Endothelin is a powerful vasoconstrictor that may be partly responsible for the increases in venous and arterial tone characteristic of heart failure. The release of endothelin from endothelial cells in culture is stimulated by angiotensin II. We investigated the relationship between plasma concentrations of immuno reactive endothelin-1 and angiotensin II(More)
AIM To investigate whether aerobic fitness is associated with skin microvascular function in healthy adults with an increased risk of developing Type 2 diabetes. METHODS Twenty-seven healthy normal glucose-tolerant humans with either a previous diagnosis of gestational diabetes or having two parents with Type 2 diabetes and 27 healthy adults who had no(More)
Study of 87 patients (53 adults, 23 males; 34 children, 18 males) with congenital rubella revealed an increased incidence of several HL-A antigens, including HL-A5, HL-A1, HL-A3 and HL-A8, the frequency of HL-A1 being raised because of the statistically significant increase of this antigen in the adult female subjects compared with normal controls.(More)
BACKGROUND Calcitonin gene-related peptide (CGRP) is a potent dilator of normal epicardial coronary vessels in humans, but its effects on myocardial blood flow and atheromatous coronary vessel diameter are unknown. METHODS AND RESULTS Seven patients were entered for study of the effects of CGRP on coronary blood flow and 13 for the comparison of its(More)

Eight patients with isolated PCL-deficient knees were examined to determine whether or not the proprioceptive function of the knee joint was affected or impaired by the previous tear of the PCL. The patients were examined for perception of(More)
One hundred forty-six patients with recent acute myocardial infarction were grouped at random into those treated with tocainide, an oral analogue of lignocaine, or placebo and followed up for 6 months. In addition to standard investigations, a 24-hour ambulatory taped ECG recording was obtained prior to randomization and thereafter at 2, 8, 16, and 24 hours(More)
The successful surgical treatment of an aneurysm of the left main pulmonary artery is reported. It appears that, after ligation of the main pulmonary artery, it is desirable not to remove the lung but preserve it as a space occupying organ which will retain some function. Literature on the subject of pulmonary aneurysms is reviewed. P ULMONARY ARTERY(More)
