Ring-stabilization technique for collection of avian air sacs.
Histologic features of chicken air-sac membranes harvested with rings were compared with those of membranes collected on cards. Ring stabilization of the tissues throughout fixation, dehydration, and embedment was found to reduce markedly the artifacts and the loss of normal tissue architecture observed within the wall of card-collected air sacs.
