The n-Hexane, ethylacetate, and butanol fractions from Hydnocarpi Semen enhanced wound healing in a mice ulcer model.

Abstract
Our previous report showed that Hydnocarpi Semen (HS) extract has wound repair activity at ulcer lesion in diabetic mice. In this study, fractions of n-Hexane, ethylacetate (EtOAc), and butanol (BuOH) from HS crude extract were evaluated for their wound healing activity by using in vivo diabetic ulcer models and in vitro acute inflammation model. Although n-Hexane and EtOAc fractions promote wound healing in mice with ulcer, the BuOH fraction exhibited the most potent wound healing activity and the wound area score significantly decreased after treatment of BuOH fraction even at dose of 2 mg/kg. BuOH fraction stimulated macrophages to increase the production of nitric oxide (NO) and TNF-α. The BuOH fraction also enhanced the production of TGF-β and VEGF, which were involved in fibroblast activation and angiogenesis. The mRNA expression and activation of MMP-9 were increased by three fractions and the activity was higher in BuOH fraction-treated group compared to the other groups. The mechanism that the HS helps to promote healing of diabetic ulcer is possibly associated with the production of TNF-α, a proinflammatory cytokine, as well as the secretion of VEGF, TGF-β, and MMP-9, which were involved in proliferation of capillaries and fibroblasts. These results suggest that HS can be a new candidate material for the treatment of wound in skin ulcer.
