Although many previous studies reported that honey promotes wound healing, no study has examined the effects of Japanese honey. The aim of this study was to investigate the effects of three types of Japanese honey, Acacia, Buckwheat flour, and Chinese milk vetch honey, on wound healing in comparison with hydrocolloid dressing. Circular full-thickness skin wounds were produced on male mice. Japanese honey or hydrocolloid dressing was applied daily to the mice for 14 days. The ratio of wound area for the hydrocolloid dressing group increased initially in the inflammatory and early proliferative phases and then decreased rapidly to heal with scarring. However, the ratios of wound area for the Japanese honey groups decreased in the inflammatory phase, increased in the proliferative phase, and decreased in the proliferative phase, and some wounds were not completely covered with new epithelium. These findings indicate that using Japanese honey alone has limited benefit, but since it reduces wound size in the inflammatory phase, it is possible to apply a combined treatment in which Japanese honey is applied only in the inflammatory phase, followed by hydrocolloid dressing from the proliferative phase, which would effectively contract the wound.

The purpose of this study is to evaluate and clarify the effect of Indonesian honey, two types of Japanese honey and hydrocolloid dressing on wound healing process. Four groups of male mice were treated to produce two circular full-thickness skin wounds on the dorsum. They were then randomly allocated to receive daily Indonesian honey, Japanese honey (Buckwheat and Acacia honey) or hydrocolloid dressing as a control for treatment application. Macroscopic findings were observed from day 0 to 14 after wounding. Microscopic evaluation was assessed using qualitative analysis. The ratios of wound areas for honey groups on day 3 and 7 were smaller than those of the control group. Wound areas of honey groups gradually decreased to almost the same wound area as the control group on day 14, while the wound area of the control group peaked on day 5 and rapidly decreased until day 14. Microscopic finding that Indonesian honey was different with Japanese honey especially Buckwheat honey.

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. Keyword : areca catechu, betel nuts, wound, fibroblast, collagen, histopathology   ABSTRAK Latar belakang :  Beberapa tanaman digunakan sebagai antiseptik luka, salah satunya biji pinang  untuk penyembuhan luka ulkus. 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. Kata kunci : biji pinang, luka, histopatologi, fibroblast, kolagen

Wounds with full-thickness skin loss are commonly managed by skin grafting. In the absence of a graft, reepithelialization is imperfect and leads to increased scar formation. Biomaterials can alter wound healing so that it produces more regenerative tissue and fewer scars. This current study use the new chitosan based biomaterial in full-thickness wound with impaired healing on rat model. Wounds were evaluated after being treated with a chitosan dermal substitute, a chitosan skin substitute, or duoderm CGF. Wounds treated with the chitosan skin substitute showed the most re-epithelialization (33.2 ± 2.8%), longest epithelial tongue (1.62 ± 0.13 mm), and shortest migratory tongue distance (7.11 ± 0.25 mm). The scar size of wounds treated with the chitosan dermal substitute (0.13 ± 0.02 cm) and chitosan skin substitute (0.16 ± 0.05 cm) were significantly decreased (P<0.05) compared with duoderm (0.45 ± 0.11 cm). Human leukocyte antigen (HLA) expression on days 7, 14, and 21 revealed the presence of human hair follicle stem cells and fibroblasts that were incorporated into and surviving in the irradiated wound. We have proven that a chitosan dermal substitute and chitosan skin substitute are suitable for wound healing in full-thickness wounds that are impaired due to radiation.

Purpose In this study, we aimed to determine the regenerative and antimicrobial impact of the electrospun nanofiber mats, with/without silver nanoparticles (AgNPs), on full-thickness skin wounds in rabbits. Methods Polyvinyl alcohol was combined with gelatin to provide biocompatible electrospun binary nanofiber mats. AgNPs were added to the polyvinyl alcohol/gelatin mixture to obtain ternary nanofiber-AgNPs mats. Binary and ternary nanofiber mats were characterized by scanning electron microscopy before being applied as wound dressings in vivo. Subsequently, wound healing was evaluated. Results Both nanofiber/nanofiber-AgNPs mats improved the microscopic quality of the healed skin, albeit without obvious acceleration of the healing rate. As well, both types of nanofiber mats were able to combat microbial invasion into the wound bed. Conclusions Both binary polyvinyl alcohol/gelatin and ternary polyvinyl alcohol/gelatin/AgNPs nanofiber mats developed in the present study depicted similar regenerative and antimicrobial potential when applied as full-thickness wound dressing. However, in comparison to the binary nanofiber mats, no obvious synergistic effect was observed after loading nanofibers with AgNPs.

Prokineticins are highly conserved small peptides family expressed in all vertebrates, which contain a wide spectrum of functions. In this study, a prokineticin homolog (Bv8-AJ) isolated from the venom of frog Amolops jingdongensis was fully characterized. Bv8-AJ accelerated full-thickness wounds healing of mice model by promoting the initiation and the termination of inflammatory phase. Moreover, Bv8-AJ exerted strong proliferative effect on fibroblasts and keratinocytes isolated from newborn mice by activating interleukin (IL)-1 production. Our findings indicate that Bv8 is a potent wound healing regulator and may reveal the mechanism of rapid wound-healing in amphibian skins.
