[Mechanism of mediators in human skin. Pharmacoanalysis and therapeutic aspects].

Under physiological and pathological conditions, the skin is influenced by tissue hormones (biogenic amines, kinines, prostaglandines), neuro-hormones (acetylcholine, catecholamines) and by proteins as complement. The combination of neurological stimulation with a series of self-propagating metabolic changes, shows new aspects of tissue reaction. Histamine triggers a serie of mediators as kinines and prostaglandines. Due to their influence on mediators and their effects on regulatory mechanisms the cyclic nucleotides can serve as model substances for the development of therapeutic processes for dermatological as well as for other disorders. The influence on mediator-systems by topical treatment and proven permeability of such substances is of extreme importance for the future development of local dermatological therapy.
