| مستخلص: |
Cells isolated from rat lung by protease digestion were found to catalyze the reduced glutathione (GSH) conjugation of 1-chloro-2,4-dinitrobenzene. The rate of conjugation was stimulated severalfold in the presence of GSH, indicating uptake and utilization of extracellular GSH by the lung cells. The stimulation was dependent on the GSH concentration and not due to a spontaneous nonenzymatic reaction or to extracellular GSH-transferase activity. Conjugation of 1-chloro-2,4-dinitrobenzene was also measured using isolated perfused rat lung. The conjugation, which was linear for a longer time than with the isolated cells, was also stimulated in the presence of GSH in the perfusion medium. The results indicate the ability of rat lung to utilize extracellular GSH. [ABSTRACT FROM AUTHOR] |
