Abstract

1 Successful use of agar-filled precision-cut rat lung slices in dynamic organ culture prompted the use of this technology with human lung. 2 The larger tissue mass of a human lung required that the trachea be cannulated with a balloon catheter and subsequently inflated with 4 liters of warm agar/medium mixture and then cooled before being precision-cut into 500 μm thick slices. 3 To characterize the human lung slices, viability and the effects of acrolein and nitrofurantoin were assessed over a period of 24 h using protein synthesis and nonprotein sulfhydryl content. 4 Control human lung slices synthesized protein at a linear rate and maintained a stable nonprotein sulfhydryl content for 24 h. 5 Slices incubated with acrolein exhibited no significant decrease in protein synthesis or nonprotein sulfhydryl levels until 24 h. 6 Incubation with nitrofurantoin exhibited a definite time- and dose-dependent inhibition of protein synthesis, and depletion of the cellular thiol pool. 7 These results indicate that this human lung tissue slice system may be used as an in vitro model to identify and screen pneumotoxicants.
