Hematologic, Blood Gas, Cardiac Biomarkers and Serum Biochemical Parameters in Calves with Atresia Coli and Theirs Relationship with Prognosis

Hasan GÜZELBEKTEŞ

Background: Atresia coli is an intestinal anomaly. Generally, absence of defecation in calves less than 10 days old, diminishing appetite, progressing abdominal distention and time-developing depression are reported in atresia coli. Although a calf consumes its milk normally in first days, loss of appetite develops over time. Occasional minor pain indications are observed. The objective of this study was to evaluate of hematologic, blood gases, cardiac biomarkers and serum biochemical parameters before operation in calves with atresia coli, and to investigate relationship with prognosis of the ...More

Quantification of Mitral Regurgitation in Anatolian Shepherd Dogs with Asymptomatic Degenerative Mitral Valve Disease

Hasan GÜZELBEKTEŞ

Degenerative mitral valvular disease (DMVD) is the most frequent cardiac disease, causing mitral regurgitation (MR) in dogs. The purpose of this study was to compare the ratio of the regurgitant jet area (RJA) to the left atrial area (LAA) (RJA/LAA) with subtracting method to quantify regurgitant volume (RegV) and regurgitant fraction (RF) in asymptomatic Anatolian Shepherd Dogs (ASHs) with DMVD. Thirty-eight ASHs with DMVD were used as experimental group. The control group consisted of 35 healthy ASHs. In 38 ASHs with DMVD (20 B1 dogs and 18 B2 dogs), the severity of MR was assessed by RJA/L ...More

Cardiac biomarkers in premature calves with respiratory distress syndrome

Hasan GÜZELBEKTEŞ

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 ...More

Comparison of Instilled Lidocaine and Procaine Effects on Pain Relief in Dogs Undergoing Elective Ovariohysterectomy

Hasan GÜZELBEKTEŞ

The aim of the present study was to compare the analgesic efficacy of instilled intra-peritoneal lidocaine and procaine during the perioperative and the postoperative periods in dogs undergoing elective ovariohysterectomy (OVH). Twenty-four sexually intact female dogs were referred for OVH. Following the laparotomv procedure the L group received intraperironeal instillation of 3.5 mg/kg of 0.2% lidocaine. The therapeutic agent was administreted over the area of ovaries, broad ligament, and uterine stump. It was injected using a syringe and needle (23 G). The P group administered intraperitonea ...More

Echocardiographic assessment of left ventricular systolic function in neonatal calves with naturally occurring sepsis or septic shock due to diarrhea

İsmail ŞEN | Hasan GÜZELBEKTEŞ

Sepsis is associated with clinically relevant cardiovascular changes. The objectives of this study were to evaluate the clinical value of echocardiography for monitoring left ventricular (LV) systolic function in septic calves. A prospective longitudinal study was performed using a convenience sample. Twenty septic calves and 10 healthy calves were enrolled in the study. Arterial blood pressure (BP) was measured and M-mode echocardiography performed to characterize LV systolic function; the latter included measurement of ejection fraction, EF; stroke volume, SVI and cardiac output indexed to b ...More

Effect of colostrum composition on passive calf immunity in primiparous and multiparous dairy cows

Hasan GÜZELBEKTEŞ

The aim of this study was to determine the effect of colostrum quality and composition on passive calf immunity in primiparous and multiparous dairy cows. Twenty-four primiparous and 24 multiparous dairy cows were used in this study. Calves born from primiparous dairy cows comprised the first group and calves born from multiparous dairy cows constituted the second group. After birth, colostrum samples were immediately taken from dairy cows. Venous blood samples were collected from the calves before the first colostrum intake and on the 2nd, 7th, 14th and 28th days after the first colostrum int ...More

Effect of combinations of intravenous small-volume hypertonic sodium chloride, acetate Ringer, sodium bicarbonate, and lactate Ringer solutions along with oral fluid on the treatment of calf diarrhea

Hasan GÜZELBEKTEŞ

The aim of this study was to compare effect of combinations of intravenous isotonic sodium bicarbonate (NaHCO3), acetate Ringer, lactate Ringer and small-volume hypertonic sodium chloride (NaCl) solutions along with oral electrolyte solutions (OES) on the treatment of neonatal calf diarrhea with moderate dehydration and metabolic acidosis. Thirty-two calves with diarrhea were used in the study. Calves were randomly assigned to receive acetate Ringer solution (n=8), lactate Ringer solution (n=8), isotonic NaHCO3 (n=8) and 7.2% saline solutions (n=8), and two liters of OES were administrated to ...More

Clinical importance of lipid profile in neonatal calves with sepsis

Hasan GÜZELBEKTEŞ | İsmail ŞEN

In this study, it was aimed to determine of diagnostic importance of blood lipid levels in neonatal calves with sepsis. The study was carried out on a total of 70 calves, 60 with sepsis and 10 healthy calves. The calves with sepsis were included in the study, according to clinical and hematological findings. The blood samples were taken from the V. jugularis for hematological, lipid profile and biochemical analyzes after the routine clinical examinations of the calves. There were significantly (P < 0.05) decrease in body temperature, increase in respiration rate and capillary refill time in th ...More

Venous lactate, pH and partial pressure of carbon dioxide levels as prognostic indicators in 110 premature calves with respiratory distress syndrome

Hasan GÜZELBEKTEŞ

Hyperlactatemia, hypercapnia, low pH and low oxygen saturation (SatO(2)) are commonly observed in premature calves. These clinical indicators are associated with increased mortality in preterm human newborns with respiratory distress syndrome (RDS). The aim of this study was to investigate the prognostic importance of venous pH, partial pressure of carbon dioxide (pCO(2)) and lactate level and which parameters are related with mortality in premature calves with RDS. All premature calves (52 male/58 female) were admitted to clinic within 12-24 hours after birth and blood samples were also taken ...More

Seasonal evaluation of skeletal muscle damage and hematological and biochemical parameters of Greco-Roman wrestlers from the Kyrgyzstan national team before the 2016 Summer Olympic Games

Bilal DEMIRHAN | Kanat CANUZAKOV | Hasan GÜZELBEKTEŞ

BACKGROUND: Regular exercise activities affect blood cells. OBJECTIVE: The purpose of this study was to evaluate the seasonal evaluation of some hematological and biochemical parameters of the Olympic Greco-Roman wrestlers. METHODS: A total of 3 measurements were performed on wrestlers: immediately before the training period, three months and six months after the training session. Hematological and biochemical parameters were analyzed by taking sufficient blood samples from the athletes before and after exercise. RESULTS: The total leukocyte, lymphocyte, and neutrophil values were found to be ...More
