Effect of ambient temperature on heart rate and tissue magnesium concentration between macrobrachium rosenbergii and macrobrachium nipponese 水温对罗氏沼虾和青虾心率及组织中镁的影响
Effects of lights of five wavelength on the survival rate of post - larval stage of macrobrachium nipponense de haan in the indoor hatchery conditions 5种波长光对日本沼虾人工育苗幼体成活率的影响
The soluble gq was extracted from the retina of the macrobrachium rosenbergi with protein extract and was electophoresised by sds - page 光暗条件下，在3种溶液孵育后的感光细胞中都提取到了42kda的可溶性gq蛋白亚基。
It is believed that these junctions are important to remain the structure of oviduct and keep stable environment in vivo in macrobrachium nipponense 这种连接方式对于保持输卵管壁结构完整性及维持沼虾体内环境稳定有重要作用。
Spermatogenesis macrobrachium rosenbergii during spermatogenesis , chromatins keep on condensing until mid - spermatid stage . the nucleus changes into two forms : fibrous and homogeneous forms 精子发生罗氏沼虾精子发生过程中染色质凝集程度逐渐增大，至精细胞中期凝集程度达到最大。
Our study results indicated : on light adaptation , the ratios of the density of the gold particles in the rhabdom to that in the cytoplasm in macrobrachium rosenbergi photoreceptor cell in high calcium solution , physiological solution and low calcium solution was 21 / 6 、 1 结果显示:光适应组，在高钙溶液、生理溶液和低钙溶液中细胞质与感杆束中胶体金密度的比值是21 / 6 、 17 / 8和13 / 14 。
In this paper , the ultrastructures of compound eyes in blue and red light conditions were firstly studied with the transmission electron microscope in macrobrachium nipponense . the changes of ultrastructural features of rhabdom and cells around were well observed , and were compared thoroughly with the features in full bright light and dark conditions . the functions and significances of related cells structures were discussed during the breakdown and rebuilding of the photoreceptor membrane 本文利用透射电镜技术，首次对红、蓝光照条件下日本沼虾复眼结构，重点是小眼感杆束及其周围细胞超微结构变化作了详尽的观察和研究，并与全光照和全暗条件下的结构特征进行全面比较，探讨相关细胞结构在光感受膜的降解和重新合成过程中的作用和意义。
Several attempts have been made to utilize modern transgenic techniques to express afps genes in frost - susceptible animals and crops to increase their freezing tolerance , and it has been reported that some transgenic organisms do acquire increased cold - resistance . the giant freshwater pravm ( macrobrachium rosenbergii ) is of great economic value and cultured around the world . this prawn has been popular in chinese mainland due to its delicious taste and abundant nutrition since it was introduced here 罗氏沼虾( giantfreshwaterprawn ， macrobrachiumrosenbergii是一具高蛋白、低脂肪、在全球范围内都有养殖记录的重要水产品种，深受人们喜爱，但由于属热带、亚热带种类，对低温的适应能力较差，低于14就会死亡，最低要18才能生长，其不耐低温的特性大大增加了其养殖成本，严重阻碍了罗氏沼虾养殖业的发展。
Spermal ultrastructure the sperm ultrastructure of the macrobrachium rosenbergii and exopalarmon carinicanda holthuis analogical , the whole sperm looks like a inversed umbrella , it has a main body , a spike and a little bit cytoplasm . there are some vesicle exist in the m . rosenbergii sperm nucleus . the relatively length of the spike of the e 各种细胞器数量在精子发生过程中逐渐增多，其中内质网以粗面内质网为主，线粒体于初级精母细胞阶段始出现，膜轮结构在次级精母细胞中出现，精细胞早期的上述细胞器分化成电子密度高的前顶体腔，并逐渐分化形成方形顶体。
二 、 effects of calcium concentration on the membrane - bound gq protein a subunit in the photoreceptor cell of macrobrachium rosenbergi on light adaptation and dark adaptation . the membrane - bound gq a was extracted from the retina of the macrobrachium rosenbergi with protein extract and was electophoresised by sds - page . the percent of the membrane - bound gq a was analyzed by tanon gis gel image disposal system 二、钙离子浓度对光暗适应罗氏沼虾感光细胞膜结合gq蛋白亚基的影响用蛋白质提取液提取膜结合gq蛋白亚基并sds - page电泳，利用tanongis凝胶图像处理系统分析其含量。
