Creatine is known to rescue animals following brain damage. Present study was designed to demonstrate the effect of long term (15 week) supplementation of 2% creatine monohydrate (Cr), following neonatal hypoxic ischemic insult, on learning and memory formation in male albino mouse. Albino mice pups were subjected to right common carotid artery ligation followed by 8% hypoxia for 25 minutes. Following weaning, animals were separated and grouped on the basis of dietry supplementation for 15 weeks followed by a battery of neurological tests including Morris water maze, open field and rota rod. It was observed that HI mice fed on 2% Cr for 15 weeks performed better than their littermates mice on normal rodent diet during water maze (learning and memory) and rotating rod (neuro-muscular coordination and balance) test while the results of open field test remained unaffected. It was also observed that Cr treated animals had a reduced brain infarct volume than untreated but this difference did not reached statistical significance. We have also observed an overall increase in body weight in Cr treated mice during the study. Over all our results are indicating that long term Cr supplementation is beneficial for male albino following hypoxic ischemic insult.
已知肌酸能在动物脑损伤后起到挽救作用。本研究旨在证明新生期缺氧缺血性损伤后长期(15周)补充2%一水肌酸(Cr)对雄性白化小鼠学习和记忆形成的影响。将白化小鼠幼崽右侧颈总动脉结扎,然后8%缺氧25分钟。断奶后,根据饮食补充情况将动物分开并分组15周,随后进行一系列神经学测试,包括莫里斯水迷宫、旷场试验和转棒试验。观察到在水迷宫(学习和记忆)和转棒(神经肌肉协调和平衡)试验中,喂食2% Cr 15周的缺氧缺血(HI)小鼠比正常啮齿动物饮食的同窝小鼠表现更好,而旷场试验结果未受影响。还观察到,Cr处理的动物脑梗死体积比未处理的动物小,但这种差异未达到统计学意义。我们还观察到在研究期间,Cr处理的小鼠体重总体增加。总体而言,我们的结果表明,长期补充Cr对缺氧缺血性损伤后的雄性白化小鼠有益。
