Abstract
Background: Zingiber zerumbet rhizome ethyl acetate extract (ZZRE) has the potential to be developed as a wound-healing agent with its profound anti-inflammatory property. Objective: This study was conducted to evaluate the wound healing effects of 5% ZZRE on open wound in rats. Materials and Methods: Wistar rats (n = 90) were divided into three groups, negative control (treated with PBS), positive control (treated with solcoseryl gel), and 5% ethyl acetate extract of Z. zerumbet, respectively. Wounds were induced on the rat's dorsal surface on day 0. Measurements of wound closure, total protein, uronic acid, hexosamine, cathepsin B, hydroxyproline, and histological observations were conducted on the wound tissues. Results: ZZRE-treated group showed increment in wound closure, protein, and hydroxyproline level. The uronic acid and hexosamine levels of ZZRE-treated wounds significantly increased on the 3rd day (P Abbreviations Used: ZZRE: Zingiber zerumbet rhizomes extract, PDGF: Platelet-derived growth factor, TGF-β: Transforming growth factor-beta, PBS: Phosphate-buffered saline, EDTA: Ethylenediaminetetraacetic acid
