Peripheral blood stem cells(PBSC) were collected for autologous transplantation for the first time in Korea wish Fenwal CS-3000 Plus blood cell separator. Twenty-nine procedures were performed for 7 patients without any incidents. GM-CSF(400ug) was administered daily for 5 days before PBSC collection and the collections were performed 3-6 successive days. A total of 3.5-11.4 x 109 mononuclear cells(MNCs) were collected from 7,000mL blood processed per procedure. The number of MNCs collected was mainly dependent on the concentration of MNCs in patient's blood(r = 0.68, p<0.01). We concluded that the PBSC trans plantation program could be set up without difficulty in Korea since the Fenwal CS-3000 Plus blood cell separator is already available in many institutions and the procedure used in this study is easy to follow.

A 38-year-old man, with recurrent oral ulcers for 10 years, was admitted because of recent aggravation of odynophagia and sore throat. About 4 years earlier, he had been performed abdominal surgery for intestinal perforation. Gastrofiberscopic examination showed small round ulcers at hypiopharynx and 6cm sized longitudinal linear ulcer at mid esophagus. Biopsy specimens at mid-esophagus showed chronic inflammation. Besides oral ulcer, he had perianal ulcers and skin rashes. He was managed with steroid, colchicine and sulfasalazine under the diagnosis of esophageal involvement in Behcet's disease. After 3 months from discharge, esophagogram and gastrofiberscopic examination showed some improved appearance, but symptoms recurred for steroid tapering. He has been followed in much improved status for 8 months after discharge.

To find out the predictors of nocturnal arterial oxygen desaturation in patients with respiratory diseases, transcutaneous oxygen saturation(StcO2) monitoring studies using a pulse oximeter were performed during sleep in 20 patients. StcO2 was decreased more than 4% from the baseline value in 18 patients(90%) and more than 10%('Desaturator') in 8(40%). Five of the seven patients(71.4%) with awake PaO2<60mmHg and three of the thirteen patients(23.1%) with awake PaO2≥60mmHg were 'desaturators'. The awake PaO2/FIO2 and PaO2/PAO2 could distinguish 'desaturator' from 'nondesaturator, and PaO2, SaO2 or StcO2 could not. These results suggest that the nocturnal oxygen desaturation depends on the severity of the underlying disease rather than the baseline PaO2. Anthropomorphic and lung function factors could not separate between 'desaturator' and 'non-desaturator', and about a quarter of patients with a wake PaO2≥60mmHg developed significant desaturation. Therefore, it is necessary to monitor the nocturnal arterial oxygen saturation in patients with respiratory diseases regardless of their severity of airflow obstruction or awake PaO2.

BACKGROUND: It is known that QT dispersion represents asynchronous repolarization of ventricle which is related to ventricular fibrillation. The incidence of ventricular arrhythmia is increased after acute myocardial infarction. So this study compared QT dispersion and other repolarization indexes for detection of asynchronous repolarization in acute myocardial infarction. We also investigated which portion of repolarization is the key portion of the asynchrony. METHODS: In 37 acute myocardial infarction patients and 38 angina patients dispersion of QT, JT, JTpeak and QTpeak were measured. We also measured maximum adjacent dispersion of same parameters in precordial leads. In 20 survived patients and 17 dead patients after acute myocardial infarction were also compared. We also investigated correlation of PVC's on Holter monitoring with these repolarization parameters. RESULTS: 1) All ventricular repolarization indexes(QT, QTc, JT, JTpeak, QT peak and TpeakTend dispersion) were significantly increased in acute myocardial infarction group than compared with those of angina group(p<0.05). 2) Maximal precordial dispersion(QT, QTc, JT, JTpeak and QTpeak) were also significantly increased in acute myocardial infarction group than angina group(p<0.05). 3) Dead patient group after myocardial infarction showed significantly increased QTc and TpeskTend dispersion compared with those of survived patient group(p<0.05). 4) Multivariate linear correlation showed that TpeakTend dispersion and JT dispersion was correlated with QT dispersion. CONCLUSIONS: There were asynchronous myocardial repolarization changes in acute myocardial infarction. Our study demonstrated that T wave change was major determinant of dispersion of myocardial repolarization.

OBJECTIVES: The purpose of this study was to determine the clinical significance of residual amniotic fluid volume, as measured by the amniotic fluid index(AFI), on the prediction of latency period and perinatal outcomes in patients with preterm premature rupture of the membranes(PPROM). METHODS: Study population consisted of 103 singleton pregnancies with PPROM between 24 and 34 weeks' gestation. Amniotic fluid index was determined using transabdominal ultrasound at admission. Latency period was defined as time interval in hours between admission and delivery. All medical records of mothers and neonates were reviewed. Spearman's rho rank correlation, receiver-operator characteristic(ROC) curve analysis, survival analysis and Cox's proportional hazard model were used for statistical analysis. RESULTS: There was a statistically significant correlation between latency period and AFI at admission. ROC curve analysis showed that AFI at admission had a significant predictive value in the prediction of latency period < 48 hours. Survival analysis demonstrated that AFI < 5.0 was strongly associated with the likelihood of shorter latency period, Cox's proportional hazard model indicated that AFI < 5.0 was a significant independent predictor for the occurrence of latency period < 48 hours even after adjustment of other independent variables. The patients with AFI <5.0 had a higher rate of cesarean section due to fetal distress than those with AFI > 5.0 but the incidence of chorioamnionitis was not significantly different between two groups. Comparing the perinatal mortality and neonatal morbidity including infectious morbidity between the neonates born to mothers with AFI <5.0 and those with AFI > 5.0, there was no significance after adjustment of gestational age at birth. CONCLUSION: AFI at admission has a significant correlation with latency period and predictive value in prediction of latency period in the patients with PPROM. AFI <5.0 is a independent predictor for the shorter latency period.
