Gastric adenocarcinoma of fundic gland type is known to originate from the gastric mucosa region without intestinal metaplasia. It difficult detect during endoscopy and diagnose histopathologically. The development immunohistochemistry has enabled diagnosis by phenotype. A 34-year-old man visited us for treatment a 5 cm-sized low-grade dysplasia in fundus which was incidentally found health che...

In order to show the type and severity of gross and histopathologic lesions induce by vaccinal strain (serotype A1) of Pateurella mulocida, ten four-week-old SPF chickens were inoculated intramuscularly with 75 cfu of ( 0.5 ml of 10-7 dilution) bacterium. All birds died in less than 16 hours. No prominent gross lesions were observed in different organs. In microscopic examination, the most comm...
