Plasma hydrazine levels

	Time Interval Since Last INH dose	VEH-INH	BNPP-INH	t-test
Plasma Hydrazine at 24 h (μM)	15 h	12.1 ± 4.6	6.1 ± 0.9	p = .22
		n = 15^3-a	n = 4^3-a
Plasma Hydrazine at 32 h (μM)	2 h	31.8 ± 2.8	8.2 ± 1.8	p < .00001
		n = 14	n = 13^3-a

↵3-a Plasma hydrazine levels were below the quantitation limit (4 μM) in one animal in the VEH-INH group and 12 animals in the BNPP-INH group at 24 h and in three of the animals in the BNPP-INH group at 32 h.
