Platelet-rich plasma (PRP) has been extensively studied as a biomaterial for wound treatment, and the heterologous PRP is usefulin the event that obtaining the patient’s own blood is impossible. This study aimed to evaluate and compare wound healing in rabbits and quantify the collagen in experimentally induced wounds in a control group and in a group treated with heterologous PRP gel. We hypothesize that this gelis capable of promoting proper healing with no adverse reactions, increased collagen content. The clinical aspects of coloring, edema, hyperemia, exudation, crust, granulation, pain sensitivity, and retraction index of the wounds were measuredon days 7, 14, and 17 after the injury. Collagen quantification by Picrosirius staining and evaluation under polarized light was performed on the 17th day. Crust was present in both groups at all evaluated time points, with the absence of other clinical signs. The wound contraction rate and collagen quantity did not differ between groups. In conclusion, the suggested hypothesis was partially confirmed; the heterologous PRP gel was unable to increase the amount of collagen and accelerate the wound healing process, however, wound healing was efficient and similar in both groups and there was no local adverse reaction. Thus, despite the scarcity of studies in the literature, the heterologous PRP gel is an effective alternative treatment for wounds in the absence of other sources of PRP.

Introduction. The healing process of tooth extraction is desired to take place faster to restore the normal tissue. Physical exercise is proven to accelerate wound healing through various physiological mechanisms. Aerobic exercise increases oxygen perfusion which leads to wound healing process. On the other hand, anaerobic exercise stimulates reactive oxygen species and may interfere with the wound healing process. Objective. To observe if there are differences in the effectiveness of wound healing after tooth extraction based on the number of fibroblast and neovascularization in Wistar rats (Rattus norvegicus) that performed interval aerobic or anaerobic exercise. Methods. Rats were divided into 3 groups, a control group and two treatment groups which performed the aerobic physical exercise or the anaerobic physical exercise. Fibroblast and neovascularization were calculated 7 days after the tooth extraction. Data were analyzed using Krusskal-Wallis statistical tests. Results. The aerobic exercise group showed the higher number of fibroblasts and neovascularization compared to anaerobic exercise group, while the control group showed the lowest number of fibroblast and neovascularization. Conclusion. This study demonstrated that aerobic physical exercise accelerates wound healing in the proliferation phase better than anaerobic exercise and no exercise.

<p>Two oil blends (sunflower/canola oils 85/15 (BL1) and canola/linseed oils 70/30 (BL2)), were prepared and enzymatically interesterified to be applied to surgically-induced wounds in rats. Following surgery, the animals were submitted to the Treatment with Physiological Saline (TPS) (control group), Blends (TBL), and Structured Lipids (TSL). The control group (TPS) received physiological saline solution for 15 days. In TBL, BL1 was administered during the inflammation phase (days 0-3) and BL2 in the tissue formation and remodeling phase (days 4-15). In TSL, Structured Lipid 1 (SL1) and Structured Lipid 2 (SL2) were used instead of BL1 and BL2, respectively. The aim of this study was to compare wound closure evolution among rats treated with the blends or structured lipids versus control rats treated with physiological saline. The wound healing process was evaluated by measuring the wound areas along the treatments and the concentrations of cytokines. An increase in the areas of wounds treated with the blends and structured lipids in the inflammatory phase was observed, followed by a steeper closure curve compared to wounds treated with physiological saline. The changes observed during the inflammatory phase suggest a potential therapeutic application in cutaneous wound healing which should be further investigated.</p>

