Diet	n	Serum Na, meq/l	Serum K, meq/l	Urinary Na, meq/ml	Urinary K, meq/ml	Serum Aldosterone, pg/ml
Control K+	4	147.0 ± 0.6	4.3 ± 0.3	0.022 ± 0.001	0.055 ± 0.005	213.8 ± 20
High K+	6	145.6 ± 0.8	4.2 ± 0.2	0.014 ± 0.003	0.277 ± 0.02*	1,097.0 ± 200.1*

Values are means ± SE; n = no. of rats. Rats were fed for 15 days.
