A complication of diabetes is the inability of wounds to heal in diabetic patients. Diabetic wounds are refractory to healing due to the involvement of activated matrix metalloproteinases (MMPs), which remodel the tissue resulting in apoptosis. There are no readily available methods that identify active unregulated MMPs. With the use of a novel inhibitor-tethered resin that binds exclusively to...

The ability to heal wounds is vital to all organisms. In mammalian tissues, alterations in intermediate filament (IF) gene expression represent an early reaction of cells surviving injury. We investigated the role of keratin IFs during the epithelialization of skin wounds using a keratin 6alpha and 6beta (K6alpha/K6beta)-null mouse model. In skin explant culture, null keratinocytes exhibit an e...

The possibility to use a suspended tridimensional matrix as scaffolding for re-epithelialization of in vitro cutaneous wounds was investigated with the aid of a human in vitro wound healing model based on viable full thickness skin. Macroporous gelatin microcarriers, CultiSpher-S, were applied to in vitro wounds and cultured for 21 days. Tissue sections showed incorporation of wound edge kerati...

We present a case of successful superficial keratectomy and amniotic membrane grafting to re-establish ocular surface from denuded stroma and significant limbal ischemia caused by a cement splash. We fully documented a case report about the sequels, complications and management strategies of a chemical burn to the eyes associated with a cement splash. Slit lamp examination, visual acuity test a...

During early morphogenesis, tissue segregation is often accompanied by changes in cell shape. To understand how such coordination is regulated, somitogenesis was used as a model. When a somite forms in the anterior end of the presomitic mesoderm, an intersomitic boundary (gap) emerges, and it is rapidly followed by cell epithelialization at this border. It has been known that the gap formation ...

A major difference between the non-regenerative (scar-forming) wound closure found in mammals and the regenerative wound closure (scarless healing) found in many fish and salamanders is that reepithelialization of the injury is much faster in animals that can regenerate appendages [1]. This reepithelialization, in turn, is essential for appendage regeneration. Methylene blue dye has long been u...

OBJECTIVES The study was undertaken to evaluate the burn wound healing property of oil of Cocos nucifera and to compare the effect of the combination of oil of Cocos nucifera and silver sulphadiazine with silver sulphadiazine alone. MATERIALS AND METHODS Partial thickness burn wounds were inflicted upon four groups of six rats each. Group I was assigned as control, Group II received the stand...

In this study, Tetrapleura tetraptera was ascertained of its effect on wound healing. The Lethal dose (LD50) of Tetrapleura tetraptera was determined and the research on its wound healing effect was carried out. The standard method of Nofal was adopted for the determination of the (LD50). Wound healing effect was done by excising wounds on anaesthesized rats and then the percentage wound closur...
