RESUMO
OBJECTIVE: Accumulating studies have demonstrated the potential activity of ginger in treating and managing several diseases but little is known about its protective effects against teratogenicity of chemical toxins. Thus, in this study, we have evaluated the protective effect of gingerol fraction (GF) against methyl ethyl ketone (MEK) induced teratogenic effects in newborns of mice. MATERIALS AND METHODS: A total of 30 mature females and fifteen male mice (Mus musculus) weighing 25-30 g were included in this study. The pregnant mice were divided into three groups (10 mice each); control group (GI, mice received normal drinking water; NDW), methyl ethyl ketone (MEK) treated group (GII, received MEK at a dose of 350 mg/kg body weight in NDW), and GF treated group (GIII; mice received GF at a dose of 25 mg/kg in NDR). Histological analysis, cellular oxidative, and antioxidant enzymes, fibrosis, and apoptosis of brain, liver, and kidney tissues were estimated by histological and immunoassay techniques. RESULTS: In this study, the treatment of pregnant female mice with gingerol fractions (GF) at a dose of 25 mg/kg significantly protected all tissues organs of mothers and their offspring against the teratogenic effects induced by MEK at a dose of 350 mg/kg. A significant improvement in cellular antioxidant enzymes GSH, SOD, and peroxidase activities along with a reduction in the initiation of cellular oxidative free radicals (TBARS) was reported in GF treated mice compared to mice intoxicated with MEK (350 mg/kg). In addition, a significant reduction in cellular fibrosis and apoptosis was reported in all tissues of mothers and their offspring's following treatment with GF. HPLC analysis of ginger extracts estimated a set of polyphenolic compounds such [6]-gingerol, [8]-gingerol, [10]-gingerol, and [6]-shogaol which are responsible for the antioxidant, anti-fibrotic, and anti-apoptotic protective effects against teratogenic effects of MEK. CONCLUSIONS: Gingerol fractions (GF) at a dose of 25 mg/kg significantly protected all tissues organs of mothers and their offspring against the teratogenic effects induced by MEK at a dose of 350 mg/kg. The beneficial effects of ginger phenolic compounds; [6]-gingerol, [8]-gingerol, [10]-gingerol, and [6]-shogaol against teratogenic effects of MEK proceeded through their antioxidant, anti-fibrotic, and anti-apoptotic properties.
