(Centro de Estudos de Venenos e Animais Peçonhentos, 2005-03)
The direct effect of ethanolic extract of propolis on guinea pig lung cell suspension containing mast cells, as well as its influence on the histamine release induced by antigen (ovoalbumin 10 mug/ml) and ionophore A 23187 ...
Regulatory cells induced by acute toxoplasmosis prevent the development of allergic lung inflammation
(Elsevier Gmbh, 2014-12)
The increased prevalence of allergies in developed countries has been attributed to a reduction of some infections. Supporting epidemiological studies, we previously showed that both acute and chronic Toxoplasma gondii ...
