우리나라에서 인기 있는 게장등의 섭취로2) 성인뿐만 아니라 소아에서도 지속적으로 보고되고 있는 폐흡충증은 다양한 임상양상을 보일 수 있다. 저자들은 방사선 소견상 만성 호산구성 폐렴과 유사하였고, 반복적인 치료로 호전된 폐흡충증 1예를 경험하였기에 보고하는 바이다. Paragonimiasis mostly occurs by ingestion of raw or undercooked freshwater crabs or crayfish. Recently, re-emergence of paragonimiasis is reported because of ingestion of raw food such as freshwater fish and Gejang (marinated raw crabs). As the radiological features as well as the laboratory findings are similar to those of chronic eosinophilic pneumonia, the diagnosis of pulmonary paragonimiasis is often difficult and delayed. A 43 year-old female was visited our hospital for migrating and new developing consolidative lung lesions and peripheral blood eosinophilia. The eosinophil profile of leukocyte was 32% (absolute count 2,690 /mm3). Histologic finding was organizing pneumonia pattern with severe infiltration of eosinophils. Parasite specific antibody IgG forParagonimus westermani was positive (titer:0.61, normal range<0.20). After treatment with praziquantel (75mg/Kg once a day for 2days), the chest x-ray was clearly resolved. Follow-up study showed right pleural effusion, newly developed focal infiltration, and several nodules. After retreatment, we couldn't find any recurrent evidence.

천영국,김영태,홍수진,김진오,조주영,이문성,심찬섭 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.1
Background/Aim: It is difficult to dignosis of Borrmann type 4 gastric cancer at the early stage, because of its special morphology. Most of the cases have been detected at the advanced stage with poor survival rate. We reviewed patients with advanced gastric cancer, to define clinicopathologic characteristics of Borrmann type 4 gastric cancer comparing other types of gastric cancer. Methods: 1033 patients with advanced gastric cancer were divided into two groups, consisting of 50 patients with Borrmann type 4 gastric cancer, and the remaining 983 patients with all other types of gastric cancer, which were then compared clinicopatologically. Results: The proportion of Borrmann type 4 gastric cancer to advanced gastric cancer was 4.48%(50/1,033). The patients with Borrmann type 4 gastric cancer to advanced gastric cancer was 4.48%(50/1,033). The patients with Borrmann type 4 gastric cancer were composed 20 males and 30 males and revealed the highest frequency 3rd decade (24.0%) in age (range 26-78). In giant folds group (n=27), the number of poorly differentiated cell type, lymph node metastasis, peritoneal seeding were 20 (74.1%), 17 (63,0%), 12 (44.4%). In non-giant folds group (n=23), the number of poorly differentiated type, lymph node metastasis, peritoneal seeding were 17 (73.9%), 15 (65.2%), 6 (26.1%). Rate of tumor invasion in serosa and beyound serosa was 88.9% in giant fold group, 63.0% in non-giant fold group. Surgery was performed in only 32% as a modality of treatment (vs. 82.5%). Characteristics findings of Borrmann type 4 gastric cancer in EUS showed a thickening of the third (submucosa) and fourth (muscularis propria) layers in 72% of 50 patients, and a well preserved five-layered gastric wall structure in 33 patients. Conclusions: We concluded that Borrmann type 4 gastric cancer was diagnosed more in females, as a more advanced disease, early detection was needed. And endoscopic ultrasonography is useful for diagnosis of Borrmann type 4 gastric cancer in the cases of suspicious results of gastroscopy.

연폭로 근로자들에서 적혈구 Pyrimidine 5'-Nucleotidase 활성도 및 요중 N-Acetyl-β-D-Glucosaminidase 활성도와의 상관관계 연구
서홍규,이병국,황천현,장성훈,이성수,이원진,최재욱 大韓産業醫學會 1997 대한직업환경의학회지 Vol.9 No.2
In this study, we measured the activity of the erythrocyte pyrimidin 5'-nuclectidase(P5N) and urinary N-acetyl-β-D-glucosaminidase(NAG) from 154 workers exposed to lead and 43 workers not exposed. We analyzed the correlation of the P5N activity and NAG activity with other biololgical exposure indices of lead such as blood lead(PbB) and zinc protoporphyrin(ZPP). The measurement was performed by using high performance liquid chromatography(HPLC), spectrophotometer and atomic absorption spectrophotometer. The results are as follows : 1. The mean value of P5N activity for workers exposed to lead was 9.50±3.13 μmol uridine/hr/g Hb and 11.60±2.2 μmol uridine/hr/g Hb for workers not exposed. The P5N activity showed a normal distribution, but the other indices of lead showed logarithmic normal distributions. 2. The P5N activity and ZPP were decreased as PbB was increased. But the NAG activity had no correlation with changes of PbB. 3. The correlation coefficients of the P5N activity with other biological exposure indices of lead such as PbB, ZPP, NAG activity were -0.72, -0.55, and 0.05, respectively. We speculated that the P5N activity can be used as a reliable biological exposure index of lead but NAG activity can be used as a biological management index of lead.

