[Effect of strychnine, morphine and serotonin on dry weight dynamics in cultivated glial cells]

The dry mass of glial cells was studied after their introduction into nutrient media or application of neurotropic drugs (strychnine, morphine and serotonin). Drug concentrations disturbing synchronous fluctuation of dry mass of contracting glial cells were established (0.025 and 0.25% for strichnine and morphine, resp.). Similar changes were induced by a local application of strychnine and serotonin to a confined region of the cell membrane of one of the contracting cells.
