In diabetes, impaired wound healing and other tissue abnormalities are considered major concerns. The aim of the present study was to assess the wound-healing activity of methanolic extracts of the extract of Lycium depressum leaves. A total of 60 healthy male Wistar diabetic rats weighing approximately 160 to 180 g and 7 weeks of age were randomized into 10 groups for incision and excision wound models: sham surgery group (SHAM), including creation of wounds and no treatment; base formulation group (FG) with creation of wounds and application of base formulation ointment; treatment group 1 (TG1) with 1 g of powder extract of the plant material in ointment; treatment group 2 (TG2) with 2 g; and treatment group 4 (TG3) with 4 g of powder extract of the plant material in ointment. A wound was induced by an excision- and incision-based wound model in male rats. The mature green leaves of L depressum were collected and authenticated. Extractions of dried leaves were carried out. For wound-healing activity, the extracts were applied topically in the form of ointment and compared with control groups. The healing of the wound was assessed based on excision, incision, hydroxyproline estimation, and biomechanical and biochemical studies. The extract of L depressum leaves enhanced wound contraction, decreased epithelialization time, increased hydroxyproline content, and improved mechanical indices and histological characteristics in treatment groups compared with SHAM and FG ( P < .05). These findings permit the conclusion the extract of L depressum benefits parameters of wound healing in a diabetes induced model

AbstractBackgroundDiabetic wound are the major problem of society because of its delay healing of wound in hyperglycemia patient. The target of this study need to know the gallic acid compelling synergistically wound healing in diabetic animals as it is available in fruit extract or is more effective in given pure form in diabetic animals.MethodsThe wound healing effects of fruit extract Terminalia bellerica Roxb. and gallic acid were evaluated in experimentally induced hyperglycemic animals. In this investigation, excision and dead space wound models were used. The contraction wound %, re-epithelialization days, area of scar, histopathological examination of tissue, hydroxyproline level and weight of tissue granuloma were evaluated in this study.ResultsTerminalia bellerica fruit extract (400 mg/Kg) and gallic acid (200 mg/Kg) have been ingested by orally in streptozotocin induced diabetic rats. They were founded significantly (p<0.05) improved percentage wound contraction and decreased the size of scar area and days of re-epithelialization in excision wound model. Also, they were improved the level of hydroxyproline level in diabetic rats as compared to diabetic control group in dead space wound model. Standard drug vitamin C was also founded significantly improved wound healing activity in rats. These results suggested that treated groups accelerated wound healing activity in diabetic rat.ConclusionsThe observations and results obtained in the present study indicated the wound healing efficacy of fruit ethanolic extract and gallic acid in diabetic animals. Yet, the wound healing effect was increasingly reported with gallic acid.

Epidermal stem cells are essential in wound healing, but their amount and activity are decreased in diabetes which contributes to the impaired healing. This study evaluated the efficacy of amniotic membrane loading epidermal stem cells in the management of impaired wound in diabetes. Epidermal stem cells derived from SD rats were isolated, cultured, identified and labled with BrdU in vitro. The wound model of diabetic rats were established, then amniotic membrane loading labled BrdU epidermal stem cells were implanted to impaired wound. The results showed that wound healing rate in amniotic membrane loading epidermal stem cells was significantly higher than that in control groups 14 days after treatment. BrdU-positive cells in the wounds and newborn epidermis were visible. This indicated that amniotic membrane loading epidermal stem cells accelerates epidermal migration of wound margin and wound epithelialization in diabetic rats.

Background: Vitex pinnata is a popular ethnomedicinal plant but scientific studies to validate its pharmacological properties are lacking for this plant. This study aims to determine the antioxidant, antimicrobial and wound healing properties of the methanolic extract of the leaves and the hexane, chloroform and ethyl acetate fractions.    Methods: The leaves of Vitex pinnata underwent methanol extraction and the methanol extract was fractionated with hexane, chloroform and ethyl acetate solvents. The antioxidant activity was determined using the DPPH radical scavenging assay. The antimicrobial activity was assessed by disc diffusion assay against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa. For the wound healing studies, the methanolic extracts of V. pinnata were used to prepare ointments with compositions of 10% (w/w) and 50% (w/w), which were evaluated for wound healing activity in an excision wound model in Wistar rats. Results: All the extracts showed antioxidant activities, with the ethyl acetate extract having the highest DPPH radical scavenging activity, followed by the methanol, chloroform and hexane extracts. Similarly, their quercetin equivalent concentrations were 33.1, 31, 20.3 and 4.5 mg/mL, respectively. Except for the methanol extract, the disc diffusion assay showed that the extracts demonstrated species-specific antibacterial activities, with the ethyl acetate extract showing antibacterial activities against all four tested strains. The wound healing activity of the high dose treated group (50% [w/w]) shows significant increase of wound contraction when compared to the control group. Conclusion: In the current study, the ethyl acetate extract showed activity for all tested bacteria and also had the highest DPPH activity. The methanolic extracts of V. pinnata leaves show modest wound healing activity in an excision wound model.

