Aim: Lawsonia inermis (LI), a naturally grown or cultivated shrub in Northeast of Africa and India, has been traditionally used as a strong remedy for several injuries. However, few studies have reported its use as a cicatrizing agent. The aim of this study was to evaluate the effect of daily application of an ointment prepared with LI leaves' powder on wound healing in Wistar rats. Materials and Methods: Twenty female Wistar rats were used in this study. Excisional wound model was realized by removing skin from the dorsal part of the neck of each animal. Wounds have been then treated by a daily application of LI ointment prepared by mixing leaves' powder to petroleum jelly in test group and by simple application of petroleum jelly in control group. Evaluation of wound healing activity was then based on calculating the percentage of wound contraction, period of epithelialization, and wound index every 3 days for a period of 24 days, then, a histological study of the healed excised wound was performed. Results: Treatment with LI has shown excellent wound healing activity, since it has increased percent of wound contraction, and reduced period of epithelialization and wound index as compared to control (p<0.05). These results have been supported by the histological findings that revealed better epithelialization, dermal differentiation, collagen fiber orientation, and angiogenesis in LI treated rats compared to control (p<0.05). Conclusion: We can conclude that LI leaves' can be used as a potential wound healing agent.

Phytochemical, antioxidant and antimicrobial activities of the seeds of Chrysophyllum albidum have been established. However, scientific evaluation of its wound healing activity is lacking. Thus, this study was aimed at evaluating the wound healing potential of Chrysophyllum albidum hexane seed extract using wistar rats. The seed cotyledon was collected, air-dried, blended and extracted with n-hexane by continuous cold extraction. Phytochemicals, antioxidant and antimicrobial activities of the extracts were assayed by standard methods. Three groups of male wistar rats consisting of seven animals each were used for the animal studies. Wound excision was induced on all animals in the sterilized shaved dorsal fur region.Group1 served as the negative control (untreated), groups 2 and 3 were treated with n-hexane extract (test group) and Povidone-iodine ointment (positive control) respectively. Wound contraction rate and epithelialization time were used to assess the efficiency of the treatment. Group 3 rats had best wound contraction rate with epithelialization time of 16 post-wounding day followed by group 2 (20 days) and group 1 (28 days). The wound healing efficiency of the extract was less than that of the standard ointment but it healed the wound inflicted on the rats faster than the untreated ones. The low wound activity of the seed extract may be due to low phytochemical, antioxidant and antimicrobial activity of the extract. Chrysophyllum albidum hexane seed extract have some wound healing activity and therefore have potential for being used as wound healing ointment.

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 leaves ofCarapa guianensishave been used to treat ulcers, skin parasites, and skin problems. The ethanolic extract ofC. guianensisleaf was evaluated for its antibacterial and wound healing activity using excision, incision and dead space wound models in rats. The animals were randomly divided into two groups (n= 6) in all the models. In the excision wound model test group animals were treated topically with the leaf extract (250 mg kg−1body weight) whereas, control animals were treated with petroleum jelly. In the incision and dead space wound models, the test group animals were treated with extract (250 mg kg−1day−1) orally by mixing in drinking water and the control group animals were maintained with plain drinking water. Healing was assessed by the rate of wound contraction, period of epithelialization, skin breaking strength, granulation tissue weight and hydoxyproline content. On Day 15 extract-treated animals exhibited 100% reduction in the wound area when compared to controls (95%) with significant decrease in the epithelialization period. The extract failed to demonstrate antibacterial activity. Skin breaking strength (P< .001), wet (P< .002) and dry (P< .02) granulation tissue and hydroxyproline content (P< .03) were significantly higher in extract treated animals. The increased rate of wound contraction, skin breaking strength and hydroxyproline content supports potential application ofC. guianensisin wound healing.

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.

Objective: One of the sequelae of diabetes mellitus is chronic foot ulcer. This study investigated wound healing propensity of the pulp and rind of Ananas comosus (a widely cultivated fruit with many health benefits) in diabetic wistar rats. Methods: The excisional wounds of twenty four adult wistar rats with induced diabetes in four groups of six each were dressed with the pulp powder (PPD), pulp extract (PED), rind powder (RPD) and rind extract (RED) of A. comosus daily till healed. Also the mean wound contraction rates were calculated from the wound areas every three days. Granulation tissue was biopsied from an animal per group on day 3, 6 and 9 for histopathological evaluation. Each of these groups had a corresponding equal number control group with similar procedures performed. Results: The mean wound contraction rates of the rind pulp diabetic (RPD) and rind extract diabetic (RED) groups paralleled those of their respective control group (RPC, REC) as they were not significantly different. Also amongst the diabetic groups, the rind of A. comosus demonstrated greater wound healing capability over the respective pulp counterpart (PPD, PED) as evidenced by significantly higher mean wound contraction rates. Histopathologic features of the granulation tissues and scars of the diabetic groups were similar to those of the control groups. Conclusion: Although, both the rind and pulp of unripe A. comosus either in extract or powder formulation were shown in this study to possess excellent healing potentials in diabetic wounds, the rind appeared to be better off and may be a viable alternative to the wound dressing materials currently in use in the management of diabetic wounds / ulcers.

