    Hematological, serum biochemical results, and treatment approach of an Arabian mare with squamous cell carcinoma of the vulva - case report
    (Arquivo Brasileiro Medicina Veterinaria Zootecnia, 2022) Safak, T.; Yilmaz, O.; Risvanli, A.; Akdeniz-Incili, C.
    A 20-year-old Arabian mare, was brought to the obstetrics and gynecology clinic with the complaint of an unknown wound in the genital area. Although the mare's general condition was good, examination of the genital area revealed a wide-open wound in the vulva and posterior vagina, characterized by fibrotic growth. The biopsy sample was sent to the pathology laboratory. A diagnosis of squamous cell carcinoma (SCC) was made after histopathological examination. Blood samples for serum biochemistry and hematological tests were collected from the jugular vein. Hematological and serum biochemical findings are generally used to diagnose diseases in animals and humans. Hematological and serum biochemical findings are important with genital SCC. Therefore, the findings of these values are given in this case report.

    Investigation of Changes in Biochemical Parameters in Some Diseases Occurring During the Transition Period in Simmental Cows
    (Israel Veterinary Medical Assoc, 2023) Safak, T.; Yilmaz, O.; Risvanli, A.
    The transition period is important in cows. This study was conducted to evaluate the effects of retained fetal membranes (RFM), clinical mastitis, and metritis on biochemical and selected mineral levels in Simmental cows. Cows were divided into five groups; cows with RFM (n=17), clinical mastitis (n=25), metritis (n=21) and postpartum healthy cows (n=21) within 21 days postpartum, and also prepartum healthy cows (n=20) in the 15 +/- 5 days before the expected parturition date. The activity of alkaline phosphatase (ALP) (85.18 +/- 15.83 U/L), aspartate transaminase (AST) (123.02 +/- 19.15 U/L), and gamma-glutamyl transferase (GGT) (28.18 +/- 2.66 U/L) in the metritis group increased compared to the prepartum healthy cows. Moreover, GGT (41.83 +/- 14.61 U/L) and a myocardial band of creatine kinase (CK-MB) (155.25 +/- 27.85 U/L) activities were highest in the RFM group, while creatine kinase - N-acetyl-cysteine activity (CKNAC) (540.45 +/- 157.67 U/L) and creatinine concentration (2.29 +/- 0.88 mg/dL) were observed in the metritis group. Total protein (6.39 +/- 0.38 g/dL) concentration was highest in the case of mastitis. Urea, on the other hand, was highest in the metritis group with a concentration of 61.40 +/- 17.38 mg/dL. Our results showed changes in the biochemical profile of cows with RFM, clinical mastitis, and metritis. Biomarker profiles were determined using receiver-operator characteristic (ROC) curves. It was determined that activities of = 89 (U/L) AST, = 24 (U/L) GGT, and = 106 (U/L) CK-MB for metritis, = 21(U/L) GGT for RFM, and = 105 (U/L) CK-MB for mastitis can be used in the preliminary diagnosis. Also, further studies with a larger cow cohorts are recommended.
