Summary

  1. 1

    The histamine, histidine decarboxylase and gastrin content of the oesophagus, crop, glandular stomach, gizzard and duodenum was determined in chickens.

     
  2. 2

    Only minute amounts of histamine were found in the oesophagus (0.8 μg/g) and crop (0.5 μg/g). In the glandular stomach (7.7 μg/g), however, the gizzard (4.8 μg/g) and the duodenum (12.9 μg/g) the histamine content was considerably higher.

     
  3. 3

    Measurable amounts of the specific histidine decarboxylase activity were found only in the glandular stomach (25.3 nMole newly formed histamine/g · hr−1

     
  4. 4

    In none of the organs investigated, could any gastrin activity be definitely detected.

     
  5. 5

    From the experiments it was concluded that gastric acid secretion in chickens may be controlled by systems other than gastrin. The role of histamine in this process is uncertain.
