The Effect of Ration Supplemented With Zinc on Ecg in Broilers
(Scientific Technical Research Council Turkey, 2001) Çinar, A; Dönmez, N
This study was carried out to evaluate the effects of ration supplemented with zinc on the electrocardiograms of 60 broiler chicks. The chicks were divided into four groups, one control and three experimental groups (II, III, IV). Zinc was given to the experimental groups at doses of 125, 500, 1000 mk/kg respectively, in their ration for 60 days. The electrocardiogram recordings were performed on chicks on the 60(th) day of the experiment. Leads I, II, III, aVR, aVL and aVF were recorded in the electrocardiographs of the chicks. All electrocardiograms exhibited P, R, S and T waves but P wave generally interfered with the T wave. No Q waves were observed. AII the waves in lead I were very low or almost isoelectric. The R and S waves in leads II and III were of about equal amplitude. The T waves in leads I, II, III and aVF were positive but in leads aVR and aVF they were negative. The heart rates of the groups were found to be 363, 362, 400 and 410 per minute respectively, but the differences among the groups were not statistically significant, in the groups, the mean electrical axis of heart was found to be between -60 degrees and -110 degrees, with their averages of -80 degrees, -85 degrees, -92 degrees and -88 degrees respectively.
The Effects of Carbon Tetrachloride (Ccl4) Induced Experimental Acute and Chronic Intoxication on Histological Structure of Liver and Some Hematological Values and Electrocardiogram in Rabbits
(Scientific Technical Research Council Turkey, 1999) Çinar, A; Yörük, M; Meral, I; Kiliçalp, D; Koç, A; Ertekin, A
This paper reports an investigation of the effects of acute and chronic carbon tetrachloride intoxications on the histologic structure of the liver and hematological values and electrocardiograms in rabbits. The rabbits were divided into 3 groups of 7. The first group was the control group, the second group was acutely intoxicated and the third group was chronically intoxicated. In the acutely intoxicated group, caryorexsis, along with necrosis was observed in the hepatocyte of the centrolobular area of the liver. In the chronically intoxicated group, connective tissue mass around the V. centralis increased. This increase of connective tissue caused chirrosis. Hematological values of the groups were as follows: red blood cells 5.86+/-0.6, 5.95+/-1.5, 4.26+/-0.7 billion/mm(3); white blood cell: 6.9+/-1.35, 5.90+/-0.8, 4.0+/-2.44 thousand/mm(3); hemoglobin concentration: 12.7+/-0.9, 13.6+/-1.5, 11.8+/-1.2 gr/dl; hematocrit value: 41.8+/-3.3, 44.6+/-4.9, 33.0+/-4.4%; sedimentation: 5.2+/-1.6, 8.0+/-2.8, 10.2+/-1.3 45 degrees/1 hours respectively. The formula leukocyte was as follows: in the control group: neutrophil 34+/-5.3%, eosinophil 0.6+/-0.8%, basophil 0.2+/-0.4%, lymphocyte 62+/-5.02%, monocyte 3.2+/-0.97%. In the acutely intoxicated group: neutrophil 7.75+/-1.1%; eosinophil 1+/-0%; basophil 0+/-0%; lymphocyte 88.5+/-1.3%; monocyte 3.5+/-1.8%. In the chronically intoxicated group: neutrophil 60+/-8.51%; eosinophil 1+/-0.71%; basophil 0+0%: lymphocyte 35.75+/-7.33%; monocyte 3.2+/-0.83%. The extremity leads and 2 vertical and 1 horizontal chest leads were used in the electrocardiograph of the rabbits, All waves were observed in all derivations. The P and T waves were negative in the III and aR leads and positive in the other leads, The amplitudes of waves decreased (hypo voltage) as a result of intoxication. In the groups, the heart rates were 219+/-21 in the control. 215+/-17 in the acutaly intoxicated, 201+/-35 per minute in the chronically intoxicated and the mean electrical axes of the heart rate were 45 degrees+/-20, 50 degrees+/-27. 35 degrees+/-20 respectively. Statistical comparisons were carried out using analysis of variance and Q test.
