Nitroblue tetrazolium dye reduction test is now widely used for early detection of bacterial infection. Practically nitroblue tetrazolium dye reduction test (N.B.T. test) gives certain clue to rule out any possibility of aseptic inflammation. Authors performed N.B.T. test for 80 orthopaedic diseases and 40 controls, and the results were as followings: 1. Forty-one of 60 subjects with bacterial infection had more than 10% formazan positive neutrophils, and 18 of 20 subjects without bacterial infection showed less than 10%. formazan positive neutrophils, The groups of the elevated N.B.T. responses were mainly the subjects who had osteomyelitis, soft tissue inflammation, pyogenic arthritis, and bone and joint tuberculosis. 2. The mean proportion of N.B.T. positive neutrophils was 3.8±2.78% in 40 controls, 4.7±4.23% in 20 nonifectious group 12.7±10.3% in 12 chronic osteomyelitis, 12.5±10.7% in 15 treated bone and joint tuberculosis, 20.9±15.65% in 15 untreated bone and joint tuberculosis and 20±10.70% in 11 pyogenic arthritis and 7 other soft inflammatory group. 3. In noninfectious group, 7 of 8 subjects with elevated ESR and 3 of 4 subjects with elevated body temperature revealed N.B.T. responses less than 10%. 4. In 23 subjects with the elevated N.B.T. responses as well as leukecytosis, 22 subjects were the groups of bacterial infection and rest 1 was noninfectious in nature. 5. Therefore, the N.B.T. test is found to be useful for the purposes of the early diagnostic aid of the bacterial infection and differential diagnosis between bacterial infections and other diseases.

There has been so much controversies about the position of upper and lower jaws, and their first permanent molars in normal occlusion and Angle's class I,II,III malocclusions. So, the purpose of this study is to compare the position of upper and lower jaws, and their first molars in normal occlusion and Angle's class IIIIII malocclusions by lateral cephalometric analysis. The sample consisted of one hundred and twenty girls(thirty in each group) who had completed growth. The findings of this study were as follows: 1. In class I malocclusion, both maxilla and mandible were slightly posterior position than normal occlusion, but they showed harmonious relationship. 2. In class II malocclusion, the mandible was greatly retruded, and the maxilla was also slightly retruded to the cranial base as compared with normal occlusion. 3. In class III malocclusion, the maxilla was significantly retruded to the cranial base, but no significant difference was found in mandibular position as compared with normal occlusion. 4. The maxillary first molar was located at posterior position in class II malocclusion, and anterior position in class III malocclusion to the cranium, so that the rotation of mandible was influenced by that. 5. The mandibular first molar showed constant relationship to the mandible in all four groups, but different position to the cranial base in direct proportion to the mandibular position. 6. On the treatment planning of class II malocclusion, it seems to be better to promote the mandibular horizontal growth by inhibiting the vertical growth of maxillary molar area, and on the treatment planning of class III malocclusion, it seems to be better to promote the antero-inferior growth of maxilla and to promote the mandibular vertical growth by inducing the vertical growth of maxillary molar area.

Percutaneous balloon valvuloplasty (PBV) was done in 7 adults of pulmonary valvular stenosis, which was diagnosed with catheterization and cine-angiography of rigtht heart, in Seoul National University Hospital from Jan. 1986 to Dec. 1986. The results were as follows : 1) Among the seven cases six were male and the range of age was from 19 to 40 years. Atrial septal defects associated in 2 cases were not significant clinically. 2) The peak systolic gradient from right ventricle to pulmonary artery before the procedure was below 50 mmhg in 1 cases, 50 to 100 mmHg in 1 case, and above 100 mmHg in 5 cases. 3) Before PBV the mean systolic pressure of right ventricle was 121+/-42 mmHg and the peak systolic gradient was 106+/-41 mmHg. After PBV those were 58+/-30 mmHg and 40+/-31 mmHg, revealing significant improvement. 4) Balloon catheter (Medi-tech, 9F) was used in all cases. single balloon of 20 mm outer diameter was applied in 2 cases and double balloons of various sizes were applied in 5 cases in which single balloon showed inadequate dilatation. It is suggested that percutaneous balloon valvuloplasty is safe and effective alternative to surgical valvotomy of pulmonary valvular stenosis in adults.

According to the reports, the prevalence of anti-HCV is about 1%. In past, the results of the prevalence of HBs Ag & HBs Ab in the patients of Hansen's disease were reported. But we don't know about that of anti-HCV. So we study about the prevalence of serum anti-HCV of 60 patients & PALS of Hansen's disease. And we test about Alk. Phosp., ALT, AST, Gtlc HBs Ag & HBs Ab. 1. The prevalence of anti-HCV is 8.33%. It is higher than past reports(about 1-2%). 2. The prevalence of HBs Ag is 3.4% & that of HBs Ab is 36.3%. 3. Because of the high prevalence of anti-HCV in the patients of Hansen's disease & PALS, we think that more studies are need about it.

