The perfused rat kidney was used for a study of gluconeogenesis. The kidney was completely isolated and perfused with Krebs-Henseleit bicarbonate buffer containing 5% albumin. Perfusion flow rate and pressure remained stable for 2 to 3 hours, although the glomerular filtration rate diminished with time. The fractional reabsorption of both water and sodium was 0.92 during the 1st hour of perfusi...

Considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (UA), a soluble salt of depleted uranium (DU). We examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (BHT), to prevent UA-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. Beta-glucan (150 nM) and BHT (20 nM) attenuated UA-indu...

We analyzed the expression of plasma glutathione peroxidase (GSHPx-P) messenger RNA (mRNA) in mouse, rat, and human tissues, using a human GSHPx-P cDNA clone as the probe. Unlike the classical cellular glutathione peroxidase (GSHPx-1), GSHPx-P expression appears to be tissue-specific. In the mouse and rat, kidney expresses an mRNA at a high level detected with the human probe. A signal is also ...

background: it has been reported that the chronic oral administration of garlic homogenate protected the rat heart from in vitro ischemic reperfusion injury. however, the biological effects of garlic juice on the heart are expected to be different from oral administration of it. objective: the present study was designed to investigate the effect of garlic juice on the isolated rat heart in isch...

background and objective : sleep deprivation (sd) is caused by a host of reasons and has numerous consequences on cardiac system. in this study, we aimed to assess the preconditioning effects of acute sd on ischemia (is)-induced ventricular arrhythmias in isolated rat hearts. materials and methods : male wistar rats randomly were placed into the four groups: is-group, acute sd group, control gr...

in the current study, effects of acute short term administration of fructose on cardiac arrhythmias and myocardial infarction size following ischemia/reperfusion were investigated in isolated rat heart. the hearts were subjected to 30 min zero flow global ischemia followed by 120 min reperfusion. in the control group, the hearts were perfused by normal drug free krebs-henseleit (k/h) solution t...

objective: foeniculum vulgare seed (f. vulgare) is a herbal plant which is used with phytoestrogene compounds for polycystic ovary syndrome (pcos) treatment. in this research, renoprotective effect of the aqueous extract of foeniculum vulgare (aef) in experimental pcos female rats is studied. materials and methods: forty female rats were randomly divided into five groups. the first group served...

phosphate (cyclic AMP) newly synthesized ruring in vitro incubation of the isolated rat kidney cells with adenine-8-14C. By combined use of the BaSO4 treatment and the onedimensional ascending cellulose thin-layer chromatography with stepwise development by two solvents, newly formed or labeled cyclic AMP (14C-cyclic AMP) could completely be separated from the related radioactive metabolites in...

cDNA clone for general acyl CoA dehydrogenase (GAD) was isolated from a rat liver cDNA expression library in lambda gt11 using anti-pig kidney GAD antibody. Size of the isolated cDNA was estimated to be 1.5-1.6 kb. By immunological analysis of fusion protein and epitope selection, the cDNA clone was identified as that containing the GAD gene. Partial amino acid sequence deduced from nucleotide ...
