Effects of aluminum on the liver following high-dose enteral administration to rats

Abstract

Parenteral administration of aluminum (Al) to animals can result in hepatobiliary dysfunction, including elevated total serum bile acid concentration, reduced bile flow, and reduction of mixed function oxidase activities. Despite substantial hepatic Al accumulation, biliary Al excretion is negligible. We studied the effects of enteral administration of pharmacologic doses of Al to rats in order to see if by this route Al also produced hepatobiliary dysfunction or if biliary Al excretion was enhanced following enteral administration, protecting the liver from the effects of Al. Six rats were given 100 mg/kg/day of Al for 14 days as Al citrate by duodenal cannula. Pair-fed littermate controls were given sodium citrate. Serum Al and urinary Al/creatinine were significantly higher in Al-fed rats than in controls. Liver Al was significantly increased in the Al-fed group, but very low when compared to liver Al concentration with intravenous Al administration. Biliary Al was only 2 +/- 1% of urinary Al in the experimental group. Serum bile acid concentration and bile flow were not different between groups. We conclude that Al given in pharmacologic doses is absorbed but does not accumulate in the liver. We hypothesize that a slow rate...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.
