The activities of uteroferrin, measured as acid phosphatase (AP), and an aminoacylpeptidase (AA) were measured in uterine flushings collected from gilts on Days 6, 8, 10, 12, 14, 15, 16 and 18 of the oestrous cycle and pregnancy (N = 37). Changes in AP (P less than 0.05) were associated with day for both specific and total AP in non-pregnant and pregnant gilts. For pregnant and non-pregnant gil...

UNLABELLED Under progesterone (P) dominance, fluid loss assists uterine closure which is associated with pH reduction. We hypothesize that P inhibits uterine fluid secretion and HCO3⁻ transport. AIM To investigate the expression of Cystic Fibrosis Transmembrane Regulator (CFTR) and Cl⁻/HCO3⁻ exchanger (SLC26A6) under P effect. METHOD Uteri from ovariectomized steroid replaced and intact rat...

Isolated uterine vascular beds from virgin and pregnant rats were used to assess vascular reactivity and the ability of nitric oxide (NO), prostanoids and endothelium-derived hyperpolarizing factor (EDHF) to modulate these responses. One uterine horn from female rats in each oestrous cycle day and gestation day 17 was removed and perfused with physiological saline solution. Tone was induced wit...

Abstract In cows embryo transfer occurs on the 7 th day of oestrous cycle. Embryo survival and successful pregnancy depend many factors, including early interaction between endometrium. Therefore, aim our research was to describe histo-morphological characteristics endometrium in donor recipient obtaining day, respectively (7 oestrus cycle). addition, progesterone oestradiol levels, ipsilateral...

Hedberg Alm, Y. 2006. Oestrus in the mare with emphasis on deviant behaviour and adrenal gland function. Some owners appear to experience problems with their mares due to excessive oestrous signs and/or changes in their mare's behavioural characteristics across the oestrous cycle. Few such mares are examined at equine clinics and, thus, the cause of such behaviour is often unknown. Adrenal sex ...
