摘　　要：目的　研究大鼠颌下腺 Gn RH受体基因的存在及其基因序列。　方法　从 SD大鼠颌下腺提取总RNA,用 RT- PCR法扩增 Gn RH受体基因 ,利用双脱氧链终止法对扩增产物进行序列测定。　结果　从 SD大鼠颌下腺扩增出 Gn RH受体基因的特异性条带 ,经序列分析 ,扩增产物的基因序列与文献报道大鼠脑垂体的完全一致。结论　大鼠颌下腺有 Gn RH受体基因的表达 ,能合成 Gn RH受体 ,是 Gn RH的靶器官 ,颌下腺产生的 Gn RH可作用于颌下腺的靶细胞 ,参与颌下腺生理功能的调节。Objective\ To study whether gonadotropin releasing hormone receptor (GnRHR)mRNA exist in rat submaxillary gland and it's gene sequence. Methods\ The total RNA isolated from rat submaxillary gland was amplified by RT\|PCR, the PCR products were identified by sequencing with Sanger's method. Results\ The specific amplified band of GnRHR mRNA was detected through agarose gel electrophoresis and gene sequence is identical to the sequence of GnRHR which has been reported in rat pituitary. Conclusion\ GnRHR can be produced by submaxillary and response for modulating biological function of submaxillary.\;
