13. The putative role of ovary removal and progesterone when considering the effect of formaldehyde exposure on lung inflammation induced by ovalbumin
OBJECTIVE: Formaldehyde exposure during the menstrual cycle is known to affect the course of allergic lung inflammation. Because our previous data demonstrated that formaldehyde combined with an ovariectomy reduced allergic lung inflammation, we investigated the putative role of ovary removal and progesterone treatment when considering the effect of formald

14. Expression of costimulatory molecules in antigen-activated peritoneal macrophages treated with either ovalbumin or palmitoyl-ova conjugates
One of the mechanisms by which adjuvants are believed to promote T-cell activation and prevent induction of oral tolerance is by up-regulating the expression of co-stimulatory molecules on antigen presenting cells. Mice treated orally with palmitoyl-ovalbumin conjugates become immunized, while those treated with native ovalbumin (Ova) become tolerant. Cells

15. Ethanol affects the absorption and tissue distribution of orally administered antigens in mice
The aim of this work was to evaluate the effects of ethanol on the adsorption and tissue distribution of orally administered antigens in mice. Results showed that ethanol reduced the level of anti-ovalbumin IgA antibodies in intestinal fluid for the mice treated orally with a palmitoyl-ovalbumin conjugate. Ethanol was administered intragastrically to mice at

16. On the relationship between the solubility of proteins and the osmotic second virial coefficient
A relationship between the osmotic second virial coefficient of proteins in aqueous salt solutions, the solubility of proteins in these solutions and the salt concentration is presented. The model developed considers that the solid-liquid equilibrium is established with neutral protein molecules and that the relationship between the protein solubility and th

17. Effect of oral administration of Propionibacterium acnes on growth performance, DTH response and anti-OVA titers in goat kids
Immunostimulants are susbstances that stimuli the response of effector cells to activate the immune response such as antigen uptake, cytokine release or antibody response. These substances can increase resistence to infection by different types of microorganisms, reducing dependence of antibiotics used in livestock animals. Recent reports have demonstrated t

18. Tratamento com inibidor da Rho quinase em cobais com inflamação pulmonar alérgica crônica: modulação da inflamação eosinofílica, da expressão de citocinas inflamatórias, da matriz extracelular e do estresse oxidativo no parênquima pulmonar / Treatment with Rho-kinase inhibitor in guinea pigs with chronic allergic inflammation: modulation of eosinophilic inflammation, expression of inflammatory cytokines, extracellular matrix and oxidative stress in lung tissue
RATIONALE: Previous studies with Rho-kinase inhibitors suggest a beneficial influence of these drugs in asthma. The relevance of distal lung tissue in functional asthmatic impairment has been intensely emphasized. There have not been any previous studies evaluating the effects of these inhibitors on the modulation of distal lung mechanics and histopathologic

19. Estudo da ativação eosinofílica e de matriz extracelular de tecido pulmonar periférico em cobaias com inflamação alérgica pulmonar: efeitos do tratamento com dexametasona e antagonista do receptor do cisteinil-leucotrieno D4
Aims: Compare the effects of montelukast or dexamethasone treatments on eosinophilic recruitment, eotaxin, RANTES, fibronectin, IGF-I and NF-B positive cells of distal lung parenchyma and also in airway walls of guinea pigs (GP) with chronic allergic inflammation. Methods: GP were inhaled with ovalbumin (OVA group-2x/week/4weeks). After 4th inhalation, GP we

20. Effect of lipoarabinomannan from Mycobacterium avium subsp avium in Freund’s incomplete adjuvant on the immune response of cattle
The aim of the present study was to determine whether lipoarabinomannan (LAM), in combination with Freund’s incomplete adjuvant (FIA), was able to improve cell-mediated and antibody-mediated immune responses against ovalbumin (OVA) in cattle. Twenty-three calves were assigned to four treatment groups, which were subcutaneously immunized with either OVA plu

21. Efeito da imunização materna com Ovalbumina na ativação de células dendríticas e geração de linfócitos T reguladores na prole de camundongos. / Effects of maternal immunization with Ovalbumin in activation of dendritic cells and generation of T regulatory lymphocytes in mice offspring.
A predisposição genética associada à predisposição dos neonatos em gerar uma resposta do tipo Th2 ao alérgeno pode favorecer o desenvolvimento de alergia no período neonatal. O presente projeto tem como proposta investigar os mecanismos regulatórios decorrentes da imunização com ovalbumina pré-concepção na resposta IgE da prole. A imunização

22. Pharmacological effects of the sesquiterpenic alcohol (-)-α-bisabolol in vascular and non-vascular smooth muscle preparations. / Efeitos farmacolÃgicos do Ãlcool sesquiterpÃnico (-)-α-bisabolol em preparaÃÃes isoladas de mÃsculo liso vasculares e nÃo-vasculares.
In this in vitro study the effects of the monocyclic sesquiterpene alcohol (-)-α-bisabolol on the contractile behavior of rat and mouse smooth muscle preparations were investigated. Under resting tonus, (-)-α-bisabolol relaxed duodenal smooth muscle preparations, whereas it showed biphasic effects in other smooth muscles, contracting endothelium-in

23. Modulação da artrite experimental induzida pela associação de colágeno tipo II e ovalbumina / Modulation of experimental arthritis induced by the association of ovalbumin and type II collagen
O camundongo BALB/c, linhagem geneticamente resistente à artrite induzida por colágeno (CIA), pode desenvolver um quadro similar ao de camundongos susceptíveis quando uma proteína não relacionada ao próprio, como a ovalbumina (OVA), é associada a colágeno tipo II (CII). Utilizando esse modelo, avaliamos se a tolerância oral a OVA poderia interferir

24. Avaliação do potencial erosivo do suco de laranja modificado pela adição de caseína e ovalbumina / Evaluation of the erosive potential of an orange juice modified by the addition of casein and ovalbumin [dissertation
The erosive potential of a modified orange juice by addition of casein, ovalbumin and its combination, on human enamel and root dentin was evaluated in this in vitro study. Two dietary proteins, 0.2 g/l casein (CAS), 2.0 g/l ovalbumin (OVA) and their combination (CAS + OVA) were added to a commercially available orange juice. The juice with no additives was