Introduction and Aim: Wound healing is an integrated process of cellular and biochemical events in restoring the structural functionality of the damaged tissue caused due to wounds. In the present study, the wound healing potential of an ayurvedic polyherbal formulation, Amrit oil is tested on an experimental model of the excisional wound in Wistar rats and evaluated for its potent activity in wound repair. Materials and Methods: Wistar rats were randomly arranged into 4 groups with 6 in each. Excision wound was created on the dorsal side of the rats. Group-I was kept as a negative control, Group-II as reference control, treated with Betadine, Group-III received a tropical application of Amrit oil once in a day and Group- IV were subjected to tropical application of amrit oil twice or Bis in a day. The wound healing was assessed by percentage wound contraction, a period of epithelisation, histopathological analysis and expression of MMP- 2, MMP-8, KGF and HSP-90. Results: The effect produced by the ayurvedic polyherbal formulation (Amrit oil), in terms of percentage wound contraction, a period of epithelisation, biochemical gene expression (MMP2, MMP8, HSP90 and KGF) and histopathological analysis were comparable to that of standard drug betadine. This study reveals the healing potential of Amrit oil as compared to the positive control, betadine possibly due to the presence of the phytochemicals in a synergistic manner. Conclusion: This study revealed a tremendous healing potential of Amrit oil as compared to the positive control, betadine in a holistic manner, confirming the rationality of the traditional knowledge.

Rhodomyrtus Tomentosa

Background: The process of wound healing is influenced by various factors such as age, hormones, and wound care. Wound care is done to accelerate wound healing which can be done by various methods, one of them is traditional care. Traditional wound care can use medicinal plants. Rhodomyrtus tomentosa is a medicinal plant that has an antioxidant, anti-inflammatory, antitumor and antibacterial content. Thus this study aims to evaluate the effectiveness of the antiseptic solution of the Rodhomyrtus tomentosa leaf extract on wound healing in male Wistar rats. Method: this research is pure experimental research with post test only control group design. Thirty male white rats were divided into five groups, namely negative control, positive control, Rhodomyrtus tomentosa leaf extract 15%, 30%, and 60%. Rhodomyrtus tomentosa leaf extraction was carried out by maceration method with 70% ethano solvent. The extraction results are divided into 3 concentrations (15%, 30% and 60%). The wound healing process was evaluated by measuring the length of the wound manually from 0 to 10 days in each group. Meanwhile, the number of fibroblast cells was calculated through hematoxylin eosin (HE) staining and observed using an Olympus CX41 microscope with a 10x magnification and objective lens magnification in 3 fields. Result: There was a significant difference in the reduction in wound length (p =< 0,000) between the five experimental groups (Rhodomyrtus tomentosa leaf extract solution 15%, 30% and 60%, negative control and positive control. Solution of rhodomyrtus tomentosa leaf extract accelerated the increase in the number of fibroblasts compared to the negative control group (p = 0.003), but did not make a difference (p = 0.403) with the positive control group. Rhodomyrtus tomentosa leaf extraction solution had the same microscopic effect on the number of fibroblasts with a positive control group given 0.9% NaCl solution. Conclusion: There was a significant difference in the number of fibroblasts between all groups, but no difference in wound healing length.

Highly active antiretroviral therapy (HAART) is considered toxic and has other life-threatening side effects. Our aim was to evaluate the haematotoxic effects of lamivudine, zidovudine, and nevirapine fixed-dose combinations in Albino Wistar rats. Fifty (50) three (3) months old male Albino Wistar rats weighing between 200 and 250 g were randomly assigned to five (5) groups (A, B, C, D, and E). Group A served as control. Two (2 mLs) of venous blood was aseptically collected on Days 5, 10, 15, 20, and 25 of treatment. Red blood cell (RBC) mean value recorded statistically significant increase () in groups B and C when compared with the control group on Day 5. However, there was a statistically significant decrease () in RBC, haemoglobin concentration (Hb), packed cell volume (PCV), and some red cell indices on Day 10. In addition there was no statistically significant difference () in all the parameters evaluated when the test group was compared with the control on Day 25. Furthermore, there was a time-related statistically significant increase () in the two major blood cells—RBC and platelet counts. From the result of this present study, it can be concluded that HAART when administered in fixed-dose combinations have no subacute haematotoxic effects.
