[The neuromorphological basis of the therapeutic action of neurohumoral factors from the cerebrospinal fluid].

The influence of the donor's cerebrospinal fluid (CSF) on retrograde transport of horseradish peroxidase (HRP) from lumbar cord segments to neurons of the sensomotor cortex (SMC) in rats after the left SMC damage was studied. The CSF of convalescents (21 days after damage) and CSF of normal rats was shown to activate the transport of HRP to neurons of the SMC of undamaged hemisphere in the recipients (second day after damage).
