虎杖通络搽剂消肿镇痛作用的药理学研究

Pharmaceutical Study on Anti-Swelling and Alleviating Pain Action of Huzhangtongluo Liniment

目的进行虎杖通络搽剂消肿镇痛的药理学研究。方法对二甲苯所致小鼠耳肿胀的影响:各组动物给药3次/d,连续3d,动物处死后,用直径8mm的打孔器于小鼠两耳相同部位打下耳片,分别称重,以左右耳片重量之差作为肿胀度;对甲醛所致小鼠足肿胀的影响:各组给药动物致炎4h,颈椎脱臼处死,在小鼠后足同一部位剪下左右后足称重,以左右后足重量差为肿胀度;对大鼠皮下埋棉球所致肉芽组织增生的影响:各组给药动物6h处死,手术剥离肉芽组织,于70℃烘箱内烘干,称量,计算肉芽组织干重并进行统计学处理;对小鼠热刺激痛阈的影响:给药各组动物,测定30、60、90min小鼠的痛阈值,如舔足、跳跃、抬足,若60s仍无反应者应立即将小鼠取出,并按60s计算痛阀值。结果虎杖通络搽剂可明显抑制二甲苯所致小鼠耳肿胀和甲醛所致小鼠足肿胀,对大鼠皮下埋植棉球所致肉芽组织增生亦有明显抑制作用,热板镇痛实验表明其能明显提高小鼠痛阀值。结论虎杖通络搽剂具有消肿镇痛作用。

Objectve To study the effect of anti-swelling and alleviating pain of Huzhangtongluo liniment. Method Mice with xylol-induced auricular swelling： the mice of each group were administered three times per day for 3 days. The inflammed mice were killed and punched a patch on left and right ear in 8 mm diameter, the weight margin of two patch was the rate of swelling. Mice with formalin-induced podalic swelling： the inflammed mice of each group were administered after 4 hours, by dislocating their cervical vetebra. The mice posterior feet were cut at the same place and weighed, the weight margin of left and right foot was the rate of swelling. Rat with granulation induced by cotton embedded under dermis： the rat of each group were administered and then killed after 6 hours, the granulation tissue of rat was separated, dried in oven at temperature of 70℃ and weighed, the data of dry weight was calculated and processed by statistics. The pain threshold of mice stimulated by heat, the pain threshold of administered mice was determined at 30, 60, 90 min. The threshold value was calculated as 60 s if the mice had no action such as licking foot, jumping or lifting foot after 60 s. Result Huzhangtongluo liniment can obviously inhibit auricular swelling induced by xylol and podalic swelling induced by formalin as well as granulation induced by cotton embeded under dermis. The preparations can clearly enhance pain-threshold value of mice in hot-plate method. Conclusion Huzhangtongluo liniment has the action of anti-swelling and alleviating pain.
