Whole-body exposure to high-dose radiation causes injury involving multiple organs that depends on their sensitivity to radiation. This acute radiation syndrome (ARS) is caused by a brief exposure of a major part of the body to radiation at a relatively high dose rate. ARS is characterized by an initial prodromal stage, a latent symptom-free period, a critical or manifestation phase that usually takes one of four forms (three forms): hematologic, gastrointestinal, or cardiovascular and neurological (neurovascular), depending upon the exposure dose, and a recovery phase or death. One of the most important factors in treating victims exposed to radiation is the estimation of the exposure dose. When high-dose exposure is considered, initial dose estimation must be performed in order to make strategy decisions for treatment as soon as possible. Dose estimation can be based on onset and severity of prodromal symptoms, decline in absolute lymphocyte count post exposure, and chromosomal analysis of peripheral blood lymphocytes. Moreover, dose assessment on the basis of calculation from reconstruction of the radiation event may be required. Experience of a criticality accident occurring in 1999 at Tokai-mura, Japan, showed that ARS led to multiple organ failure (MOF). This article will review ARS and discuss the possible mechanisms of MOF developing from ARS.

Osteoarthritis(degenerative joint disease), the most common arthropathy affecting the aged people, is characterized by degeneration of articular cartilage with proliferation and remodeling of subchondral bone. Osteoarthritis of the knee, which probably has greater social cost and more associated disability than osteoarthritis of any other joint, prevalence is known to increase with age, and females have higher rates than males; radiographic abnormalities are present in more than 30% of persons more than 65 years old, with approximately 40% of these persons symptomatic. Though the etiology of osteoarthritis is not entirely understood, much information is available regarding risk factors for the development of knee osteoarthritis that permit some reasonable guideline for preventive strategies. Traumatic damage or occupational or recreational overuse of knee joint may result in osteoarthritis, and obesity also is related to osteoarthritis of the knee. A variety of other possible risk factors for the development of knee osteoarthritis have been proposed, including increased bone mass, smoking, diseases such as diabetes or elevated serum uric acid, and some metabolic factors, but the contribustions of these and other factors such as smoking or race and diseases such as diabetes are as yet undetermined. The usual clinical manifestations include pain, stiffnesss, crepitus and loss of function. In oriental medicine, osteoarthritis of the knee is very similar to diseases such as Bijung(痺症), Haksulpung(鶴膝風), Youkjeolpung(歷節風) in symptoms. The diseases such as Bijung(痺症), Haksuipung(鶴膝風), Youkjeolpung(歷節風) is related to the of function liver(肝) and kidney(腎) and risk factors are regarded as Pung(風), Han(寒), sub(濕). The diagnosis of osteoarthritis of the knee has often been based on radiographic appearance and clinical manifestations. The acupuncture therapy of osteoarthritis of the knee has often been based on Stomach meridian(ST), Spleen meridian(SP), Kidney meridian(KI), Liver meridian(LR).

Purpose: The purpose of this study was to provide basic data to improve coping abilities of elementary school students in emergency situations. Method: The data were collected from 1633 3-6th grade elementary school students using a self-report questionnaire. Results: 1) The mean score for the coping ability of the students was low at .38(${\pm}.36$). 2) The mean scores for the 8 categories were, [Care for common symptoms], .54(${\pm}.48$), [Call for help & check], .47(${\pm}.43$), [Care for injury by heat cold & foreign body], .39(${\pm}.45$), [Care for tissue damage], .36(${\pm}.44$), [Offering help], .36(${\pm}.42$), [Rescue & escape], .31(${\pm}.51$), [Evacuation], .28(${\pm}.49$), and [Appropriate response for the situation], .27(${\pm}.43$). The mean scores for 2 areas were, 'Acting tips', .35(${\pm}.36$) and 'First aid', .42(${\pm}.40$). There were significant differences in coping ability according to students' gender (t=4.964, p<.001), and family type (t=-2.484, p=.013). 4) Among the categories, there were significant correlations between all 8 categories and significant correlation between 'Acting tips' and 'First aid' (r=.808, p<.001), 'Acting tips' and 'Coping ability' (r=.956, p<.001), and 'First aid' and 'Coping ability' (r=.946, p<.001). Conclusion: The findings indicate a need for programs to improve the coping ability of elementary school students in emergency situations.

Menkes disease is an X-linked recessive copper transport disorder characterized by neurological deterioration, connective-tissue damage, and abnormal hair growth. It is caused by the mutation of the ATP7A gene. This report describes a four-month-old boy with neurological symptoms typical of Menkes disease plus unusual liver involvement. He developed seizures at three months of age and exhibited hypotonia, cephalhematoma, a sagging face, redundant and hypopigmented skin, and abnormal hair growth. In addition, he had unexplained hepatomegaly and high hepatic transaminase. We confirmed the diagnosis of Menkes disease by mutation analysis of the ATP7A gene. To exclude other possible causes for the hepatic abnormalities, a liver biopsy was performed, revealing intracytoplasmic cholestasis, focal spotty necrosis, and minimal lobular activity. The patient's liver involvement may be an underestimated complication of Menkes disease.

Traumatic brain injury, which can be caused by head trauma, can damage the brain, resulting in physical disorders, such as headache, dizziness, and nausea, as well as mental health problems, such as depression, anxiety, memory loss, and personality changes that reduce a person's quality of life. Therefore, it is important to administer the best treatment at the right time. A 57-year-old patient complained of headache and depression after intracranical hemorrhage caused by a traffic accident. These symptoms are considered to be after effects of brain trauma due to increased pressure on the brain. Herbal medicine was prescribed to release internal brain pressure and acupuncture was applied to ease frontal and occipital head muscle tension. Objective scales were conducted at baseline, and at one month, two months, and four months. It was observed that the degree of headache and depression improved after treatment. This study is meaningful in that it found that Korean medicine treatments help alleviate the after effects of traumatic brain injury.

