Objective This study construct a pulmonary fibrosis model in vivo to study anti-pulmonary fibrosis effect of ampelopsis.Methods We constructed a pulmonary fibrosis model by bleomycin in BALB/c mice. The mice were divided by weight random number table into a blank control group, a model control group, a dexamethasone treatment group (intervened with dexamethasone in a dose of 2.5 mg/kg), and three ampelopsis treatment groups intervened with ampelopsis in dose of 200, 100, and 50 mg/kg, respectively. Bleomycin solution (3 mg/kg) was intratracheally injected respectively on 1st and 14th day, except the blank group. Twenty-eight days later, the relevant indicators were collected, including respiratory function (airway resistance, dynamic lung compliance, maximal ventilator volume), level of hydroxyproline and histopathological changes in the lungs.Results After 28 days, the model control group mice had severe respiratory resistance, dynamic lung compliance and maximal ventilator volume were decreased. The high dose ampelopsis treatment could enhance respiratory function (P<0.05). Lung coefficient was lower in the treatment groups than that in the model control group (P<0.05). The hydroxyproline of the treatment groups was less than that of the model control group (P<0.05). Histopathological examination showed that the degree of fibrosis increased in the model control group (P<0.05), but decreased in the treatment groups (P<0.05).Conclusion Ampelopsis can resist bleomycin-induced pulmonary fibrosis in mice, relieve the symptoms of respiratory failure, reduce the formation of collagen, and produce anti-pulmonary fibrosis effect.
