Depression is frequently encountered in Parkinson's disease and was seen to occur in 14 of 26 patients studied. The levels of 5-hydroxyindoleacetic acid (5-HIAA), the main metabolite of serotonin (5-HT), in CSF samples of the patients were significantly lower than in those of controls. However, within the group of patients the levels of 5-HIAA in CSF(More)
The effects of the following drugs: nimodipine (1 mg/kg b. w., i. p.), 2-amino-5-phosphonovaleric acid (4mg/kg b.w., i.p.) and propentofylline (25mg/kg b.w., i.p.), administered (alone or in combination) at the end of 15 min bilateral ischemia in gerbils were evaluated on mitochondrial superoxide dismutase (SOD), glutathione reductase (GR), glucose-6(More)
The separately cultured smooth muscle and endothelial cells derived from dissociated cerebral microvessels are characterized by high content of glycogen. Norepinephrine induces glycogenolysis while 5-hydroxytryptamine stimulates glycogenesis in both cell types. The endogenous glucose of the endothelium but not that of the smooth muscle serves as a direct(More)
The aim of this study was to evaluate the substrate (ATP) kinetics of erythrocyte membrane Na, K-ATPase in children with borderline or essential hypertension. Although the activity of Na, K-ATPase in the presence of in vivo concentrations of ATP was not significantly altered, kinetic studies showed an obvious inhibition of enzyme activity in the erythrocyte(More)
The concentration of prostaglandin F2 alpha (PGF2 alpha) was measured in cerebrospinal fluid (CSF) of 50 patients with recent stroke divided into three groups in respect to the time (up to 24 h) that expired between cerebrovascular insult and CSF sampling. 10 of the additionally studied persons were neurologically normal (control group). None of the(More)
The post-ischemic effects on cerebral cortex and basal ganglia monoamine levels and monoamine oxidase (MAO A and B) and catechol-O-methyl transferase (COMT) activities were evaluated in Mongolian gerbils (Meriones unguiculatus) subjected to bilateral common carotid arteries occlusion for 15 min and reflow for 7 days. Disorders of monoamine metabolism was(More)
