To analyze the action of strontium ranelate (SR) and melatonin in isolation or in association in knees, liver and kidneys of rats Wistar with induced osteoarthritis (OA). Methods: Thirty male rats were induced to OA through an anterior cruciate ligament transection (ACLT), and treated with melatonin and SR in isolation or in association. Morphological, histopathological, histochemical and morphometric analysis were realized of the structure of the articular capsule, as well as histopathological analysis of liver and kidneys from the animals. Results: The experimental model was successful. The association of the drugs presented chondroprotective pharmacodynamics. However, more successful results were identified from analysis of animals in which received melatonin in isolation, regarding biochemical parameters of glutamic oxalacetic transaminase. The prepared slide samples of liver and kidneys from groups submitted to the isolated use of SR and melatonin or the association of these drugs presented no differences, when compared to the control group. Discussion: The administration of the drugs presented chondroprotective effect and prevented from the aggravation of articulate damages, and was not capable of modifying the histology of liver or kidneys. This finding suggests a safe association for the treatment of OA, however it requires further investigation in order to expand therapeutic perspectives regarding improvements of the quality of life of individuals in our society.
Introdução: O paciente destinado a transplante cardíaco (TC) é portador de cardiopatia em estágio terminal, com fração de ejeção inferior a 20%. A reabilitação cardiopulmonar (RCP) consiste na integração de intervenções para assegurar melhoria nas condições físicas, psicológicas e sociais do paciente com doença cardiovascular e pulmonar. Objetivo: Revisar a literatura sobre os programas de RCP aplicados aos pacientes submetidos ao TC, comparando os efeitos dos programas sobre parâmetros hemodinâmicos e capacidade funcional. Material e métodos: A revisão de literatura foi desenvolvida mediante pesquisa bibliográfica das publicações nas bases de dados Pubmed, Lilacs, Medline e Scielo, no período de 1999 a 2010. Resultados: A RCP atinge grau de recomendação A e nível de evidência 1 nos pacientes com indicação para TC. Programas com duração de 8 a 12 meses podem aumentar em até 50% a capacidade funcional de pacientes submetidos ao TC. Estudos indicam que pacientes submetidos a programas de RCP que contemplam aquecimento, exercícios aeróbicos e relaxamento apresentam diminuição da PA e FC de repouso e aumento do VO2max. Conclusão: A prescrição de exercícios físicos para indivíduos submetidos à TC é de fundamental importância para a reabilitação cardiopulmonar, contribuindo para a melhoria da qualidade e expectativa de vida do transplantado.Palavras-chave: transplante cardíaco, Fisioterapia, reabilitação cardiopulmonar, exercício físico.
