Adenosine Deaminase in the Diagnosis of White Muscle Diseases in Lambs
(Polish Soc veterinary Sciences Editorial office, 2006) Altug, N.; Agaoglu, Z. T.; Yuksek, N.; Kaya, A.; Keles, I.
The aim of the study was to investigate the importance of ADA serum and its isoenzyme activity in diagnosing white muscle disease in lambs. The animal material used in the study was forty seven Akkaraman lambs - twenty seven of which had clinical signs of white muscle disease (white muscle disease group) and twenty healthy lambs (control group). Blood samples were taken and Se levels, CK, LDH, AST, ADA and ADA izoenzyme activity were determined. Following this, the animals in the white muscle disease group received I mg sodium selenit + 60 mg vitamin E intramuscularly as a single dose. Fourteen days following sodyum selenit + vitamin E application blood samples were again taken and the same analysis repeated. Apart from ADA2 activity, other enzyme activities were significantly high (p < 0.001), and serum Se concentrations were significantly low (p < 0.001) in animals of the white muscle disease group compared to the control group. When the parameters obtained from the white muscle disease group were compared before and after treatment it was indicated that all enzyme parameters decreased significantly (p < 0.001) after treatment. On the other hand, serum Se concentration increased (p < 0.01) after treatment in the diseased group. The results confirm that determining ADA serum and its isoenzymes, together with CK, LDH and AST values seems to be useful in diagnosing white muscle disease.
Assessment of Electrocardiographic Findings, Serum Nitric Oxide, Cardiac Troponins and Some Enzymes in Calves With Hyperkaliemia Related To Neonatal Diarrhoea
(Ecole Nationale veterinaire Toulouse, 2011) Ozkan, C.; Altug, N.; Yuksek, N.; Kaya, A.; Akgul, Y.
The aims of the present study were to characterize ECG changes in calves with hyperkaliemia due to neonatal diarrhoea and to determine concomitant variations of serum concentrations of NO and of sonic cardiac markers such as cardiac troponins I and T and serum enzyme AST, LDH, CK and CK-MB activities. For that, ECG examinations were performed and serum biochemical parameters were measured in 13 diarrhoeic calves developing hyperkaliemia before and 5 hours after intravenous electrolyte (NaCl and Na2HCO3) administration and also in 5 healthy control calves. Compared to controls, diarrhoeic and hyperkaliemic calves exhibited significant alterations in electrolyte concentrations (Increases of K, Mg and P concentrations coupled to decreases of Na and Cl concentrations), a significant blood accumulation of nitrogen compounds (BUN and creatinine) and significant increases in ALP, LDH, CK and GGT activities. Furthermore, the serum NO concentrations have greatly enhanced in some individuals. By contrast, the serum troponin concentrations and the heart specific CK-MB and AST activities were similar between the 2 groups whereas electrocardiography changes were evidenced in diarrhoeic calves: P wave anomalies were observed in sonic diseased calves and the mean amplitude and the mean duration of the QRS complex and the T wave were markedly increased. The fluid electrolyte therapy has restored the electrolyte balance and has globally improved the parameters of the cardiac function but has failed to counteract the blood azote accumulation and the release of ALP, LDH, CK and GOT enzymes and even has aggravated the decreases in total protein and albumin concentrations and the glycaemia variations. These results suggest that the diarrhoea-related hyperkaliemia has led to disturbances into the cardiac function without inducing severe myocardium lesions in calves but was coupled to acute renal failure.
Effect of Carboxymethylcellulose, Icodextrin and Hyaluronic Acid Solutions on Postoperative Intraabdominal Adhesion Formation in Rabbits and the Role of Cytokines in Intraabdominal Adhesion Formation
(Polskie Towarzystwo Nauk Weterynaryjnych, 2024) Karasu, A.; Altug, N.; Bakir, B.; Yener, Z.
