The aim of the current study was to investigate morphological and histological effects Bisphenol A on chicken Ross 308 during embryonic development total 150 eggs were randomly divided into five groups: negative control, positive control injected with con oil treatment groups administered different concentrations (0.005, 0.02 0.1 microliters/egg). second day incubation evaluation conducted days...

Introduction: There is little evidence of potential hepatotoxicity of Remdesivir (RDV), in vitro. Regarding the effective results of RDV in patients with COVID-19 and the impact of COVID-19 on liver function, we investigated the effects of RDV on the expression and activity of liver enzymes in chicken embryo-derived hepatocytes. Material and Methods: In this in vitro study, 20 embryonated chic...

UNLABELLED Alternative methods to whole liver transplantation require a suitable cell that can be expanded to obtain sufficient numbers required for successful transplantation while maintaining the ability to differentiate into hepatocytes. Mesenchymal stem cells (MSCs) possess several advantageous characteristics for cell-based therapy and have been shown to be able to differentiate into hepat...

This set of experiments is the first of a series designed to explore facets of cell proliferation of hepatocytes during the carcinogenic process induced in liver by chemical carcinogens. A rat model for hepatocarcinogenesis, the resistant hepatocyte model, was used. A major advantage of this model is the unusual degree of synchrony in the early steps. Carcinogenesis was initiated by the adminis...

L-methionine-dl-sulfoxide (MetO) is an L-methionine (Met) metabolite, but its role in Met metabolism and toxicity is not clear. In this study, MetO uptake, metabolism to Met, cytotoxicity, and glutathione (GSH) and glutathione disulfide (GSSG) status were characterized in freshly isolated mouse hepatocytes incubated at 37 degrees C with 0 to 30 mM MetO for 0 to 5 h. In male hepatocytes, dose-de...

In this study, we explored the paradox that in suckling rats the serum concentration of LDL is high although the liver secretes only minimal quantities of VLDL, the presumed precursor of LDL. Freshly isolated hepatocytes and hepatocytes in primary culture obtained from adult (90 days old) and suckling (17 days old) rats were used to investigate the synthesis and secretion of apolipoprotein B (a...

The effects of different concentrations of the hydroalcoholic extract of dried powdered leaves of Cichorium intybus L., on CCl4-induced hepatotoxicity in vivo in rats and CCl4-induced cytotoxicity in isolated rat hepatocytes were investigated. Rats received different concentrations of the extract by i.p. injection for 3 consecutive days before the injection of (3ml/kg) CCl4 (i.p.). Twenty four ...

The appropriate temperature and growth supplementary factors such as fetal bovine serum (FBS) are the necessities needed for cell growth in culture medium. In this regards, the effect of Leibovitz-15 (L-15) medium containing different concentrations of fetal bovine serum (FBS) was assessed on growth and proliferation of cultivated liver cells of klunzingerchr('39')s mullet, Liza klunzingeri, in...

The majority of hepatocytes isolated from rats treated with carcinogens (diethylnitrosamine plus 2-acetylaminofluorene) were found to be diploid, whereas most of the hepatocytes from normal rats are tetraploid. The carcinogen-induced diploid hepatocytes were only one-half the size (protein content) of the tetraploid hepatocytes, and could therefore be separated from the latter by centrifugal el...

In a genetically engineered V79 cell line (XEMd-MZ) expressing rat cytochrome P4501A2 the activity of phenacetin-O-deethylase was determined and compared with freshly isolated rat hepatocytes. In the V79 cells the apparent Km was 0.99 microM (N = 4), compared to the high affinity Km (0.23 microM, N = 4) found in freshly isolated rat hepatocytes, where as the Vmax found in the XEMd-MZ cells (14....
