摘　　要： 通过腹腔注射药物、尾静脉取血、放射免疫测定激素含量等方法研究L-多巴等几种药物对草鱼鱼种生长激素分泌的影响，发现腹腔注射L-多巴、阿朴吗啡可以显著提高草鱼鱼种血清生长激素水平，而腹腔注射多巴胺、去甲肾上腺素、肾上腺素和6-羟多巴则可明显降低草鱼鱼种血清生长激素水平。说明儿茶酚胺类参与了草鱼鱼种生长激素的分泌调节，L-多巴或其代谢物是通过中枢神经系统促进草鱼鱼种生长激素分泌的，而多巴胺、去甲肾上腺素和肾上腺素则是在脑垂体水平上抑制草鱼鱼种生长激素的分泌。 I. P. injection of L-dopa and apomorphine could significantly increase serum GH concentration of grasscarp fingerlings. However, I. P. injection of dopamine, norepinephrine, epinephrine and 6-hydroxydopamine could decrease serum GH concentrations of grasscarp fingerlings. These results indicated that catecholaminergic drugs may be able to regulate the GH secretion of grasscarp fingerlings. It is suggested that L-dopa or its metabolites may stimulate GH secretion possibly by central nervous system in grasscarp fingerlings, but dopamine, norepinephrine and epinephrine may inhibit GH secertion possibly by influencing pituitary GH cells in grasscarp fingerllings.
