Laboratory cultures of freshwater cyanobacterium (blue-green alga) Microcystis aeruginosa PCC 7806 was cvaluated for its hepatotoxic effects in rats. The lyophilized cell extract injected intraperitoneally at 1 and 2 LD50 (15.8 and 31.6 mg/kg, respectively) produced significant increase in liver-specific enzymes viz. plasma alkaline phosphatase,γ-glutamyl transferase, lactate dehydrogenase with a concomitant decrease in hepatic glutamic pyruvic transaminase. A corresponding increase in liver body weight index and histopathological changes in liver (degeneration of hepatocytes, congestion and hemorrhage etc.) are indicative of a dose and time dependent hepatotoxic nature of the algal extract 展开更多

Drug-induced liver injury(DILI)is one of the leading causes of liver failure and withdrawal of drugs from the market.A poor understanding of the precipitating event aetiology and mechanisms of disease progression has rendered the prediction and subsequent treatment intractable.Recent literature suggests that some drugs can alter the liver’s repair systems resulting in injury.The pathophysiology of DILI is complex,and immune dysfunction plays an important role in determining the course and severity of the disease.Immune dysfunction is influenced by the host response to drug toxicity.A deeper understanding of these processes may be beneficial in the management of DILI and aid in drug development.This review provides a structured framework presenting DILI in three progressive stages that summarize the interplay between drugs and the host defence networks. 展开更多

The porcine peptides at different doses were administered hepatotoxic mice to investigate their in vivo antioxidant capability. After administration, the activity of superoxide dismutase and glutathione peroxidase in liver and serum was enhanced and malonaldehyde content in liver and serum was greatly decreased. Therefore, the porcine peptides can significantly reduce the damage of active oxygen to body, enhance the body's antioxidant capability, and thus maintain health. 展开更多

Acute-on-chronic liver failure(ACLF)is a clinical syndrome that develops in patients with chronic liver diseases following a precipitating event and associated with a high mortality rate due to systemic multiorgan failure.Establishing a suitable and stable animal model to precisely elucidate the molecular basis of ACLF pathogenesis is essential for the development of effective early diagnostic and treatment strategies.In this context,this article provides a concise and inclusive review of breakthroughs in ACLF animal model development. 展开更多
