The effect of administration of the antioxidants ascorbic acid and alpha-tocopherol was also studied.
120 rats were divided into the following groups (each group = 5 rats): Six groups served as control group, six groups were microwave exposed, six groups were treated with ascorbic acid, and six groups were treated with alpha-tocopherol (both four days before exposure). The lipid peroxidation was monitored for a period of 8 weeks post irradiation.

Animals were divided into the following groups: i) microwave exposure ii) microwave exposure + 1 mg/kg ascorbic acid - 4 days before exposure iii) microwave exposure + 1 mg/kg alpha-tocopherol - 4 days before exposure iv) control

The microwave exposure caused an increase in the lipid peroxidation within the first 24 hours after exposure, and then gradually reduced to the value of the control group after about one week. Ascorbic acid and alpha-tocopherol administration caused a decrease of the control value of the lipid peroxidation within the first week after irradiation.
The data demonstrated that microwave exposure caused significant increase in the lipid peroxidation status and there were protective effects of the antioxidants ascorbic acid and alpha-tocopherol.
