摘要:目的 探讨傣药豆腐渣果树皮和果实95%乙醇提取物对酒精引起的氧化应激损伤的抗氧化应激及抗炎活性。方法 采用采用56度北京红星二锅头白酒,以0.05mL/10 g.d给KM种小鼠连续灌胃4周,于模型复制的第2周开始,动物在造模的同时分别给予豆腐渣果树皮和果实95%乙醇提取物,连续给予3周,末次给药后,处死动物,检测动物血清中MDA、SOD、TNF-α的含量及脑匀浆中MDA、SOD的含量。结果 与正常组比较,模型组小鼠给予白酒后第4周即出现血清和脑组织中SOD水平明显下降(P<0.01),MDA水平明显升高(P<0.01),血清中炎症因子TNF-α水平明显升高(P<0.01)。与模型组相比,给予豆腐渣果树皮和果实的醇提取物3周后,均可降低血清中MDA水平和TNF-α水平(P<0.05),并可升高血清和脑中SOD水平(P<0.05)。结论 豆腐渣果树皮和果实的95%乙醇提取物可减轻酒精引起的氧化应激损伤及炎症因子释放。

【Abstract】Objective: To study the anti-oxidative stress and anti-inflammatory activities of the 95% ethanol extracts from the bark and fruit of Helicia erratica Hook in Dai medicine on alcohol-induced oxidative stress damage. Methods: 56% degree of Beijing Hongxing Erguotou Liquor were used to give KM mice intragastrically with 0.05mL/10 god for 4 consecutive weeks. Starting from the second week of model replication, the animals were given the 95% ethanol extracts from the bark and fruit of Helicia erratica Hook for 3 weeks at the same time as the model was created. After the last administration, the animals were sacrificed to detect the contents of MDA, SOD, and TNF-α in the animal serum and the contents of MDA and SOD in the brain homogenate. Results: Compared with the normal group, the SOD level in serum and brain tissue of the model group decreased significantly (P<0.01), the MDA level increased (P<0.01), and the serum inflammatory factor TNF-α level in the 4th week after the administration of liquor was significantly increased (P<0.01). Compared with the model group, after 3 weeks of alcohol extracts from the bark and fruit of Helicia erratica Hook, the levels of MDA and TNF-α in the serum could be reduced (P<0.05), and the levels of SOD in the serum and brain could be increased (P<0.05). Conclusion: The 95% ethanol extract from the bark and fruit of Helicia erratica Hook can reduce the oxidative stress damage and the release of inflammatory factors caused by alcohol.

酒精中毒性腦病(Alcoholic Brain Disease,ABD)是酒精中毒最常见、也是最严重的并发症之一,是由于长时期大量酗酒引起人体营养代谢紊乱,导致中枢神经损害的一类疾病。肝脏是酒精代谢的主要器官,因此既往对酒精造成肝脏损伤的研究较为深入,但近年来的研究表明,过度饮酒可造成脑内炎症甚至是不可逆性脑组织损伤[1],因此ABD的诊治越来越引起人们的关注。
豆腐渣果(深绿山龙眼,Helicia nilagirica Bedd)为山龙眼科Proteaceae山龙眼属Helicia植物,分布于云南产于云南西南部和南部(西双版纳、普洱、保山等地),是傣医用于解除农药中毒、食用野生菌中毒的常用民族药。课题组前期研究发现,豆腐渣果的乙醇提取物具有一定的解酒精中毒作用,并能减轻急性脑损伤动物脑组织炎症反应,故推测豆腐渣果可能对ABD具有潜在活性,本研究拟探讨豆腐渣果不同部位的95%乙醇提取物对酒精诱导的氧化应激反应和炎症因子释放的影响,为研究其对抗ABD的活性提供依据。……
