When he has stopped breathing, we open the chest cut either the aorta or (hopefully through st. ventricle) the vena cava, perfuse first a little Ringer's (reptilia (?) and then fixative until the heart stops beating. The perfusion apparatus I had rigged up has been not very satisfactory etc etc etc. Then I have excised 2 pieces of lung tissues (for the same sites fixation: overnight in all animals) and put it in fresh fixative overnight. up in an oil Really, have needed a better apparatus or a board for holding the for 2 hrs. - animal. 2Os - 0.1M CaCO3. 3 hrs in UAc, dehydrate.
