Red cell destruction and bilirubin production in adult rats with short-term biliary obstruction

Abstract

The rate of total bilirubin production and the concomitant relative rate of early-labeled bilirubin (ELB) formation were studied in adult Wistar rats with short-term common bile duct ligation. The pulmonary excretion rate of CO (VeCO), an index of total bilirubin production, was measured preoperatively and postoperatively on day 3 and on day 5 or 6. While the VeCO measurements of control and experimental animals were similar preoperatively, the postoperative VeCO measurements of the experimental animals averaged 30% higher than those of control animals. On postoperative day 3, the relative rate of ELB formation was measured by the recovery of excreted 14CO after the administration of 14C-labeled delta-aminolevulinic acid (ALA) or glycine as nonerythropoietic or total heme synthesis precursor, respectively. No significant differences were found in the 14CO recovered from either compound during the study period between the experimental and control animals. The half-life of 51Cr-labeled transfused red blood cells was decreased by nearly 50% in bile duct ligated rats compared to that in the sham operated ones. We conclude that hemolysis is a major factor contributing to the increase in total bilirubin production even after short-te...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
