[Music therapy induced alternations in natural killer cell count and function].
The effects of music therapy on natural killer (NK) cell count and activity (NKCA) were studied in 19 persons. Alzheimer's disease, cerebrovessel disease and Parkinson's disease subjects were assigned to a music therapy. Blood samples were drawn at rest and after completion of music therapy. Music therapy did not change the number of circulating lymphocytes. The percentage of NK cells increased during music therapy, along with an increase in the NK cell activity. The proportion of T cells, CD4 and CD8 did not change significantly during music therapy. One hour after the music therapy session, plasma adrenaline increased but cortisol and noradrenalin did not change. The results indicate that music therapy can significantly increase NK cell count and activity. The change in NK cell and function were independent of neuro-degenerative diseases.
