Cytoprotective effect of silybin against lasalocid-induced toxicity in HepG2 cells [PDF]

, 2013
Lasalocid is an ionophore coccidiostatic agent frequently used in poultry. Its extensive use causes the formation of residues in edible tissues and eggs which may pose a risk to consumers. Silybin is the main compound extracted from the herb milk thistle
