Öğe Chronic immobilization stress induces anxiety-related behaviors and affects brain essential minerals in male rats(Hogrefe Ag-Hogrefe Ag Suisse, 2022) Sahin, Zafer; Ozkurkculer, Alpaslan; Kalkan, Omer Faruk; Ozkaya, Ahmet; Koc, Aynur; Koca, Raviye Ozen; Solak, HaticeAlterations of essential elements in the brain are associated with the pathophysiology of many neuropsychiatric disorders. It is known that chronic/overwhelming stress may cause some anxiety and/or depression. We aimed to investigate the effects of two different chronic immobilization stress protocols on anxiety-related behaviors and brain minerals. Adult male Wistar rats were divided into 3 groups as follows (n = 10/group): control, immobilization stress-1 (45 minutes daily for 7-day) and immobilization stress-2 (45 minutes twice a day for 7-day). Stress-related behaviors were evaluated by open field test and forced swimming test. In the immobilization stress-1 and immobilization stress-2 groups, percentage of time spent in the central area (6.38 +/- 0.41% and 6.28 +/- 1.03% respectively, p < 0.05) and rearing frequency (2.75 +/- 0.41 and 3.85 +/- 0.46, p < 0.01 and p < 0.05, respectively) were lower, latency to center area (49.11 +/- 5.87 s and 44.92 +/- 8.04 s, p < 0.01 and p < 0.01, respectively), were higher than the control group (8.65 +/- 0.49%, 5.37 +/- 0.44 and 15.3 +/- 3.32 s, respectively). In the immobilization stress-1 group, zinc (12.65 +/- 0.1 ppm, p < 0.001), magnesium (170.4 +/- 1.7 ppm, p < 0.005) and phosphate (2.76 +/- 0.1 ppm, p < 0.05) levels were lower than the control group (13.87 +/- 0.16 ppm, 179.31 +/- 1.87 ppm and 3.11 +/- 0.06 ppm, respectively). In the immobilization stress-2 group, magnesium (171.56 +/- 1.87 ppm, p < 0.05), phosphate (2.44 +/- 0.07 ppm, p < 0.001) levels were lower, and manganese (373.68 +/- 5.76 ppb, p < 0.001) and copper (2.79 +/- 0.15 ppm, p < 0.05) levels were higher than the control group (179.31 +/- 1.87 ppm, 3.11 +/- 0.06 ppm, 327.25 +/- 8.35 ppb and 2.45 +/- 0.05 ppm, respectively). Our results indicated that 7-day chronic immobilization stress increased anxiety-related behaviors in both stress groups. Zinc, magnesium, phosphate, copper and manganese levels were affected in the brain.Öğe Comparison of Fluoxetine and Sertraline in Treatment of Postoperative Depression(Wiley, 2018) Gormus, Z.

Isik Solak; Koca, Raviye Ozen; Gunes, Canan Eroglu; Kutlu, SelimDepression is a chronic, recurrent and life-threatening disease affecting approximately 15% of the world population. Depression is responsible for neuropathologies like decreased neurogenesis and increased dendritic atrophy. Antidepressant treatments increase hippocampal neurogenesis and neurotrophic factor expression. Based on this information, it was aimed to investigate effect of sertraline on depression in rats with chronic mild stress (CMS) model and to determine how it affects cell proliferation and hypothalamic peptide levels in hypothalamus. 56 adult male Wistar albino; control, depression(D), depression + sertraline, sertraline were divided into groups. Various stressors were applied to D for 30 days. Open field test (OFT) and forced swimming test (FST) were conducted to check whether the animals were depressed. On the 16th day osmotic minipump was placed subcutaneously and sertraline (10 mg/kg/day) was administered for 15 days. Behavior tests were done. Hypothalamic peptide gene expression levels were analyzed by quantitative RT-PCR. Statistical evaluations were made using ANOVA. It caused a decrease in the percentage of movement in the D and control groups in the OFT, an increase in the immobility time in the D group in the FST, and an increase in the swimming behavior in the DS group. Animals did not show any anxiological behavior based on the elevated plus maze test results. CMS caused a decrease in GLUT2 and NPY gene expression in the hypothalamus of animals, an increase in POMC and FGFR2, and an increase in IGFIR and GLUT2 gene expression in the DS group. Sertraline has been shown to ameliorate the effects of CMS-induced depression. Sertraline is thought to have a positive regulatory effect on both the formation of neural precursor cells and the survival of newly formed neurons in the hypothalamus. Newly formed neurons in the hypothalamus express food intake-related NPY, POMC, GLUT2 neurons, and thus hypothalamic tanycytes may play a key role in the control of energy metabolism.Öğe Effect of Apelin on Anxiety Like Behaviour in Male Rats(Karger, 2021) Sak, Zeynep Caliskan; Kutlu, Selim; Ozkurkculer, Alpaslan; Koca, Raviye Ozen; Solak, Hatice; Gormus, Zisik Solak[Abstract Not Availabe]Öğe Effect of Intravenous Glucose Administration on Catecholamine Concentrations in Hypothalamic Ventromedial Nucleus in Rats: A Microdialysis Study(Wiley-Blackwell, 2016) Solak, Hatice; Koca, Raviye Ozen; Gormus, Z.

Method: Thirty-two adult male Wistar albino rats, weighing between 300-350 g, were randomly divided into four groups (Control, Agomelatine, Fluoxetine, Sertraline). After cervical dislocation, the bladders were promptly removed, cut into 3-4-millimeter strips, and suspended in an isolated organ bath at a tension of 1 gram. Contractions were induced by acetylcholine (ACh) at a concentration of 10(-5) M. Cumulative doses of agomelatine, fluoxetine, and sertraline (ranging from 10(-8) to 10(-3) M) were administered to the organ bath chambers. The least squares means were compared using the Tukey-Kramer post-hoc test to compare the tension values of the groups at different time points.Results: The inhibition of rat bladder contractions was statistically significant at agomelatine doses of 10(-7) M (p=0.0413), 10(-6) M (p=0.033), 10(-5)M (p=0.003), and 10(-4) M (p<0.001), with a statistically significant recontraction response noticed after the agomelatine dose of 10(-3) M (p<0.001). Cumulative fluoxetine doses at 10(-7) M (p=0.0182), 10(-6) M (p=0.0012), and 10(-5), 10(-4), 10(-3) M (all at p<0.001), along with sertraline doses at 10(-5) M (p=0.0096), 10(-4) M (p=0.001), and 10(-3) M (p<0.001), also significantly inhibited contraction. Conclusion: Agomelatine, fluoxetine, and sertraline were found to exhibit inhibitory effects on bladder contraction in a dose-dependent manner.Öğe The effects of agomelatine, fluoxetine, and sertraline on rat bladder contraction in vitro(Kare Publ, 2023) Gormus, Zulfikare Isik Solak; Vidin, Tuba; Koca, Raviye Ozen; Solak, Hatice; Uslu, Esra FidanObjective: This study aimed to determine the potential effects of three popular antidepressants: agomelatine, fluoxetine, and sertraline on in vitro rat bladder contraction responses, and to investigate their contribution to overactive bladder syndrome.
