摘要
目的探讨海藻玉壶汤中加减运用反药组合对甲状腺肿大模型大鼠疗效的影响。方法将大鼠随机分为空白组、模型组、阳性药(优甲乐)组、海藻玉壶汤全方组、海藻玉壶汤去反药组3组(分别为海藻玉壶汤减甘草组、海藻玉壶汤减海藻组、海藻玉壶汤减海藻甘草组),除空白组外,其余各组灌服丙硫氧嘧啶复制甲状腺肿大模型,以优甲乐作为阳性对照药,各给药组分别给予相应药物。检测各组大鼠甲状腺系数,甲状腺激素水平,甲状腺激素的合成、转运、调控等相关指标;光镜下观察大鼠甲状腺组织形态改变,并统计切片细胞核数、滤泡面积。结果海藻玉壶汤同阳性药一致,表现出对甲状腺肿大模型大鼠甲状腺激素水平的回调作用,且较好地恢复了模型大鼠甲状腺的形态。全方组与各拆方组比较甲状腺激素相关指标水平,其恢复情况为海藻玉壶汤组>海藻玉壶汤减甘草组>海藻玉壶汤减海藻组>海藻玉壶汤减海藻甘草组;与各拆方组比较甲状腺组织病理形态,其改善情况为海藻玉壶汤组>海藻玉壶汤减海藻甘草组>海藻玉壶汤减海藻组>海藻玉壶汤减甘草组。结论海藻玉壶汤全方组对甲状腺肿大大鼠甲状腺激素水平以及病理形态的改善要优于去掉反药的各拆方组,拆方组中海藻玉壶汤减海藻甘草组疗效最差。
Objective To comparative the thyroid hormone level and histopathological changes of the thyroid tissue in PTU-induced goiter rats treated with Haizao Yuhu Decoction and its recipe minus antagonistic medicinal combination,and to explore whether eliminating antagonistic medicinal combination in Haizao Yuhu Decoction can affect the therapeutic effect.Methods The rats were randomly divided into the blank group,model group,positive drug group(euthyrox),Haizao Yuhu Decoction group,Haizao Yuhu Decoction minus Glycyrrhizae group,Haizao Yuhu Decoction minus Sargassum group,and Haizao Yuhu Decoction minus Sargassum and Glycyrrhizae group.The rat model of goiter was induced with propylthiouracil.Each group was fed with the corresponding drug or decoction.The concentration of serum related indicators was detected,including the thyroid coefficient,thyroid hormone level and its synthesis,transport and regulation.Under light microscope,pathological changes of thyroid tissue in rats were observed,and nucleic number and follicular area in sections were counted.Results Like the positive drug,Haizao Yuhu Decoction was consistent with the positive drug of euthyrox in maintaining thyroid functions and recovering the pathological damage of thyroid tissue in PTU-induced goiter rats.Comparing the thyroid hormone related indicators,the degree of recovery was listed:Haizao Yuhu Decoction group>Haizao Yuhu Decoction minus Glycyrrhizae group>Haizao Yuhu Decoction minus Sargassum group>Haizao Yuhu Decoction minus Sargassum and Glycyrrhizae group.Comparing the histopathological changes of the thyroid tissues,the alleviating degree was listed:Haizao Yuhu Decoction group>Haizao Yuhu Decoction minus Sargassum and Glycyrrhizae group>Haizao Yuhu Decoction minus Sargassum group>Haizao Yuhu Decoction minus Glycyrrhizae group.Conclusion The therapeutic effect of Haizao Yuhu Decoction in regulating thyroid hormone level and improving histopathological changes in goiter rats seems to be better than its recipe minus antagonistic medicinal combination,and the Haizao Yuhu Decoction minus Sargassum and Glycyrrhizae tends to have the least effect.
