Task: Question Generation
Input (English): Uremic toxins have been shown to promote glomerular hypertrophy. The present study was performed to elucidate the relation between uremic toxins and tubulointerstitial changes.', 'Sixty male Sprague-Dawley rats underwent 2/3 nephrectomy (Nx; n = 30) and 4/5 Nx (n = 30). Experiments were initiated 2 weeks after surgery, and were performed over an 8-week period. Half of each group (Nx-A) was administered 1 g/day of an oral carbonaceous adsorbent, AST-120, with pair-feeding, and the other half (Nx-C) served as controls. All rats were sacrificed at week 8 after a clearance study.', 'The shortest diameter of proximal tubules (PTD) and interstitial fibrosis area (IFA) at week 8 in 2/3 Nx-A rats was significantly decreased compared to that in 2/3 Nx-C rats (similar body weights, systolic blood pressures, glomerular filtration rates, and urinary protein excretion levels). The values of PTD and IFA, glomerular filtration rate and urinary protein excretion level at week 8 in 4/5 Nx-A rats were significantly decreased compared to those in 4/5 Nx-C rats (similar body weights and systolic blood pressures).
Output (English): Do uremic toxins adsorbed by AST-120 promote tubular hypertrophy and interstitial fibrosis in nephrectomized rats?
