While the importance of biochemical processes in plant adaptive responses is widely accepted, only a limited number studies have addressed cell-type specific and enzymatic activities E. purpurea under salt stress conditions. So, various antioxidant activities, H+ transport activity, non-invasive ion flux mechanisms root apex mature zones grown at different NO3-/NH4+ ratios (90:10, 80:20, 70:30)...

BACKGROUND Echinacea purpurea stimulates the immune response and is promoted to reduce symptom severity and the duration of upper respiratory tract infections. We sought to determine the efficacy of a standardized preparation of E purpurea in reducing symptom severity and duration of the common cold. METHODS A randomized, double-blind, placebo-controlled design was used. Patients received eit...

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...

Due to the limited availability of effective pharmaceutical products and serious side effects of the available therapy for leishmaniasis, search for useful medicinal plants is necessary. Previous studies reported preventative effect of Echinacea against Leishmania infections through immunologic stimulation. Here we tested concentrated ethanolic extract of the root of Echinacea purpurea prepared...

Nowadays green synthesis of metal nanoparticles is a developing area of research. In this study, titanium dioxide nanoparticles were biosynthesized using an aqueous solution of Echinacea purpurea herba extract as a bioreductant. This is novel and interesting method for synthesis of TiO2 nanoparticles. The prepared titanium dioxide nanoparticles were characterized using ultraviolet–visible spect...

newcastle disease is one of the most important causes of economic losses in the poultry production and can be resulted in high mortality. antibody detection is also an important tool for assessment of the immunity against the disease. in the present study a trial was conducted to evaluate the effect of an immune stimulator (echinacea purpurea) on antibody production against newcastle disease va...
