...M. Brassinne; G. Pierard The extension border of lesions of psoriasis vulgaris has been studied by histogeometric analysis of the epidermis and by autoradiography after in vitro incorporation of tritiated thymidine. The first modification observed is a hyperactivity of in the suprabasal layer...

...W. Wohlrab; W. Böhm The epidermis thins in response to short-term contact with urea, and the results of extensive enzymological and autoradiographical studies suggest that urea acts on processes involved in epidermal proliferation. After long-term exposure of skin to urea, lasting more than 2, 4...

...B.M. de Rey; R.L. Cabrini The response of the epidermis to the effects of actinomycin D was analyzed at ultrastructural level. Important cellular alterations were found at 40 h post injectionem. The degree of nucleolar segregation varied depending on the epidermal layer assayed. Analogies...

...W. Wohlrab The thinning of epidermis after urea treatment is explicable theoretically in several ways. We take the estimation of epidermal DNA synthesis measured autoradiographically by 3 H-thymidine incorporation for a valid contribution to solve this question. As a result, the number of labeled...

...P.D. Mier; José J.M.A. van den Hurk The use of synthetic fluorogenic substrate has been applied to the measurement of lipase from guinea pig epidermis. The enzyme is not inhibited by Triton X-100 in concentrations up to 2 mg/ml, has a pH optimum in the range 6.5–8.5, a Km of 1.0 × 10 –– 6 mol/l...

...David T. Woodley The zone of human skin between the epidermis and dermis is called the dermal-epidermal junction (DEJ). The importance of the DEJ is outlined and three new areas of research involving the DEJ are reviewed: the intracellular pool of bullous pemphigoid antigen, the interactions...

... to induce major conformational changes in the protein. The technique was then used for the study of RBP in human epidermal and dermal extracts; this showed that RBP degradation with loss of binding properties for retinol occurred within the epidermis. A polyacrylamide gel electrophoresis binding assay...

...Peter M. Elias Since metaplasia and gap junction stimulation are prominent features of retinoid activity in embryonic and neoplastic epidermis, it is ironic that the mechnism(s) of retinoid action in postnatal tissues, where these drugs are employed clinically, appears to be different. Histologic...

...C. Piérard-Franchimont; A. Colige; J. Arrese Estrada; C.M. Lapière; G.E. Piérard We have raised a polyclonal antibody to the 170-kD epidermal growth factor receptor. We found an intercellular pattern of immunoreactivity in the epidermis as well as a positivity of the cytoplasm of keratinocytes...
