Development of neuron glucose oxygen deprivation model in evaluation on anoxia endurance function of health food

  • 摘要: 目的 将小鼠大脑皮质神经元的缺糖/缺氧模型用于耐缺氧保健食品的体外评价。方法 采用血清药理学方法制备含牛磺酸复合制剂的小鼠血清,观察其对缺糖缺氧损伤神经元的乳酸脱氢酶(LDH)、超氧化物歧化酶(SOD)活力及细胞生存率的影响,并与小鼠急性脑缺血性缺氧实验结果比较。结果 中、高剂量含牛磺酸复合制剂小鼠血清组LDH活力分别为(5.97±0.85)、(5.68±1.55)U/(g.prot),低于空白血清对照组的(8.27±1.54)U/(g.prot)(P<0.05);低、中、高剂量含牛磺酸复合制剂小鼠血清组SOD活力分别为(6.83±0.65)、(6.95±0.68)、(7.55±0.82)U/(mg.prot),高于空白血清对照组的(5.57±0.89)U/(mg²·prot),细胞生存率分别为90.06%、89.04%、91.92%,高于空白血清对照组的75.74%(P<0.05);牛磺酸复合制剂低、中、高剂量组小鼠急性脑缺血性缺氧存活时间分别为17.3、19.5、18.2 s,比纯水对照组的15.5 s长(P<0.05)。结论 含有某保健食品的小鼠血清对神经元缺糖/缺氧损伤具有保护作用;小鼠大脑皮质神经元的缺糖/缺氧模型可用于保健食品耐缺氧功能的体外评价。

     

    Abstract: Objective To develop a mouse cortical neuron glucose oxygen deprivation model to evalua teanoxia endurance(acute hypoxic ischemic damage)function of health food invitro.Methods Serum pharmacology method was adopted to prepare mouse serum containing taurine.Prmiary cortical neurons from neonate mouse(with in 24hr)were cultured and treated with different concentrations of the serumon the 8th day under the deprivation of oxygen and glucose.Then the contents of lactate dehydrogenase(LDH)and superoxide dismutase(SOD),and the viabitity of the neurons were determined and compared with those of the mice with acute brain hypoxic ischemic damage.Results The LDH levels for moderate and high dose taurine containing serumtreatment groups were 5.97±0.85 and 5 .68±1.55 U/g²prot and significantly lower than that of blank control(8.27±1.54 U/g grot,P<0.05).For low,moderate,and high dose taurine containing serumtreamtent groups,the SOD levels were 6.83±0.65,6.95±0.6,and 7.55±0.82 U/mg grot and the viability of the neurons were 90.66%,89.04%,and 91.92%,which both significantly higher than those of blank serum control(5.57±0.89 U/mg²prot,75.74%;P<0.05 for all).The survival time of the mice in low,mode rate,and high dose taurine complex treatment groups were 173s,19.5s,and 18.2 s and were significantly longer than that of in pure water treamtent group(P<0.05).Conclusion Taurine containing mouse serum has a protective effect on the cultured new born mouse cortical neurons.The results suggest that oxygen/glucose deprivation model of mouse cortical neuron can be used to evaluate the function of health food againstacute hypoxic-ischemic damage invitro.
