Electron microscopic and morphometric study of rats exposed to 98.5 percent oxygen at atmospheric pressure. AMRL-TR-65-66.

Preliminary study on the microbial flora of normal human subjects in a restricted environment. AMRL-TR-66-59.

Thin film personal dosimeters for detecting toxic propellants. AMRL-TR-66-231.

A portable system for the detection of low concentrations of nitrogen tetroxide (N2 0 4 ), fluorine (F 2 ), and unsymmetrical dimethylhydrazine (UDMH) in air has been developed. The detection system is based upon the change of electrical resistivity of thin metal films when exposed to these gases. Silver metal films coated with appropriate salts proved to be applicable to the detection of all t...

Evaluation of immunoassay methods for prolactin in body fluids. AMRL-TR-66-113.

A practical immunologic assay to detect the hormone, prolactin, in body fluids was evaluated. Prolactin content was assayed using positive antiprolactin sera prepared in rabbits and test samples of serum, urine, and urinary extract from a borane exposed female monkey in micro-Ouchterlony gel diffusion and agglutination inhibition tests. The gel diffusion test gave qualitative results while the ...

Development of Fine Structural Damage to Alveolar and Capillary Lining Cells in Oxygen-poisoned Rat Lungs

Rats were exposed to 98.5% oxygen at 765 torr for 6-72 hr. The pulmonary changes were investigated by electron microscopy and by morphometric methods. A progressive thickening of the air-blood barrier, from the normal 1.5 to 3 micro after 3 days, was due primarily to enlargement of the interstitial space by accumulation of edema which was replaced secondarily by cells and fibrin. This was accom...
