The study was carried out to investigate the effects of dietary carotenids and β-carotene on the hematological changes caused by alcohol administration into the rats. The results were analyzed using several statistical methods; SPSS computer program for measuring the mean values and standard deviations, one way ANOVA for the test of significance, Duncan method for post HOC multiple comparison, and Pearson method for measuring the correlation coefficient. The following are the conclusion from those statistical analysis. 1. ALB and TB were shown to have the most significant correlation among the blood compositions f개m the basic dietary groups. 2. BUN and CHO were shown to have the most positive correlation among those from the carrot-fed groups. 3. CA and AG were shown positively correlated, and CHO and IP negatively correlated, respectively among those from the cheese-fed groups. 4. AP was shown positively correlated among those from the alcohol-administrated groups. 5. CHO, CA and BUN were shown positively correlated, and CA was negatively correlated among those from the β-Carotene -fed groups. 6. TB and TP were not affected by the correlations between the blood composition from all the experimental groups.

Purpose: The postoperative maxillary cyst (POMC) develops as a delayed complication of many years after surgical intervention in maxillary sinus. We report a case of postoperative maxillary cyst invaded into the orbit causing displacement of the globe, which was successfully treated with drainage under nasal endoscopy. Subject and Method: A 38-year-old man visited the hospital complaining of palpable mass on his right lower eyelid area for -10days. He had had CaIdweII-Luc operation for maxillary sinusitis for 10 years ago. Examination revealed hard and painless palpable mass on his right lower eyelid area. Computed tomographic (CT) scan of head and orbits revealed a low density, cystic mass in the right maxillary sinus invaded into the orbit, displacing the globe superiorly. We found a bulging cystic mass supero-posterior to the middle turbinate, and we performed incision and drainage under nasal endoscopy. Result: At third postoperative day, successful treatment of cystic mass was confirmed by nasal endoscopy, with disappearing of palpable mass on right lower eyelid area. Conclusion: We suggest that nasal endoscopic surgery in treatment of postoperative maxillary cyst invaded; into the orbit maybe effective method.

The purpose of this study is to investigate the biofilm reactors capable of doing high efficiency treatment. Vertical fluidized bed biofilm reactor(VFBBR) and spiral fluidized bed biofilm reactor(SFBBR) was used for their performence in biodegradation of artificial sewage. The factors influencing the efficiency of those reactors were compared with difference of physical condition. They had same size but different structure to gain access of its unique characteristics. When recycle solution with flow rate of 22 mL/min and artificial sewage with flow rate of 2-10 mL/min were fed into two reactors in aerobic state, the average COD, removal rate for biodegradation of SFBBR was greater than VFBBR. After reactor feed sewage was constantly maintained as flow rate of 4 rnL/min and the recycle solution were changed to 10-32 mL/min respectively, the average COD,, removal rate of artificial sewage in SFBBR was greater than VFBBR. In this experiment for addition of support media into two reactors SFBBR was 4.1% excellent than VFBBR. Above all, SFBBR excelled VWBR in boidegradation of organic matter in sewage.

Purpose: Persistent pupillary membrane(PPM) can be classified as four types by means of its morphology. Type 2, which is attached to the lens, is very rare and can cause visual disability. We report 3 cases of type 2 PPM that shows a good visual acuity and cosmetic improvement after removal. Methods: We chose 3 female who showed a poor visual outcome and abnormal shaped pupil since a child. All of 3 case could be examined a hyperplastic persistent pupillary membrane by slit lamp biomicroscopy. Treatment was a surgical removal of PPM, and a surgical removal of PPM and cataract operation in one case of PPM with cataract. Results: All of 3 patient showed a good visual acuity and cosmetic improvement, Conclusion: Surgical management should be also considered to good visual acuity and cosmetic improvement to PPM observed in adult eye.

목적: 간의 국소 결정성 과형성은 일반적으로 특별한 치료가 필요 없는 양성 종양이다. 그러나 드물지만 합병증이 발생한 경우와 진단이 불확실한 경우에는 수술을 시행하게 된다. 이에 저자들은 간절제술을 시행한 국소 결절성 과형성의 임상적, 영상학적 특징들을 알아보고자 하였다. 대상과 방법: 1995년부터 2003년까지 수술을 시행하여 조직을 확인한 국소 결절성 과형성 환자 10명을 대상으로 연령, 성별, 실험실 검사 및 영상 소견과 조직 소견을 분석하였다. 결과: 연령의 중앙값은 37.5세, 남녀 비는 1.5:1이었다. 5예에서는 간세포선종이나 간세포암종을 감별할 수 없어서 수술을 시행하였으며, 수술 후 우연히 진단된 예는 4예이었다. 간세포암종의 위험 인자를 가지고 있었던 예는 4예(B형 간염 바이러스 보유자 3예, 간경변 2예)이었다. CT검사가 시행되었던 6예 중 5예는 동맥기에서 조영 증강을 보였고 문맥기 및 지연기로 감에 따라 주변과 동일(4예)한 또는 감소(2예)되는 양상을 보여 간세포암종과의 감별이 어려웠다. 크기는 3.2±2.2㎝이었으며 위치는 간우엽의 후하구역(S6)에 가장 많았다(30.0%). 4예에서 수술 전 침생검을 시행하였으나 고분화 간세포암종이나 간세포선종과의 감별이 어려웠다. 결론: 임상상, 영상검사 및 간침생검으로도 간세포암종이나 간세포선종과의 감별이 어려운 경우 수술을 시행하였으며 수술 전에는 발견하지 못하였지만 다른 질환으로 인한 수술시 우연히 발견된 경우도 있어 국소 결절성 과형성의 수술 전 진단이 어려운 경우가 적지 않음을 알 수 있었다. Background/Aims: Focal nodular hyperplasia (FNH) is a benign hepatic tumor with few serious complications and no malignant transformation. However, differential diagnosis between FNH and other liver tumors, especially hepatocellular carcinoma, is often difficult. Methods: Clinical features of surgically resected FNH were reviewed. From January, 1995 to February, 2003, 10 patients with surgically resected FNH were enrolled. Their age, sex, results of laboratory examination, imaging studies and pathologic findings were evaluated. Results: Median age was 37.5 years and sex ratio (male:female) was 1.5:1. In 5 cases, resection to exclude hepatic adenoma or HCC was performed. Four cases were diagnosed incidentally after surgery. Four patients had risk factors for HCC, such as hepatitis B virus infection, liver cirrhosis or both. The size of FNH was 3.2 2.2 cm. The most common site of the tumor was segment 6 (30.0%). Differential diagnosis with HCC was difficult in 5 of six cases in whom CT was performed. Although needle biopsies were performed preoperatively in 4 cases, it was difficult to distinguish FNH from hepatic adenoma or HCC. Conclusions: FNH was resected due to uncertainty of diagnosis, or incidentally during hepatectomy in patients with other liver disease. In the former, differential diagnosis with hepatic adenoma or HCC was a major problem despite extensive work-up including dynamic CT or biopsy. (Korean J Hepatol 2004;10:135-141)
