The polymerase chain reaction and dermatology. A new technique with important implications for the study of skin inflammation and for diagnostic tests of dermatological disorders.
Paludan K, Thestrup-Pedersen K.
The polymerase chain reaction is a powerful and versatile tool for the analysis of nucleic acids. Through a reaction imitating in vivo DNA replication, a defined fragment of DNA is repeatedly replicated by a DNA polymerase in an exponential manner. Such selective amplification of a sequence of interest has created new possibilities in molecular biology and related sciences. The basic principle and ...

Topical indomethacin aggravates the weal and flare response in chronic dermographic urticaria: evidence for a new class of histamine receptors
Sharpe GR, Shuster S.
The effect of topical indomethacin on the weal and flare response was measured in 9 patients with chronic dermographic urticaria. An augmentation of dermographic wealing by topical indomethacin was shown with lowering of the weal threshold from 22.3 +/- 4.7 g/mm2 (mean +/- SEM, n = 9) to 16.4 +/- 3.8 (p < 0.005), but without a change in the shape of the force/response curve. Flare was increased by ...

Serum alpha 1-protease inhibitor levels in patients with chronic idiopathic urticaria.
Imai S.
A comparative study of serum alpha 1-protease inhibitor levels in patients with chronic idiopathic urticaria and control subjects revealed that the values in the patients were significantly lower than those in the controls, especially in patients over 60 years. The results suggests that some protease which can be inhibited by alpha 1-protease inhibitor may be involved in urticarial reactions in pa ...

Freeze-fracture electron microscopic and osmotic water permeability studies of epidermal lipid liposomes derived from stratum corneum lipids of porcine epidermis.
Mandal TK, Downing DT.
Freeze-fracture electron microscopic studies revealed that the liposomal membrane morphology was intact before and after osmotic treatment. This finding suggested that water leakage from the liposomes was not due to fusion of two or more lipid vesicles, but rather to the osmotic salt effect. A stop-flow spectrophotometric study revealed that epidermal lipid liposomes derived from stratum corneum l ...

Transepidermal water loss and water content in the stratum corneum in infantile seborrhoeic dermatitis.
Tollesson A, Frithz A.
Thirty-seven patients with clinically diagnosed infantile seborrhoeic dermatitis (ISD) were studied in an attempt to establish the significance of transepidermal water loss (TEWL) and water content in the stratum corneum, in active disease and after recovery. All the patients were treated daily with topically applied borage oil (containing 24% gamma-linolenic acid). With this regimen they were com ...

Quantification of contact allergic inflammation: a comparison of existing methods with a scanning laser Doppler velocimeter.
Quinn AG, McLelland J, Essex T, Farr PM.
Responses to a range of doses of common contact dermatitis-producing allergens were measured using a novel scanning laser Doppler velocimeter and three commonly used conventional measurement techniques. The techniques were compared in terms of sensitivity, measurement error, range of the linear portion of the dose-response curve and ease of use. The detection thresholds of the objective methods di ...

Photodynamic properties of Sn-protoporphyrin: clinical investigations and phototesting in human subjects.
Emtestam L, Angelin B, Berglund L, Drummond GS, Kappas A.
Pure synthetic metalloporphyrins have been developed for experimental and clinical use as inhibitors of heme oxygenase, the rate limiting enzyme in the catabolism of heme to bilirubin. Tin (Sn)-protoporphyrin is one such compound, which potently suppresses bilirubin production and thus jaundice in animals and man. We have previously reported that this metalloporphyrin in conjunction with UVA might ...

Use of scale antibodies for the detection of antigens in psoriatic lesions.
Iversen OJ, Bergh K, Lysvand H.
Extractable IgG from psoriatic scale was purified, labelled with biotin and used in ELISA and immunofluorescence (IF) in an attempt to detect and localize prominent antigens in psoriatic scale extracts and in psoriatic lesions, respectively. Biotinylated immunoglobulins isolated from psoriatic scale from each of 5 patients were used. Scale extracts were fractionated on a Sephacryl S-300 column, an ...

Increase of endothelaemia in psoriasis.
Arenberger P, Buchtová L, Hladovec J.
Changes of blood vessel endothelium in psoriasis have not been fully documented in the literature. The aim of our study was to ascertain whether in cases of such involvement an increase of endothelaemia could be identified. The counts of circulating endothelial cells were significantly increased in psoriatics compared with healthy individuals and patients with atopic eczema. The explanation of thi ...

Down-regulation of epidermal growth factor receptors by dithranol.
Kemény L, Michel G, Arenberger P, Ruzicka T
Dithranol is highly effective in the treatment of psoriasis, but the exact mechanism of action is not known. Since persistent expression of epidermal growth factor (EGF) receptors in psoriatic epidermis is assumed to have pathogenetic significance, we have studied the effects of dithranol on EGF binding to the human epidermal cell line SCL-II. After treatment of cells with dithranol or its therape ...

Ultrastructural localization of superoxide dismutase in human skin.
Kobayashi T, Saito N, Takemori N, Iizuka S, Suzuki K, Taniguchi N, Iizuka H.
The ultrastructural localization of copper and zinc superoxide dismutase (Cu,Zn-SOD) and manganese superoxide dismutase (Mn-SOD) was investigated in normal human skin by the post-embedding immunogold staining method. Epidermal keratinocytes were positive for both Cu,Zn-SOD and Mn-SOD. The Cu,Zn-SOD was predominantly located in the cytoplasm with a slight labelling on the mitochondria. The basal ce ...

Autotransplantation in vitiligo: treatment with epidermal grafts and cultured melanocytes.
Zachariae H, Zachariae C, Deleuran B, Kristensen P.
Previous studies have shown the usefulness of autologous grafts carrying melanocytes for treatment of vitiligo. In our study repigmentation was obtained in three patients using epidermal sheets from suction blisters. The repigmentation was found stable in follow-ups from one to three years. The most homogenic repigmentation, however, was found in a patient treated by grafting autologous melanocyte ...
