Parvovirus of Aleutian disease causes mainly damage to kidneys, but immune complexes deposition and damage may occur also in other organs. In mink farms of Latvia the liver dystrophy or hepatic lipidosis of mink is widely distributed. The goal of this study was to examine probability of liver damage and regeneration of mink infected with Aleutian disease virus. Liver injury was assessed histolo...

Tissue damage caused by viral hepatitis is a major cause of morbidity and mortality worldwide. Using a mouse model of viral hepatitis, we identified virus-induced early transcriptional changes in the redox pathways in the liver, including downregulation of superoxide dismutase 1 (Sod1). Sod1(-/-) mice exhibited increased inflammation and aggravated liver damage upon viral infection, which was i...

Methamphetamine-induced neurotoxicity has been correlated with damage to the liver but this damage has not been extensively characterized. Moreover, the mechanism by which the drug contributes to liver damage is unknown. This study characterizes the hepatocellular toxicity of methamphetamine and examines if hyperthermia contributes to this liver damage. Livers from methamphetamine-treated rats ...

conclusions the di was found to induce liver damage by oxidative stress mechanisms. silibinin reduced the oxidative stress by inducing antioxidant mechanisms, thereby showing protective effect against di induced liver damage. further studies with silibinin should be performed regarding di toxicity. materials and methods thirty two wistar albino rats were divided into four groups, as follows: 1)...

Background: In hepatic transplantation, inflammatory response related to liver ischemia-reperfusion injury is an important cause of hepatocellular damage that may lead to organ dysfunction. This project aims to develop a new method of dynamic imaging for the local analysis of hepatic function using un-metabolized 99mTc-labeled mebrofenin excretion time in the bile canaliculi as a read-out. Meth...

Background: Activation of inflammatory cells can cause more chemicals induced-hepatotoxicity. Aflatoxin B1 (AFB1) is a fungal toxin that induces acute hepatotoxicity in humans and animals. This study was conducted to examine the effect of co-exposure LPS and various aflatoxin B1 doses on the damage hepatic parameters in isolated perfused rat liver. Methods: Thirty-two male wistar rats (250-3...

BACKGROUND & AIMS During endotoxemia, expression of inducible nitric oxide synthase (iNOS) and nitric oxide production in the liver is increased. NO has been suggested to have a hepatoprotective function. The aim of this study was to investigate the distribution of iNOS and the effect of different NO synthase inhibitors on liver damage and hemodynamics during endotoxemia. METHODS Rats were in...

acrolein (acr) is α, β unsaturated aldehyde that exists extensively in the environment and (thermally processed) foods. it can also be generated through endogenous metabolism. the aim of this study was to investigate the possible protective role of pentoxifylline (ptx) is a non-selective phosphodiesterase (pde) inhibitor on toxicity of acr. in this study, oxidative damage were measured by marke...

Liver regeneration from the facultative hepatic stem cells, the oval cells, takes place in situations in which liver regeneration from pre-existing hepatocytes is prevented. Different models have been used to stimulate oval cell response. Many of them involve the use of carcinogenic agents with or without partial hepatectomy. In this study we show that adenovirus-mediated gene transfer of the s...

Objective(s): In this study, we evaluated the therapeutic effects of casticin and myricetin on liver  damage induced by methotrexate in rats.Materials and Methods: Thirty-six male rats were used for the study and divided into 6 groups: control, methotrexate, casticin, myricetin, casticin+methotrexate, and myricetin+methotrexate. It was performed by methotrexate (20 mg/kg single dose, IP) in met...
