Spermine induces precocious development of the spleen in mice.

abstract：:Rat hippocampal neurones in primary culture exhibited directional growth in response to DC electric fields. Neurites lay perpendicular to the field after exposure to 28, 80 or 219 mV/mm but there was no orientation effect at 9 mV/mm or in unexposed control cultures. Fields that evoked perpendicular responses also redu...
