Abstract:
OBJECTIVE:To study the impacts of Zishenyutai pills on the ovarian tissue oxidative damage and Nrf2 protein ex-pression in rats exposed by electromagnetic radiation (EMR). METHODS:Accordiny to their weight,30 SD rats were randomly divided into normal group,radiated group and radiated-treated group with 10 rats in each group. Normal group were not radiated, and other 2 groups were exposed by 900 MHz radiation for 4 h every day;radiated-treated group was given Zishenyutai pills sus-pension [0.25 g intragstrically(medicinal materials)/ml] after radiation;normal group and radiated group were given constant vol-ume of normal saline intragastrically for consecutive 20 d. The rats were killed when they were at the estrum. The Nrf2 proteins ex-pression of ovary were detected by immunohistochemical method,the content of ovary MDA(malondialdehyde),and activity of to-tal superoxide dismutase (T-SOD) and superoxide dismutase (GSH-Px) were detected by biochemical method. RESULTS:Com-pared with the rats in normal group,the Nrf2 protein expression was higher in the rats of the radiated group;the content of ovary MDA was higher and activity of ovary T-SOD and GSH-Px were lower significantly(P<0.05). While compared with the rats in ra-diated group,the Nrf2 protein expression didn’t obviously change in the rats of the radiated-treated group(P>0.05),the content of ovary MDA was lower and activity of ovary T-SOD and GSH-Px were higher significantly (P<0.05). CONCLUSIONS:Zish-enyutai pills can prevent and cure ovary tissue oxidative injury induced by 900 MHz radiation,but have no effect on the expression of Nrf2 protein.
