The soluble proteins extracted from the latex of Calotropis procera (LP) have been shown to powerfullyameliorate different inflammatory disorders such as arthritis, cancer and sepsis. In this study, we devel-oped a polyvinyl alcohol-based membrane as an LP delivery system and determined the efficacy of LP intissue remodeling and healing upon topical treatment in mice. Aqueous polyvinyl alcohol (PVA, 1%, w/v)solution was mixed with LP (0.2% or 1%) while stirring to obtain a biomembrane, which was then appliedto wounds. PVA and LP-containing PVA membranes were structurally characterized and standardized byinfrared absorption spectroscopy and thermogravimetry. Wound healing parameters included time ofhealing progress and tissue remodeling (fibroplasia and collagen). LP-containing PVA membrane (0.2%and 1%), but not PVA membrane, significantly accelerated wound healing through faster neo-tissue for-mation. This process was accompanied by intensified fibroplasia and collagen deposition as revealed bymicroscopic analyses. It is therefore concluded that topical application of LP on wounds stimulates thehealing process and that the use of PVA membranes to carry LP is a reliable approach for topical deliveryof pharmacologically active proteins.
