Crassocephalum crepidioides (Benth.) S. Moore. has been used to treat small wounds by minority people in Lam Dong, Vietnam. However, there has been no scientific evidences about its wound healing activity. This study is aimed at evaluating the wound healing activity of Crassocephalum crepidioides hydroethanolic extract via its antioxidant and anti-inflammation activities and healing capability on a mouse excision wound model. Crassocephalum crepidioides hydroethanolic extract (CCLE) at a dose of 50 mg/kg/day reduced the wound closure time about 3.5 days, compared to vehicle treatment. The granulation tissue on day 7 after surgery from the treated group showed a 2.8-fold decrease in the density of inflammatory cells, 1.9-fold increase in the fibroblast density, and a higher number of blood vessels. Real-time PCR analysis indicated that the mRNA expression level of NF-κB1 and TNF-α mRNA in CCLE-treated wounds decreased by 4.6 and 3.3 times, respectively, while TGF-β1 and VEGF were found to increase by 3.3 and 2.4 times, respectively. Our experimental data provided proofs of Crassocephalum crepidioides leaf wound healing activity due to its antioxidant, anti-inflammation, fibroblast proliferation, wound contraction, and angiogenesis effects.

Background. Medicinal plants play indispensable roles to treat various ailments. Acanthus polystachyus is one of the medicinal plants used traditionally for treatment of wounds. However, there were no scientific reports documented so far on the wound healing activities of this plant. Thus, the present study provides a scientific evaluation for the wound healing potential of the crude extract of A. polystachyus leaves. Methods. The crude extraction was carried out using 80% methanol. The crude extract was prepared in 5% (w/w) and 10% (w/w) ointment and evaluated for wound healing activity using excision, infected, and incision wound models in Swiss albino mice. Results. Both 5%  and 10% (w/w) ointments significantly reduced period of epithelialization and increased wound contraction rate and tensile strength compared to the negative control group (P < 0.05). The wound healing activity of 10% (w/w) ointment treated group was greater than 5% (w/w) and nitrofurazone ointment treated groups in S. aureus infected wound model. Conclusion. These results demonstrate that the crude extract of A. polystachyus leaves possesses wound healing activities. This justifies the traditional claimed use of the plant for treating uninfected and infected wounds caused by S. aureus.

The present study is aimed at evaluation of phytosomal gel of the petroleum ether extract of root bark of Onosma echiodes for wound healing activity in rats. Extract of root bark of O. echioides was standardized by isolated naphthoquinone dimer using HPTLC. Phytosomes (equivalent to 2% w/w of naphthoquinones) of the standardized extract were prepared by thin film hydration technique. The wound healing efficacy of the formulation was evaluated in rats by inflicting excision and incision wounds followed by treatment of the wounds topically. The parameters evaluated for healing included determination of breaking strength and tensile strength of healed skin for incision model and percentage wound contraction, hydroxyproline content, granulation tissue free radicals and catalase in excision wound model. The formulation treated group showed a significant healing (p<0.005) of both the excision and incision wounds with respect to wound contraction and tensile strength respectively, as compared to vehicle treated group. The oxidative stress of the granulation tissue was also found to be reduced as indicated by reduced lipid peroxidation and increase in catalase activity. The phytosomal gel of O. echioides effectively exhibited wound healing effect.

