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.

A 3.4 year-old rhesus macaque weighing 4.5 kg, was suffering from anorexia, acute mucous and bloody diarrhea. On physical examination, the monkey showed a loss of activity, hunched posture, abdominal pain, dehydration, mild gingivitis and unclean anus with discharge. Whole blood was collected for the examination of electrolytes, hematology and serum chemistry; fresh stool was also collected for bacterial culture. Blood profiles showed leukocytosis (14.5 K/microL) and neutrophilia (11.0 K/microL) on complete blood cell count and imbalanced electrolytes associated with diarrhea. As a result of bacterial culture, Shigella flexneri was identified through Mac/SS, IMVIC test, TCBS and VITEK II. Based on these results, this monkey was diagnosed as having acute enteritis caused by Shigella flexneri. Treatment was performed with enrofloxacin prior to the isolation of Shigella flexneri to prevent the transmission of disease. Fortunately, mucus and bloody diarrhea did not persist and general conditions fully recovered. Our results show that the use of enrofloxacin is effective in controlling Shigella flexneri infection in newly acquired rhesus monkeys.

Even though the value of computed tomography (CT) used to detect the colon carcinoma with minimal invasion is limited, its usefulnes sin the evaluation of the extent of disease such as hepatic metastasis or distant lymph node invasion has been emphasized. To examine the role of CT in the evaluation of colon carcinoma, CT scans obtained during the past 2 years in 56 patients with surgically proven colon carcinoma were reviewed and the findings correlated with pathologic results. The sensitivity and accuracy of CT for pericolic fat infiltration were 86, 58 and 80% respectively. Those of regional node were 60, 83 and 75% and distant node 67, 100 and 95%. Liver metastases showed sensitivity, specificity and accuracy of 83, 98, 96% and peritoneal metastases 67, 94 and 89% respectively. CT detected local invasion with fair degree of accuracy but the true value of CT lie in the detection of distant invasions such as liver and distant lymph node metastases thereby leading to preclusion of unnecessary procedures and implementation of appropriate precedures.

Klinefelter's syndrome (KFS) is a gonosomal aberration disease that occurs in males, and is characterized by 47, XXY karyotype, hypogonadism and a lack of secondary sexual characteristics. A potential link between this hormonally deficient syndrome and autoimmune disease, particularly systemic lupus erythematosus (SLE), has been reported. On the other hand, KFS is rarely reported to be accompanied by rheumatoid arthritis (RA), and there are no Korean cases reported. We report the first Korean case of a KFS patient with sero-positive RA and discuss the role of the pathogenesis of RA with KFS.

BACKGROUND: In the western hemisphere, resistance to activated protein C (APCR) is the most common risk factor for venous thromboembolic disease. A one-point mutation in the coagulation factor V that renders it APCR is found in more than 90% of patients with APC-resistant venous thrombosis. In Hispanic and Caucasian patients with arterial ischemic stroke, the prevalence of APC-R is approximately 10%. To determine the prevalence of APC resistance and its causative factor V mutation (Arg 506 Gln) in Koreans, we screened a group of Korean ischemic stroke patients. METHODS: We evaluated 60 Korean patients with arterial ischemic stroke diagnosed by either magnetic resonance neu-roimaging, conventional angiogram, or both, after 2 weeks of symptom onset. The mean age of the subjects was 59.2 years (13-82 years). APC resistance was expressed as a ratio of the activated partial thromboplastin time (aPTT) with and without adding APC to the subject's plasma. The presence of the factor V Leiden (Arg 506 Gln) mutation was determined by a direct polymerase chain reaction-based assay on peripheral blood leukocytes. RESULTS: Only one patient (n=1/60, 1.6%) had APC resistance and none were found to have the factor V Leiden (Arg 506 Gln) mutation. CONCLUSIONS: APCR and the factor V Leiden mutation do not seem to be a significant genetic risk factor for arterial ischemic stroke in Koreans.

Autologous fat injection for soft tissue augmentation in the face has been claimed to be a safe procedure. However, there are several case reports where patients suffered from various neurologic deficits following fat injections. We report a patient who suffered from cerebral infarction after fat injections into the face. We assume that fragments of fat reach cerebral arteries by reversed flow through the branches of the carotid arteries caused by local increase in pressure in highly vascularized tissue.

Although the liver is the most common site for pancreatic islet transplantation, it is not optimal. We compared kidney, liver, muscle, and omentum as transplantation sites with regard to operative feasibility, and the efficiency of implantation and glycemic control. Islets from C57BL/6 mice were transplanted into diabetic syngeneic recipients. The mean operative time and mortality were measured to assess feasibility. To assess implantation efficiency, the marginal mass required to cure diabetes and the mean time taken to achieve normoglycemia were measured. A glucose tolerance test was performed to assess glycemic control efficiency. The data are listed in the order of the kidney, liver, muscle, and omentum, respectively. The mean mortality rate was 6.7, 20.0, 7.1, and 12.5%; the mean operative time was 10.2, 27.4, 11.2, and 19.8 min; the marginal islet mass was 100, 600, 600, and 200 islet equivalence units and the mean time to reach euglycemia was 3.0, 15.1, 26.6, and 13.9 days. The glucose kinetics of omental pouch islets was the most similar to controls. Thus, a strategic approach is required for deciding on the best transplantation recipient sites after considering donor sources and islet volume. Alternatives can be chosen based on safety or efficacy.

Traditionally, monocular parital oculomotor pareses are localized to the cavernous sinus or retro-orbital region and are usually caused by diabetes mellitus, aneurysms of the internal carotid artery, inflammation by vrial infection or autoimmune diseases, neuropathy or neuromuscular disesases. Although rare, the monocular partial oculomotor paresis also can be caused by lesions of ventral midbrain because of their particular topographic arrangement. We present 2 cases with fascicular oculomotor nerve involvement from midbrain lesion, who presented with monocular partial ocu-lomotor nerve palsy. One patient showed partial ptosis and slow saccadic movement of the right eye. The other patient showed parital ptosis and limitation of adduction and elevation in the left eye. They had normal pupil size and light reflexes. Brain magnetic resonance images showed focal infarction in the fascicular portion of the oculomotor nerve.