Abstract: Diabetic foot ulcer (DFU) is still a health problem related to the extent amount of time in wound healing process hence increasing the treatment cost. Given any methods that are not sat-isfying, encourage the search of other methods that would increase the wound healing rate, in which hyperbaric oxygen therapy (HBOT) is amongst them. The DFU patient that receives HBOT shows a significant increase in angiogenesis process markedly by faster epithelialization and granulation process. This study was aimed to prove that HBOT could accelerate the wound healing process among DFU patients measured by wound size and depth of PEDIS score. This was a ran-domized controlled trial study, conducted at Surgery Department of Prof. Dr. R. D. Kandou Gen-eral Hospital from September 2018 to March 2019. There were 20 DFU patients divided into two groups, each of 10 patients. The control group received a holistic treatment, meanwhile the HBOT group received a holistic treatment added with the inclusion of HBOT. PEDIS score assessment of DFU in HBOT group was measured before and after the third HBOT session, meanwhile the con-trol group was measured on the first and the third day. The results showed that the difference in PEDIS score value was markedly found in HBOT group compared to the control group (2 vs. 0, P=0.001). Conclusion: HBOT could enhance the wound healing process in DFU patients based on the declined PEDIS score.Keywords: HBOT, PEDIS score, diabetic foot ulcerAbstrak: Ulkus kaki diabetik (UKD) masih merupakan masalah kesehatan terkait proses penyembuhan lama sehingga biaya pengobatan meningkat.

The wound healing process of the soft tissue aims to accelerate the closing of the wound by recurring, restoring the function, and minimizing the scar tissue. This process has to occur in the surgery process to obtain better-wound healing. The aim of this study was to know the stimulation effect of the wound dressing to accelerate the wound healing process of the soft tissue using Collagen (amino acid) and Amnion (proteinase inhibitors). This true experimental study was done to 36 mice (Sprague Dawley) that were divided into three different groups, two groups were the treatment groups and one group was the control group. Each group was adapted in Pathology Laboratory of Faculty of Veterinary Medicine Bogor Agricultural University. All of the mice were injured on the skin by incising the right side of the back for 2 cm in length and 4 mm in depth and then cleaned with 0.9% NaCl solution. To the first group of treatment, the wound was applicated by Amnion, and the second group was applicated by Collagen. Each 4 mice of all group were a termination by ether and encryption on the wounded tissue was conducted on day 3rd, 7th, and 14th. Assessment for a number of fibroblast and collagen synthesis on the wound of back tissue was conducted with the histological examination by painted using hematoxylin-eosin. The results concluded that Collagen application was influencing the mean of fibroblast higher than Amnion, and the lowest was controlled with statistically significant. The mean of collagen used Collagen lower than Amnion, and the lowest was control with statistically significant. It could be concluded that collagen application was preeminent in increasing the productivity of the fibroblast, as well as in developing forms of the collagen synthesis compared with Amnion and control.

. Background: Wound healing of the nasal mucosa after endoscopic sinus surgery (ESS) is frequently complicated by scaring and consequently recurrences are encountered. Methods of optimizing results have been sought. In the present study we evaluated the effects of a powerful antioxidant, astaxanthin, on nasal mucosa healing after surgery, comparing it to the extensively studied properties of dexamethasone. Materials and Methods: 63 Wistar rats were used. The nasal mucosa from one side was damaged employing the brushing method. They were randomly divided into three experimental groups, one treated with astaxanthin, the second treated with dexamethasone and the third one acted as the control and was given normal saline. The rats were killed on days 5, 14 and 28 following injury. We observed the temporal evolution of the wound healing process and quantified the results by assessing four parameters: the epithelial thickness index (ETI), the subepithelial thickness index (STI), the goblet cell count and the subepithelial fibrosis index (SFI). Results: At 28 days, the ETI was significantly lower in the astaxanthin group (p < 0.05) compared to the other two groups. The STI was also lower in the astaxanthin group (p < 0.05), but comparable to the dexamethasone group at 28 days. The goblet cell count was higher in the astaxanthin group. The SFI had similar results in both dexamethasone and astaxanthin groups, with lower values compared to the control group. In the astaxanthin group there was no synechia formation. Conclusion: Astaxanthin given in the post injury period significantly decreases fibrosis, inhibits synechia development and significantly decreases subepithelial fibrosis. Moreover, it has no general or local toxic effects.
