摘要: Abstract 1. The protein composition and concentrations of total in cerebrospinal fluid (CSF) plasma opossum ( Monodelphis domestica ) from birth until adulthood have been estimated. 2. Total CSF increased to a peak concentration between 5 10 days (500 mg/100 ml) after which it declined rapidly. 3. started at low level (below 400 progressively the adult value (8500 ml). 4. Proteins identified were: albumin, alpha 1 antitrypsin, transferrin, 2 macroglobulin, lipoproteins immunoglobulin G. A fetal protein, probably alpha-fetoprotein, has identified. 5. only proteins found within brain, even very immature newborn this species, appeared an intracellular rather than extracellular distribution. This indicates that blood-brain barrier is present early development there also CSF-brain appears exclude brain space.
