The cardiovascular structural remodelling associated with psychogenic hypertension was investigated in genetically normotensive rats subjected to isolation stress. Male Wistar rats were stressed by intermittent social isolation and compared to control rats living in groups. The stressed rats had higher systolic blood pressures than the control rats(More)
In this study, ornithine decarboxylase, the first and rate-limiting enzyme of the polyamine pathway, was used as a marker of the very early stages of cardiac hypertrophy. Our data show that ornithine decarboxylase is independently regulated by ventricular wall stress and adrenergic receptors, and support the theory that catecholamines have a(More)
UNLABELLED Biochemical mechanisms which control cardiac and vascular response to hypertension are still unclear. Modifications of polyamines (putrescine, spermine, spermidine) may play a role in this phenomenon, since these molecules have been shown of importance in the control of tissue growth. Ornithine Decarboxylase (ODC) catalyses the first and probably(More)
