Lymphocyte phenotypes

CD_2-/CD₁₉₊cells **(B lymphocytes)	1.9 ± 0.3
CD₃₊/CD₁₆₊CD₅₆₊**(cytotoxic lymphocytes)	2.8 ± 0.5
CD_3-/CD₁₆₊CD₅₆₊**(natural killer cells)	4 ± 0.6
CD₃₊cells ** (TLs)	74.2 ± 4.6

Values are means ± SEM (with ranges in parentheses). ^§The mean value of recovered BAL is 55.6% with a range of 41.6% to 80% *Values are expressed as percentages of total BAL cell count. ** Values are expressed as percentage of total lymphocytes.
