Abstract Title:
Testicular protective effects of ellagic acid on monosodium glutamate-induced testicular structural alterations in male rats.
Abstract:
Ellagic acid (EA) has significant protective and antioxidant effects on several tissues. Monosodium glutamate (MG) is known as a flavor promoter that reversibly influences the male reproductive system. This study aims to assess the ameliorative effect of EA on oxidative stress and testicular damage induced by MG. In total, 48 male rats were included in this study and separated into six groups: control, EA (20 mg/kg), MG (low dose) (17.5 mg/kg), MG (high dose) (60 mg/kg), MG (low dose) combined with EA, and MG (high dose) combined with EA. Testicular antioxidant biomarkers [superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GRx), catalase (CAT), myeloperoxidase (MPO), and xanthine oxidase (XO)] were examined. Testes were examined and scored for histological variation as an indicator of testicular damage following administration of MG alone or in combination with EA. Serum testosterone, inhibin B, 8-hydroxydeoxyguanosine (as a marker of DNA damage), and transmission electron microscope sections of the testis were evaluated, and a comet assay was performed. Results showed that administration of EA combined with MG significantly elevated the levels of enzymatic antioxidants and decreased lipid peroxidation compared with MG treatment alone. EA elevated testosterone hormone levels and thus enhanced male reproductive capacity. It is clear from the data that EA inhibits histological and ultrastructure testicular damage and improves the redox state in male rats.
