Rowland, Neil E., and Kenneth R. Morian. Roles of aldosterone and angiotensin in maturation of sodium appetite in furosemide-treated rats. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1453–R1460, 1999.— When rats are treated with furosemide, there is a rapid natriuresis. However, increased sodium appetite does not occur until some time later. One hypothesis to explain this d...

Brännström, Kristina, and William J. Arendshorst. Thromboxane A2 contributes to the enhanced tubuloglomerular feedback activity in young SHR. Am. J. Physiol. 276 (Renal Physiol. 45): F758–F766, 1999.—We performed micropuncture studies to determine the role of thromboxane A2 in the exaggerated tubuloglomerular feedback (TGF) activity in young spontaneously hypertensive rats (SHR). Glomerular fun...

Kirouac, Gilbert J., and Quentin J. Pittman. Identification of barosensitive neurons in the mediobasal forebrain using juxtacellular labeling. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1766–R1771, 1999.— Previous investigations suggest a possible role in cardiovascular regulation for neurons of the mediobasal forebrain. The present study was designed to determine the loca...

Liu, Gele, Leonard Kleine, Rania Nasrallah, and Richard L. Hébert. Bradykinin inhibits ceramide production and activates phospholipase D in rabbit cortical collecting duct cells. Am. J. Physiol. 276 (Renal Physiol. 45): F589–F598, 1999.—Recent reports suggest that inflammatory cytokines, growth factors, and vasoconstrictor peptides induce sphingomyelinase (SMase) activity. This results in the h...
