中国对虾血细胞中酚氧化酶活力研究 总被引：13，自引：1，他引：13
脊椎动物血淋巴中的酚氧化酶的研究已有大量资料，不少学者［４，７，８］认为黑色素的聚集与昆虫伤口愈合、结节形成及包被作用有联系，而黑色素的聚集则与昆虫血淋巴中的酚氧化酶及其底物相关。程振衡和梁子才［１］他发现在亚洲玉米螟血淋巴中的酚氧化酶可以粘附到酵母菌细胞表面。在水生无脊椎动物中，有关酚氧化酶的研究报道甚少，特别是对虾酚氧化酶的特性研究，还未见到这方面的有关资料。本文报道中国对虾（Ｐｅｎａｅｕｓｃｈｉｎｅｓｉｓ）血淋巴中血细胞内的酚氧化酶的存在及各种因子对其活力特性的影响。１材料与方法１．１实验… 相似文献

无脊椎动物或脊椎动物对外源物质伤害的防御机理,概括地说是对入侵异己物质的识别和反应。无脊椎动物不存在B或T淋巴细胞系统,在体液因子中也没有免疫球蛋白存在。因此,无脊椎动物的防御系统有别于脊椎动物。 相似文献

A solid powder oxygen-releasing agent was developed and tested in prawn culture. Dissolved oxygen (DO) is a basic necessity for aquatic life and is affected by water temperature, climate, plankton, etc. DO variation in culture ponds strongly and consequently affects prawn growth and production output.In summer, when air temperature is high, pond water is polluted (by prawn feed leftovers) and cannot be changed fully and as frequently as necessary; especially at night, when there is no sunlight for photosynthesis with oxygen as a by-product, the DO in pond water can decrease rapidly. Under the above circumstances, the prawns experience serious lack of oxygen before dawn and die in large number. To solve this problem, we developed an oxygen-releasing agent with excellent perform -ance. 相似文献
