Imaging in rheumatoid arthritis using liposomes labelled with technetium.

Abstract

fracton are compatible with so alled vasomotor nephropathy as the cause of renal failure.2 Perhaps the differnces in renal haemodynamic properties between P blockers and the a and P blocker labetalol lead more readily to acute renal failure after an overdose of labetalol. Hypoteion leading to acute oliguric renal failure is accompanied by intense pregknoerular vasoconstriction, which makes filtration highly dependent on an adequately maintained postglomerular resistance.2 In thaWpeutic doses labetalol leads to a fall in renal vascular resistance; ,this is in contrast with most i blockers, which cause an increase.34 A fall in postglomerular resistance induced by labetalol, perhaps enhanced by the renal vasodilating effects ofdopamine in the dose used in our patient, may have been responsible for the failure of filtration.5
