TABLE 1.

Changes in food intake and body weight gain of control and treated rats with chlorpyrifos, Artemisia campestris essential oil (ACEO), vitamin C, and their combination (ACEO + CPF and VitC + CPF).

Parameters and treatments	Food intake (g/rat/d)	Gain weights (%)
Control	18.39 ± 1.33	35.33 ± 1.32
ACEO	19.25 ± 1.67	37.22 ± 2.24
CPF	13.59 ± 1.39**	19.53 ± 1.64**
ACEO + CPF	17.89 ± 3.22##	34.76 ± 2.66##
VitC	18.65 ± 1.28	36.43 ± 1.62
VitC + CPF	18.14 ± 2.29##	34.22 ± 1.39##

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 highly significantly different when p < 0.01, CPF group compared to (ACEO + CPF and VitC + CPF) group: ^## indicates highly significantly different when p < 0.01.
