摘要:

In a retrospective study on a selected group of patients, the coincidence of birch pollen allergy and a clinically relevant positive prick test reaction to apples and potatoes was confirmed.Immunochemical comparison using the crossed line immunoelectrophoresis technique (CLIE) confirmed partial identity between birch pollen and hazelnut. By the same method no partial immunological identity between birch pollen and extracts and fresh peel from apples and potatoes was found. However, both apples and potatoes gave rise to non‐immunological affinity precipitates. On this basis it is discussed, whether the active agents from apples and potatoes were extremely labile allergens, plant lectins, or low molecular weight substances with a direct or indirect histamine release effec

摘要:

The effects of topical applications on the living human forearm skin of 3 ml of DMSO 0.09 % JaCI in water solutions of various concentrations during a variety of exposure times were evaluated clinically, and with water vapour loss and impedance measurements. The water vapour loss measurement appeared not to be a sensitive parameter, since it showed only deviations from normal values if there were also clinical signs of irritation, e.g. if the skin is exposed during 15 min to a DMSO solution of 90 % or higher. Impeddance showed some increase after 15‐min exposures to 30 % DMSO. In the range of 60 to 99.9 % DMSO, decreases of impedance were found increasing progressively with strength of solution and duration of exposure. Only the longer exposures (3 h to 60 % DMSO) or the higher concentrations (90 % DMSO and over during 15‐min exposure) produced clinical signs.Daily repeated short‐lasting (5–10 min) exposures to carefully chosen concentrations of DMSO (60, 73 and 86 %revealed that the skin of the volunteer was almost able to resist the lowest concentration. If exposed for 10 min the skin had some difficulty in recovering from the irritating influence of exposures to 60 or 73 % DMSO which took place the preceding day: there is some tendency to a progressive lowering of resistance. With repeated 5‐min exposures to 86 % DMSO, this tendency to progressive lowering of resistance is more evident although there is a clear but somewhat incomplete recovery 24 h after each preceding exposure. If the skin is exposed daily to 86 % DMSO for 10 min. the regenerative capacity after the 12th exposure is exhausted.However, after the 17th exposure, extra regenerative forces seem to be mobilized restricting progressively the consequences of every exposure to follow. If the skin is no longer exposed (day 21), recovery is speedier and more complete than that seen after the 5‐min exposures to the same strength. We propose calling this ‘adaptation’

摘要:

A case of occupational chrysanthemum contact dermatitis is reported. Patch tests showed the patienttobe sensitized toChrysanthemum morifolium(Chr M) leaves, flowers, and stems (alcoholic extracts) and to alantolactone. An attempt at desensitizalion appears to have been successful.Gas chromatography indicated the presence of alantolactone in all the various parts of Chr M, mostly in the flowers.The “maximization test” succeeded in sensitizing guinea pigs to alantolact

摘要:

A new way of expressing the concentrations of patch test allergens solutions (or emulsions) is proposed. From these new expressions it can be seen that apparently similar concentrations (0.5 % chromium, 1 % formaldehyde) can actually be in the ratio 1 to 15 as expressed at the molecular level.

摘要:

In recent years the importance of internal exposure to nickel in patients with recurrent hand eczema and nickel allergy has become evident. The present study was performed in order to investigate the value of urinary nickel determinations as an index of oral nickel intake. After oral administration of 5.6 mg nickel (as the sulfate), increased nickel excretion was found over the following 2–3 days. We conclude that consecutive urinary nickel determinations are able to disclose variations in oral intake of nicke

摘要:

Three patients employed in the manufacture of plastic tennis rackets developed allergic contact dermatitis to isophorone diamine (IPD), an epoxy resin hardener, and con‐comitantly to epoxy resin.Patch tests were positive to IPD at 1, 2 and 5 % in olive oil and to IPD at 1, 2 and 5 % in ethanol.Investigations were conducted in control subjects to confirm the allergic nature of reactions. A review of the literature about IPD and related compounds is presente
