This study was aimed to clarify the effects of systemic kainic acid (KA) administration (10 mg/kg i.p.) on somatostatin containing neurons, and to examine the distribution of somatostain immunoreactive neurons in the cerebral cortex of the rats. Animals were sacrificed at three time points at the two, six, and ten days after the injection of KA. Thirty-six rats were observed by using the free-floating immunohistochemical method (modified ABC method). The results were as follows: 1) In the anterior and posterior cingulate cortex, somatostatin immunoreactive neurons were not observed in 2,6,10days after treatment of KA including control group except Cg 1 showing some somatostatin immunoreactive neurons in 10days and control groups. 2) In the insular cortex, somatostatin immunoreactive neurons also were not observed in any groups except AIV showing few somatostatin immunoreactive neurons in control group. 3) In the perirhinal cortex, few somatostatin immunoreactive neurons were observed in 2 days and 6 days groups. In control group, a number of somatostatin immunoreactive neurons observed. 4) A strong decrease of somatostatin immunoreactive neurons were observed in the frontal, arietal, temporal and occipital cortex 2 days after treatment of KA. Initially decreased somatostatin immunoreactive neurons had recovered to control 10 days after treatment. 5) Distribution of the somatostatin immunoreactive neurons was observed marked difference according to the cortical areas. Somatostatin immunoreactive neurons in isocortex were more increased in number than the allcotex by control study. The changes in somatostatin immunoreactive neurons after systemic treament of KA were marked in 2 days and 6 days, but these had recovered to control 10 days the treatment of KA. It suggested the normalization of the cerebral function 10 days after seizure. According to the cerebral cortex, the different distribution of somatostatin immunoreactive neurons in number was observed.

The treatment of acetabular fractures is composed of operative and conservative methods, however, they are still controversial. Generally, because the acetabular fracture involves the joint surface and one sequalae such as post-traumatic arthritis can follow treatment, therefore an accurate reduction and postoperative early mobilization to obtain the prevenation of joint stiffness and arthritis are required. In order to achieve these purposes, we have studied and done a comparative survey between conservative and operative treatment on 55 patients with acetabular fractures, who were treated at our department from Jan. 1982 to Dec. 1988. Results were obtained as follows. 1. The prevalent age was the third decade and the cause of injury was traffic accidents in the majority. 2. The most common type of fracture was a posterior wall by Letournel classification. 3. Satisfactory results of operative treatment were 76% and conservative treatment 47%. 4. The complications were post-traumatic arthritis, ectopic ossification, peroneal nerve palsy and skin infection. 5. In the majority of displaced acetabular fractures, ORIF was recommended.

Simple posterior hip dislocations requiring open reduction is very few and reported approximately 3% of all posterior hip dislocations and we have little comments of the various causes preventing or blocking a concentric reduction following traumatic posterior hip dislocation. In a review of eleven cases of posterior dislocation requiring open reduction, we divided two groups, one is a failed closed reduction group, the other is a nonconcentric reduction group. A concentric reduction was prevented from an inverted limbus or an osteocartilagenous loose body from acetabulum or femoral head.

BACKGROUND AND OBJECTIVES: Dual isotope myocardial SPECT, rest thallium-201/dipyridamole stress Tc-99m sestamibi is used to diagnose coronary artery disease. We examined predictive value of myocardial SPECT for the prognosis of patients having or suspected coronary artery disease. MATERIALS AND METHOD: We examined 692 patients referred for dipyridamole stress myocardial perfusion SPECT. Cardiac events (hard and soft events) were followed up with medical record review and telephone interview. Survival analysis and multivariate Cox proportional hazard model were used to find significant predictors and the incremental predictive value of myocardial SPECT. Patients with coronary angiography (n=246) were analyzed in separate group. RESULTS: There were 4 hard events and 3 soft events in 341 normal SPECT group (1.20%/yr). There were 5 hard events and 21 soft events in 351 abnormal SPECT group (4.69%/yr). Survival curve was separated between normal SPECT group and abnormal SPECT group (p<0.01). In univariate analysis, smoking, history of myocardial infarction, typical chest pain and SPECT findings were important variables. In multivariate analysis, SPECT result was the single most independent predictor. Large reversible perfusion abnormality predicted worse prognosis. In patients with coronary angiography, SPECT did not add statistically significant predictive value to the coronary angiography. CONCLUSION: Dipyridamole stress Tl-201/ MIBI dual isotope myocardial perfusion SPECT provided excellent prognostic information. Extent of reversible perfusion decrease was the independent predictor of future cardiac events.

