文摘

The snails’ tissues represents an intermediate or secondary host for Schistosoma sporocysts where, germ cells within the secondary sporocyst begin to divide to produce thousands of cercariae capable of infecting humans. The aim of the study was to evaluate the toxicity of sodium fluoride in Schistosoma snails’ tissue homogenates. A total number of 264 different Schistosoma snails were collected from eight drainage water resources and divided into control uninfected and infected snails; where infected snails divided into four group; the first group without any treatment while second, third and fourth groups immersed in 25, 50 and 100 mg sodium fluoride/L during the period of 4 weeks then the snails’ hemolymph and tissue homogenates were prepared to evaluate the snail’ tissue antioxidants, protein content, lipid profile and apoptosis. The results obtained revealed that superoxide dismutase, glutathione-S-transferase, glutathione peroxidase, catalase, reduced glutathione, glutathione reductase levels were decreased while malondialdehyde, protein carbonyl, total protein, albumin, globulin, cholesterol, low density lipoprotein and triglycerides levels were increased in Schistosoma infected snails’ tissues. Schistosoma also induced apoptosis in snails’ tissues homogenates. Sodium fluoride restores all the above parameters to approach the control uninfected snails levels. In conclusion, sodium fluoride inhibits oxidative stress and apoptosis produced in Schistosoma infected snails and consequently it is be useful to be used in Schistosoma infection inhibition where sodium fluoride at higher dose was more effective than the lower two doses.
