An increase in the blood hemoglobin concentration was found in four of five patients on chronic hemodialysis following subtotal parathyroidectomy performed for the treatment of incapacitating osteodystrophy. In a sixth hemodialyzed patient, there was a striking increase in the hemoglobin level following treatment with 1alpha-hydroxycholecalciferol with… (More)
The present study evaluated the effects and mechanisms of action of endothelin-1 (ET-1) on medullary and cortical blood flow (MBF and CBF, respectively). CBF and MBF were measured simultaneously by laser-Doppler flowmetry in anesthetized male Wistar rats. Bolus injection of ET-1 (1.0 nmol/kg iv) produced a sustained decrease in CBF (delta = -30%) and a… (More)
Eleven of 45 (24%) LG had proven N. This is approximately twenty times the incidence of N in the general population. The present study was undertaken to determine the factors that contribute to this high incidence of N in LG.
