Abstract:

This study was conducted to investigate the effect of sodium fluoride on the glutathione antioxidant system of mice testis. Twenty-four 3 weeks old ICR male mice were randomly divided into control group and 3 fluoride groups. The four groups were orally administrated with 0, 25, 50, and 100 mg·L-1 NaF for 60 days. After the exposure treatment, the level of T-AOC, ROS and MDA, the activity of GPx, GST and GR and gene transcription of GPx1, GPx4, GST-mu5 and GR in the testis were detected. The mitochondria, endoplasmic reticulum and Golgi apparatus were observed by electron microscope. Results were as follows: Compared with the control group, the contents of T-AOC was decreased, the contents of ROS and MDA were raised, and the activity of GPx, GST and GR were reduced, and the relative mRNA transcription of GPx1, GPx4, GST-mu5 and GR were down-regulated. It was showed that the antioxidant capacity of testis were decreased and in an obvious oxidative stress state, which related to the decrease of the enzyme activity of glutathione antioxidant system and its related gene transcription.
