Densitometric semiquantitative assessment of both Rhcg and Rhbg in the kidneys of control rats and rats maintained for 6 months on lithium.

Antibody	Control	6‐month lithium	P value
Rhcg papilla	100±42	67±19	NS
Rhcg outer medulla	100±37	154±17	<0.001
Rhcg cortex	100±41	71±10	NS
Rhbg papilla	100±37	158±62	NS
Rhbg outer medulla	ND	ND
Rhbg cortex	ND	ND

ND, not detectable; NS, not significant.
