Abstract/OtherAbstract:
1. Change with time of the content and uptake of dopamine (DA) and noradrenaline (NA) in the renal, superior mesenteric and femoral arteries and abdominal aorta of rabbit after reserpine administration was examined. Endogenous DA and NA were measured by high performance liquid chromatography coupled with electrochemical detector. 2. A single dose of reserpine (3 mg/kg, i.p.) maximally depleted the endogenous DA and NA contents in the four blood vessels 24 h after the administration; the ratios of reductions were 70-90% and approximately 90% of the normal levels, respectively. The DA contents in all four vessels recovered to the normal level within 4 days after reserpine. However, NA content did not recover to the normal levels within 30 days after reserpine except in the mesenteric artery. 3. The activity of dopamine beta-hydroxylase (DBH) significantly increased in all four blood vessels 1 h after reserpine. Although the DBH activity returned to the normal level after 3 days in the mesenteric artery, it returned within 24 h in the other three vessels. 4. [3H]-Dopamine and [3H]-NA uptake were almost completely depressed 1 h after reserpine. The [3H]-NA uptake in four vessels recovered to the normal level 2-14 days after reserpine, and [3H]-DA uptake recovered after 30-45 days. Thus, the endogenous DA content in blood vessels was completely restored although DA uptake and NA content were still affected. 5. These results suggested that the recovery of stored DA after reserpine was faster than that of stored NA and the recovery of DA uptake after reserpine was slower than NA uptake.(ABSTRACT TRUNCATED AT 250 WORDS)
