Example Sentences:
(1) The syndrome of hyporeninemic hypoaldosteronism (SHH) is not infrequent in adults with chronic renal failure caused by chronic tubulointerstitial nephritis, but it has been reported rarely in children.
(2) The concentration and ratio of AI conversion into AII were significantly increased in LRS rats (P < 0.05), but decreased in HH and SHH rats (more markedly in HH rats).
(3) Fractional potassium excretion was curvilinearly related to glomerular filtration rate (GFR), but in all three patients with SHH it was lower than expected for the level of GFR present.
