    Typical and atypical antipsychotic drugs are widely used to treat psychosis. The present study investigated whether ziprasidone, an atypical antipsychotic drug, has a neuroprotective effect on hippocampal neurons in rats with experimentallyinduced transient cerebral ischemia comparatively with haloperidol which is a typical antipsychotic. Transient cerebral ischemia was induced by 10-minute occlusion of bilateral carotis communis arteries. The rats were divided into four groups: Shamoperated control group (Group I), ischemia control group (Group II), haloperidol-treated group (Group III) and ziprasidone-treated group (Group IV). Following 10-minute ischemia, Group III received 1mg/kg haloperidol intramuscularly and Group IV received 2.5 mg/kg ziprasidone intraperitoneally. The animals were sacrificed on the seventh day following induced ischemia to determine the number of intact neurons at hippocampus and dentate gyrus to demonstrate the effects of ischemia and efficacy of the treatments administered. Surviving cell numbers were found in the sham operated group; 198, in the ischemia control group; 80, in the haloperidol-treated group; 185, in ziprasidonetreated group; 189. The groups showed significant difference in the comparison of the surviving cell numbers. However, the number of surviving cells did not significantly different between the ziprasidone and haloperidol-treated group. Previous studies with the ischemia model have demonstrated protective effects of haloperidol on hippocampal region. The findings of the present study show that ziprasidone, which is an atypical antipsychotic drug, may produce neuroprotective effects as potent as haloperidol, which is a typical antipsychotic drug. © 2014 OMU.

    Solitary cerebellar metastasis from a non-muscle invasive transitional cell carcinoma of bladder [Transisyonel hücreli yüzeyel invaziv mesane kanserinin serebelluma soliter metastazı]
    (Ege University Press, 2015) Kelten B.; Ekici S.; Erdoğan H.; Sinanoğlu O.; Yener N.; Karaoğlan A.
    Brain metastasis from non muscle invasive transitional cell carcinoma of the urinary bladder occurs very rarely. Herein, a patient who underwent transurethral resection of bladder tumor and received intravesical bacillus Calmette- Guérin for pT1, G3 bladder carcinoma accompanied by carcinoma in situ, and who subsequently developed solitary cerebellar metastasis following 18 months cystoscopic follow up period with normal findings was reported. To our knowledge, only two cases of solitary cerebellar metastasis from pT1 bladder cancer was reported in the English literature. © 2015, Ege University Press. All rights reserved.
