Introduction. This article investigated the role of oxidative stress in the etiology of pregnancy induced hypertension. The aim of this study was to determine the degree of oxidative stress, and the level of thiobarbituric acid reactive substance in the blood of pregnant women with and without pregnancy induced hypertension and to correlate these parameters with clinical parameters during pregnancy and delivery. Material and Methods. This prospective study was performed at the University Clinical Centre of the Republic of Srpska. It included 200 pregnant women - 100 with pregnancy induced hypertension, and 100 healthy normotensive pregnant women between 28 to 40 weeks of gestation. Results. Pregnant women with pregnancy induced hypertension had significantly higher median levels of oxidative stress marker: thiobarbituric acid reactive substance of 36.7 ?mol compared to the control group of 13.2 ?mol. Pregnant women with pregnancy induced hypertension presenting with complications had significantly higher thiobarbituric acid reactive substance mean levels of 41.6 ?mol compared with pregnant women without complications. The highest thiobarbituric acid reactive substance level of 43.9 ?mol was found in pregnant women with Hemolysis, Elevated, Liver Ensimes, Low Plateles syndrome. Conclusion. The study showed that thiobarbituric acid reactive substance, as an oxidative stress marker, may be used in clinical practice in the assessment of the severity of complications and as an indicator for timely delivery in women with pregnancy induced hypertension. Further studies and a larger study sample of pregnant women with severe hypertension are necessary to confirm this conclusion.

Aim. To investigate the role of a novel oxidative stress marker, thiol/disulphide homeostasis, in patients diagnosed with acute appendicitis (AA).Methods. In this study, seventy-one (43 male and 28 female) patients diagnosed with AA and 71 (30 male and 41 female) healthy volunteers were included. Age, gender, body mass index (BMI), haemoglobin (Hb), white blood cell (WBC), c-reactive protein (CRP), and thiol/disulphide homeostasis parameters (native thiol, total thiol, disulphide, disulphide/native thiol, native thiol/total thiol, and disulphide/total thiol ratios) were compared between the groups. Thiol/disulphide homeostasis was determined by a newly developed method by Erel and Neselioglu.Results. The native thiol, total thiol, and the native thiol/total thiol ratio levels were statistically significantly decreased in the AA compared with the control group (p<0.001). Disulphide level and the ratios of disulphide/native thiol and disulphide/total thiol were higher in the AA group than in the control group (p<0.001). There was a negative correlation of CRP with native thiol, total thiol, and native thiol/total thiol ratio while there was a positive correlation of CRP with disulphide/native thiol and disulphide/total thiol in the AA group. In the stepwise regression model, risk factors as disulphide/native thiol (OR = 1.368;p=0.018) and CRP (OR = 1.635;p=0.003) were determined as predictors of perforated appendicitis compared to the nonperforated group.Conclusion. This is the first study examining the thiol/disulphide homeostasis as a diagnostic aid in AA and establishing thiol/disulphide homeostatis balance shifted towards the disulphide formation due to thiol oxidation. Further studies are needed to optimize the use of this novel oxidative stress marker in AA.

Alkaloid Fraction

A disruption in the equilibrium between the generation of reactive oxygen species and antioxidant defense enzymes is referred to as oxidative stress. In the present study, we planned to identify the hepatoprotective effect of Phyllanthus amarus alkaloid rich fraction in wistar strain albino male rats. The hepatic damage was induced by the D-galactosamine and ameliorative effect was tested with alkaloid rich fraction of P. amarus by measuring oxidative stress markers such as G6PDH, LDH, SDH, MDH and GDH in the liver tissue. Activity levels of G6PDH, SDH, MDH and GDH were significantly decreased in D-galactosamine induced hepatitis rats when compare to normal control rat group, while their activities were significantly increased in hepatitis rat group that supplemented with alkaloid rich fraction of P. amarus. In contrast, LDH enzyme activity of liver was significantly increased in the hepatitis rat group when compare to normal control rats, while its activity was significantly decreased in hepatitis rats treated with alkaloid fraction. In conclusion, it is very clear that alkaloid fraction of P. amarus has hepatoprotective property with respect of decreasing oxidative stress by regulating oxidative stress marker enzymes. The isolation and identification of specific alkaloid compounds with hepatoprotective properties and anti-oxidative stress will require much further research.

Background: PCOS is a condition with significant decrease in antioxidant with an increased risk of oxidative stress. Antioxidant supplementation has been shown to improve insulin sensitivity in PCOS and may improve outcome of management of PCOS. Objectives of this study were to determine the oxidative stress level of PCOS patients, to assess the effect of antioxidant supplementation on the outcome of management of PCOS and to compare with a control group.Methods: The study was a single blind randomised control trial involving 200 patients with PCOS. The study was conducted at Usmanu Danfodiyo University Teaching Hospital Sokoto. They were randomly divided into intervention and control groups and base line serum levels of oxidative stress marker, antioxidant enzymes, vitamins and minerals were determined. Antioxidant supplementation and placebo were given to the intervention and control groups respectively. All the patients had ovulation induction with clomiphene citrate and were followed up for 6 months. Outcome measures were clinical pregnancy or menstrual regularisation. Level of significance was <0.05.Results: There was statistical significance in the serum levels of oxidative stress marker, antioxidant enzymes, vitamins and minerals between the two groups (post intervention). Glutathione peroxidase (p = 0.001), superoxide dismutase (p = 0.0001), catalase (p= 0.0369), melondialdehyde (p= 0.007), Vitamin A, Vitamin C, Vitamin E (p = 0.0001), zinc and copper (p = 0.0001). The clinical pregnancy outcomes were 22 (22%) versus 2 (2%); live births 18 (18%) versus 2 (2%) and menstrual regularisation 48 (48%) versus 46 (46%) in the intervention and control groups respectively.Conclusions: Antioxidant supplementation in this study significantly affected pregnancy rate in patients with PCOS. Larger studies are suggested to revisit the conclusion of the Cochrane review that antioxidants supplementation had no significant role in female infertility.
