几种外用中药成份对离体人脐静脉内皮细胞增殖的影响

目的:体外观察几种常用外用中药有关成分对血管内皮细胞增殖作用的影响,初步探讨其对创伤愈合的可能作用。方法:采用MTT比色法观察中药人参皂苷Rg1、Rh1、黄芪多糖、鹿茸多肽、川芎嗪、麝香酮、桂皮醛和乳香水提物对人脐静脉内皮细胞(HUVEC)增殖的影响。结果:9.75mg/L-2.5g/L的黄芪多糖对HUVEC未表现出增殖促进作用;1.94mg/L-0.5g/L的人参皂苷Rh1促进HUVEC的增殖(P＜0.05或P＜0.01),31mg/L的人参皂苷Rg1抑制细胞增殖(P＜0.05);1mg/L-0.5g/L的鹿茸多肽明显促进HUVEC的增殖,以10mg/L作用最明显(P＜0.01),桂皮醛2g/L时促进HUVEC的增殖(P＜0.05);1g/L的麝香酮明显抑制HUVEC的增殖(P＜0.01);0.5kg/L-2.5kg/L(生药)乳香水提物明显抑制HUVEC的增殖(P＜0.01),抑制增殖率为35.56%-55.56%。川芎嗪0.125g/L-0.5g/L明显抑制HUVEC的增殖(P＜0.01)。结论:益气温阳药物人参(Rh1)、鹿茸(鹿茸多肽)、肉桂(桂皮醛)促进HUVEC增殖;通络活血药物麝香(麝香酮)、乳香(乳香水提物)、川芎(川芎嗪)抑制HUVEC增殖。

Effects of component of some Chinese herbs on proliferation of human umbilical vein endothelial cells in vitro

AIM: To observe the effects of some component of Chinese herbs for external use on proliferation of human umbilical vein endothelial cells (HUVEC) and investigate the mechanism of promoting tissue repair. METHODS: The method of MTT was used to examine the effects of Rg1, Rh1, perlolyrine, cinnamyl aldehyde, muscone, astragalus polysaccharin (APS), velver antler polypeptide (VAP) and soluble extract of boswellia carterii birdw (BCB) on proliferation of HUVEC. RESULTS: APS did not promote proliferation of HUVEC at 9.75 mg/L-2.5 g/L; Rh1 promoted proliferation of HUVEC at 1.94 mg/L-0.5 g/L (P<0.05 or P<0.01), and Rg1 inhibited proliferation of HUVEC at 31 mg/L (P<0.05); VAP promoted proliferation of HUVEC at 1 mg/L-0.5 g/L with optimal dose of 10 mg/L (P<0.01), Cinnamyl aldehyde promoted proliferation of HUVEC at 2 g/L(P<0. 05); Muscone and soluble extract of BCB inhibited proliferation of HUVEC at 1 g/L, 0.5-2.5 kg/L(P<0. 01), respectively; Perlolyrine inhibited proliferation of HUVEC at 0.125 g/L-0.5 g/L(P<0. 01). CONCLUSION: The external herbs for supplementing Qi and warming Yang can promote HUVEC proliferation and improve angiogenesis during tissue repair. The external herbs for promoting blood circulation and accelerating capillary movement may have influence upon other stages of tissue repair.
