柠檬喷雾剂与乌梅喷雾剂促进唾液分泌的效果对比

Comparison of Effect Between Lemon Spray and Wumei Spray on Stimulation of Salivary Secretion

目的:应用自制柠檬喷雾剂和乌梅喷雾剂分别对健康人的唾液腺分泌进行干预,观察2种喷雾剂对唾液腺生理功能及生化指标的影响。方法:收集某大学42名志愿者的唾液,采用自身前后对照,分为基础唾液组、柠檬喷雾组和乌梅喷雾组,对3组的唾液流率指数与p H、唾液淀粉酶、Na+、K+、Na+/K+等结果进行比较。结果:乌梅喷雾组唾液流率指数高于基础唾液组(P<0.05),柠檬喷雾组p H值高于基础唾液组和乌梅喷雾组(P<0.01),柠檬喷雾组与乌梅喷雾组的淀粉酶、Na+、K+浓度均低于基础唾液组(P<0.01);柠檬喷雾组K+浓度低于乌梅喷雾组(P<0.01),Na+/K+比值低于基础唾液组(P<0.01)。结论:乌梅喷雾剂促进唾液分泌的效果比柠檬喷雾剂更为显著,而柠檬喷雾剂在调节口腔酸碱度方面具有保护口腔的作用。

Objective： To intervene the salivary secretion of healthy people with self-made lemon spray and Wumei spray, and to observe the effect of the two sprays on the physiological function and biochemical indexes of salivary gland. Methods： Collected saliva from 42 college volunteers, adopted self-control study method to divide them into basal saliva group, lemon spray group and Wumei spray group. Compared the exponential function of saliva flow rate, pH, salivary amylase, Na＋, K＋, and Na＋/K＋ ratio among the three groups. Results： The exponential function of saliva flow rate of Wumei spray group was higher than that of basal saliva group（P〈 0.05）. The pH value of lemon spray group was higher than that of both Wumei spray group and basal saliva group（P〈 0.01）. Concentrations of amylase, Na＋ and K＋ of both lemon spray group and Wumei spray group were all lower than those of basal saliva group（P〈 0.01）. The concentrations of K＋ of lemon spray group were lower than those of Wumei spray group（P〈 0.01）, and Na＋/K＋ ratio of lemon spray group was lower than that of basal saliva group（P〈 0.01）. Conclusion： The effect of stimulating salivary secretion of the Wumei spray is more significant than that of lemon spray, while lemon spray plays a protective role in adjusting the pH value of oral cavity.
