Amiodarone, a cardiac antiarrhythmic agent, has been associated with the development of interstitial pulmonary fibrosis in patients receiving prolonged therapy with the drug. To further assess the toxic effects of amiodarone on lung tissue, Syrian hamsters were given a single intratracheal insufflation of the agent and evaluated for histologic evidence of… (More)
In an observational study, the validity and reliability of magnetic resonance imaging (MRI) for the assessment of autologous chondrocyte transplantation (ACT) in the knee joint was determined. Two years after implantation, high-resolution MRI was used to analyze the repair tissue with nine pertinent variables. A complete filling of the defect was found in… (More)
Lysyl oxidase activity was measured in lung extracts of hamsters with elastase-induced emphysema 8 days after administration of the enzyme and again after 2, 3, and 4 wk. Levels of activity rose rapidly to 7 times the base values determined in the lungs of saline-injected control animals. In parallel with the increase in lysyl oxidase activity, the rate of… (More)
Incompetence of the uterine cervix is a syndrome of painless, progressive dilatation and effacement occurring between the sixteenth and twenty-fourth weeks of gestation that represents abnormal functioning. It may serve as a model to elucidate normal function. Because the incompetent cervix results in painless opening of this organ without uterine… (More)
Synthesis of crosslinked elastin was measured in cultures of pleural mesothelial cells. Results indicate that mesothelial cells are a rich source of crosslinked elastin and may therefore be useful for in vitro studies of this connective tissue component.
