An Experimental Study on Anti-stress Effect of Koumine on Mice / 广州中医药大学学报

ABSTRACT

【Objective】To observe the anti-stress effect of koumine(Kou)on mice.【Methods】Kunming mice were randomized into model group,low-,moderate-and high-dose koumine(1.2,2.4,and 4.8 mg?kg-1?d-1)groups.The treatment lasted 7 days.One hour after last administration,stress tests such as weight-bearing swimming,antihypoxia,high-temperature resistance and low-temperature resistance were carried out.The changes of serum superoxide dismutase(SOD)activity and malondialdehyde(MDA)content were also observed.【Results】During the anti-stress tests,the survival time was prolonged in koumine groups as compared with the model group(P0.05).【Conclusion】Koumine can increase the mice tolerance of weight-bearing swimming,cold and hypoxia,and its anti-stress mechanism may be related to the antilipid peroxidation.
