The profile of liver CYP450 induction by DEX in male rat After 4 daily i.p. administering of 0,25, 50 and lOOmg/kg/d DEX in male Wistar rat, it was determined the total CYP450 content, the mRNA and protein expression levels of CYP3A1, CYP3A2 and CYP2B1/2, and the ERD (CYP3A catalytic activity), PROD (CYP2B catalytic activity) and BROD (total CYP450 catalytic activity) in livers.

DEX对雄性大鼠肝脏CYP450的诱导效应雄性Wistar大鼠腹注0、25、50和100mg DEX/kg/d诱导处理4天后，测定大鼠肝脏总CYP450含量，CYP3A1、CYP3A2和CYP2B1/2的mRNA及蛋白表达水平，肝脏红酶素脱甲基酶(ERD，CYP3A活性)，苄氧基试卤灵脱乙基酶(PROD，CYP2B活性)，苯氧基试卤灵脱乙基酶(BROD，总CYP450活性)，结果表明，CYP450含量、ERD、PROD和BROD在DEX多次诱导后都有升高，CYP3A1 mRNA表达水平、蛋白含量和酶活性有明显的升高，剂量效应关系明显；CYP3A2蛋白也有明显升高，而其mRNA表达水平却没有变化，提示CYP3A1和CYP3A2的诱导机制可能不同。

The research aimed to confirm the suitable hormone kinds and level for rooting induction of bulblet in tissue culture seedlings of narcissus.

［目的］确定水仙组培苗小鳞茎生根诱导的适宜激素种类和水平。

Using the tissue cultured bulblet of narcissus cultivar Fortissimo as tested materials, with 1/2MS as the basic medium, 4 conch, of NAA and IBA including 1.0, 0.5, 0.1 and 0.05 mg/L were set up to study the effects of hormone on rooting induction of tissue culture seedlings in narcissus.

方法］以水仙栽培品种Fortissimo的组织培养小鳞茎为试验材料，以1/2MS为基本培养基，设计1.0、0.5、0.1，0.05mg/L 4个NAA、IBA浓度，研究激素对水仙组培苗生根诱导的影响。

The results showed that NAA at low concentrations 0.1~0.2 mgL^(-1 was more beneficial for root induction, the rate of rooting was up to 100%. 1/4MS was more suitable to deal with the plantlet rooting and form small bulb. The optimal ratio of IBA and AC for rooting was 2.0 mgL^(-1) IBA+0.1%AC. The in vitro growth of plantlets were the strongest, and survival rate was 100% after incubating at 4℃ for 4 weeks when the diameter of bulblet was ≥9 mm.

结果显示；低浓度的NAA0.1~02mgL^(-1有利于根的诱导；生根率均达100%；大量元素1/4MS处理更适合试管苗的生根和小鳞茎形成；"IBA+AC"处理最佳组合是2.0mgL^(-1) IBA+0.1%AC；鳞茎直径≥9mm的试管苗去顶4℃低温冷藏4周；移栽后喷施1/2MS营养液；长势最好；成活率达到100%。
