Role of peritubular capillary forces in the renal action of carbonic anhydrase inhibitor

Role of peritubular capillary forces in the renal action of carbonic anhydrase inhibitor. Micropuncture study was performed in Munich–Wistar rats to assess peritubular capillary Starling forces in renal superficial cortex during suppression of proximal fluid reabsorption by carbonic anhydrase inhibitor. Administration of benzolamide (2 mg/kg/hr, i.v., Group 1, N=7 rats) caused not only reduction in absolute rate of proximal fluid reabsorption (APR, from 26.7 ± 4.0 nl/min to 17.7 ± 3.6, P
