ABSTRACT
The paper describes the endemic situation of schistosomiasis japonica in Fanhu village, Poyang Lake region, China and the effect of the strategy of combining annual mass chemotherapy with health education on schistosomiasis control in the community. The results showed that the prevalence of infection with schistosome reduced form 26.0% in 1992 to 10.7% in 1994, the intensity of infection in residents decreased from 1.92 in 1992 to 0.55 in 1994 and the condition of hepatomegaly, splenomegaly and liver fibrosis also improved after chemotherapy in the individuals in the case prospective study. Moreover, the future strategies of schistosomiasis control in this area have been suggested according to the transmission of schistosomiasis in the lake region and the effect of anti-schistosomiasis control indifferent populations.

An anti-idiotypic antibody approach was used to identify chloroplast and mitochondrial protein component(s) which interact with the corresponding signal sequence. The proteins thus identified can be operationally defined as receptor(s) for import of proteins into chloroplasts and mitochondria. The import receptor(s) was found in "contact sites" between the outer and inner membrane of chloroplast envelope or of mitochondria.
