摘要: 研究冠盖藤水提物对膝骨性关节炎大鼠血液及关节液COX2、NO、iONS含量的影响。将SD大鼠分为正常对照组、模型组、阳性组(硫酸氨基葡萄糖组)、冠盖藤中、高剂量组,制备4%木瓜蛋白酶溶液与0.3 mol/L半胱氨酸溶液(1:1)的混合液,分别于第1、3、7 d注入SD大鼠右膝关节造模,每次20 μL。冠盖藤中、高剂量组以4.62 g生药/kg、9.24 g生药/kg,阳性组以0.133 mg/kg硫酸氨基葡萄糖分别灌胃,正常对照组和模型组分别予以等量蒸馏水;连续给药4周后,进行指标测定。与模型组比较,冠盖藤中、高剂量组血液及关节液中COX2、iONS、NO含量明显降低,能有效抑制关节软骨组织形态的改变,间接保护软骨细胞和促进受损软骨细胞恢复的作用。冠盖藤能有效抑制关节液中COX2、NO、iONS表达,保护软骨细胞和促进受损软骨细胞恢复的作用,是延缓关节软骨退变的机制之一。

Abstract: In this study,the effect of Pileostegia viburnoides water extract on the contents of COX2, NO, iONS in blood and joint fluid of rats with knee osteoarthritis was studied. The SD rats were randomly divided into 5 groups:normal control group,model group,GS-positive group (glucosamine sulfate group), P.Viburnoides middle dose group and P.viburnoides high dose group.The rat model with knee osteoarthritis was built by injecting a mixture of 4% papain solution and 0.3 mol/L cysteine solution (1:1) into the right knee joint of SD rat at the first,3rd and 7th days,20 μL at a time.The P.viburnoides middle,high dose groups were intragastrically administrated with 4.62 g/kg and 9.24 g/kg of P.viburnoides water extract.The GS-positive group was intragastrically administrated with 0.133 mg/kg of glucosamine sulfate.The normal control and model groups were intragastricaly administrated with the same volume of distilled water.After 4 weeks treatment,the contents of COX2,NO,iONS in the blood and joint fluid in P.viburnoides middle and high dose groups were decreased significantly compared with that of model group.In addition,the results showed that P.viburnoides can effectively inhibit the histomorphologic changes of articular cartilage tissue,indirectly protect cartilage cells and stimulate the recovery of damaged cartilage cells. P.viburnoides can effectively inhibit the expression of COX2,NO,iONS in synovial fluid and it is one of the mechanisms of delaying the degeneration of articular cartilage.

Key words: Pileostegia viburnoides, osteoarthritis, COX2, NO, iONS, cartilage histomorphology
