    Abstract
    Pea protein hydrolysate (PPH) has antihypertensive effects and prostanoids have been implicated in renal diseases. To investigate the role of PPH and prostanoids on renal and cardiovascular effects in cardio-renal disease, normal and diseased Han:SPRD-cy rats were given diets containing either 0, 0.5% or 1% PPH for 8 weeks. At termination, diseased rat kidneys displayed increased renal cyst growth, fibrosis, plasma creatinine and lower monocyte chemoattractant protein-1. Diseased rats also exhibited left ventricular (LV) hypertrophy, elevated systolic and diastolic blood pressures and LV end diastolic and systolic pressures. Four of five prostanoids were elevated in diseased rat kidneys. PPH attenuated systolic blood pressure, but not other components of the cardio-renal syndrome. PPH also increased select prostanoids in normal and diseased rats. Thus, dietary PPH attenuates hypertension in the Han:SPRD-cy rat, but does not ameliorate other components of disease, possibly due to increased prostanoid effects or an insufficient treatment length.
