Figure 4From: Amelioration of azoxymethane induced-carcinogenesis by reducing oxidative stress in rat colon by natural extracts Micronuclei cells counting and cytotoxicity index. (A) Scoring of micronuclei (MN) cells, indicator of genotoxicity, among control, AOM and treated groups. ^Significantly higher as compared to control group. *Significantly lower than AOM-injected group, P < 0.05. (B) The cytotoxicity index (CI) was determined as the ratio of polychromatic erythrocytes (PCE) to normochromatic erythrocytes (NCE), ^Significantly higher as compared to control group. *Significantly lower than AOM-injected group, P < 0.05.Back to article page
