Mushroom-derived preparations in the prevention of H2O2-induced oxidative damage to cellular DNA
(Teratogenesis Carcinogenesis and Mutagenesis, 2002-03-06) [Artigo]
Aqueous extracts of the sporophores of eight mushroom species were assessed for their ability to prevent H2O2-induced oxidative damage to cellular DNA using the single-cell gel electrophoresis (Comet) assay. The highest ...
Natural killer activity in a medium-term multi-organ bioassay for carcinogenesis
(Japanese Journal Of Cancer Research : Gann, 1999) [Artigo]
Natural killer (NK) cell activity was evaluated after the initiation and promotion steps in a medium-term multi-organ bioassay for carcinogenesis. NK cell activity was assessed in vitro by Cr51 release assay at the 4th and ...
Effects of fasting and intermittent fasting on rat hepatocarcinogenesis induced by diethylnitrosamine
(Teratogenesis Carcinogenesis and Mutagenesis, 2002-01-01) [Artigo]
The influences of fasting on DEN-initiation and of intermittent fasting (IF) on the rat liver chemical carcinogenesis process were evaluated in a 52-week long assay. Three groups of adult male Wistar rats were used: Groups ...

Immunohistochemical characterisation of probable intravascular haematopoiesis in the vasa rectae of the renal medulla in acute tubular necrosis
(Pathology Research and Practice, 1994-12-01) [Artigo]
Immunohistochemistry was applied to identify the nature of the nucleated cells that accumulate in the vasa rectae of the corticomedullary junction in acute tubular necrosis. In all 6 cases studied, there were intravascular ...
No mutations found in exons of TP53, H-RAS and K-RAS genes in liver of male Wistar rats submitted to a medium-term chemical carcinogenesis assay
(Jornal Brasileiro de Patologia e Medicina Laboratorial, 2002-07-01) [Artigo]
O teste padrão para identificar o potencial cancerígeno de compostos químicos é o estudo de longa duração em roedores, não realizado no Brasil. Nosso laboratório estabeleceu um teste alternativo de média duração (ensaio ...
Photodynamic therapy for the treatment of induced mammary tumor in rats
(Lasers in Medical Science, 2013-02-01) [Artigo]
The objective of this work was to evaluate photodynamic therapy (PDT) by using a hematoporphyrin derivative as a photosensitizer and light-emitting diodes (LEDs) as light source in induced mammary tumors of Sprague-Dawley ...
