Quantitative and 3-dimensional analysis of Langerhans' cells following occlusion with patch tests using confocal laser scanning microscopy
Emilson A, Lindberg M, Forslind B, Scheynius A.
Quantitative and detailed 3-dimensional (3-D) morphological information can be obtained from the same tissue volume using a confocal laser scanning microscope (CLSM). In the present study, we used CLSM for evaluation of Langerhans' cells (LC) in human skin at 0 h, 24 h and 48 h following occlusion with patch tests for 48 h. The relative volume of epidermal CD1a reactivity was quantified with CLSM ...

Skin disease in immunosuppressed patients in relation to epidermal Langerhans' cells.
Bergfelt L, Larkö O, Blohmé I.
Warts and skin tumours are common in renal transplant recipients (RTR). The increased susceptibility to skin lesions has been attributed to immunosuppressive treatments. The epidermal antigen-presenting Langerhans' cell (LC) is important for cutaneous immunosurveillance. The number of LC is reduced by UV light and by immunosuppressive therapy. One hundred and seventy-three immunosuppressed patient ...

Electrical measurement of the water content of the stratum corneum in vivo and in vitro under various conditions: comparison between skin surface hygrometer and corneometer in evaluation of the skin surface hydration state.
Hashimoto-Kumasaka K, Takahashi K, Tagami H.
Two commercially available electrical instruments which evaluate the hydration state of the skin surface were compared in in vitro and in vivo experiments. The skin surface hygrometer (Skicon-200) employs high-frequency conductance, whereas the corneometer (CM 420, CM 820) uses electrical capacitance to determine the level of hydration. In a simulation model of in vivo stratum corneum (SC), the hi ...

Water and ion distribution profiles in human skin.
von Zglinicki T, Lindberg M, Roomans GM, Forslind B.
Bulk sample x-ray microanalysis (XRMA) of human gluteal skin was performed to provide data on water and ion profiles over the epidermal cross section. All samples were analyzed both in the frozen hydrated state and in the frozen dried state. This allows, for the first time, a quantitative determination of the local water content in different strata of the skin. A steep water gradient was found in ...

Effects of short-time hydration on skin extensibility.
Auriol F, Vaillant L, Machet L, Diridollou S, Lorette G.
Vertical cutaneous extensibility was studied before and after 1, 2, 5 and 10 min hydration by application of tap water. After hydration, we noted an increase in all rheological parameters linked to elasticity whereas viscosity and hysteresis parameters were unmodified. These modifications took place from the first minute and increased thereafter. Men and women showed identical values prior to hydr ...
