白花丹止痛喷雾剂的抗炎镇痛作用研究

【目的】研究白花丹止痛喷雾剂的抗炎、镇痛作用,为进一步开发新药提供理论依据。【方法】通过二甲苯致小鼠耳炎症、蛋清致大鼠足肿胀实验及测定炎症组织中前列腺素(PGE_2)含量观察白花丹止痛喷雾剂的抗炎效应;采用小鼠热板法、醋酸扭体法观察白花丹止痛喷雾剂的镇痛作用。【结果】中剂量白花丹止痛喷雾剂(1 mg/mL)明显降低二甲苯所致小鼠耳廓肿胀率,可显著提高小鼠的热板痛阈值,延长小鼠的疼痛潜伏期(P0.05或P0.01);高剂量白花丹止痛喷雾剂(2 mg/mL)能减少大鼠足炎症组织中PGE_2的含量(P0.05),且在减少小鼠扭体反应次数方面的作用显著优于扶他林组。【结论】白花丹止痛喷雾剂具有较强的抗炎、镇痛作用。

Studies on Anti-inflammatory and Analgesic Effects of Baihuadan Analgesic Spray

Objective To study the anti-inflammatory and analgesic effects of Baihuadan Analgesic Spray, so as to provide theoretical basis for further development of new drugs. Methods Prostaglandin E2 (PGE2) in the inflammatory tissues of mice with xylene-induced auricular inflammation and in the rats with albumen-induced pedal swelling were measured for the observation of anti-inflammation action of Baihuadan Analgesic Spray. The pain threshold in mouse hot-plate test and mouse acetic acid writhing test was determined to observe the analgesic effect of Baihuadan Analgesic Spray. Results Middle dose of Baihuadan Analgesic Spray (1 mg/mL) significantly reduced the auricular swelling rate induced by xylene in mice, improved the pain threshold of mice and prolonged pain latency in hot plate test (P < 0.05 or P < 0.01). High dose of Baihuadan Analgesic Spray (2 mg/mL) reduced the content of PGE2 in pedal inflammatory tissues (P < 0.05), and the effect on reducing the times of mouse writhing was obviously superior to that of the Voltaren Gel group. Conclusion Baihuadan Analgesic Spray has obvious anti-inflammatory and analgesic effects.
