Aloe vera is a medicinal plant used to treat various skin diseases. The effects of using aloe vera gel on the healing process were investigated by microscopic methods, cell counting, and TGF-β gene expression in the wound bed. Sixty Wistar rats weighing 200–250 g were placed under anesthesia in sterile conditions. A square 1.5 cm × 1.5 cm wound was made on the back of the neck. The rats were divided into control and 2 experimental groups. Additionally, the control and experimental groups were separated into 3 subgroups corresponding to 4, 7, and 14 days of study. In the first experimental group, aloe vera was used twice on the wound. The second experimental group received aloe vera overtreatment once on the wound. The positive control group received daily application of 1% phenytoein cream following surgical wound creation. The control group did not receive any treatment. This tissue was examined using histological staining (H&E) and Masson’s Trichrome. Wound surface and wound healing were evaluated separately. TGF-β gene expression was analyzed by RT–PCR. Results showed that fibroblasts in both experimental groups were significantly increased, thereby acceleration wound healing. Application of aloe vera gel will increase TGF-β gene expression, ultimately accelerating the wound healing process.

Background: Research has proved that Aloe vera has anti-inflammatory, anti-bacterial, and immunomodulator properties that can accelerate the healing process. These properties could be beneficial in the tooth extraction wound-healing process. Neutrophils are the first inflammatory cells to invade and are the predominant cell markers in the wound for 24 hours after injury. Polymorphonuclear leukocytes (PMN) provide initial protection against micro-organisms, as they engulf and digest foreign bodies. Purpose: The aim of this study was to prove the effect of Aloe vera 90% gel application on the PMN count in the healing process of Cavia cobaya following tooth extraction. Methods: This laboratory experimental research was done using Post-Test Only Control Group Design. The lower incisive of twelve male Cavia cobayas were extracted then divided into four groups. Group P1 and P3 had 90% Aloe vera gel applied into the socket and sutured; group K1 and K3, received no 90% Aloe vera gel application and acted as controls. Samples from group P1 and K1 were terminated and had their mandibula taken one day after tooth extraction, and those from group P3 and K3 were terminated after three days. Tissues were then processed into histology slides, and PMN cells were counted. Results: There were significant differences in the PMN count between groups K1, P1, and K3 compared with P3 (p < 0.05). Higher PMN count was shown on the group containing Aloe vera 90% gel compared with control group, both on day one and three after tooth extraction. Conclusion: Aloe vera 90% gel can increase the PMN count in the inflammation phase of the tooth extraction wound-healing process.

Background The present study aimed to prepare effective silk derived formulations in combination with plant extract (Aloe vera gel) to speed up the wound healing process in diabetic mice. Methods Diabetes was induced in albino mice by using alloxan monohydrate. After successful induction of diabetes in mice, excision wounds were created via biopsy puncture (6 mm). Wound healing effect of silk sericin (5%) and silk fibroin (5%) individually and in combination with 5% Aloe vera gel was evaluated by determining the percent wound contraction, healing time and histological analysis. Results The results indicated that the best biocompatible silk combination was of 5% silk fibroin and 5% Aloe vera gel in which wounds were healed in 13 days with wound contraction: 98.33 ± 0.80%. In contrast, the wound of the control group (polyfax) healed in 19 day shaving 98.5 ± 0.67% contraction. Histological analysis revealed that the wounds which were treated with silk formulations exhibited an increased growth of blood vessels, collagen fibers, and much reduced inflammation. Conclusion It can be concluded that a combination of Bombyx mori silk and Aloe vera gel is a natural biomaterial that can be utilized in wound dressings and to prepare more innovative silk based formulations for speedy recovery of chronic wounds.

