Abstract

Background Pre-eclampsia is a serious hypertensive condition of pregnancy associated with high maternal and fetal morbidity and mortality. Women who have had pre-eclampsia have a greater risk of developing hypertension, stroke and ischemic heart disease in later life. The etiology of pre-eclampsia remains unclear. Placental insufficiency plays a key role in the progression of this disease. The aim of this study was to determine membrane potential, serum calcium and serum selenium levels in preeclampsia subjects in Owerri. MethodsA case control study involving 200 primigravida (100 preeclamptic and 100 apparently healthy) between the ages of 20 and 32 years attending General Hospital Owerri. Fasting venous blood was collected for the determination of serum selenium and serum calcium while membrane potential was calculated using the Nernst equation. The serum calcium was estimated using Randox Kit and serum selenium by atomic absorption spectrophotometry. The Independent Student t test was used for statistical analysis. ResultsThe results revealed that membrane potential and serum selenium as well as serum calcium were significantly decreased in preeclampsia when compared with the controls, at p<0.05. ConclusionOur study demonstrated that the decrease in membrane potential, serum calcium and serum selenium levels may play a critical role in the pathogenesis of pre-eclampsia. There may be a need for increasing the dietary intake of these essential trace metals during pregnancy to prevent pre-eclampsia in Owerri.

Abstract

BackgroundPreeclampsia is a major cause of maternal and fetal morbidity and mortality. The imbalance of anti-angiogenic and angiogenic factors plays a role in endothelial dysfunction in preeclampsia. L-arginine is expected to improve the process of spiral artery remodeling. This study aims to examine the use of L-arginine to repair endothelial damage by measuring the thickness of uterine spiral arteries in mouse (Mus musculus) models of preeclampsia.MethodsThe researchers carried out an experimental study using 30 sixteen-day old pregnant Swiss mice (in good health, weighing 20-25 grams), which were randomly divided into 3 groups (each consisting of 10 mice). The groups were as follows: 1) normal pregnancy K(-); 2) preeclampsia model K(+); and 3) preeclampsia model receiving L-arginine (P). The authors performed histopathological examination of the mouse placenta, which had been dissected, embedded in paraffin wax and subsequently stained with hematoxylin and eosin (HE). The results were analyzed in SPSS v. 21 for Windows using Anova with Tukey.ResultsThe mean thickness of spiral arteries in group K(-) was 53.95 + 26.96 mm, in K(+) 96.50 + 16.66 mm, and in P 62.79 + 8.04 mm. Statistically, there were significant differences between groups K(-) and K(+) (p=0.001) and between K(+) and P (p=0.000), but non-significant differences between K(-) and P (p=1.000).ConclusionsThe treatment with L-arginine proved to be effective in repairing endothelial damage by reducing intimal hyperplasia and atherosis and, in turn, the thickness of uterine spiral arteries in mouse models of preeclampsia.

Abstract

BackgroundThe decline in estrogens could lead to an imbalance of bone formation and absorption as well as bone mineralization. Phytoestrogens are known to have the potential to maintain bone health. Calcium and phosphorus are essential components for bone mineralization. This study aimed to investigate the effect of soybean sprout flour consumption on serum calcium and phosphorus levels in ovariectomized rats.MethodsA randomized post-test-only control group design involving 25 female Sprague-Dawley rats aged 2 months, which were divided into five groups: (i) normal controls on standard feed diet AIN-93 (C-N), (ii) ovariectomy controls on standard feed diet (OVX -N); (iii) ovariectomized rats on standard feed diet + ethinylestradiol (OVX -E), (iv) ovariectomized rats on standard feed diet + soybean flour (OVX -S); (v) ovariectomized rats on standard feed diet + soybean sprout flour (OVX -SS). The rats were treated for 6 weeks, then on the last day of treatment blood sampling was conducted. Analysis of calcium and phosphorus in serum was performed using the Arsenazo III photometric method. Data were analyzed using one-way Anova.ResultsMean serum calcium level was highest in the OVX-SS group (12.59 mg/dL ± 1.32), while mean serum phosphorus level was highest in the C-N group (1.708 mg/dL ± 0.28). Soybean sprout flour consumption had a significant effect on serum calcium levels (p=0.019), yet it had no effect on body weight and serum phosphorus levels of the rats.ConclusionConsumption of soybean sprout flour could positively affect serum calcium levels in rats.

Abstract

BackgroundIn Indonesia, cancer prevalence according to the Basic Health Research 2013 was 1.4 per 1000 inhabitants and the most common cancer in hospitalized patients in 2010 was breast cancer (28.7%). Hormonal contraception (HC) use increases the breast cancer risk, even though HC has been used by 210 million women in the world. We aimed to define the association of HC with breast tumors based on clinical breast examination (CBE).MethodsA case-control design using secondary data from the baseline of the Cohort Study on the Risk Factors of Non-Communicable Disease (RFNCD) in 2011-2012 in 5 villages in Central Bogor District, Bogor City. Samples consisted of 152 cases and 152 controls. Cases comprised palpable tumors in one or both breasts CBE (+). Controls had no tumors in both breasts /CBE(-). Data were analyzed by logistic regression.ResultsOdds Ratio (OR) of CBE + was 1.83 (95% CI: 1.11-3.04; p=0.019) for HC user and 1.62 (95% CI: 1.01-2.60; p=0.044) for blood total cholesterol level <200 mg/dL. OR of group CBE(+) was 1.01 (current smoking) and 0.49 (former smoking) compared with nonsmoking (p=0.082); OR was also 1.21 for subjects with one child and 1.77 for those without children, compared with those who had ³2 children (p=0.454).Conclusion Hormonal contraception use increases breast tumor risk 1.8-fold after controlling for total cholesterol, smoking status and parity. With the several limitations of this advanced analysis, investigations focused on types and duration of HC use are still necessary.
