Background and Objective: Cyclooxygenase 1 and 2 activities on arachidonic fatty acids of cell membrane produces prostaglandins which involved in inflammatory processes. This study was done to evaluate the effect of hexanic and hydroalcoholic extract of Cannabis sativa flowers on inflammatory paw edema in rats. Methods: In this experimental study, 56 male Wistar rats were allocated into the control, sham, sodium salicylate (300mg/kg/bw) and hydroalcoholic extract of heated flowers in 1, 10 and 50 mg/kg/bw, hydroalcoholic extract of unheated flowers in 50mg/kg/bw and hexanic extract of heated flower in 50mg/kg/bw, intraperitonally. 30 minutes after injection, inflammatory edema volume due to sub plantar injection of formalin (0.05 ml, 2.5%) measeared using plethysmometric method. Results: Intraperitonally injection of 50mg/kg/bw, of hydroalcoholic and hexanic extracts of heated flowers significantly reduced in inflammatory paw edema induced by formalin (P<0.05). Also, 50mg/kg/bw, hydroalcoholic extract of unheated flowers reduced the inflammatory paw edema in comparison with heated extracts (P<0.05). Conclusion: Hydroalcoholic extract of heated flowers decreased inflammation-induced paw edema in dose-dependent manner. The extract of unheated flowers, leads to more reduction of the inflammatory paw edema in comparison to heated flower extract, it can be due to carboxylated cannabinoid present in the hydroalcoholic extract of unheated flowers.

Background and Objective: Stroke and cerebral ischemia are the second leading causes of death in the world. Currently, there are limited therapeutic interventions for patients with ischemia / reperfusion. This study was performed to determine the protective effect of aerobic exercise and adenosine on changes in inflammation mediators after transient ischemia of common carotid arteries in male Wistar rats.
Methods: In this experimental study, fifty male Wistar rats were randomly allocated into to 5 groups: control, cerebral ischemic control, aerobic exercise + cerebral ischemia, adenosine + cerebral ischemia and aerobic exercise + adenosine + cerebral ischemia. Ischemia was performed by blocking the common carotid artery for 45 minutes after a period of exercise and injection of adenosine. Neuronal structure was examined by Nissel tissue staining. The expression of NGF and Glutamate genes were measured in CA1 region of hippocampal tissue samples.
Results: Cell death was increased in neurons in the CA1 region of the hippocampus in the ischemia / reperfusion group, While a significant reduction in cell death in the adenosine + ischemia / reperfusion and aerobic exercise + ischemia /reperfusion groups was due to adenosine administration and aerobic exercise (P<0.05). NGF and glutamate gene expression in the adenosine + ischemia/reperfusion and adenosine + aerobic exersice + ischemia/reperfusion groups significantly increased and reduced compared to the ischemia/reperfusion control, respectively (P<0.05).
Conclusion: Co-administration of adenosine combined with aerobic exercise increase the protective effect of aerobic exercise on improving the neuronal damage after ischemic / reperfusion.
