BACKGROUND: The immunostimulating effect of Aloe vera in mammals has been documented, but few works were done on effect of A. vera on fish health and immune responses. OBJECTIVES: In this study the effect of oral administration of A. vera on growth indices, hematological parameters and immune responses of rainbow trout were investigated. METHODS: One thousand five hundred rainbow trout fingerli...

Background: In recent years, immunonutrition has been introduced and proposed to have a positive modulatory effect on inflammatory immune responses gut function for surgical patients, especially patients undergoing gastrointestinal cancer resection. We conducted this parallel-group, randomized double-blind clinical controlled trial investigate the efficacy of perioperative enteral (EIN) immunol...

The host immunological pathways are re-organized to get a clear picture. There are four acute immune responses: TH1/TH2/TH22/THαβ which are corresponding to four chronic immune responses: TH1Like/TH9/TH17/TH3. Then, the four branches of immune reactions can link to four types of hypersensitivities or allergies. THfh is the stimulatory pathway to initiate adaptive acute immunity. Another inhibit...

conclusions the results showed that the extracted omvs were conformationally stable, and there were no pyrogenic determinants in omv. also the results showed that the omv elicited high level of specific antibodies against n. meningitidis serogroup a. these results indicate that the omv obtained here, can be used as a meningococcal vaccine after further investigation. materials and methods omvs ...

the aim of this sutdy is to prepare histocompatability y(hy) antibody in female mouse at the first phase (current study), and to separate mouse embryos with regard to their sex, to be able to obtain offsprings of disired sex, by means of hy antibody, at the second phase. totally 421 balb/c inbred mice were used. antibodies were produced in females by intraperitonial injections of spleen and tes...
