[The analysis of sodium, potassium and calcium concentration in myomas, myometrium and peripheral blood].

We have examined the concentration of sodium and potassium in myomas, myometrium and peripheral blood of 55 women and in 69 women calcium was examined. The levels of these elements were correlated to the phase of the menstrual cycle. The sodium concentration is similar in the examined tissues in both phases. The potassium concentration is significantly higher in myomas and myometrium in comparison with the peripheral blood in both phases of the menstrual cycle. The calcium concentration is significantly lower in myomas and myometrium during the proliferation and significantly lower in the myomas comparing to the myometrium and peripheral blood in the secretion. Concerning the differences between two phases of the cycle we observed that the level of the potassium is significantly lower in the myomas in the proliferative phase but the the level of the sodium is higher in the secretory phase.
