Intercellular lamellar lipids in plantar stratum corneum.
Egelrud T, Lundström
Plantar stratum corneum was examined by means of transmission electron microscopy after conventional osmium fixation and after fixation with ruthenium tetroxide. The latter fixative was used in order to reveal the possible existence of lamelarly ordered lipids in the intercellular space, as has previously been demonstrated for non-palmo-plantar stratum corneum. A major part of the plantar stratum ...

The hydrating effect of a cream and white petrolatum measured by optothermal infrared spectrometry in vivo.
Petersen EN
Optothermal infrared spectrometry (OTIS) is a novel way of measuring the water content of stratum corneum non-invasively. This principle has been used in the present study to evaluate the hydrating effect of a one-week treatment of human skin twice a day with either white petrolatum or a cream (o/w emulsion). Forty-two females volunteered for the study, which comprised one control pretreatment wee ...

Production of interleukin-2 by mononuclear cells in vitro in patients with atopic dermatitis and psoriasis. Comparison with serum interleukin-2 receptor levels.
Kapp A, Neuner P, Krutmann J, Luger TA, Schöpf E
Atopic dermatitis is associated with profound immunological alterations, in particular decreased lymphoproliferative responses upon stimulation with T-cell mitogens. T-cell blastogenesis involves the production of the soluble cytokine interleukin-2 (IL-2), which in turn upregulates the expression of its own receptor. To investigate the potential role of this cytokine for the pathomechanisms presen ...

Stigmata of atopic constitution in patients with atopic eczema or atopic respiratory disease.
Przybilla B, Ring J, Enders F, Winkelmann H
In the diagnosis of atopic eczema, minor physical markers (stigmata) frequently provide valuable clues. The prevalence of nine stigmata (dry skin, hyperlinearity of the palms or soles, infraorbital fold, white dermographism, facial pallor, orbital darkening, Hertoghe's sign, low hairline) was evaluated in 34 atopic eczema patients without atopic respiratory disease, in 16 patients with allergic rh ...

RNA purification from epidermal suction blisters.
Kristensen M, Larsen CG, Jørgensen P, Paludan K
Certain inflammatory skin diseases are accompanied by increased cytokine concentrations in the epidermis. To determine whether these cytokines are synthesized in the epidermis or exported from underlying tissues, epidermal RNA was analysed for the presence of their messenger RNAs. We report a method for RNA extraction from pure epidermal samples isolated by the suction blister method. The yield of ...

Reactivity of HMB-45 monoclonal antibody with sweat-gland tumours of the skin.
Kanitakis J, Hermier C, Chouvet B, Thivolet J
HMB-45, a monoclonal antibody claimed to be specific for malignant melanoma, has been observed to react with normal eccrine sweat glands and occasionally with normal mammary and bronchial epithelium. In this study we show that HMB-45 also decorates cells in approximately 15% of various sweatgland tumours of the skin. This finding, along with the reported reactivity on mammary carcinomas further ou ...
