Reactive oxygen intermediates production in AA and BB subjects

Samples	Mean fluorescence channel for indicated genotypea		Pb
	AA	BB
Controlc	1.10 ± 0.20	1.03 ± 0.15	NS
Noninfected	6.93 ± 1.20	17.77 ± 2.36	0.0209
Infected	28.67 ± 4.04	83.67 ± 6.66	0.0024

^aValues are the means ± standard deviations of 10 AA and 10 BB subjects, each tested twice in independent experiments.

^bP was calculated by Student's t test. NS, nonsignificant difference.

^cControl refers to cells not stained with DCF.
