Design: cross-sectional cohort<br />

Subjects: adult males occupationally<br />

exposed to Pb (n = 84), mean age 30 yr;<br />

reference subjects (n = 30), mean age 29 yr<br />

Outcome measures: serum IFN-( level,<br />

mitogen (PHA)-induced lymphocyte<br />

proliferation, NK cell cytotoxicity<br />

Analysis: comparison <strong>of</strong> outcome measures<br />

between Pb-exposed and reference groups,<br />

correlation<br />

Design: cross-sectional cohort<br />

Subjects: adult Pb (oxide) workers (n = 39),<br />

mean age 35.6 yr (9,2, SD); age-matched<br />

reference subjects (n = 19)<br />

Outcome measures: serum IgA, IgG;<br />

mitogen (PHA, Con-A)-induced lymphocyte<br />

proliferation<br />

Analysis: comparison <strong>of</strong> outcome measures<br />

between Pb workers and reference group<br />

Design: cross-sectional cohort<br />

Subjects: adult male occupationally Pb<br />

exposed (n = 10), age range 22–70; agematched<br />

reference subjects (n = 10)<br />

Outcome measures: mitogen (Con A, PHA)induced-lymphocyte<br />

proliferation and Tsuppressor<br />

cell proliferation; lymphocyte<br />

phenotype abundance<br />

Analysis: parametric comparison <strong>of</strong><br />

outcome means between Pb-exposed and<br />

reference groups<br />
