In this paper,the Lactate dehydrogenase, malate dehydrogenase,superoxide dis-mutase of five tissues of Carassius auratus gibelio; Cyprinus carpio Linnaeus; Esox americanus Gmelin; Leuciscus waleckii in Dalai Lake were studied by vertical polypropylene gel electrophoresis and the isozyme composion of four kinds of fishes were obtained. Then the analysis of the expressing specify of 3 kinds of isozyme in different tissues and loci were carried on and the genetic base of isozyme system was discussed.

本实验采用垂直板聚丙烯酰胺凝胶的电泳方法对达赉湖的野生鲤鱼、银鲫、狗鱼、东北雅罗鱼的五种组织脏器(肌肉、心脏、肝脏、脑、眼睛)的三种同工酶(苹果酸脱氢酶、乳酸脱氢酶、超氧化物岐化酶)进行了初步研究，获得了达赉湖四种鱼类物种的同工酶谱，在此基础上对同工酶在不同组织的表达差异和基因位点进行分析，探讨其同工酶系统的遗传基础。

The essence of deacetylation reaction of chitin was the hydrolysis of N-alkyl ethanamide.

甲壳质脱乙酰化反应其本质是N-烷基乙酰胺的水解。

Eamamined by fluorescin staining and Giemsa staining, 0.2 mg/L colcemid was considered suitable for inducing high percentage of micronuclei in A9 (neo12) cells, without causing death of a mass of cells.

通过荧光染色和吉姆萨染色分析，结果表明，A9(neo12)细胞经0.2 mg/L秋水仙素酰胺处理48 h后，89﹪的细胞产生微核化，每个细胞平均形成10个微核。

Methods: A model to evaluate lymphocyte proliferation stimulated with a polyclonal activator, concanavalin A, was established by vital dye carboxyl fluorescin diacetate succinmidyl ester labeling technique. Effects of the different doses of anisomycin on the lymphocyte proliferation were estimated by flow cytometry and MTT methods. The propidium iodide labeling technique was applied to assay the effect of the different doses of anisomycin on changes of the lymphocyte cell-cycle stimulated by ConA or by phorbol ester plus Ionomycin. The percentage of the expression level of CD69 and CD25 on the activated lymphocytes was evaluated by fluorescin-conjugated monoclonal antibody double labeling technique.
