Gastric cancer is the most common malignancy and the second leading cause of cancer-related death in Korea. Age-adjusted annual incidence of gastric cancer per 100,000 persons is 62.8 for male and 25.7 for female. The proportion of early gastric cancer among surgically treated gastric cancer patients was 28.6% in 1995, 32.8% in 1999, and 47.4% in 2004. Screening upper endoscopy is quite commonly performed in Korea, and the proportion of early gastric cancer in the screened population is almost 75%. Gastric adenoma is considered to be a very important precancerous lesion. Gastric adenomas are actively treated in Korea, and at least 1/3 of the gastric adenomas with high grade dysplasia show cancerous focus when endoscopically resected. The prevalence of Helicobacter pylori is decreasing in Korean population, which may lead to the decreased incidence of gastric cancer in the near future. Paradigms of the diagnosis and treatment of gastric cancer are rapidly changing in Korea. Efforts to establish robust scientific data for new approaches are strongly required. The proportion of early gastric cancer among all gastric cancers has been and will be more increased in Korea.

Pityriasis rosea is sometimes accompanied with considerable pruritus. Ultraviolet B irradiation is reported to be beneficial in relieving pruritus. The purpose was to evaluate the effect of UVB phototherapy on severe pruritus of pityriasis rosea. Nine patients with severe pruritus had UVB irradiation three times a week Five patients became symptom free and three showed a marked improvement. One dropped out. UVB phototherapy could be an effective modality for relieving pruritus in pityriasis rosea.

In order to search for anti-Herpes simplex virus (HSV) type-1 agents from Korean medicinal herbs and Korean traditional prescriptions (herb complexes), we selected 80 medicinal herbs and 45 prescriptions, based on a review of the Korean traditional medicine books. Both methanol extracts and boiling-water extracts were tested by means of the MTT assay (tetrazolium based colorimetric assay). Ten of the 125 methanol extracts: CM-11, CM-18, CM-19, CM-21, CM-22, CM-39, MM-3, MM-18, MM-29, MM-73 (see explanation of nomenclature below), showed efficacy against HSV-1. Twelve of the water extracts: CW-2, CW-3-I, CW-3-II, CW-18, MW-3, MW-5 MW-6, MW-12, MW-47, MW-69, MW-73 and MW-75 were active. #3 (individual herb) and #73 (individual herb) were interesting because both water and methanol extracts were active. Especially, #3 is a part of composition of Hong-il-laksamd ngbang and Hojanghaedokt'ang which have anti-HSV-1 activitives. The SI value of MW-69 and CW-18 was relative high as 10.2+/-0.7 and 11.8+/-2.2. The cytotoxic effect on Vero cells of Panch' n-ch' ngbang, Taraxacum platycarpum H. Dahlst. and acycloguanosine was determined by MTT assay. Water extracts of Panch' ngch' ngbang (prescription) and Taraxacum platycarpum H. Dahlst. showed very weak cytotoxic effects on Vero cells at > 100 mug/ml but acycloguanosine showed strong cytotoxic effects on Vero cells at > 100 mu g/ml. As a result, #3, #73, MW-69 and CW-18 are considered as potentially useful for anti-HSV-1 agent and will be the focus of further research. Abbreviations: CM - methanol extracts of traditional prescriptions; CW - water extracts of traditional prescriptions; MM - methanol extracts of individual herbs; MW - water extracts of individual herbs.

Ubiquitin-positive neuritic threads (UNTS) in the hippocampal CA 2-3 region are reported to occur exclusively in association with so-called diffuse Lewy body disease (DLBD). hi order to assess the association between the occurrence of Lewy bodies (LBs) and that of the UNTs, an immunohistochemical study on the hippocampus including the parahippocampal gyrus with antiubiquitin antibody (Chemicon Co., California, U.S.A.) was perfon-ned in four groups of patient's brains. All brains were selected from the large pool of brains referred to the Neuropadiology Laboratory of the University of Minnesota for studies of Alzheimer's disease. Group 1 consisted of 34 cases (20 male and 14 female) with LBs widespread in the frontal and temporal cortex and the brain stem nuclei (basal nucleus, substantia nigra, locus ceruleus and dorsal vagal nucleus) associated with varying degrees of degeneration of the substantia nigra; 21 (11 male and 10 female) combined with and 13 (9 male and 4 female) without Alzheimer's disease (AD) pathology. Group 2 included 12 cases (9 male and 3 female) in which LBs were observed only in the brain stem nuclei; 7 with and 4 without AD pathology. Group 3 consisted of 30 cases (9 male and 21 female) without LBs but with AD pathology and degeneration of the substantia nigra. Group 4 included 23 cases (11 male and 12 female) with neither LBs nor AD pathology but with degeneration of the substantia nigra. Ages of the patients varied among the groups. In the 46 cases in the first two groups with LBs. The mean age in the 28 cases with AD pathology was 77.3+/-8.9 and in the 18 cases without AD pathology it was 71.6+/-8.8 (P<0.05). In the 53 cases in groups 3 and 4 without LBs, which served as the controls, the mean ages were 80.8+/-7.7 and 74.0+/-9.7 respectively. UNTs were encountered in all (100%) of 34 cases of group I with widespread LBs which met the histological criteria of DLBD regardless of combined AD pathology. In 12 cases of group 2 with LBs confined to the brain stem, UNTs occurred in 3 (25%), 1 with and 2 without AD pathology. hi the group 3 cases with only AD pathology, UNTs occurred in 4 (13%) of 30 cases, while no UNTs were encountered in the 23 cases of group 4 without AD pathology or LBs. In conclusion, UNTs in the hippocampal CA 2-3 region occur invariably but not exclusively in association with widespread LBs, frequently when LBs are confined to the brain stem, and infrequently with AD pathology. It seems, therefore, that the UNTs are closely related to LBs and increase in ftequency as LBs spread beyond the brain stem with time, but the pathogenesis of the UNTs is little understood.