In this study, the aim was to investigate the effects of 1% CMC, 4% ICO and 0.4% HA solutions in preventing postoperative IAs and their contribution to peritoneal wound healing, as well as the relationship of cytokines with the formation of postoperative IAs in rabbits. The material of the study consisted of 32 healthy rabbits. Rabbits underwent median laparotomy following general anesthesia. Serosal abraded was created at the antimesenteric border of the cecum. Next, a 3 × 2 cm peritoneum was excised on the right abdominal wall and the defect was closed using with a 2/0 silk suture. The rabbits were randomly assigned to either of the following four treatment groups: CNT (0.9% NaCl), ICO (4% icodextrin), HA (0.4% hyaluronic acid) and CMC (1% carboxymethyl cellulose). Both cecum and peritoneal surfaces were treated with 20 ml each of treatment solutions. On the 7th postoperative day, the rabbits were euthanized with a lethal dose of sodium pentobarbital and the degree of adhesion was evaluated. Samples taken from the peritoneal defect were examined histopathologically and tissue hydroxyproline levels were measured. Serum TNF-α, IL-1 and IL-6 levels were measured from blood samples taken before the surgery and at 1, 6, 24 and 48 hours after the surgery. It was observed that the adhesion grade in the HA group (p < 0.05) and CMC group (p < 0.01) was significantly lower than the control group. Although peritoneal tissue hydroxyproline levels were lower in the other groups compared to the control group, they were not statistically significant (p > 0.05). In rabbits with adhesion formation, it was determined that TNF-α levels increased at the 6th postoperative hour (p < 0.05), and IL-6 levels increased at the 6th, 24th and 48th postoperative hours (p < 0.001) compared to preoperative. In this study, treating tissues with 0.4% HA and 1% CMC solutions suppressed peritoneal inflammation, and this resulted in an increase in the levels of proinflammatory cytokines TNF-α and IL-6. It has been determined that the application of these solutions reduces postoperative adhesion formation. It was concluded that TNF-α and especially IL-6, which are proinflammatory cytokines, can be a non-invasive biomarker in determining postoperative IA formation and evaluating the adhesive process. © 2024 Polskie Towarzystwo Nauk Weterynaryjnych.

The Effect of Oxfendazole Plus Oxyclozanide Paste and Tablet Formulations on Parasite Burden and Metabolic Status of Sheep
(Medwell online, 2008) Gunes, V.; Inci, A.; Uyanik, F.; Yildirim, A.; Altug, N.; Eren, M.; Gelfert, C. C.
The aim of the present study was to evaluate the effects of anthelmintic treatment with Oxyclozanid + Oxfendazole in different formulation (paste and tablet) on parasite load and metabolic status in sheep. Forty five sheep, infected with various gastrointestinal parasites and kept on a grazing flock, were evenly divided into 3 groups. Sheep in the control group did not receive any treatment. The sheep in the remaining groups received the same dose of Oxyclozanid (5 mg kg(-1) body weight) and Oxfendazole (13.5 mg kg(-1) body weight) in combination either as tablet or as paste. Faeces and blood samples were collected pre-treatment (day 0) and on day 14 post-treatment. Several gastrointestinal nematode parasites were detected in the faecal samples. Eggs PerGram (EPG) on days 0 and 14 were 100 +/- 18 and 78 +/- 8 in CG, 96 +/- 12 and 6 +/- 3 in TG and 76 +/- 9 and 2 +/- 2 in the PG, respectively. Serum total protein and globulin concentrations increased significantly (p<0.05) in CG and PG on day 14 compare to pre-treatment levels. In both sampling times total protein levels did not differ whereas a slight decrease in paste group and a significant decrease in tablet group were detected concerning globulin level, but no significant difference was detected between the tablet group and paste group on day 14 post-treatment. In paste group serum albumin level increased (p<0.05) on day 14 compare to baseline level. Compare to control group, albumin level slightly increased in tablet group, whereas it significantly increased in paste group on day 14 post-treatment. On day 14 in paste group Pi, Mg and Cu levels were higher (p<0.05) than the post-treatment levels of the remaining groups. A combination of Oxyclozanid+Oxfendazole is effective to eliminate parasite burden in sheep. Drug formulation does not have any influence on the metabolic status of the sheep.
Effects of Onion Juice Administration on Electrocardiogram in Dogs
(2009) Ceylan, E.; Aytekin, I.; Keles, I.; Altug, N.
