Oil mixes omega 9, 6 and 3, enriched with seaweed, promoted reduction of thermal burned modulating NF-kB and Ki-67

ABSTRACT

PURPOSE: To examine the effects of the oil mixes (-9, -6 and -3) in rats subjected to thermal burn. It was also aimed to assess whether the sources of 3 would interfere with the effect of such mixes on the thermal injury.METHODS:Thirty-six rats distributed into five groups burned + water, burned + isolipid mix, burned + oil mix 1 (ALA), burned + oil mix 2 (ALA + EPA + DHA of fish) and burned + oil mix 3 (ALA + DHA from seaweed). The thermal injury was involving total thickness of skin. After the burns animals received the oil mixes for seven days. The lesions were evaluated by immunohistochemistry.RESULTS:Animals receiving mix 3 showed a smaller extension of the thermal injury as compared to those that were supplemented with other oils mixes. Expression of Ki-67 in the receiving Mix 3 increased as compared to all the other groups. Animals supplemented with mix 3 were able to inhibit NF-B in injured tissue.CONCLUSION:Rats received oil mix in which the source of 3 (ALA+DHA of seaweed) showed inhibition of NF-B, increase in cell proliferation, and reduction the extension of thermal lesion.(AU)
