In order to study the relation of cytochrome P-450 with the protective action of SY-801 and SY-640 against 〓-induced UDS and 3H-BP binding to nuclear DNA, the effects of SY-801 and SY-640 on liver microsomal cytochrome P-450 were studied in mice. The results indicated that the liver microsomal cytochrome P-450 concentration and aminopyrine demethylase activity were significantly increased in mice pretreated with SY-801 150mg/kg or SY-640 150 mg/kg once daily for three days.

And the antioxidant enzymes were also activated. We found that there was some signaling pathway within the damaged plant and interplant. Diphenylene iodonium, an inhibitor of NADPH oxidase, could significantly inhibit H2O2 burst and enzymes activities that mediated by herbivore-infested. H2O2 has also been proved to play the signal role in defensive response.

茉莉酸信号传导途径在植物防御反应中有着重要的作用，对植株用茉莉酸甲酯熏蒸后，可诱导植株产生与昆虫取食类似的反应--叶片过氧化氢含量有明显的提高，同时对POD、PPO、PAL等直接防御物质有显著的诱导作用，进而证明了茉莉酸甲酯是伤信息在植株间传递的报警信号分子之一。

The "regulable osteoinduction microcirculation/microenvironment system in vivo" has characteristics as follows: the culture conditions are controlled. For example, the release of a variety of growth factors can be controlled stably and quantitatively at bone defect site. Early nutrition and revascularization in the center of tissue-engineered bone can be effectively solved; some shortcomings resulted from construction of tissue-engineered bone in vivo, including secondary injury, high level technical requirements, and complex operation, can be avoided; vascularization and osteogenesis can be constructed simultaneously; simple safe and efficient operation.
