Rubus sanctus protects against carbon tetrachloride-induced toxicity in rat isolated hepatocytes: isolation and characterization of its galloylated flavonoids. In summary, hepatocyte growth factor protection against bile acid‐induced apoptosis occurs via a phosphoinositide 3‐kinase pathway and is not dependent on the mitogen‐activated protein kinase pathway, phosphorylation of bad on serine 112, or activation of p70 s6 kinase. Introduction the liver is the largest internal organ and the largest gland in the body it plays an important role in complex metabolism and has numerous functions, including glycogen storage, lipid and protein synthesis, bile salt production, hormone production, and detoxification (hampsey and karnsakul, 2013. The present study was aimed to investigate the combined effect of curcumin[cmn] and vitamin e against ccl4 induced oxidative stress and liver toxicity in rats the toxicant ccl4 was used to induce liver toxicity at a dose of 1ml/kg as 1: 1 (v/v) mixture with liquid parafiin twice weekly for 8 weeks and sylamarinwas used as a standard drug to compare hepatoprotective effects of cmn and vitamin e. We therefore propose that erk phosphorylation induced by aza is a compensatory cell effect against its toxicity, a role suggested for menadione in rat hepatocytes (czaja et al, 2003) the role played by mitochondria in the aza-induced activation of mapk is unclear.
The relationship between the expression of mitochondrial voltage-dependent anion channels (vdacs) and the protective effects of myrica rubra sieb et zucc fruit extract (mce) against carbon tetrachloride (ccl4)-induced liver damage was investigated. Administration of various fractions of c opaca leaves extract with ccl4 showed protective ability against ccl4 intoxication by restoring the cardiac functions alterations, activities of antioxidant enzymes and lipid peroxidation in rat. Freshly isolated hepatocytes were adjusted to 1×10 6 /ml cell density in 10% fbs rpmi-1640 medium trypan blue staining to detect live hepatocytes showed more than 95% cell viability trypan blue staining to detect live hepatocytes showed more than 95% cell viability.
Advanced pharmaceutical bulletin (apb) is a peer-reviewed multidisciplinary international open access journal, covering a wide range of various integrative fields with pharmaceutical sciences. Additional experiments were designed to further study the role gsh plays in detoxication using isolated rat hepatocytes^ l-methionine protected against the extent of lipid peroxidation and leakage of the cytosolic enzyme, lactate dehydrogenase (ldh), caused by ch(,2)o in dem-pretreated hepatocytes, further supporting the protective role of gsh. Histopathology of liver also confirmed the protective effective of cynara against ccl4-induced hepatic damage gene expression measurements revealed that cynara administration ameliorated the effect of ccl4 that induced alterations in genes expression of apoptotic related genes bax, bcl-2 and caspase-3.
Kyung jl et al, (2008) eluciated protective effects of the saponins isolated from the root of platycodi radix (changkil saponins: cks) on carbon tetrachloride (ccl4)-induced hepatotoxicities in mice. Methods the acute liver injury model was established by intraperitoneal injection of ccl 4 in c57bl/6 mice serum alanine aminotransferase, aspartate aminotransferase, he staining and tunel assay were used to identify the amelioration of the liver histopathological changes and hepatocytes apoptosis after calycosin treatment. Pai-1 plays a protective role in ccl 4-induced hepatic ﬁbrosis in mice: role of hepatocyte division claudia von montfort,1,2 juliane i beier,1,2 j phillip kaiser,1,2 luping guo,1 swati joshi-barve,1,2. In this review article, we have discussed different studies in scientific databases including scopus, medline and web of science databases and local references, which investigate the antidotal and protective effects of saffron and its major components against natural toxins and chemical-induced toxicity. Furthermore, our observations in primary culture of rat hepatocytes showed that pedf and the 44-mer protected primary rat hepatocytes against apoptosis induced by serum deprivation and tgf-β1 pedf/44-mer induced cell protective stat3 phosphorylation.
Some natural compounds are demonstrated to have a protective role against liver diseases (pramyothin et al, 2007 pramyothin p, ngamtin c, poungshompoo s, chaichantipyuth c (2007) hepatoprotective activity of phyllanthus amarus schum. Hepatoprotective effect of total flavonoids from laggera alata against carbon tetrachloride-induced injury in primary cultured neonatal rat hepatocytes and in rats with hepatic damage cardioprotective role of leaves extracts of carissa opaca against ccl4. The aim of present study was to evaluate the protective role of melatonin in an in vitro model of isolated rat hepatocytes methods: markers such as cell viability, reactive oxygen species formation, lipid peroxidation, mitochondrial membrane potential, and hepatocytes glutathione content were evaluated every 60 minutes for 180 minutes. The present study is an attempt to evaluate the protective effect of diphenylmethyl selenocyanate — a synthetic organoselenocyanate against carbon tetrachloride (ccl4)‐induced hepatic damage in swiss albino mice in vivo.
Tpw was then evaluated against ccl4-induced liver toxicity in rats liver enzymes (ast, alt, and alp) and antioxidant markers were assessed the effect of tpw on isolated hepatic cells, post-ccl4 administration, was assessed by isolated mitochondrial membrane staining. Specifically, we were interested in evaluating the role of mirnas in the molecular pathogenesis of liver carcinogenesis in male b6c3f1/j mice treated with n-nitrosodiethylamine (den) or carbon tetrachloride (ccl4 ) alone or a combination of den and ccl4 and characterized by a differential tumor incidence that increased in the following order: den. This study suggests the protective role of taurine and/or melatonin against phenytoin‐induced cellular damage probably through their reactive radical scavenging properties and their effects on mitochondria.
Ugir hossain, sudin bhattacharya, protective effect of diphenylmethyl selenocyanate against ccl4-induced hepatic injury, journal of applied toxicology, 2007, 27, 6, 527wiley online library. To test the unique cytoprotective nature of ts in vivo, the protective ability of t and tocopherol esters against carbon tetrachloride (ccl4)-induced hepatotoxicity in rats was examined. The hepatoprotective effect of a melegueta methanol extract, sub-fractions and isolated compounds was investigated using carbon tetrachloride (ccl 4)-induced liver injury in a rat hepatocytes model.
And isolated hepatocytes, the relative contribution of the two pathways to quinone metabolism has been studied and a protective role for dt-diaphorase dem. Strated the protective role of sirt1 against oxidative stress 22 reproduction of a rat hemorrhagic shock model isolated hepatocytes were exposed to jc-1 (5. For more information on the individual ingredients in amazon liver support, a protective role against ccl4 toxicity in isolated rat hepatocytes.
