OBJECTIVE: To investigate the effect of steroid administration on the apoptosis and heat shock protein 70 (HSP70) expression after exercise in the animal model of Duchenne muscular dystrophy. METHOD: We measured Bcl-2, BAX and HSP70 expression by western blotting. 20 control and 20 mdx mice were divided into free-living (n=10) and exercise (n=10) groups. Free-living and exercise groups were further divided into steroid-treated and sham-treated groups to evaluate the effect of steroid administration. RESULTS: Apoptosis was most prominent in the sham-treated exercise group, while apoptosis was significantly reduced in the steroid-treated exercise group. HSP70 expression was maximized in sham-treated exercise group, whereas steroid administration inhibited HSP70 expression after exercise in muscular dystrophy animal model. Exercise loading was found to cause severe apoptosis but steroid administration alleviated apoptotic damage in mdx mice. CONCLUSION: HSP70 expression was suppressed in the steroid-treated exercise group, which suggests steroid might have major preventive effect in exercise-induced apoptosis of muscular dystrophy animal model.

The population enjoying ski had increased since 1970's in Korea. Recently, that of snowboarders has increased rapidly among young population. Patterns of injuries are somewhat different between two sport activities. The most commonly injured region is knee among skiers and wrist among snowboarders. Head injury, spinal injury, and abdominal injury are not so common but a few serious injuries had been reported in Korea. To prevent or minimize injuries, proper pre-seasonal training including muscle strengthening, proper selection of equipments, and instruction for both sport technique and protection for safety are important. Also primary care for the injured as well as delivery system for seriously injured population should be established.

Rehabilitation is one of the five vital components of the healthcare system, along with prevention, promotion, treatment, and palliation. In Korea, inpatient rehabilitation service is inadequately supplied based on the low fee system for rehabilitation services and an absence of a standard for inpatient rehabilitation facility. Consequently, the length of hospital stays increases and the rate of successful post-rehabilitation return to the community is low. To provide intensive rehabilitation, US established ‘inpatient rehabilitation facility’ system and Japan established ‘restorative rehabilitation hospital system’. In 2020, a new accreditation system has been launched in South Korea with the aim to improve the country’s intensive inpatient rehabilitation services. This new system defines the standards of workforce management, facility, diagnostic category, comprehensive functional measure, onset and duration of inpatient rehabilitation, and fees for team conferences and social services for a successful return to the community. The system aims to achieve an effective and efficient inpatient rehabilitation system in Korea.

We report a case of a 53-year-old male with traumatic cervical spinal cord injury (SCI). He could not maintain a standing position because of painful spasticity in his lower limbs. A magnetic resonance imaging and electromyography indicated chronic lumbosacral radiculopathy, explaining his chronic low back pain before the injury. For diagnostic as well as therapeutic purposes, transforaminal epidural steroid injection (ESI) to the right L5 root was performed. After the intervention, the spasticity decreased and his ambulatory function improved. This case illustrates that lumbar radiculopathy concomitant with a cervical SCI can produce severe spasticity and it can be dramatically improved by ESI.

We report on operational and rehabilitation management, as well as the outcome, of a patient who with sustained spinal cord injury from a high velocity gunshot wound to the lumbar spine. More specifically, a patient with a gunshot wound to the spine is more likely to sustain a complete injury and have a poor prognosis. As such, there should be concerns regarding associated and extended injuries related to bullet fragmentation as well as the possibility of long-term sequelae.

Endoscopic sphincterotomy (E.S.T.) has relatively low complications and is the theraphy of choice in patients with common bile duct stones. It is also an useful technique for decompression of biliary tract obstruction. Thirty two cases of patients were selected according to opedrative risks: old age, severe jaundice and recurrent or retained bile duct stones after cholecystecomy from 1986 to 1988. The results were as follows, 1) In thirty two cases nf E.S.T., male to female ratio was 1:1.46. Most frequent age was older than 40 years. (male, 84.6%, female, 84.2%). 2) Out of thirty two cases, 20 cases (62.5% were under post clholecystectomy state, 12 eases (37.5%) were obstructive jaundice. 3) Spontaneous stone passage after E.S.T. was 81.3% (26 cases), and total stone remoral rate was 87.5% (28 cases), 4) Complications of E.S.T. were noted in three cases. In the two cases of bleeding, it was spontaneously improved and a case of acute pancreatitis was treated by medical care.

The diagnostic value of nerve conduction study of spinal stenosis is far limited due to its deeply located lesion and its very short length of diseased nerve compared to the relatively long length of total conduction distance. Recently it became possible to stimulate the deep sited spinal nerve roots non-invasively with magnetic stimulation. The authors made a new method to calculate the motor nerve conduction time of lumbar spinal root using magnetic stimulation and planned to verify the delayed conduction time in patients with spinal stenosis who didn't show any abnormalities in the conventional electrophysiologic studies(peripheral nerve conduction velocity, F-wave and needle EMG). Three steps of magnetic stimulation were applied to vertex(transcortical stimulation), T12 spinous process(thoracic stimulation) and S1 spinous process(sacral stimulation), and three channel recording were performed at rectus abdominis(RA), right and left abductor hallucis(AH) simultaneously. Central motor conduction time(CMCT) was calculated by time difference between vertex and spinal stimulation at RA and AH. Lumbar-segment motor conduction time(LMCT) was defined as conduction time by subtracting CMCT of RA from CMCT of AH. The results as follows; LMCT was delayed in the group of patients with spinal stenosis(5.36+/-2.11 msec) compared to the normal control group(4.05+/-1.23 msec), but the range of LMCT was not quite different individually. Dividing the patients group into multi-level and single-level spinal stenosis group, LMCT in the multi-level spinal stenosis group was 6.12+/-1.95 msec which was significantly different from that of single-level(4.48+/-1.96 msec). The authors conclude that LMCT, the short segmental motor nerve conduction study of lumbosacral nerve root, is useful to confirm the entrapment of spinal nerve root across the lumbosacral spinal canal and is also non- invasive, simple and applicable to any other spinal nerve roots.
