[Histonet] Perfusion fixation of pig lungs

The fastest (less advance surgery) and most effective perfusion would be
whole body under higher than physiological pressure.  See the discussion
in Microscopy Today, May 2006 issue, for some ideas.  You would need
about 5 gallons of liquid prewash, and 2 or 3 gallons of fixative, for a


See the link above for ideas of what is needed, but our fluid tanks are
not large enough.  You (or we) would rig something similar on some
Carboy Tanks.

Getting through the heart and applying fluid at 300 mm Hg, the pig will
be drained of blood in seconds.  Fixative can then be applied and will
get there faster, measured from the time the diaphragm or chest cavity
is punctured, than any other way I know of.

I hope that someone here can help me.


We are planning to do some research in pig lungs. Due to this
investigation it is very important to have a fast and effective


We will therefore try to make a perfusion fixation. But a pig is a very
large animal and therefore we would like to limit the fixation only to
the lung region, and not a full body perfusion fixation.


Is there anyone how has experience with perfusion fixation limit to only
one organ in pigs? 


All suggestion will be read with enthusiasm.


Experience from similar fixation methods in other animals is welcome as
