Efeito do envelhecimento e do estresse crônico sobre a reação do tecido conjuntivo subcutâneo: estudo histológico em ratos
Physiological functions undergo a gradual retardation that begins around 25-30 years and extends to the death. Moreover, this change affects most severely the activities more complex and more intricate responses to tensions or stress. The purpose of this study was to evaluate histologically in aged...

| Resumo: | Physiological functions undergo a gradual retardation that begins around 25-30 years and extends to the death. Moreover, this change affects most severely the activities more complex and more intricate responses to tensions or stress. The purpose of this study was to evaluate histologically in aged rats the effect of chronic stress on the reaction of subcutaneous connective tissue. The purpose of this study was to evaluate histologically in aged rats the effect of chronic stress on the reaction of subcutaneous connective tissue. For this purpose, 60 rats were divided into four groups (GI (control), GII (stressed), GIII (elderly) and GIV (aged / stressed) received dorsal subcutaneous implants of polyethylene tubes containing saline solution. In groups of four animals were sacrificed at 7,14 and 28 days postoperatively. The results allowed to observe more intense inflammatory reaction and tissue organization later in the aged animals subjected to stress. |
