Abstract
Dopamine and norepinephrine concentrations in the stomach, duodenum, and brain were measured after subcutaneous injection of tyrosine methyl ester in the rat. Tyrosine significantly increased dopamine concentrations in each tissue without altering norepinephrine levels. The increase in dopamine concentration in the stomach or duodenum was observed 1 h after tyrosine methyl ester injection, but it returned to normal 4 h after the administration of the chemical.
摘要
给大鼠皮下注射酪氨酸甲酯后，测量了其胃、十二指肠和大脑中的多巴胺和去甲肾上腺素浓度。酪氨酸显著增加了每个组织中的多巴胺浓度，而不改变去甲肾上腺素水平。在注射酪氨酸甲酯1小时后，观察到胃或十二指肠中的多巴胺浓度增加，但在给予该化学物质4小时后又恢复正常。
