Abstract Purpose Artificial organs might serve as alternative solutions for whole organ transplantation. Decellularization of a liver provides non-immunogenic matrix with the advantage three afferent systems, portal vein, hepatic artery and bile duct. This study aims to evaluate recellularization rat livers islets Langerhans via duct vein comparison different perfusion routes. Methods Rat were ...

thyrotoxicosis is a condition in which tissues are stimulated by increased secretion of thyroid hormone. the most common cause is diffuse toxic goiter and toxic multi-nodular goiter. for more reviews on this disease, the effects of hyperthyroidism on liver enzyme levels were studied. a total of 30 adult male wistar rats weighing about 190 g were purchased from the pasteur institute of iran. in ...

Lysine-epsilon-C(14)-labeled plasma proteins produced by the normal rat and the isolated perfused rat liver have been fractionated by preparative zone electrophoresis. The isolated perfused liver incorporates lysine-epsilon-C(14) into the plasma albumin, alpha globulin, and beta globulin (including fibrinogen) fractions. No significant C(14) incorporation into the trichloracetic acid-precipitab...

Methods were developed for the assay of hydroxymethylglutaryl-CoA reductase (NADPH) activity in microsomes from rat leukocytes. The activity in freshly isolated leukocytes is low compared to rat liver but can be assayed reliably. The patterns of response of leukocyte reductase in the assay to variation in substrate concentration, protein concentration, and time mimic those of rat liver reductas...

Mesenchymal stem cells derived from bone marrow or several fetal tissues can be expanded and differentiated into other cell lines. The fetal liver is the source of early hematopoietic cells and also, as a fetal tissue, may be considered as a source of pluripotent stem cells. The differentiation potential of fetal rat liver cells have been examined. Freshly isolated liver cells from 14-d fetuses...

The effect of thiamine and its various derivatives on the respiratory control of rat liver mitochondria was examined. Except TDP all other thiamine derivatives tested were shown to damage mitochondrial respiration. In these experiments DCET and T A TD are shown to be strong inhibitors. It was noted that thiamine and its derivatives except TDP have aldehyde group in their chemical structure. Bec...

introduction: in the current study, protective effect of natural honey applied during ischemia/reperfusion (i/r) was studied on infarct size in ischemic heartheart. methods: ischemic hearthearts (n=8 per group) were mounted on a langendorff apparatus at constant pressure then subjected to 30 min regional ischemia followed by 120 min reperfusion. in control group, the hearts were perfused by a m...

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...

The metabolism of dipropyl disulfide (DPDS), an Allium sulfur compound, was investigated in rat liver cell subfractions and in an isolated perfused rat liver. DPDS is oxidized to dipropyl thiosulfinate (DPDSO) by rat microsomes. The contribution of cytochrome P450 enzymes (CYPs) or flavin-containing monooxygenases (FMO) to the formation of DPDSO from its precursor was investigated. In rat micro...
