摘要: 目的 研究紫虎烧伤膏的抑菌作用强度。方法 采用体外试验测定紫虎烧伤膏的MIC和MBC,纸片法比较紫虎烧伤膏和湿润烧伤膏对不同代表性菌种抑菌圈大小;动物实验比较紫虎烧伤膏和湿润烧伤膏用于大鼠Ⅱ度烫伤模型24 h,48 h后创面菌落计数。结果 紫虎烧伤膏对金黄色葡萄球菌的MIC(Minimum inhibitory concentration)为8 mg/mL,MBC (Minimum bactericidal concentration)32 mg/mL;对铜绿假单胞菌的MIC为16 mg/mL,MBC32 mg/mL;对大肠杆菌的MIC为16 mg/mL,MBC64 mg/mL。抑菌圈试验结果显示,紫虎烧伤膏和湿润烧伤膏没有显著性差异。动物实验表明,紫虎烧伤膏和湿润烧伤膏均有不同程度的抑制大鼠Ⅱ度烫伤局部细菌的作用。紫虎烧伤膏的作用更强。用药时间越长,抑菌效果越明显。结论 紫虎烧伤膏能够有效抑制Ⅱ度烧烫伤局部细菌,防止烧烫伤创面感染,保护创面,从而起到治疗Ⅱ度烫伤的作用。

Abstract: Objective To study the antibacterial effect of the purple tiger burn ointment. Methods The MIC and MBC were determined by using in vitro test. Comparison of the inhibition zone size of the different representative strains of the purple tiger burn ointment and the moist burn ointment were made, the animal experiment was used to compare the colony count of the wound of the rat model of second degree scald after 24 h, 48 h with the purple tiger burn ointment and the moist burn ointment. Results MIC(Minimum inhibitory concentration)of purple tiger burn ointment on Staphylococcus aureus was 8 mg/mL, MBC(Minimum bactericidal concentration ) of purple tiger burn ointment on Staphylococcus aureus was 32 mg/mL; MIC of purple tiger burn ointment on Pseudomonas aeruginosa was 16 mg/mL, MBC of purple tiger burn ointment on Pseudomonas aeruginosa was 32 mg/mL, MIC of purple tiger burn ointment on Escherichia coli was 16 mg/mL, MBC of purple tiger burn ointment on Escherichia coli was 64 mg/mL. The results showed that there was no significant difference between the purple tiger burn ointment and the moist burn ointment. Animal experiments showed that the purple tiger burn ointment and the moist burn ointment had different degrees of inhibition of the role of local bacteria in the second degree scald in rats. Purple tiger burn cream showed stronger function. The longer the time took, the more obvious the antibacterial effect was. Conclusion The purple tiger burn ointment can effectively inhibit the second degree burn of local bacteria, prevent the wound infection and protect the wound, so as to play a role in the treatment of second degree scald.
