Nephrotoxicity is one of the most frequent effects observed after the use of medicine. Such situations have been tardily discovered because of existing methods to determine toxicity. The validation of sensitive, alternative methods for the early identification of toxic effects is as important as restrictions on the use of animals. In this light, the present study evaluated the effects of gentamicin on BGM and LLC-PK1 cells, using MTT and Neutral Red (NR). Although the LLC-PK1 cell line is used for toxicological studies, the BGM cell line is relatively new for this purpose. MTT (BGM: EC(50) = 6.29 mM; LLC-PK1: EC(50) = 8.01 mM) was found to be more sensitive than NR (EC(50) was greater than 10 mM for both cells). By using MTT, both cells demonstrated the involvement of mitochondria in a manner that was dose dependent, with an apoptotic process occurring at the concentrations of 1 and 3 mM and necrosis at concentrations above 4 mM. It could, therefore, be concluded that 1) BGM appears to be useful in the study of the mechanism of nephrotoxicity caused by gentamicin and 2) because of its sensitivity to MTT, in addition to its ease of manipulation, it is believed that the BGM cell line can also be used as an alternative method to evaluate nephrotoxicity.
Este artigo objetiva relatar experiência exitosa na implementação da Rede de Urgência e Emergência (UeE) com foco nos leitos de Unidade de Terapia Intensiva (UTI), na Macrorregião Norte, do Estado de Minas Gerais, no período de 2002 a 2010, nos hospitais públicos previamente selecionados, pertencentes as microrregiões pólos de Brasília de Minas, Janaúba, Pirapora, e Taiobeiras . O planejamento do trabalho desenvolvido nesse relato, na escolha dessas micros teve como indicadores de saúde escolhidos pela Coordenadoria de UTI da Secretaria de Estado de Minas Gerais (SES/MG): Índice de Desenvolvimento Humano (IDH), Disability Adjusted Life Years (DALY) ou Anos de Vida Perdidos Ajustados por Incapacidade (AVPI), Deficiência dos Hospitais, Localização Geográfica, Renda Per Capta, Tripla Carga de Doenças, Alto Índice de Mortalidade, e outros. Tendo como resultados a ampliação do parque de leitos de UTI no total de 40 leitos nesses municípios, onde foram criadas câmaras técnicas de trauma, cardiologia e AVC, diminuição da mortalidade, e núcleos de educação permanente implantados.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
