The conversion of hematin to bile pigment.
The role of hem&in in hemoglobin and bile pigment metabolism is not clearly defined. Opinion has been divided over the questions of whether or not hematin is a normal degradation product of hemoglobin and whether or not it is converted to bile pigment. Bingold observed that the occurrence of hen&in in the plasma is associated with a variety of pathologic conditions (1). The conditions in which ...
متن کاملOrigin of Bile Pigments
S. H. ROBINSON (Boston) described a new experimental technique for studying the early labelled component of bilirubin in the ligated bile duct of the Gunn rat. Using 14C bilirubin he measured the total miscible bilirubin pool. In addition, the rate of bile pigment formation following the administration of 2-14C glycine was estimated. This allowed precise assessment of bilirubin and haem product...
متن کاملBile pigments in the stools of infants.
In the normal person bilirubin is converted in the gut into stercobilin. However, unaltered bile pigment occurs in meconium and in the stool of any individual with much intestinal hurry, and has also been shown to be passed at times by some older infants, though this fact does not seem to be widely known. The absence of stercobilin from the stool is usually takenasevidence for total biliary obs...
متن کاملBile Pigments in Pulmonary and Vascular Disease
The bile pigments, biliverdin, and bilirubin, are endogenously derived substances generated during enzymatic heme degradation. These compounds have been shown to act as chemical antioxidants in vitro. Bilirubin formed in tissues circulates in the serum, prior to undergoing hepatic conjugation and biliary excretion. The excess production of bilirubin has been associated with neurotoxicity, in pa...
متن کاملLv. Studies on Bile Pigments
THE study of bile pigment derivatives is important because these substances represent the end-products of haemoglobin metabolism. The destruction of haemoglobin both normal and pathological can thus be measured by quantitative determination of the urobilin and urobilinogen in urine and faeces. On the other hand, when pathological destruction of haemoglobin can be excluded, urobilinor urobilinog...
