RESUMO A transfusão de concentrado de plaquetas é prática comum para prevenção de sangramento espontâneo ou decorrente de procedimentos invasivos; sabe-se que a transfusão de componentes alogênicos do sangue se associa a aumento da mortalidade e piora do desfecho clínico. A força do coágulo é...

Toxicity of synthetic flavorings, nature identical and artificial, to hematopoietic tissue cells of rodents

Braz. j. biol; 78 (2), 2018
Abstract The goal of this study was to analyze cytotoxicity, genotoxicity and mutagenicity to bone marrow cells of mice of nature identical synthetic flavorings, passion fruit and strawberry, and artificial synthetic flavorings, vanilla, chocolate, tutti-frutti and cookie, at doses 0.5; 1.0; 2.0; 5.0 and...

Reduction of doxorubicin-induced genotoxicity by Handroanthus impetiginosus in mouse bone marrow revealed by micronucleus assay

Braz. j. biol; 78 (1), 2018
Abstract Handroanthus impetiginosus has long been used in traditional medicine and various studies have determined the presence of bioactive chemical compounds and potential phytotherapeutics. In this study, the genotoxicity of the lyophilized tincture of H. impetiginosus bark (THI) was evaluated in mous...

Bone marrow cell migration to the heart in a chimeric mouse model of acute chagasic disease

Mem. Inst. Oswaldo Cruz; 112 (8), 2017
BACKGROUND Chagas disease is a public health problem caused by infection with the protozoan Trypanosoma cruzi. There is currently no effective therapy for Chagas disease. Although there is some evidence for the beneficial effect of bone marrow-derived cells in chagasic disease, the mechanisms underlying...

Antigenotoxicity protection of Carapa guianensis oil against mitomycin C and cyclophosphamide in mouse bone marrow

An. acad. bras. ciênc; 89 (3,supl), 2017
ABSTRACT The aim of this study was to evaluate the possible protective of C. guianensis oil against MMC and CP, which are direct- and indirect-acting chemical mutagens, using the micronucleus test. Three experiments were performed. First the C. guianensis oil was co-administered to mice at doses of 250, ...

Estudo comparativo da diferenciação osteogênica das células tronco mesenquimais da medula óssea e do tecido adiposo de cães adultos

Pesqui. vet. bras; 36 (supl.1), 2016
O objetivo deste estudo foi comparar o potencial osteogênico das células tronco mesenquimais extraídas da medula óssea (CTM-MO) com as do tecido adiposo (CTM-AD) de cães adultos. As células foram caracterizadas fenotipicamente quanto à expressão de CD29, CD90, CD34 e CD45 e submetidas à diferenc...

Efectos in vivo del ranelato de estroncio sobre células progenitoras de médula ósea de ratas diabéticas
In vivo effects of strontium ranelate on bone marrow progenitor cells of diabetic rats

Actual. osteol; 12 (2), 2016
La diabetes mellitus (DM) crónica se asocia con reducción en el contenido mineral óseo (osteopenia y osteoporosis). El objetivo de este trabajo fue evaluar la acción del ranelato de estroncio (RaSr) administrado por vía oral a animales control y diabéticos, sobre el potencial osteogénico de célul...

Relationship between hypertension and periapical lesion: an in vitro and in vivo study

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to compare potential aspects of periapical lesion formation in hypertensive and normotensive conditions using hypertensive (BPH/2J) and wild-type control (BPN/3J) mice. The mandibular first molars of both strains had their dental pulp exposed. At day 21 the mice were eu...

Evaluation of the genotoxicity and mutagenicity of Ca3SiO5-based cement

Braz. oral res. (Online); 30 (1), 2016
Abstract Ca3SiO5 is new cement based on the composition of Portland that has been developed to have superior physicochemical and biological properties. In a clinical evaluation, the cement did not appear to have cytotoxic properties and allowed for the proliferation of pulp cells and gingival fibroblasts...
