Superficial gastritis has been classified as a type of chronic gastritis, since a report of Schindler in GASTRLTIS, 1947. Howev~er, Benedict reported that superficial gastritis is only acute gastritis or shows normal mucosa histologically. The com mon endopical findings of chronic superficial gastritis were adherent mucus, edema, redness. The common redness which were encounterd are patchy redness and comb-like redness(Kammrotung). We studied the relationship between the redness of superficial gastritis and acute inflammatory changes histologically. Each case of superfieial gastritis was biopsied to redening and non-redening mucosa respectively. We collected 24 cases with 48 biopsy specimens. The results are as follows: Acute inflammatory changes were found only one case in redness and none in non-redness groups. There was no difference in acute inflammatory changes in two groups. The degree of mucosal atrophy were 62.5%, 66.7% in normal mucosa, 12.5%, 16.7~% in mild atrophy, 25%, 12.5% in moderate atrophy, 0%, 4.l% in severe atrophy with respect to redness and non-redness mucosa respectively. There was no difference in degree of mucosal atrophy in two groups. Mucosal atrophies were higher in older ages above 41 years old than below 40 and with increasing age, there was increasing tendency of mucosal atrophy. In conclusion, There was no relationships between mucosal redness and acute in flammatory changes histologically and also between mucosal redness and degree of atrophy.

Patients with inflammatory bowel disease are known to have hypercoagulability and an increased risk for venous thromboembolism. The deep veins of the lower extremities and the pulmonary veins are the most common sites of thrombosis in ulcerative colitis. However, hepatic vein thrombosis (Budd-Chiari syndrome) is a very rare extra-intestinal complication of ulcerative colitis in children. We describe a case of hepatic vein thrombosis in a 15-year-old girl with ulcerative colitis who presented with abdominal pain and hematochezia. Doppler ultrasonography and an abdominal CT scan revealed the characteristic filling defects caused by large thrombi in both hepatic veins. These lesions were successfully treated with conventional management for ulcerative colitis and anticoagulation therapy.

PURPOSE: This study was designed to find out whether protein kinase C (PKC) may affect telomerase activity in human ovarian cancers. MATERIALS AND METHODS: To determine whether PKC modulators influence PKC activities, NIH: OVCAR-3 and CUMO-2, cells were treated with PKC inhibitors, G 6976 and bisindolyl maleimide I, and PKC activator, 12-O-tetradecanoyl phorbol 13-acetate (TPA). Telomerase acti vity was determined by telomeric repeat amplification protocol (TRAP). Analysis of the expres sion of each telomerase subunits, human telomerase RNA (hTR) and human telomerase reverse transcriptase (hTERT), was performed by RT-PCR. We also examined the alternative splicing of hTERT. RESULTS: G 6976 and bisindolylmaleimide I inhibited PKC activity. Telomerase activities appeared to be affected in a time-dependent manner by these two PKC inhibitors. PKC activities were increased in parallel with telomerase activity by TPA at the low dose (10 nM), but their activities were down-regulated at the high dose (1 micrometer). RT-PCR demonstrated the presence of hTR and hTERT mRNA before and after the treatment of PKC modulators, respectively, and showed the presence of one alternatively spliced transcript and full-length hTERT transcripts. CONCLUSION: These results showed that telomerase activity was affected by PKC and suggested PKC modulation may serve as an useful tool in the regulation of telomerase activity.

OBJECTIVE: The aim of this study was to investigate the 3-dimensional position of the center of resistance of the 4 maxillary anterior teeth, 6 maxillary anterior teeth, and the full maxillary dentition using 3-dimensional finite element analysis. METHODS: Finite element models included the whole upper dentition, periodontal ligament, and alveolar bone. The crowns of the teeth in each group were fixed with buccal and lingual arch wires and lingual splint wires to minimize individual tooth movement and to evenly disperse the forces to the teeth. A force of 100 g or 200 g was applied to the wire beam extended from the incisal edge of the upper central incisor, and displacement of teeth was evaluated. The center of resistance was defined as the point where the applied force induced parallel movement. RESULTS: The results of study showed that the center of resistance of the 4 maxillary anterior teeth group, the 6 maxillary anterior teeth group, and the full maxillary dentition group were at 13.5 mm apical and 12.0 mm posterior, 13.5 mm apical and 14.0 mm posterior, and 11.0 mm apical and 26.5 mm posterior to the incisal edge of the upper central incisor, respectively. CONCLUSIONS: It is thought that the results from this finite element models will improve the efficiency of orthodontic treatment.

