Motor activity during the first 5 min in a motility meter was measured in mice given 0.025-3.2 mg/kg of the dopamine and noradrenaline receptor agonists apomorphine and clonidine, respectively. The accumulation of Dopa, as induced by the inhibitor of aromatic amino acid decarboxylase, NSD 1015, was measured in parallel in two dopamine-rich regions, i.e. the(More)
BACKGROUND Partial correction of renal anaemia with erythropoietin improves quality of life (QoL). We aimed to examine if normalization of haemoglobin with epoetin alfa in pre-dialysis and dialysis patients further improves QoL and is safe. METHODS 416 Scandinavian patients with renal anaemia [pre-dialysis, haemodialysis (HD) and peritoneal dialysis(More)
OBJECTIVES Impaired arterial baroreflex sensitivity (BRS) has been associated with cardiac mortality and non-fatal cardiac arrests after a myocardial infarction. Patients with chronic renal failure (CRF) have a poor prognosis because of cardiovascular diseases, and sudden death is common. The aim of this study was to assess whether BRS or the baroreflex(More)
BACKGROUND Impaired arterial baroreflex function has been associated with an increased risk of ventricular arrhythmia and sudden death. This has also been suggested for patients with chronic renal failure (CRF) who are at high risk for cardiovascular morbidity. The aim of this study was to investigate the arterial baroreflex function in CRF patients with(More)
Accidental venous needle dislodgement during hemodialysis may cause serious bleeding including a sometimes fatal outcome. The venous pressure gauge of the dialysis monitor does not react when dislodgement occurs. A sensor patch put as an adhesive over the venous needle puncture site connected to an alarm unit by an optic fiber has been clinically tested in(More)
Administration of 0.025–0.1 mg/kg of apomorphine i.p. to mice produced a dose-dependent locomotor depression. Haloperidol, 0.025 mg/kg, produced locomotor stimulation, whereas 0.1 mg/kg caused locomotor depression. Pretreatment with haloperidol also reversed the depression caused by apomorphine. The functional antagonism is discussed in terms of a possible(More)
Patients with CRF (chronic renal failure) are at increased risk of cardiovascular diseases, and 60% of cardiovascular mortality in CRF is attributed to sudden death. Various abnormalities in myocardial repolarization are associated with the risk of ventricular arrhythmia. The aim of this study was to evaluate an index of temporal myocardial repolarization(More)
During a 21-month period, the prognosis in all patients admitted to a hospital ward from the emergency room with suspected acute myocardial infarction (AMI) was prospectively recorded and related to the time between onset of symptoms and arrival in hospital. They were classified as early arrivers (less than or equal to 2 h), intermediate arrivers (2-8 h)(More)
DESIGN AND SUBJECTS Several studies suggest neuroendocrine abnormalities in, particularly, abdominal, central obesity in humans, a condition with high morbidity and mortality. Therefore the concentrations of neuropeptides and catecholamines in cerebrospinal fluid (CSF) were analysed in 48 obese women, subdivided into groups with central, abdominal and(More)
The effects of various pretreatment schedules with L-thyroxine (T4) on endogenous brain concentrations of catecholamines (CA) and 5-hydroxy-tryptamine (5-HT) as well as their respective synthesis ratesin vivo and the sensitivity of CA-and 5-HT receptors, respectively, were investigated. None of the T4 pretreatments had any significant effect on the brain(More)
