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: It has been hypothesized that blastocyst integrin expression changes can affect the spontaneous miscarriage in polycystic ovarian syndromes (PCOS).
Objective: In this study, the profile of integrin genes and proteins was investigated on blastocyst of the PCOS experimental mouse model.
Materials and Methods: 30 NMRI female mice were equally divided into 3 groups: control, experimental [PCOS that was injected estradiol valerate (40 mg/kg)]. After 8 weeks, each group was hyper stimulated by PMSG and HCG. Vaginal plaque was checked, and mice were investigated 5 days after the test. Progesterone and estradiol levels were determined; α4, αv, β1 and β3 integrin genes and protein of blastocysts were examined by real time PCR method and immunohistochemistry, respectively.
Results: Estradiol level was significantly increased (p≤0.035) in PCOS group. Based on our finding, the ratio of geneschr('39') expressions αv, β3, β1 and α4 in PCOS to control group was 0.479±0.01, 0.5±0.001, 2.7±0.4 and 1.023±0.2 respectively. Genes expression showed a great difference (p≤0.001) between β3, β1 and αv in PCOS compared to other groups. αv and β3 integrin proteins expressed in all groups but intensity of these proteins in PCOS groups, was lower than other groups.
Conclusion: Pattern of αv and β3 integrins expression on the mouse blastocyst surface has an important effect during the implantation window. This pattern has changed in PCOS model and might have a great influence on implantation failure. Therefore, this experimental study suggests that a great attention to this problem may be essential in patients who are involved.

Abstract

Background: Endometrial integrin expression changes might be a reason for implantation failure in polycystic ovarian syndromes (PCOS).
Objective: Assessment of integrin genes and proteins expression upon endometrium in the PCOS experimental mouse model was the main goal of this study.
Materials and Methods: 30 NMRI female mice were equally divided into control, experimental (PCOS; received estradiol valerate (40 mg/kg)) and sham group (received; olive oil). After 8 weeks, each group was hyper stimulated by 7 IU PMSG and then, after 48hrs, 7 IU HCG was injected. Vaginal plaque was checked. After 5 days, Progesterone and estradiol levels and endometrial tissues were investigated to evaluate of α4, αv, β1 and β3 integrins gene and protein by qPCR method and immunohistochemistry, respectively.
Results: Tissue samples were assessed and showed that level of progesterone was significantly decreased in PCOS group. Results of molecular part in the amount of αv, β3, β1 and α4 gene expressions showed a great difference in β3 and αv genes expressions between experimental groups. αv, β3, α4 and β1 proteins in the endometrial stroma in the control group were expressed, but they were not detected in PCOS group.
Conclusion: According to the results, integrins had different expression patterns in different areas of the endometrium; such as epithelial and stromal. It seems that in PCOS, this pattern has changed and the results might have a great influence on implantation failure. Therefore, this study suggests that a great attention to this problem may be essential in patients who are involved.
