Key result
Peripheral venous infusion of NaCl significantly decreased plasma renin activity from 28.3 to 13.3 ng/ml per h (P<0.01) in NaCl-deprived rats, indicating renin inhibition depends on chloride.
Why the study?
Does chloride infusion reduce plasma renin activity in NaCl-deprived rats?
Does chloride infusion reduce plasma renin activity in NaCl-deprived rats?
p-value: p=<0.01
Acute inhibition of renin by sodium is dependent on an intrarenal effect of chloride, likely related to absorptive chloride transport in the thick ascending limb of the loop of Henle.

Chloride-dependent renin suppression via tubular reabsorption in rats; leaves open translation to human cardiorenal disease.
Kirchner et al. (1978) studied NaCl-deprived rats. Peripheral venous infusion of NaCl vs. Controls and animals infused with other sodium salts was evaluated on Plasma renin activity (PRA) (p=<0.01). Peripheral venous infusion of NaCl significantly decreased plasma renin activity from 28.3 to 13.3 ng/ml per h (P<0.01) in NaCl-deprived rats, indicating renin inhibition depends on chloride.
