This study was aimed to evaluate the wound healing effects of alpha mangostin ointment using excision wound model. Twenty rats were divided into four groups of five rats each; group I was treated with ointment base (control), whereas group II, group III and group IV were treated with 10% (w/w) povidone-iodine (standard), alpha mangostin 1% (w/w), and alpha mangostin 2 % (w/w) respectively for wound healing evaluations. The size of the wound area was measured, and the reduction in the wound size was calculated, and the tissues examined histologically. The significant difference in the wound size reduction between the control and treated group (p<0.05) was observed in wound healing activity. Histopathological studies showed a lesser number of chronic inflammatory cells, lesser oedema and increased collagenisation in the test than control. This study showed that the alpha mangostin topical ointment could be a promising candidate for the betterment of wound care.

Wound Healing Activity

Crassocephalum crepidioides (Benth.) S. Moore. has been used to treat small wounds by minority people in Lam Dong, Vietnam. However, there has been no scientific evidences about its wound healing activity. This study is aimed at evaluating the wound healing activity of Crassocephalum crepidioides hydroethanolic extract via its antioxidant and anti-inflammation activities and healing capability on a mouse excision wound model. Crassocephalum crepidioides hydroethanolic extract (CCLE) at a dose of 50 mg/kg/day reduced the wound closure time about 3.5 days, compared to vehicle treatment. The granulation tissue on day 7 after surgery from the treated group showed a 2.8-fold decrease in the density of inflammatory cells, 1.9-fold increase in the fibroblast density, and a higher number of blood vessels. Real-time PCR analysis indicated that the mRNA expression level of NF-κB1 and TNF-α mRNA in CCLE-treated wounds decreased by 4.6 and 3.3 times, respectively, while TGF-β1 and VEGF were found to increase by 3.3 and 2.4 times, respectively. Our experimental data provided proofs of Crassocephalum crepidioides leaf wound healing activity due to its antioxidant, anti-inflammation, fibroblast proliferation, wound contraction, and angiogenesis effects.

Background. Medicinal plants play indispensable roles to treat various ailments. Acanthus polystachyus is one of the medicinal plants used traditionally for treatment of wounds. However, there were no scientific reports documented so far on the wound healing activities of this plant. Thus, the present study provides a scientific evaluation for the wound healing potential of the crude extract of A. polystachyus leaves. Methods. The crude extraction was carried out using 80% methanol. The crude extract was prepared in 5% (w/w) and 10% (w/w) ointment and evaluated for wound healing activity using excision, infected, and incision wound models in Swiss albino mice. Results. Both 5%  and 10% (w/w) ointments significantly reduced period of epithelialization and increased wound contraction rate and tensile strength compared to the negative control group (P < 0.05). The wound healing activity of 10% (w/w) ointment treated group was greater than 5% (w/w) and nitrofurazone ointment treated groups in S. aureus infected wound model. Conclusion. These results demonstrate that the crude extract of A. polystachyus leaves possesses wound healing activities. This justifies the traditional claimed use of the plant for treating uninfected and infected wounds caused by S. aureus.

Both methotrexate and vitamin D3 are used in combination for the treatment of various diseases. The aim of this study is to highlight the effect of vitamin D3 on methotrexate-induced jejunum damage using biochemical and   histopathological  studies. Seven groups of both sexes of rats were selected and treated as follows: (Group I and Group II) : control 1,control 2 (I.P normal saline) daily for 14 and 21 days respectively ; (Group III and Group IV) :vitamin D3 groups (500 IU/rat/day) orally for 14 and 21 days, respectively;(Group V): once daily dose of methotrexate 20mg/kg, I.P injected for 4 days;(Group VI):vitamin D3 (500 IU/rat/day) once daily for 14 days and methotrexate (20 mg/kg I.P) injected only at day 10;.(Group VII) vitamin D3 (500 IU/rat/day) orally for 21 days and methotrexate (20 mg/kg I.P) injected only at day 17; then the jejunum was removed and used for measuring malondialdehyde (MDA) content, total antioxidant capacity (TAOC) level; in addition histopathological study of jejunum tissue. Administration of vitamin D3 for 21 days and a single dose of methotrexate at day 17 resulted in non-significant difference (P>0.05) in MDA; while significant reduction (P<0.05) in the TAOC level in jejunum tissue; furthermore , sever villi damage ,crypts abscess, epithelial atrophy , mixed inflammatory cells infiltrate and goblet cells depletion were observed in comparison with methotrexate group. So the study demonstrates that vitamin D3 plays a synergistic role with methotrexate therefore the combined use of vitamin D3 and methotrexate may be used as a strategy to overcome dose limitations and side effects when use for the treatment of cancer, rheumatoid arthritis and psoriasis. Key words: Jejunum damage, Methotrexate, Oxidative stress, Rats, Vitamin D3.

