  • The intact dental pulps which were free of their tooth bud from adult rat incisors, and oral mucosa were transplanted subcutaneously in homologous rats to study the formation of calcified tissue. The rat were sacrificed after 1,2,3 and 4 weeks following transplantation of dental pulp and oral mucosa. The samples which contained the transplanted and surrounding tissue were fixed in 10% NBF, stained with hematoxylin and eosin, alizarin red S, von Kossa, and alcian blue. Microscopic examinstins revealed as follows: 1. The transplanted oral mucosas were not calcified but tended to form the epithelial cysts. 2. At 1 week after transplantation of dental pulp the calcified structures were appeared at the periphery of the transplantation of dental pulp but weakly reacted to alizarin red S, von Kossa, and alcian blue. 3. At 2 weeks after transplantation of dental pulp the calcified structures began to expand from the periphery to the center of the transplanted dental pulp and occupied the large areas comparatively, and strongly reacted to alizarin red S, and von Kossa stains. 4. At 3 weeks after transplantation of pulp tissue the fibrous components were grown at the periphery of the transplanted pulp tissuesand at 4 weeks a large amount of fibrous tissues were observed. The transplanted pulp tissue tended to form foreign bodies gradually.

  • Objectives In the past, studies have been shown that Forsythiae Fructus (FF), Ulmi Cortex (UC) and JwaGwiEum (JGE) are effective in treating allergic reactions. However, no report shows the difference in effects of FF, UC and JGE in allergic rhinitis (AR). Therefore, the purpose of this study was to differentiate the effects of FF, UC and JGE in AR induced by ovalbumin (OVA) in mice. Methods From this experiment, the effects of FF, UC and JGE were several - changes in body weight, hematologic changes such as WBC, RBC, Hb and PLT counts, immunological changes such as levels of histamine, IgE, IL-4 and expressions of iNOS & COX-2 mRNA. Moreover, histological change of nasal mucosa was also investigated. Results FF administration group and JGE administration group significantly inhibited level of IgE compared to the control group. Also, FF administration group, UC administration group and JGE administration group inhibited IL-4 and expressions of iNOS & COX-2 mRNA. In histological assessment, FF administration group, UC administration group and JGE administration group showed reduced amount of subepithelial edema, desquamated mucosa and hyperplasia of basement membrane from OVA.

  • A 2-year-old female Maltese dog was admitted with a history of pyometra and resulting peritonitis and septicemia. Uterine specimen sampled by ovariohysterectomy was processed routinely for histopathological observation. Grossly, the uterine mucosa was covered with necrotic debris and on the cut surface, lesion extended into the uterine wall. Microscopically, severe necrosis was observed throughout thickened mucosa, submucosa, and wall of uterus. Tumorous lesions composed of anaplastic cells with bizarre nuclei or tubular structures of cuboidal to short columnar cells were infrequently observed around the necrotic lesions and muscular layer far from necrotic areas. Immunohistochemically, central necrotic area with ambiguous cell and tissue structures, peri-necrotic tumor lesions, and muscular layer were strongly positive for cytokeratin. Since huge necrosis of adenocarcinoma lesions in this case made it difficult to diagnose, immunohistochemical results enable to diagnose as a severe necrotizing adenocarcinoma. Thus, histopathological and immunohistochemical findings in this case may serve as an important knowledge to diagnose uterine adenocarcinoma with huge necrosis in the veterinary field.

  • Effects of cheonggukjang on immunohistochemical reactions in gastrointestinal (GI) tract of rats were investigated. $CD4^+/CD8^+$ immunoreactive cells of cheonggukjang-fed diet groups were more strongly stained in lamina propria of mucosa and submucosa than those of basal diet group. Universal nitric oxide synthase immunoreactive density in colon was mildly stained in surface epithelium and mucous secretory gland, and strongly stained in submucosa and myenteric plexus in muscle layers of all cheonggukjang-fed diet groups. Protein kinase C-${\alpha}$ immunoreactive cells in colons of 15 and 25% cheonggukjang-fed diet groups were more strongly stained in mucosa, submucosa, and muscle layers than those of basal diet group. These results indicate mucosal immune activity, gastrointestinal motility, blood circulation, and physiological activities of enteroendocrine cells in GI tract could be increased with cheonggukjang intake.

  • Erythema multiforme(EM), a blistering and ulcerative inflammatory disorder, affect skins or mucosa, and is thought to be triggered mainly by preceding infection, such as Herpes simplex virus, or exposure to drugs and medication, particular antibiotics or analgesics. Symptoms include typical cutaneous target lesions on skins and in case of oral manifestation, erosive and ulcerative lesions on lips, buccal mucosa, and tongue are known to occur, which needs differential diagnosis with other intraoral lesions. In this case, EM assumed that it is occurred by giving Trichomonas infection or Metronidazole in oral region is introduced with a review of diagnosis and treatment of EM.

