【摘要】 目的:研究高山辣根菜水提物的止咳与抗炎作用。方法:实验分为模型组、阳性对照[可待因30(小鼠)、18.38(豚鼠)mg/kg;吲哚美辛20(小鼠)、15(大鼠)mg/kg]组、高山辣根菜低、中、高剂量[小鼠予以2.0、4.0、8.0 g(生药)/kg;豚鼠予以1.2、2.4、4.8g(生药)/kg;大鼠予以1.4、2.8、5.6 g(生药)/kg]组,每组10只,连续ig给药4 d。分别采用浓氨水喷雾法和二氧化硫刺激法致咳考察小鼠的咳嗽潜伏期和咳嗽次数,枸橼酸喷雾法致咳考察豚鼠的咳嗽潜伏期和咳嗽次数,耳肿胀法考察二甲苯诱发的小鼠耳片肿胀度,足爪肿胀法考察角叉菜胶诱发的大鼠足爪肿胀度。结果:与模型组比较,阳性对照组和高山辣根菜中、高剂量组小鼠浓氨水喷雾和二氧化硫刺激诱发咳嗽潜伏期延长、咳嗽次数减少,高山辣根菜中、高剂量组豚鼠咳嗽潜伏期延长、咳嗽次数减少;高山辣根菜中、高剂量组小鼠由二甲苯诱发的耳片肿胀度减小;高山辣根菜中、高剂量组大鼠由角叉菜胶诱发的足爪肿胀度减小;以上差异均具有统计学意义(P<0.01或P<0.05)。结论:高山辣根菜水提物对实验动物具有止咳、抗炎作用。更多还原

【Abstract】 OBJECTIVE:To study the anti-tussive and anti-inflammatory effects of aqueous extract of Pegaeophyti Radix Et Rhizoma(P. Radix Et Rhizoma). METHODS:In the experiment,there were a model group,a positive control group [30 mg/kg codeine for mice,18.38 mg/kg codeine for guinea pigs,20 mg/kg indometacin for mice and 15 mg/kg indometacin for rats] and P. Radix Et Rhizoma low-dose,medium-dose and high-dose groups [2.0,4.0 and 8.0 g(medicinal materials)/kg for mice;1.2,2.4 and4.8 g(medicinal materials)/kg for guinea pigs;1.4,2.8 and 5.6 g(medicinal materials)/kg for rats],with 10 animals in each group. The above-mentioned animals were given corresponding drug ig for 4 consecutive days,and then strong ammonia spraying method and sulfur dioxide stimulation method were employed to induce cough in mice and citric acid spraying method to induce cough in guinea pigs to observe the incubation period and times of cough,auricular swelling method to observe xylene-induced auricular swelling in mice and pedal swelling method to observe carrageenin-induced pedal swelling in rats. RESULTS:Compared to the model group,Aqueous extract of P. Radix Et Rhizoma could prolong the incubation period and reduce times of cough induced by strong ammonia spraying and sulfur dioxide stimulation in mice of positive control group and P. Radix Et Rhizoma medium-dose and high-dose groups;it could prolong the incubation period of and reduce times of cough induced by citric acid spraying in guinea pigs of positive control group and P. Radix Et Rhizoma medium-dose and high-dose groups;it could alleviate xylene-induced auricular swelling in mice of positive control group and P. Radix Et Rhizoma medium-dose and high-dose groups;it could alleviate carrageenin-induced pedal swelling in rats of positive control group and P. Radix Et Rhizoma medium-dose and high-dose groups. There were statistically significances(P<0.01 or P<0.05). CONCLUSIONS:Aqueous extract of P. Radix Et Rhizoma has anti-tussive and anti-inflammatory effects on the experimental animals.更多还原
