Effect of ZnMP and SnMP on tissue heme oxygenase activity

Treatment	Heme oxygenase, nmol bilirubin formed per mg/hr*
	Liver	Spleen	Kidney
Control	0.70 ± 0.09	8.19 ± 2.0	1.16 ± 0.16
SnMP	ND	2.76 ± 0.90**	ND
ZnMP	ND	2.90 ± 1.12**	0.91 ± 0.18

Animals were injected i.v. with a dose of 10 μM/kg body weight and sacrificed 48 hr later. ND, no detectable activity. 

^*Mean + SD. 

^**P < 0.025 compared with control.
