Abstract
Livergol (LG), which is the extract of Silybum marianum and commonly known as milk thistle possess hepatoprotective effect.
Orally administered LG significantly suppresses Bromobenzene (BB)-induced increases in serum activity of enzymes AST, ALT, ALP.
Treatment with LG has improved hepatic damages due to BB severe degeneration and vacuolation of hepatocytes.
Based on the results the efficacy of LG in MEs showed better drug solubility and permeability which lead to improve drug absorption among different biological membranes.
The hepatoprotective effect of this formulation against BB toxicity has been conducted through the control release, high diffusion and absorption rates and improve and increase in oral bioavailability of active pharmaceutical agents.
Livergol (LG), which is the extract of Silybum marianum and commonly known as milk thistle possess hepatoprotective effect and have got licensed for sale in Iran and other countries. LG was evaluated for its capacity to counteract the toxic effects of bromobenzene (BB) on mouse liver. The bioactive component of this plant is known to reinforce naturally occurring liver function through antioxidant activity, the stimulation of bile production and regeneration by the liver organ, resulting in enhanced protection against toxicants, hepatitis, and cirrhosis. The major bioactive components of this product are the flavonolignan ssilibinin, silidianin, silicristin, and isosilibinin. Mice were treated for 10 days with daily gavage of microemulsions (MEs), into which 0–400 mg/kg LG was dispersed. 0.36 ml/kg BB was injected intraperitoneally (ip) to each animal on day 10, followed by sacrifice on day 11, and histological evaluation of hematoxylin-eosin (HE)‐stained liver tissue samples, afterwards followed by evaluation liver enzymes level, aminotransferase (AST), alanine aminotransaminase (ALT) and alkaline phosphatase (ALP) activities. Significant suppression of BB-mediated damage to liver tissue, and increased in AST, ALT, and ALP level was observed to occur dose-responsively with LG administration, suggesting a use for LG as a chemoprotectant for persons chronically exposed to industrial solvents.
