Shrunk neurons and TUNEL positive cell counts after Inhalation of smoke

Treatment Time Post Treatment Shrunk/Total Neuronsa TUNEL positiveb
Sham 1 week 0.022 ± 0.0015 2.0 ± 1.0
Smoke 1 week 0.019 ± 0.0004 2.3 ± 1.3
Sham 8 weeks 0.026 ± 0.0015 1.6 ± 1.3
Smoke 8 weeks 0.060 ± 0.0030* 5.7 ± 1.6*
Sham 10 weeks 0.025 ± 0.0015 2.3 ± 1.6
Smoke 10 weeks 0.071 ± 0.0012* 6.2 ± 0.3*

Values are means ± SD given as

a

ratios of shrunk to total neurons and

b

counts of TUNEL positive cells (n=3). Counting was done in a blinded fashion and each section was counted three times. Counts were analyzed by ANOVA for a two factorial experiment; the two factors were treatment (smoke inhalation or sham) and harvest time (1, 8, and 10 weeks).
