The inheritance of ABO blood type group is actually determined by triple allelic gene, A, B and O. Transmission of blood group AB by a single chromosome, instead of by two separate chromosomes, was reported and called cis AB. The anesthesiologists, who meet many cases of the transfusions, may anesthetize cis AB patients for surgery. Recently the authors have experienced one case of patient with cis AB blood type undergoing emergency craniotomy and removal of hematoma. We transfused the patient with Rh+O packed red blood cell without any significant transfusion reactions.

PURPOSE: To compare the survival rates of patients with hepatoma using different methods of transcatheter arterial chemoemblization(THAE). MATERIALS AND METHODS: Four hundred and eighty three patients with hepatoma diagnosed by biopsy, serum alpha-fetoprotein, abdominal CT scan, abdominal ultrasonography or hepatic angiography were included, but not all had reccived surgical treatment. They were divided into two groups according to Child's classification and into subgroups according to different methods of THAE. Five-year survival rates among these groups were retrospectively Compared. The patients were aged between 24 and 85(mean, 58) ; male to female ratio was 324:61 for those who received THAE (396:87 when only hepatic angiography was considered). RESULTS: In the group with more than a single episode of chemoembolization, regardless of Child's classification, a better survival rate compared to the other groups with or without concommitant radiotherapy or without chemoembolization was noted. There was no difference in the survival rate of patients with multiple chemoembolization. Moreover, no difference in this rate was observed no matter what chemotherapeutic agents, including Adriamycin, Cis-Diaminedichloroplatinum or 1-131-Lipiodol, were used. Embolization by gelfoam in conjuction with Adriamycin resulted in no difference in survival rate regardless of requency of chemoembolization. CONCLUSIONS: An improved survival rate was seen when multiple episodes of chemoembolization were applied, but no difference was seen when there was concomitant application of either gelfoam or radiotherapy. Two different chemotherapeutic agents,Adriamycin and Cis-Diaminedichloroplatinum, were used, but there was no difference between them in their effect on survival rates.

Endobronchial leiomyoma is extremely rare and accounts for less than 2% of benign tumors of the lower respiratory tract. Leiomyomas are predominantly found in the young and the middle aged : of the average age being 35 years for bronchial and lung parenchymal lesions and 40.6 years for tracheal lesions. The symptom depends on the location of the tumor, its size, and changes in the lung distal to the lesion. A 37-year-old woman was admitted to our hospital complaining of coughing. Bronchoscopy revealed complete obstruction of the right main bonchus at the carina by an oval-shaped, nonulcerative, smooth, and pinkish-tan tumor with a broad margin and extended to the left main bronchus. A biopsy was performed and showed a benign spindle cell tumor. A right pneumonectomy was performed because of chronic infection, and the lung could not expanded during aeration. The histological diagnosis of the resected specimen was leiomyoma. The postoperative course was uneventful.

PURPOSE: To examine the danger zone of mesial root of mandibular first molar of patient without extraction using CBCT(cone -beam computed tomography) to avoid the risk of root perforation. MATERIALS AND METHODS: 20 mandibular first molars without caries and restorations were collected. CT images were obtained by CBCT(PSR9000N TM, Asahi Roentgen Co., Japan), reformed and analyzed by V-work 5.0 (CyberMed Inc., Korea). Distance between canal orifice and furcation was measured. In cross sectional images at 3, 4 and 5 mm below the canal orifice, distal wall thickness of mesiobuccal canal (MB-D), distal wall thickness of mesiolingual canal (ML-D), distal wall thickness of central part (C-D), mesial wall thickness of mesiobuccal canal (MB-M) and mesial wall thickness of mesiolingual canal (ML-M) were measured. RESULTS: The mean distance between the canal orifice and the furcation of the roots is 2.40 mm. Distal wall is found to be thinner than mesial wall. Mean dentinal wall thickness of distal wall is about 1 mm. The wall thickness is thinner as the distance from the canal orifice is farther. But significant differences are not noted between 4 mm and 5 mm in MB-D and C-D. MB-D is thinner than ML-D although the differences is not significant. CONCLUSION: The present study confirmed the anatomical weakness of distal surface of the coronal part of the mesial roots of mandibular first molar by CBCT and provided an anatomical guide line of wall thickness during endodontic treatment.

