The role of carcinoembryonic antigen (CEA) in Parkinson's disease (PD) has not been previously investigated. The aim of the present study was to evaluate the serum level of carcinoembryonic antigen, high-sensitivity C-reactive protein (hs-CRP), and Neutrophil/lymphocyte ratio (NLR) among patients with Parkinson's disease and to examine the relationship between these inflammatory markers. The cross-sectional design includes 51 patients with Parkinson's disease and 50 age- and sex-matched healthy controls. We investigated the differences in hs-CRP, CEA, and NLR levels between these two groups. CEA was significantly higher in PD patients relative to the control group (mean 2.40 ± 1.51 vs. 1.72 ± 0.87 (ng/mL), respectively; p = 0.015). Mean NLR was significantly higher in PD patients relative to the control group (mean 3.1 ± 1.3 vs. 2.1 ± 0.32, respectively; p < 0.001). Serum level of hs-CRP was higher in PD patients than in control group (mean 1.04 ± 0.62 and 0.54 ± 0.31, respectively; p < 0.01). Correlation analysis revealed significant correlation between hs-CRP, CEA, and Neutrophil/lymphocyte ratio (p < 0.05). This study demonstrates for the first time the association between CEA, hs-CRP, NLR, and PD. We found CEA, hs-CRP, and NLR levels to be significantly higher in the PD patients than in the normal controls.

Balo’s concentric sclerosis (BCS) is a rare monophasic demyelinating disease known as multiple sclerosis subtype and seen as a round lesion with variable hyper and hypo-detoxification layers. Characteristic appearance can be seen as “bulb eye” or “onion bulb”. The initial terminology for this neurological disorder was leukoencephalitis periaxialis concentrica; this is defined as a disease in which the white matter of the brain is destroyed in concentric layers in such a way as to leave the axial cylinders intact. This report presents a case of BCS with spontaneous healing of the patient and a mass lesion with concentric rings adjacent to the left lateral ventricle and the posterior portion of the corpus callosum with peripheral vasogenic edema. The neurological lesion of the patient was similar to the magnetic resonance imaging and clinical findings of the BCS.

ObjectiveMigraine, a highly prevelant headache disorder, is regarded as a polygenic multifactorial disease. Serotonin (5-HT) and their respective receptors have been implicated in the patogenesis.MethodsWe investigated the 5-HT1A, 5-HT1B, 5-HT2A, and 5-HT2C receptor gene polymorphisms and their association with migraine in Turkish patients. The rs6295, rs1300060, rs1228814, rs6311, rs6313, rs6314, rs6318, rs3813929 (−759C/T) and rs518147 polymorphisms were analyzed in 135 patients with migraine and 139 healthy subjects, using a BioMark 96.96 dynamic array system.ResultsWe found no difference in the frequency of the analyzed eight out of nine polymorpisms between migraine and control groups. However, a significant association was found between the rs3813929 polymorphism in the promoter region of 5-HTR2C gene and migraine. Also, the allele of rs3813929 was more common in the migraine group.ConclusionThis result suggests that the 5-HTR2C rs3813929 polymorphism can be a genetic risk factor for migraine in a Turkish population.

Stroke is one of the major reasons of death in the United States and related to adult disability. Despite aggressive research, the treatment approaches of stroke still remains a major clinical problem. Intravenous immunoglobulin (IVIg) is a polyspecific Ig G preparation obtained from plasma of several thousand healthy people (donors). IVIg is an important treatment approach and used for several disorders. The aim of this study was to investigate the potentially beneficial effects of IVIg therapy in experimentally induced ischemia in middle cerebral artery occlusion (MCAo) models of rats. A total of 30 adult male Sprague Dawley rats were used. The rats were divided into two equal groups, each consisting of 15 randomly selected rats: control group (n = 15) and IVIg group (n = 15). Intraluminal filament method was used for establishment of cerebral ischemia. Intraluminal filament was withdrawn after 2 h of MCAo and reperfusion started again and passed to therapeutic stages for all the groups. Physiologic saline solution of 0.5 ml/kg was administered to the control group and 400 mg/kg IVIg was given to the IVIg group rats intravenously. In neurological evaluation, the worst score was determined as 3 and the best score as 0. After routine process, the brain tissue was prepared histopathological investigation. The IVIg group showed significantly better recovery with respect to the control group by neurological examination. The observation of specimens obtained from IVIg groups showed that findings correlate with grade 1 and -2 histopathologically. Nevertheless, ischemic amendments were observed to comply with grade 3 in ischemic areas in control group. IVIg therapy can be used in the treatment of ischemic stroke patients.

SUMMARY:We aimed to investigate the potential harmful effects of maternal valproic acid (VPA) on fetal sciatic nerve, and the protective effects of vitamin E (Vit E) and folic acid (FA) on fetal rats. Valproic acid (400mg/kg), folic acid (400mg/kg) and vitamin E (250 mg/kg) were administered to rats on each of gestation days 8-10. All fetuses were collected on gestation day 20. With thin sections of biopsies, sciatic nerve of fetuses were stained with uranyl acetat and were examined under transmission electron microscope. The fetuses (n:36) were divided into five groups: control, vpa, vpa+fa, vpa+vit e and vpa+fa+vit e groups. In each group; drug procedure, surgical procedure and histological methods were performed. Later, weights and lengths of fetuses in each group were compared and analyzed by One-Way Anova test. Administration of single doses of valproic acid (400 mg/kg) resulted in weight and length loss between control and vpa group. However, length and weight differences between the other groups were not significant. The histopathological findings of control group was normal. In vpa group, it showed extensive degenerative changes especially in myelin coat. In addition, most prominent finding in this group was condensation of collagen fibers in extensively demyelinated samples, while moderately effected areas were relatively normal. Both vpa+fa and vpa+ vit e groups exhibited similar ultrastructural changes, reflecting minimal to moderate degenerative changes. In vpa+fa+vit e group had almost the normal structure. Administration of single doses of valproic acid (400 mg/kg) resulted in a deteriorative effect on sciatic nerve at ultrastructural level. Administration of FA and Vit E had a protective effect to prevent the degenerative changes to a certain degree. Combination of FA and Vit E together following VPA administration had a more potent protective effect. The objective of the present study is to analyze histopathologic changes which may occur in a high risk experimental model after the administration of valproic acid. In addition, protective roles of the administration of folic acid and vitamin E are assessed.
