Complement activation in the Parkinson's disease substantia nigra: an immunocytochemical study

Table 1 Subject ages and post-mortem intervals.

Group	n	Age (yrs)	Age range	PMI (hrs)	PMI range (hrs)
YN	11–13	43.2 ± 1.9^a	24–53	15.8 ± 2.0	3.0–24.0
AN	24–28	83.7 ± 2.1	66–104	10.8 ± 1.4	0.3–23.0
PD	19–20	80.2 ± 2.1	66–91	11.2 ± 2.3	2.0–29.0
AD	12–13	76.8 ± 1.9	61–83	7.4 ± 1.6	3.0–23.3
DLB	9	78.3 ± 1.9	70–86	8.9 ± 2.0	1.6–16.3

PMI means were similar between groups, and subject ages differed only between young normal specimens and the other groups. Data are expressed as means ± SEM. (^ap < 0.05 vs. other groups; abbreviations: AD, Alzheimer's disease; AN, aged normal; DLB, dementia with Lewy bodies; PD, Parkinson's disease; PMI, post-mortem interval; YN, young normal)
