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. The control group consisted of 80 dogs of various breeds. All the animals were clinically healthy. A full hematological analysis was performed. The mean platelet value in all dog breeds without the Polish ogar dogs was 344.4 ± 6.85, while the mean number of platelets in the Polish ogar dogs amounted to 167 ± 11.6 G/l. The limited genetic material used to rebuild the Polish ogar breed after its drastic decline during the Second World War could be the reason for various, including hematological, abnormalities that with time became a normal characteristic traits for this breed.
This aim of the study was to determine the activity of ADA serum and isoenzyme in feline retroviral infections. The study involved 6 FeLV seropositive, 4 FIV seropositive and 10 healthy seronegative cats aged between 1-8 years. Haematological, serum enzyme acivity (AST; ALT; ALP; GGT) as well as ADA serum and isoenzyme activity were determined in all the cats. Haematological parameters were within the normal range except for the platelet count in FIV seropositive cats (p<0.05). Serum enzyme activity was unchanged except for the AST concentration in FeLV and FIV seropositive cats compared to the healthy subjects. ADA serum and ADA1 concentrations were lower in the seropositive group than in the seronegative group. However, the decrease in ADA serum and ADA1 concentrations in FIV seropositive cats (p<0.01) was more significant than that of FeLV seropositive cats (p<0.05). In conclusion, decreased ADA and ADA1 activity in feline retrovirus infections may be significant.
The changes in some blood biochemical parameters were studied in the freshwater fish N. notopterus under saline exposure for a longer period of 30 days. The blood biochemical parameters are glucose, protein, triglycerides and cholesterol. All these parameters exhibited increased level except of blood glucose which remained unchanged as observed after the termination of saline exposure. Thus it indicates that although fish survives and able to tolerate extreme saline condition as there was no mortality during the exposure period. The increase of blood biochemical parameters can be considered as a kind of saline stress response particularly on lipid derivatives.
Целью соответствующих исследований была оценка снабжения организма овец отдельными биоэлементами на основании анализа шерсти. Материал для исследований отбирали трехкратно: в феврале, июне и сентябре. В шерсти определяли содержание золы, а также Na , К, Р, Са, Mg, Fe, Zn, Cu, Mn, Cd и Li. Проведенные исследования показали, что период содержания (зимнего, весеннего и летнего) оказывал статистически существенное влияние на содержание в организме многих макро- и микроэлементов.
Krew 15 uczestników badania WWF Polska analizowano pod względem zawartości związków chloroorganicznych (insektycydy, polichlorowane bifenyle), ftalanów oraz perfluorowanych związków alifatycznych w trzech laboratoriach zagranicznych. Spośród 39 badanych pojedynczych związków chemicznych, u każdej z osób wykryto od 18 do 22 substancji. Uzyskane wyniki wskazują, że środowisko otaczające każdego człowieka jest źródłem narażenia na wiele substancji chemicznych, z których część już dawno wycofano z produkcji i stosowania. Badane zanieczyszczenia mogą być odpowiedzialne za zwiększanie ryzyka występowania niektórych tzw. chorób cywilizacyjnych.
