. To determine whether functional atypical β-adrenoceptors (β3-adrenoceptors) are present in pulmonary vascular smooth muscle, we studied isolated canine pulmonary arterial rings under isometric conditions in vitro. Addition of β-adrenoceptor agonists produced a concentration-dependent relaxation of noradrenaline-precontracted tissues, a rank order potency being isoproterenol (1) > salbutamol...
. In prone anesthetized rabbits, we used Evans blue-dyed albumin (EBA) to study regional pleural filtration and FITC dextran to study regional pleural absorption. Evans blue was injected intravenously, and the animals were ventilated for 6 h at either of two levels of ventilation. Postmortem the right rib cage was frozen and thawed before study. EBA fluorescence emitted from the rib cage surface...
. Albumin diffusion measured in an isolated segment of rabbit lung interstitium with a radioactive tracer (125I-albumin) technique was independent of albumin concentration and similar to the free diffusion of albumin in water (Qiu et al, 1998. J Appl Physiol 85: 575–583). We studied the effect of hyaluronidase on the diffusion of albumin. Isolated rabbit lungs were inflated with silicon rubber by...

. It has been suggested that cytokeratin 19 is expressed in regenerated bronchoepithelial cells in patients with pulmonary fibrosis, and serum cytokeratin 19 fragment is elevated in patients with pulmonary fibrosis. We hypothesized that serum antibodies to cytokeratin 19 may be formed in patients with pulmonary fibrosis. To prove the existence of anti-cytokeratin 19 antibodies in patients' sera,...
. Fifty patients with adenocarcinoma of the lung were enrolled in this study, including 20 patients with recurrence and 30 patients without recurrence 1 year after surgery. Serial serum levels of cytokeratin fragment 19 (CYFRA 21-1) and carcinoembryonic antigen (CEA) were measured before the operation and 1 week, 1 month, 3 months, 6 months, 9 months, and 12 months after surgery for the early detection...

Abstract. To determine whether functional atypical -adrenoceptors (3-adrenoceptors) are present in pulmonary vascular smooth muscle, we studied isolated canine pulmonary arterial rings under isometric conditions in vitro. Addition of -adrenoceptor agonists produced a concentration-dependent relaxation of noradrenaline-precontracted tissues, a rank order potency being isoproterenol (1) salbutamol (0...
