Abstract: 　Objective To observe the dynamic changes in the contents of amino acid(AA),glucose(Gluc) and triglyceride(TG) in the culture medium containing adult Schistosoma japonicum .Methods The contents of AA, Gluc and TG in the culture medium during the incubation period from d 0 to 6 d were detected by amino acid automatic analyzer and automatic biochemical analyzer.Results The contents of Arg,Thr,Met,and Lys and Gluc were reduced, Asp and Ala increased apparently.Concluasion Increasing the levels of Arg,Thr,Met Lys and Gluc,reducing the levels of Asp and Ala,and changing the culture medium in time might be in favor of the in vitro cultivation of S japonicum .

Key words: adult Schistosoma japonicum, cell culture, amino acid, glucose, triglyceride
