Abstrakt: Increased glomerular capillary pressure (GCP) mediates glomerular damage in hypertension. The efficacy of captopril, an angiotensin converting enzyme (ACE) inhibitor, and captopril-hydrochlorothiazide (captopril-TZ) in lowering GCP and preventing glomerular damage was evaluated in rats with two-kidney, one clip (2K, 1C) Goldblatt hypertension and partial ablation of the unclipped kidney. Thirty days after surgery nine rats received captopril, 11 received captopril-TZ and eight served as untreated control rats. Sixty days later systemic hypertension was associated with increased GCP and severe structural damage in the unclipped kidney of C rats. Captopril lowered arterial pressure (AP), and prevented the rise in GCP and structural lesion. Captopril-TZ decreased AP and GCP to a greater extent, but did not reduce structural damage further. Captopril lowered GCP, preventing structural damage; greater reduction of GCP with captopril-TZ did not provide further protection.
