Ultrastructural changes of the skin induced by human leukocyte elastase and cathepsin G.
Glinski W, Kuligowski M, Pierozynska-Dubowska M, Glinska-Ferenz M, Jablonska S
Human neutrophil elastase and cathepsin G at a concentration of 10(-6) M were found to attack various substrates when normal skin biopsy specimens were incubated at 37 degrees C for 1 h with either of these enzymes. Elastase damaged primarily hemidesmosomes, leading to the epidermal cleavage from the dermis, whereas cathepsin G damaged the membrane structures. Both these neutral proteinases were h ...

Melanosome complexes and melanin macroglobules in normal human skin.
Bartosik J
The presence of melanin macroglobules, and sometimes that of melanosome complexes also, in epidermal melanocytes has been considered a feature of various skin diseases. Opinions differ as to whether these structures can occur in normal skin. We have studied these melanin inclusions in normal Caucasian skin in the entire soma of 116 melanocytes and the occurrence of melanosomes in phagosomes of 77 ...

Terbinafine levels in serum, stratum corneum, dermis-epidermis (without stratum corneum), hair, sebum and eccrine sweat.
Faergemann J, Zehender H, Jones T, Maibach I
We determined terbinafine levels in serum, stratum corneum, dermis-epidermis (without stratum corneum), hair, sebum and eccrine sweat before, during and after 250 mg doses orally to volunteers once daily. Terbinafine is concentrated rapidly in stratum corneum (up to 9.1 micrograms/g of tissue) primarily by diffusion from the vascular system through the dermisepidermis. It also reaches high concent ...

Topical cyclosporin induces hair growth in human split skin grafted onto nude mice.
Gilhar A, Etzioni A, Moscona R
Previously we observed that systemic CyA induces hair growth in an experimental model of human scalp skin graft transplanted onto nude mice. In the present study we investigated the role of topical CyA in the murine transplantation model, using human split-thickness skin grafts (HSTSG). Ten mice grafted with 1-mm-thick skin and another 10 mice grafted with 0.4-mm-thick skin were treated topically ...

Release and absorption of zinc from zinc oxide and zinc sulfate in open wounds
Agren MS, Krusell M, Franzén L.
The pharmacokinetic behaviours of zinc oxide and zinc sulfate when applied as single doses to full-thickness excised rat skin wounds were studied. In the zinc oxide group, the wound fluid zinc concentration increased slightly over the 48-h postoperative period due to increased solubilization of zinc oxide, attributed to increased protein concentration of the wound fluid. When zinc sulfate was appl ...

Differentiation of the basal cell epithelioma-like changes overlying dermatofibroma.
Fujisawa H, Matsushima Y, Hoshino M, Baba T, Uyeno K
Epidermis overlying dermatofibroma rarely displays basal cell epithelioma-like changes (BCE-like changes). Based on the histopathological findings, whether BCE-like changes are induced by dermal lesion or adnexal regression secondary to the solid fibrotic growth remains to be explored. From the standpoint of differentiation, we examined the BCE-like changes overlying dermatofibroma, normal epiderm ...

A case report of acute febril neutrophilic dermatosis (Sweet's syndrome) and Crohn's disease.
Beitner H, Nakatani T, Hammar H
A case of Crohn's disease complicated by Sweet's syndrome is presented. The main ultrastructural findings were the multiplication of basal lamina surrounding the venulea, interendothelial gaps and in perivascular locations mixed infiltrates of neutrophiles and erythrocytes. The changes indicate that the initial site of the reaction was the walls of the dermal vessels.
