Innovations in the agro-industrial sector are determined by development of biotechnologies from stage growing raw materials to their processing and storage. In compliance with phytosanitary requirements (including use radiation technologies) for grain, issues ensuring preservation dry composite mixtures storage conditions bitechnological techniques prolonging shelf life when adding phytosources...

Article history: Received 6 March 2008 Received in revised form 3 July 2008 Accepted 5 July 2008 The aim of the present trial was to evaluate the effect of repeated short-time applications of Echinacea purpurea juice as feed additive to initiate an immune response. In a trial with 70 white layers (LSL) two Echinacea juices as feed additives were tested for their influence on feed intake, perfor...

BACKGROUND: It is important to understand the efficacy of immunoregulatory materials, herbal remedies or probiotics, in different parts of immune system following vaccination with different tropism. OBJECTIVES: Aim of this study was to evaluate the effect of Echinacea purpurea and a probiotic (protexin) on systemic and mucosal immune response in turkey. METHODS: A total of 288 1-day-old male tu...

In order to assess the immunopathological effects of aqueous Echinacea purpurea extract (EPE) on mice experimentally challenged with Pasteurella multocida serotype A, forty female BALB/c mice were randomly divided into four groups. The groups included a control group (received sterile distilled water 2 times/week for 2 weeks, intraperitoneally and then 100 µl sterile saline intranasally), a PMA...

The effect of aqueous extract of Echinacea purpurea roots on the murine antibody response to Bothrops asper snake venom in vivo was studied. Three groups were used. Group #1, baseline control, was treated with snake venom plus PBS. Group #2 was treated with snake venom plus sodium alginate as adjuvant (routine method used at Instituto Clodomiro Picado), and group #3 or experimental group, was t...

Tephrosia purpurea is a copiously branched herbaceous perennial plant distributed throughout the tropics which is used in the treatment of bronchitis, diuretic, pimples, tonic, laxative, cough, and tumour. The present study is an attempt to explore the anthelmintic activity of aqueous and methanolic extract of leaves of plant Tephrosia purpurea . The various concentrations of aqueous and methan...

Because of the popularity of Echinacea as a dietary supplement, researchers have been actively investigating which Echinacea constituent or groups of constituents are necessary for immune-modulating bioactivities. Our prior studies indicate that alkylamides may play an important role in the inhibition of prostaglandin E2 (PGE(2)) production. High-performance liquid chromatography fractionation,...
