PURPOSE: recent studies have reported that the expression of Drg-1 is up-regulated by androgen. It has been suggested that Drg-1 gene be used as a molecular marker for prostate cancer therapies like PSA. To de termine the role of Drg-1 gene as a molecular marker during intermittent androgen deprivation(IAD) therapy, we investigated the expression of Drg-1 and compared it with PSA expression in human prostate cancer cell lines treated with dihydrotestosterone (DHT) continuously or intermittently. MATERIALS AND METHODS: Two prostate cancer cells having different status of androgen receptor [LNCaP (androgen dependent) and PC-3 (androgen independent)] were used in this study. To know the change in PSA and Drg-1 expression after DHT treatment the cells were cultured in steroid-free RPMI media for 24 hours. 10(-7) and 10(-8)M of DHT and 10(-7)M bicalutimide was added into the cells and then cultured for 72 hours. And we established in vitro IAD model using LNCaP cells. Northern analyses were performed to determine the expression level of both PSA and Drg-1genes. Also, western analyses were performed to determine the protein level of proliferating cellular nuclear antigen and androgen receptor. RESULTS: Transcripts of Drg-1 were detected in both LNCaP and PC-3 cells but PSA was not expressed in PC-3 cells. The expression of Drg-1gene in LNCaP cells was up-regulated by 10(-8)M of DHT like PSA gene and down-regulated by 10(-7)M bicalutamide. In the treatment of intermittent androgen deprivation, the expression pattern of Drg-1was similar to that of PSA. However, up-regulation of PSA was detected earlier than of Drg-1. CONCLUSIONS: Based on observation, Drg-1 was up-regulated by androgen and down-regulated by anti-androgen. This suggests that Drg-1gene is useful for determining the androgen independency of prostate cancer during IAD.

OBJECTIVE: The aim was to assess the value of resistance index(RI) and pulsatility index(PI) to differentiate between benign and malignant ovarian tumors by color and pulsed Doppler ultrasound. METHODS: 129 ovarian tumors identified with ultrasound were referred for color and pulsed Doppler ultrasound evaluation to calculate the lowest RI and PI, and the corresponding histopathologic diagnosis was recorded. RESULTS: The intratumor artery waveforms were obtained in 37.1%(36 of 97) of benign tumors and in 91.0%(29 of 32) of the malignant group. RI and PI were lower in malignant tumors than in benign tumors(p<0.01). Also, there was a significant incremental decrease in both indices value from the benign tumor toward borderline malignancy(p<0.05) and to invasive ovarian cancer(p<0.01). But, there was no significant difference in both indices value according to the FIGO stage of ovarian malignancy. For RI cut-off value of 0.6, sensitivity and specificity were 89.7% and 91.7%; for PI cut-off value of 1.1, 86.2% and 91.7%. Therefore, the most accurate cut-off values of RI and PI were 0.6 and 1.1, respectively. CONCLUSION: RI and PI calculated by color and pulsed Doppler ultrasound can help in the diagnosis and selection of treatment plan of ovarian tumors, especially when the morphological finding of ovarian tumor is equivocal. And during the follow up of benign tumors, both indicies can give us the clue of malignant potential of benign tumors.

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.

Gastrocelic fistula of malignant origin is a rare complication, usually due to gastric or colon cancer. Possible other etiologic factors resulting in gastrocolic fistula are peptic ulcer, trauma, carcinoid tumor, intestinal tuberculosis, Crohn's disease, lymphoma, intraabdominal abscess, diverticulitis and etc. At the present, earlier diagnosis and treatment of gastric and colon cancer may explain the low frequency of malignant gastrocolic fistula than the past but the review of Korean literatures revealed only two reports of gastrocolic fistula secondary to gastric cancer and another from benign gastric ulcer. Yet, there has been no report of fistula due to colon cancer. We experienced a case of colon cancer with postural dizziness, fecal eructation who was diagnosed as gastrocolic fistula by endoscopy, barium enema, UGI series and finally underwent operation. Therefore, we report this case with the review of literatures.

