[Climate therapy of psoriasis: critical evaluation].

As with many chronic, recurrent skin diseases, psoriasis in all its forms is within the domain of dermatological climatotherapy. However, this is only successful in genuinely stimulating climates, such as in the North Sea islands or in particularly high alpine regions (over 1500 m) under correct topographical conditions. If dermatological climatotherapy is to retain its justifiably good name, care must be taken not to misuse this important therapeutic means (unsuitable climates), or it may be discredited due to insufficient conditions and thus poor results.

[Modification of relative amount of free amino acids in the stratum corneum of human epidermis by special factors of the environment. I. The influence of UV-irradiation (author's transl)].

By repeated uv-irradiation the quantity of all free amino acids (per surface unit) in human horny layer increase considerably. 4 different groups of substances are found by taking the relative values in mole per cent. 1. No difference for urea, threonine, serine, glutamine, tyrosine and ammonia. 2. Decrease of about 20 p.c. for glutaminic acid, citrulline, arginine, histidine. 3. Increase of about 20 p.c. for urocanic acid, aspartic acid, proline, glycine, valine, isoleucine. 4. The rest of amino acids increase about 30--50 p.c.
