Prostaglandin E2metabolism in rat brain: Role of the blood-brain interfaces

Table 1 Prostaglandin dehydrogenase specific activity in tissues from 2-day-old and adult rats.

	2-day-old	Adult
Lung	1.64 ± 0,42 (5)	0.47 ± 0,08 (5)
Kidney	2.29 ± 0,23 (7)	0.93 ± 0,16 (6)
Cerebral cortex	ND	ND
Fourth ventricle choroid plexus	0.10 ± 0,02 (3)	0.027 ± 0,012 (6)
Lateral ventricle choroid plexus	0.19 ± 0,05 (3)	0.025 ± 0,018 (5)
Cerebral microvessels	na	ND

Data (in nmol.mg protein^-1.min^-1) are expressed as mean ± SE (n). ND: not detectable. na: not available (see text). The detection limit was calculated as being 0.02 for microvessel and choroidal preparations, and 0.01 for cerebral cortex.
