This study was carried out to clarify the effect of dietary calcium, casein, and suet on the accumulation of cadmium in mice. It was performed for 30 days, from April 11 to May 10 1988. 90 mice were divided into 4 experimental groups and control group with 6 mice each dietary group, and measured survival rate, body weight, and weight ratio of organ to body. The contents of cadmium in liver, kidney, spleen, muscle and skin with hair, and faces were analyzed by atomic absorption spectrophotometer after sacrifice by anesthesia. After 30 days, the survival rate of control group was 100%, but 66.7% in group IV(basal+Cd+Ca) with single dose of 100 microgram cadmium and with free-intake of water containing 50ppm cadmium, and group V(basal diet+Cd+suet) with free-intake of water containing 50ppm cadmium. The rate of weight gain in the case of single dose of 100 microgram cadmium was highest in group IV as 42.3% and lowest in group V as 26.0%, whereas in the cases of free intake group IV was highest as 24.0% and group II(basal diet+Cd) was lowest as 11.6%. The body weight, in the case of single dose of 100 microgram cadmium showed no increase until 5th day after acute poisoning. But in the case of free intake group, it showed very increase through all the breeding period. The weight ratio of organ to body were lowest in the liver of group II in both occasions. The most of cadmium administered were excreted through feces within 2 days after single dose of 100 microgram cadmium. The contents of cadmium in each group were significantly higher than those of control group. In the liver, kidney, spleen and muscle, group II showed the highest level in both occasions of 100 microgram single dose and free intake of water containing 50ppm cadmium. In the skin with hair, group II of the occasion with single dose of 100 microgram and group V with free intake showed the highest level. And the contents of cadmium in tissue were markedly higher in the occasion of free intake of water containing 50ppm cadmium. From the above results I would conclude that the addition of casein and calcium are effective in the inhibition of intension absorption of cadmium esp. by calcium.

This study was designed to validate the usefulness of the near point of convergence(NPC)test in determination of dominant & non-domnant eyes in intermittent exotropia patients. We performed NPC test in 36 intermittent exotrpic patients, and then, determined the non-dominant eye which deviated outward beyond the NPC. The dominant eyes determined by the NPC were compared to those that were determined by amblyopia, sensory fusion and photophobia. Best corrected visual acuity was used to divide patients into two groups : 26 patients without amblyopia, and 10 with amblyopia. Among the amblyopia group, if the eyes with better visual acuity were taken as dominant eyes, then eight(80%)cases were identical with the NPC test and two(20%)cases were different. Ten patients had sensory anomaly, and among then, nine(90%)cases were identical with the NPC test and one(10%)case was different. Twenty six(64%)patients had photophobia in one eye and all(100%)cases were identical with the NPC test. In intermittent exotropia, determination of dominant eye by the NPC test showed high coincidence with other tests. Therefore, we suggest that the NPC test is an easy and accurate method in determining either the dominant or non-dominant eye for surgery.

Journal of the Korean Geriatrics Society 2001;5(4):285-301
Radiofrequcy(RF) treatment has a long history, more than hundred years, for the management of chronic intractable pain of various causes. With better understanding of pain mechanism and advancement of technology, along with previous valuable experience, a simpler and safer method of delivering RF thermo coagulation to ideal sites are now available that can be expected to provide more beneficial effects to these patients with chronic disabling pain. This type of treatment will be especially helpful in aged in whom surgery is often contraindicated or highly risky due to medical problems. Here, using up-to-dated, evidence based knowledge and personal experience, authors have tried to introduce briefly the history and basic mechanism of RF technique and various clinical situations where this type of therapy is currently known to be indicated or effective in providing substantial pain relief. In summary, the RF thermocoagulation is proven to be effective way of providing significant pain relief in many chronic refractory pain states with numerous advantages such as minimal invasive, quantitative lesioning with temperature-controlled, well-circumscription of lesions, simplicity and feasibility of procedure, and most of all safety and cost-effectiveness. When it is selected based on careful investigation on type and cause of pain it can be expected to provide relatively long duration of pain relief and also to help to recover functional disabilities from such pain. However, judicious use is warranted because some painful conditions are known to be ineffective or contraindicated from this type of therapy and because there are possible serious complications, although very few. Use of latest technique of pulsed, high-frequency, low-temperatured thermocoagulation will possibly bring hope and new insights in the management of chronic intractable pain of neuropathic in nature. Further research and experience will be required before justifying this type of therapy in appling broader and more challenging situations.