Effects of Chronic Fluorosis on Electrocardiogram in Sheep
(Humana Press inc, 2003) Dönmez, N; Çinar, A
This study was carried out to evaluate the effects of chronic fluorosis by means of the electrocardiograms in sheep. Ten sheep with fluorosis living around a volcanic mountain (Tendurek Mount) in East Anatolia in Turkey and 10 healthy sheep were used. Leads I, II, III, aVR, aVL, aVF, V-2, V-4, and V-10 were recorded in the electrocardiographs of the sheep. All waves were seen in all derivations. The P-Q interval was significantly (p < 0.05) prolonged and sinus bradycardia was observed in the sheep with fluorosis. As a result of this, the number of heart beats was decreased significantly (p < 0.05); that is, the number of heart beats was 110 +/- 15 in the control group and 75 +/- 10 in sheep with fluorosis.
Effects of Different Concentrations of Monensin on the Electrocardiogram and the Serum Ion Balance of the Rabbit
(Scientific Technical Research Council Turkey, 1998) Meral, I; Çinar, A; Bayiroglu, F; Aslan, SO
The present study was planned to investigate the effects of two different concentrations (10 and 40 mg/kg) of monensin, carboxylic ionophore antibiotic, on the ECG and the serum Na+ and K+ concentrations of rabbits. Fifteen male rabbits, about 2 kg and 1 year old, were used. ECGs were recorded by a direct writing electrocardiograph. Blood samples for measuring serum Na+ and the K+ concentrations were collected and the leads I, ii, II, aVR, aVL and aVF were recorded before and 6 hours after monensin was given. The durations and amplitudes of waves on the trace were measured in lead II and electrical axis also measured in leads 1 and III. We found that the effects of monensin on ECG and the serum Na+ and the K+ concentrations were dose dependent. In low doses (10 mg/kg) it produced a sinusoidal tachycardia by decreasing the time interval between two impulse production by sinoatrial node without changing the serum ion balance. However, in high doses (40 mg/kg) it produced a sinusoidal tachycardia with increasing the serum K+ and decreasing the serum Na+ concentrations.
The Effects of Different Silage Additives on Rumen Protozoan Number and Volatile Fatty Acid Concentration in Sheep Fed Corn Silage
(Elsevier Science Bv, 2003) Dönmez, N; Karsli, MA; Çinar, A; Aksu, T; Baytok, E
The main objective of this study was to determine the effects of different silage additives on protozoan population, genera and total volatile fatty acid (VFA) concentrations and percentage of VFAs in corn silage. Four ruminally fistulated Morkaraman x Kivircik lambs were used in a 4 x 4 Latin square design with 14-day adaptation and 1-day sampling periods. The animals were offered 20% cottonseed meal and 80% corn silage with or without treatment with silage additives, ad libitum intake. Silages used in the experiment were corn silage without treatment, treated with 5% molasses, 0.05% formic acid, and 10 g/t enzyme. Total protozoan number was significantly different among treatments (P < 0.05). It was the highest in sheep fed silage treated with molasses (313.2 x 10(3) ml(-1)) and the lowest in sheep fed silage treated with formic acid (168.0 x 10(3) ml(-1)). Entodinium, Epidinium, Isotricha, Dasytricha, Diplodinium, and Osphyroxscolex types were observed in all treatments, but major protozoan genera were Entodinium, comprising 61-69% of total protozoan population. Total VFA concentration was significantly less in sheep fed enzyme-treated silage compared with other treatments. Percentage of acetic acidwas significantly lower (P < 0.05) in sheep fed silage treated with molasses compared with other treatments, but percentages of propionic acid, and butyric acid were similar among treatments. Ruminal ammonia-N concentrations ranged from 7.71 to 15.87 mg/dl and were lowest in sheep fed enzyme-treated silage among treatments (P < 0.05). In conclusion, the highest protozoan counts were observed in the rumen of sheep fed corn silage treated with molasses. (C) 2003 Elsevier Science B.V. All rights reserved.
