REPORT III. ON PRECIPTIN REACTION FOR SCHISTOSOMIASIS JAPONICA

Abstract

With 3 antigens prepared from adnlt worms, cercariae and eggs, the precipitin test were condncted and the correlation between precipitin reaction and serum protein components were also investigated.
1) Worm antigen gave positive results in mice and rabbits infected 2-3 weeks ago. Cercarial antigen showed positive results in mice and rabbits infected 3 weeks ago. Egg antigen gave a positive results in mice and rabbits infected 5 weeks ago.
2) It is considered that when worm, cercarial and egg test antigens are used, the decrease of albumin as no correlation with precipitin reaction; that When Worm and cercarial test antigen are used, the inerease of α-globulin has correlation with precipitin reaction, that when egg test antigen was used the increase of β-globulinhas correlation with precipitin reaction and that when worm, cercarial and egg test antigens are used, the increase of γ-globulin has correlation with precipitin.rcaction.
