Ultrastructural aspects of Peptichemio action on mouse sarcoma 180

The electron microscope study of the cellular elements originating from mice experimental tumours (sarcoma 180) treated and non-treated with Peptichemio showed alterations of the nuclear and cytoplasmic structures in the animals treated. The data herein accord fully with the results obtained by other histological, biochemical and biomolecular techniques and make it possible once again to lay stress on the double alkylating and antimetabolic action of this antitumour drug, very likely taking place simultaneously both at nuclear and cytoplasmic level.
