The analysis of 1H NMR showed that the succinyl group was successfully conjugated to the amino group of chitosan molecule, and the degree of substitution of Suc-Chi values increased with increasing succinic anhydride/amino mole ratio or reducing the molecular weight of chitosan.

利用壳聚糖和琥珀酰酐反应合成了N-琥珀酰壳聚糖，1H NMR分析表明通过反应可在壳聚糖的侧氨基引入亲水性的羧基，增加琥珀酰酐／氨基的摩尔投料比或者选择分子质量较小的壳聚糖，有利于提高N-琥珀酰壳聚糖的琥珀酰化度。

Methods Thirty adult patients,ASA grade Ⅰ～Ⅱ,scheduled for selective craniotomy,were randomly allocated to receive intravenous infusion of hypertonic saline,succinyl gelatin,or Lactate Ringer's,with 10 cases in each group.

方法30例择期行开颅手术患者，ASAⅠ~Ⅱ级，随机分为高渗盐水组、琥珀酰明胶组和乳酸钠林格氏液组，每组10例，术前缓慢放血，放血量以放血后血细胞比容不低于25%为原则，三组于放血同时分别输入HS、GEL和LR维持正常血压。

A series of cholesterol-bearing O-carboxylmethyl chitosan conjugates with different degrees of substitution of the cholesterol moieties and cholesterol-bearing chitosan were synthesized by the succinyl linkages and characterized by Fourier transform infrared, Proton Nuclear Magnetic Resonance (~1H NMR) and elemental analysis. These hydrophobized chitosan derivatives were amphiphilic in nature and their self-aggregation behavior in aqueous media was evaluated by the fluorescence probe technique.

课题的主要研究内容如下：采用化学的方法合成了不同分子结构、不同取代度的系列胆甾醇基壳聚糖衍生物—胆甾醇基壳聚糖和胆甾醇基-羧甲基壳聚糖，并应用先进的分析手段电位滴定、红外光谱法(IR、核磁共振波谱法等对原料、中间产物以及产物进行了结构表征，衍生物分子中的胆甾醇基取代度(3.2％～12.5％)采用元素分析的方法进行检测。

CoA by strengthening TCA pathway, and the methylmalonyl??CoA is formed from succinyl??CoA by isomerization. Finally, methylmalonyl??CoA can be used as the precursor for the biosynthesis of erythromycin.

餐？戊二酸，再生成琥珀酰CoA，琥珀酰CoA在甲基丙二酰CoA异构酶的作用下生成甲基丙二酰CoA作为红霉素合成的前体。

Self-assembled nanomicelles of N -cholesterol succinyl O -carboxymethyl chitosan were prepared by probe sonication method. The amphiphilic property and the critical micelle concentration of CCMC were determined by fluorescence probe technique; the morphology and the size of CCMC self-assembled nanomicelles were analyzed by transmission electron microscopy and the dynamic laser light scattering.

以 N -胆甾醇琥珀酰基- O -羧甲基壳聚糖(CCMC，胆甾醇基取代度6.9%)为原料，在水溶液中通过探头超声处理制备其自组装凝胶纳米胶束，采用稳态荧光探针法考察临界胶束浓度，并通过透射电镜和动态激光散射仪检测胶束的形态大小。
