CUMS model was induced by exposing rats to various mild stressors daily for 5 weeks. The extract of propolis (100 mg\/kg\/day) was administered orally to propolis-treated groups for 5 weeks. The depression-like behaviours were assessed with the forced swimming test (FST). Chronic stress resulted in increased immobility response in FST and elevated serum corticosterone levels. Thoracic endothelial functions and expressions of endothelial nitric oxide synthase (eNOS), tumor necrosis factor-alpha (TNF\u03b1), interleukin-1beta (IL-1\u03b2), Heme oxygenase-1 (HO-1) and superoxide dismutase (SOD) level were assessed.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Key findings<\/jats:title>\n                  <jats:p>Compared to control group, stress group exhibited a significant decrease in endothelium-dependent relaxations, and eNOS, SOD and HO-1 expressions, whereas a significant increase in the thoracic expressions of TNF\u03b1 and IL-1\u03b2.
