Objective:To observe the depressant effect of the Compound Qingre Granule-Serum(SQ)on extended-spectrum beta-lactamase(ESBLs).Methods:According to ultraviolet spectrophotometry
different concentration SQ's β-lactamase inhibiting effect was determined.The effect was tested by changes of optical density in ultraviolet light induced by ampicillin.Results:33.3% SQ can inhibit the β-lactamase effect of ATCC700603 more than 50%
and had significant difference to control group.The β-lactamase inhibiting effect of SQ also showed positive correlation with its concentration.Conclusion:SQ can inhibit the action of ESBLs significantly.It may be one of the mechanisms of the granule for curing drug-resistance bacteria infections.
