  • Several lines of evidence indicate that the oxidative modification of protein and the subsequent accumulation of the modified proteins have been found in cells during aging, oxidative stress, and in various pathological states including premature diseases, muscular dystrophy, rheumatoid arthritis, and atherosclerosis. The important agents that give rise to the modification of a protein may be represented by reactive aldehydic intermediates, such as ketoaldehydes, 2-alkenals and 4-hydroxy-2-alkenals. These reactive aldehydes are considered important mediators of cell damage due to their ability to covalently modify biomolecules, which can disrupt important cellular functions and can cause mutations. Furthermore, the adduction of aldehydes to apolipoprotein B in low-density lipoproteins (LDL) has been strongly implicated in the mechanism by which LDL is converted to an atherogenic form that is taken up by macrophages, leading to the formation of foam cells. During the search for an endogenous inducer of cyclooxygenase-2 (COX-2), an inducible isoform responsible for high levels of prostaglandin production during inflammation and immune responses, 4-hydroxy-2-noennal (HNE), one of the most representative lipid peroxidation product, has been identified as the potential inducer of COX-2. In addition, the following study on the molecular mechanism of the COX-2 induction by HNE has unequivocally established that a serum component, which is eventually identified to be denatured LDL, is essential for COX-2 induction. Here I review current understanding of the mechanisms by which HNE in cooperation with the serum component activates gene expression of COX-2.

  • The purpose of this study is to analyze the level of obesity and sarcopenia among chronic obstructive pulmonary disease(COPD) patients in Korea. The current study recruited 75 patients with COPD who visited the department of respiratory medicine at J University Hospital in J-do. Height, body weight, waist circumference, and hip circumference were measured, and body composition, muscle strength, and flexibility were assessed. The levels of obesity were classified with body mass index(BMI), waist-hip circumference ratio(WHR) and percent body fat, and sarcopenia was classified with the value of skeletal muscle mass and muscle strength by Asian Working Group for Sarcopenia. In results, it was found that the level of obesity was very high as 43% by BMI, 88% by WHR, and 64% by percent body fat. The lower level of muscle strength was 15.50% in males and 23.50% in females. The lower level of muscle mass was 24.10% in males and .00% in females. Males who had one sarcopenia factors were 22.40%, and females were 23.50%, respectively. Males with sarcopenia were 6.90%, and females were .00%. In conclusion, regular resistance exercise is essential not only for the development of motor skills, but also for the normalization of skeletal muscle function and prevention of muscle dystrophy among COPD patients.

  • We report here a case of oral myiasis in the Republic of Korea. The patient was a 37-year-old man with a 30-year history of Becker's muscular dystrophy. He was intubated due to dyspnea 8 days prior to admission to an intensive care unit (ICU). A few hours after the ICU admission, 43 fly larvae were found during suction of the oral cavity. All maggots were identified as the third instars of Lucilia sericata (Diptera: Calliphoridae) by morphology. We discussed on the characteristics of myiasis acquired in Korea, including the infection risk and predisposing factors.

  • Two dogs presented with bilateral pattern-forming corneal opacity. Treatment with topical immunosuppressants was initiated after a complete ophthalmic examination. The response to treatment was assessed by analyzing serial images using slit-lamp biomicroscopy and spectral domain optical coherence tomography (SD-OCT). Both dogs responded to topical immunosuppressants; however, the lesions recurred once the treatment was abated or withdrawn. The most effective immunosuppressant in both dogs was 0.03% tacrolimus ointment. Early and continuous treatment with topical immunosuppressants may be necessary to improve corneal clarity and prevent scarring. SD-OCT could provide useful structural information regarding presumed immune-mediated keratitis and aid in monitoring treatment response.