Effects of Stress Produced by Adrenocorticotropin (Acth) on Lipid Peroxidation and Some Antioxidants in Vitamin C Treated and Nontreated Chickens
(South African Journal of Animal Sciences, 2003) Belge, F; Çinar, A; Selçuk, M
The aim of this study was to examine the effects of vitamin C on malonaldehyde (MDA) and glutathione (GSH) concentrations, and superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activity in chickens stressed by adrenocorticotropin (ACTH). Sixty Leghorn chickens (20 weeks old) were randomly allotted to a control and a vitamin C treated group. An isotonic sodium chloride solution was administrated intramuscularly for a period of five days to the control group at a dose of 2.5 mL per chicken per day, and the treatment group received a vitamin C solution (containing 250 mg vitamin C/2.5 mL) intramuscularly for five days. On the fifth day of the experiment the chickens in both groups received 50 IU ACTH intramuscularly. Three hours after ACTH application blood samples were collected to determine the concentrations of MDA and GSH, and activities of SOD and GSH-Px in the blood. The concentration of MDA in the control group increased compared to that in the vitamin C treated group. After the ACTH application the activity of SOD increased in both groups, thought significantly so in the vitamin C treated group. The GSH-Px activity did not differ significantly between the treatments after ACTH application. It was concluded that intramuscularly administrated vitamin C facilitated an adaptation against stress and decreased negative effects of stress in chickens.
Investigation of the Effects of Age, Sex and Season on Electrocardiographs (Ecg Values) and Heart Radiographs of Healthy Van Cats
(Scientific Technical Research Council Turkey, 2003) Kiliçalp, D; Çinar, A
This study was carried out to investigate the effects of age, sex and season change on electrocardiograms of Van cats. Thirty-eight (male and female) healthy Van cats, 3-15 months old were used. Electrocardiograms (ECGs) and heart radiographs were obtained from cats seperately in summer, autumn, winter and spring. ECGs were recorded as bipolar, augmented unipolar and precordial leads (CV6LL, CV6LU, V-10). Durations and amplitudes of waves on the trace were measured in lead II and the electrical axis also measured in leads I and III. Radiographic examination was performed in the right lateral recumbency position (covering the whole thoracic cavity) and the dose of the X-ray beam was 44-47 kV. The duration of P wave was 0.04 s. and its amplitude was 0.10 mV-0.12 mV. The PR interval was 0.06-0.08 s. The duration of the QRS complex was 0.03-0.04 s and its amplitude was 0.16 mV-0.5 mV. The duration of the T wave was 0.06-0.09 s. and its amplitude was 0.1 mV-0.15 mV. The duration of the QT interval was 0.15-0.18 s. The T wave was negative in all of the aVR leads and in some of leads 11, aVL and V4. The mean electrical axis of the cats was +66.5degrees to +87.5degrees. No significant differences were seen among the groups. The heart rate in the first group was determined by seasons to be 200 +/- 12(a), 170 +/- 5.9(b), 193.2 +/- 12(a) and 207.2 +/- 15(a) beat/min (a,b: P < 0.05); in the second group 201 +/- 8.7, 179.8 +/- 5.1, 202.8 +/- 14 and 195.6 +/- 5.2 beat/min; in the third group 176.2 +/- 7.7, 170 +/- 7, 186.6 +/- 13 and 193.5 13 beat/min; and in the fourth group 186.3 +/- 16, 180 +/- 14, 200 +/- 11 and 210 +/- 15 beat/min, respectively. According to radiographic examinations. the heart was located 4(th) - 7(th) and 5(th) - 7(th) intercostal intervals.