A sepsis or multiple organ dysfunction occurs frequently in the intensive care unit and causes a significant number of mortality and morbidity. Somtimes polyneuropathy of varying severity occurs in association with a sepsis or critical illness. Since the clinical evaluation is often difficult, electrophysiologic studies are employed to reveal a definitive evidence for polyneuropathy. The purpose of this study was to investigate the frequency of polyneuropathy and to determine the electrophysiologic features of critically ill patients. The subjects were 23 patients between ages of 42 and 72 with a sepsis or systemic inflammatory response syndrome combinded with the multiple organ failure. The results revealed reductions in the amplitude of compound motor action potential and sensory nerve action potential, as the most marked abnormality. Needle EMG revealed the signs of denervation of limb muscles. Approximately 65.3% of adult patient with sepsis or multiple organ dysfunction has an axonal polyneuropathy. We suspect that the axonal polyneuropathy is related to the severity of multiple organ dysfunction.

Splenic anomalies are commonly associated with anomalies of cardiovascular system and of other organ systems. "Polysplenia" refers to the state in which the bulk of splenic tissue is divided into two and others more equal-sized splenic masses. We experienced a case of Polysplenia associated with complicated cardiovascular anomalies(Situs ambiguus, D-loop, normally related great arteries, interrupted inferior vena cave, bilateral superior vena cava, single atrium, common A-V canal, infundibular stenosis). We have presented this rare case and reviewed brief literatures.

PURPOSE: Functional MR imaging is the method of demonstrating changes in regional cerebral blood flow produced by sensory, motor, and any other tasks. Functional MR of visual cortex os performed as a patient stares a photic stimulation, so adaptable photic stimulation is necessary. The purpose of this study to evaluate whether the size of photic stimulation can affect the degree of visual cortex activation. MATERIALS AND METHODS: Functional MR imaging was performed in 5 volunteers with normal visual acuity. Photic stimulator was made by 39 light-emitting diodes on a plate ,operating at 8 Hz. The sizes of photic stimulator were full field, half field and focal central field. The MR imager was Siemens 1.5-T Magenton Vision system, using standard head coil. Functional MRI utilized EPI sequence (TR/TE=1.0/51. 0msec, matrix No.=98x128, slice thickness=8mm) with 3sets of 6 imaging during stimulation and 6 imaging during stimulation and 6 imaging during rest, all 36 scanning were obtained. Activated images were obtained using postprocessing software(statistical analysis by Z-zone, and these images were combined with T-1 weighted anatomical images. The activated signals were quantified by numbering the activated pixels, and activation index was obtained by dividing the pixel number of each stimulator size with the sum of the pixel number of 3 study using 3 kinds of stimulators. The correlation between the activation index and the stimulation size was analysed. RESULTS: Mean increase of signal intensities on the activation area using full field photic stimulator was about 9.6%. The activation index was greatest on full field. second on half field and smallest in focal central field in 4, The index of half field was greater than that of full field in 1. The ranges of activation index were full field 43-73%(mean 55%), half field 22-40%(mean 32%), and focal central field 5-24%(13%). CONCLUSION: The degree of visual cortex activation increases with the size of photic stimulator.

The current study evaluated DSM-IV psychiatric diagnoses and investigated the psychological characteristics of sexual offenders by using the Hypersexual Behavior Inventory(HBI), Sexual Addiction Screening Test (SAST), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Fifty male sexual offenders and 36 male healthy controls completed the psychiatric diagnosis and 30 of the 50 male sexual offenders completed the psychological tests listed above. Thirty-two of the 50 sexual offenders were patients with paraphilias, these sexual offenders had been admitted by the Ministry of Justice to the Institute for Forensic Psychiatry in Gongjui-si due to sexual violence. Participants displayed high lifetime rates of psychiatric disorders: 32 (64%) had paraphilias, 16 (32%) had depressive disorders, 10 (20%) had anxiety disorders, 9 (18%) had impulse control disorders, 6 (12%) had schizophrenia, 2 (4%) had bipolar disorders, and 16 (32%) had personality disorders or some other Axis II disorder. Scores for the sexual offenders were significantly higher both on the HBI and the SAST than the comparison group. Scores for the sexual offenders were also higher for the BDI and the BAI as compared to the control group, but this difference was not statistically significant. Results indicate that sexual offenders may have sexual addictions and be hypersexual. In addition to depressive and anxious psychopathologies, they also seem to have sexual psychopathologies. These results suggested that the psychopathology of sexual offenders may be different than that of a control group.
