title: Unilateral renal disease in the rat. II. Glomerular mesangial uptake of colloidal carbon in unilateral aminonucleoside nephrosis and nephrotoxic serum nephritis.
abstract: Unilateral renal disease was produced in rats by left renal perfusion in situ with the aminonucleoside of puromycin or with nephrotoxic serum. The uptake of colloidal carbon by the glomerular mesangium was increased in kidneys perfused with aminonucleoside or nephrotoxic serum compared to contralateral kidneys. The quantities of carbon within the glomerular mesangium remained increased in aminonucleoside perfused kidneys 14 days later. These studies demonstrate that alterations in glomerular mesangial function in aminonucleoside nephrosis and nephrotoxic serum nephritis are related to renal factors rather than differences in host milieu and may be involved in the pathogenesis of the morphologic lesions seen in chronic proteinuria.
