PURPOSE The aim of this study was to evaluate a natural history of congenital intestinal atresia (IA) in the chick embryo and to assess the type and nature of changes in the intestine at various developmental stages. METHODS Chick embryos underwent operative induction of IA on the 12th day of incubation. The procedure consisted of electrocoagulation of(More)
Experimental Mg deficiency leads to alterations in the immune response. Reduction of thymus weight and histological changes were previously observed in Mg-deficient rats after several weeks on a deficient diet, suggesting that functions of this immune organ may be affected by Mg deficiency. More recently, changes in the immune system during early Mg(More)
Experimental evidence from previous studies supports the conclusion that orally administered lactoferrin (LF) restores the immune response in mice treated with a sublethal dose of cyclophosphamide (CP). The aim of this study was to elucidate potential benefit of LF in mice undergoing chemotherapy with busulfan (BU) and CP, followed by intravenous (i.v.)(More)
The objective of the experiment was to study the effect of osteotomy technique on the course of bone regeneration in distraction osteogenesis in sheep. Thirty five merino sheep were divided into 5 groups of 7 sheep each, depending on the osteotomy technique: subcutaneous corticotomy, open corticotomy, Cattaneo corticotomy, open osteotomy and osteoclasia.(More)
The implementation of new methods of oseoporotic therapy requires tests on an animal model. One of the best is the sheep, whose numerous advantages over other models are described in the literature. The aim of this study was induction of osteoporosis using steroids and ovariorectomy methods in sheep and description of the change in parameters with regard to(More)
The importance of Mg for the immune function is well recognized; however, there is no information available about the effect of Mg intake on the modulation of local immune response in the intestine. Thus, in the present study the hypothesis that short periods of Mg deprivation can affect intestinal mucosa and local immune response was tested. For this(More)
Bronchial asthma is a chronic condition with an inflammatory background--allergic inflammation. In recent years several observations have been published documenting activity of low molecular weight heparin (LMWH) in chronic inflammatory diseases of respiratory tract. This study was set up to evaluate the effect of nebulized LMWH on spirometric parameters(More)
The chemical composition of spray dried porcine blood by-products is characterised by wide variation in crude protein contents. In spray dried porcine blood plasma (SDBP) it varied between 670-780 g/kg, in spray dried blood cells (SDBC) between 830-930 g/kg, and in bone protein hydrolysate (BPH) in a range of 740-780 g/kg. Compared with fish meal, these(More)
Spray-dried porcine blood plasma (SDBP) or blood cells (SDBC) at amounts of 20 or 40 g/kg were included to the feed mixtures that were given to young chickens within 1-28 (Exp. 1) or 1-30 (Exp. 2) days post-hatch. In comparison with the group fed mixtures containing plant components, chickens fed mixtures supplemented with 40 g/kg of SDBP significantly (p <(More)
Dietary magnesium deficiency in rodents, and especially in rats, causes inflammation and leads to alterations in the immune response. One of the characteristics of magnesium deficiency in the rat is a marked enlargement of the spleen. Considering the importance of the spleen for the immune response, in this study we have evaluated histological, cytological(More)
