Pulmonary intravascular macrophages in deer.

Pulmonary intravascular macrophages (PIMs) have been found in the septal capillaries of deer lungs. Lung samples from adult deer were fixed in 2.5% glutaraldehyde, and then routinely processed for electron microscopy.

Vascular tone could be increased by the release of TXA, (TXB, is the stable metabolite of TXA.J, which is a cyclooxygenase metabolite known to cause pulmonary artery constriction. Future experiments are directed at determining the mechanisms through which N macrophages are attracted and mobilized in the lung microvasculature and at which biologically ...
