Infarto do miocárdio experimental em ratos: Análise do modelo
(2009-10-01)
One of the most often used strategies to study the physiopathological alterations caused by coronary occlusion is the use of the experimental infarction model in rats. Among other factors, this is due to the similarities ...

(2013-05-01)
Studies have demonstrated that nutrient deficiency during pregnancy or in early postnatal life results in structural abnormalities in the offspring hippocampus and in cognitive impairment. In an attempt to analyze whether ...
Microwave-induced fast decalcification of rat bone for electron microscopic analysis: An ultrastructural and cytochemical study
(2007-12-01)
Bone decalcification is a time-consuming process. It takes weeks and preservation of the tissue structure depends on the quality and velocity of the demineralization process. In the present study, a decalcification methodology ...
Evaluations hematological and biochemical by the use of sodium diclofenac, meloxicam and firocoxib in rats
(2010-12-01)
This work has evaluated the hematological and biochemical profile by the use of sodium diclofenac, meloxicam and firocoxib in Wistar rats. The rats were distributed in groups: G1 (control), G2 (diclofenac sodium: 15 mg/kg), ...
