Background: Women having regular ovarian cycle often experience premenstrual syndrome which may be associated with alterations of autonomic nerve function due to fluctuation of ovarian hormones during different phases of ovarian cycle. Objective: To observe the parasympathetic nerve function status and their relationships with ovarian hormones during different phases of ovarian cycle in healthy young women. Methods: This cross sectional study was carried out in the department of Physiology at BSMMU, Dhaka in 2007 on 30 eumenorrhogic healthy females aged 20 to 30 years. Serum estrogen and progesterone were measured by MEIA method and parasympathetic nerve functions were assessed by valsalva, deep breathing test and orthostatic test during follicular and luteal phases of ovarian cycle. Data were analyzed by paired student 't' test, and Pearson's Correlation coefficient test where applicable. Results: Mean resting HR,SBP,DBP and all measures of parasympathetic nerve function were similar in all phases of ovarian cycle. With serum estrogen level, deep breathing showed significant (p<0.05) positive correlation in follicular and luteal phase and valsalva showed significant positive correlation during luteal phase. Conclusion: The results this study suggest that estrogen has got positive influence on parasympathetic nerve function which support cardioprotective role of estrogen in premenopausal females.

Background: Alteration of sympathetic nerve activity during different phases of menstrual cycle in healthy young women, has been found related with phasic fluctuation of ovarian hormones. Objective: To observe relation of sympathetic nerve function status with estrogen and progesterone during follicular and luteal phases of menstrual cycle in healthy young women. Methods: This cross sectional study was carried out in the Department of physiology of BSMMU, Dhaka from 1 st January to 31 st December 2007. Thirty apparently healthy unmarried women with age 20 to 30 years were selected. Sympathetic nerve function was evaluated by 2 reflex tests, orthostatic test and sustained handgrip, during the three phases of menstrual cycle. Serum estrogen and progesterone were measured during follicular and luteal phases. Data were analyzed by One way ANOVA, an unpaired t test and Pearson's correlation coefficient where applicable. Results: There were no significant significant differences among sympathetic nerve function parameters during three phases of menstrual cycle. Serum estrogen and progesterone showed non significant (p>0.05) relationship with sympathetic nerve function parameters. Conclusion: From this study it may be concluded that sympathetic nerve activity remains unaltered despite fluctuation of ovarian hormones in different phases of menstrual cycle in healthy young women.

“…Indeed, some recent studies have reported benefits of administering CPAP to females with PET [35,36]. In theory, the rise in carbon dioxide tension that would occur during inspiratory flow limitation could lead to sympatho-excitation and marked hypertension due to progesterone-mediated upregulation of catecholamine receptors [37].…”

Pre-eclamptic toxaemia (PET) may be associated with both endothelial dysfunction (ED) and sleep-disordered breathing (SDB). It was hypothesised that females with PET would demonstrate both SDB and ED, and that a correlation between these two would suggest a potential causative association.A total of 17 females with PET and 25 matched females with uncomplicated pregnancy were studied. They underwent a nocturnal ambulatory sleep study (using Watch_PAT100) and noninvasive evaluation of endothelial function utilising the reactive hyperaemia test (using Endo_PAT 2000). A higher ratio of post-to pre-occlusion pulse-wave amplitude (endothelial function index (EFI)) indicated better endothelial function.Females with PET had a significantly higher respiratory disturbance index (RDI) and lower EFI than controls (18.4¡8.4 versus 8.3¡1.3?h -1 , and 1.5¡0.1 versus 1.8¡0.1, respectively). Blood pressure significantly correlated with RDI and with EFI. EFI tended to correlate with RDI.In conclusion, these results suggest that both sleep-disordered breathing and endothelial dysfunction are more likely to occur in females with pre-eclamptic toxaemia than in females with uncomplicated pregnancies. The current authors speculate that respiratory disturbances contribute to the functional abnormality of the blood vessels seen in females with pre-eclamptic toxaemia, although causality cannot be determined based on this study.
