Changes in pleural fluid composition after lung transplantation

Sequential changes in pleural fluid red cell and white cell counts (per mm³) and LDH concentration (IU/L) in six patients after lung transplantation. In addition to the progressive decline in LDH and cell counts, there were also reductions in the neutrophil proportions (89 down to 29 percent of total WBC) and total protein content (3.4 down to 2.1 g/dL) during this time period.
