The results showed that precursor feeding (phenylanine, sodium acetate and benzamide) and mixed sugar as production medium resulted in significant increase of taxol production not only in the one-liquid-phase cultures of Taxus chinensis var. mairei but also in the two-liquid-phase cultures. And the integrated function of precursor feeding and mixed sugar in the two-liquid-phase cultures gave more significant increase of taxol production significant increase of taxol production, which was four times more than that of the control (the one-liquid-phase culture without precursors and mixed sugar).

结果表明前体饲喂（苯丙氨酸，醋酸钠和苯甲酰胺）和蔗糖与麦芽糖配伍作为生产培养基糖源不仅对红豆杉细胞悬浮培养，而且对其两液相培养的紫杉醇产量提高均有明显的促进作用，与对照组相比，在南方红豆杉细胞两液相培养中，采用前体饲喂和蔗糖与麦芽糖配伍作为生产培养基糖源，紫杉醇产量提高4倍多。

Attempts in part I of the dissertation were to develop microemulsion systems using medium chain triglyceride, Captex 300, deionized water (H2O), and TPGS as surfactant for the oral delivery of protein drugs or poorly water soluble drugs. Pseudo-ternary phase diagrams were constructed to elucidate the phase behavior of systems composed of medium-chain triglyceride and water with TPGS as main surfactant, polysorbates (Tween 20, Tween 40, Tween 60 and Tween 80) as adjuvant surfactants, and polyethylene glycols (PEG 400 and PEG 600) and polyols (ethanediol, 1,2-propanediol, 1,3-propanediol, 1,3-butanediol, 1,4-butanediol and glycerin) as cosurfactants.

结果表明，环氧基在固化过程中会参与交联反应，电泳液的稳定性、涂膜的物理性能和耐化学品性能由胺值、缩水甘油酯单体种类、丙烯酸缩水甘油酯含量和封闭型多异氰酸酯用量等因素决定。

In the pretreatment group, Bak Foong Pill extracts were given for 14 daya prior to MPTP. Immunostaining of tyrosine hydroxythase was used to observe the damage of dopamine neurons, and of Bax to detect the protein levels of Bax. High performance liquid chromatography-electrochemical detection was used to investigate the contents of DA and its metabolites dihydroxy-phenylacetic acid and homovanillic in the Str.