Delayed wound healing is producing high economic burden on the society and is generally associated with Diabetes mellitus or related complications thus needs safe treatment like herbal formulation. „Amree Plus® (an anti-diabetic ayurvedic formulation)‟ was evaluated for wound healing potential in normal and diabetic rats. The effect of polyherbal formulation Amree plus ® on wound healing has been studied in diabetic and normal animals and compared with standard (Chymoral Forte) using excision wound model. Diabetes was induced by administration of single dose of Streptozotocin 55 mg/kg i.p. The biochemical parameters i.e. hydroxyl proline content, total protein content, glutathione and superoxide dismutase (SOD) were also estimated. Rats treated with Amree Plus® at both doses i.e. 1200 and 5400 mg/kg dose per day had significantly high wound contraction both in diabetic and normal rats (88.91 & 95.05 %, respectively) in comparison to respective control. Hydroxyproline content of the granulation tissue and anti-oxidants (glutathione and SOD) level were also showing same pattern in Amree Plus® 5400 mg/kg treatment group with respect to controls. Wound contraction and other biochemical indicators results with animals Amree Plus® (1200 mg/kg) treated were found to be statistically equivalent to standard chymoral forte dose (36 kAU/kg) while Amree Plus® 5400 mg/kg dose showed statistically higher results than standard. Amree Plus®, an established antidiabetic formulation, was also showing healing of the wound in normal animals along with diabetic animals. So this finding should be confirmed further for more precision with large number of animals and small progression of doses.

Impaired skin nitric oxide production contributes to delayed wound healing in type 2 diabetes (T2D). This study aims to determine improved wound healing mechanisms by acidified nitrite (AN) in rats with T2D. Wistar rats were assigned to four subgroups: Untreated control, AN-treated control, untreated diabetes, and AN-treated diabetes. AN was applied daily from day 3 to day 28 after wounding. On days 3, 7, 14, 21, and 28, the wound levels of vascular endothelial growth factor (VEGF) were measured, and histological and stereological evaluations were performed. AN in diabetic rats increased the numerical density of basal cells (1070 ± 15.2 vs. 936.6 ± 37.5/mm3) and epidermal thickness (58.5 ± 3.5 vs. 44.3 ± 3.4 μm) (all p < 0.05); The dermis total volume and numerical density of fibroblasts at days 14, 21, and 28 were also higher (all p < 0.05). The VEGF levels were increased in the treated diabetic wounds at days 7 and 14, as was the total volume of fibrous tissue and hydroxyproline content at days 14 and 21 (all p < 0.05). AN improved diabetic wound healing by accelerating the dermis reconstruction, neovascularization, and collagen deposition.

Objective: Algae is the undisputed treasures of the sea and are a valuable raw material, providing unlimited opportunities for new drug discoveries. Marine algal products are in demand in the international market in the form of standardized algal extracts or semi-finished products. Methods: Aqueous and methanolic extracts of Oedogonium globosum and Oedogonium intermedium species were obtained maceration and hot percolation. The active principles from O. intermedium were isolated, purified by column chromatography, and characterized by spectral studies IR, λmax, 1HNMR and MS. The extracts of Oedogonium species were screened for their anti-microbial effects, acute dermal irritation and wound-healing activity studies. Results: Comparing to Oedogonium intermedium (45 %, 90 %, 87 %), very low extractive yields were obtained for Oedogonium globosum (10.80 %, 37 %, 28 %). At phytochemical screening, Terpenoids, Flavanoids and, Glycans were found to be present in a significant amount and upon their isolation, it was found that a collection of fractions from cold extract with Rf value in the range 0.32-0.34 as Glycans and those from the hot extract with 0.40-0.72 as Flavanoids and those from methanolic extracts with 0.23, 0.44 and 0.71 as for Terpenoids. Anti-bacterial study revealed out the fact of Oedogonium species could give higher inhibition to gram-positive than for gram-negative bacteria at (10 μg/10μl/disc) concentration. No symptoms of systemic toxicity and mortality were observed. Silver sulfadiazine, more potent in wound closure, the effect of methanolic extracts of O. intermedium (87 %) was almost at par to the standard (95 %) in action and significantly greater than O. globosum (72 %, P<0.05). Conclusion: Admittedly, Oedogonium type algal species can be known as medicinal algae with a plethora of a wide range of pharmacological activities. Thus, this research work may be considered further for extensive innovative discoveries of new lead molecules and any other pharmacological activities, in the future.

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.
