The Effect Of Quercus Coccifera L. Extract On The Necrosis Of Random-Pattern Skin Flaps In Rats

Abstract

Aim: Ischemia-reperfusion injury is an important cause of flap loss. We investigated effects of Quercus coccifera L. extract known to have anti-oxidant and anti-inflammatory activity on skin flap viability. Methods: Eighteen Wistar rats were used. Random-pattern skin flaps, 9x3 cm in size, were applied on rats back and then the rats were divided into three groups. Following surgery 2 cc of nitrofurazone cream and 2 cc of Q. coccifera L. water extract were applied daily in groups 2 and 3, respectively. Group 1 received no treatment after surgery. The percentage of necrosis on the flaps was calculated and histopathological examination of the tissue samples was made on day 7. Results: The mean percentage of necrosis was 44.7%, 42.5% and 21.8% group 1, 2 and 3, respectively. The percentage of necrosis was statistically significantly lower in group 3 than in groups 1 and 2 (p<0.001 and p<0.00, respectively). Neutrophil score was found to be significantly lower in group 3 than in groups 1 and 2 (p=0.002 and p=0.002, respectively). Conclusions: Necrosis of skin flaps was decreased through application of Q. coccifera extracts
