introduction: in the present study, potential differences between the effects of l-carnitine (lc) and acetyl-lcarnitine (alc) on ischemia/reperfusion (i/r)-induced myocardial infarction size were investigated. methods: male wistar rats were randomly divided into five groups and then anesthetized by sodium pentobarbital. hearts of the animals were removed and quickly mounted on a langendorff app...
imatinib is an orally administered tyrosine kinase inhibitor which inhibits the bcr-abl protein-tyrosine kinase with high selectivity. imatinib is rapidly absorbed from the gut, after oral intake and has an almost absolute bioavailability of 98%. the metabolism of imatinib is mediated by the cytochrome p450 (cyp) isoenzymes in the liver and gut wall. cgp74588 is a major active metabolite of ima...
The elucidation of the effect of extracellular matrices on hepatocellular metabolism is critical to understand the mechanism of functional upregulation. We have developed a system using natural extracellular matrices [Adipogel] for enhanced albumin synthesis of rat hepatocyte cultures for a period of 10 days as compared to collagen sandwich cultures. Primary rat hepatocytes isolated from livers...
There are several differentiation methods for mesenchymal stem cells (MSCs) into hepatocyte-like cell. Investigators reported various hepatic differentiation protocols such as modifying culturing conditions or using various growth factors/cytokines. In this literature review, we compared different MSCs extraction and isolation protocols from Wharton’s jelly (WJ) and explored various MSCs differ...
The mixed-function-oxidase (MFO) activities, ethoxyresorufin and pentoxyphenoxazone O-dealkylase, of cultured Hooded-Lister(HL)-rat hepatocytes declined rapidly during 72 h of culture, whereas in Sprague-Dawley(SD)-rat hepatocytes the MFO activities increased between 24 and 72 h in culture. Cytochrome P-450 content declined at the same rate in both HL- and SD-rat hepatocyte cultures. NADPH:cyto...
the isolated perfused rat liver (iprl) model has been used into toxicology study of rat liver. this model provides an opportunity at evaluation of liver function in an isolated setting. studies showed that cd, in a dose-dependent manner, induced toxic effects in iprl models, and these effects were associated with aminotransferase activity and lipid peroxidation. the aim of this study was to inv...
A growth factor stimulating DNA synthesis of adult rat hepatocytes in primary culture was found in the conditioned medium after culturing nonparenchymal liver cells (NPC). Adding heparin to the NPC cultured medium stimulated the growth-factor secretion from NPC. The growth factor was secreted mainly by Kupffer cells. The partially purified growth factor from the NPC appeared to be related to th...
In the bile acid biosynthetic pathways of humans and the rat, hepatic 3 alpha-hydroxysteroid dehydrogenase (3 alpha-HSDH) catalyzes the stereospecific reduction of the 3-oxo group of bile acid precursors. In addition, 3 alpha-HSDH may serve to shuttle bile acids from sinusoidal to apical (cannalicular) membranes of the rat hepatocyte. The objective of the present study was to define the molecul...
Whole organ engineering and cell-based regenerative medicine approaches are being investigated as potential therapeutic options for end-stage liver failure. However, a major challenge of these strategies is the loss of hepatic specific function after hepatocytes are removed from their native microenvironment. The objective of the present study was to determine if solubilized liver extracellular...
To understand the transport function of drugs across the canalicular membrane of hepatocytes, it would be important to measure concentrations in hepatocytes and bile. However, these concentration gradients are rarely provided. The aim of the study is then to measure these concentrations and define parameters to quantify the canalicular transport of drugs through the multiple resistance associat...
