Phencyclidine (PCP), a noncompetitive N-methyl-D-aspartate receptor antagonist, induces psychotomimetic effects in humans and animals. Administration of PCP to rodents is used as a preclinical model for schizophrenia; however, the molecular mechanisms underlying the symptoms remain largely unknown. Acute PCP treatment rapidly induces behavioral and(More)
In rats several circadian rhythms such as heart rate, body temperature, and locomotor activity are known. Several authors found a loss of day-night-rhythm (locomotor activity, EEG) after portacaval shunting (PCA). The aim of this study was to evaluate whether muscle PO2 oscillations are circadian and whether they are altered after time-limited(More)
The influence of a hyperdynamic syndrome caused by PCA on PO2 distribution in skeletal muscle of rats during the initial phase of muscle activity was examined. Rhythmical muscle contraction of the m. biceps femoris was induced by direct electrical stimulation. Tissue PO2 of the contracting muscle was recorded continuously from the start of the 210 s-long(More)
