Gastric xanthoma which is not a true neoplasm and clinically insignificant consists of the small yellowish lesion of the gastric mucosa, frequently of multiple occurrence. Histologically the lesion shows chronic superficial gastritis with intestinal metaplasia and occasional collections of foam cells within the lamina propria. Electron microscopically. the xanthoma, cells are composed of. lipid-laden histiocytes with. many autophagocytic Iysosomes surrounding the cytoplasmic lipid vacuoles. Many residual bodies are also noted. The pathogenesis of the gastric xanthoma is obscure, however it is thought that a previous focal lesion of the gastric mucosa may have been a factor. One case of gastric xanthoma is reported here and a brief review of literature is also made.

A two-year-old male peacock (Pavo cristatus) showed acute watery green diarrhea, followed by neurological signs including torticollis and muscular tremor. By the hemagglutination inhibition test for detecting the antibody against the Newcastle disease virus (NDV), the peacock serum inhibited the agglutination of chicken red blood cells. Grossly distinctive hemorrhagic lesions were found in the mucosa of proventiculus and intestine and lung. The spleen revealed multiple variable sized necrotic foci. Histologically, the mucosa of gastrointestinal track had hemorrhagic lesions and some of them underwent ulceration. The spleen exhibited multiple variable sized necrotic foci in which fibrin exudation was marked. Central nervous system had mild non-suppulative menin-goencephalitis consisting of vasculitis, perivascular hemorrhage, gliosis and meningitis. The cells particularly in the cerebellum were degenerative to necrotic. Some of these nerve cells revealed characteristic peripheral chromatolysis. From the present serological and pathological findings, it is suggested that NDV causing death of peacock was velogenic viscerotropic strain. This is the first report of the occurrence of velogenic viscerotropic NDV in an adult peacock in Korea.

Rectal stricture occurred in 2 finishing pigs submitted for necropsy from Moguchon, the meat processing plant, chonbuk. Grossly, the wall of the rectum was harden and thickened by fibrous tissue. Anteriro to the stricture, the descending colon was dilated up to 30cm in diameter, filled with gas and pasty green fluidal feces. Histologically, the epithelia of rectal mucosa were necrotized. The mucosa and submucosa of rectum were infiltrated by macrophages, eosinophils and lymphocytes. This infiltration was the most extensive in the deeper layer of submucosa and intensive fibrosis was observed in deeper submucosa layer. This case is report for rectal stricture of finishing pig.

Verrucous carcinoma is a distinctive form of low-grade squamous cell carcinoma. The tumor has an exophytic, cauliflower-like appearance, and usually occurs in males and tends to affect individuals over 60 years of age. It typically involves the oral cavity, larynx, esophagus and skin. Most intraoral cases involve the mandibular vestibule, the buccal mucosa and the hard palate. The cause is unknown, but most verrucous carcinomas arise from the oral mucosa in people who chronically use chewing tobacco or snuff. The treatment of oral verrucous carcinoma remains controversial. Whenever possible, surgically total excision and skin or mucosal grafting is recommended. After total excision of huge verrucous carcinoma,instead of dermal or mucosal grafting, we used artificial dermis silicone membrane. We had a good result without recurrence and present this case.

The purpose of the current study was to evaluate the effect of the zinc-deficient diet on the connectine tissue of oral mucosa in the albino rats. The zinc dificient diets were supplied to the rats for 4 weeks. The results were as follows: Most of the papillas of lamina prmina propria were shortened. The abnormal distribution and orientation of the fibrous elements were observed. The stain ability of fihrous elements in the Mallory azan stain was decreased. The amorphous intercellular substance showed slight metachromasia in the toluichine blue stain and low PAS reactinity.

Peri-implant diseases are inflammatory lesions, which include peri-implant mucositis and peri-implantitis. Peri-implant mucositis is described as the presence of inflammation in the mucosa around implants without any bone loss. By contrast, in peri-implantitis, besides the inflammation in the peri-implant mucosa, loss of supporting bone is also seen. Diagnosis of peri-implant diseases require the use of gentle probing(0.2 ~ 0.3N) to identify the presence of bleeding on probing, probing depth and suppuration, both signs of clinical inflammation. Radiographs are required to detect loss of supporting bone. Baseline probing measurements and high quality, long cone periapical radiographs should be obtained once the restoration of the implant is completed to make possible longitudinal monitoring of peri-implant tissue.

Acromegaloid Facial Appearance syndrome is a very rare syndrome combining acromegaloid-like facial appearance, thickened lips and oral mucosa and acral enlargement. Progressive facial dysmorphism is characterized by a coarse facies, a long bulbous nose, high-arched eyebrows, and thickening of the lips, oral mucosa leading to exaggerated rugae and frenula, furrowed tongue and narrow palpebral fissures. We report a case of acromegaloid facial appearance syndrome in a 19-year-old male patient who presented with all the characteristic features of the syndrome along with previously unreported anomalies like dystrophic nails, postaxial polydactyly and incisal notching of teeth.

Mucosa-Associated Lymphoid Tissue(MALT) lymphoma is the most common extranodal B cell lymphoma among peripheral one. Although palatine tonsil is common origin among Waldeyer's ring, there is no presented case in Korea. This lymphoma is known to be less invasive than other subtype of low grade B cell Non-Hodgkin lymphoma. Because MALT lymphoma has a tendency of localizing one area for a long time, there are many cases treated by local treatment like radiotherapy, or local excision and radiotherapy. We report a case of MALT lymphoma originated from left tonsil.

This study was carried out to evaluate the irritant potential of A mouthwash in hamster cheek pouch. The test substances were applied twice daily to right pouches of hamsters for 14 consecutive days. Animals were administered with A mouthwash, Listerine, saline and control solution, respectively. In order to evaluate the irritant potential in mucosa of hamster cheek pouch, we observed clinical signs, mortality, body weight changes and gross and histopathological findings for 14 days. In all groups, there were neither dead animals nor significant changes of body weights. In addition, there were no differences between saline and A mouthwash treated group in gross and histopathological findings. Therefore, these results suggest that there was no irritant potential of A mouthwash in hamster cheek pouch.

In spite of the radical increase of chemical poisoning cases caused by prevalent of oranic chlorine like endosulfan, the study of detection of chemical poisoning has seldom been attempted; the study of poisoning in teeth, which is more secure physiochemically, and in all the oral tissues has been even less attempted. The author has administered endosulfan into the month of a rabbit, causing its death, and tried to detect endosulfan in the teeth, jaws, and oral tissues through forensic chemical and histopathological tests. The result obtained is as follows : 1. By thin layer chromatography, endosulfan was detected in the jews, dental hard tissues, dental pulp, blood, and the liver. 2. By gas chromatography, it was also detected in the jaws, dental hard tissues, dental pulp, blood, and the liver. 3. The congestion and hemorrhage in buccal mucosa, palatal mucosa, and dental pulp was detected.
