The aim of this study was to present cases of rats with suspected pituitary tumours and the application of computed tomography in diagnosing pituitary tumours in rats. The study included 25 animals with symptoms suggestive of pituitary tumours (ataxia, paralyses, strabismus). The animals were submitted to a detailed clinical examination and computed tomography (CT). The CT confirmed pituitary tumours in 20 out of 25 animals. Additionally, this study enabled the proof of a definite correlation between the size of the pituitary tumour and clinical symptoms observed in sick animals. This article presents the usefulness of tomography examination in diagnosing pituitary tumours in rats and it is the first paper of this kind in Poland. However, it should be borne in mind that a CT without the use of a contrast medium only allows for the identification of neoplasm in some cases. It is the contrast-computed tomography that significantly increases diagnostic chances of this method in identification and evaluation of the size, shape and contour of proliferative lesions of the brain region in rats.
The study objective was to determine reference values of selected biochemical parameters of the haemolymph of Cepaea nemoralis snails (Mollusca, Gastropoda, Helicidae). The study determined the activity of aminotransferases (AST and ALT), which was 11.22 ± 10.92 [u/l] and 6.72 ± 3.18 [u/l], respectively, and alkaline phosphatase (ALP) at a level of 3.92 ± 2.08 [u/l]. The level of amylase (AMY) in the haemolymph was 2.32 ± 0.74 [u/l], while lipase (LIP) was 0.74 ± 0.79 [u/l]. The concentration of urea (UREA) was established at 2.28 ± 0.48 [mg/dl], creatinine (CREA) at 2.28 ± 0.09 [mg/dl], uric acid (UA) at 0.22 ± 0.16 [mg/dl], calcium (Ca) at 21.24 ± 2.4 [mg/dl], and total protein (TP) at 1.38 ± 0.34 [g/l]. The specific gravity of the haemolymph was 1.0 ± 0.002. The haemolymph was obtained from 211 individuals in the active phase collected from their natural habitat. The biochemical parameters of the haemolymph were determined with a BS 180 apparatus (Mindray), and the specific gravity with a refractometer. The article also desrcibes an intravital technique of collecting haemolymph from C. nemoralis. The results obtained may constitute an aid and a guideline for scientists dealing with the physiology of land molluscs.
The aim of this study was to analyse clinical cases of bartonellosis. Medical records of cats naturally infected with Bartonella henselae were retrospectively evaluated with regard to clinical signs and laboratory abnormalities at the time of presentation, therapy and course of disease. The most common clinical abnormalities in B. henselae-positive cats included in the study were flea allergic dermatitis (29.5%), fever (25%) and diarrhoea (12.5%). Thrombocytopenia was the most common laboratory abnormality (50%).The results of the study indicate that B. henselae infection must be considered in differential diagnosis in patients with thrombocytopenia and flea invasion.
Vaccinations for pet rabbits using biological preparations registered in Poland provide protection against three clinical entities: myxomatosis, rabbit haemorrhagic disease types 1 and 2 (RHD1 and RHD2). This article presents an analysis of the number of vaccinations performed in rabbits in the years 2011-2020 at the Clinic of Infectious Diseases of the Faculty of Veterinary Medicine, University of Life Sciences in Lublin. Among the total number of 3304 rabbits admitted to the clinic, 574 visits were for vaccinations, which indicates that the owners of these animals are interested in specific prevention of myxomatosis and RHD. Detailed analysis of the clinic’s records makes it possible to identify certain tendencies, e.g. those associated with the choice of biological preparations or the percentage of immunized animals in different years. Vaccination of rabbits is not difficult for the veterinarian from a technical point of view, it provides excellent protection against lethal infectious diseases, and it can be a source of income for veterinary clinics. For this reason it is worth disseminating knowledge on the vaccination programme for rabbits kept as companion animals among owners of these animals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
