Effects of dexamethasone and RU486 on D1D2 rat pup body weight and brain weight.

Treatment	Body weight, Mean ± SE, g (N = 6)	Brain weight, Mean ± SE, g, (N = 6)
NS	7.75 ± 0.04	0.314 ± 0.004
Dex	6.75 ± 0.08*	0.293 ± 0.004
DMSO	7.50 ± 0.09	0.309 ± 0.004
RU486	7.16 ± 0.08	0.312 ± 0.004
DMSO/Dex	6.83 ± 0.04	0.301 ± 0.004
RU486/Dex	7.08 ± 0.03	0.319 ± 0.004

N: number of pups.

Compared pups injected with dexamethasone (Dex) and normal saline (NS) by using Wilcoxon rank sum test, *P < 0.05.

D1D2: administration on postnatal day 1 and sacrificed on day 2; RU486: mifepristone;

DMSO: dimethyl sulfoxide; DMSO/Dex: dimethyl sulfoxide plus dexamethasone;

RU486/Dex: mifepristone plus dexamethasone.
