Dihydropyridine Ca2+ channel blockers (CCBs) are widely accepted in the treatment of premature labour. Their mechanism of action in tocolysis involves the blockade of L-type Ca2+ channels, influenced by the Ca2+-activated K+ channels, beta-adrenergic receptors (β-ARs) and sexual hormones. In clinical practice, most experience has been gained with the use of(More)
AIM To study the effects of d- and l-limonene on pregnant rat myometrial contractility in vitro, and investigate how these effects are modified by other agents. D- and l-limonene (10(-13)-10(-8) M) caused myometrial contraction in a dose-dependent manner. METHODS Contractions of uterine rings from 22-day-pregnant rats were measured in an organ bath in the(More)
AIM To assess the effect of 17β-estradiol pretreatment on the function and expression of α2- adrenergic receptors (ARs) subtypes in late pregnancy in rats. METHODS Sprague-Dawley rats (n=37) were treated with 17β-estradiol for 4 days starting from the 18th day of pregnancy. The myometrial expression of the α2-AR subtypes was determined by real time(More)
BACKGROUND The adrenergic system and progesterone play major roles in the control of the uterine function. Our aims were to clarify the changes in function and expression of the α2-adrenergic receptor (AR) subtypes after progesterone pretreatment in late pregnancy. METHODS Sprague Dawley rats from pregnancy day 15 were treated with progesterone for 7(More)