BACKGROUND/AIMS: The risk of cardiovascular morbidity and mortality is high in patients with diabetes. Since studies suggest that aspirin is less effective in diabetic patients, this study evaluated the prevalence of aspirin resistance and related factors in Korean type-2 diabetics. METHODS: All patients taking aspirin 100 mg/day for at least 4 weeks and no other anti-platelet agents were enrolled. The compliance of aspirin intake was determined from patient interviews and using the pill-count method. All other medications were continued during the study, including oral hypoglycemics, antihypertensives, and lipid-lowering agents. The effect of aspirin was assessed using the Ultegra Rapid Platelet Function Assay-ASA (VerifyNow-Aspirin, Accumetrics, San Diego, CA) and aspirin resistance was defined as >550 aspirin reaction units (ARU). RESULTS: The prevalence of aspirin resistance in Korean type-2 diabetics was 14.8%, and was more prevalent in males than in females (28.1% vs. 7.1%). Aspirin resistance was correlated with male sex, smoking, high hemoglobin levels, a high estimated glomerular filtration rate (GFR), and low fibrinogen levels. After controlling for sex, aspirin resistance was related to the estimated GFR (r=0.247, p=0.029), hemoglobin (r=0.23, p=0.043), and fibrinogen (r=0.304, p=0.007) levels. CONCLUSION: The prevalence of aspirin resistance in Korean type-2 diabetics was 14.8%. Therefore, a laboratory test for aspirin resistance should be considered in diabetic patients taking aspirin to prevent cardiovascular complications.

Plasma renin activity (ORA) was determined by radioimmunoassay in 55 normal controls and 121 hypertensive patients in basal state and after double stimulation with furosemide administration and upright posture of 4 hrs. The results were obtained as follows, 1) Mean value of PRA of normal control was 2.2+/-1.41ng/ml/hr in basal state and 2.9+/-1.39ng/ml/hr after double stimulation, respectively. The latter was elevated significantly as compaired to the former. 2) PRA in males was significantly higher than in females, and PRA tend to be decreased as age become old. 3) Normal value of PRA after double stimulation was ranged from 1.0 to 5.0 ng/ml/hr. Of total 121 hypertensive patients(55 males and 66 females), PRA was low in 33 cases(27.3%), normal in 77 cases (63.6%), and high in 11 cases(9.1%). 4) Of 55 male hypertensive patients, PRA was low in 13 cases(23.6%), normal in 35 cases (63.7%), and high in 7 cases(12.7%). Of 66 female hypertensive patients,, PRA was low in 20 cases (30.3%), normal in 42 cases(63.6%), and high in 4 cases(6.1%). High renin group was observed more frequently in male hypertensive patients than in female hypertensive patients, while low renin group more frequently in famale than in male patients. 5) Low renin group was observed more frequently in older age group than in younger age group, while high renin group more frequently in younger age than in older age group.

The presence of metastatic lymph nodes in cervical carcinoma is one of the most important prognostic factors to survival. In general, the characteristics of metastatic lymph nodes such as number, site, and bilaterality etc. can modify the survival of patients with lymph node metastasis. This nonrandomized retrospective study was performed to identify prognostic factors for survival in patients with FIGO stage IA2, I B and IIA, IIB carcinoma of the cervix with nodal metastases. From January 1, 1993, to December 31, 1995, 86 patients with FIGO stage I A, I B and IIA, IIB carcinoma of the cervix were found to have nodal metastasis at the time of radical hysterectomy and pelvic lymphadenectomy at the Department of Obstetrics and Gynecology, Korea Cancer Center Hospital. The prognostic significance of number of metastatic lymph nodes, site(s) of lymph node metastases, cervical lesion size, age, FIGO stage have been evaluated. In this study, the 3-year disease free survival rate (DFSR) and clinical characteristics were compared with the prognostic factors. Univariate analysis revealed significant that number of metastatic lymph nodes (p=0.0008) and tumor size (p=0.0490) were significant prognostic factor, but there were no significant differences in 3-year DFSR according to age (p=0.1257), FIGO stage (0.4687), site(s) of lymph node metastases (p=0.5552). However, by multivariate analysis only number of metastatic lymph nodes (p=0.0248) was noted to be a significant prognostic factor determining survival of the patient. A risk of recurrence increased continuously in accordance with increased of the number of metastatic lymph nodes. In particular the 3-year DFSR fell markedly from 85.3% in patient with less than four metastatic lymph node to 25.9% in those with five or more metastatic lymph node (p=0.0008). These results demonstrated that the number of metastatic lymph nodes was the most important and independent prognostic factor in patients with cervical cancer showing lymph node metastasis.

Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is a slowing progressive ataxic disorder characterized by bilateral vestibulopathy, cerebellar ataxia and somatosensory impairment. Autonomic dysfunction is recently considered as a core feature in CANVAS in addition to these symptoms. In most cases, patients with CANVAS show cerebellar atrophy in brain imaging, but some cases show minimal or no atrophy of cerebellum. Brain (18F)-fluoro-2-deoxy-D-glucose positron emission tomography (¹⁸F-FDG PET) study can be a complimentary tool to diagnosis CANVAS in cases of no structural abnormality such as cerebellar atrophy. Hereby, we present a case of CANVAS with minimal atrophy of cerebellum but showing a prominent hypometabolism in cerebellum, thalamus and posterior cingulate cortex in ¹⁸F-FDG PET.
