25. Postmortem assessment of chronic airways obstruction by tantalum bronchography.
Tantalum bronchography was performed on 22 left lungs obtained at necropsy. Seven were from patients dying in cor pulmonale as a result of chronic airways obstruction and 15 were from unselected necropsies. Of the latter group, nine had no evidence of respiratory disease and six had pathological changes of emphysema and bronchial mucous gland enlargement whe

26. A quantitative neurohistological study of the long term effects in the rat brain of stimulation in infancy.
Infant rats were either handled daily during the first 10 days of life or left undisturbed. Brains were examined, using quantitative histological methods, at 22 days postnatum and at 6 months postnatum. At 22 days the handled animals showed a deficit in glial cells in both the anterior limb of the anterior commissure and in the indusium griseum. The deficit

27. Role of ventriculovascular coupling in cardiac response to increased contractility in closed-chest dogs.
While both dobutamine and pacing tachycardia augment left ventricular (LV) contractility, whether overall cardiovascular response to these stimuli is comparable is not known. To address this question we studied seven dogs previously instrumented with three LV diameter gauges and LV pressure manometers. After ganglionic blockade and sedation, caval occlusions

28. Sites and Mechanisms of Localization of Technetium-99m Phosphorus Radiopharmaceuticals in Acute Myocardial Infarcts and other Tissues
This study was performed to elucidate the localization at the cellular level of technetium-99m phosphorus (99mTc-P) radiopharmaceuticals in acute myocardial infarcts and the mechanisms responsible for 99mTc-P uptake in acute myocardial infarcts and other tissues. In 20 dogs with proximal left anterior descending coronary arterial ligation for 1-3 days, eleva
