Serum and urine electrolyte concentrations. Serum (A) and urine (B) samples were taken from 12- to 18-hr-old pups and were analyzed for Na+, K+, and Cl−. Numbers of animals in each serum group were 15 +/+, 8 +/−, and 6 −/−. Numbers of animals in each urine group were 15 +/+, 8 +/−, and 10 −/−. Data are mean ± SEM. Asterisk indicates P < 0.05 compared with +/+ animals.
