Provocation tests with antiphlogistica and food additives in recurrent urticaria.

100 patients (53 women, 47 men) suffering from recurrent urticaria were tested with different food additives such as 8 dye additives, 7 preservatives and 7 antiphlogistica. In total did 62 patients react with urticaria and/or angio-oedema. 39 patients had reactions to two or more substances while 23 patients reacted to only one substance. Reactions were induced most frequently by aspirin (27/80), dextropropoxyphene (11/45) and the azo dyes tartrazin (20/96) and sunset yellow (13/86/. Asthmatic symptoms occurred in 3 and purpura in 2 patients. 13 patients out of 100 reported of immediate reactions to different foods.

Genotoxicity studies of the food additive ester gum.

Ester gum (EG) is used in citrus oil-based beverage flavourings as a weighting or colouring agent. In the present study, concentrations of 50, 100 and 150 mg/kg body weight were administered orally to male Swiss albino mice, and sister chromatid exchange and chromosomal aberration were used as the cytogenetic endpoints to determine the genotoxic and clastogenic potential of the food additive. Although EG was weakly clastogenic and could induce a marginal increase in sister chromatid exchange frequencies, it was not a potential health hazard at the doses tested.
