Pregnant rats received 14C-Carmoisine (200 mg kg-1; 25 microCi) by gavage on days 16-19 of gestation. The animals were killed and maternal tissues, amniotic fluid, placentae, foetal membranes and foetuses were analyzed for radioactivity. No evidence for the transplacental transfer

14C-Carmoisine (250/ug; 1.25 x 10(6) dpm) was incubated under strictly anaerobic conditions with resting cell suspension from stool specimens collected from male rats and human male healthy adults. The kinetics of azoreduction was determined as amount of naphthionic acid (NA)
