Disturbance of the antioxidative-oxidative balance is a predisposing factor in the development of a variety of diseases. Microelements, including zinc and copper, are components of active enzyme regions participating in anti-oxidative systems. Patients with malabsorption syndrome may suffer from diseases related to the chronic deficiency of micro- and macroelements and vitamins, but also experience health problems due to an impaired antioxidative plasma defence, i.e. illnesses caused by oxidative stress. The aim of the study was to assess zinc and copper concentrations as well as the total antioxidant capacity of blood plasma in 33 patients hospitalized in the Department of Internal Medicine, Metabolic Diseases and Dietetics, presenting symptoms of intestinal malabsorption such as weight loss, abdominal pain and diarrhoea. Blood donors made up the control group. Statistically significantly lower concentrations of zinc and copper were found in the study group as compared to the control group for women and men together as well as for women and for men separately (p < 0.05). A significantly lower FRAP (Ferric Reducing Ability of Plasma) value as a measure of blood plasma the total antioxidative capacity was found in the study group of men in comparison with men from the control group (p < 0.05). Patients showed deficiencies of the two microelements despite normal values of BMI (Body Mass Index) and laboratory parameters such as haemoglobin, protein, albumin and iron concentrations. Regardless of the nutritional state assessment, patients with malabsorption syndrome should receive adequate supplementation of vitamins and microelements.

Doświadczenie przeprowadzono na 114 prosiętach różnej płci, podzielonych na grupę kontrolną, którą stanowiło 30 zdrowych zwierząt i doświadczalną obejmującą 84 prosięta z nieżytem przewodu pokarmowego. W badaniach biochemicznych uwzględniono aktywność α-amylazy w surowicy krwi i w moczu oraz lipazy w surowicy krwi. Ponadto oznaczano poziom witaminy A w surowicy, kreatyninę w moczu i surowicy. W kale oznaczano zawartość tłuszczów oraz jego pH. W wyniku przeprowadzonych badań należy stwierdzić, że występujące w przebiegu nieżytu przewodu pokarmowego zaburzenia metaboliczne mogą prowadzić do upośledzenia zewnątrzwydzielniczej sekrecji trzustki. Niedoczynność trzustki w zakresie syntezy amylazy i lipazy powoduje zaburzenia trawienia i występowanie na tym tle zespołu upośledzonego wchłaniania.

Исследования проведено на 114 поросятах разного пола, разделенных на две группы: первая — контрольная, в которой было 30 здоровых поросят, и вторая - опытная, охватывающая 84 животных с катаром пищеварительного тракта. В ходе биохимических исследований определялась активность а-амилазы в сыворотке и моче, а также активность липазы в сыворотке. Кроме того, определено уровень витамина А в сыворотке и креатинина в моче и сыроватке, а в кале — pH и содержание жиров. В результате проведенных исследований констатировано, что метаболические расстройства, наблюдающиеся при катаре пищеварительного тракта, могут привести к ослаблению эгзосекреторной деятельности поджелудочной железы. Гипофункция поджелудочной железы, проявляющаяся в понижении синтеза амилазы и липазы, вызывает расстройство пищеварения и связанный с этим синдром ослабленного всасывания.

The study was carried out on 114 piglets divided into control group which consisted of 30 healthy piglets and experimental group consisting of 84 diarrhoea piglets. Biochemical examinations including activity of α-amylase in serum and urine and activity of lipase in serum were done. There were also determined: the level of vit. A in serum, creatinine in serum and urine. Content of fats and pH of faeces were estimated, too. It was found that metabolic disorders in diarrhoea piglets is probably the reason of the occurence of the exocrine pancreatic hypofunction. Pancreatic hypofunction in amylase and lipase synthesis causes dyspepsia and malabsorption syndrome.

This work aims to identify 6 virus field isolates, serologically determined as reoviruses. The type of cytopathic effect in cell cultures, physico-chemical properties and antigenic relationship were examined. The strains examined multiplied in CEF and CEK cultures, produced cytopathic effects and plaques, contained RNA in their genome, had no lipid envelope, were stable in an acid environment and belonged to the same serotype but two different subtypes.
