Immunohistochemical and histopathological studies of fixed rabies virus in goats

The purpose of this study was to systematically demonstrate and compare the pathological and immunohistochemical changes in goats which were infected by a fixed rabies virus that was used in vaccine production. In the histopathological examinations, varying degrees of inflammatory, degenerative and necrotic changes were detected in the central nervous system. In the preparations stained by the immunoperoxidase (IP) method, intra- and/or extracellular viral antigens were observed on the cerebellum, cornu ammonis, thalamus, pons, nucleus caudatus, spinal cord, medulla oblongata, Gasserian ganglion, eye and retropharyngeal lymph nodes. In the preparations stained by the immunofluorescence (IF) method, intra- and/or extracellular viral antigens were seen in the same locations with the exception of the retropharyngeal lymph nodes. It was also observed that the antigens were qualitatively and quantitatively well stained with both methods. However, the visibility of antigens in the retropharyngeal lymph nodes and eye, and the facilities of applying made the IP method much more advantageous than the IF method.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.

Detection of progressive and regressive phase and LINE-1 retrotransposon in transfected dogs with transmissible venereal tumor during chemotherapy

WOS: 000445944700005PubMed: 30041285Canine transmissible venereal tumor (CTVT) is a tumor that commonly occurs in genital and extragenital sites of both genders. Long interspersed nuclear elements (LINE-1) retrotransposon has a pivotal role in allogenic transfection among uncontrolled dog populations. This study aimed to perform pathomorphological, immunohistochemical, and in situ polymerase chain reaction (PCR) evaluation of CTVT (n = 18) in transfected dogs during chemotherapy. Immunohistochemically, tumor phases were investigated by using specific markers (CD3, CD4, CD8, CD79, and transforming growth factor beta [TGF-beta]), and investigated an amplified specific sequence of TVT LINE-1 retrotransposon by in situ PCR. Polyhedral-shaped neoplastic cells that had large, round, hypo/hyperchromatic nuclei and eosinophilic cytoplasm were detected. All marker results were positive, especially in the early weeks of recovery. CD4 and TGF-beta markers were conspicuously positive at the initial stage. In situ PCR LINE-1 sequence was initially positive in only four cases. It is believed that the CD and TGF-beta markers provide phase identification at tumor initiation and during chemotherapy. It is thought that presence of T and B lymphocytes, which have roles in cellular and humoral immunity, is needed so that regression of the tumor is possible.Ankara University Scientific Research Projects, Turkey [10B3338008/2014]This study was supported by the Ankara University Scientific Research Projects (project No. 10B3338008/2014), Turkey

Gastrointestinal side effect profile due to the use of alendronate in the treatment of osteoporosis

The aim of our study was to evaluate the upper gastrointestinal (GI) tract side effect profile in 759 female patients that had taken alendronate (10 mg/day), for at least 6 months, for the treatment of osteoporosis, in relation to the safety of alendronate and the compliance of patients to its absorption rules
