ABSTRACT. An eighteen month old female Doberman pinscher dog was referred to teaching hospital of Adnan Menderes University, Faculty of Veterinary Medicine with the complaint of right forelimb lameness for a month. On the basis of clinical, radiographical, scintigraphical, computed tomographical and histopathological findings, aneurysmal bone cyst was diagnosed. Surgical curettage and bone cement treatment were applied. The patient recovered after 12 months. This case proves that aneurysmal bone cyst, without osteolysis and/or damages to the surrounding tissues, may result in a good prognosis if curettage and treatment with bone cement are done. KEY WORDS: aneurysmal bone cyst, bone cement, canine.

The aim of this study was to induce Lactococcus garvieae infection in young and adult fish through different routes [intraperitoneal (IP) and immersion (IM)] and to investigate the pathogenesis and histopathological and immunohistochemical findings comparatively. For this purpose, a total of 180 rainbow trout (90 young, 20 ± 5 g and 90 adult, 80 ± 10 g) obtained from a commercial fish farm were used. The fish were divided into eight groups, four experimental groups (Young-Adult IP groups and Young-Adult IM groups, each contain 30 fish) and four control groups (Young-Adult IP Control groups and Young-Adult IM control groups, each contain 15 fishes). The experimental study was conducted using L. garvieae, and confirmatory identification was performed by PCR. The sequence result of the PCR amplicon of 16S rDNA from isolate L. garvieae LAC1 was determined and deposited in the GenBank database under accession number KC883976. Fish in the IP groups were intraperitoneally administered an inoculate containing 10(6) cfu mL(-1) bacteria 0.1 mL. In the IM groups, fish were kept in inoculated water containing 10(8) cfu mL(-1) bacteria for 20 min. Mortality as well as clinical and pathological findings was recorded daily, and significant differences in macroscopic and microscopic results were observed between the IP and IM administration groups. All tissue samples were immunohistochemically stained by the avidin-biotin-peroxidase complex and immunofluorescence (IF) methods using polyclonal antibody to detect L. garvieae antigens. In immunoperoxidase staining in the IP groups, positive reactions to bacterial antigens were most commonly seen in the spleen, kidney, heart, liver, peritoneum and swim bladder. In the IM groups, bacterial antigens were most commonly found in the eye, gill, spleen and kidney. In the IF method, the distribution of antigens in tissue and organs was similar to the reactions with immunoperoxidase staining. Finally, in this experimental study, an important correlation was seen between the distribution of L. garvieae antigens and lesions developing in many organ and tissues.

The aim of this study was to investigate the protective effects of silymarin (SLY) and curcumin (CUR), which have strong antioxidant properties, against the toxic effects of high dose of cyclophosphamide (CP) on the liver and kidneys of rats. For this purpose, a total of 36 adult Wistar albino female rats at the weight of, 250±10 g were used. Biochemical parameters were found to be significantly higher in the CP-only group than in the other groups. In the groups in which SLY and CUR were administered concurrently with CP, biochemical parameters were found to be significantly lower than in the CP-only group. In the SLY+CP and CUR+CP groups, biochemical parameters were correlated with the severity of histopathological findings. In genotoxic examination, the comet parameter levels in the SLY+CP and CUR+CP-treated groups were lower than those in the CP-treated group. The present study established that both SLY and CUR are effective against the toxic effects of high doses of CP. Keywords
