The study presents a comparison of the results received from dogs with dilated cardiomyopathy (DCM) that died during the first 30 d of observation and from dogs with DCM that survived the first 30 d after the ECG. No differences were noted in the duration of QT or QTc in healthy dogs and dogs with DCM. QTcd was significantly higher in dogs with DCM and in dogs with DCM, which did not survive over...
The KHV free carp were experimentally infected with CyHV-3 suspension by immersion at temperatures of 18°C±1 and 25°C±1. Skin, brain, gills, liver, spleen, kidneys, and leukocytes were investigated for the presence of KHV DNA, and sera for the presence of antibodies against the virus. Similar investigations were performed with non-infected carp, designed as control groups. The results of KHV DNA detection...
The aim of this study was to assess the safety of a new vaccine, containing soluble parasitic antigen (SPA), against canine babesiosis. Fifteen dogs were included in the experiment. Five controls received only the adjuvant and 10 dogs were vaccinated with Babesia canis canis SPA twice, at a two weeks interval. For the whole period of the study all animals were under constant clinical observation....
The aim of this study was to investigate the presence of progesterone receptors in hippocampal neurons of male rabbits and the distribution of these receptors in different areas of the hippocampus. The examinations were carried out on brains of five males, New Zealand breed, age of 2 years, weighing 2-3 kg. Immunohistochemical detection of receptors was performed using DAKO LSAB + Kit Peroxidase method...
The distribution pattern of CART- like immunoreactive (CART-LI) nerve structures was studied by a double immunofluorescence technique in the circular muscle layer, myenteric (MP), outer submucous (OSP), and inner submucous plexuses (ISP), as well as in the mucosal layer of porcine descending colon under physiological conditions and during proliferative enteropathy (PE). In control animals, CART-LI...
Blood samples were collected from horses in four time points of the spring-winter training season, according to the difference in effort intensity characteristic for each period. Serum contents of glucose, cholesterol, and creatinine, as well as activity of creatine kinase, aspartate and alanine aminotransferases, and alkaline phosphatase were determined. Training did not cause muscle damage, and...
The studies involved gilts 6 weeks pre-partum allocated into the control and experimental groups. The experimental group received vitamin C at the dose of 2.5g/100 kg b.w./day. Faeces for analyses were collected for 3- and 6- week period of vitamin C dietary inclusion. The faecal material underwent quantitative and qualitative bacteriological evaluation. The count of Enterobacteriaceae was evaluated...
High plasma urea nitrogen concentration has been proposed as an important factor contributing to the decline in reproductive parameters of domestic animals. The aim of this study was to evaluate the effect of urea on the development of preimplantation embryos in a mouse model. During in vivo tests, acute renal failure (ARF) accompanied by hyper-uraemia was induced by intramuscular administration of...
Unbiased stereological methods were used to examine and compare morphometrically the geniculate bodies (GB) in representatives of four mammalian orders (Insectivora, Rodentia, Lagomorpha, and Carnivora). The significant disproportion was observed between the relative sizes of both geniculate nuclei and their neuronal populations in the common shrew and the bank vole. The medial geniculate body (MGB)...
The paper assesses the treatment of cutaneous fungal infection in young beef cattle caused by Trichophyton verrucosum using orally administered zinc sulphate for 28 d at 2 g per animal per day and subcutaneous application of 2.5 mg/kg levamisole administered three times every 7 d. The study was conducted on animals at the age of 110 to 122 d, which were divided into two experimental groups: group...
The experiment was conducted on lambs of the Polish Lowland sheep (PLS) and a synthetic BCP line. The redox potential was assessed in blood of lambs with different genotype and sex, which were fed feed mixtures with various contents of a protein- xanthophyll (PX) concentrate from alfalfa (1.5% and 3%). The 1.5% addition of PX concentrate to feed stimulated the response of the antioxidant defence mechanisms...
The isolates of Staphylococcus aureus strains were examined phenotypically by cultural features, tube coagulase test and clumping factor (CF), and genotypically by conventional PCR. The strains had positive reaction in CF test, but were negative in tube coagulase test. The analysed strains from the same cows in each year expressed also nuc and coa genes. About 25% of the strains were examined by the...
The aim of the work was to determine the concentration of serum cystatin C and usability of its measurement in diagnostics of renal failure in cats. The reference point was the value of glomerular filtration rate (GFR), calculated on the basis of plasma clearance of iohexol (Pcio). Seventy cats were divided into two groups: group I - 24 healthy cats, group II - 46 cats affected with renal dysfunction...
The aim of the study was to investigate gender-specific effects of a maternal treatment with dexamethasone (DEX) at multiple maximum therapeutic doses during the last 25 d of pregnancy on the bone tissue metabolism in neonatal piglets. BMD and BMC were measured. The geometry, histomorphometry, and mechanical properties of bones were determined. The assessment of selected hormones, cytokines, and amino...
The aim of the study was to evaluate interrelationships between final body weight, and morphometric, densitometric, and mechanical properties of the mandible in 6-month-old Polish Large White pigs exposed to dexamethasone and nanocalcium. The study was performed on 27 males, castrated on the 28th d after weaning, and reared until the age of 6 months, after which the animals were slaughtered, and the...
The aim of this study was the morphological characterisation of glioblastoma multiforme tumour grown in ovo. Tumour cells (U-87 MG) were implanted on the chorioallantoic membrane of chicken egg. The structural features of cultured tumours resembled the spontaneous glioblastoma multiforme; however, the differences were also indicated. Our results confirm applicability of in ovo culture in tumour genesis...
The aim of the presented study was to determine whether pulmonary barotrauma without pneumothorax affects the parameters of acid-base balance. The experiment was conducted on rabbits divided into experimental and control groups. The animals from the experimental group were subjected to compression in the hyperbaric chamber and pulmonary barotrauma was induced using a method developed by authors. The...
The paper describes the data concerning rabies in domestic animals and in wildlife as well as in bats in Poland in 2009 and 2010. Analysis of rabies situation was based on species involved and geographical distribution of rabies outbreaks. Favourable decreasing trend in rabies epidemic in 2009 was stopped by the outbreak of rabies in the Malopolska province in 2010. This resulted in dramatic increase...
For 24 weeks, rabbits were fed feed containing non-oxidised or oxidised rapeseed oil. At the beginning of the experiment and even six weeks the rabbits were weighed and blood was taken. After the experiment was completed, their liver was dissected for biochemical and histological examinations. The activity of alanine aminotransferase, aspartate aminotrasferase, glutamate dehydrogenase, sorbitol dehydrogenase,...
The aim of the study was to determine the effect of the limitation of energy intake by restrictive dry matter intake in the far- off part (from -56 d to -22 d) of dry period on the colostrum quality and the calf immunological status. Thirty-eight Polish Holstein- Friesian Black and White multiparous cows and their calves were randomly allotted to one of the two dietary treatments in the far-off period...
