Acoustic stimulation test(AST), is currently being used as an alternative tool of nonstress test (NST). However, there are no standard guideline for analysis of AST. Computerized numerical analysis of AST would be helpful for development of diagnostic criteria of AST. Fifty-one normal pre-term pregnancies entered to this study after conventional 20-minutes NST and 10-minutes 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. The loss of signal was increased about 2 fold(122.61%). The baseline FHR was increased from 144.57bpm to 156.81bpm(8.5%) after acoustic stimulation. Number of fetal movements was increased about 2 fold(from 2.1 to 4.12/10 minutes). FHR variability was also increased from 17.81 bpm to 26.37 bpm. After AST, number of FHR accelaration was increased 55.47%(10sec 10bpm) and 68.42%(15sec 15bpm), respectively. In this study, we acrumulated elemental FHR data using computerized system after AST. These data would be helpful in the accurate analysis of AST and also enable us to develop the objective interpretation system for AST.

Transient hyperkalemia is well known to occur in man following intravenous administration of succinylcholine chloride. We studied the change of the serum potassium concentration after injection of succinylcholine in nonburn patients and electricburn patients, physical status 1 or 2 adopted by the American Society of Anesthesiologists. We compared two groups: Non-burn patient group(Group 1) as control, Electric burn patient group (Group 2) as experimental. The following results were obtained: 1) In non-burn patient group(Group 1) serum potassium concentration was slightly decreased in the 1st, 2nd, 3rd, 4th, 5th, 6th and 10th minute after succinylcholine injection compared with control, but nostatistical significance was noticed in this group. 2) In electric burn patient group (Group 2) serum potassium concentration was maximally increased compared with the controls. Statistical significance was noticed at the 2nd and 3rd minute after succinylcholine injection in this group.

Low-grade endometrial stromal sarcoma (LGESS) with intravascular extension is very rare, with only 26 cases having been reported. We experienced a case of LGESS with inferior vena cava (IVC) extension. A 60-year-old female presented with left leg edema. She had a history of total hysterectomy, and was diagnosed of leiomyoma at that time. On imaging study, tumor masses were located around both common iliac veins (CIV), and within the CIV and IVC. The pelvic masses on both side and IVC mass were resected, and then the patient received adjuvant hormonal therapy and radiotherapy over the remnant pelvic masses. LGESS with IVC extension is difficult to distinguish from intravascular leiomyomatosis. LGESS is a malignant disease and commonly recurs, even in early stages. Accurate diagnosis, complete resection, proper adjuvant therapy and close follow-up are very important.
