[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to examine the association of factor V Leiden, prothrombin and methylenetetrahydrofolate reductase (MTHFR) polymorphisms and preeclampsia (PE) in Southeast of Iran.
This case-control study was performed on 192 preeclamptic and 196 normotensive pregnant women. Single nucleotide polymorphisms were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and Tetra ARMS methods.
No significant differences were observed in distribution of MTHFR C677T and FVL polymorphisms between two groups. There was a significant difference in frequency of 1298AC genotype in PE pregnant women compared to controls (P = 0.03). No 20210A allele of prothrombin gene was observed in this population. The analysis of MTHFR and factor V Leiden polymorphisms between early-onset PE (EOPE) and late-onset PE (LOPE) showed significant differences in MTHFR A1298C polymorphism (AC and CC vs AA, P = 0.012 and P = 0.006, respectively) and G1691A polymorphism of FVL(GA vs GG, P = 0.03). Moreover, the analysis of three SNPs between EOPE and controls showed significant differences in MTHFR C677T (CT + TT vs CC, P = 0.035) and MTHFR A1298C (AC and CC vs AA, P = 0.001 and P = 0.006, respectively) polymorphisms. The synergic effect of MTHFR A1298C and C677T polymorphisms showed increased risk of EOPE.
MTHFR A1298C polymorphism was associated with PE. Although MTHFR C677T and FVL polymorphisms did not differ between PE patients and controls, significant differences in MTHFR A1298C, C677T and FVL polymorphisms between EOPE and LOPE/controls were observed. The synergic effect of MTHFR variants could increase PE and EOPE risk.

[Show abstract][Hide abstract] ABSTRACT: Aim:
This study was designed to clarify the role of leptin and adiponectin in preeclampsia (PE) pathogenesis and different subtypes of preeclampsia.
This case control study was performed in 45 PE patients and 45 healthy controls matched for age, BMI, and ethnicity. Serum leptin and adiponectin levels were determined by enzyme linked immunosorbent assay (ELISA).
Maternal serum leptin and adiponectin were significantly higher in PE women than controls. Serum leptin was elevated in early onset preeclampsia (EOPE) and late onset preeclampsia (LOPE) compared to controls. Among PE patients, serum leptin was higher in EOPE than LOPE women. However, serum adiponectin was not different between EOPE and LOPE women. The serum leptin was significantly higher in severe PE than mild PE. The serum adiponectin was significantly elevated in severe PE compared to controls. Significant positive correlation was observed between leptin and adiponectin and also between leptin and BMI in controls. Moreover significant positive correlation was observed between adiponectin and BMI in PE patients and controls.
The present study showed that serum leptin level may play a significant role as a biomarker to differentiate early and late onset PE and also its relation to BMI and severity of disease.
[Show abstract][Hide abstract] ABSTRACT: Preeclampsia (PE) is the most serious complication of pregnancy that causes maternal and fetal morbidity and mortality. Although the exact pathophysiology of PE is unknown, a large number of studies have shown that abnormalities in nitric oxide (NO) synthesis may contribute to the development of this disorder. There are some evidences that polymorphisms of the endothelial nitric oxide synthase (eNOS) gene affect NO production and have been associated with hypertension and PE in some populations. Therefore the aim of this study was to assess the relation of the Glu298Asp eNOS polymorphism and PE in an Iranian population. We compared the frequency of the Glu298Asp polymorphism in 147 women with PE and 137 healthy pregnant control subjects by polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP) method. The frequencies of Glu298Asp genotypes were significantly different between PE women and controls (p < 0.001). The frequency of Asp allele was 0.32 in PE patients and 0.20 in controls and was significantly different (p < 0.001). The risk of PE was 2.4 fold in pregnant women with Asp allele. In conclusion, the Asp allele could be a risk factor for PE in South East of Iran.

[Show abstract][Hide abstract] ABSTRACT: In traditional medicine, Eucalyptus globulus (eucalyptus) was used for the treatment of diabetes mellitus. Hyperglycemia in diabetes has been associated with increased formation of reactive oxygen species (ROS) and oxidative damage to tissue compounds. The aim of this study was to evaluate the effects of eucalyptus in the diet (20 g/Kg) and drinking water (2.5 g/L) on lipid peroxidation, protein oxidation and antioxidant power in plasma and liver homogenate, as well as glycated-Hb (HbA(1C)) of blood in streptozotocin-induced diabetic rats for a period of 4 weeks. Diabetes induced in rats by a single intraperitoneal injection of streptozotocin (STZ, 65 mg/Kg). At the end of the treatment period, the level of plasma glucose, plasma and liver malondialdehyde (MDA, the main product of lipid peroxidation), protein carbonyl (PC, one of the protein oxidation products) and HbA(1C) increased and ferric reducing antioxidant power (FRAP) decreased in diabetic rats compared to normal rats. Eucalyptus administration for 4 weeks caused a significant decrease in the plasma glucose levels, plasma and liver MDA, PC and HbA(1C), also a concomitant increase in the levels of FRAP in diabetic treated rats. In conclusion, the present study showed that eucalyptus posses antioxidant activities. Eucalyptus probably restores antioxidant power, due to the improved hyperglycemia in streptozotocin-induced diabetic rats.