이기철,이정호,김진규,정홍경,천강훈,류정환,최영민,전성일 대한생물치료정신의학회 1998 생물치료정신의학 Vol.4 No.2
Objectives : Recently, some case reports have shown that risperidone is effective to refractory obsessive-compulsive disorder. Possible explanations for efficacy of risperidone in refractory obsessive-compulsive disorder maybe due to that it is both serolonin and dopamine receptor antagonist. On the basis of serotonin-dopamine interaction hypothesis, a biological etiology of obsessive-compulsive disorder, the effect of risperidone was evaluated to the suppressed spontaneous alternation behaviour of animal model of obsessive-compulsive disorder in rats. Methods : The apparatus for spontaneous alternation behaviour was a black plexiglas T-maze with distinctive black and white goal boxes. Black gullotine doors separated the start box and the goal boxes from the main body of the T-maze Small cups were placed in the corners of both goal boxes(all arms measured 50×10cm) 24 hours prior to experiment, rats(Spraque-Dawley) were food-deprived. The food-deprived rats were put into T-maze, in which both goal boxes were baited with small amounts of chocolate milk. Each rat was given 2 set of 7 trials during which it was placed in the start box and allowed to choose the one of the goal boxes for checked. After baseline of the number of choices of spontaneous alternation behaviour was stabilized, the pontaneous alternation disrupted by nonselective 5-HT agonist, 5-MeODMT (1.25mg/kg/IP). The experimental animals were stratified into 5 groups, fluoxetine(10mg/kg/IP), risperidone(0.1mg/Kg/IP), haloperidol(0.1㎎/Kg/IP), fluoxetine(10mg/Kg) with haloperidol(0.1 mg/Kg), and saline(0.5cc/IP) control group. Each drugs were injected for 21 days as a chronic treatment. The protective effects were evaluated on the nest day of discontinuation of the each drugs among 5 groups. Results : 1) After 21 days of the drug treatment, the risperidone group and the fluoxetine group showed significant difference from the haloperidol group and the saline control group on the protection of the 5-MeODMT induced suppression of spontaneous alternation behaviour. 2) The fluoxetine group and fluoxetine with haloperidol group showed significant difference between before and after treatment in the protection of 5-MeODMT induced suppression of spontaneous alternation behaviour. The risperidone group also showed significant difference between before and after treatment in the protection of 5-MeODMT induced suppression of spontaneous alternation behaviour, but the protective effect of risperidone was superior to fluoxetine. Conclusion : These findings suggest that both risperidone and fluoxetine have a favorable effect in the protection of 5-MeODMT induced suppression of spontaneous alternation behaviour. We think that risperidone can be possible alternatives to SSRIs in the treatment of refractory obsessive-compulsive disorder in clinical situation.

Background/Aims: We investigated the frequency of occult hepatitis B virus (HBV) infection in anti-hepatitis C virus (HCV)-positive individuals and the effects of occult HBV infection on the severity of liver disease. Methods: Seventy-one hepatitis B virus surface-antigen (HBsAg)-negative patients were divided according to their HBV serological status into groups A (anti-HBc positive, anti-HBs negative; n=18), B (anti-HBc positive, anti-HBs positive; n=34), and C (anti-HBc negative, anti-HBs positive/negative; n=19), and by anti-HCV positivity (anti-HCV positive; n=32 vs. anti-HCV negative; n=39). Liver biopsy samples were taken, and HBV DNA was quantified by real-time PCR. Results: Intrahepatic HBV DNA was detected in 32.4% (23/71) of the entire cohort, and HBV DNA levels were invariably low in the different groups. Occult HBV infection was detected more frequently in the anti-HBc-positive patients. Intrahepatic HBV DNA was detected in 28.1% (9/32) of the anti-HCV-positive and 35.9% (14/39) of the anti-HCV-negative subjects. The HCV genotype did not affect the detection rate of intrahepatic HBV DNA. In anti-HCV-positive cases, occult HBV infection did not affect liver disease severity. Conclusions: Low levels of intrahepatic HBV DNA were detected frequently in both HBsAg-negative and anti-HCV-positive cases. However, the frequency of occult HBV infection was not affected by the presence of hepatitis C, and occult HBV infection did not have a significant effect on the disease severity of hepatitis C.

Purpose: Capecitabine is an attractive oral chemotherapeutic agent that has a radiosensitizing effect and tumor-selectivity. This study was performed to evaluate the efficacy and toxicity of preoperative chemoradiation therapy, when used with oral capecitabine, for locally advanced rectal cancer. Materials and Methods: A prospective phase II trial of preoperative chemoradiation for locally advanced adenocarcinomas of the lower two-thirds of the rectum was conducted. A radiation dose of 50 Gy over five weeks and a daily dose of 1650 mg/m2 capecitabine in two potions was administered during the entire course of radiation therapy. Surgery was performed with standardized total mesorectal excision four to six weeks after completion of the chemoradiation. Results: Between January 2002 and September 2003, 61 patients were enrolled onto this prospective phase II trial. The pretreatment clinical stages were T3 in 64% (n=39), T4 in 36% (n=22) and N1-2 in 82% (n=50) of these patients. Fifty-six (92%) patients completed the chemoradiation as initially planned and a complete resection performed in 58 (95%). Down-staging was observed in 45 patients (74%) and a pathologic complete response in 6 (10%). Among the 37 patients with tumors located within 5 cm from the anal verge on colonoscopy, 27 (73%) underwent a sphincter-preserving procedure. No grade 3 and 4 proctitis or hematological toxicities were observed. Conclusion: Preoperative chemoradiation therapy with capecitabine achieved encouraging rates of tumor down- staging and sphincter preservation, with a low toxicity profile. This combined modality can be regarded as a safe and effective treatment for locally advanced rectal cancer.(Cancer Res Treat. 2004;36:354-359)
