In 20 male and 20 female adult subjects, the volume of saliva in the mouth before (VMAX) and after (RESID) swallowing was determined. RESID could be computed by measuring the potassium and chloride concentrations in unstimulated saliva and in the expectorate after a five-second rinse with 5 ml of water immediately following a swallow. The mean value of RESID after a normal swallow was significantly higher in males (0.87 ml) than in females (0.66 ml). After a forced swallow, RESID was only slightly but significantly reduced, being 0.82 ml and 0.60 ml in males and females, respectively. The volume of saliva normally swallowed was calculated from the unstimulated salivary flow rate and the normal swallowing frequency. The mean value of VMAX (RESID plus volume normally swallowed) in males was 1.19 ml, which was slightly but not significantly higher than that in females (0.96 ml). When water was infused into the mouth at increasing flow rates, there was an increase in VMAX and in both the volume of fluid swallowed and the swallowing frequency.
在20名成年男性和20名成年女性受试者中，测定了吞咽前（VMAX）和吞咽后（RESID）口腔内唾液的体积。RESID可通过测量吞咽后立即用5毫升水冲洗5秒钟后未刺激唾液和咳出物中的钾和氯浓度来计算。正常吞咽后，男性RESID的平均值（0.87毫升）显著高于女性（0.66毫升）。强制吞咽后，RESID仅略有但显著降低，男性和女性分别为0.82毫升和0.60毫升。正常吞咽的唾液体积由未刺激唾液流速和正常吞咽频率计算得出。男性VMAX（RESID加上正常吞咽体积）的平均值为1.19毫升，略高于女性（0.96毫升），但差异不显著。当以递增流速向口腔内注入水时，VMAX、吞咽的液体体积和吞咽频率均增加。
