About this work


A talk by Professor T. Chard from St. Bartholomew's Hospital Medical College. The following summary accompanies the videocassette: "Biochemical tests of fetoplacental well-being depend on the measurement in the mother of materials which differ from those in the nonpregnant adult. The two most popular tests at the present time are measurement of oestrogens and hPL. The main problems with these tests are the lack of information on the biochemical role of these materials and the very substantial overlap between normal and abnormal. Despite this, however, they have been shown to be of great value in a number of clinical situations and, in particular, in the diagnosis of intrauterine growth retardation. Recent developmetns include the introduction of new specific fetoplacental products, the evaluation of specific tests for placental transfer, and the use of biochemical tests as a screening procedure in all pregnancies."

This video is one of around 310 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and 1980s, thus constituting a contemporary medical-historical archive of great interest. The lectures mostly take place in a small and intimate studio setting and are often face-to-face. The lecturers use a wide variety of resources to illustrate their points, including film clips, slides, graphs, animated diagrams, charts and tables as well as 3-dimensional models and display boards with movable pieces. Some of the lecturers are telegenic while some are clearly less comfortable about being recorded; all are experts in their field and show great enthusiasm to share both the latest research and the historical context of their specialist areas.


Segment 1 Chamberlain introduces the lecture. Chard begins to talk about the three main ways of testing a foetus late in pregnancy. He shows a chart which lists the products of a human foetoplacental unit. Time start: 00:00:00:00 Time end: 00:04:57:15 Length: 00:04:57:15
Segment 2 Chard discusses the kind of enzymes likely to be found during pregnancy. Time start: 00:04:57:15 Time end: 00:10:03:15 Length: 00:05:06:15
Segment 3 A graph is used to show hormone level variation during the gestation period, for instance, the levels of urinary oestrogen. Time start: 00:10:03:15 Time end: 00:15:07:15 Length: 00:05:04:00
Segment 4 Chard shows a chart detailing the levels of human plancental lactogen during the gestation period. Time start: 00:15:07:15 Time end: 00:20:49:22 Length: 00:05:42:07
Segment 5 Chard and Chamberlain discuss Chard's lecture. They focus in particular on the cost effectiveness of antenatal care. Time start: 00:20:49:22 Time end: 00:25:45:22 Length: 00:04:56:00
Segment 6 Chard rounds up the lecture by discussing with Chamberlain his research into pregnancy bat-1-glycoproteins. Time start: 00:25:45:22 Time end: 00:34:29:04 Length: 00:07:44:07
