本实验采用生化方法研究了锯缘青蟹的鳃、肝胰腺和肌肉等不同器官组织中4种类型ATPase活性.结果表明,不同器官组织中同类型ATPase活性各异,Na+K+ ATPase活性由强至弱为鳃>肝胰腺>肌肉.Ca2+ ATPase活性为肌肉>肝胰腺>鳃.Mg2+ ATPase活性为鳃>肌肉>肝胰腺.Ca2+Mg2+ ...ATPase活性则为肌肉>鳃>肝胰腺.同一器官组织中不同类型ATPase活性也有较大的差异,鳃中Na+K+ ATPase活性最大,其余的依次为Mg2+ AT Pase,Ca2+Mg2+ ATPase,Ca2+ ATPase;肝胰腺中Na+K+ ATPase活性最强,其余的依次为Ca2+Mg2+ ATPase,Mg2+ ATPase,Ca2+ ATPase;肌肉中Ca2+Mg2+ ATPase活性最大,其余的依次为Ca2+ ATPase,Na+K+ ATPase,Mg2+ ATPase.此外,锯缘青蟹同一器官组织中同类型ATPase在不同个体间也存在一定差异.不同器官组织中4种类型ATPase活性各异主要与其所执行的生理功能密切相关. 【英文摘要】 The activities of four kinds of ATPases in gill ,hepatopancreas and muscle of mud crab Scylla serata were studied by biochemistry methods. The results showed that the activities of the same ATPase was different in various organs and tissues. Among organs and tissues, the activity of the Na~+K~+-ATPase is gill>hepatopancreas>muscle in descending order; the activity of the Ca~(2+)-ATPase is muscle>hepatopancreas>gill; the activity of the Mg~(2+)-ATPase is gill>muscle>hepatopancreas; the activity of the Ca~(2+...
