In order to establish whether the increased B.S.P. secretion in the bile following phenobarbital administration is the consequence of change in the bile output or represents a consequence of the enzymatic induction, the dynamics of the elimination of 131J-B.S.P. was studied in animals treated with ANIT and Phenobarbital in the conditions of isolated perfused liver. At the same time the levels of the conjugation enzyme of B.S.P. were also determined. It was noted that after Phenobarbital the biliary elimination of 131J-B.S.P. is in correlation with the important increase of the output; in the animals treated with ANIT, on the other hand, the biliary excretion of B.S.P. is minimal. The biliary elimination is directly proportional to the increased of the bile output and reflects the changes found in the perfusate. Our findings allow us to assume that the increased of the bile output and in a smaller extent the result of the stimulation B.S.P. conjugation with Gluthation.
