Summary
Rats were given the convulsant drugs, Picrotoxin or Metrazol intraperitoneally, and
then fed with food containing the anticoagulant, phenylindanedione (Danilone) for
10 days. Other rats received for 10 days food containing Phenylindanedione and depressant
drugs (Nembutal, Barbitone, Librium or chlorpromazine). All combinations of drugs
but not the single drugs produced a high incidence of internal hemorrhage, which was
fatal to some animals.
