Male C57BL/6 mice infected with Schistosoma japonicum showed marked reduction in serum level of testosterone compared with infection-free male control mice, suggesting that S. japonicum infection suppressed testosterone level in host animals. Potential roles of testosterone in the susceptibility to schistosomiasis were tested by preparing mice in which testosterone levels were artificially manipulated. At 45 days after infection, we observed that male mice with reduced testosterone level showed significantly higher worm burden (p<0.05). The area occupied by granulomas in liver was increased in mice of low circulating testosterone level possibly due to the high worm burden. High level of testosterone also inhibited, to some extent, fecundity of the female parasites. Treatment of infected mice with an inhibitor for testosterone receptor did not alter worm burden, and this suggests that testosterone could have direct effects on the parasites.","PeriodicalId":305785,"journal":{"name":"Japanese Journal of Tropical Medicine and Hygiene","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127238385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Repeated 4 monthly treatment, had significant effect in reducing the worm burden of Ascaris and not the prevalence. As for hookworm infection repeated 4 monthly treatment had significant impact in reducing both prevalence and worm burden in the community. However, repeated 4 monthly treatments had no significant impact in reducing the prevalence and worm burden of Trichuris infection in the community. Trichuris infection should be considered as a continuing infection rather than reinfection because of poor cure rate of albendazole at the onset of the study. Significant and strong predisposition (p < 0.0001) were detected after single and repeated 4 monthly treatment in Ascaris and Trichuris infection but not in hookworm infection. Stratification of data indicated that significant and strong predisposition was also seen in gender. This study concludes that changes in mean egg count per gram (mean EPG) is a sensitive indicator in measuring effect of treatment in an endemic area, and repeated 4 monthly treatments has successfully reduced the worm burden of Ascaris and hookworm infection.
