    Summary
    An increase of synaptic density has been found in the hippocampus, the dendate gyrus and in the entorhinal cortex of 6-week-old rats after 7 days of treatment with the peptidergic drug Cerebrolysin, its peptide preparation E021 and the diluted peptide preparation E021dil.

    Slices of brain were stained immunohistochemically with anti-synaptophysin, a specific marker of presynaptic terminals.

Studies that did not test the peptide alone5

In this study, Cerebrolysin was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Cerebrolysin.