  • Out of all oral malignant tumor, malignant lymphoma occurs in only 3.5%. Especially, most of the primary malignant lymphomas, which occur in the head & neck region are high-grade diffuse large B-cell lymphoma and mucosa-associated lymphoid tissue (MALT) marginal zone B-cell lymphoma is very rare. In the head & neck region, malignant lymphoma is reported to occur in the thyroid, salivary gland, trachea, larynx, orbital lobe and the Waldeyer's ring. Among the Waldeyer's ring, palatal tonsil is reported to be the most common region, but, only 1 case report was published in Korea. Until now, there were no case reports of MALT lymphoma that occurred in the tongue. The purpose of this case report is to report and discuss on a case of MALT lymphoma of the tongue.

  • The Varicella zoster virus is responsible for two common infectious diseases: chicken pox(Varicella) and shingles(Herpes zoster). Chicken pox is the primary infection. After the initial infection, the virus remains dormant in sensory ganglia until reactivation may occur decades later. The subsequent reactivation is Herpes zoster. Herpes zoster of the trigeminal nerve distribution manifests as painful, vesicle eruptions of the skin and mucosa innervated by the affected nerve. Oral vesicles usually appear after the skin manifestrations. Reports of osteomyelitis of jaw after trigeminal herpes zoster are extremely rare. We report a case of osteomyelitis on mandible caused by herpes zoster infection which was treated by antiviral drug, curettage. At 1 year post-operatively, mandibular mucosa had healed without recurrent sign. But post-herpetic neuralgia is remained.

  • Objectives : In this study, we investigated the effect of Saposhnikoviae Radix on allergic responses in ovalbumin(OVA)-induced Allergic rhinitis(AR) mice. Methods : BALB/c mice were orally administrated with Saposhnikoviae Radix water extract (SRW, 50 mg/kg) or anti-histamine drug, Ketotifen (10 mg/kg) as a reference drug, followed by sensitization and challenge of OVA. Mice were measured clinical symptoms and the serum levels of histamine, IgE, IL-4, and IFN-${\gamma}$, and observed histopathological changes of nasal mucosa H&E staining. Results : SRW significantly decreased rubs and the serum levels of histamine, IgE, and IL-4, and then increased the serum levels of IFN-${\gamma}$ in OVA-induced AR mice, and inhibited histopathological changes of nasal mucosa with inflammation and the eosinophils infilteration. Conclusions : These data suggest that SRW has anti-allergic effect through the inhibitory property of Saposhnikoviae Radix against allergic responses in allergic rhinitis.

  • Background & Objectives : Rhinitis is an inflammation of nasal mucosa. The major symtoms are watery rhinorrhea, sneezing, itchy nose, and nasal obstruction. Allergic rhinitis is an immune reaction by allergen. So, we aimed to determine therapeutic effects of Acorus gramineus by observing changes in IL-4, $IFN-{\gamma}$ and the nasal mucosal tissue. Materials and Methods : Fifteen BALC/c mice were divided into three groups : m group(which ate low concentrated herbal medicine ), M group(which ate high concentrated herbal medicine) and control group. Control and experimental group were induced allergic rhinitis by Ovalbumin as the method of Levin and Vaz. Experimental group was orally administered the Acorus gramineus extract for 28days. We observed changes in IL-4, $IFN-{\gamma}$ and trans aminase(AST, ALT) in blood and nasal mucosa and submucosa. Results : There were no significant changes statistically in IL-4 and $IFN-{\gamma}$ in blood(p<0.05). And there were no hepatotoxicity with Acorus gramineus extract. Histologically, almost no inflammatory response in treatment group(m,M) against that there were inflammatory response(increased goblet cells, dilated vessels, edema of bowman's glands and injured olfactory hairs) in control group. Conclusion : According to above results, it is supposed that Acorus gramineus has no immunological effects on allergic rhinitis.

  • Based on the gross lesion, a survey of ulcer prevalence was carried out on pigs (3,161 heads) at a slaughterhouse in seoul from April to December in 1989. The pigs stomachs were observed anatomically and classified, according to the presence or absence of foreign bodies. Ulcer prevalence is usually classified according to size of pig farm, ages, and supplied month. The results in the studies were as follows, 1. Fundus followed the highest rate with 28.2%, esophagus with 24.5% each of cardiac and pyloric part with 7.8% and 4.1% in cases of gastric mucosa pathological studies examed total 3,161. In the acute ulcer prevalence, fundus follwed with 5.4%, esophagus with 2.6%, each of cardiac and pyloric part with 0.8% and 0.3%. When prevalent frequencies of fundus are compared with cardiac and pyloric part, they have meaning.(P <0.05). 2. In the survey pig of total 3,161, pathological changes of epithelium tissue foliowed 44.0%, erosion(11.5%), chronic ulcer(14.8%), acute ulcer(1.6%), scar formation (1.7%) and perforation (0.9%). 3. In general monthly prevalence rates of gastric lesion are higher in spring and fall than in summer. 4. In the size of pig farms, ulcer showed higher rate at professional farms than raising on the side. 5. When there are more fluid condition in stomach and they are old, the ulcer appeared for more. 6. Foreign bodies in stomach were sand, hairballs, and intestinal worms were detected (1%).
