In the present study, we examined the role of indoleamine 2,3-dioxygenase (IDO) in the development of CCl4-induced hepatic fibrosis. The liver fibrosis induced by repetitive administration with CCl4 was aggravated in IDO-KO mice compared to WT mice. In IDO-KO mice treated with CCl4, the number of several inflammatory cells and the expression of pro-inflammatory cytokines increased in the liver....

Article history: Received on: 09/12/2015 Revised on: 27/12/2015 Accepted on: 12/01/2016 Available online: 27/02/2016 This study is conducted to investigate the prophylactic effect of thymoquinone (TQ), the major active ingredient of Nigella sativa seeds, against carbon tetrachloride (CCl4)-induced hepatic damage in Sprague-Dawley (SD) rats. Forty rats were divided into four even groups. The fir...

Chemokines play a pivotal role in regulating the immune response through a tightly controlled expression. Elevated levels of inflammatory chemokines commonly occur with aging but the mechanism underlying this age-associated change is not fully understood. Here, we report the role of microRNA-125b (miR-125b) in regulating inflammatory CC chemokine 4 (CCL4) expression in human immune cells and it...

Background Astaxanthin is of carotenoids group which possess strong antioxidant properties. The present study was conducted to evaluate the hepatoprotective effects of astaxanthin in carbon tetrachloride (CCl4)-treated rats. Materials and Methods Female Long-Evans rats were administered with CCl4 orally (1 ml/kg) twice a week for 2 weeks and were treated with astaxanthin (10 mg/kg) every day ...

Anti-oxidant effects of propofol (2, 6-diisopropylphenol) were evaluated agains carbon tetrachloridet CCl4 -induced oxidative stress in rat liver. 30 male rats were equally divided in to 6 groups (5 rats each). Group I (control), while Group II was given CCl4 (3 mL /Kg/day, IP). Animals of Groups III received only propofol (10 mg/Kg/day, IP). Group IV was given propofol+ CCl4. Group V was admin...

Mechanisms of chloroform (CHCl3) and carbon tetrachloride (CCl4) toxicity to primary cultured male B6C3F1 mouse hepatocytes were investigated. The cytotoxicity of both CHCl3 and CCl4 was dose- and duration-dependent. Maximal hepatocyte toxicity, as determined by lactate dehydrogenase leakage into the culture medium, occurred with the highest concentrations of CHCl3 (5 mM) and CCl4 (2.5 mM) used...

BACKGROUND In Pakistan numerous medicinal floras has used in the treatment of various human ailments. Among them Trifolium alexandrinum L. is traditionally used in the curing of disease. Presently we designed to ascertain the protective role of Trifolium alexandrinum methanolic extracts (TAME) against carbon tetrachloride (CCl4)-induced lung injury and oxidative stress in rats. METHODS Exposu...

BACKGROUND Liver diseases are major global health problems. Ginseng extract has antioxidant, immune-modulatory and anti-inflammatory activities. This study investigated the effect of ginseng extract on carbon tetrachloride (CCl4)-induced liver fibrosis in rats. METHODS Male Wistar rats were divided into four groups: control group, ginseng group, CCl4 group and CCl4 + ginseng group. Liver inju...

Stress as a cofactor has been reported to affect the progression and severity of liver diseases. The present study investigated the effect of chronic restraint stress on carbon tetrachloride (CCl4)-induced liver fibrosis. A total of 30 male BALB/c mice were randomly divided into three groups: Oil-treated control group; CCl4-treated group; and CCl4 + restraint-treated group. CCl4 was administrat...
