本次动物实验，主要探讨黑木耳的抗脂质过氧化作用。４５只新西兰白兔随机分为正常组，胆固醇组和黑木耳加胆固醇组，实验期为三个月。实验期间除测定血清总胆固醇（ＴＣ），血清β脂旦白（β－Ｌｐ）和动脉硬化程度以外，还测定各组动物实验前后血清中脂质过氧化产物丙二醛（ＭＤＡ）含量的变化，用荧光法测定主动脉弓和腹主动脉组织中超氧化物歧化酶（ＳＯＤ）的活性。实验结果表明：黑木耳除具有降血脂和抗动脉粥样硬化效果外，还具有抗脂质过氧化作用。脂质过氧化与衰老有密切关系。高脂血症和动脉粥样硬化均为老年人易患疾病。故老年人经常食用黑木耳将有利于防治高脂血症和冠心病及延缓衰老等作用。黑木耳可作为老年人的保健食品加以推广。
The animal experiments, the main black fungus anti-lipid peroxidation. 45 New Zealand white rabbits were randomly divided into normal group, cholesterol group and black fungus plus cholesterol group, the experimental period was three months. During the experiment, in addition to the determination of serum total cholesterol (TC), serum β-lipoprotein (β-Lp) and the degree of atherosclerosis, the change of serum lipid peroxidation product malondialdehyde (MDA) , And the activity of superoxide dismutase (SOD) in the aortic arch and abdominal aorta was measured by fluorescence method. Experimental results show that: black fungus in addition to lipid-lowering and anti-atherosclerotic effect, but also has anti-lipid peroxidation. Lipid peroxidation and aging are closely related. Hyperlipidemia and atherosclerosis are susceptible to the elderly. Therefore, the elderly often eat black fungus will help prevent hyperlipidemia and coronary heart disease and delay the role of aging. Black fungus can be used as an elder’s health food to be promoted.