Morus alba root extract (MARE) has been used to treat hyperglycaemic conditions in oriental medicine. Here, we studied whether MARE possesses a cytotoxic effect on neuroblastoma. To check the cytotoxicity generated by MARE was whether relatively higher against the cancer cells rather than normal cells, we chose a neuroblastoma cell line (B103) and a normal cell line (Rat-2). A CCK assay revealed that MARE ($10{\mu}g/ml$) reduced cell viability to approximately 60% compared to an untreated control in B103 cells. But in Rat-2 cells, MARE induced relatively lower cytotoxicity. To investigate the mechanisms underlying the cytotoxic effect of MARE, we used flow cytometry combined with immunoblot analyses. We found that MARE-treatment could accumulate ROS and depolarize mitochondria membrane potential of B103 cells. Further treatment with MARE in B103 cells also could damage DNA and induce apoptosis. An expression study of p-Akt also suggested that there was a reduction in cellular proliferation and transcription along with the process of apoptosis, which was further evidenced by an increase in Bax and cleaved-caspase 3 activity. Together, our findings suggest that MARE produces more cytotoxicity in cancer cells while having a relatively attenuated effect on normal cells. As such, MARE may be a safer option in cancer therapeutics, and it also shows potential for the patients with symptoms of hyperglycemia and cancer.

Objectives : This study is performed to investigate the therapy on tinnitus through the literature of Eastern and Western medicine. Methods : This study review the definition, etiology, classification, internal and external methods of treatment of tinnitus based on 50 articles of Eastern medicine, 16 articles of Western medicine about the treatment of tinnitus. Results : The results were as follows. 1. In Eastern medicine, the cause and mechanism of disease of tinnitus arose from the state of qi-blood deficiency, internal dampness-heat and depression stagnation. In Western medicine, there are mainly caused by damage to the auditory system the lower induced changes in the upper. 2. In Eastern medicine, differentiation of syndromes classifies clinical aspects, and cause and mechanism of disease. In Western medicine, it divides into an generating region, clinical and associated symptoms aspects. 3. In Eastern medicine, internal method of treatments of tinnitus are divided into four treatments. In Western medicine, internal methods of tinnitus are vasodilators, blood-flow improvers, Metabolism improvers etc. 4. In Eastern medicine, external method of treatments of tinnitus are paste preparation method, powder preparation method, pill preparation method, acupuncture & moxibustion method. In Western medicine, external method of treatments of Tinnitus are divided into injection, other surgical therapies and adjuvant therapy. Conclusions : Until now, there is no perfect, effective single treatment. We think that Eastern medicine approach and treatment can be helpful to overcome the limitations of tinnitus cure.

Purpose: An aneurysm is defined as a permanent, localized dilation of an artery with a 50% increase in diameter over its expected normal diameter. Aneurysms can be classified by cause as traumatic and nontraumatic. Traumatic aneurysms can be divided into true and false aneurysms. Nontraumatic causes of peripheral artery aneurysms include mycotic, atherosclerotic, inflammatory, and idiopathic. In the hand, true aneurysms occurring at the common digital artery have been rarely reported. We present a rare case of a true aneurysm of the common digital artery that was resected and reconstructed using a reversed vein graft. Methods: A 49-year-old male patient was refered to our institution with a $0.73{\times}0.44{\times}1.37cm$ sized pulsating mass between 2nd and 3rd flexor digitorum tendons on Lt. palm area. The mass had been present for 5 years and had increased in size over the previous year. No history of trauma was reported. After a physical examination and ultrasound sonography review, a diagnosis of aneurismal dilatation of common digital artery was made. Surgical treatment by excision of the aneurysm, and a reversed vein graft was performed. Results: Histologic examination of the specimen ($3.4{\times}0.7cm$) showed aneurismal dilatation, with elastin fibers present in the arterial wall. The lesions were healed without any complications and there were no evidence of recurrence. Doppler examination of the reconstruction showed good perfusion. Conclusion: Early excision is recommended to relieve symptoms and avoid neurologic damage. Also, artery reconstruction can be performed by primary end-to-end anastomosis or the placement of a reversed interposition vein graft. Micro surgical repair was the only possible treatment in this case. The authors believe that the vascular anatomy should always be restored as natural as possible.

Objectives : Alcohol use disorder (AUD) is often comorbid with adult attention-deficit hyperactivity disorder (ADHD) and other psychiatric illnesses. When associated with other mental problems, the prognosis of the AUD can be more serious. This study shows research on the clinical and neuropsychological characteristics according to whether or not ADHD symptoms and AUD were comorbid. Methods : A total of 64 adult inpatients who completed AUD scales about adult ADHD, alcohol dependence, depression, anxiety, and impulsiveness. They also completed neuropsychological tests about attention and executive function. According to the Adult ADHD Self-Report Scale score, patients were categorized into two groups (ADHD symptom positive/negative group). Results : Fourteen among the 64 subjects were part of the ADHD symptom positive group (21.9%). They had statistically significant shorter abstinence periods and a higher rate of history of 'rule violation during school' and 'physical damage in childhood' compared to the ADHD symptom negative group. Conclusion : The comorbidity rate with ADHD symptom in adult AUD is higher than the general population. The ADHD symptom positive group suffered from more severe and refractory AUD. Considering the more frequent history of rule violation during school in the ADHD symptom positive group, the association between ADHD and AUD may be mediated by conduct disorder. Therefore we suggest the necessity of careful evaluation and intervention in children and adolescents with ADHD and conduct disorder.
