摘要:
目的 对比研究龙血竭凝胶和麒麟竭凝胶的抗炎和抑菌作用,为血竭及其剂型的开发利用提供实验室依据。 方法 采用二甲苯致小鼠耳廓肿胀和棉球致小鼠肉芽肿模型检测比较两种血竭凝胶抗炎作用效果,通过肉汤培养基比色法比较两种血竭凝胶对金黄色葡萄球菌、表皮葡萄球菌、痤疮丙酸杆菌、白色念珠菌和大肠杆菌的抑菌作用效果。 结果 二甲苯致耳廓肿胀实验中,与空白对照组相比,糠酸莫米松凝胶和麒麟竭凝胶高剂量组对小鼠耳廓肿胀度有抑制作用(P < 0.05),其余各组差异没有统计学意义(P > 0.05);与糠酸莫米松凝胶组相比,空白对照组和麒麟竭凝胶高剂量组有显著性差异(P < 0.05),其余各组差异无统计学意义(P > 0.05),糠酸莫米松凝胶、龙血竭、麒麟竭凝胶高、中、低剂量组肿胀抑制率分别为34.44%、13.75%、4.44%、1.85% 36.67%、1.11%、0.08%。;棉球肉芽肿实验中,与空白对照组相比,糠酸莫米松凝胶组和龙血竭凝胶低剂量组(6 mg)对棉球致小鼠肉芽肿有抑制作用(P < 0.05),其余各组差异没有统计学意义(P > 0.05);与糠酸莫米松凝胶组相比,空白对照组和麒麟竭凝胶高剂量组有显著性差异(P < 0.05),其余各组差异无统计学意义(P > 0.05),糠酸莫米松凝胶、龙血竭、麒麟竭凝胶高、中、低组肿胀抑制率分别为28.26%、9.61%、4.44%、28.65%、36.67%、1.37%、13.40%。。两种血竭凝胶对金黄色葡萄球菌、表皮葡萄球菌、大肠杆菌、痤疮丙酸杆菌和白色念珠菌均有抑制作用,对金黄色葡萄球菌和表皮葡萄球菌麒麟竭凝胶最小抑菌浓度(MIC)为200 mg/mL,龙血竭凝胶最小抑菌浓度(MIC)为50 mg/mL;对痤疮丙酸杆菌麒麟竭凝胶和龙血竭凝胶MIC分别为100 mg/mL和50 mg/mL;对白色念珠菌麒麟竭凝胶和龙血竭凝胶MIC分别为100 mg/mL和200 mg/mL;对大肠杆菌麒麟竭凝胶和龙血竭凝胶MIC均为100 mg/mL。 结论 龙血竭凝胶和麒麟竭凝胶均具有抗炎抑菌的作用。龙血竭凝胶在抑制小鼠棉球肉芽肿和对抗金黄色葡萄球菌、表皮葡萄球菌、痤疮丙酸杆菌方面效果优于麒麟竭凝胶;麒麟竭凝胶在抑制二甲苯致小鼠耳廓肿胀和对抗白色念珠菌方面效果优于龙血竭凝胶,两种血竭凝胶对大肠杆菌的抑菌效果相同。 Abstract:Objective To comparatively study the anti-inhibitory and bacteriostatic effects of RDD and RDC gel so as to provide the laboratory basis for the development and utilization of the resin. Methods The model of the mouse pinna swelling induced by xylene and granuloma induced by cotton ball was adopted to test the anti-inflammatory effects of two kinds of the resin gel and the bacteriostatic effects of two kinds of the resin gel on Staphylococcus aureus, Staphylococcus epidermidis, Propionibacterium Acne, Candida albicans and Escherichia coli were compared by means of broth medium colorimetry. Results Compared with the blank control group in the test of auricle swelling induced by xylene, momethasone furoate gel(0.1 mg/) and high dose(12 mg/) of RDD gel inhibited the auricle swelling in mice(P < 0.05), but there were no statistical differences in the other two groups(P > 0.05); Compared with the momethasone furoate o gel group, the blank control group and the high dose RDD group had the significant difference(P < 0.05), but there were no statistical differences in the other two groups(P > 0.05). Compared with the blank control group in the experiment of granuloma model caused by cotton ball, the low dose RDC gel group had inhibitory effect on granulomal in mice, but there were no statistical differences in the other two groups(P > 0.05); Compared with the mometasone furoate group, the blank control group and the high dose RDD blood group had the significant differences(P < 0.05) but there were no statistical differences in the other groups(P > 0.05). The two kinds of resin gels had the inhibition to Staphylococcus aureus, Staphylococcus epidermidis, Propionibacterium Acne, Candida albicans and Escherichia coli. The minimal inhibitory concentration(MIC) of RDC gel was 50mg/mL and RDD gel was 200mg/mL for staphylococcus aureus and staphylococcus epidermidis; the MIC of propionibacterium acnes RDD gel and dragon resin gel were 100 mg/mL and 50 mg/mL, ; the MIC of Candida albicans RDD gel and RDC gel were 100 mg/mL and 200 mg/mL, respectively; the MIC of E. coli RDD gel and RDC gel were 100 mg/mL. Conclusion Both RDD gel and RDC gel have the anti-inflammatory and bacteriostatic effects. The RDC gel is superior to RDD gel in inhibiting granuloma of mouse cotton ball and fighting against Staphylococcus aureus, Staphylococcus epidermidis and Propionibacterium Acne; the effect of RDD gel on inhibiting auricle swelling induced by xylene in mice is better than that of RDC gel. There is the same bacteriostatic effect in the two kinds of resin gel on E. coli. -