The purpose of this study, was to investigate the effects of Onion Juice Administration (OJA) on Electrocardiogram (ECG) in dogs. Five clinically healthy street dogs were used in this study. Onion juice was given through oro-gastric tube of 400 g onion kg-1 body weight dose in 500 mL water. Blood samples were collected at just before and after (6, 12 and 24th h) Onion Juice Application (OJA). PCV, heart beats counts and electrocardiograms of the animals in the same time were determined. PCV values gradually, decreased and these decreases were significant at 6th (p<0.01), 12th (p<0.01) and 24th (p<0.001) h after OJA. Bradicardia was observed at 6th (p<0.05) and 12th (p<0.001) h after OJA whereas tachycardia was observed at 24th h (p<0.001). Before and 6th h after OJA heart rates were within normal limits in this study. First degree heart block occurred 12th h after OJA and aritmia was obvious at this time. P-Q interval also increased. Bradicardia developed in some derivations. The mean heart rate was approximately 60 beats min-1. Twenty-four hours after OJA tachycardia developed and the mean heart rate was 130 beats mm-1. In summary, OJA caused the anemia (reduction in the PCV values,) 1st degree heart block, tachycardia in dogs. Further studies on this issue, might be helpful for determining the effects of OJA on ECG in different species. © Medwell Journals, 2009.
Enhancement of the Glucose Metabolism and the Reverse Cholesterol Transport by a Peroxisome Proliferator Receptor Α (Pparα) Agonist Included in the Fasciolosis Treatment in Naturally Infested Sheep
(Ecole Nationale veterinaire Toulouse, 2013) Yuksek, N.; Altug, N.; Denizhan, V.; Ceylan, E.; Agaoglu, Z.
The purpose of this study was to investigate the effects of PPAR alpha agonist on metabolic parameters in naturally Fasciola-infected sheep. Twenty sheep with fasciolosis were allotted in 2 equal groups according to the received treatment (triclabendazole/levamisole in the group I and triclabendazole/levamisole + PPAR alpha agonist (2-methyl-2-phenoxy-propionic acid) in the group II) and the haematological and biochemical parameters were assessed before the treatment and 7, 14 and 28 days after and were compared to control values determined from 10 healthy sheep. As expected, fasciolosis has induced an anaemia evidenced by low haematocrit and low haemoglobinemia coupled to eosinophilia and to a moderate lymphopenia, severe liver damage characterised by hepatocyte degenerescence (significant increases in serum AST and GDH activities) and bile duct obstruction (significant increases in serum GGT activity and in serum bile acid concentrations) leading to impairement in liver metabolic functions (hypoalbuminemia, marked decreases in serum glucose concentrations and in LDL associated cholesterol concentrations). All the heamatological and biochemical alterations were at least partially alleviated by the antihelminthic treatment except the serum triglyceride concentrations which have continued to decrease during the post-treatment period and the total cholesterol and HDL associated cholesterol concentrations which have markedly increased, particularly when sheep were also treated with the PPAR alpha agonist. These results clearly demonstrated the severe metabolic liver impairment occurring during fasciolosis in sheep and the beneficial effects of the PPAR alpha agonist on the correction of the negative energy balance, particularly by promoting the reverse cholesterol transport.
Evaluation of the Anesthetic Effects of Xylazine-Ketamine, Xylazine-Tiletamine and Tiletamine-Zolazepam Using Clinical and Laboratory Parameters in Rabbits
(Polskie Towarzystwo Nauk Weterynaryjnych, 2018) Karasu, A.; Altug, N.; Aslan, L.; Bakir, B.; Yuksek, N.
The aim of this study was to evaluate the anesthetic effects of xylazine-ketamine (XK), xylazine-tiletamine-zolazepam (XTZ) and tiletamine-zolazepam (TZ) using hematological and biochemical parameters in rabbits. ' A total of 18 rabbits were divided into three equal treatment groups (n = 6). The rabbits in the XK, XTZ, and TZ groups were administered xylazine (5 mg/kg) and ketamine (50 mg/kg), xylazine (5 mg/kg) and TZ ; (15 mg/kg), and TZ (15 mg/kg), respectively, via the intramuscular route. Following the injection, their reflexes ; were tested every 5 minutes. Heart rate, respiratory rate, and body temperature were determined before ; the injection (0 min) and at 5, 15, 30, 45, 60, 75, 90, and 120 min after injecting the anesthetic combinations. Furthermore, hematological and biochemical (alanine transaminase [ALT], aspartate transaminase [AST], alkaline phosphatase [ALP], bilirubin, blood urea nitrogen [BUN], and urea) analyses were also performed before, during, and after anesthesia administration. The duration of anesthesia and loss of reflexes were significantly longer in the XTZ group than in the other groups. However, in the TZ group, reflexes were remained. Respiratory rate and body temperature decreased in all the groups. Moreover, heart rate reduced only in the XK and XTZ groups, and the hematological parameters of all groups were comparable. Serum AST and ALP levels increased in the XTZ group compared to that in the XK and TZ groups, respectively. However, these increases were within the reference limits. The post-anesthesia serum BUN and urea levels significantly increased in the XTZ group (p < 0.05) compared to that in the other groups. Thus, although the XTZ combination provided satisfactory anesthetic effect in rabbits, it may be nephrotoxic. Therefore, its use for anesthesia induction in invasive renal procedures and experimental nephrotoxicity studies is not advisable. © 2018 Polskie Towarzystwo Nauk Weterynaryjnych.

