This is a case report of spinal cord abscess in pork carcasses. We have detected 7 cases with spinal cord abscesses in abattoir from January to October 2008. It may occur from either direct extension or hematogenos infection. Four cases were presumed by hematogenous infection because of no external wound, and 3 may be caused by direct extension. The infection is a result of external wound in 3 pigs and is a result of hematogenous spread in 4 pigs. The incidence rate of spinal cord abscess in sows is higher than that in pigs.

The clinical investigation was done in the 42 patients with bilateral vocal cord palsy who visited the otorhinolaryngologic department of the Yongdong Severance Hospital during the 10-year period between August 1986 to August 1996. On the sex and age distribution, the ratio of male to female patients was 2.8 : 1 and the age was evenly distributed and average was 46 years old. Of their chief complaints, dyspnea was the most common symptom. Among the position of the paralyzed vocal cords, paramedian position was most common. The most common causes of the bilateral vocal cord palsy was idiopathic Other causes include iatrogenic, prolonged intubation, head ＆ neck trauma, brain tumor, Myasthenia Gravis, and mediastinitis. Our treament results were as follows. Recovery rate of idiopathic bilateral vocal cord palsy was 77.7% and recovery period after bilateral vocal cord palsy was shortened remarkedly after use with steroid. We performed laser arytenoidectomy in patients with irreversible idiopathic vocal cord palsy, neural injury, and cricoarytenoid joint fixation. Decannualtion was possible to be carried out in 86% of the patients and none of complication except for 1 case of aspiration developed. Thus we concluded that it was meaningful surgical treatment of bilateral vocal cord palsy.

The purpose of this study was to evaluate the folate nutritional status of Korean pregnant women and to investigate the relation between folate levels of maternal-umbilical cord blood, placenta tissue, and pregnancy outcomes. The study subjects consisted of 25 pregnant women who have had normal term deliveries. Dietary folate intakes of the pregnants were estimated by semi quantitative frequency questionnaire and the serum and placenta tissue folate level was measured by microbiological analysis. The total folate intakes of the pregnant women was 655.6 ${\mu}$g/d, which was 131.1% of the Korean RDA for pregnants. Maternal serum folate level was 16.18ng/ml, which was significantly lower than that of umbilical cord blood (34.98ng/ml, p<0.05). Mean folate concentration of the placental tissue was 998.0ng/ml, which was the highest compared to maternal and umbilical cord serum level. Umbilical cord serum folate level and placental tissue folate level were highly influenced by maternal serum folate level. The umbilical cord folate levels of the infant group whose birth weight was higher than 3500g were significantly higher than the group whose birth weight was less than 3500g (p<0.05). The placental folate level was significantly higher in maternal group who showed desirable weight gain during pregnancy (11 - 14kg). In conclusion, the birth weigt was related to the umbilical cord folate level and the maternal weight gain was affected by the placental folate level.

Purpose: This study investigates the influence of elastic resistance exercise using proprioceptive neuromuscular facilitation (PNF) on the daily activities of a patient with incomplete spinal cord injury. The result will be proposed as background data for effective intervention in a patient with incomplete spinal cord injury. Methods: The target subject was a patient with incomplete spinal cord injury to the cervical cord (C6). Elastic resistance exercise based on PNF was performed for 30 min daily, five times a week, for eight weeks. The ASIS motor scale was applied to test the muscular strength of the upper limb, and the spinal cord independence measure II (SCIM II) was used to evaluate the capacity of daily activity. Results: By applying elastic resistance exercise based on PNF, the muscular strength of the upper limb increased and the performance of daily activity improved. Conclusion: Because elastic resistance exercise based on PNF positively influences the ASIA motor scale and SCIM II of the patient with incomplete spinal cord injury. It can be used for training programs to improve the capacity of daily activity of the patient.

The failure of injured axons to regenerate in the mature central nervous system (CNS) has devastating consequences for victims of spinal cord injury (SCI). Traditional strategies to treat spinal cord injured people by using drug therapy and assisting devices that can not help them to recover fully various vital functions of the spinal cord. Many researches have been focused on accomplishing re-growth and reconnection of the severed axons in the injured region. Using cell transplantation to promote neural survival or growth has had modest success in allowing injured neurons to re-grow through the area of the lesion. Strategies for successful regeneration will require tissue engineering approach. In order to persuade sufficient axons to regenerate across the lesion to bring back substantial neurological function, it is necessary to construct an efficient biocompatible bridge (cell-free or implanted with different cell lines as hybrid implant) through the injured area over which axons can grow. Therefore, in this paper, spinal cord and its injury, different strategies to help regeneration of an injured spinal cord are reviewed. In addition, different aspects of designing a biocompatible bridge and its applications and challenges surrounding these issues are also addressed. This knowledge is very important for the development and optimalization of therapies to repair the injured spinal cord.