5.Pharmacologic Management of Chronic Pain.
The Korean Journal of Pain 2010;23(2):99-108
Chronic pain is a multifactorial condition with both physical and psychological symptoms, and it affects around 20% of the population in the developed world. In spite of outstanding advances in pain management over the past decades, chronic pain remains a significant problem. This article provides a mechanism- and evidence-based approach to improve the outcome for pharmacologic management of chronic pain. The usual approach to treat mild to moderate pain is to start with a nonopioid analgesic. If this is inadequate, and if there is an element of sleep deprivation, then it is reasonable to add an antidepressant with analgesic qualities. If there is a component of neuropathic pain or fibromyalgia, then a trial with one of the gabapentinoids is appropriate. If these steps are inadequate, then an opioid analgesic may be added. For moderate to severe pain, one would initiate an earlier trial of a long term opioid. Skeletal muscle relaxants and topicals may also be appropriate as single agents or in combination. Meanwhile, the steps of pharmacologic treatments for neuropathic pain include (1) certain antidepressants (tricyclic antidepressants, serotonin and norepinephrine reuptake inhibitors), calcium channel alpha2-delta ligands (gabapentin and pregabalin) and topical lidocaine, (2) opioid analgesics and tramadol (for first-line use in selected clinical circumstances) and (3) certain other antidepressant and antiepileptic medications (topical capsaicin, mexiletine, and N-methyl-d-aspartate receptor antagonists). It is essential to have a thorough understanding about the different pain mechanisms of chronic pain and evidence-based multi-mechanistic treatment. It is also essential to increase the individualization of treatment.

6.A survey of the Types of Burns in Children and Mother's Preventive Attitudes to, and Knowledge of Burns.
Korean Journal of Child Health Nursing 1998;4(1):97-104
Burns is children result in the loss of precious life, or if the child survives, in much suffering from physical, emotional, social, and economic problems. These burn accidents to children happen in the bustle of family life and frequently without any warning. With this background information, this study was designed to identity types of burns in children and mother's attitudes towards, and knowledge of burn prevention, in order, to not only, in still a safety consciousness regarding the seriousness of burn accidents and the strengthening prevention, but also as basic data towards the development of an educational program aimed at prevention. From May 1 to May 25 in 1997, data were collected from the mothers of children attending five day care centers and kindergartens located in Seoul, which had been selected for the study. The tools used for the study, which were developed by the researchers, surveyed the type of burns suffered by children, mother's knowledge of burns and attitudes toward burn accidents. The data were analyzed through real numbers percentages and analysis was done using SPSS computer programs. The results of the study show that the most frequent type of burn accidents were those caused by hot water(55.4%) and these were frequently related to everyday habits that easily lead to danger. Further, the first aid treatment following a burn was weak. The majority of the mothers had not instructed their children on who to contact in the cape of a fire, first aid for burns, or how to take escape in the case of a fire. This left the children in a defenseless position in case of a fire. The mothers showed a lack knowledge, on what to do when a blaze is discovered, how to put out a fire, first aid for burns, escaping from a fire and appropriate water temperature, in that 50% of the time they answered incorrectly. From this study a prevention program, HIPP(Home Injury Prevention Program) could be developed that includes fire prevention habits and first aid for burns. This program can be used with kindergarten and elementary school children for group education fire prevention and can be used as a foundation for construction of a system of facilities and equipment to prevent fires and also prevent injury from fires.

7.Multiple Chorioangiomas of Placenta: A case report associated with repeated abortions and intrauterine fetal death.
Korean Journal of Pathology 1985;19(1):131-135
Chorioangioma is the most common primary tumor of the placenta. It is widely accepted to be formed from hamartomatous proliferation of angioblastic cells in early placenta. According to groups who systematically examined the placentas with the greatest scrutiny, the incidence of chorioangioma is 1~1.2% of all placentas examined. The clinical implication of chorioangioma has been emphasized due to its high association with hydramnios, antepartum and postpartum hemorrhage, premature onset of labor, or intrauterine fetal distress or death. The authors experienced a case of a 38-year old multigravida who had undergone 4 consecutive spontaneous abortions. The fifth pregnancy was carried to 35 weeks whereupon a dead fetus was delivered. The placenta was enlarged(950 gm) with multiple protruding nodules into the fetal surface. Microscopically, the nodule was composed of many vilous structures lined by chorionic epithelium. Within these structures was proliferation of endothelial lined capillaries some of which demonstrated ectatic change.

