This study investigated an influence of oestradiol and progesterone on expression of LH/hCG receptors in the porcine uterine broad ligament. The tissues were obtained from nineteen ovariectomized crossbred gilts. The animals received i.m. injections of 2 ml of corn oil (control; n=4), 25 μg kg-1 of oestradiol benzoate (n=5), 500 μg kg-1 of progesterone (n=5) or 25 μg kg-1 of oestradiol benzoate with 500 μg kg-1 of progesterone (n=5) daily for 5 consecutive days before slaughter. It was found that oestradiol increased the number of receptors in arteries of all areas in the uterine broad ligament, in veins located near the uterine horn and in the ovarian vein as well as in the ligament musculature in the area of vessels located near uterine horn. Progesterone decreased the expression of receptors in all tissues from the area of vessels located about 4 cm below the uterine horn, but augmented their expression in the ovarian vein and in muscular layers of the broad ligament in the area of the uterine vessels trunk. Oestradiol with progesterone increased amount of receptors in arteries from the area of uterine vessels branches, in ovarian vessels^ in veins from areas of branches and trunk of uterine vessels as well as in muscular layers of the broad ligament collected from areas of uterine vessels trunk and paraovarian plexus. These results indicate that oestradiol and progesterone are responsible for changes in expression and distribution of LH/hCG receptors in the broad ligament of the porcine uterus.

The overall objective of this study was to examine the effect of vaginal administration of prostaglandin E₂ (PGE₂) and/or17β-estradiol (E₂) on luteal function maintenance and histological properties of the porcine cervix. For this purpose, crossbred gilts were divided into three groups (n=5 per group) supplied on days 11-16 of the estrous cycle with suppositories containing: (1) placebo (Group I, Control); (2) 0.4 mg of E₂ (Group II); (3) 0.4 mg of E₂ and 2 mg of PGE₂ (Group III). Blood samples were collected on days 11-19 of the estrous cycle to determine the concentration of progesterone (P₄). Additionally, to examine local effects of the hormones applied, segments from the uterine and vaginal parts of the cervix and from the ovaries were collected post-mortem. Prolonged luteal function and extended synthesis of P₄ were observed in 2 of 5 gilts receiving PGE₂ and E₂ simultaneously (Group III). Then, these gilts were subdivided into Group IIIA (n=2; presence of corpora lutea on the ovaries) and Group IIIB (n=3; lack of corpora lutea). Increased levels of plasma P₄ were observed in Group IIIA on days 15-19 compared to Group IIIB and on days 16-19 compared to Group I and Group II (P<0.05; P<0.01; P<0.001, respectively). In the cervix of gilts in Groups II and III, enlarged blood vessels in the lamina propria of both parts of the cervix were observed. Furthermore, in Group II the epithelium of the uterine part of the cervix was thicker (P<0.001). Our study confirmed the proposed luteotrophic/antiluteolytic actions of E₂ and PGE₂ applied intravaginally. These results are significant considering that very low doses of E₂ were used when compared to previous attempts. Despite the inadequate response to treatments in some of the gilts, the local effects of these hormones on the histological properties of the porcine cervix suggest that further improvements in the vaginal administration route might help to elaborate new methods for enhancing the luteal function in the pig.
