Antioxidant properties and Glutathione S-transferases inhibitory activity of Alchornea cordifolia leaf extract in Acetaminophen toxicity
Paracetamol (acetaminophen, PCM) is a widely used over-the-counter analgesic and antipyretic drug. Intake of a large dose of PCM may result in severe hepatic necrosis. Oxidative stress is mediated by oxidative capacities of the PCM metabolite (N-acetyl-para-benzo quinoneimine, NAPQI), which covalently binds to proteins and other macromolecules to cause cellular damage. At low doses, NAPQI is ...
متن کاملANTICONVULSANT THERAPY-INDUCED ALTERATIONS IN CALCIUM HOMEOSTASIS
35 epileptic patients, aged 10 to 58 years (mean 23), who were taking anticonvulsant drugs were studied. The patients exhibited a 34% reduction in serum calcium levels, a 41 % increase in serum alkaline phosphatase activity and a slight but insignificant decrease in serum phosphate, compared to untreated controls. These changes appear to be related to the anticonvulsant drug taken, in the ...
متن کاملCharacterization of acetaminophen toxicity in human kidney HK-2 cells.
Acetaminophen (APAP) overdose causes liver injury, but in some cases it is associated also with renal impairment. While several studies exist in relation to acetaminophen nephrotoxicity, no reports have been published describing intracellular changes related to APAP nephrotoxicity in vitro. Because proximal tubular cells are considered to constitute a secondary site of drug-induced injury after...
متن کاملGlutathione reductase is inhibited by acetaminophen-glutathione conjugate in vitro.
The aim of the present work was to investigate a new mechanism likely contributing to the toxic action of acetaminophen, especially to explore the possible inhibition of glutathione reductase through an acetaminophen-glutathione conjugate (APAP-SG). APAP-SG conjugate was synthesized by organic synthesis and purified by column chromatography. The inhibitory effect of the conjugate on two types o...
متن کاملMumijo Protection gainst Acetaminophen-Induced Acute Hepatic Injury: Role of Oxidative Stress
Background: A majority of people widely use acetaminophen as a sedative. Overusing the drug for prolonged periods of time can lead to acute liver damage. Mumijo, as a strong antioxidant and anti-inflammatory drug, could possibly reduce some of the acetaminophen-induced side effects on the liver. Thus, the aim of this study is to evaluate the effect of Mumijo on the liver damage...
