1. Evaluation of the immunomodulatory effect against splenocytes of Balb/c mice of biflorin obtained from Capraria biflora by a new isolation method
Abstract Biflorin (6,9-dimethyl-3-(4-methylpent-3-en-1-yl) benzo[de]chromene-7,8-dione) is a promising substance that has been increasingly studied in the past decades due to its diverse pharmacological properties (i.e. antitumor, antioxidant, antiinflamatory, antimicrobial activity etc.). Aiming the comprehension of its antitumoral activity we investigated

2. Immunostimulation and increase of intestinal lactic acid bacteria with dietary mannan-oligosaccharide in Nile tilapia juveniles
ABSTRACT In this experiment, the beneficial effects of mannan-oligosaccharide (MOS) on immunology and intestinal microbiology of Nile tilapia juveniles was demonstrated. Prior to this, three levels of MOS in Nile tilapia diets (1, 8, and 15 g.kg−1) were tested, and hematological parameters, serum lysozyme, and intestinal microbiology were analyzed. The fis

3. Immunotoxic effects of Pteridium aquilinum in natural killer cells from mice and the reversion of these effects by selenium / Efeitos imunotóxicos da Pteridium aquilinum em células natural killer de camundongos e a reversão destes efeitos com selênio
Os resultados obtidos no mestrado mostraram que a samambaia do campo (Pteridium aquilinum) reduz a citotoxicidade das células natural killer (NK) esplênicas e a resposta imune celular do tipo tardia (DTH) de camundongos. Entretanto, até aquele momento não era sabido qual a célula afetada pela planta causava a diminuição da DTH. Assim, o objetivo inici

4. Estudo do potencial anticÃncer de substÃncias obtidas do zoantÃdeo Protopalythoa variabilis Duerden, 1898 (CnidÃria, Anthozoa) encontrado no litoral Cearense / Study of anticancer potential of compounds obtainded from the zoanthid Protopalythoa variabilis duerden, 1898 (cnidaria, anthozoa) from the cearà coast.
O cÃncer à um dos principais problemas mundiais de saÃde e uma das causas mais importantes de morbidade e mortalidade em crianÃas e adultos. Apesar do sucesso no tratamento de diversos tipos de tumor, ainda nÃo se chegou ao fÃrmaco ideal e as terapias existentes nem sempre alcanÃam resultados satisfatÃrios alÃm de induzir muitos efeitos colaterais.

5. Mananoligossacarídeo e colistina na dieta de leitões desmamados
The objective of this trial was to evaluate the effects of prebiotic, antimicrobial, or association of both promoters in piglets diet upon performance, intestinal histomorfometry, and total IgA and IgG serum levels, in each treatment. The experiment was carried out in commercial pig farm, one-site production, using a hundred weaned castrated males, hybrid pi

6. Measurement of IL-10 serum levels in BALB/c mice treated with beta-1,3 polyglucose or sulfadiazine and acutely infected by Toxoplasma gondii
Acute infection by Toxoplasma gondii leads to suppression of cell-mediated immunity, facilitating chronic infection. One of the causes of immunosuppression is Interleukin-10 (IL-10) production. Glucan is used to stimulate phagocytosis. Our objective was to study IL-10 induction in male BALB/c mice with acute T. gondii BTU-2 strain infection, glucan immunosti

7. An alternative for antibiotic se in poultry: probiotics
Over the past 50 years, there has been increasing amounts of antibiotics used prophylactically and as growth promoters. Today, there is a consumer and governmental outcry to eliminate that practice from poultry and livestock production. Evidence has been accumulated to show that there is a link between risk of zoonotic disease and growth promoting antibiotic

8. Aspects of gastrointestinal immunology and nutrition in human immunodeficiency virus-1 infection in Brazil
Mucosal surfaces have a fundamental participation in many aspects of the human immunodeficiency virus (HIV) infection pathogenesis. In Brazilian HIV-1 infected subjects, loss of weight and appetite are among the most debilitating symptoms. In this review we describe a defined mucosal immunogen that has profound but transient effects on HIV viral load, and we

9. Brucella antigen preparations for in vitro lymphocyte immunostimulation assays in bovine brucellosis.
Three Brucella antigen preparations, Brucella abortus soluble antigen, B. abortus strain 45/20 enriched protein antigen, and B. melitensis enriched protein antigen, were compared in terms of their ability to induce specific in vitro lymphocyte immunostimulation responses. Lymphocytes were prepared from peripheral blood of cattle with different exposure exper

10. Stimulation of human monocytes by endotoxin-associated protein: inhibition of programmed cell death (apoptosis) and potential significance in adjuvanticity.
Mononuclear phagocytes are essential for adjuvant activity and polyclonal immunoglobulin synthesis induced by endotoxin-associated protein (EP) from Salmonella spp. To define the mechanisms of EP-mediated immunostimulation, we evaluated monocyte functions central to adjuvanticity following exposure to Salmonella typhimurium EP. In this study, we show that EP

11. Revisiting immunosurveillance and immunostimulation: Implications for cancer immunotherapy
Experimental and clinical experience demonstrates that the resolution of a pathogenic challenge depends not only on the presence or absence of an immune reaction, but also on the initiation of the proper type of immune reaction. The initiation of a non-protective type of immune reaction will not only result in a lack of protection, but may also exacerbate th

12. Effect of oral administration of lysozyme or digested bacterial cell walls on immunostimulation in guinea pigs.
The effect of oral administration of bacteriolytic enzymes and enzymatically digested bacterial cell walls on immunostimulation in guinea pigs was studied. Guinea pigs were given lysozyme or pronase or both orally for a period of 8 days, and on day 7 they were primed with hepatitis B surface antigen. Circulating antibody titers to the antigen in the enzyme-t
