Human toxicity is a general term refers to any substance which causes harm to human health if inhaled, ingested or absorbed through the skin.
Liver stress is a condition in which the function of the liver is partly reduced. Hepatic stress can be observed by the levels of liver stress-makers, including transaminases aspartate transaminase (AST) and alanine transaminase (ALT).
Epidemiologically, drugs that induce liver injury are nonsteroidal anti-inflammatory drugs (NSAIDs), anti-infective drugs (anti-tubercular drugs), anti-cancer drugs, hormonal drugs, immunosuppressive agents, sedative and neuropsychiatric drugs.
Acetaminophen according to study is the most form of medication that implicates drug-induced liver injury
However, antibiotics are the class of drugs that cause liver toxicity most commonly
Conventionally, treatment of liver toxicity is totally depending on the types of inducers, including
* Management of drug-induced liver injury by discontinuing the suspected drug.
* Acetaminophen poisoning is treated by antidote N-acetylcysteine.
* Glucocorticoids are used for the treatment of the immune-mediated drug-induced liver injury.
* Intravenous N- acetylcysteine is used for the treatment of non-acetaminophen-related acute liver failure
Tomatoes provide about 80% of the lycopene in the world diet. In plants, lycopene protects the host against excessive photodamage and perform various functions in photosynthesis.
On finding a potential compound for the prevention of liver injury, researchers investigated the potential oxidative damage of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in hepatic microsomal fractions in an animal model.
The study included rat liver microsomes that were divided into four groups.
* Group I served as a control and is incubated with vehicle (toluene).
* Groups III and IV with 15 nM of TCDD for further 1 h.
Based on the tested analysis, groups treated by TCDD showed a significant increase in liver oxidative stress observed by increasing levels of Hydrogen peroxide (H2O2) production, lipid peroxidation (LPO),
Furthermore, the activity of antioxidant enzymes superoxide dismutase, glutathione peroxidase, catalase, glutathione-S-transferase, and glutathione reductase and the microsomal thiol content produced by the rat liver microsomes were significantly decreased in the TCDD treament groups.
Lycopene treatment group IV not only normalized the activities of the enzymes, thiol and carbonyl content but also significantly reduced LPO and H2O2 production.
