We studied the relationship between bilirubin concentrations in amniotic fluid and fetal blood in 68 non-hydropic rhesus d-alloimmunized anemic fetuses at first blood sampling. In these alloimmunized fetuses, the amniotic fluid/fetal blood ratio for bilirubin decreased from 0.09 at 28 weeks to 0.05 at 33 weeks. In normal fetuses, amniotic fluid/fetal blood ratios for bilirubin, and for albumin,...

Owing to the overlapping absorption bands of hemoglobin and bilirubin, spectrophotometric determination of plasma free hemoglobin has been plagued by the interference of bilirubin when the latter is present in significant concentrations. To resolve this problem, bilirubin oxidase from Myrothecium verrucaria has been used to remove bilirubin in icteric samples. The enzyme converts bilirubin to b...

The effects of rokitamycin (RKM), a macrolide antibiotic, on young rats with hyperbilirubinemia were investigated. RKM at a dose of 1,000 mg/kg was orally administered to 14-day-old rats with hereditary, non-hemolytic hyperbilirubinemia (homozygous Gunn rats, total plasma bilirubin concentration: about 7 mg/dl). Animals given 10 ml/kg of 0.5% carboxymethyl cellulose (CMC) were used as control. ...

BACKGROUND AND OBJECTIVE Bilirubin/albumin ratio (B/A) may provide a better estimate of free bilirubin than total serum bilirubin (TSB), thus improving identification of newborns at risk for bilirubin encephalopathy. The objective of the study was to identify thresholds and compare specificities of TSB and B/A in detecting patients with acute and posttreatment auditory and neurologic impairment...

A technique is described for preparation in the guinea pig of an in situ, isolated, vascularized gall bladder that exhibits normal absorptive functions. Absorption of labeled bile pigments from the gall bladder was determined by the subsequent excretion of radioactivity in hepatic bile. Over a wide range of concentrations, unconjugated bilirubin-14C was well absorbed, whereas transfer of conjug...

Faldaprevir, an investigational agent for hepatitis C virus treatment, is well tolerated but associated with rapidly reversible, dose-dependent, clinically benign, unconjugated hyperbilirubinemia. Multidisciplinary preclinical and clinical studies were used to characterize mechanisms underlying this hyperbilirubinemia. In vitro, faldaprevir inhibited key processes involved in bilirubin clearanc...

bilirubin induced brain damage is still a common cause of morbidity and mortality in nigerian infants. no much success has been recorded in decades despite the fact that brain damage from bilirubin toxicity in the newborn is easily preventable with affordable and effective means. we report a case of a newborn with acute bilirubin encephalopathy. this case was considered of interest because the ...

The gold standard to assess jaundice in neonates is the serum bilirubin measurement. Blood sampling for the determination of total serum bilirubin (TSB) is painful for newborns and stressful for parents. The Bilicheck®, a new transcutaneous bilirubinometer, is considered as a more accurate measurement of bilirubin compared to the previous bilirubinometers courtesy of its advanced technology. Th...
