Cicer arietinum extract ameliorate γ-irradiation disorders via modulation of oxidative/antioxidative pathway.

Ionized radiations trigger thoughtful adverse hazards through multiple organ dysfunctions. Recently, antioxidant-based biodrugs are used to prevent and treat ionizing radiation hazards. The present study aimed to investigate the prospective ameliorative effect of Cicer arietinum extract (CAE) against γ-irradiation and the pathway of this amelioration in male albino rats. Twenty four rats were allocated into four groups; (i) control group, (ii) CAE group in which rats treated with a dosage of 500 mg CAE/kg b.wt, (iii) γ-irradiated group in which rats exposed to 6Gy γ-irradiation, (iv) γ-irradiated+CAE group; rats of this group treated with CAE 1 h post exposure. All rats treated for 21 days. Liver, kidney and femoral bone were rapidly excised and homogenized for the biochemical analysis. Energy dispersive X-ray (EDX) and inductively coupled plasma emission spectrometer (ICP) analyses exhibit that γ-irradiation elicits significant change in the essential trace elements content in liver, kidney, and bone. Further, significant increases in TBARS and H2O2 contents accompanied by significant decreases in GSH, SOD, CAT, and GPx activities in liver, kidney and bone tissues were recorded in the γ-irradiated rats compared to control group. Additionally, marked reduction in the thickness of cortical bone was recorded in rats exposed to γ-irradiation. Conversely, CAE (500 mg/kg b.wt, p.o) administration for 21 days to γ-irradiated rats effectively reverses most of the altered parameters of the γ-irradiated rats. In conclusion, the present findings suggested that CAE is a potential agent that can be used against radiation hazards. This effect may be owing to its antioxidant mechanism, as CAE has an inhibitory effect against hydrogen peroxide (H2O2) and superoxide radical (O2·-) beside its ferric reducing antioxidant power (FRAP). This finding recommended that CAE can be utilized clinically to mitigate ionized radiation-induced hazard effects.
