Tryptophan peroxidase level and its adaptive activity following administration of tryptophan were estimated in liver of mice infected with Schistosoma japonicum.
Tryptophan peroxidase activity in liver of infected mice was decreased gradually with elapse of time after infection. The degree of adaptive increment of tryptophan peroxidase induced by tryptophan administration increased significantly and reached the maximum on 14th day of infection. Then, it decreased remarkably and showed subnormal level on 28th day of infection.
