Ilgaz Akata,Bulent Ergonul,Fatih Kalyoncu
International Journal of Pharmacology , 2012,
Abstract: In this study, chemical compositions and antioxidant activities of 16 wild edible mushrooms (Agrocybe cylindracea, Amanita ceciliae, Armillaria mellea, Boletus reticulatus, Cantharellus cibarius, Chlorophyllum rhacodes, Coprinus comatus, Flammulina velutipes var. velutipes, Lactarius deliciosus, Lactarius salmonicolor, Pleurotus ostreatus, Polyporus squamosus, Rhizopogon roseolus, Russula anthracina, Suillus collinitus and Tricholoma myomyces) were investigated. Antioxidant properties of methanol extracts were studied by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging method. Among the mushroom extract Amanita ceciliae and Pleurotus ostreatus (96.16 %) showed the most potent radical scavenging activities at 4.51 and 2.72 mg mL-1, respectively. The lowest scavenging activity was exhibited by C. rhacodes (70.46%) at 2.35 mg mL-1.

Pelin Gunc Ergonul,Bulent Ergonul,Fatih Kalyoncu,Ilgaz Akata
International Journal of Pharmacology , 2012,
Abstract: The fatty acids of five wild edible mushroom species (Agrocybe cylindracea, Coprinus comatus, Lactarius deliciosus, Suillus collinitus and Tricholoma myomyces) collected from different regions from Anatolia were determined. The fatty acids were identified and quantified by gas chromatography and studied using fruit bodies. Fatty acid composition varied among species. The dominant fatty acid in fruit bodies of all mushrooms was cis-linoleic acid (18: 2). Percentage of cis-linoleic acid in species varied from 36.29-66.72%. The other major fatty acids were, cis-oleic, palmitic and stearic acids, respectively. Fatty acids analysis of the mushrooms showed that the unsaturated fatty acids were at higher concentrations than saturated fatty acids.

Journal of Diabetes Mellitus (JDM) , 2017, DOI: 10.4236/jdm.2017.74018
Abstract: Background: The evidence indicates that vitamin D [25(OH)D] improves glycaemic outcomes in type 2 Diabetes mellitus patients. The outcome measures used to determine the accuracy of this hypothesis are: glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG) and homeostasis model assessment-insulin resistance (HOMA-IR). Methods: We performed a systematic review and meta-analysis which included all previous randomised controlled trial (RCT) studies that assessed the effects of vitamin D on glucose metabolism. We carried out an extensive electronic database search of published and unpublished RCTs, evaluating the association between vitamin D and glycaemic outcomes in type 2 diabetes mellitus patients. We searched Cochrane Library, PubMed, EMBASE, CINAHL Plus with Full Text, MEDLINE, BioMed Central, Turning Research Into Practice (TRIP), Health Technology Assessment (HTA), and Latin American and Caribbean Health Sciences (LILIACS) between the years 2005 and 2016. The full texts of relevant studies were retrieved and a snowballing technique was used to discover further studies missed from the initial database search. This was done by hand-searching for references within the retrieved articles. Results: A total of 17 studies were included in the review. The pooled effect of 15 studies that measured HbA1c showed an insignificant effect of vitamin D on HbA1c (Mean difference (MD) = -0.06 mmol/l; 95% CI = -0.26 to 0.14; I2 = 76%). A pooled analysis of seven studies that measured the effect of vitamin D on blood glucose also found no significant effect of vitamin D on T2DM (MD = -0.03 mmol/l; 95% CI = -0.69 to 0.63; I2
A Case of Pituitary Hemorrhage Following Cardiopulmonary Bypass Surgery  [PDF]
Ozgen Ilgaz Kocyigit, Serdar Kabatas, Erdinc Civelek, Ezgi Tuncay, Oguz Omay, Tufan Cansever, Ayda Turkoz
Surgical Science (SS) , 2011, DOI: 10.4236/ss.2011.23034
Abstract: A 68-year-old female patient with previous history of transsphenoidal hypophysectomy operation underwent three-vessel coronary artery bypass graft (CABG) surgery for extensive coronary artery disease. Preoperative neurological examination revealed sequelae visual loss at right temporal visual field. Follow-up Magnetic Resonance Imaging studies showed a residual hypophyseal tumor tissue extending to suprasellar area. No additional pathology was detected in the early postoperative cranial control CT, but aggravation of visual field defect was determined. Coincidently, cranial magnetic resonance imaging (MRI) showed hemorrhage into the tumor tissue. We decided to follow-up the patient who exhibited no additional symptoms and was discharged well on the fifth day due to the signs of resolution of hemorrhage. Follow-up controls of the patient at sixth and twelfth months demonstrated normal hormone levels without any additional clinical complaints. We present preoperative assessment, perioperative anesthesia management, and postoperative clinical follow-up of a patient with a residual hypophyseal tumor.
ESTIMATION OF THE NUMBER OF NEURONS IN THE HIPPOCAMPUS OF RATS WITH PENICILLIN INDUCED EPILEPSY
Ilgaz Akdogan,Nedim Unal,Esat Adiguzel
Image Analysis and Stereology , 2002, DOI: 10.5566/ias.v21.p117-120
Abstract: Epilepsy is a neurological disease arising from strong and uncontrollable electrical firings of a group of neurons in the central nervous system. Experimental epileptic models have been developed to assess the physiopathology of epileptic seizures. This study was undertaken to estimate the number of neurons in the rat hippocampus with penicillin induced epilepsy, using a stereological method, "the optical fractionator". In the experimental group, 500 IU penicillin-G was injected intra-cortically, and in the control group, the same volume of saline was administered. A week later, the animals were decapitated and their brains were removed by craniatomy. Frozen brains were cut with a thickness of 150 ěm in a cryostat. Sections were collected by systematic random sampling and stained with hematoxylen-eosin. Microscopic images of pyramidal cell layers from hippocampus CA1, CA2 and CA3 subfields were then transferred to a monitor, using a 100x objective (N.A. = 1.25). Using the optical disector method, the neurons were counted in the frames and determined with a fractionator sampling scheme. The total pyramidal neuron number was then estimated using the optical fractionator method. The total pyramidal neuron number was found to be statistically lower in the experimental group (mean = 142,888 ± 11,745) than in the control group (mean = 177,953 ± 10,907) (p < 0.05). The results suggest that a decrease in the hippocampal neuronal number in a penicillin model of epilepsy can be determined objectively and efficiently using the optical fractionator method.

