Stroke is a serious cerebrovascular disease that causes post-stress depression and death. Stress and inflammation have pivotal roles in the induction of the disease. Several drugs and agents have been used for the treatment of disease, but their uses are faced with limitations owing to their side effects. Natural agents are more efficient for the treatment of stroke due to lower toxicity and their pharmaceutical properties. Sake yeast or Japanese rice wine is an antioxidant compound that could be used to treat stroke and post-stress depression. This study evaluates the effects of sake yeast on depressive-like behaviors, oxidative stress and inflammatory parameters in a rat model of global cerebral ischemia/reperfusion. Rats were divided into four groups, including 1) control: without bilateral common carotid artery occlusion (BCCAO) and sake supplement, 2) Ischemia group: rats induced with BCCAO and lack of therapeutic supplement, and 3 and 4) Ischemia + sake groups: rats induced with BCCAO and treated with 25 and 50 mg/kg sake yeast, respectively. Depressive-like behaviors antioxidant enzymes activities were assessed. The induction of stroke increased oxidant status, inflammatory parameters, and depressive-like behaviors, while the administration of sake could decrease inflammation, depressive-like behaviors, and oxidant status and increase antioxidant enzymes. The yeast could be used as a supplement in combination with other drugs to treat stroke.
