Synergistic action of sodium selenite and N-acetylcysteine in acetaminophen-induced liver damage

Human & Experimental Toxicology
Ss YalçinM Ozdemir

Abstract

Acetaminophen (AAP) is a commonly used analgesic and antipyretic drug; however, when used in high doses, it causes fulminant hepatic necrosis in both humans and experimental animals. In this study, we investigated whether selenium (Se) and N-acetylcysteine (NAC), alone or in combination, are protective against AAP toxicity in mice. At the beginning of the experiment, blood samples were taken from 10 of 350 mice. Then, the remaining mice were randomly allocated into four groups, each consisting of 35 animals. The 1st group received a single administration of AAP by gavage at a dose of 600 mg/kg-bw, p.o. The 2nd group (AAP-Se) was treated with sodium selenite (0.5 mg Se/kg-bw, p.o.) one hour after ingestion of AAP. The 3rd group (AAP-NAC) ingested AAP, 1.5 h later followed by NAC (500 mg/kg-bw, p.o.). The 4th group (AAP-Se-NAC) was given sodium selenite and NAC, 1 and 1.5 h after administration of AAP, respectively. From each group, blood samples of seven mice for each time point were taken at 4, 8, 24, and 48 h after AAP toxicity. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH) levels were measured. Compared with AAP group, the levels of ALT were lower after AAP ingestion in AA...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.
