Abstract: OBJECTIVE:To study the effects of environmental factors on the degree of injury and expression of vascular endothelial growth factor(VEGF) and interleukin-1(IL-1) in cartilage cells of the joint in a rat model of adjuvant arthritis(AA).METHODS:SD rats aged 10 months were randomly divided into 4 groups that varied by temperature and humidity housing conditions and induction of AA:a control group,a model group,a cold-damp group,and a hot-damp group.All groups except the control group were induced with AA.After 4 w,VEGF and IL-1 expression in cartilage cells of ankle joints of hind limbs were observed.RESULTS:Mean area,optical density,and numbers of VEGF-and IL-1-positive cells in the model group,the cold-damp group,and the hot-damp group were significantly higher than that of the control group(all P
