Why the study?
Does excess salt ingestion increase blood pressure in DOCA-treated rats compared to sham rats?
Population
Rats 2 weeks after implantation of subcutaneous silicone pellets containing DOCA (65 mg) or no drug (sham)
Comparison
Excess salt ingestion for 2 weeks vs Sham rats receiving the same excess salt ingestion
Design
Preclinical
Follow-up
2 weeks

Rapid BP rise after salt in DOCA rats but not sham; leaves open translation to human salt-sensitive hypertension.
Does excess salt ingestion increase blood pressure in DOCA-treated rats compared to sham rats?
The hypertension induced by combined DOCA and salt in rats exhibits multiple phases, involves hypertonicity-induced vasopressin and nonvasopressin mechanisms, and can be rapidly reversed by water ingestion.
Brooks et al. (2006) studied this question.
