Expression of IL-8 and TNF-α mRNAs during tuberculous pleurisy. Expression of IL-8 (A) and TNF-α (B) mRNAs was quantified in pleural fluid cells obtained from guinea pigs with tuberculous pleurisy euthanized on days 1 to 9. Fold induction was calculated as described in the legend to Fig. 3. Data and error bars represent the mean of three or four animals ± the standard error of the mean. An asterisk indicates a significant increase in mRNA expression compared with that on days 6, 7, and 9.
