Salivary sodium and potassium concentrations and ratios in a woman who experienced premenstrual tension. Figs. 4-6 relate to women who experienced definite pre- menstrual tension. In Fig. 4 the salivary and urinary Na/K ratios are compared. The latter (note that its scale is ten times that of the salivary Na/K ratio) is much more variable than the former, and neither shows any definite pattern. Certainly there is no evidence of sodium retention premen- strually. Fig. 5 shows the salivary Na/K ratios in another.
