Topical co-administration of Teucrium polium hydroethanolic extract and Aloe vera gel triggered wound healing by accelerating cell proliferation in diabetic mouse model.

This study was conducted to evaluate the effect of co-administration of ointments prepared from Teucrium polium hydroethanolic extract (TPEO) and Aloe vera gel (AVGO) on excisional wound healing in a diabetic mouse model. Following the induction of diabetes and circular excisional wound (7 mm), the mice were divided into six groups, namely (Ⅰ) control mice treated with mupirocin (as a standard drug), (Ⅱ and Ⅲ) the mice treated with 5 and 10 % TPEO, (Ⅳ and Ⅴ) the mice treated with 5 and 10 % AVGO, and (Ⅵ) the mice treated with a combination of 5% TPEO and 5% AVGO (TPEO+AVGO). To investigate the wound area, we further evaluated the wound area ratio, histological analysis and the serum levels of tissue antioxidant capacity (TAC) and malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β), immunohistochemistry staining for vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF-1), glucose transporter-1(GLUT-1) and collagen type 1 and mRNA expression levels for VEGF, IGF-1, GLUT-1 and fibroblast growth factor-2 (FGF-2). The results showed that administration of the ointments, especially in combination form, shortened the inflammatory phase and reduced the levels of tissue MDA, TNF-α and IL-1β compared to mupirocin group (P < 0.05). Moreover, fibroblasts proliferation, collagen deposition, VEGF, IGF-1, GLUT-1-positive cells and level of TAC, and expressions of VEGF, IGF-1, GLUT-1 and FGF-2 were significantly ...
