• Resumen

  • The effect of intrarenal infusion of PAF-acether was studied in dogs. PAF-acether infusions caused a dose-dependent decrease in glomerular filtration rate, renal blood flow and urinary flow and electrolyte excretion, without significant changes in mean arterial pressures. In addition, the higher doses used caused also increases in packed cell volume, and decreases in plasma proteins and leukocyte and platelet count, whereas the lower doses did not elicit those changes. These data suggest that PAF-acether causes an impairment in renal function which is in part mediated by vasoactive substances released from platelets and leukocytes.
