Angiotensinergic stimulation of vascular endothelium in mice causes hypotension, bradycardia, and attenuated angiotensin response.

It is not clear whether endothelial cell (EC) activation by the hormone angiotensin II (Ang II) modulates contraction of vascular smooth muscle cells (VSMCs) in the vasculature and whether impairment of this regulation in vivo contributes to hypertension. Delineation of the actions of Ang II through the type 1 receptor (AT1R) on ECs in the blood vessels has been a challenging problem because of...

Endothelial cell-specific knockout of connexin 43 causes hypotension and bradycardia in mice.

Connexin 43 (Cx43) is a protein expressed in a variety of mammalian tissues. However, the lack of specific blockers and the absence of known genetic mutants have hampered the investigation of the function of this protein. Cx43-null mice die shortly after birth, thus preventing functional studies in vivo. Here, we report the generation and characterization of a vascular endothelial cell-specific...

Management of Hypotension and Bradycardia Caused by Spinal Cord Injury. The Usefulness of Midodrine and Methylxanthines

Spinal cord injury is a devastating chronic condition resulting in temporary or permanent motor,sensory or autonomic dysfunction of the cord. The manifestation of spinal cord injury based onthe severity and involved areas could be different. Numerous studies have demonstrated thatbradycardia, hypotension, and orthostatic hypotension are present insignificant number ofpat...

Overexpression of eNOS in NTS causes hypotension and bradycardia in vivo.

The role of nitric oxide (NO) in the brain in the control of blood pressure and the sympathetic nervous system is debated. This study examined the effect of overexpression of endothelial NO synthase (eNOS) in the nucleus tractus solitarii (NTS) on blood pressure in conscious rats. Adenovirus vectors encoding either eNOS (AdeNOS) or ss-galactosidase were transfected into the NTS in vivo. In the ...

Severe bradycardia and prolonged hypotension in ciguatera.

Ciguatera results when ciguatoxin-contaminated coral reef fish from tropical or subtropical waters are consumed. The clinical features that present in affected persons are mainly gastrointestinal, neurological, general, and much less commonly, cardiovascular. We report the case of a 50-year-old man who developed the characteristic combination of acute gastrointestinal and neurological symptoms ...
