Chris van der Loos at the Dept of Cardiovascular Pathology, Academical 
Medical Centre, Amsterdam, The Netherlands writes about methacarn fixative:

>>Our Japanese collaborators in Osaka who came up with it even store whole 
hearts in methacarn!!<<

They hardly came up with it - it was invented by Holde Puchtler at the U of 
GA maybe 25 years ago. Susan Meloan, can you elaborate??
