The decoction of the stem barks from Bowdichia virgilioides KUNTH is a folk remedy used to treat inflammatory disorders in Latin American and Brazil. In the present study, the wound healing activity of aqueous extract of the stem bark from B. virgilioides, called AEBv, was evaluated by the rate of healing by wound contraction and period of epithelization at different days post-wound using the wound excisional model. On day 9, the AEBv-treated animals exhibited significative reduction in the wound area when compared with controls. In wound infected with S. aureus, the AEBv significantly improved the wound contraction when compared to the saline-treated mice. The histological analysis showed that AEBv induced a collagen deposition, increase in the fibroblast count and few inflammatory cells than compared to saline-treated group. The expression of collagen type I was increased in the group treated with AEBv as indicated by immunohistochemical staining. In vitro, the AEBv was effective only against S. aureus but not against P. aeruginosa. Together, the results of this study demonstrate, for the first time, the healing and antimicrobiological effects of aqueous extract of the stem bark from B. virgilioides in the therapy of skin wounds.

Background The present study aimed to prepare effective silk derived formulations in combination with plant extract (Aloe vera gel) to speed up the wound healing process in diabetic mice. Methods Diabetes was induced in albino mice by using alloxan monohydrate. After successful induction of diabetes in mice, excision wounds were created via biopsy puncture (6 mm). Wound healing effect of silk sericin (5%) and silk fibroin (5%) individually and in combination with 5% Aloe vera gel was evaluated by determining the percent wound contraction, healing time and histological analysis. Results The results indicated that the best biocompatible silk combination was of 5% silk fibroin and 5% Aloe vera gel in which wounds were healed in 13 days with wound contraction: 98.33 ± 0.80%. In contrast, the wound of the control group (polyfax) healed in 19 day shaving 98.5 ± 0.67% contraction. Histological analysis revealed that the wounds which were treated with silk formulations exhibited an increased growth of blood vessels, collagen fibers, and much reduced inflammation. Conclusion It can be concluded that a combination of Bombyx mori silk and Aloe vera gel is a natural biomaterial that can be utilized in wound dressings and to prepare more innovative silk based formulations for speedy recovery of chronic wounds.

Objective: The current research is an attempt to evaluate the wound healing activity of Electrohomeopathic drug Green electricity (GE) in Wistar rats. No data have been reported till date on the wound healing effect of GE. Hence the present research focuses on the scientific investigation of the wound healing activity of GE in rats. Methods: Excision and incision wounds were inflicted upon albino rats. In the excision wound model, the wound contraction, Scar residue, area and time of complete epithelization were measured subsequently on day 0, 3,6,9,12,15, 18 and 21 after inflicting the wound. Wound contraction was calculated as a percentage change in the initial wound size. In the incision wound model, the tensile strength was measured on the 10th post wounding day. Results: It was noted that the effect produced by the GE Showed significant wound healing (p<0.01) in all wound models when compared to the control group. In the case of the excision model, GE statistically increases the wound contraction rate and in the case of the incision model GE showed high tensile strength as compared to the control group. In both cases the epithelization period was significantly decreased as compared to control. Almost 100% wound protection was achieved by GE in 21 d as compared to control. Conclusion: GE (ointment) showed significant wound healing activity (p<0.01) in both the excised wound model and incision wound model in rats.

The Stability

Bromelain is a mixture of proteolytic enzymes presence in all tissues of pineapple (Ananas comosus). It is known for clinical use as debridement for burn treatment. However, it is easily degraded by light, high temperature and pH. Nanoemulsion of bromelain is promising to increase its stability. In this study, we investigated the nanoemulsion of bromelain and its formulation into gel preparation in order to increase its efficacy for the burn treatment. Spontaneous or self-nanoemulsifying was applied to form nanoemulsion of bromelain (NEB). Bromelain was incorporated in various types of oil phase i.e virgin coconut oil (VCO), olive oil, vitamin E acetate and combination of both vitamin E acetate and VCO. Cremophor RH 40 was used together with polyethyleneglycol 400 to reduce oil-water interface tension. The stability of NEB in different oil phases was evaluated including particle size, polydispersity index, zeta potential, enzymatic activity and nanoemulsion morphology. Further, the most stable NEB was incorporated into hydrophilic gel matrix. An in vivo evaluation was carried out in hot plate-induced burn skin of New Zealand rabbit. Treatment of wounds was given by applying the preparations: NEB and the nanoemulsion bromelain-CMC gel (GKNB), using a standard protocol. As a control, untreated rabbit burned skin was provided. The efficacy of NEB was evaluated by observing wound contraction, eschar score, erythemic score, pus score and edema. After 14 days of storage, nanoemulsion using vitamin E acetate was found to be the most appropriate formula to encapsulate bromelain with good physical and chemical stabilities. This formula shows clear visual appearance with globule diameter of 74.37 nm, narrow size distribution, high loading efficiency of 97.96 %, and ability to maintain the enzymatic activity of bromelain compared to gel preparation using corresponding bromelain nanoemulsion. The vitamin E acetate nanoemulsion system shows better reduction in wound contraction until the 14th day of observation as well as other relevant parameters for wound healing effects. Taken together, bromelain formulated with the vitamin E acetate nanoemulsion improved the stability of bromelain and showed better activity to heal burnt skin on the animal model tested. The gel matrix retained the release of bromelain resulting in lower wound healing effect but it may have prolonged activity.
