Yes it does have actual journal references for many of the reports. He
does not exclude reports by private correspondance due to the nature of
DMSO research many clinicians were reluctant to attach their names to
the results and stated the anecdotal nature of the reports from the
outset.

I have checked on line sources such as Medline and Pub Med. There are
articles listed but no abstracts. I have not gone to the medical library
or ordered these journal articles yet. I am an hour away from that
particlular library and have not had a day to look up journal citations
in many months. Rest assured I will get to it, probably in the very near
future and will post what I find.

While I have respect for double blind studies I am much more inclined to
put the most faith in my own personal experience. Generally I start
there and then look for validation in others experiences and in journal
articles. However the journal articles often lag behind the personal
experiences by many years and in some cases hundreds of years. Strictly
speaking science is observation and requires no double blind studies. If
it did we would be tossing thousands of accepted medical precepts
accumulated over centuries of observation.

Part of the problem with viral studies is in defining dead and alive. In
rereading Goodman and Gilman's section on anti-viral agents in becomes
clear that this line is not clear when it comes to viruses. Terms used
in reference to viral affects are not "dead" or "kill", they are
"inhibit", "uncoat", intereferes with viral replication through affects
on the RNA or DNA processes and structures and similar descriptions of
activity. 

It becomes clear that the issue of virucidal as regards any anti-viral
agent is as much a matter of semantics and definition of terms as it is
of actual demonstration of effects.

DMSO is known to uncoat viruses. It is also known to stop viral
symptoms. It would appear this is as close as anyone is going to get in
defining its action against virues. And is a widely accepted level of
knowledge from which to go forth with therapeutic applications in the
absence of toxicity. DMSO has zero toxicity in therapeutic applications
and indeed requires inhalation of vapors upon boiling to some 370* or
consumption of 40,000 times the therapeutic dose, a highly unlikely
occurence. It has one of the safest therapeutic indexes (Therapeutic
Dose divided by the Lethal Dose in 50%) of any agent out there. 

Stedman's Medical Dictionary 22nd Ed defines virucidal and viricidal as
"destructive to a virus". With this definition in mind as well as the
terminology used by the standard in Clinical Therapeutics, Goodman and
Gilman, I believe the issue of discussing DMSO's ability to kill viruses
in vivo (in the body) is hampered by the current concepts of alive or
dead formed from knowledge of other life forms.

I would also remind those with high levels of curiosity as to the
mechansims of action of DMSO that many agents are still a mystery to us.
That does not stop use from using them for situations where we get
positive results.

I stated that DMSO kills viruses. I stand by that statement.
