Angiotensin II-induced renal vasoconstriction in genetic hypertension.
Previous studies demonstrate that renovascular responses to angiotensin II (Ang II) are enhanced in spontaneously hypertensive rats (SHRs); however, it is possible that this hyperresponsiveness is mediated by Ang II-induced release of substances from the adrenal gland. Previous studies also show that pertussis toxin normalizes renovascular responses to Ang II in SHRs; however, it is possible th...
متن کاملRenal endothelin in chronic angiotensin II hypertension.
To determine the influence of chronic ANG II infusion on urinary, plasma, and renal tissue levels of immunoreactive endothelin (ET), ANG II (65 ng/min) or saline vehicle was delivered via osmotic minipump in male Sprague-Dawley rats given either a high-salt diet (10% NaCl) or normal-salt diet (0.8% NaCl). High-salt diet alone caused a slight but not statistically significant increase (7 +/- 1%)...
متن کاملRenal injury from angiotensin II-mediated hypertension.
Angiotensin II (Ang II)-mediated hypertension induces vascular smooth muscle cell hypertrophy and hyperplasia in systemic blood vessels, but the effects of Ang II on the intrinsic cell populations within the kidney have been less well characterized. We infused Ang II for 14 days into rats by minipump at doses (200 ng/min) that resulted in moderate hypertension (mean systolic blood pressure 156-...
متن کاملAngiotensin II-induced hypertension in bradykinin B2 receptor knockout mice.
The present study was performed to examine the role of endogenous bradykinin (BK) in the development of angiotensin II (Ang II)-induced hypertension in mice. BK B2receptor knockout (B2R-/-) and wild-type (B2R+/+) mice (22to 26 g) were infused with either saline (SAL) or Ang II (40ng/min) via an osmotic minipump implanted intraperitoneally. On day 12after implantation, there was no difference in...
متن کاملAngiotensin II hypertension is attenuated in interleukin-6 knockout mice.
Plasma levels of IL-6 correlate with high blood pressure under many circumstances, and ANG II has been shown to stimulate IL-6 production from various cell types. This study tested the role of IL-6 in mediating the hypertension caused by high-dose ANG II and a high-salt diet. Male C57BL6 and IL-6 knockout (IL-6 KO) mice were implanted with biotelemetry devices and placed in metabolic cages to m...
