摘 要:目的:观察软坚消瘿汤对实验性自身免疫性甲状腺炎(EAT)大鼠的自身抗体、白介素-1、4、6及肿瘤坏死因子-α和甲状腺形态学的影响,从多靶点探讨其作用机制。方法:运用甲状腺球蛋白与弗氏佐剂混合免疫注射法,联合饮用高碘水模拟大鼠实验性自身免疫性甲状腺炎。酶联免疫法检测甲状腺抗体、白介素-1、4、6及肿瘤坏死因子-α水平,HE染色法观察大鼠甲状腺病理改变。结果:软坚消瘿汤能显著降低EAT大鼠自身抗体及相关细胞因子水平,减轻甲状腺滤泡损伤。结论:软坚消瘿汤通过降低EAT血清中自身抗体及细胞因子水平起到减轻甲状腺病理损伤的作用。

Abstract:Objective:To evaluate the therapeutic effect of Xiaoying Ruanjian Decoction on experimental autoimmune thyroiditis (EAT) from the levels of autoantibodies, interleukin-1,4,6 and tumor necrosis factor-α and the thyroid morphology of EAT rats.To Investigate the effect Mechanism from multiple target point.Methods:An animal model of experimental autoimmune thyroiditis ( EAT) in rats was developed by injecting thyroglobulin mixed with Freund's adjuvant immunization and drinking Periodate water. To detect the levels of autoantibodies, interleukin-1,4,6 and tumor necrosis factor-α with Enzyme-linked immunosorbent assay.To observe the pathological change in the thyroid of rat with HE staining.Results:Ruanjian Xiaoying Decoction significantly reduces the levels of autoantibody, cytokines and the damage of thyroid follicular.Conclusion:Ruanjian Xiaoying Decoction alleviates the pathological injury of thyroid by the suppression of relative expressions of antibodies and cytokines in serum levels.
Key words:Ruanjian Xiaoying Decoction; experimental autoimmune thyroiditis; serum antibody; cytokine; TCM Experimental Medicine
自身免疫性甲状腺炎是常见甲状腺病之一,目前尚缺乏有效治疗措施。软坚消瘿汤是笔者运用中医药理论,总结前辈及自己多年治疗经验创立的治疗本病的中药复方。此方具疏肝行气解郁、活血软坚散结之功,前期临床疗效甚好。早期动物实验研究揭示了其治疗EAT的部分机理,本实验旨在从本方对细胞因子及抗体的影响来探讨其疗效机制。
