Abstract: Objective To observe the effect of vinpecetine on inflammatory factors and lung pathology of the rats with chronic obstructive pulmonary disease(COPD),and to investigate the therapeutic action of vinpecetine on COPD.Methods Totally 40 Wistar rats were randomly divided into the normal control group,the COPD model group and three viupocetine treated groups.The COPD rat model wag established by intratracheal instillation of lipepalysaceharide and exposure to cigarette smoke.The three intervention groups were intrapedtonealy injected with vinpecetine respectively at the dose of 1.25 mg/kg,2.5 mg/kg and 5 mg/kg before exposing to cigarette smoke.Pathologic changes of the lung tissue,interlukin(IL)-8 and tumor necrosis factor (TNF)-a levels in bronchial alveolarhvage fluid(BALF)and seruln,and CRP level in the serum were determined.Results The pathological changes in the COPD rat model were coincident with the changes in human.Compared with the COPD model group,the two groups treated with vinpecetine at the dose of 2.5 mg/kg and 5 mg/kg showed a significan t decrease in IL-8[(18.40 ±2.40)ng/L,(19.30±3.11)ng/L respectively vs(23.81±3.54)ng/L],TNF-a[(39.34±3.43)ng/L,(40.47±3.09)ns/L respectivelyvs (46.65±4.42)ng/L],and CRP[(4.28±0.22)mg/L,(4.35±0.26)mg/L respectively vs(4.69±0.19)mg/L]in serum.In the BALF of those the BALF of those two groups, the levers of Ⅱ-8[(20.09 4±2.88)ng/L,(21.03±2.21)ng/L]and TNF-a[(40.41±4.40)ng/L,(41.18 4±5.33)ng/L]were also significantly lower than those in the moder group[(25.02±2.92).g/L,(48.81±4.92)ng/L].The vinpocetine treated group at the dose of 1.25mg/kg ad no significant difference, compared with the COPD model group. Conclusions Vinpocetine can reduce the levels of inflammatory factors in BALF and the serum of the rats with COPD and decrease inflammation of the airway and lung tissue. Accordingly vinpecetine can inhibit the inflammation of the COPD rat model.