This study was out to evaluate the folate nutritional status of Korean pregnant women and to investigate the relationship between serum folate levels of maternal-umbilical cord blood and pregnancy outcomes. Folate intakes of the pregnants was estimated by dietary folate intakes obtained from semiquantitative frequency questionnaire and supplementary folate intakes. The serum folate levels in both maternal blood and umbilical cord of 29 pregnant women at delivery and 13 nonpregnant controls were measured by redioimmunoassay. The total folate intakes(dietary and supplementary)of the pregnant women was 465. 4$\mu\textrm{g}$/d which was 93% of the Korean RDA for folate. Maternal mean serum folate levels of the pregnants was 6.1$\mu\textrm{g}$/ml, significantly lower than that of nonpregnant women(8.9ng/ml). Mean serumfolate level of umbilical cord blood was 14.2ng/ml, which was 2.3 folds higher than that of maternal blood. This finding indicates that the uptake of folate in the fetus may be due to an active placental transport mechanism. Maternal serum folate level correlated positively with that of umbilical cord blood, showing that folate concentration of umbilical cord blood is affected by maternal status. There was no significant correlation between the serum folate levels in maternal-umbilical cord blood and the pregnancy outcomes.(Korean J Nutrition 33(8) : 840-847, 2000)

This study aims to the influenced factor analysis of spinal cord independence measure(SCIM), on walking velocity, walking endurance, time up & go(TUG), and subject characteristics. The subject of this study were 12 persons with incomplete spinal cord injury(ASIA C, D). All subject ambulatory with or without an assistive device. All participants were assessed on SCIM(score), walking velocity(m/s), walking endurance(m) and TUG(s). The data were analyzed using independent t-test and stepwise multiple regression. The results revealed that no statistical difference was noted in subject characteristics among SCIM, walking velocity, walking endurance, TUG(p>0.5). The independence score, breathing-sphincter control and ambulation were important factors in TUG(31.4%). The results suggest that SCIM may be an inappropriate assessment tool to predict gait ability of patient with incomplete spinal cord injury. Further study about gait speed, gait endurance and TUG by change of SCIM is needed using to patient of incomplete spinal cord injury.

In order to detect and monitor the broken cords of steel-cord belt from being damaged by impact of large lump of materials and the corrosion of steel cord, we developed a non-contact magnetic coil detection system. This measures the deterioration of reinforcing cables in steel cord conveyor belt which transport the ores in raw material plant. In this research, magnetic coil sensor of broken-cord detection system has exciting part and sensing part. The broken-cord detection system is operated by supplying a transmitter coil with electric power to generate magnetic field, and then the change of induced voltage is detected in each receiver coils due to resultant magnetic flux effected by the broken steel cords at the inside of the conveyor belt. By the informations such as the position and size of the broken steel cords obtained by SCBMS(Steel Cord Belt Monitoring System), it is expected that not only the span of belt life will be lengthened, but also this system can enable operators to plan scheduled maintenance and prevent the enlargement of damaged parts in steel cord belt at an early stage

Iron deficiency anemia in pregnant women has been of great concern because of its negative effects on the outcomes of pregnancy. Much of evidence has shown that there are associations between pregnancy outcomes and maternal iron status. Maternal iron status might affect pregnancy outcomes through the iron status of the cord blood. In this study, we divided 91 subjects into two groups : the anemic and the normal groups. The groups were classified according to their hemoglobin(Hb) and hematocrit(Hct) values of the maternal blood in the third trimester of the pregnancies. We determined the parameters for the iron status of the cord blood and then analyzed the correlations between these parameters and the pregnancy outcomes. Mothers in the anemic group had a significantly higher parity number and a lower dietary score as well as a shorter duration of iron supplements consumed compared to those in the normal group. Maternal Hb values in the third trimester had positive correlations with the infant's head and chest circumferences, and the Hct values related positively to the infant's chest circumferences. On the other hand, Hb concentrations of the cord blood had positive correlations with the infant's height and head and chest circumferences. The Hct values of the cord blood had positive correlations with gestational periods and the cord lengths. These results suggest that the maternal iron status might influence fetal development through the iron status of the cord blood.