  • "Sarcopenia", sarcopenia is an old age syndrome, and used to describe the reduction of skeletal muscle. Initially, it was thought that sarcopenia was only a senile disease characterized by degeneration of muscle tissue. However, its cause is widely regarded as multifactorial, with neurological decline, hormonal changes, inflammatory pathway activation, declines in activity, chronic illness, fatty infiltration, and poor nutrition, all shown to be contributing factors. Skeletal muscle mass can be measured by a variety of methods, currently, the commonly used methods are dual-energy X-ray scanning (DXA), computer tomography (CT), magnetic resonance imaging (MRI), etc. Muscular skeletal disorders can also be assessed by measuring appendicular skeletal muscle (ASM), particularly muscle tissue content. At the same time, sarcopenia refers to skeletal muscle cell denervation, mitochondrial dysfunction, inflammation, hormone synthesis and secretion changes and a series of consequences caused by the above process and is a progressive loss of skeletal muscle syndrome, which can lead to the decrease of muscle strength, physical and functional disorders, and increase the risk of death. Sarcopenia is mainly associated with the aging process, but also related to other causes such as severe malnutrition, neurodegenerative diseases, and disuse and endocrine diseases associated with muscular dystrophy, and it is the comprehensive results of multi-factors, so it is difficult to define that sarcopenia is caused by a specific disease. With the aging problem of the population, the incidence of this disease is increasingly common, and seriously affects the quality of the life of the elderly. This paper reviews the etiology and pathogenesis of myopathy, screening methods and diagnosis, the influence of eating habits, etc, and hopes to provide reference for the diagnosis and treatment of this disease. At present, adequate nutrition and targeted exercise remain the gold standard for the therapy of sarcopenia.

  • Objectives: Treating complex regional pain syndrome (CRPS) is difficult because it still does not have a recommended therapy. A 29-year-old man was diagnosed with CRPS after surgery on his $4^{th}$ and $5^{th}$ left toes 7 years ago. Though he had undergone diverse pain treatment, the symptoms persisted, so he visited Dunsan Korean Medicine Hospital of Daejeon University. This case report presents results on the effect of bee venom pharmacopuncture in treating patient with CRPS. Methods: Bee venom pharmacopuncture (BVP), 0.15 to 0.4 mL dosage, was administered at GB43. The treatment was applied each week for a total 14 times. The symptoms were evaluated using a numeric rating scale (NRS) and the dosage of pain medicine. Results: On the first visit, he was taking an anticonvulsant, a trycyclic antidepressant, and an analgesic. On the NRS the worst pain in the toes received a score of 8. He also complained of severe pain and hypersensitivity when the $4^{th}$ and the $5^{th}$ toes were touched just slightly. Other complaint included dyspepsia, rash, and depression. After treatment, on the NRS, the score for toe pain was 0, and he no longer needed to take pain medication. During the 4-months follow-up period, he has remained without pain; neither have additional symptoms appeared nor adverse events occurred. Conclusion: BVP may have potential benefits for treating patients with CRPS.

  • Neuropathic pain originating from multiple condition of nerve cell injury is common, but is difficult to treat. Even though many drugs such as anti-convulsants, anti-depressants, NSAIDs, opioids have been used, their clinical analgesic action were not satisfactory due to occur severe side effects. Gabapentin was introduced in 1994 as a novel antiepileptic drug and has been used to treat partial seizure. After 1995 gabapentin treatment for reflex sympathetic dystrophy (RSD) started, 45% of the reports about the analgesic efficacy of gabapentin were restricted to the treatments of non-epileptic pain syndrome. This drug is preferred to treat neuropathic pain because of a lower incidence of its side effects than those of other anti-convulsants and anti-depressants. For evaluating it's analgesic efficacy, the changes in the patients' subjective pain intensity was measured by the score on the visual analogue scale (VAS) and patient's objective pain intensity by measuring the skin temperature via infrared thermography were investigated respectively. Side effects of gabapentin were look into. We observed successful relief of neuropathic pain in the three patients which included post-herpetic neuraligia, complex regional pain syndrome (CRPS) and diabetic neuropathic pain, and the side effects of gabapentin were at acceptable levels.

  • Thr rickets or osteomalacia, that was induced by nonendocrine osseous or soft tissue tumor, is extremely rare disease and fourteen patients has been reported since 1947. The real nature of this disease is unknown, but postulated that unknown phosphaturic subtance which was elaborated from the tumor affect the renal tubule and produce hypophosphatemia and failure of calcification of osseous tissue. This case presented is that of 41-year-old man who suffered from severe generalized aching pain, severe muscular dystrophy, and shortening of the stature 4 years prior hospitalization. The causal coexisting tumor is walnut sized peripheral giant cell granuloma on the upper gingiva. After surgical removal of the tumor, patient's biochemical findings of the serum and urine were returned to the normal limits 12 days later, and clinical symptoms were marked relieved at 6 weeks later. The dental radiograms which were obtained 4 months later revealed remarkable bone regeneration and newly formed alveolar lamina dura.
