Example text

Within 1-2 min, 0-02 ml of solution spreads over little more than 1 cm2 of surface. It is evident that some of the material remained in the anterior unciliated area of the nose while the rest moved in various streams, more or less directly, toward the nasopharynx. While some material reached the nasopharynx within 6-10 min, much lagged behind and reached this point some minutes later. Patterns of distribution and speed of flow varied considerably between subjects. It should be remembered that one or more minutes were required for completion of each scan, and some 15-30 sec were lost between each two scans.

Dr. PROCTOR replied that in the studies with the smaller particles of 5-15 microns, or with the solution of sodium iodide, the material was placed on the surface, and not administered in the re­ spired air. Only a few studies of the smaller particles had been done and there appeared to be no difference between the clearance of the large and the smaller aggregates, nor of the solution itself. Mr. A. G. HEPPLESTON (Department of Pathology, Royal Victoria Infirmary, Newcastle- uponTyne, England) asked if Dr.

The subjects experienced no unpleasant sensation, and there was no tendency to sneeze when this site was chosen. Immediately after injection the subject lay prone on the scanning table with the head turned to one side so that the plane of the nasal airway was parallel to the table top. The first scan was begun as quickly as possible and was usually completed within 3 min after the injection. Immediately upon its conclusion a series of sub­ sequent scans was done as quickly as possible and continued until a portion of the radioactivity was detected in the pharynx (Figs.
