FIG. 1.

Accumulation of fluid and cells in pleural exudates of guinea pigs with tuberculous pleurisy. Fluid accumulation (A), cell accumulation (B), and cell concentration (C) were measured in control pleuritic guinea pigs and guinea pigs receiving experimental injections of anti-TGF-β1. Cells were stained with trypan blue and counted with a hemocytometer. The bars and error bars indicate averages and standard errors of the means for three of four animals. An asterisk indicates that there is significant difference between the number of cells or fluid volume and the number of cells or fluid volume in control guinea pigs.
