In addition, chloroform is venomousness which can descend activity of TPS and enhance deposition of impregnant So, taking into account of cost and entironment, Sevag deprotein is carried through 3 tunes.

利用Sevag脱蛋白，加入1/4体积的氯仿和1/16体积的正丁醇，氯仿使蛋白质变性，变性的蛋白质溶于正丁醇中，而多糖不溶于有机层，则可将蛋白质除去。

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。

The chlorin e6 7 and chiorin 11 were oxidized further with osmium oxide in the same oxidization condition to yield bateriochlorin 8 and 12, respectively.

卟吩醛2在碱性条件下转化为卟吩e6三甲酯7，2与烷基溴化镁的格氏反应给出脱镁叶绿酸醇9，选择高钌酸四丙基铵和N-甲基吗啉N-氧化物将3-位羟基氧化成羰基，所生成的卟吩二酮10在酸性条件下脱去甲酸甲酯生成焦脱镁叶绿酸衍生物11，用四氧化锇对7和11实施氧化，则分别转化为细菌卟吩衍生物8和12。

objective to study the effects of berbamine and batiolun on ldh metabolizability in the process of increasing leukocyte.methods enzyme biochemical techniques is used to study the effect of berbamine and batiolˉun in the process of inceasing leukocyte and also to study the effect of ldh metabolizability.results when leukocyte is inhibited by the immune inhibitor cycolophosphamcide,berbamine and batiolun are compared of the effect of ldh activity.conclusionthe study draws the conclusion that both berbamine and batiolun can increase thegranule cell,and they also have some effect of the ldh metabolizability.

目的 研究小檗胺和鲨肝醇升高白细胞作用及对细胞内ldh的代谢的影响。方法采用酶细胞化学方法，对两种药物在治疗由免疫抑制剂环磷酰胺所致的白细胞减少症时，对乳酸脱氢酶活性的影响进行了比较观察。结果小檗胺和鲨肝醇均可升高粒细胞，同时对细胞内ldh的代谢有一定的影响。结论小檗胺和鲨肝醇能使外周血粒细胞增加，可用于治疗多种因素引起的白细胞减少症。