Abstract Background Collagen is the most abundant structural protein in the mammalian connective tissue and represents approximately 30% of animal protein. The current study evaluated the potential capacity of collagen extract derived from Nile tilapia skin in improving the cutaneous wound healing in rats and investigated the underlying possible mechanisms. A rat model was used, and the experimental design included a control group (CG) and the tilapia collagen treated group (TCG). Full-thickness wounds were conducted on the back of all the rats under general anesthesia, then the tilapia collagen extract was applied topically on the wound area of TCG. Wound areas of the two experimental groups were measured on days 0, 3, 6, 9, 12, and 15 post-wounding. The stages of the wound granulation tissues were detected by histopathologic examination and the expression of vascular endothelial growth factor (VEGF), and transforming growth factor (TGF-ß1) were investigated using immunohistochemistry. Moreover, relative gene expression analysis of transforming growth factor-beta (TGF-ß1), basic fibroblast growth factor (bFGF), and alpha-smooth muscle actin (α-SMA) were quantified by real-time qPCR. Results The histopathological assessment showed noticeable signs of skin healing in TCG compared to CG. Immunohistochemistry results revealed remarkable enhancement in the expression levels of VEGF and TGF-β1 in TCG. Furthermore, TCG exhibited marked upregulation in the VEGF, bFGF, and α-SMA genes expression. These findings suggested that the topical application of Nile tilapia collagen extract can promote the cutaneous wound healing process in rats, which could be attributed to its stimulating effect on recruiting and activating macrophages to produce chemotactic growth factors, fibroblast proliferation, and angiogenesis. Conclusions The collagen extract could, therefore, be a potential biomaterial for cutaneous wound healing therapeutics.

Background: In the present research study, the rate of cutaneous wound healing and contraction rate in healthy rabbits using Aloe vera pulp was studied.Methods: Ten healthy rabbits were used for the study. They were divided into two groups consisting of five rabbits each. Cutaneous wounds were made on the lumbar region of each rabbit using a template which ensured that the wounds were of the same size in all the rabbits. 5ml of Aloe vera gel was applied to the wounds of the animals in the test group, while nothing was applied to the wound area of the animals in the control group. The wound area in each group was measured for a period of 21 days, using a venire caliper and tracing paper which was used to trace the wound area. Tissue samples were removed from the wound area in both experimental and control groups and subjected to routine histological analysis, also, morphometric analysis was performed.Results: The rate of wound contraction and mean centripetal contraction was calculated in both groups and graphically represented using Microsoft Excel. The results showed that animals who were treated with Aloe vera gel had a greater wound contraction rate, as well as rapid wound closure. The micrographs showed a thicker epithelial layer, with thinner collagen fibers in the dermis of experimental animals compared to the control group. There was also an abundant capillary bed at the dermal-epidermal junction in the experimental group, compared to the control group.Conclusion:  Aloe vera may increase the rate of wound healing by accelerating epithelial migration, and may also play a role in neo-vascularization of the newly healed area.Keywords: Aloe vera, Cutaneous Wounds, Rabbits, Wound Contraction, Wound Healing

Abstract Background Prolonged and overlapping phases of wound healing in diabetes are mainly due to the redox imbalance resulting in the chronicity of the wound. Photobiomodulation therapy works on the principle of absorption of photon energy and its transduction into a biological response in the living tissue. It alleviates the cellular responses, thereby improving the mechanism of wound healing in diabetes. Objective To find out the effect of photobiomodulation therapy of dosage 4 J/cm2 in the healing dynamics of diabetic neuropathic wounds in Wistar rats and its relation with oxidative stress markers. Methodology Diabetes was induced using Streptozotocin of 60 mg/kg of body weight to eighteen female Wistar rats. Neuropathy was induced by the sciatic nerve crush injury followed by an excisional wound of 2 cm2 on the back of the animal. Experimental group animals were treated with dosage 4 J/cm2 of wavelength 655 and 808 nm, and control group animals were kept unirradiated. The biomechanical, histopathological, and biochemical changes were analysed in both groups. Results There was a reduction in mean wound healing time and an increased rate of wound contraction in the experimental group animals compared to its control group. The experimental group showed improved redox status, and histopathological findings revealed better proliferative cells, keratinisation, and epithelialization than un-irradiated controls. Conclusions Photobiomodulation therapy of dosage 4 J/cm2 enhanced the overall wound healing dynamics of the diabetes-induced neuropathic wound and optimised the oxidative status of the wound, thereby facilitating a faster healing process.