Intestinal tuberculosis has been known since antiquity. After about 1950's, effective antituberculous chemotherapy and an improved standard of living resulted in a steady decline in all forms of tuberculosis. However, intestinal tuberculosis has been reported with impressive frequency in developing countries including Korea. Disease affecting the duodenum is reported to be rare and isolated duodenal tuberculosis sparing the rest of the intestine is uncommon. We experienced a case of tuberculosis of duodenal bulb associated pulmonary tuberculosis. The diagnosis was made on the basis of the histological study of the endoscopic biopsy specimen. We have confirmed the healing of the duodenal lesion by the follow-up endoscopy after 9 months treatment of antituberculous medication.

Malarial infection is one of the most important tropical diseases, but also increasing in the temperate regions. Severe malaria with organ dysfunction is commonly associated with Plasmodium falciparum, but rarely with Plasmodium vivax. Malarial hepatitis is also unusual in P. falciparum and very rare in P. vivax. Only 3 cases of malarial hepatitis caused by P. vivax have been reported in the world. Because the presence of hepatitis in malaria indicates a more severe illness with higher incidence of other complications and poor prognosis, malarial patients should be meticulously monitored for hepatic dysfunction with or without jaundice. We report here a case of malarial hepatitis caused by P. vivax that was presented by fever, general ache, nausea, fatigue, and significant elevation of aminotransferase and bilirubin.

Moyamoya is a chronic cerebrovascular disease characterized by progressive stenosis or occlusion of the terminal parts of both intermal carotid arteries with telangiectatic vascular network of collateral circulation at the base of the brain and leptomeningeal arteries. The etiology and pathophysiology of this disease are still unknown. Although the idiopathic presentattion is the commonest, moyamoya disease has also been reported in several hereditary or acquired clinical conditions including neurofibromatosis, sickle cell anemia, tuberculous meningitis, atherosclerosis, and following radiation therapy to the head. The term moyamoya disease should be reserved for those cases in which the characteristic angiogrphic pattern is idiopathic; moyamoya syndrome is used when the underlying condition is known. We have experienced a case of coexistence of moyamoya syndrome and hereditary spherocytosis in a 6-year-8-month-old girl who presented with right-sided hemiparesis and pallor. A cerebral angiogram revealed occlusion of proximal portion of left middle cerebral artery and abnormal collateral network. The peripheral blood smear and osmotic fragility test disclosed hereditary spherocytosis. To our knowledge, the coexistence of moyamoya syndrome and hereditary spherocytosis has not been documented. We report here the case and the brief review of related literatures. Further studies are needed to clarify the intimate relationship between the two diseases.

PURPOSE: Many reliable articles on the effectiveness of alpha blockers have been published. Evidence-based diagnostic guidelines and therapeutic guidelines for benign prostatic hypertrophy (BPH), which is one of the most common urological diseases, have been proposed in many foreign countries. This paper examines the efficacy of alpha blocker, a common therapeutic drug for BPH, in Korean patients through meta-analysis. MATERIALS AND METHODS: From 1993 to 2001, the term 'BPH' and alpha blocker for BPH were used as key words to search for related articles in the Medical Research Information Center, the National Assembly Library of the Republic of Korea, the Korean Journal of Andrology and the Korean Journal of Urology. A total of 10 articles were selected as being suitable for evaluation and these articles were ranked with levels ranging from I to V, where level I indicated a large randomized controlled trial and level V indicated a non-controlled case accumulation study. RESULTS: There were improvements for the symptom score (45.3%), and for the maximum urinary flow rate (36.0%). The reasons for patient drop-outs were follow-up loss for 60%, drug side effects for 11%, and ineffectiveness of drug for 6.8%. The common side effects were dizziness (4.2%), orthostatic hypotension (2.2%), and headache (1.7%). The blood pressure was sustained in the normotensive patients, wheareas BP showed a tendency to be reduced in hypertensive patients. CONCLUSIONS: Treatment with alpha blocker resulted in the BPH patients in all the studies receiving sustained benefit. Yet most of these papers were short-term, non randomized case-accumulation studies. However, BPH is a chronic disease that may worsen over time. Therefore, evaluation of long term tolerability and efficacy of alpha blocker is necessary.

Double primary cancer means that more than two cancers with different origin exist independently in an individual. The diagnosis of double primary cancer was determined by following criteria. Each of the tumors must present a definite picture of malignancy, and each must be distinct, and the probability of one being a metastasis of the other must be excluded. Small cell carcinoma has a distinct biological behavior such as, early invasion and metastasis, a rapid clinical course, and significant sensitivity to chemotherapy. Small cell carcinoma in the esophagus is relatively rare, and rarer when it is combined with other malignant disease. We have experienced a case of double primary cancer, a 70-year-old man with esophageal small cell carcinoma and gastric adenocarcinoma, which were diagnosed by gastrointestinal endoscopic biopsy. A review of the Korean medical literature failed to reveal any previously described case of esophageal small cell carcinoma with gastric adenocareinoma. We report this case with review of literatures.
