Fig 4. Ameliorative effects of the pre-administration of I. oblongifolia leaf extract (IOLE) on alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin in rats exposed to lead acetate (PbAc) for 5 days.

All results are expressed as the mean ± SEM (n = 7). ^ap<0.05, significant change with respect to Control; ^bp<0.05, significant change with respect to PbAc using Duncan's post hoc test.
