and up-regulates the activities of antioxidant enzymes. The activation of MAPK also enhances H2O2 production, forming a positive amplification loop.(3) Water stress also induces the activation of a 46 kDa MAPK, which is dependent on the accumulation of ABA and H2O2 production induced by water stress and involved in the up-regulation of the expression and the activities of antioxidant enzymes.(4) ABA-induced H2O2 production mediates NO generation, which in turn activates a 46 kDa MAPK and results in the up-regulation in the expression and the activities of antioxidant enzymes in ABA signaling. NO-independent signaling is also involved in ABA- and H2O2-induced antioxidant defense.

本项目的主要研究结果如下：（1）ABA诱导的H2O2产生主要出现在叶肉细胞与维管束鞘细胞的质外体中，质外体H2O2的积累能够上调叶绿体与细胞溶质中抗氧化酶的活性；（2）ABA诱导的H2O2产生活化一个46kDa的MAPK，由此而导致编码抗氧化防护酶基因的表达与酶活性的上调；而MAPK的活化也能增强H2O2的产生，从而形成一个正的反馈调节环；（3）水分胁迫也能诱导一46kDa MAPK活化，这一MAPK活化依赖于水分胁迫诱导的ABA积累以及H2O2的产生，同时参与水分胁迫诱导的抗氧化防护基因的表达与抗氧化酶活性的上调；（4）ABA诱导一个依赖于H2O2的NO产生，NO活化一个46kDa的MAPK，从而导致抗氧化防护基因的表达以及抗氧化酶活性的上调；同时一个不依赖于NO的信号转导途径也存在于ABA诱导的抗氧化防护过程中。

CD8~+ cell is the main T lymphocyte subset in spleen, and B lymphocyte mainly is IgG~+ cell, moreover the amount of these B lymphocytes could exceed CD3~+ T lymphocyte subset after 7 days. CD8~+ cell is the main T lymphocyte subset in tonsil of appendix, and B lymphocyte is IgM~+ cell, and the amount could exceed CD3~+ T lymphocytes after 35 days. After 21 days, B lymphocytes in esophago tonsil are the main IgA~+ cells and the amount exceeds CD3~+ lymphocytes. The amount of CD4~+ lymphocytes is more than CD8+ lymphocytes.4. CD3~+、CD4~+ and CD8~+ T lymphocytes in spleen mainly distribute in periarterial lymphoid sheath. However IgM~+、IgG~+ and IgA~+ cells mainly distribute in ellipsoid periarterial lymphoid sheath and germinal center. T lymphocytes in appendix tonsil mainly distribute in middle and inferior part of mucous and the B lymphocytes mainly in middle and mucous between 4~7 days. Whereafter T, B lymphocytes equably distribute in mucous. CD4~+ cells arrange tightly and mainly occupy the central part in aggregates of T lymphocytes in esophago tonsil and CD8~+ lymphocytes mainly distribute in periphery. Meanwhile B lymphocytes encircle the periphery of aggregates of T lymphocytes. The aggregates of B lymphocytes is mainly the germinal center with lots of IgM~+、IgG~+ and IgA~+ cells. Meanwihle T lymphocytes encircle the periphery of aggregates of B lymphocytes.5. There is an intimate relationship between the development of tissue structure of peripheral immune organs and lymphcytopoiesis.
