摘　　要：对小鼠生后发育的不同时期腮腺分泌蛋白(PSP)表达的研究发现,在各发育期中,小鼠PSPmRNA的拷贝数是4.79E+06～1.32E+08,比三磷酸甘油醛(GAPDH,拷贝数是1.32E+04)高出102倍以上;并随腮腺发育期的不同呈动态变化:PSP表达量从初生到3周龄一直处于上升状态,到3周龄达到最高峰,3周龄以后开始下降;12周龄以后基本达到平稳状态。Expression features of mouse parotid secretory protein （PSP） in postnatal development of parotid glands have been re- searched in mRNA level. The copies of PSP mRNA were 4.79E±06 - 1.32E±08, which were 102 times higher than that of glyceraldehyde 3-phosphate dehydrogenase （GAPDH, 1.32E±04 copies） in different developmental stages. Messager RNA levels of PSP shifted with developmental stages： increased from birth to 3 weeks of postnatal, reached its peak at 3 weeks, then decreased; at last it kept at a even level at 12 weeks
