...Michael J. Meldrum; Pat Glenton The potassium-induced release of 3 H-norepinephrine ( 3 H-NE) was examined in the rat caudal artery. A simple and reliable method was developed to examine stimulated neurotransmitter release from this highly innervated resistance vessel. The potassium-induced release...

...Michael J. Meldrum Potassium supplementation has been shown to decrease blood pressure in human and animal models of hypertension. The purpose of this study was to determine if potassium supplementation altered sympathetic nerve activity by altering 3 H-norepinephrine release in caudal artery...

...Guglielmina Froldi; Monica Montopoli; Miriam Zanetti; Paola Dorigo; Laura Caparrotta The effects of 5-hydroxytryptamine (5-HT), 5-carboxamidotryptamine, and sumatriptan on rat caudal arteries were examined, with the goal of finding experimental conditions useful in enhancing the ‘silent’ 5-HT 1B...
