In the fifth chapter, six compounds formed between nitrogen-containing ligands such as 2, 2'-bipyridyl, isonicotinamide and 1, 4, 8, 11-tetraazacyclotetradecane and the solution cadmium sulfonates such as 1, 5-naphthalenedisulfonate, 2, 6-naphthalenedisulfonate, 4, 4'-bipenyldisulfonate and 4, 4'-penyletherdisulfonate have been synthesized and structurally characterized. Besides, another compound has been synthesized with cadmium carbonate reacting with 1, 5-naphthalenedisulfonate acid.

第五章以2，2'-联吡啶、异烟酰胺和1，4，8，11-四氮杂环十四癸烷与含有Cd〓和1，5-萘二磺酸根离子、2，6-萘二磺酸根离子、4，4'-联苯二磺酸根离子和4，4'-苯醚二磺酸根离子的水溶液反应，合成了六个化合物，另外以1，5-萘二磺酸与碳酸镉反应合成出一个化合物。

The first part reports some new reactions of BNAH, especially the reductive cyclizations of some activated ethylenic compounds to five-membered carbocycles and a sevenmembered enolic ether ring, both of which may be useful in related areas.

详细论文的研究对象是重要的辅酶NADH的化学模型1-苄基-1，4-二氢烟酰胺。论文包括一个对近期该领域进展的综述和三部分工作。

The results indicate that Ca(superscript 2+) and GA3, single or combined application treatments, promote cucumber seed germination treated with P. harmala alkaloid, increase germination rate, germination vigor and index; as well as α-amylase, protease, lipase, isocitratelyase, nicotinamide adenine dinucleotide kinase and Ca(superscript 2+)-ATPase activities; and GA and CaM content in cucumber seeds; but decrease abscisic acid content. The synergistic effects of combined Ca(superscript 2+) and GA3 on increasing GA and decreasing ABA are oberseved compared with Ca(superscript 2+) treatment.

结果表明，Ca(上标 2+)和GA3单一及复合处理可促进骆驼蓬生物碱处理的黄瓜种子的萌发，使黄瓜萌发率、发芽指数和活力指数提高，萌发种子的α-淀粉酶、蛋白酶、脂肪酶和异柠檬酸裂解酶活性及赤霉素和钙调素含量增加，烟酰胺腺嘌呤二核苷酸激酶和Ca(上标 2+)-ATP酶活性增强，脱落酸含量降低；且Ca(上标 2+)和GA3复合处理对GA含量的提高和ABA含量的降低与Ca(上标 2+)单一处理比较呈显著的加成作用。

The IC-BAW is used to pharmaceutical analysis, including determination of nicotinic acid and nicotinamide in multi- vitamin tablet and salicylate in serum of patients. Isonicotinic acid is the transmitant and metabolic products of isoniazid.

三、将IC-BAW应用于药物分析，测定了复合维生素药剂中的烟酸、烟酰胺含量，比常用的化学法和生物学方法简单、快速；也测定了正常人血清和服用阿斯匹林的病人血清中水杨酸含量，结果均与相应的临床方法一致。

The increase in the methylene resonance signal intensity which reflects the alterations in membrane lipids and accordingly in the biophysical and biochemical characteristics of cell membrane during apoptosis was found to be closely associated with nuclear changes as detected by DNA laddering assay and the TUNEL procedure.

在用烟酰胺处理的烟草细胞中，亚甲基信号强度的增加与DNA Ladder几乎同时出现，随诱导时间的延长，亚甲基信号强度也逐渐增大，在24 h亚甲基信号强度增加约2倍。

The glucose-6-phosphate dehydrogenase increased during overw intering,indicating that reduced condition of cell might keep the cell in pr oper function even in cold temperature,and also for cryoprotectant synthesis.The changes in trehalase activity showed that low activity was for keeping higher tre halose content and high activity for removing it in the spring.

越冬期间，体内葡萄糖-6-磷酸脱氢酶活性增高所产生的还原型烟酰胺腺嘌呤二核苷酸磷酸，可为细胞在亚低温状态下发挥正常功能以及体内抗冻保护性物质的合成提供还原动力，同时通过调节体内海藻糖酶活性来维持越冬期间较高含量的海藻糖和移除春季体内累积的过多的海藻糖。

Such cases as hydride ion transfer from reduced nicotinamide coenzymes or the carbanion generated by base abstraction of a substrate proton may lead to attack at the flavinN-5 positions; some nucleophiles, such as the hydrogen peroxide anion, are added on the C-4a position with its frontier orbital.

从减少烟酰胺辅酶或基片基抽象所产生的质子氢离子负离子转移这种情况可能会导致攻击的flavinN - 5的位置；例如过氧化氢负离子一些亲，被添加在C - 4A条位置其前线轨道

Methods Hepatic cells were obtained from fetal rats by means of mechanical separation and hanging-drop culture, and after two days of primary culture, the medium was changed for further cell culture in the presence of 20% fetal bovine serum (containing glucose 25ml/L, mycillin 100 U/ml, pH 7.6), 10 mmol/L nicotinamide, 1 mg/L insulin, affix N2, basic fibroblast growth factor, stem cell factor, epidermal growth factor and leukemia inhibitory factor.
