We have undertaken to determine whether kynurenic acid production or excretion in the bile (as reported by Kotake and Ichihara) might be responsible, at least in part, for the choleretic effect of tryptophane. We have also studied the influence of optical configuration of tryptophane on bile volume and on bile salt output, both of which Whipple and Smith found were increased by l-tryptophane administration.
