1. Six well-trained cyclists and six untrained subjects were studied during and immediately after four successive 7 min periods of exercise at 30, 45, 60 and 75% of their maximal work capacity. 2. Venous blood samples were taken at rest, at the end of each exercise period and 5 min following the end of exercise, for estimation of metabolites in blood and(More)
To characterize steady-state indinavir pharmacokinetics in cerebrospinal fluid and plasma, 8 adults infected with human immunodeficiency virus underwent intensive cerebrospinal fluid sampling while receiving indinavir (800 mg every 8 hours) plus nucleoside reverse transcriptase inhibitors. Nine and 11 serial cerebrospinal fluid and plasma samples,(More)
Autonomic function was tested in healthy control subjects and 20 chronic alcoholic patients with varying degrees of alcohol-related peripheral and central neurological damage. The alcoholics were divided into two groups according to the severity of their symptoms and signs. The alcoholic subjects had no postural hypotension. However, heart-rate responses to(More)
The growth hormone (hGH) and prolactin (hPRL) response to insulin induced hypoglycaemia was studied in six alcoholics on two occasions before and after treatment with a single intramuscular injection of fluphenazine (Modecate). On both occasions blood samples were taken at intervals before and after the intravenous injection of soluble insulin (0.1 u/kg(More)
1. To investigate the stimulus to the cardiovascular and respiratory systems during isometric exercise, two patients with sensory neuropathies affecting forearm afferent nerves were studied and their circulatory and respiratory responses compared with those of normal subjects. The contribution of pain to the cardiorespiratory changes was also investigated(More)
Thirty-three epileptic patients were randomly divided into two treatment groups. One group of 18 patients was given sodium valproate; the other 15 patients were given phenytoin. Periods of treatment ranged from 9 t0 48 months (mean, 30 months). Any patient who developed a seizure while on the first drug was changed to the other drug, provided the serum(More)
The growth hormone (hGH) and prolactin (hPRL) responses to oral bromocriptine were studied in two groups of patients with Huntington's chorea and in seven healthy control subjects. The patients included six patients who had previously been treated with phenothiazines and six patients who had not received phenothiazine treatment. All medication was stopped(More)
