STUDY DESIGN: Thirteen patients with cervical interlocked facets dislocation in whom closed reduction by skull traction was failed were evaluated about the patterns of ruptured disc fragment. Objects : To evaluate the causes of failure at closed reduction, and the relation between ruptured discs and interlocked facets, and the treatment results through an anterior approach. SUMMARY OF LITERATURE REVIEW: In traumatic dislocation of the cervical facet joints, spinal cord or nerve roots injury associated with the ruptured disc fragment has been reported. However, there is few report evaluating the patterns of ruptured disc fragment as a cause of reduction failure. MATERIALS AND METHODS: Between 1988 and 1997, thirteen patients were treated by anterior fusion with plate after complete removal of the intervertebral disc through anterior approach and reduction of interlocked facets by O1iveira method. They have been followed for an average of 36 months(range : 12-96 months). The interlocking was bilateral in seven cases and unilateral in six cases. We assessed the types of ruptured disc fragment by preoperative MRI and CT and the clinical and radiological results. RESULTS: Ruptured disc fragment was found in all thirteen patients with interlocked facets dislocation. The patterns of ruptured discs were within the uncovertebral joints in 5 cases, posterioly under the posterior longitudinal ligament in 3 cases, anteriorly under intact anterior longitudinal ligament in 3 cases and combined under the anterior and posterior longitudinal ligament in 2 cases. The displacement of ruptured disc fragment were seemed to be the cause of failure in closed reduction. CONCLUSIONS: Intervertebral disc injury should be evaluated carefully with MRI and CT in the lower cervical interlocked facet dislocations before trial of reduction or decision makings of treatment.

OBJECTIVE: To determine whether hysterectomy by the vaginal route is safe and feasible in patients with previous pelvic operation. METHODS: A retrospective study of the records of Hallym University Hospistal patients who underwent vaginal hysterectomy performed by the senior author. Between January 1990 and January 1997, 212 patients who had previous pelvic operation were studied with special reference to operative difficulties, previous operation type, intraoperative complications, surgical time, hospital stay. RESULTS: 1. Patients characteristics was that ; The average age was 44.5+/-6.6 years old, the average parity was 2.3 , the average stay of hospitalization was 7.5+/-0.89 days, the frequency of Morcellation was in 24.5%, the average surgical time including associated procedure was 82+/-16.2 minutes, the average uterine weight was 164+/-85.1gm. 2. The most common previous pelvic operation was cesarean section(95 cases). 3. The most common indication was uterine myoma(51.9%). 4. Surgical technique used to gain access to the pouch of Douglas was done anteriorly; 52 patients of previous cesarean section(24.5%) and 112 patients of others operation(52.8%) were easily opened by blunt dissection, 43 patients of previous cesarean section(20.3%) and 5 patients of others operation(2.4%) were required sharp dissection. posterioly ; 190 patients(89.6%) were easily opened by blunt dissection, 22 patients(10.4%) were required sharp dissection. 5. Significant complications were bladder injury(1 case) , postoperative transfusion due to bleeding(6 cases). No cases of postoperative laparotomy was done and other minor compications were fever(15 cases), bladder retention(11 cases), others. CONCLUSIONS: It was possible to perform vaginal hysterectomy safely in patients with previous pelvic operation. Vaginal hysterectomy remains the method of choice for removal of the uterus of the previous pelvic operations in the absence of other contraindications.

The soleal line in 115 (left; 61, right; 54) cases of tibiae was studied morphometrically by the method of Mysorekar and Nandedkar. 1. The soleal line showed a uniform character throughout in 26 cases and a mixed characters in 89 cases. The bones showing uniform character were seen generally as a lineal line or wide line. 2. The soleal line having mixed characters divided into three parts. In the upper and middle thirds, the major type of line was wide line. In the lower third, the line was commonly seen as a lineal line. In about 12% of the bones examined the line was seen as a groove, particularly in the middle and lower thirds. 3. The soleal line commenced 1-2cm below the fibular facet In about 61% of cases. 4. The length of the soleal line was 10.5cm, and the ratio to that of the tibia was about 30%. The results of this study provide the characters of the soleal tne of the tibia in Korean. The soleal line, unlike the textbook description, generally shows mixed characters of a line.

