Recordings of renal and splanchnic sympathetic nervous activity in normotensive and spontaneously hypertensive rats.
1. Recordings have been obtained from single sympathetic fibres to the left kidney in anaesthetized adult spontaneously hypertensive (SH) rats and Wistar-Kyoto normotensive (WK) rats. 2. Under control conditions SH rats had a mean sympathetic activity of 3.3 +/- SE 0.45 Hz and WK rats 1.6 +/- 0.23 Hz. During noradrenaline infusion single fibre discharge decreased gradually to low levels in both...
متن کاملRegulation of blood pressure by sympathetic nerve fibers and adrenal medulla in normotensive and hypertensive rats.
The respective roles of the sympathetic nerve fibers and adrenal medulla in the regulation of blood pressure and heart rate were studied in normotensive and hypertensive rats. Chemical sympathectomy alone, by treatment with 6OH-DA, or bilateral adrenalectomy reduced blood pressure only slightly in normotensive animals. In animals made hypertensive with deoxycorticosterone (DOCA) and saline, eac...
متن کاملComparison of sympathetic nerve activity in normotensive and hypertensive subjects.
A microneurographic technique was used to record multiunit sympathetic activity in skin and muscle nerves of 24 healthy subjects and 21 hypertensive subjects. In both groups, the sympathetic activity recorded during rest appeared in bursts following one of two highly different temporal patterns—one characteristic for muscle nerves and the other characteristic for skin nerves. Muscle nerve sympa...
متن کاملNeuropeptide Y and sympathetic nervous system in blood pressure regulation.
Neuropeptide Y and Sympathetic Nervous System in Blood Pressure Regulation To the Editor: We read with great interest the recent article by Dr Michalkiewicz and his colleagues1 dealing with a possible link between neuropeptide Y (NPY) and sympathetic nervous system in the NPY-transgenic rats. The results of their presented study demonstrated that overexpression of endogenous NPY in the transgen...
متن کاملPreeclampsia Blood Pressure Change in Normotensive, Gestational Hypertensive, Preeclamptic, and Essential Hypertensive Pregnancies
We compared patterns of blood pressure (BP) change among normotensive women, women who developed gestational hypertension or preeclampsia, and women who had essential hypertension to examine how distinct these conditions are and whether rates of BP change may help to identify women at risk for hypertensive disorders. We used antenatal clinic BP measurements (median, 14 per woman) of 13016 women...
