Abstract
1. [131I]albumin transport from alveolus to perfusion fluid was evaluated in an isolated dog lung lobe preparation perfused at constant pressure with homologous plasma. The alveoli were filled with a 1:1 mixture of Ringer—Tyrode solution and plasma.
2. For twenty-three lung lobes, an average control permeability coefficient of the alveolocapillary membrane for albumin was found to be 1·9 × 10-9 cm/sec with a range of (0·3-5·5) × 10-9 cm/sec.
3. Alloxan in concentrations of 0·22-2·50 mg/ml. perfusate was observed to increase the alveolocapillary membrane permeability to [131I]albumin with a positive correlation between dose and effect. The larger doses of alloxan increased the permeability by a factor of ten or more.
4. Glutathione (GSH), administered intravascularly 2 min before alloxan in an 8:1 molar ratio of GSH:alloxan, delayed the onset of the permeability increase due to alloxan by 40-60 min but did not influence the maximum increase in permeability.
5. Histamine administered intravascularly in concentrations from 0·02 to 0·50 μg/ml. perfusate had no significant effect on the alveolocapillary membrane permeability to [131I]albumin.