?zlem SOLAK,ümit DüNDAR,Kadir ILGAZ
Duzce Universitesi Tip Fakültesi Dergisi , 2010,
Abstract: Neurofibromatosis Type 1 (NF1) is a multisystemic disease, manifesting as abnormalities ofthe nervous tissue, bones, soft tissue, and skin. The entity is dominantly inherited and affects 1in 4000 individuals. Cafe-au-lait spots, peripheral neurofibromas, Lisch nodules and axillaryfreckling are the characteristics of NF1. Bone abnormalities are usually observed in NF1. Scoliosis is a skeletal anomaly reported to beassociated with NF1. We made a diagnosis of NF1 and scoliosis secondary to NF1 in our 26-year-old male case with complaints of low back pain, a mass on his left hip beginning 10 yearsago and growing and with cafe-au-lait spots on his back. We think that, in daily practice, it isimportant to look for cafe-au-lait spots with inspection in the patients coming with the complaintof low back pain and when these spots are observed a diagnosis of NF1 should be suspected.Besides, we wanted to emphasize that scoliosis should be searched in the patients with adiagnosis of NF1 and low back pain.
A Case of Hemicrania Continua Presenting As Temporomandibular Pain and Responding To Topiramate
Elif Ilgaz AYDINLAR,Dilaver KAYA,Fehim ARMAN
Journal of Neurological Sciences , 2012,
Abstract: Hemicrania continua (HC) is a primary headache disorder, characterized by unilateral, unremitting headache of moderate to severe intensity, associated with ipsilateral autonomic signs and an absolute response to indomethacin. We report a case of a 34–year-old woman who presented with strictly left-sided unremitting headache whose initial symptoms suggested a temporomandibular disorder, but the patient was ultimately diagnosed with hemicrania continua. The patient displayed an absolute response to a trial of indomethacin but she had to quit soon due to gastric intolerance and vertigo. Then topiramate was prescribed which she responded completely. This case and the other reports as well suggests that the differential diagnosis of temporomandibular disorders and HC is challenging. HC generally needs to be treated lifelong and indomethacin may not be a good choice because of its side effect profiles while topiramate may be considered as an alternative. The IHS criteria of HC need to be revised to provide a broad based description thus providing new therapeutic options.