This study was undertaken to investigate the morphologic changes following flushing, preservation and reperfusion procedures in a canine lung allotransplantation model. Donor lungs were flushed with modified Euro-Collins (MEC) solution, low potassium dextran glucose (LPDG) solution or University of Wisconsin (UW) solution, then stored at 10oC for 20 hours. Light microscopic and electron microscopic features of the lungs were examined after flushing, preservation and 2 hours after reperfusion. After flushing light microscopy showed focal mild alveolar collapse and interstitial edema. After preservation the lung tissue showed multiple foci of alveolar collapse, consolidation, and alveolar epithelial cell damage. After reperfusion the lung tissue showed diffuse alveolar collapse, consolidation and many destroyed cellular debris in the alveolar lumina. After flushing electron microscopy showed focal alveolar collapse and mild swelling of type I epithelial cells. After preservation both type I epithelial cells and endothelial cells were swollen and destroyed focally. Some type I epithelial cells were detached from the basal lamina. The endothelial cells showed luminal protrusion of tactile-like structure and vacuoles of the cytoplasm. After reperfusion the lung tissue showed fibrin material in the alveoli, prominent type I epithelial cell swelling with fragmented cytoplasmic debris and marked endothelial cell swelling with vacuoles or tactile-like projections. The alveolar macrophages showed active phagocytosis. After preservation scanning electron microscopic examination of the pulmonary arteries showed multiple patchy areas of swelling or conglomerated lesions in the inner surface of the pulmonary arteries. In conclusion, the ultrastructural changes associated with flushing were mild in severity, the donor lungs were injured during the preservation, and further damage occurred during the reperfusion.

Severe limitation of knee motion is a complication of operative procedures or trauma about the knee. Physical therapy and occasionally manipulation of knee with anesthesia may improve results when performed soon after the onset of motion limitation. When performed later, these have been proven less useful. This is a review of 15 patients who had severe limitation of knee motion following open operative procedures or trauma about knee and were treated by percutaneous release of adhesions under arthroscopic control. There were eleven males and four females, ranging in age from 23-67years(mean 38 years). The interval between the last open operative procedure or trauma and arthroscopic adhesiolysis ranged from three and half months to four years(mean 11.5 months). The interval between arthroscopic adhesiolysis and final follow-up evaluation ranged from 6 months to 3 years(mean 1.5 years). Average preoperative knee motion was 38.2 degrees. After arthroscopic adhesiolysis, maximum knee motion under anesthesia was 120.3 degrees and average final motion at follow-up was 101.2 degrees. The results of treatment of treatment of Tbc knee sequalae with secondary osteoarthritis and pyogenic arthritis were less favorable for motion improvement. Arthroscopic adhesiolysis seems to be a useful method of treatment in knee ankylosis. Morbidity was low, complications were few and the duration of hospital stay was short.

OBJECTIVES: To investigate the effects of (-)-3-PPP(0.5, 2, and 10mg/kg, s.c.) and haloperidol(0.1, 0.5, and 2mg/kg, s.c.) on the extracellular dopamine concentrations, and the effect of pretreatment with (-)-3-PPP(2mg/kg) on the haloperidol(2mg/kg)-induced extracellular dopamine concentrations in the nucleus accumbens(NAS) of free moving rats. METHODS: Dopamine levels in dialysate were determined with high pressure liquid chromatography(HPLC) with electrochemical detection(ECD). RESULTS: (1) (-)-3-PPP had dual actions depending on the doses : at 2mg/kg, it decreased and at 10mg/kg, increased extracellular dopamine concentrations ; (2) haloperidol at all doses increased dopamine levels with higher dose having a greater icrease ; and (3) pretreatment of (-)-3-PPP reduced the increase in dopamine levels elicited by acute treatment with haloperidol. CONCLUSIONS: These findings suggest that pretreatment of (-)-3-PPP in low dose could accelerate the onset of therapeutic effect of haloperidol by diminishing the haloperidol-induced dopamine release in the limbic system.

