OBJECTIVES: The objectives of this study is to compare the differences of fetal heart rate (FHR) variables between preterm and term pregnancies after acoustic stimulation using computerized analysis of fetal heart rate. METHODS: Eighty-two normal pre-term and term pregnancies entered to this study after conventional 20-minutes nonstress test(NST) and 10-minutes acoustic stimulation test (AST). Acoustic stimulations were performed using Fetal Acoustic Stimulator (Model 146, Corometrics, US). We analyzed the FHR response after acoustic stimulation using our on-line computerized FHR analysis system, HYFM-I & II software. The changes of loss of signal, baseline FHR, variability, number of fetal movements, and number of FHR accelerations were analyzed numerically. RESULT: The mean baseline FHR was increased in term pregnancies from 141+/-7.0bpm to 152.7+/-9.7bpm, and in preterm pregnancies from 144.6+/-6.8bpm to 156.8+/-10.2bpm, respectively. The mean baseline FHR was significantly increased in both term and preterm pregnancies (p<0.01. paired t-test). The variability of FHR was increased in term pregnancies from 18.2+/-6.4bpm to 22.6+/-5.0bpm and in preterm pregnancies from 17.8+/-5.5bpm to 22.7+/-5.9bpm, respectively. The variability of FHR was also significantly increased in both term and preterm pregnancies. (p<0.01. paired t-test) CONCLUSION: The mean baseline FHR and the variability of FHR was significantly increased both preterm and term pregnancies. But the difference of each FHR variables between preterm pregnancies and term pregnancies was not statistically significant in this study.

PURPOSE: To evaluate further the right minor and major fissure on thin-section narrow-interval CT scans with particular emphases on orientation, degree of completeness. MATERIALS AND METHODS: Thin section CT scans from 10 mm distal to carina to the proximal basal segmental bronchus were obtained at 5 mm invervals in 50 consectutive subjects. Orientation, degree of completeness, and the relationship of the minor and major fissure on thin-section CTscans were analyzed. RESULTS: Four principal types of the minor fissure could be identified according to the highest point of the upper surface of the middle lobe. At bronchus intermedius level, the major fissure appeared with its medial end anterior to lateral end in 45 subjects. The minor fissure was complete in only 10 subjects (20%). Completely absent minor fissure was noted in four subjects (8%). The major fissure was incomplete in 17 subjects (34%) at bronchus intermedius level. the minor and major fissure intersected each other in only 27 subjects (54%). The hig best point of intersection was variable. CONCLUSION: There are much more variations in the fissural complex in our study than in previous reports and these variations can be visualized well on thin-section CTscans.

Experiments were conducted to define the optimal constituents of culture medium and atmospheric condition for growth of Campylobacter pylori. Two clinical isolates were streaked onto various media, incubated in two different atmospheric conditions (microaerophilic condition and carbon dioxide incubator), and growth was assessed semiquantitatively according to relative colony size and extent of growth through the streak. The growth obtained on Campy media, composed of GC agar base plus 1% hemoglobin, 0.2% activated charcoal, 1% IsoVitaleX, vancomycin 6mg /L nalidixic acid 20mg/L and amphotercin 2 mg/L, was used as reference. Our conclusions were as follows: Tryptic soy agar base was not acceptable for the growth of C. pylori. The organism grew in both atmospheric conditions, but generally showed a scantier growth in the carbon dioxide incubator than under the microaerophilic condition, however GC agar containing 1% hemoglobin and 0.2% activated charcoal supported well the growth of C. pylori in the carbon dioxide incubator. The authors have found that the GC agar base supplemented with 1% hemoglobin and 0.2% charcoal was the most satisfactory medium and a microaerophilic condition was optimal atmospheric condition for the growth of Campylobacter pylori in this study.

The CT findings were reviewed in two patients with injuries to the gallbladder following blunt trauma. In one patient high attenuation of intraluminal blood clot within the gallbladder and associated hemoperitoneum were identified. Another patient was represented hemoperitoneum and bile leakage into the peritoneal cavity due to laceration of the fundus of the gallbladder which appeared contrasted.

PURPOSE: To determine the long-term follow-up CT findings of paraquat-induced lung injury. MATERIALS AND METHODS: Six patients who ingested paraquat underwent sequential follow-up CT scanning during a period of at least six months, and the results were analysed. Scans were obtained 1-6 (mean, 3.3) time during a 7-84 (mean, 25.7) months period, and the findings at 1-2 months, 3-12 months, 1-2 years, 2-3 years, and more than above 7 years after poisoning were analyzed. RESULTS: We observed irregular-shaped areas of consolidation with traction bronchiectasis at 1-2 months (5/5), irregular-shaped consolidation and ground-glass opacity (5/5) at 3-12 months, and irregular-shaped consolidations/ ground-glass opacity (4/5) and focal honeycombing (1/5) one year later. In the same patients, follow-up CT scans showed that some areas of focal consolidation could not be visualized and the radio-opacity of the lesions had decreased. CONCLUSION: The HRCT findings of paraquat-induced lung injury were irregular shaped areas of consolidation 1-2 months after ingestion, and irregular-shaped consolidation and ground-glass opacity or focal honeycombing 3-12 months later. At this thim slight improvement was observed.

A study to evaluate the diagnostic significance of M. pneumoniae Infection by measurements of cold agglutinin and antimycoplasma antibody titers is performed with 191 pediatric patients who have visited Yeungnam University Hospital during the period through January to July, 1987. Forty eight of 191 cases made follow up tests feasible. The results obtained are as follows: 1. It is necessary to perform routine combined measurements of cold agglutinin and antimycoplasma antibody titers for the all pediatric pneumonia caser since a large proportion of pneumonia in children is caused by M. pneumonia. 2. For the diagnosis of M. pneumoniae Infection, measurements of cold agglutinin titer alone seems to be less significant than to check both cold agglutinin and antimycoplasma antibody titers. 3. The measurement of antimycoplasma antibody titer appeared to be more specific than cold agglutinin test in the diagnosis of M. pneumoniae Infection. 4. The present study urges the necessity of follow up study of cold agglutinin and antimycoplasma antibody titer for those who initially presented with normal titers in both tests, but are clinically suspected for M. pneumoniae Infection.
