ABSTRACT
Objective To explore the relationship of vascular endothelial growth factor(VEGF),IFN-? and IL-4 and effect of Bude-sonide on their in asthmatic rats.Methods Thirty-six male SD rats were randomly divided into 3 groupsasthma group,Budesonide-treatment group and control group.On the first day of the experiment and the 8th day,the rat models of the asthma group and Budesonid treatment group were allergized by the OVA/Al(OH)3 through intraperitoneal injection,respectively.And starting from the 15th day,they were challenged by the OVA through atomization for 2 weeks.Control group was allergized and challenged by NS atomization.Budesonid treatment group was interfered in Budesonide inhalation before suscitation in 0.5 h.After 12 h the same inhal done was again in Budesonide group.Twenty-four hours after the last challenge,the rats in 3 groups were sacrificed,and blood and bronchoalveolar lavage fluid(BALF) were collected.The concentrations of IL-4,IFN-? and VEGF in serum and BALF were measured by enzyme-linked immunosorbent assay.Results The concentrations of IL-4 in serum and BALF in asthma group and Budesonide treatment group were significantly increased than those in control group(P
