Abstract

Diabetes can delays wound healing by prompting long-term inflammation; delayed maturation of granulation tissues and inhibition of angiogenesis. Isoeugenol a phenylpropene; present in many plants including calamus, savory, basil, clove, tuberose, jonquil, nutmeg, sandalwood, dill seed, mace, gardenia, petunia etc. It can also be produced by isomerization of eugenol, present significant amounts in clove, pimento, bay leaf, and cinnamon. Isoeugenol used as a flavoring agent, in nonalcoholic drinks, baked foods, and chewing gums. In the present study, we investigated the effects of topical administration of Isoeugenol (50mg/kg and 100mg/kg; daily in 200 μl acetone) on excisional wound in diabetic swiss albino mice. The five groups of Swiss albino mice were used (10 mice per group): group 1, the non-diabetic (normal control; NM); group 2, wound in non-diabetic mice (N+W); group 3, wound in diabetic mice (D+W); group 4, Isoeugenol 50mg/kg treated wounds in diabetic mice (D+W+L50); group 5, Isoeugenol 100mg/kg treated wounds in diabetic mice. Wound size was recorded on every third day and after 14 days of treatment, the heparinised whole blood and the wound tissue of all the groups was collected and tested. Isoeugenol treated mice showed a significant decrease in wound size, pro-inflammatory markers and chemokine expression. Furthermore, histopathological examination showed complete re-epithelisation, decreased inflammatory cells and presence of granulation tissue in the Isoeugenol treated mice. These characteristics suggest a beneficial role of Isoeugenol in helping rebalance the wound environment in diabetes and therefore promote healing.
