The aim of this study was to investigate the relation between ovarian blood flow, folliculogenesis and sex-steroid production during normal menstrual cycle and in women with ovarian failure. Ten healthy women and 40 patients with ovarian failure underwent hormonal assays (follicle-stimulating, luteinizing hormones, estradiol, progesterone, prolactine, testosterone) and ultrasound examination of the uterus and ovaries with color Doppler ultrasonography of the uterine and ovarian vessels on the 3 -5th, 11- 13th, 17- 19th and 21 -23rd days оf menstrual cycle. Intraovarian blood flow of the ovary carrying the predominant follicle in healthy women appeared more active than in conrdlateral ovary on the 3-5th days of the cycle. Inpatients with ovarian failure no difference was detected between the ovaries during the periods in question. Ovarian and uterine blood flow inpatients with the ovarian failure was less intensive comparingwith healthy women. Positive correlation between uterine blood flow and estradiol concentration in serum was revealed.

Fescue toxicity is a nutritional-related disease generated in a forage-based beef herd exposed to ergot alkaloids (i.e. ergovaline) present in endophyte-infected tall fescue that produces important economic losses. The combination of a genetic test for susceptibility to fescue toxicity and supplementation with rumen-protected niacin could potentially reduce the toxic effects of ergovaline on beef cow and heifers’ reproductive performance during mid-gestation by improving uterine blood flow. Our main objective was to use color Doppler ultrasonography to evaluate the occurrence of any alteration in uterine arterial blood flow in pregnant, genotyped beef cows and heifers exposed to endophyte-infected tall fescue seeds and supplemented with rumen-protected niacin. We hypothesize that genetically-tested susceptible control beef cows will have narrower uterine arteries and decrease blood flow as compared to tolerant cows that received rumen-protected niacin. Rumen-protected niacin was selected for this study due to its well-known effect as a vasodilator. Therefore, it might help cope with blood vessel constriction generated by ergovaline present in endophyte-infected tall fescue seeds. Results showed the negative effect of exposure to ergovaline in the uterine blood flow of pregnant beef cattle through an increase in the resistivity index. No Doppler parameters detected positive effects of genetic and nutritional treatments.

SummaryIncreased serum levels of endogenous as well as exogenous estrogen are regarded to be responsible for acquired activated protein C (APC) resistance. It was the objective of this study to evaluate whether the physiological increase in serum estradiol concentration during the normal menstrual cycle affects the individual’s sensitivity to APC. Seventy-two women with normal menstrual cycles were included in the study. Blood samples for analysis of estradiol (E2), progesterone (P4) and APC resistance were drawn at two time points of the menstrual cycle (day 3–5 and day 22–25). Two methods of measuring APC resistance were used: the activated partial thromboplastin time (aPTT)-based assay and the endogenous thrombin potential (ETP)-based APC resistance test. Independent of the method used, no changes in APC resistance were found, even though the E2 concentration increased significantly between the two menstrual phases. No correlations between E2 levels and APC resistance, P4 levels and APC resistance or changes in E2 concentrations and changes in APC resistance were detected. Ten women were carriers of the factor VLeiden mutation. Their baseline APC resistance was increased, but their response to elevated E2 during the menstrual cycle did not differ from that of non-carriers. In conclusion, our observations suggest that physiological differences in serum levels of estradiol and progesterone between the early follicular and the luteal phase in a normal menstrual cycle do not have any significant impact on the individual’s sensitivity to APC.
