Histotopography of the pyloro-duodenal glands

, : Histotopography of the pyloro-duodenal glands. K Danske Videnskab Selskab Biol Meddelel 19(9): 1-22

Esophagus, stomach, and duodenum were examined, some with binocular dissecting microscope, in 10 human fetuses (2.1 to 7 lunar months), 3 children, and 10 adults with no digestive trouble. Fixation, often a few mins. after death, was by intraabdominal injn. of formaldehyde. The stains were hematoxylin-eosin, azan, and alkaline mucicarmin. The zone occupied by cardiac glands was 1/2[long dash]1 cm. and by pyloric glands 3-5 cm. Frequently a transitional zone contained intermingled pyloric and fundic cells. Brunner's glands formed an almost compact layer from pyloric sphincter to duodenal ampulla, but decreased toward the duodeno-jejunal flexure. In fetuses, the pyloric and cardiac cellular zones were extensive compared with the fundic zone.

HLA-A,B,C and HLA-DR molecules are involved in cognate LFA-3 (CD58) in antigen-independent T-cell/target-cell interaction. T-cell-mediated host-versus-tumor response might therefore depend on the presence of both types of molecules on the surface...
