不同比例石膏知母配伍对Ca^(2+)浓度关系

Effects of Gypsum Fibrosum and Rhizoma Anemarrhenae in Different Proportional Compatibities on Concentration of Ca^(2+)

目的探讨不同比例的石膏与知母配伍与Ca2+浓度的关系。方法EDTA滴定法测定Ca2+浓度。结果石膏与知母配伍能显著增加Ca2+的浓度,但它不与石膏剂量成正比。结论临床使用石膏与知母药对,不宜盲目加大石膏剂量。

Objective To explore the relation between Gypsum Fibrosum and Rhizoma Anemarrhenae in different proportional compatibities and concentration of Ca^2＋. Methods Concentration of Ca^2＋ was determined by EDTA titration method. Results Content of calcium ion can be remarkably increased through the compatibity of Gypsum Fibrosum and Rhizoma Anemarrhenae, but it is not directly proportional to the dosage of Gypsum Fibrosum. Conclusion It is not suitable that adding the dosage of Gypsum Fibrosum blindly in clinical usage.
