Effect of 10−5 M bath ouabain on adult and neonatal proximal straight tubule NaCl transport. Proximal straight tubules were perfused with a high-chloride solution simulating late proximal tubular fluid and bathed in a serumlike albumin solution. After measurements of volume absorption (JV) in the control period, 10−5 M bath ouabain was added to the bathing solution to inhibit active transport.
