Introduction: Wound healing is a multifaceted biological process, and diabetic wounds add more complexity to it. In diabetic wounds, the combination of chloroform fractions of Achyranthes aspera L. (A.aspera) leaves with β-Glucans has not been investigated. The additive effect of these two (A.aspera + β-Glucans) would benefit the inflammatory phase of diabetic wounds, as improper treatment will lead to chronic injuries. Therefore, the goal of this research work was to assess the in-vivo wound healing and anti-inflammatory effects of a combination of chloroform fractions of A.aspera leaves and β-Glucans in a variety of wound models in STZ-induced diabetic rats. Methods: Preliminary phytochemical analyses of A.aspera were conducted to identify various phytoconstituents in the test extract. Acute and sub-acute dermal toxicity tests of A.aspera were carried out on mice and rats, respectively, to see whether there were any abnormalities. Excision and incision wound models, cotton pellet-induced granuloma models, rat paw edema and burn wounds were used to test wound healing and anti-inflammatory actions. To induce diabetes, streptozotocin (STZ) was administered intraperitoneally at a dosage of 65 mg/kg (i.p.). A.aspera (10% w/w) and β-Glucans (2% w/w) ointments were tested separately and in combination for wound healing activities. Silver sulfadiazine (1 % w/w) ointment was used to treat the positive control groups. Excision wound model rats that had been treated with basic ointment were used as negative controls, as were incision wound model rats that had not been treated. A.aspera (400 mg/kg, po) and β-Glucans (30 mg/kg, po) were tested separately and in combination for anti-inflammatory efficacy. Positive control groups were given indomethacin (10 mg/kg, po) for cotton pellet-induced granuloma and rat paw oedema models. Negative controls for both anti-inflammatory activity models were provided 2% Tween 80. The groups were made up of six rats, and the treatments were given topically and orally to assess wound healing and anti-inflammatory effects. The levels of hydroxyproline and hexosamine and the antioxidant enzymes (SOD and CAT) in the granulation tissue were measured in excision wound model. Healed excision wound skin was examined histopathologically. Results: The A.aspera and β-Glucans combination resulted in a significant percentage of wound contraction and a shorter epithelialization time (P<0.01). The combination was found to be the most effective, with the highest percentage of edema reduction (55 %; p<0.01). The combination also exhibited favourable hydroxylamine, hexosamine and anti-oxidant profiles supported by histopathology data. Conclusion: This research showed that the immunomodulatory effect of β-Glucans had significantly enhanced the wound healing, anti-inflammatory, and anti-oxidant potential of A.aspera in diabetic wounds.

 Objective: Wound healing is a complex process, and various plant extracts have been used to study the effect of medicinal plants on wound healing. Healol oil is used in some tribal areas for ulcer healing and treatment of burn wounds. There are no animal studies done so far using healol oil to find out its role in the treatment of wounds. Hence, the aim of our study is to find the effect of healol oil in excision as well burn wounds in Wistar rats.Methods: Thirty-six Wistar rats were used, 18 rats in excision wound model and remaining in burn wound model. Each model consists of three groups of six rats each. Povidone-iodine was used as a standard control in excision wound model and silver sulfadiazine was used as a standard control in burn wound model. Healol oil was used as test drug in both the models. Period of epithelization and wound contracture rates were analyzed. Histopathological analysis of the skin tissue was done. One-way analysis of variance was used followed by Tukey’s post hoc test for statistical analysis using SPSS version 23 software, P value of <0.05 was taken as statistical significance.Results: Both standard and test groups showed significantly faster wound healing (p<0.001) compared to control rats treated with paraffin wax in both the models. In excision model standard povidone was significantly (p<0.001) better compared to healol oil whereas in burn model, silver sulfadiazine and healol oil showed comparable results with respect to period of epithelization without statistical significance (p>0.05).Conclusion: Wound healing property of healol oil is proved, and further clinical trial can be done to find out the effect of healol oil on chronic wounds due to various etiologies.

Wound Model

There are various promising preclinical models, such as in mice, wistar rats, rabbits and pigs, which can be utilized to initiate acute or chronic wounds. These can be persuaded by many distinctive techniques, with excision the most common. After determining a proper model for a study, investigators need to choose an appropriate and reproducible technique that will permit the monitoring of the wound improvement over time. In this study, the healing power of Shark Liver Oil Emulgel (SLO) in Wistar rats were analyzed by using the excision wound model. The shark liver oil was prepared as emulgel at a concentration of 5%,10% and 15%, respectively and both Standard drug(Povidone-Iodine Ointment USP 5% w/w-PI) and SLO is applied at a concentration of 1mg/mm2; Topically. The parameters integrated for the assessment of the effects of SLO were Relative body weight changes, wound area contraction in mm2, relative wound percentage and epithelialization time. Wound area contraction was measured on 1st, 3rd, 6th, 9th, 12th, 15th, 18th and 21st day. Wistar rats treated with SLO showed substantial variations in epithelialization period and improved wound contraction in the excision wound treatment as compared to disease control. The biochemical biomarkers like SOD(Superoxide dismutases), GSH(Reduced Glutathione)and LPO(Lipid peroxidase) in the treated group have shown a significant change in the improvement of wound healing. Histopathological studies and microscopic observations specify that the topical use of Shark liver oil Emulgel extensively improved wound contraction, collagenation and epithelialization with well-organized dermis devoid of inflammatory cells in contrast to disease control.

The air-dried aerial parts of Phlomis russeliana (Sims) Lag. Ex Benth. was extracted by methanol and fractionated by n-hexane, dichloromethane, and ethyl acetate, respectively. The wound healing properties of P. russeliana extract gel was evaluated using the in vivo excisional wound model using Balb-c mice. Initially, the P. russeliana methanol extract showed LOX inhibitory activity at IC50 = 23.2 µg/mL, whereas the DPPH• assay showed IC50 = 0.89 mg/mL, and the ABTS• assay showed IC50 = 0.99 mg/mL, respectively. In addition, a remarkable anti-inflammatory activity was observed in the cell culture assay. Thereafter, activity-guided fractionation was performed by LOX enzyme inhibition assays, and the structures of the two most active fractions were revealed by both GC–FID and GC/MS analyses, simultaneously. Phytol and 1-heptadecanoic acid were characterized as the active constituents. Moreover, the P. russeliana extract gel formulation was applied for in vivo tests, where the new gel formulation supported the in vitro anti-inflammatory activity findings. As a conclusion, this experimental results support the wound healing evidence based on the ethnobotanical application of Phlomis species with further potential.
