Objective: Our previous studies have revealed that ferulic acid (FA) and sodium ferulate (SF) show significant protective effect on excitotoxicity, the present study was conducted to compare its potential favorable effects of maternal，newborn，and both maternal and newborn intraperitoneal (ip) injection of SF on repair following excitotoxic neuronal damages induced by monosodium glutamate (MSG). Methods: The maternal mice were assigned randomly into seven groups (n = 10 animals in each group): control, 3SF, 20SF, 23SF, MSG, MSG + 3SF, MSG + 20SF, MSG + 23SF groups. The mice at 17 days of pregnancy were treated with or without MSG (2.0 g/kg body weight, ig, once) or/and SF (40 mg/kg body weight, ip), and their offerings treated with or without SF. And then their filial behaviors and hippocampal histopathology were studied. Results: The results showed that maternal, newborn, and both maternal and newborn administration of SF facilitated their filial brain repair, and attenuated the behavioral disorders and histopathological damages of their filial mice in MSG + 3SF, MSG + 20SF, and MSG + 23SF groups in varying degrees. However, the best effects were detected in the filial mice in MSG + 23SF group. Conclusion: Both maternal and newborn administration of SF is conducive to the filial neuronal repair following excitotoxic damages induced by glutamate.
