(17) Both the occupational and in particular the therapeutic exposure to coal tar resulted in clear increases in urinary levels of PAH metabolites as compared to unexposed subjects.
(18) Simultaneous imposition of the pH gradient (outward OH- gradient) and inward Na+ gradient stimulated PAH uptake significantly over that with an Na+ gradient alone.
(19) Using PAH as a marker for the maximal extractable perfusion flow, 1-naphthol could be regarded as a high-extraction compound even at high perfusion flow rates.
(20) Experiments with basolateral membrane vesicles prepared from rat kidney cortex were performed to study the mechanism by which p-aminohippuric acid (PAH) is taken up across the contraluminal membrane and is concentrated in proximal tubule cells.

Definition:
(interj.) An exclamation expressing contempt or disgust; bah !
Example Sentences:
