    Effects of antioxidant vitamins A, C, E and trace elements Cu, Se on CuZnSOD, GSH-Px, CAT and LPO levels in chicken erythrocytes
    Aydemir, T; Öztürk, R; Bozkaya, LA; Tarhan, L
    The biologically damaging effects of reactive oxygen species are controlled in vivo by a wide spectrum of antioxidant defence mechanisms. Dietary constituents of antioxidant vitamins and trace elements may play an important role in protecting against oxidant damage. The effects of supplementation of vitamins A, C, E and trace elements Cu and Se on the activities of antioxidant enzymes and lipid peroxide levels in chicken erythrocytes were investigated depend on the time. CuZnSOD activity and plasma Cu levels in the Cu group were increased by 39 and 37 per cent respectively. CuZnSOD activity in vitamin C groups was also increased by 20 per cent. The GSH-Px activity in Se, Se + E and Se + Ca groups was raised by 35, 46 and 69 per cent respectively. Also, the GSH-Px activity in the vitamin C group was increased by 33 per cent. Catalase activity in all of these groups was not significantly different when compared with controls (p < 0.01). The maximum decrease in LFO levels of 42 per cent was obtained for the Se + E group.

    Comparing psychological symptoms in hyperemesis gravidarum and healthy pregnancies: a case-control study
    Güleç, D; Öztürk, R; Sen, S; Güneri, SE
    The aim of this study was to compare psychological symptom of pregnants who were diagnosed with hyperemesis gravidarum and had healthy pregnancy. Research was a case-control study which included 97 first trimester pregnant women. 40 pregnant women hospitalized for hyperemesis gravidarum and 57 healthy pregnant women were included in to the study as a control group. Groups were matched in terms of age, parity and gestational age and year of marriage. Questionnaire Form and The Brief Symptom Inventory were used for collecting the data. As a result of study The Brief Symptom Inventory total score and 'depression', 'anxiety', 'somatization' and 'hostility' subscale total scores were found statistically higher than healthy pregnants (P<0.05). Pregnant women with hyperemesis gravidarum experience more problems such as depression, anxiety, somatization and hostility than healthy pregnant women. Evaluating of presence of psychological symptoms and giving suitable care while this women take nursing care to is very important both pregnant and fetus health.

    Normative values of the balloon expulsion test in healthy adults
    Dedeli, Ö; Turan, I; Öztürk, R; Bor, S
    Background/aims: Constipation is the most frequent complaint of the digestive tract. It has been reported that approximately half of the patients with constipation have functional defecation disorders (dyssynergic defecation). An important diagnostic tool for the diagnosis of functional defecation disorders is the balloon expulsion test. Normative values have not been widely determined in different populations. We aimed to determine the data which could be indicative of normative values of the balloon expulsion test for healthy individuals in our society. Methods: A total of 116 healthy volunteers were evaluated in. the study (55 men). Subjects were classified into three subgroups according to age (20-39 yrs, 40-59 yrs, >= 60 yrs). Catheters with balloon and application room were standardized, and then a balloon expulsion test was performed in all groups. The results of the balloon expulsion test were statistically compared between groups. Results: The distribution of males/females according to age groups was: 20-39 yrs: 20/22, 40-59 yrs: 20/23, >= 60 yrs: 15/16. The balloon expulsion time was determined as 44.1 +/- 19.0 seconds in male subjects and 56.4 +/- 21.4 seconds in females (p=0.001). An increase in the balloon expulsion time was observed to be related with age in males (p=0.00001); however, no statistically significant difference was shown by age in female subjects (p=0.80). If the entire study group was considered, there was a significant correlation between age and balloon expulsion time (p=0.0001). Conclusions: The balloon expulsion test is a simple procedure to identify impaired evacuation in constipated patients. This study represents the first assessment of the balloon expulsion test in a healthy Turkish population. It has been demonstrated that expulsion should take less than 30 seconds for men younger than 40 years of age and less than 1 minute above 40 years. For women, expulsion should occur in I minute regardless of age. Our results could serve as a valuable resource of normative data.
