The purpose of this study was to determine the nature of the permissive effect of atrial stretch on atrial natriuretic peptide (ANP) secretion and the mechanism for the rapid termination of endothelin (ET) signaling following the removal of ET-dependent stimuli. Basal ANP release was not affected by either an elevation or inhibition of nitric oxide (NO) activity, but stretch-stimulated ANP release was significantly reduced from 144 +/- 20% to -3 +/- 7% of the baseline by increased NO activity. Furthermore, while the response to ET alone at low pressure was 37 +/- 13% of the baseline ANP secretion rate (P > 0.05), this response increased to 137 +/- 27% (P < 0.05) when NO activity was blocked, a response equal to the control high-pressure response (144 +/- 20%). Thus the reduction in NO activity is a permissive effect of stretch, and NO can rapidly terminate an ET-stimulated ANP response. Therefore, stretch-induced ANP secretion is regulated by a reciprocal interaction between locally produced ET, which appears to increase, and NO, which appears to decrease.

Abstract. Nitrous acid (HONO) has been quantitatively measured in-situ by differential photolysis at 385 and 395 nm and subsequent detection as nitric oxide (NO) by the chemiluminescence reaction with ozone (O3). The technique has been evaluated by FT-IR to provide a direct HONO measurement in a simulation chamber, and compared side-by-side with a LOng Absorption Path Optical Photometer (LOPAP) in the field. The NO/O3 chemiluminescence technique is robust, well characterized and capable of sampling at low pressure whilst solid-state converter technology allows for unattended in-situ HONO measurements in combination with fast time resolution and response.
