Cardiac biomarkers in premature calves with respiratory distress syndrome

The aim of this study was to determine the clinical relevance of cardiac biomarkers [troponin I and T, creatine kinase-MB fraction (CK-MB) and lactate dehydrogenase (LDH)] in premature calves with respiratory distress syndrome. Seventy premature calves were admitted to the clinic within 24 h after birth. Respiratory distress syndrome was diagnosed in premature calves by clinical examination and venous blood gas analysis. Ten healthy calves, aged 5 days, were used as control. Cardiac troponin I and T were analysed using ELISA and ELFA, respectively. Serum CK-MB and LDH were also analysed in an automatic analyser. The calves had low venous pH, pO2, O2 saturation and high pCO2 values consistent with dyspnoea, hypoxaemia, and inadequate oxygen delivery. Mean serum troponin I, troponin T, CK-MB and LDH levels were increased in the premature calves compared to the control group. In conclusion, the results in this study demonstrated that serum CK-MB, troponin I and troponin T concentrations could be used for evaluating myocardial injury in premature calves with respiratory distress syndrome

Lipopolisakkarit ile endotoksemi oluşturulan buzağılarda akut faz cevap ve klinik değişimler

Amaç: Lipopolisakkarit ile deneysel endotoksemi oluşturulan buzağılarda akut faz proteinlerin ve klinik değişimlerin belirlenmesi amaçlanmıştır. Gereç ve Yöntem: Çalışmada yaşları 25-42 gün arasında değişen sekiz adet Holstein ırkı buzağı kullanıldı. Lipopolisakkarit damar içi 0.1 ?g/kg dozunda 50 mL % 0.9 NaCl’de seyreltilip 30 dakika süresince verilerek endotoksemi oluşturuldu. Çalışma boyunca endotoksemi gelişen buzağılarda klinik olarak gözlenen değişiklikler kayıt edilirken ve akut faz proeinlerinin konsantrasyonları belirlendi. Bulgular: Lipopolisakkarit uygulanması sonrasında buzağıların tamamında solunum sayısında ve kalp atım sayısında artış, yerde yatma, depresyon, hipotermi/hipertermi mukozada hiperemi/siyanoz ve emme refleksinde azalma gözlendi. Klinik olarak gelişen değişimler 1. ve 3. saatler arasında daha şiddetli olduğu belirlendi. Damar içi lipopolisakkarit verilmesinden sonra haptoglobin 36. saatte (500±93.2 ?g/ mL) ve serum amyloid-A 24. saatte (185± 46.6 ?g/mL) en üst seviyeye ulaştı. Öneri: Akut faz proteinlerde ve klinik bulgulardaki gözlenen değişim, buzağılarda gelişen endotoksemi ile ilişkilidir. Buzağılarda serum haptoglobin ve serum amyloid-A konsantrasyonlardaki artışlar endotokseminin bir belirteçi olarak değerlendirilebilir.Aim: The purpose of the study was to determine the levels of acute phase proteins and clinical changes in calves with lipopolysaccharide induced experimental endotoxemia. Materials and Methods: Eight Holstein breed calves were used in the study. Endotoxemia was induced via intravenous administration of 0.1 μg/kg dose of lipopolysaccharide in 50 mL of physiological 0.9% NaCl over 30 min. The calves were continuously observed for clinical changes during the experiment, and serum acute phase protein levels were measured. Results: Increase in respiratory frequency, tachycardi, mucosal hyperemia/cyanosis, recumbency, depression, hyperthermia/hypothermia, and poor suckle reflexes were observed in all calves after lipopolysaccharide administration. After lipopolysaccharide infusion, serum haptoglobin (500±93.2 μg/mL) and serum amyloid A (185±46.6) concentrations reached peak levels of at 36 h and 24 h, respectively. Conclusion: Changes in acute phase proteins and clinical findings were related to endotoxemia. A moderate to high increase in haptoglobin and serum amyloid A concentrations may indicate the presence of endotoxemia in calves

Utjecaj odnosa koncentracija bakra u hrani i plazmi na razvojnu ortopedsku bolest u ždrjebadi.

