Glutathione (GSH) toxicity data. Doses of GSH were injected into quail eggs 24 hours after incubation. At 8 days of incubation, the embryos were examined to determine survival and identify those with gross head and body defects.

Treatment (n)	Survival rate (%)	Survivors with gross head/body defects (%)
Saline vehicle control (54)	48 / 54 (89)	0 / 48 (0)
Uninjected control (82)	74 / 82 (90)	2 / 74 (3)
100 nmol GSH (30)	27 / 30 (90)	3 / 27 (11) p<0.043
1 µmol GSH (27)	21 /27 (78)	2 / 21 (10) p=0.09
10 µmol GSH (24)	22 / 24 (92)	1 / 22 (5)
100 µmol GSH (24)	21 / 24 (87)	2 / 21 (10) p=0.09
1 mmol GSH (54)	43 / 54 (80)	4 / 43 (9) p=0.046
10 mmol GSH (47)	45 / 47 (96)	1 / 45 (2)
