Features of intracellular calcium distribution in the adipose tissue of spontaneously hypertensive rats (SHR) 总被引:3,自引:0,他引:3
The in vitro study of the kinetics of 45Ca efflux from adipose tissue of rats reveals 3 pools of exchangeable calcium. Calcium content in the intracellular pools of adipose tissue of spontaneously hypertensive rats is increased as compared to that in normotensive controls. 相似文献

Summary Increased basal TSH levels and an enhanced response to cold-exposure were apparent in the SHR accustomed to +30°C, whereas goitres and an increased amount of the anterior pituitary TSH were measured in SHR kept at +20°C.These studies were supported by grants from the Academy of Finland and Orion Pharmaceuticals Company, Helsinki. The technical help of Mrs Anneli v. Behr is greatly acknowleged. 相似文献

Zusammenfassung Nachweis, dass in Ratten mit genetischem Hochdruck und normalem Herzrhythmus Verdickungen des Endotheliums im Karotissinus und im Aortabogen beobachtet werden. Eine Hypertrophie der Gefässmuskulatur war nachweisbar, was zu einer Abschwächung des Drucksignals zur Stelle der Pressorezeptoren führte. Diese dürften teilweise verantwortlich sein für die Verschiebung der Pressorezeptor-Steuerung bei genetisch hypertensiven Ratten.

Summary In normotensive Wistar rats intracerebroventricular (i.c.v.) injection of 30 mU of lysine8-vasopressin enhances significantly the cardiovagal reflex bradycardia induced by a blood pressure rise. This effect is absent
in spontaneously hypertensive rats (SHR) of the Okamoto strain. 相似文献

Dopamine-beta-hydroxylase (DBH) activity was higher in the serum, the mesenteric artery and the cerebral cortex of 4-week-old stroke-prone spontaneously hypertensive rats (SHRSP), and lower in the nucleus tractus solitarii than it was in spontaneously hypertensive rats (SHR). 相似文献

Summary Incorporation of32P into di- and triphosphoinositides of erythrocytes from 1-month-old spontaneously hypertensive rats was lower, and diphosphoinositide content higher, than in controls. During development of hypertension these initial differences decreased and were even reversed. 相似文献

Summary Monoamine oxidase (MAO) activity was assayed both in central and peripheral blood vessels of spontaneously hypertensive rats (SHR) and age-matched normotensive Wistar Kyoto rats (WKR). The activity of MAO in the brain and peripheral vasculature was essentially the same in both SHR and WKR. It can therefore be concluded that central and peripheral vascular MAO activity is not altered in the genetically hypertensive animals. 相似文献

Summary The delay in blood pressure increase observed in spontaneously hypertensive rats following bilateral renal denervation appeared to be due to a temporary reduction of the renal catecholamines content.This work was supported by grants from the Institut National de la Santé et de la Recherche Médicale (ATP 32-76-64, and AU 79-35) and from the Fonds National Suisse de la Recherche Scientifique (3.033.76) 相似文献

Blood pressure and impairment of endothelium-dependent relaxation in spontaneously hypertensive rats
Summary Correlation between hypertension and impairment of endothelium-dependent relaxation was demonstrated using aortae from certain strains of rats with various levels of spontaneous hypertension. It was also observed that the impairment of endothelium-dependent relaxation is the secondary change due to hypertension, and the level and duration of hypertension is the determinant factor of the impairment. 相似文献

Lower limit of cerebral autoregulation in normotensive and spontaneously hypertensive rats 总被引:3,自引:0,他引:3
Summary Cerebral autoregulation was examined in NTR and SHR. The lower blood pressure limit of autoregulation being 95 mm Hg in SHR was shifted upwards from 62 mm Hg in NTR. 相似文献

Cerebral blood flow (CBF) was measured and cerebrovascular resistance (CVR) was calculated in anesthetized spontaneously hypertensive rats (SHR) and normotensive rats (NR) following the administration of incremental dosages of i.v. flunarizine or papaverine. CBF and CVR changes following papaverine were the same in both groups of rats irrespective of the dose of the drug. The effect of flunarizine was much more pronounced in SHR than in NR. The results point out the greater dependency of basal cerebrovascular tone in SHR upon Ca2+ influx into vascular smooth muscle cells. 相似文献
