    Arrhythmia due to reperfusion after thrombolytic therapy in patients with acute myocardial infarction
    (2004) Tavlı, Talat; Avşar, Alaettin; Korkut, Bayram; Doğan, Abdullah; Demir, Sedat; Sarı, Refik Ali; Gök, Hasan
    Objective: The aim of this study was to determine the relation between the incidence and frequency of ventricular arrhytmias and the time course of ST-segment changes in patients with successful thrombolysis. Method: This study included 46 patients (31 males 53±12years) with acute myocardial infarction (MI) who were treated with streptokinase (SK Group) and 41 MI patients (27 males 55±12 years) who did not receive any thrombolytic agent (Control Group). Electrocardiograms were obtained 90 minutes 6, 12, 18, 24, 48 and 72 hours after thrombolytic therapy and reduction in ST elevation at 90 minutes was calculated. All patients had wall motion abnormalities. Results: Overall arrhythmias were observed in 67%(n: 31) of patients in SK group compared to 63% (n:26) in control group (p=0.05). In subgroup analysis of SK group ventricular tachycardia (VT) was more frequent (37%) in patients with more than 50% reduction in ST elevation at 90 minutes compared with in other subgroups of patients (p<0.01). Postinfarction angina and systolic dysfunction were more frequent in the control group compared to the SK group (p<0.05). Conclusion: Our results suggest that reperfusion with fibrinolytics or the faster ref low may induce ventricular arrhythmias. However, it can also prevent the impairment in systolic function of the left ventricle.

    In dieser Arbeit wurde die Embryotoxic-Einflüsse von Arsen in der ganseier untersucht In der Untersuchung wurde die Eier, die 100 gr. gewichte und mit Embryonen haben, verwendet. Die Eier wurden 4 Gruppe, die 20, 20, 15 und 15 Eier enthalt haben, klassifiziert. In der Eier der erstem Gruppe wurde das Arsen Untersucht. Zur Eier der zweiten Gruppe wurde am 2 Tag von Inkubation 0.9igem % 0.1 ml in jiziert. Zur Eier der diritten Gruppe wurde am 2 Tag von Inkübation 0.5 ppm Arsen injiziert und zur Eier der vi erten Gruppe wurde am 2 Tag von Inkübation 0.1 ppm Arsen injiziert. Die Injektion wurde zum Luftsäckchen gemacht. Die Eier wurde am 27 Tag von Inkübation genau untersucht, ob die Embryonen lebedig sein und die Malformation zeigen. In der Ergebnisse wurde beobachtet, dass die Embryonen in den 0.5 ppm Arsen injizierten Eiern 94% und in den 0.1 ppm Arsen injizierten Elern 60 % sterben. Ausserdem wurde in den beiden Gruppen die Missbildung betrachtet.

    The Effects of Nisoldipine on Carotid Artery Stiffness and Left Ventricular Functions
    (1995) Tavlı, Talat; Kozan, Ömer; Doğan, Abdullah; Cin, V. Gökhan; Gokçin, Ayşegül
    Doppler echocardiographic determinations, left ventricular (LV) fractional shortening (FS), cardiac output (CO), diastolic function parameter (E/A ratio) and carotid artery pulse wave velocity and stiffness were evaluated in 36 patients widi essential hypertension before and after nisoldipine treatment. Blood pressure decreased significantiy, and carotid artery width and fractional shortening increased significantly following nisoldipine administration (p < 0.0001). Carotid artery pulse wave peak velocity did not change following the treatment period (p > 0.05). In conclusion, short term nisoldipine administration improved blood pressure and LV systolic function, whereas LV diastolic function and carotid artery stiffness did not change. Nisoldipine did not alter serum biochemical parameters, including cholesterol, triglyceride, HDL-choles-terol, and LDL-cholesterol (p>0.05). Only one patient manifested symptoms of hypotension as an adverse effect of the drug. (Jpn Heart J 36: 629-637, 1995). © 1995, International Heart Journal Association. All rights reserved.

    Kars Bölgesi?nde Tüketime Sunulan Yemlerde Nitrat ve Nitrit Düzeyleri
    (Selçuk Üniversitesi, 1994) Liman, Bilal Cem; Doğan, Abdullah
    In this study, the contents of nitrate and nitrite in feeds marketed in Kars region were analysed The amount of nitrate and nitrite in feeds were measured colorimetrically as suggested by Sen and Donaldson. The analysed feeds were beef cattle feeds (30 samples), dairy cattle feeds (40 samples), grass, feed for cattle (40 samples), straw, feed for cattle (20 samples). The levels of nitrate and nitrite in beef cattle feeds ranged from 101.2 ppm to 7714.1 ppm and from 11.2 ppm to 19.8 ppm, in dairy cattle feeds ranged from 82.1 ppm to 947.2 ppm and from 1.1 ppm to 25.4 ppm, grass ranged from 38.4 ppm to 182.1 ppm and from 0.2 ppm to 1.1 ppm, straw ranged from 13.7 ppm to 63.8 ppm and from 0.7 ppm to 1.0 ppm, respectively. According to the data obtained from scientific li terature, it is concluded that the nitrate and nitrite levels determined in feeds will not give rise to acute or chronic toxicity in animals.
