monocytes from patients with tuberculosis produced significantly higher activities of il-1 than did those from healthy tuberculin reactors when stimulated with lipopolysaccharide ( lps ) ( patients , 56.1 +/- 20.0 u/ml ; healthy control subjects , 7.3 +/- 1.7 u/ml ; p less than 0.05 ) or ppd ( patients , 28.1 +/- 7.2 u/ml ; healthy control subjects , 9.5 +/- 2.9 u/ml ; p less than 0.05 ) .
