Female Munich-Wistar rats received hexadimethrine (HDM) i.v. until the onset of proteinuria (PEAK)--a period of not more than 30 min. There were four experimental groups: C (control), H (HDM only), HH (HDM and heparin), and HHD (identical to HH but with dextran clearances measured). Rats in groups HH and HHD received a heparin bolus after the PEAK period, whereas rats in group H did not. HDM led to dramatic increases in both albumin and IgG excretion. Glomerular filtration rate and renal plasma flow rate were reduced by 30 to 50% after HDM infusion. Neutral dextran clearances for radii greater than 30 A were elevated during the PEAK period, and, concurrently, there was extensive intraglomerular microthrombosis, obliteration of foot processes, and disruption of filtration slit diaphragms. One hour later, glomerular filtration rate, renal plasma flow rate, dextran clearances, and proteinuria returned to baseline in groups HH and HHD but not in group H. Recovery in heparin-treated rats was associated with reversal of HDM-associated morphological alterations. Membrane pore-size parameters calculated from the dextran clearances indicate that HDM leads to a detect in glomerular size-selectivity. The facts that maximal albuminuria tended to precede maximal excretion of IgG and that increases in albumin excretion were proportionately greater than those of dextran or IgG suggest that HDM also leads to a time-dependent defect in glomerular charge-selectivity.
