| 摘要： | 目的：观察藏药麻花秦艽不同部位醇提物的抗炎作用。方法：72只雄性SPF级昆明种小鼠随机分为模型组[等体积0.5％羧甲基纤维素钠（CMC-Na）溶液]、醋酸泼尼松组（10 mg/kg）及麻花秦艽地上部位醇提物低、高剂量组（10、30 g/kg）与麻花秦艽地下部位醇提物低、高剂量组（10、30 g/kg），每组12只；灌胃给药，每天2次，连续6次；末次给药40 min后于小鼠右耳廓正反两面均匀涂抹二甲苯（0.05 mL）以建立耳肿胀模型，考察各组小鼠的耳肿胀度，并计算耳肿胀抑制率。分组同上；灌胃给药，每天2次，连续5次；末次给药40 min后于小鼠右足皮下注射1％角叉菜胶0.9％氯化钠溶液（0.05 mL）以建立足肿胀模型，考察各组小鼠的足肿胀度，并计算足肿胀抑制率。无菌条件下将灭菌棉球植于小鼠鼠蹊部皮下以建立肉芽肿模型；分组同上，建模24 h后灌胃给药，每天1次，连续10次；末次给药24 h后剥离棉球，考察各组小鼠的肉芽肿胀度，并计算肉芽肿胀抑制率。84只雄性SD大鼠随机分为正常对照组（等体积0.5％ CMC-Na溶液）、模型组（等体积0.5％ CMC-Na溶液）、醋酸泼尼松组（7 mg/kg）及麻花秦艽地上部位醇提物低、高剂量组（7、21 g/kg）与麻花秦艽地下部位醇提物低、高剂量组（7、21 g/kg），每组12只；灌胃给药，每天1次，连续30次；灌胃给药4次后于大鼠右后足皮下注射完全弗氏佐剂（0.1 mL）以建立关节炎模型；建模18 h后，考察各组大鼠的足肿胀度，并计算足肿胀抑制率，建模20 d后进行大鼠全身关节病变评分，末次给药24 h后称定大鼠胸腺、脾、肾上腺质量和体质量并计算相应脏器指数。结果：与模型组比较，醋酸泼尼松组、麻花秦艽地上部位醇提物高剂量组和麻花秦艽地下部位醇提物低、高剂量组小鼠耳肿胀度均显著降低（P＜0.05或P＜0.01），耳肿胀抑制率分别为67.12％、27.39％、19.86％、54.79％；麻花秦艽地下部位醇提物低、高剂量组小鼠足肿胀度均显著降低（P＜0.01），足肿胀抑制率分别为34.63％、46.07％；醋酸泼尼松组、麻花秦艽地上、地下部位醇提物低、高剂量组小鼠肉芽肿胀度均显著降低（P＜0.05或P＜0.01），肉芽肿胀抑制率分别为42.52％、14.02％、23.36％、21.50％、35.58％；醋酸泼尼松组和麻花秦艽地上、地下部位醇提物高剂量组大鼠关节肿胀度均显著降低，全身关节病变评分均显著降低（P＜0.05或P＜0.01）。与正常对照组比较，模型组大鼠胸腺、脾脏、肾上腺指数均显著降低（P＜0.01）；与模型组比较，麻花素艽地上、地下部位醇提物低、高剂量组各脏器指数差异均无统计学意义（P＞0.05）。结论：麻花秦艽地上、地下部位醇提物均具有一定的抗炎作用。 |
| ABSTRACT： | OBJECTIVE： To observe the anti-inflammatory activity of ethanol extract from different parts of Tibetan medicine Gentiana straminea. METHODS： Totally 72 male SPF Kunming mice were randomly divided into model group （constant volume of 0.5％ CMC-Na solution）；prednisone acetate group （10 mg/kg）， low-dose and high-dose groups of ethanol extract from aerial part of G. straminea （10， 30 g/kg）， low-dose and high-dose groups of ethanol extract from underground part of G. straminea （10， 30 g/kg）， with 12 mice in each group. They were given relevant medicine intragastrically twice a day for consecutive 6 times. Fourty minites after last medication， ear-swelling model was induced by evenly smeared with xylene （0.05 mL） on both sides of the right auricle. Fourty minites after modeling， the ear swelling degree and inhibitory rate of ear swelling of mice in each group were calculated. Grouping was the same as above， and then they were given relevant medicine intragastrically twice a day for consecutive 5 times. Fourty minites after last medication， mice were given 1％ carrageenan 0.9％ sodium chloride solution 0.05 mL subcutaneously via right feet to establish feet swelling model； the feet swelling degree and inhibitory rate of feet swelling of mice in each group were calculated. Sterile cotton balls were planted in groin area of mice under the aseptic condition subcutaneously to establish granuloma model. Twenty hours after modeling， grouping was the same as above， and then they were given relevant medicine intragastrically once a day for consecutive 10 times. Twenty hours after last medication， the cotton balls were removed； the granulation swelling degree and inhibitory rate of feet swelling of mice