| Summary: | Atrazine is an herbicide associated with respiratory disorders and the presence of oxidative stress, which can be reversed by association with antioxidant compounds, such as vitamin E. This study aimed to investigate the impact of atrazine (AZ) on the male rat diaphragm muscle and the attenuating effects of vitamin E. Fifty-two male rats were received for 28 days by gavage (n = 13/group): C (control), corn oil; AZ (100 mg/kg); AZE, AZ (100 mg/kg) and vitamin E (200 mg/kg); E, vitamin E (200 mg/kg). Both oxidative stress analysis and morphological analysis of the diaphragm muscle, neuromuscular junction (NMJ), and phrenic nerve were performed. Exposure to AZ caused oxidative stress in muscle fibers, as evidenced by the highest lipid hydroperoxide, and hydrophilic antioxidant capacity values in the AZ group. However, in the AZE group, these values were like those of the C group. The area and diameter of the muscle fiber were only larger in the E group. Exposure to AZ caused oxidative stress in the diaphragm muscle, but vitamin E attenuated these alterations and protected muscle fibers from the oxidative damage. Therefore, vitamin E may serve as a useful attenuating agent against AZ-induced oxidative stress in the skeletal muscle. |
