慢性重型肝炎患者肠道定植抗力变化的研究

目的应用微生态学方法了解慢性重型肝炎患者肠道定植抗力的变化.方法应用光冈法对肠道目的菌群(双歧杆菌、肠杆菌、肠球菌、酵母菌)进行定性定量研究,并计算双歧杆菌与肠杆菌比值(B/E值).结果与正常组比较,慢性重型肝炎患者的肠道肠杆菌(8.05±0.96对9.00±0.63,P＜0.001)、肠球菌(7.19±1.04对8.62±1.07,P＜0.001)、酵母菌(3.32±0.97对4.96±1.81,P＜0.01)的数量显著增加,而双歧杆菌数量(9.62±0.88对7 45±2.00,P＜0.001)及B/E值(1.23±0.18对0.83±0.23,P＜0.001)显著下降.结论慢性重型肝炎患者的肠道定植抗力下降,受损严重.

Study on the intestinal microbial colonization resistance in patients with chronic severe hepatitis

OBJECTIVE: To investigate the changes of microbial colonization resistance of the bowel in patients with chronic severe hepatitis. METHODS: The fecal flora bifidobacteria, enterobacteriaceae, enterococci, and yeasts of subjects (chronic severe hepatitis, chronic hepatitis, and healthy volunteers) were quantitatively and qualitatively analyzed by Mitsuoka's methods. While the ratio of bifidobacterium to enterobacteriaceae ( B/E ratio ) was calculated. RESULTS: The number of bifidobacteria and the B/E ratio in chronic severe hepatitis group was significantly deceased compared with that of the control group (P<0.001). The number of enterobacteriaceae and yeasts was significantly increased compared with that of control group (P<0.001 and P<0.01, respectively). CONCLUSIONS: The results suggest that the intestinal microbial colonization resistance in patients with chronic severe hepatitis is seriously impaired.
