    Evaluation of erythropoietin effects on cerebral ischemia in rats
    (Maghira and Maas Publications, 2007) Aluclu M.U.; Acar A.; Guzel A.; Bahceci S.; Yaldiz M.
    Objective: Majority of severe disabilities in adults are caused by stroke. The aim of our study is to learn the effects of erythropoietin (EPO), on infarct size in cerebral ischemia and to determine neurological behavioral scores and histopathological evaluation. Material & methods: In this study 30 adult Sprague-Dawney rats were used. Cerebral ischemia was constituted by intraluminal filament method with a 4-0-nylon suture. Reperfusion was started after two hours of middle cerebral artery occlusion. The rats were randomly divided into two groups as follow: control and EPO groups. Saline 0.9% (0.6 m5 ml/kg) and EPO (5 000 U/kg) was administered intraperitoneally in the groups. Three coronal slices in two millimeters thickness were obtained from cerebrum, cerebellum and brain stem, and were stained with a 2% solution of triphenyltetrazolium chloride. Transparent sheets were placed over each section and the areas of the brain and infarct were measured. The neurological scores were determined at 24th, 48th and 72nd hours after reperfusion. Results: Percent of ischemic area (%) in cerebrum, cerebellum and brain stem level in EPO groups were less than those of control group (p<0.0001). In addition, we determined that EPO group was better than controls of neurologic score and histopatologically after cerebral ischemia. Conclusions: We concluded that EPO may decrease ischemic area in experimental cerebral ischemia in rats and it seems that EPO may be beneficial. © 2007 Neuroendocrinology Letters.

    A rare embryological malformation of brain - Dandy-Walker syndrome - And its association with Kallman's syndrome
    (Maghira and Maas Publications, 2007) Aluclu M.U.; Bahceci S.; Bahceci M.
    Background & aim: Dandy-Walker malformation, a rare congenital brain malformation, is described as a triad of cystic dilatation of the fourth ventricle, complete or partial agenesis of the cerebellar vermis, and an enlarged posterior fossa with elevated tentorium. We aimed to report an association of Kallmann's syndrome and Dandy-Walker malformation. Case: A fifteen years old boy was referred to endocrinology department due to delayed puberty. Stages of male genital development according to Marshall and Tanner, was stage G1 and P1 respectively. In the LHRH test, peak LH level was 40th min.: 15.3 IU/ml. Peak growth hormone with insulin tolerance test was 14.5 ?g/L. Olfactory test revealed light anosmia. With these findings the patient was accepted as isolated gonadotropin deficiency (Kalmann's syndrome). In computed tomography of the brain, cerebellar vermis was found to be hypoplastic and 4th ventricle was large and in posterior fossa broad hypodens area with cerebrospinal fluid density were seen (Dandy-Walker malformation). Conclusion: We reported an association of Kallmann's syndrome and Dandy-Walker malformation. This is second reported case pobably. © 2007 Neuroendocrinology Letters.
