The aim of the study ― To investigate the effectiveness of pulsed laser with high intensity and laser with low intensity on a full-thickness wound in rats and to compare the effects of both laser types. Material and Methods ― Forty-five adult male rats were utilized in the present study. After anesthesia, wound of five cm2 was produced on dorsal aspect in each rat; then, the rats were randomly classified into three groups as follows: high power pulsating laser group (A) which received Nd: YAG laser with 1064 nm wavelength, low power laser group (B) which received GaAlAs laser with 830 nm wavelength, and control group (C) which received no treatment. Laser lights in groups (A) and (B) were introduced at an intensity of five joules per cm2 with a total energy of 25 joules for each wound area through the use of a scanning method and at a rate of 3 sessions per week for three weeks. Results ― At the end of treatment, better wound healing in form of more wound contraction and higher healing rate was elicited in both laser groups in comparison to wound healing in the control group, and there were no significantly different effects between both laser types. Conclusion ― At the intensity of five joules/cm2, both low-intensity and pulsating high-intensity lasers speed up the healing of the wound in rats, and there are no significant differences between their effects.

ABSTRACT Background: Some plants, such as betel nuts (Areca catechu), is used as traditional antiseptic. Betel nut mash is applied on ulcus wound.  Fibroblast and collagen are important factor in wound healing.  Research objective : this study is to determine the effect of betel nuts extract on fibroblast and collagen level in full thickness wound healing processs. Methodology: this study used male rats Sprague dawney that randomly divided into 3 groups. Groups I received no treatment, groups II and III received areca catechu extracts with concentration 15% and 30%  respectively. There are 12 rats in each groups. The treatment is given every day without wound’s debridement. Incision were made full thickness with diameter size 1,5 cm, on right back skin was made by lidocain anesthesia subcutaneously. Wound area were measured every days. Termination of rats were done in day 7 and day 16 to histopathology assessment with Haematoxylin-Eosin stain for fibroblast and collagen level by semiqualitative score. Results: level of collagen were higher in group that received extract but level of fibroblast were lower than control group in histopathology of day 7th. Conclusion:  Extract of betel nut increased level of collagen.

Fibroblast dan kolagen merupakan salah satu faktor penting dalam penyembuhan luka. Tujuan : Penelitian ini bertujuan mengetahui efek ekstrak biji pinang terhadap level fibroblast dan kolagen pada proses penyembuhan luka full thickness  Metode : Penelitian ini menggunakan tikus galur Sprague dawney jantan berusia 2-3 bulan dan telah mendapatkan persetujuan etik. Setelah aklimatisasi, tikus dibagi secara acak masing-masing 12 ekor dalam 3 kelompok, yaitu kelompok I tanpa perlakuan, kelompok II diberikan salep ekstrak biji pinang 15%, kelompok III diberikan salep ekstrak biji pinang 30%. Luka full thickness dibuat dengan diameter 1,5 cm di daerah punggung belakang bagian kanan dengan anestesi lidokain subkutan. Perlakuan dilakukan setiap hari tanpa debridemen luka. Luas luka diukur  setiap hari. Terminasi dilakukan pada hari ke 7 dan 16 untuk pemeriksaan histopatologi jaringan luka dengan pengecatan Haematoxylin-Eosin. Skoring secara semikualitatif untuk menilai fibroblast dan kolagen. Hasil : Pada kelompok ekstrak pinang terdapat peningkatan level kolagen, akan tetapi tidak terjadi peningkatan level fibroblast pada hasil histopatologi luka kulit hari ke-7.  Kesimpulan :  terjadi peningkatan level kolagen pada pemberian ekstrak biji pinang.

Abstract Background: Full-thickness wounds are a serious problem which badly affects patients’ life quality and also become the difficult problem for clinicians. Stem cells have great prospects in the treatment of wounds. Our previous experiments proved that autologous basal cell suspension can promote wound healing, and there are epidermal stem cells (ESCs) in basal cell suspension. We then conducted experiments to explore the effect of ESCs on full-thickness wound. Methods: In our study, the rat ESCs were isolated and expanded, and transfected with lentivirus to stably express EGFP. Experimental rats were randomly divided into 2 groups, in the ESCs group, the rat ESCs were sprayed on the Full-thickness wounds of the rats, while in control group, sprayed the PBS on the wound. Wound healing and neovascularization were then evaluated. Colonization, division and differentiation of ESCs on the wound were discovered by immunofluorescence.Results: The result suggested that rat ESCs can colonize, divide and proliferate in the wound. What’s more, the rat ESCs around blood vessels can differentiate into vascular endothelial cells and form a lumen-like structure. Compared with the control group, spraying the rat ESCs on the wound bed can promote angiogenesis and accelerate wound healing. Conclusions: Our study proved that rat ESCs were safe and effective for treating full-thickness wounds, and under certain conditions, ESCs can differentiate into vascular endothelial cells to promote angiogenesis and wound healing.

AbstractIntroduction:Laryngopharyngeal reflux is increasingly being implicated in several otolaryngological disorders.Aims:To study a potential correlation between pre-operative laryngopharyngeal reflux and wound healing and recovery after tonsillectomy, based on subjective and objective findings.Materials and methods:A prospective, blinded study was undertaken, including 60 patients scheduled for tonsillectomy, divided into two equal groups: a study group (group A) with pre-operative laryngopharyngeal reflux documented using ambulatory 24-hour pH monitoring; and a control group (group B) without laryngopharyngeal reflux.Results:Group A had significantly higher pain scores on the seventh and 14th post-operative days (p = 0.022 and p = 0.000, respectively) and took a significantly longer time to return to normal eating (p = 0.013), compared with group B. Group A also showed significantly slower healing on the seventh and 14th post-operative days, as estimated by assessing the grade of post-operative slough formation (p = 0.016 and p = 0.029, respectively). A significant correlation between the number of pharyngeal reflux episodes and the degree of post-operative slough was also found.Conclusions:Laryngopharyngeal reflux can significantly decrease wound healing following tonsillectomy. Therefore, pre-operative recognition and management of this condition is desirable in order to eliminate its negative post-operative effect.

Abstract Introduction Burn is one of the most severe traumas that causes coagulative destruction of the skin. The use of various products that accelerate wound healing in patients with burn may affect the patient’s survival and reduce the complications that may be seen. In the present study we aimed effects of subcutaneous ozone injection on second degree burn wound. Methods A total of 72 Sprague-Dawley male rats included in the study were divided randomly into three groups (control group (CG), silver sulfadiazine group (SG), ozone group (OG)) and each group was divided randomly two subgroups (as sacrificed on d7 and on d14).A deep second degree scald burns were created on the lower back. In CG subcutaneous 0.9% serum saline was injected daily into the burn area. In SG, burns were dressed with silver sulfadiazine daily and in OG subcutaneous ozone was injected daily into the burn area. Tissue hydroxyproline level measurement and histopathological evaluation were done. Results When the groups were compared in terms of weight change, no significant difference was found on the 7th and 14th days. In the evaluation made in terms of tissue hydroxyproline, tissue hydroxyproline level in OG was found to be significantly higher on both the 7th and 14th days (p < 0.001). In histopathological evaluations, it was determined that wound healing in OG was significantly higher than in the other groups. Conclusions According to the results, subcutaneous ozone therapy is more effective than silver sulphadiazine in the healing process of second-degree burn wounds and it can be safely used in the treatment of burn wounds.
