The ultrastructure of treponema pallidum isolated from human chancres. Morphologic variations from Nichols´ strain
Poulsen A, Kobayasi T, Secher L, Weismann K.
The ultrastructure of treponema pallidum obtained directly from human chancres by biopsy was studied by electron microscopy. The treponemes were enveloped by a trilaminar cytoplasmic membrane and a trilaminar periplastic membrane. The central part of the periplastic membrane corresponds to the protective mucoid layer. In undamaged organisms bunches of axial filaments were seen to entwine the whole ...

Relative efficiency of human Langerhans´ cells and blood derived dendritic cells as antigen-presenting cells
Bjercke S, Braathen L, Gaudernack G, Thorsby E.
T4 cells recognize antigens together with HLA class II molecules in the membrane of antigen-presenting cells (APC). The magnitude of the induced T cell response is in part dependent upon the APC´s amount of MHC-class II molecules. Langerhans´ dendritic cells (LC) express 50-100 times more HLA-DR molecules than monocytes (Mo) and blood derived dendritic cells (DC). We report here that LC are more ...

Studies on fibronectins in the skin. VIII. Influence of corticosteroids on cell cultures from normal human skin
Fyrand O.
Fibronectins are important glucoproteins of mesenchymal tissue. Fibronectins are also found in the human skin, and tissue cultures demonstrate the production of soluble dimers and insoluble fibrous polymers from dermal fibroblasts. Under the influence of different glucocorticoids, inhibited production of these fibronectins from cultured human skin cells is demonstrated.

Immunophenotyping of the dermal cell infiltrate in lichen planus treated with PUVA
Naukkarinen A, Väätäinen N, Syrjänen KJ, Horsmanheimo M.
To evaluate the immunoregulatory mechanisms in lichen planus (LP) responding to PUVA therapy, the LP skin lesions of eight patients were biopsied before and after treatment with trioxsalen baths and UVA. The percentages of B, T, and MPS (monocyte-macrophage) cells as well as OKT-4+ (helper) and OKT-8+ (suppressor) T cells were calculated. OKT-8+ T cells were the dominating cell type in untreated L ...

Experimental pruritus evoked by platelet activating factor (PAF-acether) in human skin
Fjellner B, Hägermark O.
Cutaneous pruritic effects of synthetic platelet activating factor (PAF-acether) and, in particular, its interference with dermal mast cells, were studied in human volunteers. Intradermal injections of 10-100 ng produced dose-dependent flare and itching responses. The cutaneous reactions were inhibited by local administration of the H1 antihistamine mepyramin. The cutaneous responses were also mar ...

Protein content of comedones from patients with acne vulgaris
Bladon PT, Cooper NF, Cunliffe WJ, Wood EJ.
Characteristic early lesions in acne vulgaris are the open and closed comedones (blackheads and whiteheads) which are well known to contain a "plug" of cornified material. Histological analysis of these lesions has indicated that their protein content, presumed in part to be keratin, may be degraded, possibly by bacterial action, though this has never been adequately demonstrated biochemically. We ...

Dry hands in scleroderma. Including studies of sweat gland function in healthy individuals
Serup J, Rasmussen I.
Complaints of dry hands were evaluated in 68 patients with generalized scleroderma (GS) and 66 healthy individuals (HI) for comparison. Studies included evaporimetry of the hands and forearms as performed under physiological conditions indicating sweat gland function. Complaints of dry hands were more frequent (p less than 0.001) in GS (71%) than in HI (32%) as was the use of emollients (68% and 3 ...

Enzyme production of propionibacteria from patients with acne vulgaris and healthy persons
Höffler U, Gehse M, Gloor M, Pulverer G.
375 strains of propionibacteria isolated from pustules, comedones, and from normal skin of patients with acne vulgaris and from healthy persons have been examined for their enzymatic activity. In contrast to healthy individuals, protease and caseinase production of strains from acne patients was significantly lower. On the other hand, DNA´ase production of strains from acne lesions was increased, ...

Oxidation of dopa in human albinism
Carstam R, Hansson C, Krook G, Rorsman H, Rosengren E, Wirestrand LE.
The urine of an albino woman contained small quantities of 5-S-cysteinyldopa; 6-hydroxy-5-methoxyindole-2-carboxylic acid, a melanin precursor metabolite, was lacking. The 5-S-cysteinyldopa excretion observed may reflect non-specific oxidation of dopa. Two other albino patients showed normal values for the excretion of 5-S-cysteinyldopa and of 6-hydroxy-5-methoxyindole-2-carboxylic acid.

Urinary excretion of 5-S-cysteinyldopa and 6-hydroxy-5-methoxyindole-2-carboxylic acid: differences between pigmented and albino mice
Ekelund MC, Carstam R, Hansson C, Rorsman H, Rosengren E.
Urinary excretion of the phaeomelanin precursor 5-S-cysteinyldopa (5-S-CD) and the eumelanin metabolite 6-hydroxy-5-methoxyindole-2-carboxylic acid (6H5MI-2-C) was studied in black and albino mice. The urinary concentration of 5-S-CD was 31.7 ng/ml in black and 16.1 ng/ml in albino mice. The concentration of 6H5MI-2-C was 21.0 ng/ml in the urine of black mice. The compound could not be demonstrate ...

Kveim test reactivity in Melkersson-Rosenthal syndrome (cheilitis granulomatosa)
Lindelöf B, Eklund A, Lidén S.
The relation between the Melkersson-Rosenthal syndrome (MRS) and sarcoidosis is unclear. The Kveim test, a test for sarcoidosis, was performed in seven patients, two with complete and five with abortive forms of Melkersson-Rosenthal syndrome. All were found to be negative. Serum levels of angiotensin converting enzyme and calcium were normal. These facts make it unlikely that MRS is a type of sarc ...

Ultraviolet light therapy in chronic urticaria
Hannuksela M, Kokkonen EL.
Fifteen patients with chronic urticaria were treated with ultraviolet light B (UVB) for 1-3 months during the spring 1984 and a follow-up study was performed in November 1984-January 1985. Patients with cold urticaria, cholinergic urticaria and dermographism became clearly better or got rid of their symptoms more often than those with "non-specific" chronic urticaria. The good results achieved dur ...

Treatment of chancroid with enoxacin
Mensing H.
Chancroid (ulcus molle) was treated in 7 male patients with enoxacin (2 X 400 mg/die). Microbiological and clinical examinations proved complete healing in all cases after 7 to 12 days. No side effects were mentioned. Enoxacin seems to be an excellent alternative treatment for this sexually transmitted disease.
