在20名男性和20名女性成年受试者中，测定了吞咽前（VMAX）和吞咽后（RESID）口腔中的唾液体积。RESID可通过测量未刺激唾液和吞咽后立即用5 ml水冲洗5 s后的痰液中的K和Cl浓度来计算。男性正常吞咽后的RESID平均值（0.87 ml）明显高于女性（0.66 ml）。强制吞咽后，RESID仅轻微但显著降低，雄性和雌性动物分别为0.82 ml和0.60 ml。正常吞咽的唾液体积由未刺激的唾液流速和正常吞咽频率计算。男性的VMAX（RESID加正常吞咽量）平均值为1.19 ml，略高于女性（0.96 ml），但不显著。当水以增加的流速注入口中时，VMAX增加，吞咽的液体体积和吞咽频率也增加。
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 K and Cl concentrations in unstimulated saliva and in the expectorate after a 5 s 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.
