Abstract :

Ischemia reperfusion is a Cellular damage that occurs on return of blood to the ischemic tissue. In this study the preventive effects of magnesium sulfate on complications induced by ischemia reperfusion was investigated.  In this study, 25 male Wistar rats were used randomly divided into 5 groups of 5.The Sham group: The group has not received any medication and after only a week, blood sample was collected. The Control group (IR): The group has not received any medication before ischemia reperfusion. After a week the abdominal cavity was opened and a renal vessel were closed with non-traumatic forceps and after 45 min were released, then 8 hours later blood sample was collected. The third group (25mg/kg): This­ group was administrated orally with magnesium sulfate (25 mg/kg) for a week and after a week the abdominal cavity was opened, and renal vessels were closed with non-traumatic forceps and after 45 min were released then 8 hours later blood sample was collected. The forth group (50mg/kg): The group was administrated orally with magnesium sulfate(50mg/kg) for a week, and after a week the abdominal cavity was opened, and renal vessels  were closed with non-traumatic forceps and after 45 min were released, then 8 hours later, blood sample was collected. The fifth group (100mg/kg): The group was administrated orally with magnesium sulfate (100mg/kg) for a week, and the abdominal cavity was opened after a week, and renal vessels were closed with non-traumatic forceps and after 45 min were released, then 8 hours later, blood sample was collected.  At day zero (before drug administration) and after the end of ischemia-reperfusion and 8 hours later, blood samples were collected and serum creatinine and BUN levels were examined. Data was analyzed statistically (P<0.05). The result of this study shows that serum BUN and creatinine levels, in pretreated groups with Magnesium sulfate in contrast with untreated groups are lower. Consequently Magnesium sulfate could prevent ischemia-reperfusion induced injury to the kidney.
