Table 1 The I125-β NGF level in brain and blood by vein injection (Ci/g, n=8)

From: Permeability and distribution of nerve growth factor in the brain of neonatal rats by periphery venous injection in hypoxic-ischemic state

Group Adult rats Normal neonatal rats Neonatal HI rats
Brain 51.21 ± 3.40# 130.74 ± 6.84** 165.83 ± 8.74*
Blood 1798.61 ± 116.66 1908.96 ± 62.71 899.89 ± 162.96
Percentage% 2.86 ± 0.25# 6.85 ± 0.50** 8.75 ± 0.33*
  1. The adult rats’ brain can detain the fewest NGF at (2.86 ± 0.25)%, normal neonatal rats ranked the middle at (6.85 ± 0.50)% and neonatal HI rats can detain the most NGF at (8.75 ± 0.33)%