Deep Tissue Injury

Background: Chronic inflammation and lack of angiogenesis are the important pathological mechanisms in deep tissue injury (DTI). Curcumin is a well-known anti-inflammatory and antioxidant agent. However, curcumin is unstable under acidic and alkaline conditions, and can be rapidly metabolized and excreted in the bile, which shortens its bioactivity and efficacy. Objective: This study aimed to prepare curcumin-loaded poly (lactic-co-glycolic acid) nanoparticles (CPNPs) and to elucidate the protective effects and underlying mechanisms of wound healing in DTI models. Methods: CPNPs were evaluated for particle size, biocompatibility, in vitro drug release and their effect on in vivo wound healing. Results : The results of in vivo wound closure analysis revealed that CPNP treatments significantly improved wound contraction rates (p<0.01) at a faster rate than other three treatment groups. H&E staining revealed that CPNP treatments resulted in complete epithelialization and thick granulation tissue formation, whereas control groups resulted in a lack of compact epithelialization and persistence of inflammatory cells within the wound sites. Quantitative real-time PCR analysis showed that treatment with CPNPs suppressed IL-6 and TNF-α mRNA expression, and up-regulated TGF-β, VEGF-A and IL-10 mRNA expression. Western blot analysis showed up-regulated protein expression of TGF-β, VEGF-A and phosphorylatedSTAT3. Conclusion: Our results showed that CPNPs enhanced wound healing in DTI models, through modulation of the JAK2/STAT3 signalling pathway and subsequent upregulation of pro-healing factors.

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.

Previous studies proved the wound healing potential of Tilvadi Ghrita (TG) and Durva Ghrita (DG) on normal wounds, so this study was conducted to investigate wound healing activity of TG and DG on diabetic wound model in rats. Forty-eight adult female Wistar rats in eight groups were used. Alloxan was used to induce diabetes in diabetic groups. Excision wound was made on the dorsal shaved surface of rats, and then Framycetin sulfate cream (FSC) 10%, TG and DG were applied in control and treatment groups. While in normal control and diabetic control groups, no medication was done. Wound photographs were taken on alternative days to evaluate wound healing. Percentage wound contraction, the effect on wound size, and epithelization period parameters were studied. Ghritas were investigated for their preliminary phytochemicals, Physico-chemical properties, skin irritation test, and wound healing activity in normal and diabetic rats. Data were expressed as mean ± SEM and analyzed using Two-way ANOVA followed by Bonferroni’s multiple range test. Studies revealed that TG and DG do not cause any harmful skin reactions, so both ghritas were found to be safe for topical application. Both formulations showed better and fast healing as compared to untreated normal and diabetic control groups. After comparative investigation, it was observed that DG possesses higher wound healing potential in normal and diabetic groups with comparison to TG. Wound healing action in normal and diabetic wounds, it endowed due to the presence of different phytoconstituents reported in the literature and proved to be beneficial in the management of wounds.

The antioxidant activity was performed by DPPH Scavenging activity method and Hydrogen peroxide scavenging activity method. Ascorbic acid was taken as standard in both methods. DPPH and Hydrogen peroxide scavenging activity methods of 100µg/ml extracts shows better % inhibition as compared to control and 50 µg/ml extracts. In DPPH Scavenging activity % inhibition of 100µg/ml methanolic extracts was 60.72% and in Hydrogen peroxide scavenging activity it was found to be 26%. Wound healing activity was performed by Incision wound model and Excision wound model. In incision wound healing model, the tensile strength of the 4% test group and the Neosporin ointment treated group were comparable to each other. Tensile strength of 2% extract ointment showed lesser 3.38 gm/mm2 but significant increase in tensile strength compared to the control group 2.91 gm/mm2. The tensile strength of 4% test group was found to be 3.44 gm/mm2. Thus both concentrations of the extract as well as the standard drug showed a significant increase in tensile strength on the 9th day. In excision models the animals treated with the 4% w/w KPME ointment were shown to healed completely as compared to 2%w/w which was also at the complete healing stage as compared to control treated and the standard drug (Neosporin) treated group. The epithelization period of standard group and treated group was less in comparison with that of simple ointment base treated groups. The percentage of wound contraction was much more with the 4% w/w extract was similar to that of Neosporin treated group. 2%w/w treated group of animals showed significant wound contraction. In antimicrobial activity, both antibacterial and antifungal potentiality was evaluated. In mic of antibacterial methanolic extract of Kigelia pinnta inhibit strains of E.coli and strain of Shigella boyelii, Salmonella aureus and Baccilus subtitis were found to be completely resistant. In mic of antifugal activity, all the fungal strain were inhibited by methanolic extract of Kigelia pinnata. These findings may provide a lead for further investigation of the overall pharmacological aciotns of Kigelia pinnata methanolic extract in more appropriate model.
