Quantification of Art v 1 and Act c 1 being major allergens of mugwort pollen and kiwi fruit extracts in mass-units by ion-exchange HPLC-UV method
(Elsevier Science Bv, Amsterdam, 2007)
A simple ion-exchange HPLC-UV method was developed for determination of major allergens from mugwort pollen and kiwi fruit extracts in mass-units. The separation of Art v 1 and Act c 1 from other components in the extracts ...
The influence of stress and methionine-enkephalin on macrophage functions in two inbred rat strains
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The aim of our current study was to investigate the effect of acute exposure to electric tail shock stress (ES) and to a stress witnessing procedure (SW), as models for physical and psychological stress paradigms, respectively, ...
Exposure to acute physical and psychological stress alters the response of rat macrophages to corticosterone, neuropeptide Y and beta-endorphin
(Taylor & Francis Ltd, Abingdon, 2007)
The objective of the present study was to investigate the effect of acute exposure to electric tail shock stress (ES) and a stress witnessing procedure ( SW), as models for physical and psychological stress paradigms, ...
Reactive oxygen species (ROS), but not nitric oxide (NO), contribute to strain differences in the susceptibility to experimental arthritis in rats
(Elsevier Gmbh, Munich, 2007)
There is extensive evidence for the critical role of reactive oxygen species (ROS) and nitric oxide (NO) produced by phagocytes in development of inflammatory processes and pathogenesis of numerous diseases, including ...
Strain differences in peritoneal macrophage activity and susceptibility to experimental allergic encephalomyelitis induction in rats
(Springer Basel Ag, Basel, 2007)
The objective of the present study was to investigate the relevance of peripheral macrophage activity for the susceptibility to the induction of experimental allergic encephalomyelitis (EAE). Rats of EAE-susceptible Dark ...
Neonatal castration affects intrathymic kinetics of T-cell differentiation and the spleen T-cell level
(Bioscientifica Ltd, Bristol, 2007)
To test putative interdependence in the ontogenesis of the hypothalamic-pituitary-gonadal and thymic-lymphatic axes, thymocyte differentiation and maturation was examined in neonatally castrated (Cx) adult rats. In the ...
Early postnatal castration affects thymic and thymocyte noradrenaline levels and beta-adrenoceptor-mediated influence on the thymopoiesis in adult rats
(Elsevier, Amsterdam, 2007)
The interactions among the nervous, endocrine and immune system were studied by examining: i) thymic and thymocyte catecholamine levels in adult rats castrated (Cx) at postnatal day 3 and ii) effects of 14-day-long propranolol ...
Beta-adrenoceptor blockade ameliorates the clinical course of experimental allergic encephalomyelitis and diminishes its aggravation in adrenalectomized rats
(Elsevier Science Bv, Amsterdam, 2007)
As glucocorticoids influence both catecholamine synthesis and adrenoceptor expression by immune cells, the current study was undertaken to distinguish their direct effects on the development of experimental allergic ...
Long-term beta-adrenergic receptor blockade increases levels of the most mature thymocyte subsets in aged rats
(Elsevier, Amsterdam, 2007)
Age-related increase in the density of thymic noradrenergic fibres and noradrenaline (NA) concentration is proposed to be associated with thymic involution and altered thymopoiesis. To test this hypothesis thymocyte ...
Peripubertal orchidectomy transitorily affects age-associated thymic involution in rats
(Assoc Bras Divulg Cientifica, Sao Paulo, 2007)
The role of gonadal hormones in induction and, particularly, maintenance/ progression of rat thymic involution, which normally starts around puberty, was reassessed by examining the effects of peripubertal orchidectomy on ...
