No effects on food consumption, drinking water consumption and
mortality. No treatment-related changes of organ-weights and in
histopathology. There was a dose-related red coloration of the urine of
all animals in the test groups which was seen beginning from day 14 of
the treatment. Urine analysis gave no indication of any toxicologically
relevant deviations. A decrease in total protein and globulins was noted
for the male animals of the high dose group at the end of the
administration period. The coloration of urine and gut mucosa as well as
of the mesenteric lymph nodes does not represent a toxic effect but
proves that Basazol Gelb 8511 or one of its metabolites is resorbed by
the organism. The disappearance of the coloration demonstrates that the
test substance is eliminated from the organism during the treatment-free
The NOAEL is between 180 mg/kg bw and 60 mg/kg bw.
