Abstract
OBJECTIVE:To study the secretion of catecholamine primary cultures of chromaffin cells from rat adrenal medulla were used.METHOD:Catechoalmines(norepinephrine,epinephrine and dopamine) were measured by high-performance liquid chromatography-electrochemical detection technique.RESULTS:Catecholamine released by chromaffin cells with in 20min without slimalus was (73.29±15.32) ng/106cells.When acetylcholine,nicotine or muscarine was added,the secretion of catecholamine was then increased.CONCLUSION:Using high-performance liquid chromatography-electrochemical detection technique,we can detect sensitively catecholamine released by cultured rat chromaffin cells.
