THE biological breakdown of haem proceeds through a series of intermediates of which the orange-yellow bile pigment, bilirubin, the chromophore responsible for coloration in the various forms of jaundice, is a key member. In the adult human, for example, erythrocytes have a lifetime of about 3 months and their destruction produces about 300 mg ...

CRYSTALLINE bilirubin changes with time as noted by Kuster1. Newly recrystallized, it dissolves immediately and completely in chloroform. With aged preparations, when dissolved at room temperature, a certain amount of insoluble substance is observed which dissolves within a few seconds when boiled under reflux.

In babies of low birth weight dying in the first week of life, bilirubin encephalopathy involving the thalamus only or the thalamus and one or two other areas occurred in nineteen of 376 cases examined over a 10 year period. Although coexistent germinal layer haemorrhage was present in sixteen, this was not thought to be an aetiological factor.

Gli autori hanno studiato l'azione della luce sulla stabilita della bilirubina in soluzione alcalina e in soluzione cloroformica. Viene proposto, in via generate, un meccanismo del primo ordine per la trasformazione della bilirubina in pigmenti verdinoidi, sia per le soluzioni irradiate, sia per quelle conservate al buio.

Peripheral blood specimens from cases of varying degree of clinical severity of hemolytic disease of the newborn infant have been examined spectrophotometrically and a curve consistent with the presence of bilirubin was found in each case. Extracts of the pigmented brain areas from five cases of hemolytic disease of the newborn infant ...

On the autoxidation of bilirubin
Biochemical and Biophysical Research Communications, 1976Abstract The instability of oxygenated aqueous solutions of bilirubin in the dark is due to several distinguishable processes: autoxidation, surface phenomena and precipitation-aggregation. Autoxidation occurs in aqueous solutions over a pH range 7.4–13.2 in the presence of even traces of oxygen.

JAUNDICE has classically been considered to be due either to impaired excretion of bilirubin by the liver or to overproduction of this pigment as the result of hemolytic disease.

Per azione della luce ultravioletta la bilirubina disciolta in CHCl3-CH3OH somma una molecola di metanolo fornendo un prodotto per il quale si dimostra la struttura III. Tale reazione, osservata anche con altri alcooli, suggerisce la possibilita che parte della bilirubina del siero dei neonati itterici sottoposti a fototerapia venga eliminata sotto ...

Effects of bilirubin and its photoisomers on direct bilirubin measurement using bilirubin oxidase
Annals of Clinical Biochemistry, 2000We examined the reactivity of human serum albumin-bound bilirubin and its photoisomers as substrates for a direct bilirubin assay using bilirubin oxidase. The reduction of (EZ)-cyclobilirubin reached 100% 5 min after addition of the enzyme at any pH tested (3·5–7·4) in 0·1 mol/L phosphate buffer, whereas the reduction of (ZE)-bilirubin or (ZZ ...