The present study is aimed at evaluation of phytosomal gel of the petroleum ether extract of root bark of Onosma echiodes for wound healing activity in rats. Extract of root bark of O. echioides was standardized by isolated naphthoquinone dimer using HPTLC. Phytosomes (equivalent to 2% w/w of naphthoquinones) of the standardized extract were prepared by thin film hydration technique. The wound healing efficacy of the formulation was evaluated in rats by inflicting excision and incision wounds followed by treatment of the wounds topically. The parameters evaluated for healing included determination of breaking strength and tensile strength of healed skin for incision model and percentage wound contraction, hydroxyproline content, granulation tissue free radicals and catalase in excision wound model. The formulation treated group showed a significant healing (p<0.005) of both the excision and incision wounds with respect to wound contraction and tensile strength respectively, as compared to vehicle treated group. The oxidative stress of the granulation tissue was also found to be reduced as indicated by reduced lipid peroxidation and increase in catalase activity. The phytosomal gel of O. echioides effectively exhibited wound healing effect.

Mesenchymal stromal cells and the derived conditioned media represent an area of tremendous medical interest and, among other clinical applications, are currently being extensively explored for wound healing. The aim of this study was to comparatively evaluate the wound healing potential of xeno-free human umbilical cord-derived mesenchymal stromal cells (MSCs) and the conditioned media (CM) in a full-thickness excision wound model in rats. The evaluation parameters included rate of wound healing, serum cytokine analyses, collagen content, histopathology, and hyperspectral imaging as an independent qualitative and quantitative tool. Both the cell-based and cell-free approaches scored better in lower inflammation, as evidenced in lower IL-10 and stable IL-6 levels, and improved rate of wound healing (<i>p</i> &#x3c; 0.0001). More importantly, no adverse reaction or rejection was observed although human MSCs and CM were used in a xenogeneic model. The presence of hFGF, hHGF, hGCSF, hIL-1Ra, hVEGF, and hIL-6 in the secretome may elucidate the regenerative potential of the xeno-free cell-based and cell-free approaches which have translational value for advanced wound care. The results revealed the therapeutic potential of both the cell-based and cell-free approaches for wound healing.

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.

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.

AbstractIncisional hernias and abdominal-wall defects consume large amounts of healthcare resources. Use of mesh is effective in treatment of these disorders and can decrease the rate of recurrence. This experimental study focused on the safety of mesh use in the setting of malnutrition, a condition that impairs wound healing. Rats were divided into two groups: normally fed and food-restricted. An abdominal-wall defect, 2 by 2 cm, was covered with polypropylene mesh, 2.5 by 2.5 cm. After sacrifice of the rats at the 21st and 60th days, tissue samples were sent for tensiometric and histopathological studies. No significant difference in infectious complications was observed between the two groups. Tensiometry revealed no significant differences between the groups. On histopathological examination, the only difference noted was in the vascularization scores of normally fed rats. For malnourished subjects that survived after surgery, the use of polypropylene mesh appeared safe in the closure of abdominal-wall defects, with no increase in infection rate and satisfactory wound healing.
