The aim of this study was to investigate whether apamin-sensitive K+ channels play a role in the NO induced relaxation of the human pregnant myometrium. Concentration-response curves for sodium nitroprusside (SNP) (10-9 – 10-4 M) were constructed in the absence and presence of 10-8 M apamin and 10-7 M charybdotoxin (CTX). Preincubation with apamin resulted in a significant attenuation of the relaxation caused by SNP, while pre-treatment with CTX insignificantly decreased the SNP induced relaxation. Our findings suggest that apamin-sensitive K+ channels exist in the human pregnant myometrium and play a role in modulation of the myometrium response to NO donors.

The aim of the present study was to determine 1) concentrations of NOx in the myometrium of pregnant gilts, and 2) the influence of estradiol-17ß (E2) and/or progesterone (P4) on NOx production by the porcine myometrium on days 5, 10, 15, 20, 25, 30, 35, 40 and 60 of pregnancy (n = 5 per day). Total NOx concentrations were determined using a microplate assay method based on the Griess reaction. During the first 60 days of gestation, a triphasic pattern in the concentration of NOx in the porcine myometrium was observed with a peak on days 10-15, 30 and 60 of gestation. We also demonstrated the stimulatory effect of E2 and/or P4 on in vitro NO production by the porcine myometrium. The stimulatory effect of steroid hormones on NOx release depended on the treatment dose of steroids and day of pregnancy. These data suggest that locally produced NO may inhibit spontaneous uterine contraction and therefore is involved in the maintenance of myometrial quiescence during pregnancy.

The aim of this study was to analyse the expression of gap junction proteins, connexins, in non-pregnant porcine myometrium. Uterine tissue was obtained immediately after slaughter of the animals and the examination of ovarian morphology. Tissues were collected from prepubertal and mature pigs at preovulatory and secretory phases of the oestrous cycle and frozen in liquid nitrogen. Cryosections were immunofluorescently labelled using antibodies against connexins 26, 32, 40 and 43. Among four connexins studied, only connexin 43 was detected in the myometrium of the immature and adult porcine uterus. Connexin 43 labelling appeared as bright fluorescent spots distributed along smooth muscle cell interfaces. The amount of labelling for Cx43 was much higher in the circular layer than in the longitudinal layer in all prepubertal and mature porcine myometria. These results support the concept that connexin 43 is the principal connexin expressed in the nonpregnant myometrium. Furthermore, it seems that muscle layer-specific distribution of connexin 43 gap junctions may contribute to diverse functions of circular and longitudinal smooth muscles in modulating uterine motility.

This study investigated whether activin A and an inhibin-a subunit fragment (INHα) could permeate in a periovarian vascular complex from ovarian effluent into the ovarian artery and be retrograde transferred into the ovary. Radiolabelled activin A (125I-activin A) and INHα (125I-INHα) were injected (2.7xl07 dpm) into follicles or corpora lutea (CL). It was demonstrated that 125I-activin A and 125I-INHa were released into the ovarian effluent and permeated into the arterial blood supplying the ovary in both phases of the cycle. The concentration of 125I-activin A in ovarian arterial blood was higher in the luteal phase (LP) than in the follicular phase (FP) (P<0.0001) in contrast to 125I-INHα which was higher in the FP (P<0.0001). The concentration of 125I-activin A in uterine tissues generally did not differ between the phases of the estrous cycle, but the concentration of 125I-INHα was higher (P<0.05) in the FP than in the LP. The concentration of 125I-activin A was higher in the LP in samples of endometrium and myometrium (P<0.05), as well as mesometrium (P<0.01), and higher in the FP in samples of mesometrium (P<0.05) close to the ovary than in the samples adjoining the uterine body. In the FP, the concentration of 125I-INHa was higher in endometrium and mesometrium close to the ovary than in samples adjoining the uterine body (P<0.05). In conclusion, the study demonstrated that it was possible for INHa and activin A to be retrograde transferred to the ovary. Thus this transfer could elevate their concentration in arterial blood supplied to the ovarian follicles or CL and may influence production of these peptides in the ovary, modulating ovarian function.