Phase and Amplitude Image were developed to overcome the subjective nature of interpretation for cinematic endless loop display of radionuclide gated blood pool scan. To evaluate the usefulness of color coded phase image in coronary artery disease, we conducted a clinical study with coronary angiography and phase image in 23 patients, and compared the results of those studies. 1) The results of coronary angiography revealed normal coronary artery in 6, 1 vessel disease in 11, 2 vessel disease in 4, and 3 vessel disease in 2 patients. 2) Color-coded Phase Image revealed abnormal phase area in 2/2(100%) of 3 vessel disease patients and in 3/4(75%) of 2 vessel disease patients, in 5/11(45%) of 1 vessel disease patients, and only 1/6(16%) of normal coronary artery. 3) Among the patients who disclosed abnormal phase image, 5 patients of 2-or3-vessl disease revealed abnormal phase through whole left ventricular area, but 3 patients with right coronary artery lesion and 2 patients with left antrior descending artery lesion showed localized abnormal phase area, infero-apical and anterior portion respectively, which were in accord with each coronary lesion. We concluded that the phase image may be useful in evaluation of the regional wall motion abnormalities in the patients of coronary artery disease. Further studies seem to be neccessary to clarify the sensitivity and specificity of the phase image in the each disease entity group.

OBJECTIVE: This study compared the diagnostic accuracy of computed tomography (CT) angiography in patients with various severities of gastrointestinal hemorrhage (GIH). METHODS: We retrospectively enrolled adult patients (n=262) with GIH who had undergone CT angiography from January 2012 to December 2013. Age, sex, comorbidities, presenting symptoms, initial vital signs, laboratory results, transfusion volume, emergency department disposition, and hospital mortality were abstracted from patient records. CT angiography findings were reviewed and compared to reference standards consisting of endoscopy, conventional angiography, bleeding scan, capsule endoscopy, and surgery, either alone or in combination. Clinical severity was stratified according to the number of packed red blood cell units transfused during the first two days: the first quartile was categorized as mild severity, while the second and third quartiles were categorized as moderate severity. The fourth quartile was categorized as severe. RESULTS: Patients were categorized into the mild (n=75, 28.6%), moderate (n=139, 53.1%), and severe (n=48, 18.3%) groups. The mean number of transfused packed red blood cell units was 0, 3, and 9.6 in the mild, moderate, and severe groups, respectively. The overall sensitivity, specificity, positive predictive value, and negative predictive value of CT angiography were 73.8%, 94.0%, 97.3%, and 55.3%, respectively. The area under the receiver operating characteristics curve for the diagnostic performance of CT angiography was 0.780, 0.841, and 0.930 in the mild, moderate, and severe groups, respectively, which significantly differed among groups (P=0.006). CONCLUSION: The diagnostic accuracy of CT angiography is better in patients with more severe GIH.

BACKGROUND/AIMS: Epidermal growth factors (EGF) is known to activate mitogen activated protein kinase (MAP kinase) in hepatocytes by the route of both Raf-dependent and Raf-indefendent pathways. And this is likely to play important role in normal liver cell growth and regeneration. EGF is also reported as a potent mitogen and one of the angiogenic factors. To elucidate the dynamic changes of the serum concentration of epidermal growth factor in chronic liver disease and its correlation with role of EGF and mechanism of tumor development, this study is intended to employ an ELISA in 38 biopsy-proven cases. METHODS: Sera taken out of 5 patients with chronic persistent hepatitis. 4 patients with chronic active hepatitis, 19 patients with liver cirrhosis, 10 patients with hepato-cellular carcinoma that pathological diagnosis was proven later were tested for EGF employing Quantikine ELISA Kits (R & D Systems Inc. Minneapolis, MN). The statistical analysis was evaluated by student's t-test. RESULTS: EGF concentration was 253.33+ 69.5pg/ml(Mean+ SE) in hepatocellular carcinoma, 246.60+ 91.19pg/ml(Mean+ SE) in chronic active hepatitis, 222.71+ 115.97pg/ml (Mean+ SE) in chronic persistent hepatitis, 141.15+ 23.12pg/ml(Mean+ SE) in liver cirrhosis in orders. Serum EGF concentration in hepatocellular carcinoma was significantly higher than that in liver cirrhosis(p value=0.021695). However, comparing to the remaining other groups, no significant difference was found. CONCLUSION: These results support that the reconstruction of the capillary networks in liver cirrhosis resplts in down-regulation of the EGF in comparison to chronic hepatitis. But it is suggested that revaluation of EGF stimulates MAP kinase activity eventually playing in tumorigenesis of the liver with neoangiogenesis.
