摘要:

To white paraffin containing potassium dichromate in various concentrations (0.5, 0.1, 0.05 and 0.01%) the following emulsifiers were added: 10% glycerol monostearate; 10% Tween 60, and 3% Span 20. Patch tests were performed with these bases and the amount of Cr VI released in vitro was determined. All the three emulsifiers enhanced, though to a different extent, chromium release in vitro from bases containing 0.5% dichromate. In bases containing 0.05 and 0.01%, release was enhanced only by glycerol monostearate. The effect of all three emulsifiers in vivo differed: glycerol monostearate distinctly enhanced, Tween 60 somewhat reduced, and Span 20 did not visibly affect the sensitivity of the patch test.

摘要:

The percutaneous resorption of mercury (mercuric phenylborate, mercuric oxycianide and white precipitate ointment) has been investigated in 25 patients by measuring the urinary excretion of mercury. No significantly raised values were found after application of mercury on large areas of the body over several days. Only in one patient with a disturbed renal function was there an increase in the excreted mercury. The question is discussed how far one is allowed to draw conclusions on percutaneous resorption of mercury on the basis of the urinary excretion.

摘要:

An acid deoxyribonuclease of guinea pig epidermis hydrolyzes chromatin DNA as well as histone-free DNA. The enzyme degrades approximately 50% of chromatin DNA, while it degrades 90% of histone-free DNA. Guinea pig epidermal extract contains proteolytic activity for histone or chromatin with a pH optimum at around 8.0.

摘要:

Five cases of urticaria pigmentosa in patients of different ages and of both sexes were studied for mast cell changes and alkaline phosphatase activity. It has been found that mast cells were very rich in the enzyme as indicated by the black colour after the Gomori’s stai

摘要:

Skin surface biopsies taken from normal and parakeratotic skin and stained with a 4-4-diamidinodiphenylamine dihydrochloride (M & B 938) were examined microscopically using bright field and ultraviolet light illumination. No fluorescence was seen in squames from normal skin when microscopically examined using ultraviolet light illumination. In marked contrast, brilliantly fluorescent nuclei were observed in squames from parakeratotic skin. Control preparations treated with DNAse and stained with M & B 938 did not exhibit nuclear fluorescence. The fluorochrome is not specific for DNA since it stains cartilage and goblet cells and appears to behave as a basic dye.

摘要:

Two cases of aplasia cutis congenita are presented. The first case was in a child with a localized defect on her scalp. The second case was in an adult male who had extensive symmetrical involvement of his trunk and thighs, two lesions on the scalp and dystrophic changes in his nails. Nail dystrophy associated with aplasia cutis congenita has been described only once previously.

摘要:

A case of type V hyperlipoproteinemia manifested by eruptive xanthoma and lipemia retinalis is described. The patient also had an accelerated ESR, leukocytosis and hyperhidrosis. His karyotype was found to be XXY, which is typical of Klinefelter’s syndrome. The possible relationship between type V hyperlipoproteinemia and Klinefelter’s syndrome is discus

摘要:

A 9-year-old Japanese girl with generalized pustular psoriasis (GPP) had a linear epidermal nevus (LEN) which exhibited psoriasislike features in a noneruptive phase of GPP. In advance of the exacerbation of the disease, crops of confluent pustules appeared on the linear lesions and afterwards continued during the flare-up. Although several cases of ordinary psoriasis with a LEN presenting inflammatory changes have been reported, it seems that there is only one paper in the literature concerning pustular formation on a LEN in a patient with GPP. This particular phenomenon may be interpreted as a kind of Koebner reaction in a person with active GPP.