The study group consisted of ten foals, 3-6 months old, 6 male and 4 female, KWPN breed, with developmental orthopedic disease (DOD). The control group consisted of eight healthy foals. On clinical examination, lameness, swelling of joints, and pain were observed in all foals. Clinical, radiographic, and pathological findings in ten foals indicated DOD. Serum Cu concentrations in foals with DOD were significantly lower than in the control group (0.094 ± 0.011 mg/kg vs, 0.932 ± 0.068 mg/kg, respectively; P0.05), serum Ca levels (187.836 ± 7.921 μg/dL vs. 150.912 ± 5.271 μg/dL, respectively, P >0.05), and serum P levels (247.339 ± 10.729 μg/dL vs. 190.470 ± 5.775 μg/dL, respectively, P >0.05) were observed both in foals with DOD and in healthy foals. There were no statistically significant differences between the DOD group and the control group with respect to serum levels of Ca, P and Zn. We concluded that DOD is associated with reduced serum levels of Cu in foals. Copper is an important trace element for growing foals.Pokusna skupina sastojala se od 10 ždrjebadi s razvojnom ortopedskom bolešću, šest muške i četiri ženske, u dobi od tri do šest mjeseci, pasmine kraljevski nizozemski toplokrvnjak. Kontrolna skupina sastojala se od šest zdrave ždrjebadi. Sva je ždrjebad bila klinički pregledana na hromost, otekline zglobova i bol. Klinički, radiografski i patološki nalazi upućivali su na razvojnu ortopedsku bolest. Koncentracija bakra u ždrjebadi s razvojnom bolešću bila je značajno manja nego u ždrjebadi kontrolne skupine (0,094 ± 0,011 mg/kg u odnosu na 0,932 ± 0,068 mg/kg; P0,05, dok su serumske razine kalcija iznosile 187,836 ± 7,921 μg/dL u odnosu na 150,912 ± 5,271 μg/dL u kontrolne skupine, P>0,05, te razine fosfora 247,339 ± 10,729 μg/dL u pokusne u odnosu na 190,470 ± 5,775 μg/dL u kontrolne skupine, P>0,05. Nisu ustanovljene statistički značajne razlike između istraživane i kontrolne skupine s obzirom na razine Ca, P i Zn. Zaključuje se da je razvojna ortopedska bolest u ždrjebadi povezana s razinom Cu u serumu. Bakar je važan element za rast ždrjebadi

NMR-based metabolomic evaluation in dairy cows with displaced abomasum

This study is the first to evaluate nuclear magnetic resonance (NMR) -based metabolomics in cows with displaced abomasum (DA), which is an internationally recognized problem in dairy cows. Some biochemical parameters have been used for monitoring DA. However, to date, few data have been available on the blood metabolomic profile of dairy cows. Forty Holstein multiparous cows with DA (30 left, 10 right) and 10 clinically healthy Holstein multiparous cows were the subjects of the study. All the animals had similar dry matter intake. An NMR-based metabolomics approach and hematological and biochemical analyses were performed. Some changes in biochemical parameters were observed between the groups. Among the cows with left displaced abomasum (LDA), 10 were associated with concomitant ketosis. Disease periods between the 2 DA groups were different. The metabolites identified and quantified by NMR analysis were valine, 3 beta-hydroxybutyrate (BHB), alanine, glutamine, glutamate, and succinate. The last of these was significantly decreased in cows with right displaced abomasum (RDA). Glutamine, glutamate, and 3 BHB levels were significantly different between DA groups. There was a positive correlation between BHB and valine, glutamine, and glutamate in the LDA group. Overall, this work suggests that the additional information obtained by NMR-based metabolomics evaluation may contribute to assessing the metabolic status of cows with DA.Scientific and Technological Research Council of Turkey (TUBITAK) [111O545]This work was supported by the Scientific and Technological Research Council of Turkey (TUBITAK, project no: 111O545)

Relationship between the degree of dehydration and the balance of acid-based changes in dehydrated calves with diarrhoea

The aim of the study was to investigate acid-base changes and to determine some serum biochemical parameters in dehydrated calves with diarrhoea according to the degree of dehydratation. Thirty diarrhoeic dehydrated calves submitted to treatment in the university clinic, were used in the study. The calves were accessed as suitable for this study, if they were moderately or severely dehydrated according to clinical symptoms. All sick calves had the usual yellow and watery diarrhoea. Calves with 4% to 8% dehydration (moderate) had a weak suckle reflex, dry mucous membranes, warm mouth and partly good muscular tone. Calves with 10% and above dehydration (severe) were unable to stand, and had no suckling reflex and cold mouth. The mean pH, base excess, chloride (only severely dehydrated group) and sodium were significantly decreased in both moderately and severely dehydrated groups. On the other hand, potassium, phosphorus, HCO3- and anion gap levels were increased, compared to that of the control group. Results of this study showed that there was a relationship between the base excess and anion gap, with a degree of clinical dehydration. However, there may not be an exact correlation between the degree of dehydration and the severity of acidosis. Based on the clinical symptoms, the results of this study could be a useful tool under field conditions, in estimating the base excess in diarrhoeic dehydrated calves, when acidosis therapy is needed

SERUM GASTRIN IN DOGS WITH ACUTE OR CHRONIC GASTRITIS AND POSITIVE OR NEGATIVE FOR HELICOBACTER SP. IN THE STOMACH

Abstract The relationship between gastrin levels and presence of Helicobacter-like organisms (HLO) in dogs with acute or chronic gastritis was investigated. For this purpose, a total of 52 crossbred Kangal Dogs aging 2-5 years were used; including 12 dogs with acute gastritis, 25 dogs with chronic gastritis, and 15 healthy dogs. Blood samples were collected from the vena cephalica. Serum gastrin levels were measured using commercial competitive binding radioimmunoassay. HLO were found in 64%, 58.3%, and 60% of animals with chronic gastritis or acute gastritis, and controls, respectively. The gastrin levels in dogs with chronic gastritis were higher than in those with acute gastritis and controls. There were no significant differences between the gastrin levels in all groups, with regard to HLO positive versus HLO negative dogs. In conclusion, HLO incidence was generally found in high levels in all the dogs. However, HLO did not primarily affect the stomach mucosal damage. In the mean time, there was no relation between the levels of serum gastrin in dogs with gastritis, either being HLO positive or negative. The results of the study showed that higher gastrin levels in dogs with gastritis were related to severe gastric lesions and mucosal damage
