Values are mean ± SEM; n = 6 rats in each group. Statistical significant variations are compared as follows: CPF, ACEO, ACEO + CPF, VitC, and VitC + CPF treated groups compared to control group; * indicates significantly different when p < 0.05, ** indicates highly significantly different when p < 0.01, CPF group compared to (ACEO + CPF and VitC + CPF) group; ^# indicates significantly different when p < 0.05.
