The analgesic effect was determined with the models of acetic acid writhing. 醋酸扭体法致腹痛模型,观察"盆炎洁颗粒"镇痛作用。
Zuotongning injection can obviously inhibit the writhing action induced by acetic acid and enhance the analgesic effect induced by the hot-plate test in mice. 坐痛宁注射液能明显抑制醋酸所致的小鼠扭体反应，能提高小鼠对热板试验所致的镇痛效应。
Results: 1) PPL could dose-dependently raise the pain threshold in tail stimulation-vocalization test in rats and inhibit the writhing reaction induced by acetic acid in mice. 方法：采用扭体法、电刺激鼠尾-嘶叫法、钾离子透入法和辐射热-缩腿法等行为学指标以及丘脑束旁核神经元对伤害性刺激的放电反应的电生理指标。
The number of writhing within 15min in the AMG+L-Arg group was strikingly more than that in the AMG group in the acetic acid test of mice, while the number in the AMG +L-NAME group was notably fewer than that in the AMG group (F<0.05) in the same test. 与AMG组比较AMG+LNAME组FA致痛第二时相小鼠累计舔足时间显著减少，而AMG+LArg组FA致痛第二时相小鼠累计舔足时间显著延长(尸<0 .
Methods: The method of writhing by acetic acid, hot-plate and electric stimulation in mice were made to study the analgesic effect of HE extract. 方法:采用醋酸扭体法、热板致痛法、电刺激致痛法观察淫羊藿水提取液对小鼠的镇痛作用。