Gastrocolic fistula is a rare lesion which is caused most commonly by carcinoma of colon or stomach. The less common causes of gastrocolic fistula are follows: trauma, faulty gastrocolic anastomosis during gastrectomy, benign gastric ulcer, syphilis, carcinoid tumor, tuberculosis, intraperitoneal abscess, lymphoma, perforated diverticulum of colon, and ulcerative colitis. The locations of fistulae are mostly between greater curvature of stomach and distal half of the transverse colon. In the case of penetrating benign gastric ulcer and gastrcolic fistula, it is usually associated either with asipirin or with prolonged steroid administration. A 36-year-old male who had an unusual gastrocolic fistula secondary to non-surgically treated benign gastric ulcer is presented. The exitence of a gastrocolic fistula was dernonstrated by radiological examination of the colon and the stomach. In this patient, the colonoscope passde through the fistula and the stomach could be examined. Careful preparation was carried out preoperatively with intravenous fluids and blood transfusions. Resection of the distal stomch, fistulous tract, and segment of the transverse colon was then accamplished.

ERCP may provide more definite diagnosis, preoperative guidance, and endoscopic therapy in many children with known and suspected disorders of the pancreas or biliary tract. To our knowledge, there has been rare case of ERCP in children and no reported case of ERCP performed in inf~int less than 2 years old in Korea. We report a case of KRCP performed in 26 month old girl who was admitted to evaluate jaundice. We diagnosed CBD stones and choledochal cyst, Todani type III containiaig stones by ERCP. After endoscopic sphincterotomy(EST), removal of stones, and endoscopic nasobiliary drainage(END) her bilirubin level normalized about 2 months later.

BACKGROUND/AIMS: Paracentesis is an acceptable therapeutic modality for the symptomatic relief of dyspnea or abdominal fullness due to tense ascites in patients with cirrhosis. Whereas studies about the effects of paracentesis focused on the changes about hemodynamics, electrolytes and renal function in great detail, the effects of paracentesis on the changes about respiratory system have undergone limited investigations which are defined large-volume paracentesis. METHODS: We performed pulmonary function tests with arterial blood gas analysis just before and 24 hr after paracentesis. The paracentesis of average 2,300ml was carried out in ten liver cirrhosis patients with tense ascites who were free from underlying cardiopulmonary impairment. RESULTS: 1. The results of pulmonary function test just before paracentesis were as followings; FVC( functional vital capacity), FEV1(forced expiratory volume in 1 sec), FEF25 75(forced expiratory effort 25% 75%) and TLC(total lung capacity) were decreased as 78%, 79%, 62.3% and 89% of normal control value respectively, whereas RV(residual volume) was not decreased. DLCO(lung diffusion capacity of carbon monoxide)was decreased as 61.6%. 2. The results of pulmona function test 24 hr after paracentesis were as followings,' The symptomatic relief of dyspnea was achieved in all participated ten patients. Among lung volume parameters, FVC and VC were increased significantly(p=0.003, p=0.004). Whereas TLC was increased without statistical significance(p=0.228), and RV and FRC(functional residual capacity) showed no change. FEV1 was increased significantly(p=0.039), but FEF25 75 and the ratio of FEF1/FVC showed no change. DLCO was not increased. PaOy(partial pressure of oxygen in arterial blood) was impr'oved without statistical significance. CONCLUSIONS: These results suggest that the patients of liver cirrhosis with ascites have restrictive ventilatory impairment with additional obstructive ventilatory impairment. After paracentesis, the restrictive ventilatop impairment is improved by the relief of diaphragmatic motion limitation caused by ascites. Also, paracentesis of(not large volume, like 5000ml, but) relatively small volume, of 2000 3000ml can achieve objective improvement of dyspnea due to tense ascites.
