Este estudo foi concebido com o fito de avaliar os efeitos do azul de metileno sobre as respostas clínica, celular e bioquímica, na endotoxemia experimental em equinos. Os animais foram divididos em três grupos. LPS+AM recebeu LPS e foi tratado com 3mg/kg de azul de metileno 60 minutos após a indução da endotoxemia; LPS+NaCl também recebeu LPS e foi tratado com 3mg/kg de azul de metileno 255 minutos após a indução da endotoxemia, e NaCl+AM que recebeu NaCl e foi tratado com azul de metileno 60 minutos após a infusão do NaCl. Foram realizados exames clínicos e laboratoriais durante 12 horas em quatro momentos. Observou-se aumento de temperatura, leucopenia e aumento no fibrinogênio nos animais pré-tratados com LPS, a partir do momento 90minutos. Não foi possível afirmar se houve efeito benéfico do azul de metileno sobre a resposta dos equinos frente à endotoxemia experimental. / Endotoxemy is a severe disturb in Veterinary Clinics and one of the most important causes of deaths in equine. Recent papers report the efficiency of methylene blue in preventing the damage caused by nitric oxide. The aim of this work was to study the effects of methylene blue in clinic, cellular and biochemistry responses in experimental endotoxemy of horses. The animals were divided in three groups. The group LPS+AM received LPS and was treated with 3mg/Kg of methylene blue 60 minutes after the induction of endotoxemy; LPS+NaCl also received LPS and was treated with 3mg/Kg of methylene blue 255 minutes after the induction of endotoxemy and NaCl+AM that received NaCl and was treated with methylene blue 60 minutes after NaCl infusion. Clinical and laboratorial exams were done in four moments during 12 hours. There was an increase in temperature levels, leucopenia and increase in fibrinogen in the animals treated with LPS, beginning within 90 minutes. It was not possible to affirm if there was any benefit in the use of methylene blue in inflammatory response of horses with induced endotoxemy.
