A cineradiographic method for recording the function of the oesophageal groove in lambs.
Using a TUR-D1001 X-ray unit and electronic image intensifier ZOX 190T-Chirana with an Admira 16 film camera the authors recorded the contractile function of the oesophageal groove in lambs. After an adaptation of the animals to the experimental conditions the lambs were given a contrast medium mixed with milk from a bottle with rubber nipple. The flow of the contrast through the terminal-part of the oesophagus, oesophageal groove and the canal of the omasum was recorded on a film, the rate of film taking was 16 frames per second. The analysis of the film showed that in lambs aged 2 weeks the passage of the contrast medium through oesophageal groove and omasal canal was slower than in adult animals. The film visualizing the function of the groove is of considerable instructive value.
