    Opis:
    The changes in the milk composition and its lipid fraction during the rearing of lambs in non-milked sheep. Studies regarding the effect of lactation stage on milk content and lipid fraction composition are mostly conducted on milked animals. The aim of this study was to analyze the changes in the basic milk composition and content of fatty acids in the fat fraction during the rearing of lambs in non-milked sheep. The study was carried out on 22 ewes of Polish lowland sheep of Żelazneńska strain, which reared lambs sold at low weight classes (up to 22 kg). Milk samples were collected at 10 (period 1), 25 (period 2) and 52 (period 3) days of lactation. There were no differences in the amount of the basic components of milk in the studied periods of lactation beside the fat (P≤ 0.05) content. There were also no difference in the content of fatty acid groups in the fat fraction of ewe’s milk examined at 10, 25 and 52 day of lactation.Although,in the third period of lactation, the content of saturated fatty acids (SFA) was slightlyhigher compared to first period. In turn, the content of oleic acid (P≥0.30) and C18:3 (P≤ 0.05) was higher in the 10 day of rearing then in 52 day. A slightly larger share of essential C18 unsaturated fatty acids in ewe’s milk in early lactation may suggest the involvement of adipose tissue in the formation of milk fat.
    Zmiany w składzie mleka i jego frakcji tłuszczowej w trakcie odchowu jagniąt u owiec nieużytkowanych mlecznie. Badania dotyczące wpływu laktacji na składniki mleka i skład frakcji lipidowej są w większości prowadzone na zwierzętach użytkowanych mlecznie. Celem tych badań było przeanalizowanie zmian w podstawowym składzie mleka i w zawartości kwasów tłuszczowych w jego frakcji tłuszczowej w trakcie odchowu jagniąt u owiec nie doskonalonych w kierunku użytkowania mlecznego. Badania prowadzono na 22 maciorkach nizinnych odmiany żelazneńskiej, które odchowywały jagnięta sprzedawane w niskich standardach wagowych (do 22 kg). Próby mleka pobierano w 10 (okres 1), 25 (okres 2) i 52 (okres 3) dniu laktacji. Nie znaleziono różnic w zawartości podstawowych składników mleka w badanych okresach laktacji, oprócz zawartości tłuszczu. Różnice nie występowały także w zawartości grup kwasów tłuszczowych w frakcji tłuszczowej mleka maciorek badanych w 10, 25 i 52 dniu laktacji. Chociaż, zawartość nasyconych kwasów tłuszczowych (SFA) była nieznacznie większa w trzecim okresie laktacji w porównaniu z okresem pierwszym. Z kolei zawartość kwasu oleinowego (P≥ 0,30) i C18:3 (P≤ 0,05) była większa w 10 dniu odchowu jagniąt niż w 52 dniu. Niewiele większy udział niezbędnych nienasyconych kwasów tłuszczowych C18 w mleku maciorek we wczesnej laktacji może sugerować zaangażowanie tkanki zapasowej w tworzenie tłuszczu mleka.

    Opis:
    Large granular lymphomas (LGLs) comprise a specific group of lymphomas regardless of classification scheme. An LGL consists of cells that show less or more mature morphology, but typically neoplastic cells possess cytoplasmic azurophilic granules clearly visible during cytological examination. The aim of the present study was to present clinical and cytological data on large granular lymphomas in cats and to analyses the therapeutic responses in treated cases. During the period from 2012 to 2014 six cats were as having large granular lymphoma. In one cat a nasal form of LGL was recognized, a systemic form was recognized in another cat, and in four cases an alimentary form was recognized. Cellular samples for cytopathology were collected from the cat with nasal cavity mass, from the enlarged mandibular lymph node and thoracic cavity from second cat, and in four cats from the abdominal mass during ultrasound-assisted fine-needle biopsy. Therapy was introduced in 5 of the 6 cats. In two cases palliative therapy with glucocorticoids was conducted, in two cases chemotherapy with COP protocol, and therapy with masitinib in one case. The median of survival time for cats treated with anticancer therapy was 9 months, the median of survival time for cats treated with glucocorticoids was 1.5 months. In conclusion, large granular lymphomas, especially the alimentary form, are a relatively common type of lymphoma in cats. Simple diagnostic methods such as clinical examination, imaging techniques and routine cytology are sufficient in majority of cases. Despite aggressive behavior and poor general prognosis, conventional chemotherapy lead to a good response in some treated cats regardless of anatomic form and histologic grade of malignancy.

    Opis:
    Malignant lymphomas are one of the most common malignant tumours occurring in dogs. The basic method of lymphoma diagnosis in human, as well as in canine oncology is histopathology supported by immunohistochemistry. It was suggested that in veterinary medicine excisional biopsy of lymph node and histopathology should be considered only where the cytologic diagnosis is equivocal or needs to be confirmed. There are at least three basic reasons for which cytological examination ought to be accepted as a sufficient and reliable diagnostic method for lymphoma in dogs. Firstly, most dog owners consider the fine-needle biopsy as an acceptable non-harmful method of sample collection. Secondly, an increasing number of studies recommend cytology as an accurate test for diagnosing and subtyping canine lymphoma. Finally, the vast majority of canine lymphoma subtypes belong to 4-5 categories characterized by a typical cytological picture. Immunocytochemical staining of cytological smears gives new diagnostic possibilities, such as detection of markers better characterizing given growth or a potential goal for target therapy in individual cases (for example inhibitors of platelet-derived growth factor).