Jung Keun KIM ; Heung Dong KIM
Journal of the Korean Child Neurology Society 1998;5(2):242-250
BACKGROUND: Juvenile myoclonic epilepsy(JME) is the most common idiopathic generalized epileptic syndrome which occurs mostly in the second decade of life. It is still frequently unrecognized and misdiagnosed. JME responds well to valproate, but is hardly controlled by other commonly used antiepileptic drug such as carbamazepine or phenytoin. We intended to Investigate the clinical symptoms and EEG findings of JME to support the diagnosis and treatment of JME. SUBJECTS AND METHODS: We retrospectively reviewed the medical record of 18 childrens with JME, from March 1991 to February 1997 We have analysed the clinical symptoms, seizure type, EEG findings including photosensitivity, and the effect of antiepileptic drug. RESULTS: 1) Seven patients were boys and eleven patients were girls(M : F=1 : 1.6). The seizure onset between 5 and 7 years of age were noted in 5 cases, that between 8 and 10 years in 5 cases, and in 8 cases seizures began after 11 years of age 2) Generalized convulsive seizures were noted in 16 cases(GTC 13, GC 2, GCTC 1), myoclonic seizures in 18 cases, absence seizures in 5 cases, and photoconvulsive seizures during video game were associated in 3 cases. 3) Epileptiform discharges at the diagnosis of JME were noted 12 cases(66.7%), and no epileptiform discharges were seen in 6 cases(33.3%). The background activities were normal in all cases. In all 12 cases that showed abnormal epileptiform discharge, generalized spike and wave discharges were obtained, and photosensitivies noted in 4 cases. 4) Follow up EEG obtained after treatment, showed normal EEG findings in 16 cases, and abnormal EEG findings were obtained in 2 cases. 5) Sixteen cases responded well to valproate monotherapy, and 2 other cases responded to valproate and ethosuximide combined therapy. In one case who received vigabatrin, the seizure was aggravated. 6) In 5 cases who discontinued antiepicoptic drug medication after 3 year seizure free duration, 3(60%) cases relapsed within 1 year, and 2(40%) cases remained seizure free for over 1 year. CONCLUSION: Juvenile myoclonic epilepsy is an epileptic syndrome with generalized convulsive seizure, myoclonic seizure, and absence seizure, and EEG findings showed generalized spike and wave discharge in 66.7%, and photosensitivity in 22.2%. JME responded well to valproate monotherapy or valproate and ethosuximide combined the rape, but not responded to other antiepileptic drugs.

The Journal of the Korean Orthopaedic Association 1990;25(5):1566-1571
Congenital high scapula, more commonly referred to as Sprengel's deformity, was first described by Eulenberg in 1863. Usually other congenital anomalies are associated such as absent or fused ribs, chest wall asymmetry, Klippel-Feil syndrome, cervical ribs, congenital scoliosis, cervical spina biffida was treated with the excision of the elongated acromion and the resection of prominent elongated acromion to be described is an extremely rare malformation. We experienced one case of congenital high scapula associated with anomaly of the acromion, which was treated with the excision of the elongated acromion and the resection of prominent supermedial border of the scapula for the purpose of the cosmetic and functional correction. After 1 year follow up, abduction was improved by only 10 degrees in the glenohumeral joint with the definite cosmetic improvement.

10.A Clinical Study of the Mechanism of Injury of Juvenile Tillaux Fracture and Triplane Fracture
Jun Dong CHANG ; Jung Chang LEE
The Journal of the Korean Orthopaedic Association 1990;25(5):1377-1384
The juvenile Tillaux fracture and the triplane fracture of the distal end of the tibia in adolescents are considered uncommon injuries and the mechanism of both injuries has been uncertain. It has been postulated that both fractures probably are caused by external rotation of the foot. We atempted to evaluate the mechanism of injury as well as to conform the role of the external rotation of the foot for the juvenile Tillaux fracture and triplane fracture. From 1983 to 1988 at the department of orthopedic surgery, college of medicine, Hallym University, we evaluated the cases of nine adolescent patients with the juvenile Tillaux fracture and nine patients with the triplane fracture of the distal tibial epiphysis. We confirmed that external rotation force produced the triplane fracture as well as juvenile Tillaux fracture. And we could postulate that the triplane fracture needed further external rotation force, less closure of the distal tibial epiphysis, and more complicated mechanism of injury than the juvenile Tillaux fracture. The knowledge of these mechanism of injury enables us to use a rational manipulative approach to reduce these fractures.
