Characteristic mucosal lesions develop in the small intestine during ischaemia and hypotension. This tissue damage can be further aggravated in the immediate reperfusion phase, presumably secondary to the generation of oxygen free radicals which have been proposed to be generated in this situation through the hypoxanthine-xanthine oxidase system. This was(More)
Regional intestinal ischemia in cats resulted in an accumulation of hypoxanthine within 2 h, the concentration of which rose from 0.062 to 1.131 nmol/mg protein. A similar rise in AMP content (from 0.5 to 3.2 nmol/mg protein) was observed, but not in the ADP level. In parallel, ATP content decreased from 7.5 to 2.8 nmol/mg protein. Reperfusion of the(More)
Bone marrow-derived mesenchymal stem cells (MSCs) are used in stroke treatment despite the poor understanding of its mode of action. The immune suppressive and anti-inflammatory properties of MSCs possibly play important roles in regulating neuroinflammation after stroke. We investigated whether MSCs reduce the inflammatory complement component 3 (C3)(More)
Glucagon like peptide-1 (GLP-1) stimulates glucose-dependent insulin secretion. Dipeptidyl peptidase-4 (DPP-4) inhibitors, which block inactivation of GLP-1, are currently in clinical use for type 2 diabetes mellitus. Recently, GLP-1 has also been reported to have neuroprotective effects in cases of cerebral ischemia. We therefore investigated the(More)
Female rats, treated with allylisopropylacetamide (AIA) showed a marked decrease of hepatic NADH-5 alpha-reductase, NADPH-5 alpha-reductase, NAD+- and NADP+-3 alpha-hydroxysteroid dehydrogenase activities and an increase of the activity of NADH- and NADPH-5 beta-reductase and NAD+ and NADP+-3 beta-hydroxysteroid dehydrogenase. Administration of Sedormid(More)
