Wound Healing Activity

Abrus cantoniensis (Leguminosae sp.) is a traditionally used remedy for treating rheumatism, blood stasis, and internal injuries. In order to reveal a new insight of the utilization of the plant, solvent extraction by ethyl acetate (EA) was performed in order to evaluate the plant extracts’ in vivo excision and incision-wound potentials with models. The contents of the EA fraction, wound healing activity, acute oral toxicity, and acute dermal toxicity were studied. As a result, the main chemical constituents of the EA fraction were alkaloids, flavonoids, and steroids. The acute oral toxicity test results and assessment of skin hypoallergenicity showed that the plant extract was safe at LD50 as high as 5000 mg/kg. Both excision and incision model tests results indicated that the EA fraction of A. cantoniensis showed a significant wound healing capacity at a concentration of 5% (v/w) (p<0.01) as observed by the increased wound contraction, decreased epithelialization time, and increased hydroxyproline content compared to the ones of the controls. The present study showed that the EA fraction of A. cantoniensis possesses potential wound healing activities and provided recent results for the use of A. cantoniensis for wound curing.

Aim: This study evaluates the effect of in vivo wound healing potential of Ursolic acid rich chloroform extract of Hedyotis herbacea Linn ointment using incision and excision wound model. Study Design: Wound healing potentials of Hedyotis herbacea were analysed by Incision and excision wound model. Place of Study: Nandha College of Pharmacy, Erode, Tamilnadu. Methodology: Hedyotis herbacea was subjected to extraction (cold maceration), with solvents of increasing polarity. All the extracts were estimated for the presence of phytoconstituents by HPTLC. As the study has been focused on the phytoconstituent based biological activity, the Ursolic acid rich chloroform extract was chosen for the study of wound healing activity. The Chloroform extract of Hedyotis herbacea was incorporated into ointment base, to prepare the ointment. The ointments prepared with Chloroform extract (2.5% and 5%) of Hedyotis herbacea (CEHH) were subjected for evaluation of excision and incision wound model. Wistar albino rats were divided into four groups each consisting of six animals; group I (left untreated) considered as untreated control, group II treated with 5% w/w povidone-iodine ointment served as standard, group III treated with CEHH 2.5% w/w ointment, and group IV treated with CEHH 5% w/w ointment were considered as test groups. All the treatments were given once daily. Wound healing effect was assessed by the rate of wound contraction, level of total protein, Hydroxy proline, Hexosamine and Hexuronic acid and histopathology studies in an excision wound model. Tensile strength was also measured in both excision and incision wound. Results: Wound healing activity of CEHH 5% w/w ointment treated group was greater than CEHH 2.5% w/w and untreated groups in both excision and incision wound model. The high rate of wound contraction (*P< 0.001), high tensile strength (*P< 0.001), and elevated total protein, Hydroxyproline, Hexosamine, and Hexuronic acid content were observed in animals treated with CEHH ointments when compared to the untreated control group of animals. Histopathological studies of the CEHH ointments treated groups also revealed the effectiveness in wound healing. Conclusion: These results justified the claimed traditional use of the Hedyotis herbacea as wound healing plant.

Wound Healing Activity

Spirulina is a microalga used in traditional folk medicine in Morocco for the treatment of various health disorders. The wound healing activity of Moroccan Spirulina is unknown. In the current study, aqueous extracts of Spirulina platensis were investigated for acute toxicity and wound healing activity in Swiss Albino mice and White New Zealand rabbits, respectively. The LD50 (amount of substance required to kill 50% of the test population) of the microalga was greater than 5,000 mg/kg. Healing after application of the same amount of ointment on differently induced (mechanical, chemical, and thermal) wounds was about the same, over five weeks. Aqueous extract had remarkable healing activity on rabbits’ skin, possessing significantly greater healing effect for mechanical and chemical burns than controls. Moreover, the hair growing time was faster in treated groups; Spirulina-treated groups did not show any contamination with microbes compared to others. This study affirms that Spirulina platensis can be considered as a potential therapeutic agent for wound healing not only as a complementary medicine but also in conventional medicine.

By activating PPAR-γ, thiazolidinediones normalize glucose levels in animal models of type 2 diabetes and in patients with this pathology. The aim of the present study was to analyze 219 new derivatives in silico and select the best for synthesis, to be evaluated for acute oral toxicity in female rats and for control of diabetes-related parameters in a rat model of streptozotocin-induced diabetes. The best compound was chosen based on pharmacokinetic, pharmacodynamic, and toxicological parameters obtained in silico and binding orientation observed by docking simulations on PPAR-γ. Compound 1G was synthesized by a quick and easy Knoevenagel condensation. Acute oral toxicity was found at a dose greater than 2000 mg/Kg. Compound 1G apparently produces therapeutic effects similar to those of pioglitazone, decreasing glycaemia and triglyceride levels in diabetic animals, without liver damage. Moreover, it did not cause a significant weight gain and tended to reduce polydipsia and polyphagia, while diminishing systemic inflammation related to TNF-α and IL-6. It lowered the level of endogenous antioxidant molecules such as reduced glutathione and glutathione reductase. In conclusion, 1G may be a candidate for further testing as an euglycemic agent capable of preventing the complications of diabetes.

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: 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.
