Nicotine exposure during pregnancy induces oxidative stress and leads to behavioral alterations in early childhood and young adulthood. The current study aimed to investigate the possible protective effects of green tea () against perinatal nicotine-induced behavioral alterations and oxidative stress in mice newborns. Pregnant mice received 50 mg/kg on gestational day 1 (PD1) to postnatal day 15 (D15) and were subcutaneously injected with 0.25 mg/kg nicotine from PD12 to D15. Nicotine-exposed newborns showed significant delay in eye opening and hair appearance and declined body weight at birth and at D21. Nicotine induced neuromotor alterations in both male and female newborns evidenced by the suppressed righting, rotating, and cliff avoidance reflexes. Nicotine-exposed newborns exhibited declined memory, learning, and equilibrium capabilities, as well as marked anxiety behavior. significantly improved the physical development, neuromotor maturation, and behavioral performance in nicotine-exposed male and female newborns. In addition, prevented nicotine-induced tissue injury and lipid peroxidation and enhanced antioxidant defenses in the cerebellum and medulla oblongata of male and female newborns. In conclusion, this study shows that confers protective effects against perinatal nicotine-induced neurobehavioral alterations, tissue injury, and oxidative stress in mice newborns.
孕期接触尼古丁会引发氧化应激,并导致幼儿期和青年期的行为改变。本研究旨在探讨绿茶对围产期尼古丁诱导的新生小鼠行为改变和氧化应激的可能保护作用。怀孕小鼠在妊娠第1天(PD1)至出生后第15天(D15)接受50毫克/千克[绿茶成分未给出英文,无法准确翻译],并从PD12至D15皮下注射0.25毫克/千克尼古丁。暴露于尼古丁的新生小鼠睁眼和毛发出现明显延迟,出生时及D21时体重下降。尼古丁诱导了雄性和雌性新生小鼠的神经运动改变,表现为翻正、旋转和悬崖回避反射受到抑制。暴露于尼古丁的新生小鼠表现出记忆、学习和平衡能力下降,以及明显的焦虑行为。[绿茶成分未给出英文,无法准确翻译]显著改善了暴露于尼古丁的雄性和雌性新生小鼠的身体发育、神经运动成熟和行为表现。此外,[绿茶成分未给出英文,无法准确翻译]预防了尼古丁诱导的组织损伤和脂质过氧化,并增强了雄性和雌性新生小鼠小脑和延髓中的抗氧化防御。总之,本研究表明[绿茶成分未给出英文,无法准确翻译]对围产期尼古丁诱导的新生小鼠神经行为改变、组织损伤和氧化应激具有保护作用。