in each group were calculated. Eighty-four male SD rats were randomly divided into normal contrd group （constant volume of 0.5％ CMC-Na solution）， model group （constant volume of 0.5％ CMC-Na solution）， prednisone acetate group （7 mg/kg）， aerial part ethanol extract of G. straminea low-dose and high-dose groups （7， 21 g/kg）， ethanol extract of G. straminea underground part low-dose and high-dose groups （7， 21 g/kg）， with 12 rats in each group. They were given relevant medicine intragastrically once a day for consecutive 30 times. After 4 times of intragastric administration， rats were injected with complete Freund’s adjuvant （0.1 mL） into the right hind foot to establish arthritis model. Eighteen hours after modeling， the feet swelling degree and inhibitory rate of feet swelling of rats in each group were calculated； 20 d after modeling， systemic lesion scores of rats in each group were conducted； 24 h after last medication， the weight of thymus， spleen， adrenal gland and body weight were weighed and relevant viscera indexes were calculated. RESULTS： Compared with model group， the auricle swelling degree of mice were decreased significantly in prednisone acetate group， high-dose group of ethanol extract from aerial part of G. straminea， low-dose and high-dose groups of ethanol extract from underground part of G. straminea （P＜0.05 or P＜0.01）； inhibitory rates of ear swelling were 67.12％， 27.39％， 19.86％， 54.79％， respectively. Feet swelling degree were decreased significantly in low-dose and high-dose group of ethanol extract from underground part of G. straminea （P＜0.01）； inhibitory rates of feet swelling were 34.63％ and 46.07％. The granulation swelling degree were decreased significantly in prednisone acetate group， low-dose and high-dose groups of ethanol extract from aerial part of G. straminea， low-dose and high-dose groups of ethanol extract from underground part of G. straminea （P＜0.05 or P＜0.01）； inhibitory rates of granulation swelling were 42.52％， 14.02％， 23.36％， 21.50％， 35.58％， respectively. The joint swelling degree of rats were decreased significantly in prednisone acetate group， low-dose and high-dose groups of ethanol extract from aerial part of G. straminea， low-dose and high-dose groups of ethanol extract from underground part of G. straminea （P＜0.05 or P＜0.01）； while systemic lesion score were decreased significantly （P＜0.05 or P＜0.01）. Compared with normal control group， thymus， spleen， adrenal indexes of rats were increased significantly in model group （P＜0.01）； compared with model group， viscera indexes of rats were not statistical different in low-dose and high-dose groups of ethanol extract from aerial part of G. straminea， low-dose and high-dose groups of ethanol extract from underground part of G. straminea （P＞0.05）. CONCLUSIONS： The ethanol extract from aerial part and underground part of G. straminea both have anti-inflammatory effects. |
