    Streszczenie angielskie: Recent studies have suggested association between the elevated homocysteine levels and pregnancy complications. The aim of this study was to investigate the effects of homocysteine on spontaneious contractions of myometrium isolated from pregnant guinea pig. Full-thickness myometrial strips were obtained from late-pregnant guinea pigs following decapitation, and suspended in an organ bath which was filled with physiological saline solution (pH 7.4), maintained at 37řC and continuosly bubbled with 95 p.c. O2 and 5 p.c. CO2. After the observation of spontaneous contarctions under one gram of resting tension, homocysteine (0.2, 0.5 and 1 mM) was added to the organ bath and effects off this agent on frequency and amplitude of contractions were evaluated in 20 min periods. One-way analysis of variance was used for statistical analysis of the data. Homocysteine caused increase in both frequency and amplitude of spontaneous contractions in a dose-dependent manner. The results from this in vitro study indicate that cardiovasular risk factor homocysteine has contracting pharmcological effects on guinea pig myometrium.
