【摘要】 作者在19只家兔足背部及其周围皮肤涂抹湿润烧伤膏（MEBO），用行为测痛方法测定涂抹MEBO前后的痛阈的变化。结果发现，在涂抹MEBO后一定时间内，痛阈明显升高，经统计学处理P＜0.001或0.01，而涂抹凡士林后，痛阈无明显变化P＞0.05。由此说明MEBO参与了皮肤的镇痛作用。更多还原

【Abstract】 MEBO was applied to the skin of the foot back arid its surrouridirig area of 19 rabbits and the pain threshold was determined with behavioral method,before arid after the application of MEBO. The result showed that the pain threshold of the rabbilts was markedly raisedduring a time length after the application of MEBO,which was statistically significant (P＜0.001or 0.01 ),while no such change occurred after application of vaseline (P＞0.005 ). The result indicated MEBO could play an analgesic role in the skin of rabbits.更多还原
