Objective- The liver has a unique location in the body for performing multiple functions such as,metabolism, detoxification and synthesis. There are limitation for liver transplantation due to shortage ofavailable donors and requires for sophisticated technology and support surgical teams. The purpose of thisstudy was to investigate the hepatocyte transplantation into the spleen of animal model...

The isolation of primary hepatocytes from liver tissue farm animals yields a very high number cells, and part them can be stored by cryopreservation for future experiments. As no experience exists with the cattle, our study aimed at bovine use different protocols compared pig. We tested freezing media (William’s Medium E vs. University Wisconsin solution), cryoprotectants (dimethyl sulfoxide wi...

ATP binding cassette transporter A1 (ABCA1) limits the formation of high density lipoproteins (HDL) as genetic loss ABCA1 function causes virtual HDL deficiency in patients with Tangier disease. Mice a hepatocyte-specific knockout (Abca1 HSKO) have 20% wild type (WT) plasma HDL-cholesterol levels, suggesting major contribution hepatic to phenotype. Whether sphingolipids are reduced disease and ...

     It has been proposed that organic nitrates such as glyceryl trinitrate (GTN), used in the treatment of cardiovascular diseases, act by producing nitric oxide (NO). However, the biochemical pathway for NO formation from GTN is not well understood. In the present study, we showed that nitrate formation from GTN, by isolated rat hepatocytes, was inhibited about 50% when cellular glutathione w...

-Continuous labelling of urethane induced pulmonary adenomata in adult male A2G mice at intervals up to 20 weeks showed that the growth fraction fell progressively from 18% at 7 weeks to 70, at 20 weeks. This fall appears to be wholly responsible for the decrease in production of adenoma cells with age. A fraction labelled mitoses curve was constructed for pulmonary adenomata at 14 weeks post u...

      Addition of n-butyl nitrite to isolated rat hepatocytes caused an immediate glutathione depletion followed by an inhibition of mitochondrial respiration, inhi- bition of glycolysis and ATP depletion. At cytotoxic butyl nitrite concentrations, lipid  peroxidation  occurred  before  the  plasma  membrane  was  disrupted. Cytochrome P-450 inhibitors inhibited peroxynitrite formation and prev...

Modulatory effects of l-carnitine, acetate, propionate, and 5-tetradecyloxy-2-furoic acid (TOFA; an inhibitor acetyl-CoA carboxylase) on oxidation esterification [1-14C]-palmitate were studied in hepatocytes isolated from phlorizin-treated control wethers. Our hypotheses that (1) palmitate would be greater sheep injected with phlorizin; (2) l-carnitine increase more (3) acetate propionate decre...

The micronucleus (MN) assay in human exfoliated cells has been widely used to detect the genotoxic effects of environmental mutagens, infectious agents and hereditary diseases. Substantial variability characterizes the MN frequencies reported by different research groups. One reason for this may be the restricted resolution power of the Feulgen-Fast-Green staining that is routinely used. Here w...

it has been proposed that organic nitrates such as glyceryl trinitrate (gtn), used in the treatment of cardiovascular diseases, act by producing nitric oxide (no). however, the biochemical pathway for no formation from gtn is not well understood. in the present study, we showed that nitrate formation from gtn, by isolated rat hepatocytes, was inhibited about 50% when cellular glutathione was de...

The effects and interaction between cAMP-analogue dibutyryl-cAMP and calmodulin antagonists were investigated on de novo synthesis and secretion of lipids in cultures of hepatoma McArdle-RH7777 cells and normal rat hepatocytes. Dibutyryl cAMP caused a significant decrease in the secretion of de novo synthesized triacyl [3H] glycerol in both cultures of McArdle cells and rat hepatocytes. The ...
