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

The thermodynamic free energy on mixing and the spinodal equation in ternary homopolymer blends were obtained by making plausible approximation based on flory ' s equation of state theory. because of the non - linear behavior of the spinodal equation, a numerical solution approach was used and succeeded in solving the problem. spinodal of polystyrene ( ps ) / poly ( vinyl methyl ether ) ( pvme ) / poly ( 2, 6 - dimethyl - 1, 4 - phenylene oxide ) ( ppe ) were simulated over a wide temperature range and the calculated result was coincidence with that of the literature
將上述方法用於已知狀態方程參數的二元均聚共混體系聚苯乙烯( ps ) /聚甲基乙烯基醚( pvme ) ,三元均聚共混體系聚苯乙烯( ps ) /聚甲基乙烯基醚( pvme ) /聚2 , 6 -二甲基1 , 4 -苯撐氧( ppe ) ,得到一系列不同溫度下的spinodal相圖,預測結果與文獻報道吻合,在此基礎上進一步研究了聚合物的分子量對體系相行為的影響。 -
