We used rapid diagnostic tests to access the prevalence and intensity of schistosome infection in North Central, Nigeria. A total of 1951 participants were recruited for this study. The participants were screened for S. haematobium infection;haematuria and proteinuria were monitored in the recruited patients with a commercial reagent strip. Of the 1951 participants recruited for the study, 587 were found to be infected. Children aged 0 to 10 years showed the highest levels of haematuria with (100%) specificity. Meanwhile, other age groups (11 - 20, 21 - 30, 31 - 40 and above 40 years) had rates higher than 90%. The degree of haematuria increased with egg intensity. The same was seen in proteinuria, with a percentage of 41.9%. A significant difference (p S. haematobium in rural endemic areas.展开更多

Methods The anticlastogenic activity of redistilled cow's urine distillate was studied in human polymorphonuclear leukocytes (HPNLs) and human peripheral lymphocytes in vitro challenged with manganese dioxide and hexavalent chromium as established genotoxicants and clastogens which could cause induction of DNA strand break, chromosomal aberration and micronucleus. Three different levels of RCUD: 1 μL/mL, 50 μL/mL and 100 μL/mL, were used in the study. Results Manganese dioxide and hexavalent chromium caused statistically significant DNA strand break, chromosomal aberration and micronucleus formation, which could be protected by redisfilled cow's urine distillate. Conclusion The redistilled cow's urine distillate posseses strong anfigenotoxic and antielastogenic properties against HPNLs and HLC treated with Cr^+6 and MnO2. This property is mainly due to the antioxidants present in RCUD.展开更多
