The effects of early glycosylation products (Amadori Products, AP) were investigated in male Munich-Wistar rats to establish whether AP play a role in the pathogenesis of glomerular hyperfiltration of early diabetic nephropathy. To mimic such a condition, normal rats were transfused with blood containing in vitro glycated serum (Group GLYC) to achieve plasma levels of Amadori products similar to those measured in rats with streptozotocin-induced diabetes. Rats transfused with normal blood were used as control (Group CON). Glomerular hemodynamics was evaluated in basal condition (B) and during acute hyperglycemia (HG). Blood transfusion did not alter basal hemodynamics. In Group CON, HG determined a rise of single nephron GFR (41.4 +/- 3.2 vs. 32.1 +/- 1.8 nl/min, P less than 0.005), secondary to the increase of afferent effective filtration pressure (EFPa, +19% vs. B, P less than 0.01). Rats of Group GLYC, in B, had values of SNGFR higher than those of Group CON B (46.8 +/- 3 nl/min, P less than 0.05, ANOVA). This increase was mediated by a significant reduction of glomerular afferent arteriole (Ra, -38% vs. Group CON B, P less than 0.05), a rise in hydrostatic gradient pressure in glomerular capillaries (delta P, +17%, P less than 0.05) and of EFPa (+31%, P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
