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.

The term “wound” is defined as a disruption of normal anatomical structure. Therefore, “healing” is the complex and dynamic process that results in the restoration of anatomical continuity and function. Albino Wistar rats (150-180 g) of both sexes were selected. The experiment of Wound Healing Activity by Excision Wound Model and Incision Wound Model by the simple ointment B.P., reference standard drug (0.2% w/w nitrofurazone ointment), stigmasterol ointment (0.2% w/w), hexane, chloroform and methanol extract ointments of 3%, 4% and 5% w/w of leaves in Jatropha tanjorensis in simple ointment base (where 3g, 4g and 5 g of the extracts was incorporated in 100 g of simple ointment separately). The time for wound closure to methanol extract ointment (5% w/w) and stigmasterol (0.2% w/w) was similar to that of standard drug, nitrofurazone ointment (0.2% w/w) 16 ± 2 days in Excision Wound Model. The significant tensile strength at 3%: 4%: 5% w/w methanol extract ointments (p<0.001), followed by chloroform extract and hexane extract. Stigmasterol ointment at 0.2% w/w produced tensile strength comparable with Standard drug, nitrofurazone ointment (0.2% w/w) (p<0.001) in Incision Wound Model.  Kirithikar and basu stated that the juice of the Jatropha plant and the pounded leaves are applied to wounds and refractory ulcers. The juice is very successfully used to treat scabies, eczema and ringworm. The present study proved that the leaves have wound healing activity.

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.

BACKGROUND -This study undertaken to screen a potential wound healing activity of an ethanolic extract of Anacardiumoccidentale(Ao)leaves in Wistar rats. MATERIALS AND METHODS-Excision wound of 500mm2created on the back of Wistar rats. A total of thirty adult Wistar rats were prescreened and divided into five groups of six rats each.Group I and II rats were treated by normal saline (control) and povidone-iodine (standard drug), respectively. Group III and IV with 0.5% and 2%of Anacardiumoccidentale ointment (test drugs), respectively, and Group V rats treated with anti-wound healer drug dexamethasone, i.m. + 2% Anacardiumoccidentale. All drugs were applied topically except Inj. dexamethasone. In the model of excision wound, the wound healing effect was determined by parameters such as the percentage of wound contraction, duration of epithelialization, and histopathological examination. RESULT-All drugs, povidone-iodine, 0.5%, and 2% of the Ao ointment treated group of rats showed a statistically significant increase (P<0.05) in the % of wound contraction on 5th and 6thdays Vs.Control rats. In contrast,povidone-iodine, 2% Ao ointment and (dexamethasone + 2% Ao)treated rats decreased the period of epithelialization which was statistically significant (P<0.05) compared to the control.However, the standard povidone-iodine treated rats showed a maximum increase in the percentage of wound contraction and minimum period of epithelialization, followed by a higher dose of 2% Ao extract. The plant extract 0.5% and 2% of Ao showeda significant increase inthe rate of wound contraction as compared to the standard drug povidone-iodine also. The combination of (2%Aoextract+dexamethasone) drug-treated rats decreased the rate of wound contraction on 5th, 9th days; whereas, povidone-iodine increased on all days, i.e., 5th, 9th, 13th and 17th days,which was statistically significant (p<0.05) Vs.Normal saline. The povidone and 2% of Ao extract hastened the rate of wound healing activity, which was evident by maximum re-epithelialization and presence of the collagen fibers. CONCLUSION-In our study, the topical application of Anacardiumoccidentale leaf extract has shown promising wound healing activity; however, it failed to reverse the anti-wound healing property of steroids.

The fruiting branches ofColutea cilicicaBoiss. & Bal., along with leaves and fruits, have been used to heal inflammatory wounds at traditional medicine in various parts of Turkey. In order to evaluate the wound healing activity of the plant, aqueous extracts were prepared from the flowering parts and fruits ofColutea cilicicaBoiss. & Bal. by using 40°C distilled water. Incision wound healing models by using tensiometer on rats and excision wound healing models on mice were employed to assess the activity. Significant wound healing activity was observed when ointment formulation of the aqueous extract at 1% concentration was applied on the mentioned models. The fruit extract treated the groups of animals, showing a 78.1% contraction in wounds, which was close to the contraction value of the reference drug Madecassol (100%). On the other hand, the same extract used on the incision wound model demonstrated a significant increase (42%) in wound tensile strength, compared to the flowering aerial parts. Histopathological examination also supported the results shown in both the incision and excision wound models. The wound healing effect was evaluated and compared with the reference ointment Madecassol. Moreover, zinc and vitamin C levels in the fruit (9480 ± 0 mcg g−1; 389 mg g−1) and flowering aerial part (6609 ± 1 mcg g−1; 404 mg g−1) extracts, which might have contributed to the wound healing process, were determined. The experimental data confirmed the traditional usage ofC. cilicicaBoiss.& Bal.
