Abstract
Micropuncture studies were performed in Munich Wistar rats made diabetic with streptozotocin and in normal control rats. Diabetic rats received daily ultralente insulin to maintain moderate hyperglycemia (approximately 300 mg/dl). Group 1 diabetic rats studied after routine micropuncture preparation exhibited elevation of the single nephron glomerular filtration rate (SNGFR) due to increases in the glomerular transcapillary hydraulic pressure difference and glomerular plasma flow rate. In group 2 diabetic rats infusion of insulin to achieve acute blood glucose control normalized the glomerular transcapillary pressure gradient while increasing the glomerular ultrafiltration coefficient, so that SNGFR remained elevated. Persistent elevation of SNGFR despite normalization of the transcapillary pressure gradient was also observed in group 3 diabetic rats infused with insulin plus sufficient dextrose to maintain hyperglycemia. These studies indicate that glomerular capillary hypertension in diabetes is an acutely reversible consequence of insulin deficiency and not the result of renal hypertrophy.
