Antileishmanial Effect of Echinacea purpurea Root Extract Cultivated in Iran

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...

Factors Modifying Host Resistance to Viral Infection

The resistance of mice to encephalomyocarditis (EMC) virus was markedly decreased by prior exposure to whole body X-irradiation. In contrast to non-irradiated controls, the course of EMC virus infection in X-irradiated animals was characterized by (a) an enhanced mortality, (b) shortening of the incubation period, (c) higher levels of virus in the blood during the viremic phase and persistence ...
