Öğe Disseminated intravascular coagulation in cattle with abomasal displacement(KLUWER ACADEMIC PUBL, 2005) Irmak, K; Turgut, KThe purpose of the study was to evaluate haemostatic function in cattle with abomasal displacement (AD) and to reflect the occurrence of disseminated intravascular coagulation (DIC). Ten adult cattle with left displacement of abomasum (LDA) (group I), 10 adult cattle with right displacement of abomasum with volvulus (RDA) (group II) and 10 clinically healthy adult cattle (control group) were used as material. Numbers of platelets (PLT) and coagulation tests (activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), serum fibrin/fibrinogen degradation products (FDPs), fibrinogen) were measured before the surgical treatment of cattle with LDA and RDA. APTT was prolonged only in group II compared with the control and group I (P<0.05). However, when the individual values of coagulation profiles of each cow were evaluated, two cattle in group I and three cattle in group II had at least three abnormal coagulation profiles, which reflect the occurrence of DIC. These cattle died after surgical treatment. The two cattle with LDA had abnormal APTT, FDPs and PLT values; three cattle with RDA had abnormal APTT, PT, TT, FDPs and PLT values. APTT (5 cases), FDPs (5 cases) and thrombocytopenia (5 cases) were the three most common abnormal tests on coagulation profile in the cattle with LDA and RDA. The results of the study indicate that cattle with AD had a spectrum of haemostatic dysfunction and that DIC was a significant risk factor for mortality.Öğe The evaluation of coagulation profiles in calves with suspected septic shock(SPRINGER, 2006) Irmak, K; Sen, I; Col, R; Birdane, FM; Guzelbektes, H; Civelek, T; Yilmaz, AThe purpose of the study reported here was to evaluate the haemostatic function in calves with suspected septic shock and to reflect the occurrence of disseminated intravascular coagulation (DIC). Twenty-six calves suspected of having septic shock (experimental group) and 10 clinically healthy calves (control group) were used. On admission, the experimental group of calves had been ill for an average of 2 days. Therapy was applied to the experimental group of calves. The packed cell volume (PCV), haemoglobin (Hb), white blood cell (WBC), red blood cell (RBC) and platelet (PLT) counts were determined. Blood smears for toxic neutrophil and schistocyte intensity were evaluated. For the coagulation profile, plasma activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), fibrinogen and fibrin/fibrinogen degradation products (FDPs) values were determined. Toxic neutrophils in blood smears were observed in 12 calves of the experimental group. APTT was prolonged in the experimental group compared with the control group (p < 0.05). Fibrinogen concentration was found to be higher in the experimental group than in the control group (p < 0.001). Total leukocyte counts were higher in the experimental group compared with the control group (p < 0.01). Platelet counts in the experimental group were lower than the control group (p < 0.001). However, when the individual values of coagulation profiles of each calf were evaluated, 8 calves had at least three abnormal coagulation profiles (APTT > 72 s, PT > 34.5 s, TT > 33.7 s, FDPs > 5 mu g/ml, PLT <= 150 x 10(3)/mm(3)) and abnormal erythrocyte morphology (schistocytes >= 1). The most common abnormal tests in the coagulation profile were APTT and PT (7 cases), FDPs (6 cases), thrombocytopenia (4 cases), and schistocytes in blood smears (8 cases) in these 8 calves. The results of this study indicate that DIC might be a significant risk factor for mortality in calves with suspected septic shock.Öğe The prevalence of Cryptosporidium parvum infection in the diarrhoiec and non-diarrhoeic calves(ECOLE NATIONALE VETERINAIRE TOULOUSE, 2003) Sevinc, F; Irmak, K; Sevinc, MFaeces samples from 300 diarrhoeic and non - diarrhoeic calves were screened for the presence of Cryptosporidium infections. The prevalence of Cryptosporidium. parvum was determined by using acid-fast staining method (Ziehl Neelsen) and ELISA kit. Calves were grouped according to their age as follows: 1-10, 10-20, 20-30, 30-45 and > 45 days. The prevalence of infection in diarrhoeic and non diarrhoeic calves was 63.92% and 9.85%, respectively. Cryptosporidium infection was detected in 50.75%, 35.71%, 25.45%, 14.71% and 13.24% of the calves in the age groups, respectively.Öğe Serum GGT and ALP enzyme activities in calves with failure of passive transfer of antibody(INDIAN VETERINARY JOURNAL, 2003) Sevinc, M; Sen, I; Irmak, K; Turgut, K[Abstract not Available]Öğe Vitamin levels in premature and newborn calves(INDIAN VETERINARY JOURNAL, 2005) Irmak, K; Haliloglu, S[Abstract not Available]
