ABSTRACT
Background: Preeclampsia is a disease with a variety of theories that describe the uncertainty of the pathophysiology. According to the oxidative stress theory, preeclampsia originates from the failure of trophoblast invasion during the implantation process, causing ischemia and placental hypoxia, which in turn causes cell damage, including placental endothelial cell dysfunction. Omega-3 fatty acids and vitamin E have an important role in preventing preeclampsia. Omega-3 fatty acids play an important role in maintaining cell membranes and anti-inflammatory processes. At the same time, vitamin E acts as a fat-soluble antioxidant that can prevent oxidative stress, inhibit proinflammatory cytokines, and protect fatty acids from oxidation. Aim: The purpose of this study was to determine the effect of omega-3 and vitamin E on the level of ROS and NO in pregnant rats with preeclampsia models.
Method & Material: This type of research is experimental with Post-Test Only Control Group Design. The sample consisted of 35 pregnant rats, which were divided into five groups. On the 19th day, blood serum was taken to check the levels of ROS and NO. The measuring instrument used is a spectrophotometer with the ELISA method. Data were analyzed using the Shapiro Wilks normality test. After the parametric test was completed, the hypothesis was tested using one-way ANOVA.
Results: The average levels of ROS in each group were K- : 121,684 ng/L, K+ : 143,885 ng/L, P1 : 136,250 ng/L, P2 : 132.433 ng/L, and P3 : 122,993 ng/L. The average levels of NO obtained were K-: 29,502 ng/L, K+: 26,053 ng/L, P1: 27,250 ng/L, P2: 27,555 ng/L, and P3: 32,278 ng/L. The results of one-way ANOVA analysis showed that the administration of omega-3 and vitamin E had a significant difference between the control and treatment groups, both at levels of ROS (p=0.001) and levels of NO (p=0.001).
Conclusion: The administration of omega-3, vitamin E, and omega-3 plus vitamin E can reduce ROS levels in pregnant rats with preeclampsia models. There is an increase of NO levels only in the administration of omega-3 plus vitamin E.
