STUDIES ON BLOOD-BRAIN BARRIER WITH RADIOACTIVE PHOSPHORUS

摘要: SHORTLY after the discovery was made that central nervous system cannot be stained by intravenous injection of vital dyes and concept a blood-brain barrier established, question arose: Does or does not this exist at birth? The phenomenon kernicterus seemed to indicate in newborn infant is yet fully developed, experiments with young animals gave some support inference. evidence these offered certain, however. Moreover, early investigations yielded contradictory results. It thought application radioactive phosphate would clarify matter development blood-barrier also reveal whether similarity exists, intrauterine postnatal stage, permeability pigments (bilirubin), dyes, ions (P32). analogy between response
