    Abstract:
    We have evaluated the effects of indomethacin (I) and of a rich in linoleic acid phosphatidylcholine (E) on the renal function during in bolo infusion of lysine-8-vasopressin (LVP). 5 normal subjects have been studied in the absence of treatment (TA) and after treatment with I, E, E+I respectively. Two clearance (cl.) periods have been performed in the following time intervals: 0-30 min and 30-60 min after in bolo LVP (1.5 m-U.kg-1) infusion. Have been measured: the urinary flow rate, V, the endogenous creatinine cl., Cc, the osmotic clearances, Cosm, CH2O, the sodium and potassium cl., CNa, CK, the urinary prostaglandins (PG) of E series excretion (UPGV) by RIA method and the mean of arterial pressure (PA). 1) In TA condition LVP decreases V, Cosm, Cc, CH2O, CNa, CK and slightly increases the urinary osmolarity; these effects regress during the interval 30-60 min. 2) In I condition LVP produces a significant increment of PA and prolonged and intensified decrement of Cc, CH2O, V; in this condition the increase of urinary osmolarity is greater than in TA condition. 3) The E-treatment alone does not affect the LVP-induced renal effects; however the enhancement of these effects produced by I is attenuated in the presence of E though UPGV does not differ in I and E+I.
