Key result
Hexamethonium administration reduced hind-limb perfusion pressures of spontaneous hypertensive, chronic renal hypertensive, and control rats to the same average level.
Why the study?
Does hexamethonium administration normalize peripheral resistance in spontaneous and renal hypertensive rats compared to controls?
Population
Rats bred to develop hypertension spontaneously, rats with chronic renal hypertension, and control rats
Comparison
Hexamethonium administration and cross-perfusion… vs Control rats and baseline measurements

Reinforces neurogenic tone in rodent hypertension models; leaves open translation to human therapy.
Does hexamethonium administration normalize peripheral resistance in spontaneous and renal hypertensive rats compared to controls?
The study demonstrates that the increased peripheral resistance in spontaneous and chronic renal hypertensive rats is primarily maintained by neurogenic tone rather than circulating vasoconstrictors.
Laverty et al. (1961) studied Hypertension. Hexamethonium vs. Control rats was evaluated on Hind-limb perfusion pressure and blood pressure. Hexamethonium administration reduced hind-limb perfusion pressures of spontaneous hypertensive, chronic renal hypertensive, and control rats to the same average level.
