Abstract
To study the pathogenesis of parathyroid-hormone-induced renal insufficiency and the influence of the new calcium channel antagonist Gö 6070 (Gödecke AG, Berlin, FRG) rats were assigned to three groups (n = 8 each): (1) control, (2) PTH, (3) PTH plus Gö 6070. PTH (30 micrograms/24 h, a nonhypercalcemic dose) was administered i.p. and Gö 6070 (1 mg/kg/24 h) p.o. for 6 days. PTH did not change plasma or urinary calcium and did not induce nephrocalcinosis. The glomerular filtration rate (GFR), however, was decreased (4.9 vs. 10.3 ml/min/kg). Concomitant administration of Gö 6070 attenuated the PTH-induced fall in GFR (6.2 ml/min/kg).
