  6. 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

  7. In this paper we studied the intercalation behavior of a new host matrix of x = l of zirconium proline - n - mtthyl phosphonate - phosphate ( a - zpmpp ), we successfully introduced butylamine heptylamine decanylamine ethanolamine diethylenetriamine ( 2e3a ) triethyleneteriamine ( 3e4a ) and tetrathyleneoctamine ( 4e5a ) guest molecules into a - zpmpp interlayer space. the intercalation complex were characterized by ir spectrum x - ray diffraction and tg - dsc thermal analysis, it has been found that a - zpmpp possess different intercalation behavior from a - zrp. because of the bulk of proline group, it affected the amount of guest molecule, mono - alkylamine form mono - molecule layer in the interlayer space, butylamine, decanylamine and ethanolamine form mono - layer and the carbon chain form 90 degree ordered assembly with the zirconium floor of a - zpmpp, every host molecule absorbed 0. 5 guest molecule

    本文報道首次以x ? l的層狀(脯氨十一甲基磷一磷氫)鉛( a zpmpp )為主體底物,成功地將客體分子:胺、慶胺、癸胺、乙醇胺、二乙烯三股、三乙烯四胺、四乙烯五股插入層狀化合物a zpmpp的層間,通過紅外光譜( ir ) 、 x射線衍射( xrd ) 、熱重分析( tg dsc )等手段對插層復合物進行結構表徵,結果表明: x ? l的層狀(脯氨件一甲基磷一磷氫)鉛具有不同於無機磷結的插層性能,由於層間脯氨基團的體積較大,影響客體分子進入的數量,胺分子在層板間取單層排列。
