Objectives: Endoscopic variceal ligation is well established metbod of treatment for esophageal varices whereas for gastric varices there has not been any systematic report of its use as a method of treatment. To evaluated its possible clinical application, the band ligation(banding) and the method of band ligation in conjuction with submucosal ethanolamine injection(banding with sclero) were tested on canine stomach, and results were assessed.

Lymphoepithelioma-like carcinoma (LELC) that histologically resembles nasopharyngeal lymphoepithelioma has been reported in various sites including the stomach, salivary gland, lung, skin, thymus, tonsil and uterine cervix. LELC of the stomach was rarely reported after the first report by Burke et al. in 1990. More than 60% of them were associated with Epstein-Barr virus (EBV). Most commonly affecting elderly Asians with slight male predominance (M/F ; 1.2/1), it usually is located in the proximal portion of the stomach and distinguished from lymphoid-rich adenocarcinoma by the absence of definitive glandular differentiation in the LELC. We recently experienced 4 cases of LELC of the stomach associated with EBV. Patients consisted of two Korean females and two Korean males with one in 3rd decade, one in 5th decade and two in 6th decade. The tumors of all cases were located in the proximal portion of the stomach. Gross types were 1 Borrman type I, 2 Borrman type II and 1 early gastric carcinoma type IIc. The size of the tumors varied from 0.8 cm to 7 cm. Microscopic findings were similar in all 4 tumors.; The tumors were composed of syncytial nests of undifferentiated cells having vesicular nuclei with prominent nucleoli, admixed with abundant lymphoplasma cell infiltration in the stroma. Immunohistochemical staining revealed that the tumor cells were reactive for cytokeratin and the stromal lymphocytes were mostly T cells. There were dark hybridization signals in the nuclei of most of the tumor cells but no signals in the stromal lymphocytes in three cases on in situ PCR hybridization and on all cases PCR amplification for EBNA-1. It is concluded that LELCs of the stomach have distinctive histologic characteristics and the usual association with EBV. Further accumulation of these cases will define the prognosis.

We have recently experienced a case of prune-belly syndrome, in 119/12-year-old male child with congenital defects of abdominal muscles, cryptorchidism, hydronephrosis, megacystis and spina bifida. Diagnosis was confirmed by EMG, IVP, retrograde cystogram, radiorenogram & renal scanning, and roentgenologic examinations. The patient in this report may be one of the most long-term survival case reported in korean literature.

Juvenile polyp of the large intestine is the most common polyp among children and has no malignant potential. We experienced a case of 3-year old male who presented with rectal bleeding and polyp. The polyp was spontaneously resected and the size was 35 50 10 mm. Pathologically, the polyp was consistent with juvenile polyp of the rectum.

Tuberculosis of the penis is an extremely rare disease. In 1878 Fournier reported the first case and up to 1971 only 139 cases had been reported. In Korea there were some cases but no report was made in the era of antituberculous drugs. We report a case of tuberculosis of the penis and review the literature briefly.

Bony fixation of implants during the early phase of healing is important in order to get secondary stability of the implant assuring the success of the treatment. Because the successful placement of the implant is limited by the quality and quantity of bone, other agents which stimulate bone formation in the peri-implant spaces has been illustrated. Platelet-derived growth factor (PDGF) has been shown to regulate DNA and protein synthesis in bone cells in vitro and to interact synergistically to enhance soft tissue wound healing in vivo. The purpose of this study was to evaluate bone promotion around implants which were augmented with sagittal split osteotomy or autogenous veneer bone graft using the platelet derived growth factor(PDGF). After placement of newly designed twenty four screw-type implants, which were 12mm in length and 4mm in diameter in 6 dogs. 4microgram of PDGF B/B was applied with surgicel carriers. The dogs were sacrificed at 3 days, 1, 2, 3, 6, and 12 weeks after implantation. Specimens were examined clinically, radiographically, histologically, and histomorphometrically. The results were as follows: 1. Clinically and radiologically, there was no significant difference in bone formation and healing pattern between experimental and control group. 2. In autogenous veneer bone graft group, bone formation was observed at 1st week in the experimental groups but 2nd week in the control groups. At 3rd week, the expeimental groups showed more bone formation comparing to the control groups. 3. In sagittal split osteotomy group, bone formation was observed at 1st week in both groups. But the experimental groups showed more bone formation comparing to the control groups after 2nd week. 4. The bone growth rate of experimental group was more rapid than that of control group. These results indicated that PDGF did not affect the initiation of new bone formation, but it accelerated the bone formation at the early period.

The authors studied the expression of proliferating cell nuclear antigen (PCNA) and the number of argyrophilic nucleolar organizer regions (AgNORs) in 94 cases of various brain tumors and in 5 cases of normal brains. PCN was recognized immunohistochemically in paraffin sections by the monoclonal antibody PC-10. AgNORs could be demonstrated using the silver impregnation method. The PCNA index was not significantly different from the histological grading of glioma(glioblastoma multiforme: 41.40+/-29.14%, anaplastic astrocytoma: 35.00+/-41.02%, and low grade astrocytoma: 22.37+/-30.85%) and there was a wide range of staining even in the same tissue section. However, the AgNORs count per cell correlated well with the pathologic grading of glioma (glioblastoma multiforme : 3.19+/-0.71, anaplastic astrocytoma : 2.06+/-0.16, and low grade astrocytoma : 1.27+/-0.29) with statistical significance. In meningiomas, AgNORs were useful to differentiate benign meningiomas(1.25+/-0.19) and malignant meningiomas(1.78+/-0.35) The authors suggest that the AgNORs count is a faster, less expensive, and a more predictive method in the malignancy of brain tumors than the PCNA immunochemistry expression.

Several growth factors and polypeptides were studied for the regeneration of periodontal supporting tissues which had been lost due to periodontal disease. But these are not commonly used for regenerators of bone tissue or alveolar bone, because of the insufficiency of studies on their side effects, genetic engineering for mass production and stability for clinical application. Recently, many natural products, which have advantage of less side effects and possibility of long-term use, have been studied for their capacity and effects of anti-bacterial, anti-inflammatory and regenerative potential of periodontal tissues. Cnidii Rhizoma, Rhinocerotis Cornu and Drynariae Rhizoma have been traditionally used as a drug for treatment of bone disease in oriental medicine. The purpose of this study was to examine the ability of alkaline phosphatase synthesis of MC3T3-E1 cells when above medicines were supplimented. MC3T3-E1 cells were cultured with alpha-MEM(negative control), dexamethasone(positive control), and each natural products for 3 and 5 days. And then ALP synthesis was measured by spectrophotometer for enzyme activity and by naphthol AS-BI staining for morphometry. Except Cnidii Rhizoma, all of the natural products of this study induced higher activity of ALP synthesis than controls. Among them Drynariae Rhizoma induced the highest activity. In the aspects of culturing time, all medicines did not showed the difference between 3 and 5 days, but 10-7g/ml group of Rhinocerotis Cornu showed significant increase at 3 days than at 5 days. These results indicate that several natural products have a inducing ability of ALP synthesis on osteoblasts.
