Applied with test of potted plant and measurement absorbency for study physiological response of activity of cell defense enzymes and lipid peroxidation of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of superoxide dismutase, catalase, antioxidant, malondialdehyde and the rate of superoxide anion(-O2) generating are mensurated under normal water condition while soil water content is 70% and light water stress while soil water content is 55% to 60% and medium water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of contents of SOD,CAT,AsA,MDA are mighty notable difference. The rate of -O2 generating is notable difference within families. The rate of -O2 generating is mighty notable difference within water grades.

为研究湿地松优良半同胞家系保护酶及脂质过氧化作用对水分逆境的生理响应，采用盆栽试验和吸光度测定结合的方法，以普通湿地松种子为对照，测定了七个湿地松半同胞家系在正常水分状态（土壤相对含水量为70%）、弱度水分胁迫（土壤相对含水量为55%~60%）、中度水分胁迫（土壤相对含水量为35%~40%）和强度水分胁迫（土壤相对含水量为20%~25%）条件下的SOD、CAT、AsA、MDA的含量和-O2产生速率，研究结果表明：无论是不同水分梯度还是不同家系水平，SOD、CAT、AsA活性和MDA含量的差异均达极显著水平，不同家系水平间-O2产生速率有显著差异，不同水分梯度间-O2产生速率差异达极显著水平。

Objective To investigate the effects of AA-861, the specific inhibitor of 5-lipoxygenase (5-LO), on the activation, proliferation and gene expression of kupffer cell and hepatic stellate cell.

目的 探讨5-脂氧合酶（5-LO）特异性抑制剂 AA-861对肝枯否细胞和星状细胞的活化、增殖和基因表达的影响。

For the purpose of constructing mammary gland specific expressional vector, we use the updream regulation sequence of bovine BLG to regulate lacS gene to express in mammary gland. Positive clone cells are selected and purified by the expression Neo gene and report gene EGFP. So the cells can be used as sources to create transgenic animals by nuclear transfer techniques.
