lasiocarpine/fibrosis

Pyrrolizidine alkaloids have long been considered to be hepatotoxic in man as well as in grazing animals. To investigate the effect of liver cell division induced by thioacetamide on the hepatic changes induced by these alkaloids, rats were treated concurrently with thioacetamide and the

Lasiocarpine (LC), a pyrrolizidine alkaloid, is able to induce a series of chronic and progressive lesions in rat liver, including a long-lasting block in the cell cycle, the appearance of enlarged hepatocytes (megalocytosis), fibrosis, cirrhosis and malignant neoplasma. In this study the effect of

Herbal medication has gathered increasing recognition in recent years with regard to both treatment options and health hazards. Pyrrolizidine alkaloids have been associated with substantial toxicity after their ingestion as tea and in the setting of contaminated cereals have led to endemic outbreaks

Experimental pyrrolizidine alkaloid intoxication was produced in inbred Swiss mice. Animals were fed diets containing 0, 1, 3, 5, or 10% Heliotropium dolosum seed for 24 w. The seeds contained 0.13% total alkaloid concentration composed of 4 specific components: lasiocarpine (78.79%), heliosupine

Pyrrolizidine alkaloids (PA) are a group of secondary plant metabolites belonging to the most widely distributed natural toxins. PA intoxication of humans leads to severe liver damage, such as hepatomegaly, hepatic necrosis, fibrosis and cirrhosis. An acute consequence observed after ingestion of

Pyrrolizidine alkaloids (PA) are secondary plant metabolites that occur as food and feed contaminants. Acute and subacute PA poisoning can lead to severe liver damage in humans and animals, comprising liver pain, hepatomegaly and the development of ascites due to occlusion of the hepatic sinusoids

Pyrrolizidine alkaloids (PAs) are carcinogenic and genotoxic phytochemicals found exclusively in angiosperms. The ingestion of PA-containing plants often results in acute and chronic toxicities in man and livestock, targeting mainly the liver. During February 2014, a herd of 15-18-month-old
