Introduction: In maternal and neonatal cases, preeclampsia is a multi-organ, heterogeneous pregnancy condition associated with significant morbidity and mortality. Since preeclampsia is a progressive disease, in some cases, delivery is necessary to stop the progression to the benefit of the mother and foetus. However, the need for early delivery has adverse effects on significant neonatal outcomes that are not limited to the most premature babies. The results include oxidative stress in the disease and invoke the biochemical basis for antioxidant clinical trials to prevent and treat hypertension caused by pregnancy. In the management of preeclampsia, supplementation of antioxidants along with polyunsaturated fatty acids, particularly omega-3 fatty acids, may be useful. This describes vitamin Ds potential role in the pathogenesis of preeclampsia. However, the role of vitamin D supplementation and dosing is controversial in preventing preeclampsia. Method: The study was carried out from March 2019 to April 2020 at Shalinitai Meghe Hospital and Research Centre using institutional-based cross-sectional study design among women whose age was greater than or equal to eighteen. Data were collected using a standardised and pretested questionnaire from 150 participants by face-to - face interview technique. Using Chemiluminiscent Immunoassay (CLIA), vitamin D estimation was performed. The behaviour of Glutathione Reductase was calculated according to the Goldberg et al 1983 procedure. To classify the factors associated with the development of preeclampsia, logistic regression analysis was used. Result: With a mean age of 30.28, a total of 150 participants were enrolled in the study. Evaluation of vitamin D and glutathione levels The prevalence of preeclampsia among current pregnant women attending ANC at Shalinitai Meghe Hospital was 16 with a 95 % CI. The current preeclampsia was significantly correlated with predictive variables such as the age of the respondents, current multiple pregnancy, and history of diabetes mellitus. Conclusion: The findings of this study showed that preeclampsia was present in a large proportion of women. For both urban and rural residents, health seeking actions towards pregnant women should be promoted, offering an opportunity to detect preeclampsia as early as possible and preventing the coming complication of preeclampsia. The role of antioxidants is controversial in the prevention of preeclampsia. Vitamin D deficiency is associated with preeclampsia in a major way. To document the role of vitamin D supplementation in the prevention of preeclampsia, further studies are required.  Keywords: Gestational hypertension, Pre-eclampsia, Vitamin D, GSH

The aim of this study was to investigate some aspects of the performance of electrochemical process as an alternative disinfection strategy, while minimising DBPs, for water purification. The study of electrochemical processes has shown free chlorine to be produced, but smaller amounts of stronger oxidants, such as ozone, hydrogen peroxide and OH radicals (•OH), were also generated. The formation of mixed oxidants increased with increasing electric conductivity, but was limited at conductivities greater than 0.6 mS/cm. Using several microorganisms, such as E. coli and MS2 bacteriophage, inactivation kinetic studies were performed. With the exception of free chlorine, the role of mixed oxidants, especially OH radicals, was investigated for enhancement of the inactivation rate. Additionally, the formation and reduction of DBPs was studied by monitoring the concentration of haloacetic acids (HAAs) during the process.
