补脾益气方对哮喘模型大鼠肺组织核因子Kappa B抑制剂的激酶β表达的影响
摘要
目的:探讨补脾益气方对哮喘模型大鼠肺组织核因子Kappa B(NF-κB)抑制剂的激酶β(the kinase of nuclear fac-tor-kappa B inhibitor β
Objective:To investigate the effect of"TCM prescription for Reinfocing Pi Qi"on regulating the kinase of nuclear factor-kappa B inhibitor β(IKKβ) and the level of interleukin 8(IL-8) in asthmatic rats’lung tis-sue.Method:SPF male wistar rats were randomly divided into normal control group(A)
asthmatic group(B) and therapeutic group of"TCM prescription for reinfocing Pi Qi"(C).Asthmatic model was established via sensitizing and provoking ovalbumin.Rats of the C group were taken medicine ig once a day in 10 g.kg-1 for 21 days.The pro-tein expression level of mRNA of IKKβ in lung tissue was determined by Polymerase Chain Reaction(RT-PCR);the level of interleukin eight(IL-8) was detected in bronchoalveolar lavage fluid(BALF) by enzymes linked immu-nosorbent assay(ELISA).Result:① The expression of mRNA of IKKβ in lung tissue in B group was significantlyhigher than that in A group and C group(P < 0.01 and P < 0.05 respectively).②The expression of protein of IKKβ in lung tissue in B group was significantly higher than that in A group and C group(P < 0.01).③ The level of IL-8 in BALF in B group was significantly higher than that in A group and C group(P < 0.01).Conclusion: "TCM prescription for reinfocing Pi Qi"inhibits IKKβ expression and reduce the level of IL-8.
