Short Title of Projects The Effect of Cigarette Smoking on the Ultramicroscopic Structure of the Bronchial Mucosa 4. Proposed Renewal Starting Date: (Anniversary or other) December 1, 1967 5. Discuss any Important Changes or Additions to Objectives or Specific Aims: • Recently in the bronchial mucosa from an adult, non-smoking patient, some -structures have been seen which have the typicaL morphological appearance of tumor whether these virus-like bodies can be identified in other individuals, both in the bronchial mucosa and in lung tumors. For this reason, I plan to broaden the scope `of the study to include study of the ultramicroscopic structure of lung cancers. If ,neoplasms cannot be.decided at this time. However, further study is indicated to see ; particular biopsy. Whether they are oncogenic or in any way related to bronchogenic virus (Figures 1 & 2). These virus-like bodies were seen in several cells from this '-~..:-these virus-like bodies can be recognized in lung tumors, then further study will be ,justified to determine whether they have oncogenic properties. Representative photomicrographs of some recent biopsies are attached (Figures 3-10). Up until now it has been impossible to obtain bronchial biopsies in normal individuals and we have had to rely on patients who are undergoing lung resection and in whom there was no clinical~or pathological evidence of bronchial mucosal ab- normality. I have now been able to make arrangements with Children's Hospital of Michigan to obtain bronchial biopsies from children undergoing lung resection for removal of congenital pulmonary abnormalities, and as a result we will be able to ~A obtain bronchial tissue which probably can be regarded as normal.

My original technician is now working on a part-time basis because of domestic problems, but as well, I have another part-time technician who is an undergraduate student in Biology at Wayne State University. Between the two technicians I have the equivalent of a full-time technician. *0. Publications or Papers in Press resulting from the Project or closely related work

M49DSE001 FIGURE 1. A cell in the bronchial mucosa showing large cisternae which probably represent Golgi organ. In the surrounding cytoplasm are numerous vacuoles, some of which contain virus-like bodies consisting i n of a central core with a surrounding two or three-layered concentric wall. These are better, seen the next figure.

FIGURE 3. This photomicrograph was obtained from a man who was a heavy smoker and shows the luminal surface of a ciliated cell with several cilia which appear normal and a great deal of pellicular material between the cilia. This pellicular material is a branching form of particularly large microvilli and greatly increases the specific surface area of the cells. On the right hand side there is a dark cell which is an exhausted goblet cell. The microvilli on this cell are covered with "whiskers", which are seen in greater detail in Figure 4.

( FIGURE 4. Shows the microvilli with "whisker" formation. This has been noted frequently on cells which appear to be exhausted and about to be shed into the bronchial lumen. On the left, the pellicular material is seen in greater detail. .

i FIGURE 5. This is a cross-section of the tracheal mucosa and shows cells in the process of being shed into the tracheal lumen. The cell nearest the lumen on the right has a light cytoplasm and very little intracellular structure. The intercellular processes which are normally interlocking are well seen.

FIGURE 6. This was also obtained from the tracheal mucosa, but shows a cell in the process of being expelled into the lumen.
