1. Maintenance of subcutaneous cavities with CO2.
Match Strength: 9.018
Since mechanical retractors in endoscopic plastic surgery cause certain drawbacks, we developed a model in dogs, which, by insufflating CO2 into a subcutaneous cavity, we were able to maintain. We evaluated the magnitude of subcutaneous emphysema and absorption of CO2 by insufflating different pressures and the efficacy of external pressure on the skin with the purpose of limiting the subcutaneous emphysema. Sixteen dogs were divided in 3 groups, A, B, and C. We controlled the pulmonary function by using a volume-cycle ventilator. In all groups, we maintained a subcutaneous cavity by ... Read More »

2. Morphogenesis of rat experimental pulmonary emphysema induced by intratracheally administered papain: changes in elastic fibres.
Match Strength: 7.474
The ultrastructural changes of elastic fibres in emphysematous lungs have been studied in men, but few works exist on this topic in experimental emphysematous animals. In this paper, the morphogenesis of emphysema and alterations of the elastic fibres produced by the instillation of papain are described by light and electron microscopy. Wistar rats were instilled through the trachea with papain at a rate of 3 mg/100 g animal weight. The animals were sacrificed 12 h, 3 days, 10 days and 60 days after enzyme instillation. The "Mean Linear Intercept" (MLI), the "Number of fenestrations ... Read More »

3. Lung tissue engineering technique with adipose stromal cells improves surgical outcome for pulmonary emphysema.
Match Strength: 6.902
RATIONALE AND OBJECTIVES: Hepatocyte growth factor (HGF) is a potent regenerative factor generated after a lung injury, and HGF supplementation after surgical reduction has been shown to enhance compensatory growth in remnant lungs and improve pathophysiologic conditions in a rat model of emphysema. Adipose tissue-derived stromal cells (ASCs) produce a large amount of angiogenic factors, including HGF. After lung volume reduction surgery (LVRS), we treated rats by implanting HGF-secreting ASCs with a scaffold onto the remnant lung tissue to determine the usefulness of this technique for ...

4. Hepatectomy for colorectal liver metastases with macroscopic intrabiliary tumor growth.
Match Strength: 4.898
OBJECTIVES: We set out to clarify the clinicopathologic characteristics of colorectal liver metastases with macroscopic intrabiliary tumor growth and to determine optimal surgical management. METHODS: Over 15 years, 6 of 103 patients undergoing hepatectomy for colorectal liver metastases had macroscopic intrabiliary tumor growth and were analyzed retrospectively. RESULTS: We performed 11 operations for the 6 patients, consisting of 10 hepatectomies (including 1 hepatopancreatoduodenectomy) and 1 pancreatoduodenectomy. Three patients survived more than 5 years: 1 died of pulmonary emphysema ... Read More »

5. What we owe to alpha(1)-antitrypsin and to Carl-Bertil Laurell.
Match Strength: 4.317
The archetypal status of alpha(1)-antitrypsin in biology and medicine grew from the finding, thirty years ago, by Carl-Bertil Laurell, of the association of its deficiency with emphysema. In biology, alpha(1)-antitrypsin now provides the model for both the structure and the remarkable mechanism of the serpin protease inhibitors that control the key proteolytic pathways of the body. In medicine, the plasma deficiency of alpha(1)-antitrypsin has drawn attention to protease-antiprotease imbalance as a contributory cause of chronic obstructive pulmonary disease. But even more significantly, the ... Read More »
