摘　　要：目的用唾液腺动态显像定量分析方法评价唾液腺的摄取与排泄功能。方法用２种唾液腺定量分析软件，对３０例正常人和２０例干燥综合征患者的唾液腺功能进行分析，计算唾液腺１５ｍｉｎ摄取率和３０ｍｉｎ排泄率。结果正常人腮腺和颌下腺摄取率分别为（０２６±００９）％和（０１５±００８）％，而干燥综合征患者为（００７±００３）％和（００５±００４）％，两者比较差异有极显著意义，ｔ值分别为５３和４１，Ｐ均＜００１。不同定量方法评价唾液腺摄取功能的结果间呈显著正相关（ｒ＝０８５）。结论动态显像定量分析方法简单实用，能灵敏、可靠地评价唾液腺功能，有较重要的临床意义。Objective To evaluate the function of salivary gland by quantitative dynamic imaging Methods In thirty normals and twenty patients with Sjogren's syndrom (SS), absorption rate (15 min) and excretion rate (30 min) were calculated using two quantitative software Results Parotid and submandibular absorption rates in normal subjects were (026009)% and (015008)%, respectively; those of SS patients were (007003)% and (005004)%, t =53 and 41, both were P <001 There were markedly relativity between the two groups ( r =085) Conclusions Quantitative methods of analyzing salivary function is simple, sensitive, practical reliable for evaluating salivary function and also has important clinical significance
