目的：无刺激全唾液流率（UWSFR）的性别差异可能是由于唾液腺大小的差异。在这项研究中，我们探讨了UWSFR之间的关系，腺体的大小和身体大小的健康年轻的成年mates和femines.Design：50名健康年轻的成年人的无刺激的全唾液的吐痰法收集5分钟，并测量唾液的流速。测量身高和体重，并计算体重指数（BMI）。唾液腺的大小进行了测量，通过使用的磁共振成像techniques.Results：腮腺和颌下腺的大小和流量在女性显着小于那些在交配，也是体重，身高和BMI。在雄性和雌性中，腺体大小与流量、体重和BMI呈显著正相关。通过将它们与腺体大小、重量和BMI.Conclusions标准化，减少了流速的变化：这些结果表明，与配偶相比，女性的UWSFR较低是由于较小的腺体大小，由于较小的身体尺寸。(c)2006爱思唯尔有限公司版权所有。
Objective: A gender difference in the unstimulated whole saliva flow rate (UWSFR) may be due to a difference in the sizes of the salivary glands. In this study, we investigated the relationships among the UWSFR, gland sizes and body sizes of healthy young adult mates and females.Design: Unstimulated whole saliva was collected for 5 min by the spitting method in 50 healthy young adults, and the flow rate of the saliva was measured. Heights and weights were measured, and body mass indices (BMI) were calculated. The sizes of the salivary glands were measured by use of a magnetic resonance imaging technique.Results: Parotid and submandibular gland sizes and flow rates in females were significantly smaller than those in mates, as were also the weights, heights and BMI. In both mates and females, there were significant positive correlations between gland sizes and the flow rates, weights and BMI. The variations of the flow rates were reduced by standardizing them with gland sizes, weights and BMI.Conclusions: These results suggest that the lower UWSFR in females as compared with mates is due to the smaller gland sizes due to the smaller body sizes.
