Abstract:
The most suitable antigenic frozen sections are the sections of infected mice liver and adult worm of Schistosoma japonicum at 7th week and 6th week after infection respectively; the most suitable thickness of section is 7?m. The antigenicity of liver tissue-egg frozen section(TEFS) is markedly higher than that of adult worm frozen sectin(AWFS) and of liver tissue-egg paraffin embedded section.TEFS, as antigen, is considered to be of high sensitivity(96.7%), high specificity (98.7%) and lower cross reaction rates(0~3.3%) in IEST for diagnosis of schistosomiasis. The sensitivity of TEFS-IEST ig markedly higher than that of AWFS-IEST and that of COPT. The main advantages of TEFS-IEST are lower cost of the antigen, high sensitivity and rapid yield of results.
