Ksanten turevleri, dogal, yari sentetik ve sentetik kokenli olabilen siklik, organik bilesikleri temsil eder. Bu bilesikler, antibakteriyel, antiviral ve antienflamatuar ozellikler gibi cesitli farmakolojik aktiviteler nedeniyle dikkat cekmektedirler. Ayrica, ilaca direncli losemi hatlari icin ve fotodinamik tedavide antagonistler olarak kullanilmaktadirlar. Ayrica lazer teknolojisinde boyalar ve biyomolekullerin gorsellestirilmesi icin pH'a duyarli floresan malzemeler olarak uygulanirlar. Veteriner hekimlik alaninda yeni hastaliklar nedeniyle, bu bilesiklerin uygulanmasi cok faydali olabilir ve literaturde Veteriner arastirma alanindaki benzer bilesiklerin aktivitesi aciklanmaktadir. Bu derlemede ksanten turevlerinin antibakteriyel, antifungal, antihelmintik, antiprotozoal, antikanserojenik ve antidiyabetik aktivite gibi en onemli aktiviteleri ve etki mekanizmalari sunulmustur.

The modern way of cultivation, that is, the technology used for keeping and exploitation of dairy cows, is aimed at continuous increase in the intensity of milk production and maximizing the use of genetically high milk. The burden on the metabolism of high-productive cows is most evident in late gravidity and puerperium. The link between the production characteristics of high-producing dairy cows (daily milk production) and the metabolic capacity of their organism is still insufficiently clear, and so a legitimate reason for the research. The concentration of total cholesterol in the blood serum of cows in lactation varies in a wide range (1.3-9.36 mmol / L). Many internal and external factors affect the elevated or decreased level of total cholesterol concentration in blood serum of lactating cows. According to the recent studies, the amount of daily milk production of cows who lived in farm conditions of breeding and keeping, does not have a significant effect on the level of total cholesterol in the blood serum, what was determined using single linear regression analysis.

Bites of laboratory animals are treated as the bites of any other animals since the possibility of existence of pathogenic microorganisms, unfavorable for human health, in the rooms where these animals reside, is not excluded. A rare case of a laboratory rat bite, used for scientific research and previously infected with Pseudomonas aeruginosa , is presented here. The patient's wound was located on the forefinger of his hand and was 1 cm long and up to 0.2 cm deep. The antitetanus prophylaxis was administered in an ambulance, including antibiotic therapy with amoxicillin-clavulanate per os. There exists a need for checks and special guidelines for the handling and retention of laboratory animals. The patient has successfully remedied the wound, thanks to consistent antibiotic therapy and antitetanus prophylaxis, and possible inflammatory complications were prevented .

Cytological analysis of urine sediment is an integral part of urine analysis and a useful, cost-effective diagnostic tool for all routine clinical examinations, which can sometimes be overlooked in veterinary practice. Proper handling and timely urine sample analysis are essential for valid microscopic analysis. Microscopic urinary sediment testing is usually carried out with stained or unstained specimen. A common urine may contain a small number of cells (erythrocytes and leukocytes, epithelial cells) of several crystals, spermatozoids (male animals). In contrast, a large number of cells or casts, the presence of unusual types of crystals, neoplastic cells, parasites, and microorganisms include abnormal findings, requiring a specialized diagnostic approach. Correct identification of organic components of the urinary sediment are crucial for accurate and timely diagnosis of kidney disorders. Laboratory experts should be trained to properly identify and classify organic components of the urinary tract.

Post-traumatic osteomyelitis (OM) is an uncommon event in cats, usually affecting distal phalanges of extremities. Tail injuries seldom cause bone infection, but often result in neural damage with subsequent tail paralysis, and occasionally in urinary/fecal incontinence. We present a case of old stray cat which developed post-traumatic tail OM, and endured it for years. It was an immuno-compromised, neglected, animal strongly infested with larvae of Aelurostrongylus abs trusus and oocistae of Isospora felis. Ultimately, it was treated by tail amputation, with without any health consequences.  Relevance and novel information: This report describes the management and outcome of a rare and a life-threatening case of feline post-traumatic  tail OM which was previously not reported in literature.
