title: [A 13-week toxicity study of simultaneous administration of cochineal and aluminum potassium sulfate in rats].
abstract: Cochineal (C), a scarlet material extracted from the powdered pregnant insect, Dactylopius Coceus Costa, is used as a color food additive in the form of aluminum lakes. A 13 week subchronic toxicity study was conducted to investigate the effects of simultaneous administration of C and aluminum potassium sulfate (A). Male and female Wistar rats (5-weeks-old, 15 rats/group) were given diets containing 0.75%A and 0.75%C (1.5%AC), 1.5%A and 1.5%C (3%AC), 3%C alone or 3%A alone. The following results were obtained. 1) No toxic symptoms or death occurred in any treated group. Body weight gain in male rats of the 3%A group decreased significantly. 2) Serum levels of phospholipids, triglycerides (TG) and total cholesterol in male rats and TG in female rats fed 3%C, 3%A or 3%AC were significantly decreased at the 13th week. The serum level of glutamate dehydrogenase (GIDH) in male rats treated with 1.5% or 3%AC was increased at the 4th week but no difference from control was observed at the 13th week. 3) No histopathological changes attributable to A and/or C administration were observed. In this 13-week oral toxicity study, no dose-dependent synergistic effects of simultaneous administration of C and A were found except for an increase in serum GIDH.
