conclusions hepatocyte isolation can be performed as the main and initial step for cell transplantation from unused/rejected liver. it is the first experience in iran. results highly quality hepatocytes with high viability and low contamination were isolated. the mean viability was 71.8% ± 21.7. in the first 4 cases microbial contamination by staphylococci, diphtheroid and klebsiella was detect...
Rat serum very low density lipoprotein (VLDL) inhibits initiation of DNA synthesis in fetal rat hepatocyte cultures; cells engaged in synthesizing DNA resist inhibition. VLDL action is specific and apparently blocks prereplicative protein synthesis. These and other results, from studies of altered blood VLDL levels and [3H] thymidine incorporation into isolated liver nuclei in 70% hepatectomize...
Crocin, the main constituent of saffron (Crocus sativus L.), is a natural carotenoid which is known for its antioxidant activity. Liver as the organ that metabolizes many chemicals is one of the first position that is at risk of environmental pollutants. It is clear that compounds that exhibit antioxidant properties, scavenging of free radicals and inhibition of lipid peroxidation are expected ...
The genotoxicity of benzo(a)pyrene (BP) was investigated in combined cultures of rat hepatocytes and human diploid fibroblasts. Freshly isolated rat hepatocytes were shown to activate BP to a species which bound to and damaged hepatocyte and fibroblast DNA. A significant increase in the hypoxanthine-guanine phosphoribosyltransferase mutation frequency was induced when 10 to 100 microM BP was ad...
objective: ganoderma lucidum (g. lucidum) has been suggested to increase serum insulin level.this study was undertaken to investigateits direct effect on the islets of langerhans. material and methods: male albino wistar rats were anesthetized and the islets were isolated after digestion of the pancreas with collagenase. the islets were incubated for 60 min in krebs bicarbonate buffer containin...
The newly isolated peptide PHI provoked a dose-dependent stimulation of glycogenolysis and gluconeogenesis in isolated rat hepatocytes; at 1 microM-PHI, both processes were increased 1.6-fold as compared with basal values. These PHI-mediated effects were accompanied by the activation of glycogen phosphorylase and the inactivation of pyruvate kinase. PHI (1 microM) also caused a 2-fold increase ...
objective(s) this study aimed to investigate and to compare the effects of nifedipine and amlodipine, dihydropyridine (dhp) calcium channel blockers (ccbs) on perfusion pressure of isolated perfused rat kidney. materials and methods following the establishment of renal perfusion with a constant baseline pressure of 85-95 mmhg, the renal vasculature was constricted by phenylephrine (pe) injectio...
The purpose of this work was to analyze the contribution of the mitochondria to the optical properties, i.e., light absorption and scattering, of the blood-free rat liver. Firstly, a theoretical model of the reduced scattering coefficient of the liver was performed by using the Mie theory, the Rayleigh-Debye-Gans approximation, and the electron microscopy descriptions of the liver ultrastructur...
