This paper precisely conducts the special topic research in view of some important technologies of the digitized control module.(1) AC motor control circuit of PAN/TILT is designed ,which speed is controlled by AT89C51 MCU. DC motor control circuit of LENS is designed too.(2) The hardware and software of automatic temperature control is designed, which used in camera protect box without A/D IC. A kind of single wire communication IC is used in the circuit. So, the program is given.(3) A method of video switch without picture shock is discussed in this paper, and 16x8 video switch circuit is designed. AT89C51 can carry out time sequence logical control with the sync signals by request..(4) The module of real-time clock is designed, in which, LCM is used, a kind of three-wire communication IC is used too.

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。
