Abstract [en]

Hysterometry, a method for the quantitative evaluation of drug effect on the myometrium, has now been applied in a study of the changes in uterine tonicity during the menstrual cycle. Six nulli-gravidae women with regular menstrual periods and normal gynecological examination findings, were studied. Hysterometry was performed in the midproliferative, ovulatory, and midsecretory periods of the cycle and on the first day of menstruation. Uterine tonicity was found to be higher during the proliferative compared with the secretory phase. The change in uterine tonicity was correlated with a change in the quotient of concentration of estradiol and progesterone in serum (E2/P).

Abstract [en]

The ability of the uterus to contract in response to mechanical distension has been utilized in the development of a method, hysterometry, for the quantification of hormonal and pharmacological effects on the human myometrium in vivo. The method has been built up with due consideration for laws from mechanics of materials and hydrodynamics. By applying mathematical theorems and accepting certain approximations, the basic results of recordings of intrauterine pressure are transformed inte wall tension, allowing for the size of the uterus. The equivalent of an elasticity modulus in the myometrium has been used as a synthetic discriminator (without any real physiologic correlation) for the evaluation of hormonal and pharmacological effects.

Hysterometry har been used for the evaluation of uterine tonicity during the menstrual cycle. It was demonstrated that uterine tonicity is higher in the proliferative than in the secretory phase. The uterine tonicity correlated well with the concentrations in serum of estradiol and progesterone at the time of the examination.

Hysterometry has also been used for the evaluation of effects of inhibitors of prostaglandin synthesis (Naproxen Sodium and Naproxen acid) and of a selective beta-2-receptor stimulator (Salbutamol) upon the uterus in women with primary dysmenorrhea. It was shown that uterine tonicity was high on the first day of menstruation in untreated or placebo-treated dysmenorrheic women. Administration of inhibitors of prostaglandin synthesis or beta-2-receptor stimulating agents markedly decreased the uterine tonicity and relieved the menstrual pain.
