Why the study?
Does injection of kynurenic acid into the RVLM reduce arterial pressure in spontaneously hypertensive rats compared to normotensive rats?
Population
Spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY), anesthetized with chloralose
Comparison
Bilateral injection of kynurenic acid, an… vs Wistar-Kyoto rats receiving the same injection

RVLM kynurenic acid lowers pressure selectively in SHR; hypothesis-generating for disrupted EAA balance in hypertension.
Does injection of kynurenic acid into the RVLM reduce arterial pressure in spontaneously hypertensive rats compared to normotensive rats?
The balance of excitatory and inhibitory influences on RVLM vasomotor neurons driven by tonically active EAA-mediated inputs is disrupted in spontaneously hypertensive rats and may contribute to hypertension.
