Abstract
Artery occlusion of an organ results in ischemia. When the occlusion is opened and blood flow reinstated there will be tissue injuries identified as reperfusion-induced ischemia (RII). It has been suggested that cannabinoids (CBs) may be involved in the RII. In this study, we assessed the effect of different doses of anandamide analogs and CB receptor agonists: arachidonylcyclopropylamide (ACPA, a CB1 agonist) and JWH133 (a CB2 agonist) in the RII of the mouse kidney. Three doses (0.2, 1 and 5mg/kg, i.p.) of ACPA or JWH133 were used 30min prior initiation of RII. Kidneys were removed 2 and 24h following RII and checked histologically for the grading of ischemic injury. Appropriate control groups were used as well. RII produced lesion comparable with that of ischemia. Different doses of ACPA or JWH133 prevented RII-induced lesions. It is suggestive of the CB system involvement in the kidney RII in mice.
