1 The amount of tritium released upon transmural stimulation of the isolated vas of the rat incubated with [(3)H]-Delta(1)-tetrahydrocannabinol (THC) (2.8 muM) was significantly greater than the non-stimulated overflow.2 There was no difference between non-stimulated overflow and the effect of transmural stimulation of vasa equilibrated with(More)
1. Rat isolated hearts perfused with delta 1-THC (0.5 micrograms/ml) showed a reduction in the rate of beating which was not altered by pretreatment with propranolol (2 micrograms/ml), atropine (4 micrograms/ml) or hexamethonium (4 micrograms/ml). 2. Propranolol (2 micrograms/ml) also caused a decrease in the rate of beating, which was not affected by(More)
Forty-eight isolated rat hearts were perfused with Krebs solution and with [(3)H]-(-)-noradrenaline ([(3)H]-NA) containing 4.5 nCi/ml in 50 ng/ml, as described by Iversen (1963). To groups of six, cocaine was added to [(3)H]-NA in concentrations of 400 nM, 2 and 10 muM. To the rest Tween 80, 25 mug/ml was added to [(3)H]-NA and in three groups Delta(1)-THC(More)
The isolated rat heart perfused with washed platelets was used as a model to examine platelet-vessel wall interactions. Release of prostacyclin and thromboxane A2 was measured, using a cascade of smooth muscle bioassay tissues or radioimmunoassays of the stable hydration products. In hearts perfused with rabbit or human platelets, injection of sodium(More)
The inhibitory activity of urine on calcium oxalate crystallization was measured as an inhibitory index using a gel model modified from Schneider et al. [8]. Urine samples from 36 recurrent stone formers and 21 controls in 3 separate periods (morning, afternoon and evening) were tested. Mean inhibitory indices of >0 were observed among normal controls in(More)
1. In anaesthetized rats, intravenous administration of cannabis extract (10 mg/kg), Delta(1)-tetrahydrocannabinol (THC) (0.5 mg/kg) and Delta(6)-THC (0.5 mg/kg) caused a reduction in systemic blood pressure, pulse rate and respiratory rate.2. Neither cannabinol (1 mg/kg, i.v.) nor cannabidiol (1 mg/kg, i.v.) had any observed effects on the cardiovascular(More)
1. Cardiovascular reflexes to intravenous adrenaline and histamine and to carotid occlusion were studied in the renal vasculature, and direct effects of noradrenaline and clinidoine were compared in renal and hindlimb vascular beds in anaesthetized cats. 2. Unlike its reported effects on cardiovascular reflexes in the hindlimbs, clonidine depressed all(More)
Despite improved biochemical recurrence-free survival rates by the use of immediate adjuvant radiotherapy (RT) in patients with locally advanced prostate cancer, disagreement about the need and timing of RT remains. From 2005–2009, 94 patients presenting with a stage pT3a N0 and microscopic positive resection margin were retrospectively analyzed after(More)
