Abstract
Potassium bromate (KBrO3) is widely used as a food additive and is a major water disinfection byproduct. The present study reports the side effects of KBrO3 administration in Swiss mice. Animals were randomly divided into three groups: control, low dose KBrO3 (100 mg/kg/day) and high dose KBrO3 (200 mg/kg/day) groups. Administration of KBrO3 led to decreased white blood corpuscles (WBCs), red blood corpuscles (RBCs) and platelets count in the animals of both the high and the low dose groups. Altered lipid profile represented as low density lipoprotein (LDL), high density lipoprotein (HDL) and cholesterol levels were observed in plasma samples of both KBrO3 treated groups of mice. Also, an increased plasma level of LDH was detected in both KBrO3 treated groups. Histological investigations showed impaired renal and hepatic histology that was concomitant with increased plasma Creatinine level in both of KBrO3-treated groups. Nevertheless, decreased glutathione (GSH) level in both renal and hepatic tissue of mice after KBrO3 intake was detected. These results show that KBrO3 has serious damaging effects and therefore, its use should be avoided. (C) 2017 The Authors. Production and hosting by Elsevier B.V. on behalf of King Saud University.