    Opis:
    Feline injection site sarcomas (FISS) are malignant neoplasms of mesenchymal origin which arise in sites of injections in cats. The prevalence is estimated between 1 in 1000 and 1 in 10 000 vaccinations in the United Kingdom. The aim of this study was to estimate the incidence of FISS in Poland and to analyse clinical aspects and histological and cytological features of injection site sarcomas. In our study the prevalence of FISS was 0.16% (16 FISS on 10.000 of cats) in feline patients in one of a veterinary surgery which conducts the general practice and 85 on 10.000 cats in a practice focused on veterinary oncology. The most typical microscopic features of FISS found in the present analysis were: the presence of perilesional scarring and inflammation, aggregates of lymphocytes at the tumour periphery, moderate but usually marked cellular pleomorphism and intralesional necrosis. The most typical cytologic features of FISS found in present study were: the presence of neutrophils, marked cellular pleomorphism, the presence of lymphocytes and macrophages, the presence of extremely large nuclei in the neoplastic cells, and high sample cellularity.

    Opis:
    The objective of the study was to perform micromorphological analyses of the secretory structures of leaves and stems of oil-bearing industrial plants from the Lamiaceae family such as lemon balm (Melissa officinalis L.), peppermint (Mentha × piperita L.), sage (Salvia officinalis L.), marjoram (Origanum majorana L., syn. Origanum dubium Boiss.), rosemary (Rosmarinus officinalis L.) and common thyme (Thymus vulgaris L.) using light microscope and scanning electron microscope. In addition, an estimation of the content of volatile substances in the plant species under study was performed using GC-MS, as well as the qualitative and quantitative analysis of essential oil, that is an important component in terms of the estimation of raw material applicability for use in the industry. In the epidermal cells of studied plants, 2 types of Lamiaceae-type glandular trichomes were identified: short- and long-stalked capitate glandular trichomes with single- and bicellular secretory capitulum, and peltate glandular trichomes with eight- and over a dozen-cell secretory capitulum. Capitate trichomes were densely distributed on the surface of the epidermis, while peltate trichomes were sparse, though regular, and were situated in depressions. Glandular trichomes were found more frequently on leaves than on stems. The cuticle of the abaxial of leaf was characterized in most cases by the occurrence of larger average diameter peltate trichomes compared to the cuticle of the adaxial side of leaf. Peppermint produced the largest structures accumulating essential oil on the leaves (average diameter of peltate trichomes – 78.48 µm on the adaxial side of leaf, up to 96.43 µm), while on the stem, the highest average diameter of the peltate trichomes was observed in sage (an average of 75.53 µm, up to 85.99 µm). The lemon balm was characterized by the presence of capitate and peltate trichomes with the smallest diameter (an average of 44.26 µm). Lemon balm was characterized by the greatest density of glandular trichomes compared to other plant species. Among the plants studied, the highest content of oil was noted in the case of thyme and peppermint (2.22% and 2.20% v/w, respectively), and the lowest in green parts of lemon balm (0.17% v/w). The isolated essential oils contained predominantly components from the groups of monoterpenes and sesquiterpenes, and it is the presence of those substances that determines the possibility of utilizing the plants studied for a variety of purposes.

    Opis:
    Ventricular tachycardia may lead to haemodynamic deterioration and, in the case of long term persistence, is associated with the development of tachycardiomyopathy. The effect of ventricular tachycardia on haemodynamics in individuals with tachycardiomyopathy, but being in sinus rhythm has not been studied. Rapid ventricular pacing is a model of ventricular tachycardia. The aim of this study was to determine the effect of rapid ventricular pacing on blood pressure in healthy animals and those with tachycardiomyopathy. A total of 66 animals were studied: 32 in the control group and 34 in the study group. The results of two groups of examinations were compared: the first performed in healthy animals (133 examinations) and the second performed in animals paced for at least one month (77 examinations). Blood pressure measurements were taken during chronic pacing - 20 min after onset of general anaesthesia, in baseline conditions (20 min after pacing cessation or 20 min after onset of general anaesthesia in healthy animals) and immediately after short-term rapid pacing. In baseline conditions significantly higher systolic and diastolic blood pressure was found in healthy animals than in those with tachycardiomyopathy. During an event of rapid ventricular pacing, a significant decrease in systolic and diastolic blood pressure was found in both groups of animals. In the group of chronically paced animals the blood pressure was lower just after restarting ventricular pacing than during chronic pacing. Cardiovascular adaptation to ventricular tachycardia develops with the length of its duration. Relapse of ventricular tachycardia leads to a blood pressure decrease more pronounced than during chronic ventricular pacing.
