Wound Healing Activity

The present experimental study was designed to evaluate the wound healing activity of methanolic extract of Smilax wightii A. DC. on incision and excision wound models in Wistar albino rats. The parameters studied were wound breaking strength, wound contraction area, epithelialization period, granulation tissuewet, dry weight and hydroxyproline content in incision wound model, percentage of wound contraction and period of epithelialization in excision wound model. The rats were administered topically with 100mg/kg b.wt. (low dosage), 200mg/kg b.wt. (moderate dosage) and 500mg/kg b.wt. (high dosage) of methanolicextract of Smilax wightii (MESW). The activity of the extract treated groups were compared with that of the control 1% Spirit. Framycetin sulphate 0.2% w/w was used as the standard drug. In incision wound model, there was a significant increase in the wound breaking strength in all the experimental groups treated withMESW than that of the control. Similarly, significant (P<0.001) decrease in wound contraction area and period of epithelialization were also observed in the test group animals treated with MESW and the standard drug treated groups when compared to that of the control. , a significant increase was observed in granulation tissue wet and dry weight and hydroxyproline content in the test groups treated with MESW compared to the control. In exicision wound model, there was a significant increase (P<0.01) in the percentage of wound contraction and decrease in period of epithelialization in the experimental groups treated with 200mg/kgb.wt. (moderate dosage) and 500mg/kgb.wt (high dosage) of MESW. The extract treated groups showed significant improvement in all the wound healing parameters of incision, and excision wound models.

Objective: Wound healing potential of polyherbal ointment prepared from Cordial oblique Willd., Dentophote falcate (L.f) Ettingsh., and Vigna radiate Linn. has been evaluated, Preclinical studies were carried out using albino rats as experiment models.Methods: Animals were divided into 6 groups, each groups comprising of 6 rats. Group I, II and III are normal excision wounded rats that were categorized as normal untreated, polyherbal ointment treated and standard ointment treated respectively. Groups IV, V and VI were induced with diabetes using alloxan monohydrate (150mg/kg bw; ip single dose) and grouped into diabetic untreated, polyherbal ointment treated and standard ointment treated respectively. The polyherbal ointment was prepared by using aqueous extracts of plants in equal proportion with simple ointment base (15% w/w). The Physical, Biochemical and enzymatic parameters studied were rate of wound contraction, ascorbic acid, hydroxyproline, hexosamine, SOD, LPO, serum protein, granulation tissue protein, serum glucose, DNA, RNA, platelet and WBC.Results: The excision wounded animals treated with polyherbal ointment showed a higher rate of contraction and epithelialization during the treatment period. Group II showed 100% and group V showed 90% wound contraction at the end of experimental period. Hydroxyproline, hexosamine, ascorbic acid, tissue protein, DNA, RNA levels and SOD activity were increased significantly (p<0.05), LPO, platelet and serum protein level were decreased with polyherbal ointment treated groups compared to control and standard groups.Conclution: The present study substantiates the traditional claims of plants prepared as polyherbal ointment possessing significant wound healing promoting activity and provides scientific evidence to the ethno medicinal property of plants in healing wounds.Keywords: Wound healing, Polyherbal ointment, Hydroxyproline, Hexosamine, Excision wound, Cordia obliqua Willd., Dentophote falcate (L.f)Ettingsh., Vigna radiata Linn.

The study was designed to evaluate the effects of hydromethanolic extract of tuberous root of M. jalapa and its terpenoid and flavonoid fractions on cutaneous wound healing in Wistar Albino rats. The hydromethanolic extract was subfractionated by sequential extraction in solvents (moderately nonpolar to polar). The extract and its (terpenoid and flavonoid) fractions were used for cutaneous wound healing studies by using excision wound model on rat. Their effects on wound contraction rate, biochemical and histological changes, and expression of growth factors such as collagen 3A, basic fibroblast growth factor, and vascular endothelial growth factor were investigated. The results indicated that flavonoid treated group showed significant decrease (P<0.05) in antioxidant enzyme level as compared to control in wound healing process, whereas terpenoid fraction showed significant increase (P<0.05) in expression of growth factor levels but regeneration and remodeling stages were delayed due to formation of thicker ulcus layer and also there were no hair follicle-like blood capillaries formation which ultimately may lead to formation of hypertrophic scar of wound. Therefore, from this study, it can be concluded that terpenoid fraction prolongs proliferation phase and hence may have tendency to convert the wound into hypertrophic wound.

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.

Objective: The objective of the present research was to investigate the wound-healing potency of solid lipid nano particles of Hibiscus rosa sinensis extract. Crude herbal extracts and rudimentary formulations containing herbal extracts are good for demonstrating the feasibility of the concept; however, such formulations suffer with poor oral bioavailability and variability within groups of subjects. Converting herbal extracts into novel drug delivery systems may prove effective in addressing some of these problems. Methods: In the present study an attempt was made to develop Hibiscus rosa sinensis extract loaded solid lipid nanoparticles (HSLNs) using lipids glycerol monostearate (GMS) or beeswax. The prepared HSLNs were characterised for their size, surface charge and morphology. The optimized HSLNs were incorporated into Carbopol gel and tested for wound healing activity in male Wistar albino rats using excision wound model. Results: HSLNs of ~175 nm in size carrying negative charge were obtained with the optimised procedure using beeswax. The shape of the HSLNs was nearly spherical. The HSLNs (10 mg/ml) treated wounds healed much faster compared to raw crude extract and healing was comparable to marketed preparation. Conclusion: It is concluded that converting crude herbal extracts into SLNs can be an effective way to enhance the effectiveness of herbal extracts and their in vivo activity.
