OBJECTIVE
To evaluate the effects of the Andiroba (carapa guianensis) oil on liver function in rats subjected to normothermic ischemia / reperfusion injury.
METHODS
we divided 12 Wistar rats into two groups: saline (n = 6) and Andiroba (n = 6). The Andiroba group was treated with Andiroba oil (0.63 ml/kg orally) for seven days before surgery. Ischemia was induced by occlusion of the blood supply to the lateral and median lobes of the liver, using vascular clips, in both groups, for 45min, followed by reperfusion for 60 minutes later. We analyzed dosages of AST, ALT, Gamma-GT, and liver biodistribution of 99mTc phytate.
RESULTS
There was no significant difference in the percentage of radioactivity / gram of tissue (%ATI/g) in the right lobe of the saline group (17.53 ± 2.78) compared with the Andiroba group (18.04 ± 3.52) p = 0.461, the same occurring in the%ATI/g of the left lobe of the liver when the two groups were compared (p = 0.083). In the saline group, the%ATI/g was significantly higher in the non-ischemic right hepatic lobe (17.53 ± 2.78) when compared with the left lobe (5.04 ± 0.82) that suffered ischemia / reperfusion (p = 0.002). Significant differences also occurred when comparing the right (18.04 ± 3.52) and left (7.11 ± 1.86) lobes of the animals of the Andiroba group (p = 0.004). There was no significant difference in dosages of AST, ALT and Gamma- GT when comparing the two groups (p > 0.05).
CONCLUSIONS
Andiroba oil did not contribute to the protection of liver function in a rat model of liver injury induced by normothermic ischemia and reperfusion.
