目的:探索不同中药提取物对幽门螺杆菌( helicobter pylori, H.pylori)耐药菌株是否具有体外抗菌活性,为中药治疗H.pylori耐药菌株提供依据。方法采用琼脂稀释法分别检测不同中药乙醇提取物对H.pylori标准菌株和临床耐药菌株的最小抑菌浓度( MIC ),分别计算其MIC50和MIC90。结果中药提取物大黄、黄连、黄芩、败酱草、延胡索的MIC50和MIC90分别为:32,64,32,64,128,256,>512,>512,>512,>512 mg/L。结论大黄及黄连提取物对H.pylori临床耐药菌株具有较明显的体外抑菌作用;黄芩提取物对H.pylori临床耐药菌株具较弱的体外抑菌作用;败酱草、延胡索提取物对于H.pylori临床耐药菌株无明显体外抑菌作用。
目的:探索不同中藥提取物對幽門螺桿菌( helicobter pylori, H.pylori)耐藥菌株是否具有體外抗菌活性,為中藥治療H.pylori耐藥菌株提供依據。方法採用瓊脂稀釋法分彆檢測不同中藥乙醇提取物對H.pylori標準菌株和臨床耐藥菌株的最小抑菌濃度( MIC ),分彆計算其MIC50和MIC90。結果中藥提取物大黃、黃連、黃芩、敗醬草、延鬍索的MIC50和MIC90分彆為:32,64,32,64,128,256,>512,>512,>512,>512 mg/L。結論大黃及黃連提取物對H.pylori臨床耐藥菌株具有較明顯的體外抑菌作用;黃芩提取物對H.pylori臨床耐藥菌株具較弱的體外抑菌作用;敗醬草、延鬍索提取物對于H.pylori臨床耐藥菌株無明顯體外抑菌作用。

Objective To find antibacterial activity of traditional Chinese herbal medicine extracts on antibiotic-resistant Helicobacter pylori ( H.pylori) stralns in vitro, which could provide the evidence for treating antibiotic-resistant H.pylori stralns with Chinese herbal medicines.Methods Agar dilution was used to detect the minimum inhibitory concentration ( MIC) of standard straln and clinical drug resistant straln different of traditional Chinese herbal medicine extracts, and MIC50 and MIC90 were calculated. Results The MIC50 and MIC90 of traditional Chinese medicine extracts on H.pylori clinical isolates were as follows respectively:rhubarb:32 mg/L and 64 mg/L, Rhizoma Coptidis:32 mg/L and 64 mg/L, radix scutellariae:128 mg/L and 256 mg/L, herba patriniae >512 mg/L and >512 mg/L, rhizoma corydalis >512 mg/L and >512 mg/L.Conclusions The results of this study suggest that the extracts of rhubarb and rhizoma coptidis have obvious antibacterial activity, while radix scutellariae has weak antibacterial activity, on H.pylori clinical antibiotic resistant isolates in vitro, herba patriniae and rhizoma corydalis have no significant antibacterial activity.