This study was conducted to investigate the effect of two-year course of food and nutrition on improving nutrition knowledge, dietary attitudes and food habits of junior college female students by questionnaires. The subjects were 108 college female students enrolled in the department of food and nutrition in Gyeonggi area. The results were as follows: There were no significant changes in the weights and BMI (Body Mass Index) after 2-yr course of food and nutrition. Nutrition knowledge (14.7 vs 16.3, p < 0.001) and dietary attitude (34.3 vs 35.8, p < 0.01) increased significantly after 2-yr course. However, no significant changes in food habit were observed. Among nutrition knowledge, the scores of functions (4.5 vs 5.2, p < 0.001) and understanding (6.7 vs 7.4, p < 0.01) of nutrients were significantly increased. The recognition of nutrition knowledge increased significantly (83.1 vs 95.7, p < 0.001). Among food habit, dietary habit (13.2 vs 12.5, p < 0.01) and health related habit (15.6 vs 14.6, p < 0.001) were significantly lowered after 2-yr course. The change in dietary attitudes showed significantly positive correlation with food habit changes (p < 0.05). These results showed that 2-yr course of Food and Nutrition had improved the nutrition knowledge and dietary attitudes. Therefore, providing the more systematic and appropriate nutrition education to students during their study period will be improved dietary attitudes and food habits.

Cervical tuberculous lymphadenitis is a commonly encountered disease, expecially in adults, Differentiation from other lymphadenopathy and benign conditions such as cystic neck masses is important. CT findings of tuberculous lymphadenopathy in the abdomen and thorax are reported in many literatures. But there are only a few articles concerning cervical tuberculous lymphadenopathy. The authors retrospectively analyzed CT findings of 33 cases with cervical tuberculous lymphadenitis regarding distribution, contour, enhancing pattern, changes of adjacent fascial plane, and dermal and subcutaneous manifestations. We concluded that the presence of conglomerated nodal masses with central lucency, thick irregular rim of contrast enhancement and inner nodularity, varying degree of homogenous enhancement in smaller nodes, dermal and subcutaneous manifestations of inflammation such as thickening of overlying skin, engorgement of the lymphatic and thickening of adjacent muscles, and diffusely effaced fascial plane are suggestive of tuberculous lymphadenitis. However, some CT patterns of tuberculous adenitis may be seen in other disease; for example, enhancement can occur in hyperplastic nodes, vascular metastasis(thyroid, melanoma, and hypernephroma), lymphoma, granulomatous disease, and Castleman's disease.

Steroid cell tumor of ovary, first described as lipid cell tumor, is rare lesions composed entirely of cells resembling typical steroid hormone - secreting cells, that is lutein cells, Leydig cells, and adrenal cortical cells. Steroid cell tumors oftcn secret androgen and manifest themselves with symptoms of virilization. Other presentations include abdominal swelling or pain, menstrual dysfunction, postmenopausal bleeding, or rarely ascites. We experienced a case of right ovarian steroid cell tumor, not otherwise specified(NOS), manifested hirsuitism and amenorrhea in 49 - year - old patient. The tumor was about 5 cm in size, and associated with huge ascites (l3,000 ml), both pleural effusion, and elevated serum CA 125. We present a case of Meigs syndrome associated with benign ovarian steroid cell tumor with a brief review of the literature.

We developed an animal model to recreate the condition of an open fracture in communication with the maxillary sinus. We then studied wound healing of the sinus wall structures following fracture in the presence of autogenous bone and alloplastic implant. This model is designed to simulate the repair of an orbital floor fracture in humans. The New Zealand White rabbit was used as the animal model. Standardized 8mm defects were made bilaterally in the maxillary sinuses to include bone and mucosa in 36 rabbits. Two different implants and autogenous calvarial bone graft were placed in the soft-tissue pockets to obturate the defects, exposing one surface of the implant to the open sinus. Medpor porous polyethylene, silicone and calvarial bone implant were compared. Animals were killed at 1, 2 and 8 weeks after implantation. Gross examination of the specimens for the amount of mucosal closure and implant tissue fixation was performed. Histological sections were evaluated for bone and soft-tissue morphology juxtaposed to the implant. Complete closure of the mucosal defect was demonstrated with each type of implant. Medpor implants showed both vascular and soft-tissue ingrowth into pores by week 1. Bone ingrowth was seen by week 2. Closure of the Medpor obturated defects occurred more rapidly than in the silicone group. The Medpor implants and calvarial bone demonstrated bone and soft-tissue fixation, callus formation and maturation, while mature overlying mucosa was reconstituted over the defects. Silicone implants demonstrated a fibrous tissue reaction within 1 week of implantation and they never became fixed to bone or soft tissue. Maxillary sinus wall regeneration occurred in all defects. This study supports clinical observations of maxillary sinus wall regeneration in humans.
