Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

结果表明：棉花植株水浸提液对萝卜、白菜、莴苣、油菜、稗草、狗尾草、苘麻均具有化感效应，随着作用浓度增加，抑制效应逐渐加强；棉花茎叶和根系水浸提液对棉花种子萌发、幼苗生长、幼苗根系活力、根系酶活性有抑制或促进作用，当茎叶浸提液浓度为0.02 gmL^(-1)时，棉花根长、苗高、侧根数、干重分别比对照增加10.3%、3.1%、22.9%和2.4%，当浓度为0.1 gmL^(-1)时，上述指标与对照相比分别降低34.4%、39.2%、40.6%和19.0%，而根系活力、SOD活性比对照降低38.2%、36.7%，POD活性、MDA含量较对照增加52.3%和36.5%，不同浓度棉花植株水浸提液对棉花生长呈现&低促高抑&的规律，且茎叶浸提液作用效应大于根系浸提液。

Fluorogenic and HPLC assays using isolated microsomes showed robust catalytic activity of the prototype CYP 3A4 enzymes, and the values of Vmax and Km were comparable to the published data.

另外，与CYP3A4野生型相比，突变株R162Q，L293P，M445T和P467S代谢底物的能力没有显著改变，而T185S，F189S和S222P的活力均有不同程度的下降，其中F189S的活力最低，达到CYP3A4野生株的1/10。

Exgenous ABA could inhibit germinationof high vigor seeds at low concentration(5ppm).The germinative power,percentage germinationand vigor index were significantly reduced.

外源ABA对高活力种子萌发有显著抑制作用，在低浓度（5ppm）时，种子发芽势、发芽率及活力指数都显著下降；当浓度达40ppm时，则完全抑制种子萌发。

objective to search the factors of liver injury via the anit-induced liver injury in rats.methods male sprague-dawley rats,were divided into 4 groups,data were analyzed using a completely randmized factorial anova and linear correlation.results after anit intoxication,the necrosis of hepatic cell and neutrophil infiltration im periportal region of the liver were observed in liver setions.jinshisan can reduce the alt,the tbil.pla2 correlated positively with alt、akp and tbil.conclusion the severity of anit-induced liver injury correlated positively with the pla2.jinshisan can protect against the rat anit-induced liver injury.

目的 拟通过对α－萘异硫氰酸酯诱导大鼠肝损伤发病机理的探讨，对引起肝损伤的因素进行系统的研究。方法选择s-d大鼠，雄性，随机分4组，检测数据以平均值±标准差表示，采用方差分析，相关分析进行统计学处理。结果s-d大鼠经anit染毒后，病理切片显示肝损伤明显，汇管区有大量中性粒细胞浸润。经金石散及地塞米松治疗后，生化指标均有所下降，中药金石散优于地塞米松，血生化指标与pla2活性相关分析显示，呈正相关。结论 anit诱导的肝毒性损伤程度与肝组织匀浆pla2活力呈正相关，应用抑制剂降低pla2活力，肝损伤程度也减轻，中药金石散具有降低pla2活性，减轻肝毒性损伤。
