The impact of aging and physical training on angiogenesis in the musculoskeletal system.

Angiogenesis is the physiological process of capillary growth. It is strictly regulated by the balanced activity of agents that promote the formation of capillaries (pro-angiogenic factors) on the one hand and inhibit their growth on the other hand (anti-angiogenic factors). Capillary rarefaction and insufficient angiogenesis are some of the main causes that limit blood flow during aging, whereas physical training is a potent non-pharmacological method to intensify capillary growth in the musculoskeletal system.

Thrombocytopenia as a characteristic trait in the Polish ogar dog.

The study was undertaken to ascertain if the normal thrombocyte count in Polish ogar dog differs from normal values in other dog breeds. The reason for this study was constatation that during routine blood analysis in healthy Polish ogar dogs, thrombocytopenia, not related to the clinical state of the animals, was frequently encountered. The study was carried out on 38 Polish ogar dogs.

Endoscopy and histopathology in the examination of the nasal cavity in dogs.

Nasal diseases of chronic nature are a common clinical complaint in canine practice. However, precise diagnosis in these cases is often difficult and require the use of various, additional diagnostic methods. The aim of this study was to estimate the occurrence of diseases of the upper respiratory tracts in dogs, and to evaluate the usefulness of endoscopy in the diagnostic process as a method of obtaining a final diagnosis.

TransEndoscopic Gastric SubMucosa Islet Transplantation (eGSM-ITx) in pigs with streptozotocine induced diabetes - technical aspects of the procedure - preliminary report.

Background: Islets and pancreas transplantation have become standard treatments of patients with diabetic complications. However pancreas transplantation is associated with high incidence of complications and the long-term results of islet transplantation are still unsatisfactory. Loss of pancreatic islets grafts is caused not only by immunological reactions but also due to the site of grafting and IBMIR.

The diagnosis of gastritis and helicobacter-like organisms infection in endoscopic biopsies of the canine gastric mucosa.

The aim of this study was to evaluate the prevalence of gastric Helicobacter-like organisms (GHLO) and gastritis in the gastric mucosa of dogs with gastric disorders. Tissue samples of the gastric mucosa were obtained from 30 dogs with gastrointestinal symptoms (vomiting, abdominal pain or discomfort, loss of appetite) during endoscopy. Histopathological examinations were performed and occurrence of GHLO infection, gastritis and other mucosal changes were estimated.

Influence of naturally acquired feline leukemia virus (FeLV) infection on the phagocytic and respiratory burst activity of neutrophils and monocytes of peripheral blood.

The purpose of this study was cytometric evaluation of phagocytic and oxidative burst activity of neutrophils and monocytes in cats naturally infected with FeLV. To conduct the study, the peripheral blood was obtained from 33 cats naturally infected with FeLV. The control group consisted of 30 FeLV-, FIV-, clinically healthy cats.

Alpha-fetoprotein in canine multicentric lymphoma.

The concentrations of AFP were evaluated in the sera from groups of healthy dogs and of dogs with multicentric lymphoma, before and while receiving chemotherapy. The concentration of AFP was highest in the affected dogs, especially during the fifth stage of lymphoma. Chemotherapy caused a decrease in AFP serum concentration, during both the induction and the maintenance phases of treatment, when compared to the same animals before therapy.
