Abstract

Background: Magnetized water has made many improvements in industry, agriculture and medicine. However its utilization in medicine still remains controversial.
Objective:  In this study we aimed to investigate the effects of magnetized water on height of epithelial cells in pre-implantation stage endometrium and fallopian tube and number of corpus lutea in female mice.
Materials and Methods:  Eighty female NRMI mice were recruited to this experimental study and randomly divided into two groups: the control group which drank normal water and the experimental (case) group which drank magnetized water for 2 weeks. Super-ovulation was induced in these mice and then they were mated with male mice as well. Samples of ovary, uterus and fallopian tube were obtained at the pre-implantation stage. Then, after preparation, the number of corpus lutea in each ovary was counted and the height of fallopian and endometrial epithelial cells was measured by light microscopy.
Results:  Data analysis showed a significant increase in the mean number of corpus lutea and the height of epithelial cells in fallopian tube comparing the case with the control group (p=0.01, p=0.002 respectively) whereas uterus epithelial cells of the case group showed insignificant increase in height, in compare with the control group (p=0.052).
Conclusion:  Our results suggest that magnetized water intake increases the number of corpus lutea and the height of fallopian tube epithelial cells. Further research is needed to determine whether this will increase in the success rate of fertility.

Abstract

Background: The Wingless-type (Wnt)/β-catenin signaling pathway controls cell homeostasis. Reproductive tissues are dynamic in response to steroidal hormone changes. Steroidal hormones are known to control the Wnt/β-catenin pathway, but their role in reproductive tissues remains unknown.
Objective: The present study aims to investigate the expression patterns of Wnt/β-catenin target genes in mouse reproductive tissues during the normal estrous cycle.
Materials and Methods: In this experimental study, 16 adult NMRI mice were grouped as proestrus, estrus, metestrus, and diestrus according to vaginal smear and histological evaluation of uterine and ovarian tissues. Uterine horns and ovarian tissues were collected. Reverse transcription quantitative polymerase chain reaction was performed to evaluate the expression of Wnt/β-catenin target genes (Myc2, Ppard, Id2, Birc5, and Ascl2) at different stages of the estrous cycle.
Results: The expression levels of Id2, Ascl2, and Pprd in uterine tissue were significantly higher at the proestrus phase than at the other stages. Meanwhile, Birc5 expression in uterine tissue was significantly higher at the metestrus stage than at the other stages. Furthermore, Myc2 expression was significantly higher at the diestrus stage than at the estrus and metestrus stages. In the ovarian tissue, the highest expression of Id2, Ascl2, and Birc5 was detected at the proestrus stage, whereas the highest expression of Myc2 and Ppard was observed at the estrus stage.
Conclusion: This study showed that Wnt/β-catenin target genes profiles are different among estrous cycle. It seems that different hormonal profiles during estrous cycles play a key role in the expression pattern of Wnt/β-catenin target genes in ovarian and uterine tissue.

Abstract

Background: Levels of estradiol decreases as women arrive the menopausal transition and enter to a low, steady level during the early postmenopause. In addition, memory dysfunction are highly prevalent during this period.
Objective: Our study was designed to determine whether endogenous levels of estradiol are related to cognitive function in postmenopausal.
Materials and Methods: The cross-sectional study was conducted between November 2015 to February 2016 on 209 healthy postmenopausal women. The women filled out the Montreal Cognitive Assessment (MoCA) scale. Then, estradiol level was tested for association with cognitive function adjusted for factors supposed to confound this association.
Results: The prevalence of cognitive dysfunction; MoCA points ≤26 in our participants was 62.7%, and mean±SD of estradiol level was 14.92±10.24pg/ml in participants with cognitive dysfunction in comparison with 21.67±14.92pg/ml in those with normal cognitive function (p<0.001). There were significant association between MoCA points with estradiol level (p<0.001) and educational status (p<0.001).
Conclusion: Estradiol replacement therapy in postmenopausal women with low endogenous estradiol levels and decreased cognitive function might be necessary.
