Intracarotid infusions of noradrenaline (0.15 nmol · kg−1 · min−1) either alone or accompanied by phentolamine (1.5 nmol · kg−1 · min−1) caused similar-sized increases in salivary protein, magnesium and bicarbonate, and decreases in osmolality, sodium, potassium and chloride whereas intravenous noradrenaline stimulated much smaller responses. Concurrent infusions of the β1-antagonist, CGP20712A, blocked these noradrenaline-induced changes in salivary composition more effectively than equimolar… CONTINUE READING
