Malonaldehyde , a marjor product of the peroxidation of polyunsaturated lipids , may play an essential role in the formation of the fluorescent products in lipofuscin - like fluorescent pigments and in the blood viscosity increase . fluorescence and non - enzymatic browning were observed in reactions between ascorbic acid ( asa ) and amino acids ( aa ) as well as in reactions involving asa autoxidation and / or polymerization in the presence of trace amounts of adventitious iron 在同时进行的荧光测定中，我们发现，丙二醛( 20mm )能迅速地降低蛋白溶液的典型荧光( 280nm 350nm ) ，而就此产生在395nm的波长激发下，发射出波长为460nm的荧光，造成蛋白质的变构变性。

Flavonoids such as catechins derived from natural plants , including teas , grapes , citruses , and persimmon etc . have been shown to exert a wide range of antioxidants , serum lipid reduction , ant if lamination and anticancer properties , resulting in deeply research on its " autoxidation and mechanisms of antioxidant activies and in healthy function recognition by scholars of medical science and food nutrition 儿茶素等类黄酮类物质广泛存在于茶叶、葡萄、柑橘、柿等多种天然植物中，它具有抗氧化、降血脂、消炎抗癌等多种功效，其保健功能已得到全世界医学界和食品营养界的公认，国内外很多学者对儿茶素等类黄酮类物质的自动氧化及抗氧化机理进行了详细而深入的研究。

Using cd , cu , zn and cr as experimental toxicants and crucian as experimental creature , we employed the environmental biotechniques ( flame atomic absorption spectrophotometry , the method of improved pyrogallol autoxidation and electron microscopy ) to study the acute toxicity and secure concentrations of heavy metals to crucian ; the accumulation and distribution of mixed heavy metals to fingling crucian ; the activities of superoxide dismutase ( sod ) of gill and liver tissues and the hispathological and ultrastructural change of superfine structure of liver and kidney of crucian after cadmium exposure . through which , we intended to fully and systemically study the toxic influence of heavy metals to fish , and preliminarily discuss the influence of heavy metals pollution to the diversified level of fish such as individual , organ , tissue , cell and molecule . thus we tried to provide scientific evidence to establish preventative management measures , avoid and relieve the harm of heavy metals pollution to aquicolous ecosystem in time 随后以这几种重金属作为实验毒物，以鲫鱼为实验动物，应用环境生物技术、火焰原子吸收分光光度法、邻苯三酚自氧化法、透射电镜等技术研究了重金属cu 、 zn 、 cd和cr对鲫鱼的急性毒性及其安全浓度评价、混合重金属在鲫鱼幼体组织内的积累和分布、 cd对鲫鱼鳃和肝脏中sod活性的影响、 cd对鲫鱼肝细胞和肾细胞超微结构的影响等，全面和系统地研究了水环境中重金属暴露对鱼类的毒性影响，初步探讨了重金属污染对鱼类的个体? ?器官? ?组织? ?细胞? ?分子等各水平层次的影响，为制定渔业生产上预防性的管理措施提供科学依据，及时避免或减轻重金属污染对水生生态系统造成的损害。
