1 This study aimed (1) to measure the whole blood to plasma (WB:P) and red blood cell to plasma (RBC:P) concentration ratios of propranolol in healthy volunteers and two types of patients, and (2) to compare the concentration ratios of the lipophilic drug propranolol with moderately lipophilic pindolol and hydrophilic atenolol. 2 There was no significant(More)
1. To study potassium transport in hypokalaemic periodic paralysis in a model of striated muscle cells, we measured specific [3H]ouabain binding (the number of sodium-potassium pumps), sodium-potassium-pump-mediated (ouabain-sensitive) 86Rb+ influx and sodium-potassium-pump-independent (ouabain-resistant) 86Rb+ influx in lymphocytes in vitro. 2. The(More)
We have studied the specific binding of [3H]-ouabain to intact mononuclear leucocytes (82% lymphocytes) and polymorphonuclear leucocytes. In both types of cells [3H]-ouabain binding was saturable, confined to a single site of high affinity, slow to reach equilibrium, slow to reverse, temperature-dependent, competitively antagonized by potassium, and(More)
To test the hypothesis that there is an abnormal serum insulin response to a carbohydrate load in thyrotoxic hypokalaemic periodic paralysis (THPP), 18 men with THPP and 15 with uncomplicated thyrotoxicosis were studied during an oral glucose tolerance test. The THPP group had significantly higher fasting insulin concentrations (27.6 [3.6] vs 13.4 [1.8](More)
1 The effects of beta-adrenoceptor antagonists given in single doses by oral or intravenous routes were examined in two double-blind controlled studies performed in healthy volunteers. Heart rate and peak expiratory flow rate (PEFR) were measured at rest and during standardized exercise. 2 Propranolol 80 mg and metoprolol 100 mg orally tended to reduce, and(More)
1. In the isolated perfused liver from 48h-starved rats, glycogen synthesis was followed by sequential sampling of the two major lobes. 2. The fastest observed rates of glycogen deposition (0.68-0.82mumol of glucose/min per g fresh liver) were obtained in the left lateral lobe, when glucose in the medium was 25-30mm and when gluconeogenic substrates were(More)
1 The effects of beta-adrenoceptor antagonists given intravenously in single doses were examined in a double-blind, placebo controlled study performed in six healthy volunteers. Heart rate and peak expiratory flow rate (PEFR) were measured at rest and during standardised exercise. 2 Atenolol 0.2 mg/kg, betaxolol 0.15 mg/kg, practolol 1 mg/kg and propranolol(More)
The factors making for therapeutic engagement were examined in a series of 50 schoolchildren who had deliberately poisoned themselves. Of these 28 kept an appointment for psychiatric treatment: they were characterised by high levels of psychological symptoms, especially those of depression. The kind of treatment offered was not predictive, but parental(More)
We have measured specific [3H]ouabain binding and ouabain sensitive 86rubidium influx in intact human lymphocytes incubated for up to 7 days in media containing different concentrations of fetal calf serum and human serum. Incubation for periods of up to 7 days with fetal calf serum and human serum produced increases in both specific [3H]ouabain binding and(More)
