Abstract : the anti - inflammatory effect of n - butanol extract of xanthocerassorbifolia bunge ( bex ) was studied in this paper. the ear edema resulted from dimethyl benzene, paw edema induced by carrageenin, the increase of vascular permeability caused by acetic acid, the chemotaxis of wbc induced by cmc and the weight of cotton granuloma in mice and hind paw edema induced by fresh egg white in rats were inhibited significantly by ig bex daily for 7 days, respectively. the carrageenin - induced paw edema was also inhibited markedly in adrenal - ectomiced mice. no changes in weight of adrenal and the concentration of vitamin c were observed, indicating that the anti - inflammatory effect of bex was not related to pituitary - adrenal system
文摘:文冠木正丁醇提取物對二甲苯致小鼠耳腫脹、蛋清致大鼠足腫脹、角叉菜膠致小鼠足腫脹、醋酸致小鼠腹腔毛細血管通透性增加、小鼠羧甲基纖維素囊中白細胞遊走、小鼠棉球肉芽腫生長均有顯著的抑制作用,同樣劑量下,文冠木正丁醇提取物對角叉菜膠致去雙側腎上腺小鼠足腫脹仍有顯著的抑制作用,且對小鼠腎上腺重量及腎上腺中維生素c的含量沒有明顯影響。In this thesis, the development of emulsion polymerization theory and related new technologies are comprehensively reviewed, and the synthetic technologies of acrylate latex modified by organosilicon both at home and abroad are also reviewed. based on the current development and research in this field, attentions of this study are focused on three ways for preparing novel acrylate latexes modified by organosilicons, that is, 1 ) the acrylate monomers are copolymerized with unsaturated silicons by emulsion copolymerization ; 2 ) a new latex with microphase separation morphology is synthesized, which shows a core - shell structure character ; 3 ) soap - free polymerization is explored for preparing a higher - performance latex using an unsaturated silicon monomer, different acrylates and a reactive emulsifier. by using techniques of delaying addition of organosilicon monomer and a hydrolysis inhibitor, the hydrolysis and condensation of 3 - ( trimethoxysilyl ) propyl methacrylate during polymerization can be effectively prevented, as a result, organosilicon content in the macromolecular chain is increased
