    Notes: Summary The distribution of serotonin-immunoreactive cells in the lung of 4 species of reptiles was investigated. Serotonin-containing cells were found forming groups in the interconnecting septa in all 4 species studied, and also as solitary cells in Testudo graeca and Mauremys caspica. Serotonin-containing cells were also localized in the intramural ganglia of Pseudemys scripta elegans and Testudo graeca. The present study confirms that serotonin is widely distributed in the lung of vertebrates.

    Notes: Abstract The maintenance of gastrointestinal epitheliumintegrity requires a fine balance between proliferationand differentiation as well as protection againstgastric acid secretion. Transforming growthfactor-α (TGF-α) regulates these functions bybinding to epidermal growth factor receptor (EGF-R).This study was designed to identify the localization ofTGF-α and EGF-R in the rat gastroduodenal region. In the stomach, the surface and gastric pitcells showed staining for TGF-α antibodies in thecytoplasm and basolateral and apical membranes.TGF-α and EGF-R were observed in the supranuclearregion of the cells lining the gland. In the duodenum,the enterocytes coexpressed both TGF-α and EGF-Rin the supranuclear area. The EGF-R was also observed inthe apical membrane. Brunner's glands were positive for both TGF-α and EGF-R antibodies. Ourresults demonstrate the coexpression of TGF-α andEGF-R in the rat gastroduodenal area, which suggests afunctional role for them in the establishment and maintenance of the epithelialrenewal.