OBJECT: It is reported that the effect of antipsychotics on the extracellular dopamine levels in the prefrontal cortex is related to the their effect on the negative symptoms. Therefore, we investigated the acute and chronic effects of olanzapine and risperidone on the extracellular dopamine concentrations in the prefrontal cortex of rat. Samples were obtained using in vivo brain microdialysis. METHOD: Dopamine levels in the samples were measured by high pressure liquid chromatography with electrochemical detection. RESULTS: 1) Both the acute treatment of olanzapine and risperidone increased the extracellular dopamine concentrations in the prefrontal cortex, dose-dependently. 2) There was a no significant difference in the maximal change of the extracellular dopamine concentrations in the prefrontal cortex induced by the acute treatment of olanzapine and risperidone. 3) Both the chronic treatment of olanzapine and risperidone also increased the extracellular dopamine concentrations in the prefrontal cortex, but they showed the tolerance effect that the degree of increase was smaller than that of the acute treatment. 4) As for the maximal changes of the extracellular dopamine concentrations in the prefrontal cortex induced by the chronic treatment of olanzapine and risperidone, the effect of the former was greater than that of the latter. CONCLUSION: These results suggest that the effects of olanzapine and risperidone on the negative symptoms are related to the increased extracellular dopamine concentrations in the prefrontal cortex induced by these drugs.

As a series of systematic classification of paramphistomes, the worms in the rumen and reticulum were collected on 214 Korean cattle slaughtered at Jeonju abattoir from January 1986 to April 1987 and were classified by means of morphology. Afterwards, the karyotype of Paramphistomum cervi (Zeder, 1790) was detected by means of modified air-drying method from germ cells of the worms. The results were summarized as follows: In the chromosome number of 254 P. cervi, the haploid cell was n=9 and the diploid 2n=18. The meiotic divisions were observed frequently; 1,924 haploid and 32 diploid cells were reliable. Nine pairs of mitotic chromosomes were homologous in the metaphase stage, and the chromosomes were composed of five medium-sized metacentrics (m), subtelocentrics (st) or submetacentrics (sm) and four small-sized subtelocentrics(st) or submetacentrics(sm). Meiotic metaphase was composed of five medium and four small chromosomes in size. As a series of C-banding method, C-band was showed in centromeric region from all of the haploid germ cells. Whereas chromosome No. 3 and 5 included heterochromatin on the tip region, chromosome No. 4 on the distal region and No. 6 proximal region. And chromosomes No. 2 and 8 showed a remarkable C-band distinguished from other chromosomes.

BACKGROUNDS: Today, tuberculosis cannot only be cured medically, but also controlled by public health. Despite the overall worldwide decline in tuberculosis, the disease continues to be a significant problem among developing countries and in the slums of large cities in some industrialized countries. Particularly, this communicable disease has come into the public health spotlight because of its resurgence in the 1990's Our country has been operating the Korean National Tuberculosis Control Program since 1962, focusing around public health centers. Therefore, this study aims to compare the effectiveness of tuberculosis control activities, one of the major public health activities in Korea, by producing indexes, such as the yearly registration rate per 100,000 population and treatment compliance of tuberculosis on in small areas (communities). METHODS: This work was accomplished by constructing a time-series analytic model using data from "1980~2000 : the Yearly Statistical Report" with patient registry data of 234 City. County. District public health centers and by identifying the factors influencing the tuberculosis indexes. RESULTS: The trends of pulmonary tuberculosis positive point prevalence and pulmonary tuberculosis negative point prevalence on X-ray screening have declined steadily, beginning in 1981 and continuing to 1998 by region (city. county. district). Although the tuberculosis mortality rate steadily shows a declining trend by year and region, but Korea still ranks first among 29 OECD countries in 1998, with a tuberculosis mortality rate of 7.1 per 100,000 persons, according to the time-series analysis for fatal diseases. CONCLUSION: The results of the study will form the fundamental basis of future health care planning and the Korean Tuberculosis Surveillance System on 2000. Since the implementation of local autonomy through the Local Health Act of 1995. it has now become vital for each city. county. district public health centers to determine its own priorities for relevant health care management, including budget allocation and program goals.
