In general, rats and mice have not been used in research on emesis because they do not vomit. However, emetogenic stimuli such as anticancer drugs, apomorphine, copper sulfate and rotation induced pica, a behavior characterized by eating nonfood substances such as kaolin, in rats. We also found that cisplatin induced pica in mice, but it was rather difficult to determine the exact kaolin consumption in this species. In this study, we prepared kaolin pellets mixed with carmine, a dye not absorbed in the gastrointestinal tract, and estimated kaolin consumption by determination of carmine excreted in feces. Cisplatin (5 mg/kg) caused a significant increase in kaolin consumption (saline: 0.15 +/- 0.08 g vs. cisplatin: 0.45 +/- 0.16 g) and pretreatment with the 5-HT3 receptor antagonist, ondansetron (2 mg/kg), suppressed the increased consumption (vehicle: 0.33 +/- 0.05 g vs. ondansetron: 0.13 +/- 0.04 g). These findings suggested that the exact kaolin consumption could be quantified by the determination of carmine in feces and that mice could be useful for studying emesis.
