In this chapter, diseases of the gastrointestinal tract that primarily affect areas other than the oral cavity are discussed. This chapter is not intended to be a complete review of all diseases affecting the gastrointestinal tract; rather, emphasis is on the medical aspects, the dentist’s role as a primary health care provider in screening for undiagnosed conditions, and the dentist’s role in ...
Although polypectomy by high frequency electric surgery through the use of endoscopy has been widely applied to polypoid lesions in digestive canals, there have been very few reports of the treatment of bronchial lesions with this procedure. Recently, we have been successful in performing polypectomy without any complications using high-frequency electric surgery through a flexible bronchoscope...
A mong the most striking avian anatomical divergences from the typical tetrapod pattern is the reduction of the cephalic alimentary canal to a bare minimum required for food procurement, generally believed to be an adaptation for lightening the avian body for flight (1). Much of this anatomical modification involved jettisoning teeth concomitantly with the acquisition of a horny beak, the reduc...
In the present study, we evaluated the histological morphology of the adult Paramphistomum (P.) gracile. Adult flukes with bodies 5~15 mm in length and 2~7 mm in width were subjected to histological analysis. Longitudinal and transversal serial-sections were stained with hematoxylin and eosin, and examined. The body surface and longitudinal section of P. gracile were also assessed using scannin...
IN 1896, when I was a first-year medical student, Professor Henry P. Bowditch, whose memory his former students delight to recall, invited me to make use of the then newly discovered Roentgen rays in a study of the activities of the alimentary canal. In December of that year we demonstrated to the members of the American Physiological Society the passage down the esophagus of a swallowed mass m...
Introduction Mycoplasmas are normal inhabitants of the upper respiratory airways, urinary and genital tracts, and the digestive system; however, they can become infectious and cause high impact diseases in dairy herds including mastitis and metritis. In dairy cattle, Mycoplasma bovis is the most commonly isolated mycoplasma species (spp.). This species is very invasive and capable of colonizing...
DAS-ELISA, immunohistochemistry and electron microscopy were used to investigate the association of the causal agent of bacterial wilt, Erwinia tracheiphila (Smith), within the beetle Acalymma vittatum (F.). After a 24-h acquisition period, a high percentage of individuals tested positive for E. tracheiphila antigen using both immunohistochemistry (100%) and DAS-ELISA (70-60%). Both assays show...
The occurrence of phthalate esters in freshwater and marine aquacultural species like rainbow trout Oncorhynchus mykiss and shi drum Umbrina cirrosa, respectively, were determined by immunohistochemical approach. The results showed a similar distribution in the gastrointestinal tract of both species. In particular, intense immunoreactivity was found at gastric gland level. In the intestinal tra...
Oscillibacter valericigenes is a mesophilic, strictly anaerobic bacterium belonging to the clostridial cluster IV. Strain Sjm18-20(T) (=NBRC 101213(T) =DSM 18026(T)) is the type strain of the species and represents the genus Oscillibacter Iino et al. 2007. It was isolated from the alimentary canal of a Japanese corbicula clam (Corbicula japonica) collected on a seacoast in Shimane Prefecture in...
