Abstract
Diazinon (DZN) has been used for several years in agriculture and urban applications leading to a variety of negative effects on health. Hesperidin (HDN) and garlic oil are naturally occurring compounds present in fruits and vegetables, which have been reported to have antioxidants and anti-inflammatory actions. This study was undertaken to throw light on the modulatory effect of HDN or garlic oil against hemato- and immunotoxicity induced by DZN in Wistar rats. Oral administration of DZN for 30 days resulted in significant decrease in RBCs count, Hb content, Ht value, platelet count, and relative lymphocyte and monocyte counts when compared with control groups. Moreover, DZN reduced significantly the serum total immunoglobulin concentration, hemagglutination titer, quantitative hemolysis of SRBCs, delayed type hypersensitivity, blood mononuclear cell proliferation, phagocytic index and blood T-cell subtypes (CD4+ and CD8+) in comparison with vehicle treatment. Co-administration of HDN or garlic oil, 30 min before DZN was able to normalize most of the hematological and immunological parameters. These results suggested that HDN or garlic oil, the natural antioxidants, can alleviate DZN induced hemato- and immunotoxicity.
