  • Skin Human skin is a complex integration of different types of cells and tissues which form an organ. Skin is also the primary seat of the sense of touch and creates a covering for the protection of th ⁇ deeper tissues. The skin also plays an important role in the regulation of body temperature and is also an excretory and absorbing organ. Skin consists primarily of a layer of vascular tissue and an external covering of epithelium known as the epidermis. On the surface layer are the sensitive papillae and alongside or imbedded beneath it are certain specialized organs, specifically the sweat glands, hair follicles, and sebaceous glands.
  • wounds which are caused by physical means, result in a disruption of the normal continuity of the structures of the skin. Examples of wounds include cuts, punctures, lacerations, etc.
  • stomach lining is also composed of internal epithelium (endotheliu ).
  • Gastric ulcers are a result of damage or erosion of the stomach lining. Gastric ulcers occur along the lesser curvature of the stomach where the pyloric glands border the oxyntic gland. They are usually 1 to 2.5 cm in diameter; however, they can vary from a few mm to several cm. Ulcers are usually round, oval or elliptical, with sharply defined margins. The surrounding mucosa is often hyperemic and edematous. Ulcers penetrate into the submucosa or muscular layer.
  • a thin layer of gray or white exudate usually covers the base of the ulcers; this layer is composed of fibrinoid, granulation and fibrous tissue layers.
  • fibrous tissue in the base contracts the ulcer and may distort the surrounding tissue.
  • healing continues as granulation tissue fills the base and epithelium from the ulcer edges cover its surface.
  • the mechanism of epithelial wound healing is a complex process involving ultrastructural changes of epithelial cells. These changes allow for detachment from neighboring cells, migration and subsequent reattachment.
  • the migration of epithelial cells has been found to depend on a suitable matrix composed of fibrin, fibronectin or basement membrane which traverse the wound. Clark, R., J. Am. Acid Derm.. 13:701-718 (1985); Zitelli, J., Adv. Dermatol . 2:243-268 (1987).
  • the process involves clotting and formation of a crust or scab to seal the wound; an acute inflammatory reaction; reepithelialization of the surface and fibrous bridging due to fibrin followed by complete sealing of the wound by an epithelial covering. Thereafter, hair follicles, sebaceous glands and sweat glands may subsequently regenerate.
  • the process of second intention healing requires the removal of necrotic debris. The gap in the wound then fills in with fibrous materials.
  • carbenoxolene is used to treat gastric ulcers.
  • Carbenoxolene is a hydrolytic product of glycyrrhizic acid (derivativ of licorice); it has been shown to increase the rate of gastric ulce healing. Braunwald, E., Harrison's Principles of Internal Medicin 11th ed. p. 1247. It appears to increase the life span of gastri mucosal epithelial cells and increase the secretion and viscosity o gastric mucus.
  • carbenoxolene has aldosterone-like effects, therefore it tends to increase the rate at which the body retain sodium and water. These effects may be blocked by aldosterone antagonists, however the antagonists obliterate the healing effects o the carbenoxolene. There is a need for therapies which can promot healing without the negative side effects.
  • the skin may be a targe tissue for 1,25-(0H) -D3 (Stumpf, W.E. et al.. Science. 201:1188-119 (1979)).
  • Cells isolated from the skin of rats, mice, and humans, an from cultured human skin fibroblasts and keratinocytes contain a hig affinity (1.0 x 10 "10 M) low capacity receptor-like protein for 1,25 dihydroxyvitamin D3 (Franceschi, et al .. Arch. Biochem. Biophys. 210: 1-13 (1979); Simpson, R. U. et al., P.N.A.S. (USA). 77: 582 (1980); Colston, K. et al..
