OBJECTIVE The present study was undertaken to investigate the effect of dietary magnesium (Mg) deficiency on plasma levels of parathyroid hormone (PTH) and calcitonin (CT), and the changes in tissue calcium (Ca) and phosphorus (P) content. METHODS Wistar rats were fed an Mg-deficient diet. Plasma levels of PTH and CT, and Ca and P content in plasma, whole(More)
INTRODUCTION Critically ill patients suffer from oxidative stress caused by reactive oxygen species (ROS) and reactive nitrogen species (RNS). Although ROS/RNS are constantly produced under normal circumstances, critical illness can drastically increase their production. These patients have reduced plasma and intracellular levels of antioxidants and free(More)
The effect of intracerebroventricular or intraperitoneal administration of cannabinoid receptor agonist WIN 55,212-2 or inverse agonist AM 251 on food intake and extracellular levels of serotonin and acetic acid 5-hydroxy-indol from presatiated rats was studied. Compared to the vehicle-injected control, the intracerebroventricular administration of WIN(More)

Cytosolic calcium signals evoked by the sulphydryl-group-oxidising agent, thimerosal, have been investigated in acutely isolated pancreatic acinar cells. Two techniques were employed for the assessment of the cytosolic free-calcium concentration ([Ca2+]i): measurement of calcium-dependent chloride and non-specific cation currents (whole-cell patch-clamp(More)