A Pcr Method With Internal Control for Detection of Brucella Spp. From Bovine Abortion Samples
(Ecole Nationale veterinaire Toulouse, 2014) Solmaz, H.; Cantekin, Z.; Altug, N.; Ilhan, Z.; Aslan, S.; Ergun, Y.
Brucella spp. are important infectious agents in bovine abortions worldwide. The bacteriological culture of Brucella spp. is fastidious and time consuming procedure as a classical laboratory method. Brucella spp. can be detected by using different molecular techniques. The aim of this study is to develop a PCR technique with an internal control for detection of Brucella spp. from bovine abortion samples. For this purpose, the sensitivities of three different primer pairs (BgF/BgR, B4/B5 and JP-R/JP-F) were compared. Bovine 12S gene specific primer pairs (12SM-FW/12SBT-REV2) were used as an internal control. The sensitivity of BgF/BgR primers was found higher than the other primer sets. A PCR assay was developed by combining BgF/BgR primer sets and primers for bovine 12S. This protocol was tested and validated by using abomasal contents of two Brucella-positive and eighteen Brucella-negative clinical samples. In conclusion, the developed PCR method with an internal positive control has a potential for use in direct detection and identification of the Brucella spp. from bovine abortion samples.
Serum Biochemical Profile and Protein Fractions in Cattle With Theileriosis
(Ecole Nationale veterinaire Toulouse, 2014) Dede, S.; Altug, N.; Deger, Y.; Ozdal, N.; Ceylan, E.
Theileriosis encountered frequently in Van region and causes huge economic losses in cattle, sheep and goats. This study was carried out to examine the serum biochemical profile and serum protein fractions, determined before and 7 days after buparvaquone treatment, in 28 cattle, diagnosed to be infected with T. annulata and in 15 healthy control animals from the same region. The ALT (alanine amino transferase) and ALP (alkaline phosphatase) activities and the concentrations of bilirubin and urea were markedly increased in sera from infected animals whereas the concentrations of glucose, minerals (Na, K and Ca), total proteins, albumin and of a-globulins and the albumin/globulin (A/G) ratios were significantly depressed compared to the controls. In addition, buparvaquone treatment succeeded in alleviating the serum biochemical anomalies. These results show that liver and kidney failures occur during theileriosis leading to a global protein deficiency and that serum biochemistry and serum protein analysis may allow biochemical evaluation of treatment.
Serum Potassium-Lowering Effects of Insulin Plus Dextrose and Adrenalin Treatment That Enhance Intracellular Potassium Transitions in Hyperkalemic Diarrheic Calves
(Univ Agriculture, Fac veterinary Science, 2016) Altug, N.; Yuksek, N.; Ozkan, C.; Basbugan, Y.; Keles, I.; Agaoglu, Z. T.; Akgul, Y.
The study examined the serum potassium-lowering effects of different treatment options for hyperkalemia in diarrheic calves (n=18). Calves were allocated into three treatment groups. All groups received isotonic sodium bicarbonate solution for a period of 90 minutes. The animals in group 1 received no further treatment, those in group 2 received a further dose of 50% dextrose and insulin, and those in group 3 received a further dose of adrenaline. High serum K levels in all groups significantly decreased after treatment (AT) than before treatment (BT). Serum potassium levels AT in groups 2 and 3 were found to be significantly lower than those in group 1. Increase in pH, bicarbonate and total carbon dioxide values were observed AT in all groups. However, bicarbonate and total carbon dioxide levels in the AT were not statistically significantly different from those in the adrenaline group compared with the groups 1. These parameters were significantly lower in the group 2. Moreover, the concentration of glucose in the groups 2 in contrast to the adrenalin group was higher than that in both the BT and group 1 AT. The insulin + dextrose combination and adrenaline applications in hyperkalemic calves had similar effects. However, the administration of adrenaline had a lower negative effect on metabolic acidosis treatment. (C) 2015 PVJ. All rights reserved
