Three groups of female Wistar rats were treated with 0.25%, 1% and 4% of NaMBS in their drinking water for 90 days. An immunization protocol was conducted during the experiment. Mortality, comportmental and weight modifications, and food and water consumption were recorded. At the end of the experiment, the control and experiment rats were killed, and their blood and organs were removed. Immunoglobulin levels were evaluated;biochemical and hematological parameters were investigated. Our results showed that the administration of NaMBS at 1% and 4% had significant effects on body weight, food and water consumed. There was an increase in biochemical parameters (calcium, urea, creatinine, uric acid, transaminases) and decrease immunoglobulin levels. The hematology revealed a decrease in red blood cells and hemoglobin, as well as leucocytosis. Physiological study showed enlarged spleen, kidney, liver and stomach. In light of our results, we can conclude that subchronic intake of NaMBS 1% and 4% seems to alter immune function, biochemical, hematological and physiological para-meters in Wistar rats.展开更多
