Abstract

Lead (Pb) may induce oxidative stress and it can increase the production of free radicals. Lead exposure increased of malondialdehyde (MDA) and reduced super oxide dismutase (SOD) level in mice blood serumand increased lead levels in the liver. It can induce several responses in physiological and bio chemical functions of the body, especially to biochemical of blood components and kidney. The objective of thisresearch was to evaluate the effect of lead acetate exposure on levels of aspartate amino transferase (AST)and alanine aminotransferase (ALT), hemoglobin (Hb) concentration, the number of red blood cells (RBC),also glomeruli kidney in mice. Research was conducted using eighteen male mice, which were grouped into three treatments: P1 (control), P2 (Pb 75 mg/kg BW), P3 (Pb 150 mg/kg BW). The results showed thatto compare the control group, lead exposure significantly shift to enzyme ALT levels, Hb concentration,RBC numbers, percentages of glomeruli (especially in normal, swollen, and contracted glomeruli), Bowman’scapsule diameters, and glomeruli – Bowman’s ratio. On the contrary, the AST levels and glomeruli diameter are insignificantly compared to the control group.
