Abstract
Lymphocyte subpopulations were studied in 45 PUVA treated patients and in 45 controls matched for sex and age. The results demonstrate that, in vivo, PUVA induces a decrease in the capacity of the E-Rosette formation by lymphocytes separated from the peripheral blood. However, the circulating lymphocytes count remains unchanged. Mitogen induced blastogenesis is not affected. No correlation is found between the decrease in the level of E-rosettes, the disease which motivated PUVA therapy, the energy in UVA and the number of irradiation. Electrical and/or chemical modifications on the cell surface of the lymphocytes during PUVA therapy are postulated to explain this phenomenon. Subpopulationen von 45 mit PUVA behandelten Patienten und entsprechenden 45 Kontrollen wurden untersucht. Es zeigt sich, daß in vivo die PUVA-Behandlung eine Verminderung der E-Rosettenbildung durch Lymphocyten bewirkt. Die zirkulierenden Lymphocyten bleiben jedoch unverändert. Die durch Mitogene induzierte Plastogenese wird nicht beeinflußt. Es wird keine Korrelation zwischen der Abnahme der E-Rosetten, der Dermatose, welche zur PUVA-Therapie führte, und der Energie des UVA und der Zahl der Bestrahlungen gefunden. Offenbar werden die verschiedenen Effekte durch elektrische bzw. chemische Veränderungen der Zelloberfläche während der PUVA-Behandlung hervorgerufen.This publication has 33 references indexed in Scilit:
