Role of dopamine in the modulation of adrenal gland responses in the osmotically stressed pigeons, Columba livia.

چکیده
Salt loading on pigeons (C. livia) had stimulatory effects on brain amines (dopamine and 5-hydroxytryptamine), corticosterone, norepinephrine and epinephrine contents of adrenal gland. Conjoint administration of dopamine with hypertonic saline restored the brain amines and corticosterone of adrenal gland, but had no effect on catecholamine (CAM) contents of adrenal medulla. The excessive release of CAM in the plasma indicates sympathetic stimulation after both the treatments.
