Effect of Citrus sinensis peel extract (CSPE), Hespiridin (H) and Omeprazole (OM) on EtOH-induced disturbance in gastric H₂O₂, free iron and calcium levels. Animals were pretreated with various doses of CSPE (100, 200 and 400 mg/kg, p.o.), OM (20 mg/kg, b.w., p.o.), H (50 mg/kg, p.o) or NaCl 9‰

Pretreatment	Free iron (μmol/mg protein)	Calcium (mmol/mg protein)
Control	18.08 ± 1.06	101.69 ± 6.91
EtOH	42.14 ± 2.43*	194.18 ± 16.13*
EtOH + CSPE-100	33.36 ± 1.38**	142.64 ± 9.46**
EtOH + CSPE-200	26.12 ± 1.17**	129.88 ± 7.68**
EtOH + CSPE-400	19.68 ± 1.53**	113.99 ± 9.19**
EtOH +Omeprazole	22.29 ± 1.67**	117.44 ± 14.27**
EtOH + Hesperidin	20.76 ± 1.20**	104.38 ± 13.26**

The data are expressed as mean ± S.E.M. (n = 10) * p < 0.05 compared to control group and ^** p < 0.05 compared to EtOH group
