Description: Segment 1 Gilliland introduces Pearse. Pearse begins by explaining what the APUD cell series is and what the initials stand for. He then looks back at this history of the discovery of the theory with particular reference to the work of Fuller Albright. Time start: 00:00:00:00 Time end: 00:05:37:00 Length: 00:05:37:00 Segment 2 Pearse shows slides of enzymes within the pituitary gland and describes some early research into APUD cells located there. Time start: 00:05:37:00 Time end: 00:10:37:14 Length: 00:05:37:14 Segment 3 Pearse refers to tables listing APUD characteristics, then diagrams detailing the most effective methods for demonstrating the presence of APUD cells. Long, detailed tables are shown listing all the different types of APUD cells, 20 in total. A further table lists other cells not yet confirmed as APUD but suspected to be. Time start: 00:10:37:14 Time end: 00:15:15:00 Length: 00:04:37:11 Segment 4 Pearse shows the APUD-FIF technique for labelling cells and describes research into this method. Time start: 00:15:15:00 Time end: 00:21:10:18 Length: 00:05:55:18 Segment 6 Pearse recounts the research of Professor Feyrter into APUD cells. He shows a table which details the Wiesbaden agreement for naming endocrine cells in the stomach and intestine and an illustration of gut endocrine cells. Time start: 00:24:22:00 Time end: 00:29:39:00 Length: 00:05:17:00. Segment 7 Pearse a slide of a television analyser and describes the kind of pictures it makes. Pearse then discusses different types of apudomas, describing them and outlining treatments. Time start: 00:29:39:00 Time end: 00:35:24:00 Length: 00:05:45:00. Segment 8 Pearse looks at the types of cell primarily involved in apudomas. He then summarises and recounts the main points of the lecture.
