ARIAS, IRWIN M., LOIS JOHNSON, AND SONIA WOLFSON. Biliary excretion of injected conjugated and unconjugated bilirubin by normal and Gunn rats. Am. J. Physiol. 200(5) : I 091-1094. I 961. -Conjugated and unconjugated bilirubin were injected intravenously at different times into normal rats and homozygous, jaundiced Gunn rats. As was expected, Gunn rats did not excrete injected unconjugated bilir...

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...

Extract of Methanol:ethanol (70:30) of Prunus domestica was prepared and tested for its hepatoprotective effect against Paracetamol and CCl4 induced hepatitis in rats . Alteration in the levels of biochemical markers of hepatic damage like SGPT, SGOT, ALP,Total bilirubin, direct bilirubin and tissue LPO, GSH, catalase and SOD were tested in both treated and untreated groups. Paracetamol (2 g/kg...

The Jendrassik--Groff assay for direct bilirubin was adapted for analysis rates of 150/h on the Technicon "SMAC" continuous-flow analyzer. This requires development of a standard that is compatible with the other 19 channels on this analyzer. N-1-Naphthyl ethylenediamine dihydrochloride has been used for standardization of direct bilirubin assays, but we found it to be unsuitable because values...

We used an enzymatic method for measuring total bilirubin in serum. Results by this method varied linearly with bilirubin concentrations to at least 300 mg/L. The day-to-day precision (CV) of the method ranged from less than 1% to about 11% at bilirubin concentrations of 183 and 12 mg/L, respectively. Commonly used anticoagulants, serum preparation materials, and selected drugs had no effect on...

This prospective study was conducted to evaluate the accuracy of transcutaneous bilirubinometry in preterm newborns less than 32 weeks of gestation. Serum bilirubin values measured by direct spectrophotometry were considered as standard, the range was 2.2-12.5 mg/dL. 32 jaundiced infants of less than 32 weeks of gestation without phototherapy, including 10 ELBW neonates, were enrolled. Close co...
