    Impairment of Glucose Tolerance Test During Pregnancy and Serum Assymmetric Dimethylarginine Levels
    (Derman Medical Publ, 2016) Findik, Rahime Bedir; Celik, Huseyin Tugrul; Yilmaz, Fatma Meric; Yilmaz, Hinc; Abusoglu, Sedat
    Aim: Assymetric dimethylarginin (ADMA), an inhibitor of nitric oxide synthase (NOS), has been linked to endothelial dysfunction. Our aim in this study was to compare ADMA and arginine levels in normal glucose tolerance, impaired glucose tolerance and gestational diabetes groups and investigate the effect on baby birth weight. Material and Method: Serum ADMA and arginine levels were investigated in 64 patients whose 50-g glucose loading test was normal (group 1, NGT); 33 patients whose 50-g test result was high and those whose 100-g oral glucose tolerance test (OGTT) was normal, namely, those with impaired glucose tolerance (IGT, group 2); and in 8 patients diagnosed with gestational diabetes mellitus (GDM, group 3). Results: Arginine levels were significantly higher in the IGT group than in the NGT group. ADMA levels were high in the GDM group, but the difference was not statistically significant. There were a statistically significant correlation between arginine and ADMA levels and the ADMA level of those with a diabetes history. No significant relationship was found between ADMA level, arginine and the weight of the infant. Discussions: Although there has not been a clinical status related with nitric oxide deficiency caused by increasing ADMA concentrations, pregnancies with increased body mass indeks (BMI), family history for diabetes and older ages should be carefully monitorized. ADMA tends to increase in patients with IGT and GDM. In addition, blood ADMA and arginine levels do not seem to influence the weight of the infant.

    Mercury concentration in maternal serum, cord blood, and placenta in patients with amalgam dental fillings: effects on fetal biometric measurements
    (Taylor & Francis Ltd, 2016) Findik, Rahime Bedir; Celik, Huseyin Tugrul; Ersoy, Ali Ozgur; Tasci, Yasemin; Moraloglu, Ozlem; Karakaya, Jale
    Aim: We aimed to determine the extent to which mercury is transmitted from the mother to fetus via the umbilical cord in patients with amalgam dental fillings, and its effect on fetal biometric measurements.Methods: Twenty-eight patients as the study group with amalgam fillings, and 32 of them as the control group were included in this prospective case-control study. The mercury levels were measured in the maternal and cord venous sera, and the placental samples. Two groups were compared in terms of these and the fetal/neonatal biometric measurements.Results: In the study group, the maternal and umbilical cord mercury levels were found to be significantly higher than those from the control group (p=0.006 and p=0.010, respectively). These high levels did not affect the fetal biometric measurements.Conclusions: The presence of high serum mercury levels in pregnant women with amalgam fillings is important, and warrants further long-term studies in order to investigate the fetal neurological effects as well.
