Amiodarone 폐독성은 약제 복용력이 있는 환자에서 새로운 증상과 X-선의 변화가 있을 때 의심하여야 하며 울혈성 심부전이나 폐감염증, 폐색전증, 악성종양 등과 감별하는 것이 중요하다. 진단은 임상적, 방사선학적, 조직학적 소견을 종합하여 내릴 수 있으며 대부분의 경우에는 약제 중단을 통해서 폐독성의 호전을 기대할 수 있으나 일부에서는 호흡부전으로 진행하거나 기존의 심부정맥의 재발 등으로 인하여 사망하는 경우도 있다. 저자들은 심부정맥으로 amiodarone을 사용하던 환자에서 치명적인 폐독성이 발생한 4예를 경험하였기에 이를 문헌고찰과 함께 보고하는 바이다. The lungs are frequently the site of adverse drug reactions because of their higher oxygen concentration, the distinctive properties of the pulmonary circulation, and the close proximity of the alveolar epithelium to the blood. Amiodarone, an iodinated benzofuran derivative, is an effective antiarrhythmic drug commonly used for refractory tachyarrhythmia. However, it has a wide range of adverse effects, the most serious of which is lung disease. Most patients present with the insidious onset of dyspnea and a nonproductive cough, and generally recover after withdrawing the drug. We recently experienced four fatal cases of amiodarone pulmonary toxicity. Therefore, we discuss these unusual drug-induced pulmonary toxicity cases with a review of the relevant literature.

Purpose: To establish a treatment regimen and preventive measures through clinical study and demographic profile of chemical corneal injury cases. Methods: The records of all patients presenting with chemical corneal injuries from January 1 1997 to December 31 2003 were evaluated. One hundred forty-three chemical corneal injuries in seventy-eight patients presenting to the Dongguk University Hospital were analyzed. Patients was divide into three groups in accordance to occupation (Group I, farmer, Group Ⅱ, directly chemical-agents exposure occupation, Group Ⅲ, others). The records were examined to extract information about age, sex, extent of injury, chemical substances involved, place of injury, delay time of arrival at hospital and visual acuity. Classification of corneal burns was scored according to Roper-Hall.1 Results: The patient consisted of 63 males (80.8%) and 15 females (19.2%), with a mean age of 39.21±13.27 years. The most common agent causing corneal injuries was pesticide, followed NaOH. Ninety-eight (68.5%) eyes showed Grade 1 burns, 27 (18.9%) eyes showed Grade 2, 15 (9.1%) eyes Grade 3 and 5 (3.5%) Grade 4. The severity of chemical corneal burn and deterioration of the visual acuity was more severe in group Ⅱ than in the other groups. Conclusions: Chemical ocular injuries may lead to serous visual impairment. Therefore, proper education for appropriate handling of chemicals to prevent the accidents is important.

Purpose : This study is to see the existence of the meridian and the meridian point through their response to the Young-Su-Bo-Sa. Objective and Methods : For this purpose, with acupuncture stimulation with Young-Su-Bo-Sa on the Hapkok of left hand and an the non-meridian point, and using the Digital infrared thermal image(D.I.T.I), We observed and analyzed the thermal changes of Hapkok, Samgan, non-meridian point(NA), Yonghyang, Soryo, Chonchu, Shingwol. Results and Conclusions : To sum up, We could understand Young-Su-Bo-Sa stimulation through the study findings that the acupuncture stimulation on the meridian point caused significant thermal changes of the associated meridian and meridian point, and Young-Su-Bo stimulation given in the direction of the meridian passage caused increases in the thermal changes of the associated meridian point, while Young-Su-Sa stimulation caused decreases in the thermal changes of the associated meridian point.

Sodium intake has been associated with the health-related quality of life (HRQoL). This study examined the demographic factors related to HRQoL and whether there is an association between sodium intake and HRQoL in adults residing in rural areas. A total of 1,980 adults (aged ≥20 years) were selected from a cross-sectional study conducted between December 2013 and February 2014 in Gyeongju, South Korea. The sodium intake and HRQoL were measured using a validated food frequency questionnaire and the EuroQol Five-Dimension (EQ-5D) (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), respectively. The education levels (<5 years) were inversely associated with all five dimensions of HRQoL. Men had better EQ-5D scores for each of the five components examined. Adults living with spouses had better scores related to usual activities and anxiety/depression, whereas widowers had decreased scores of mobility and self-care. Unlike older adults aged 70-79 years, adults aged <60 years were more likely to have greater scores related to mobility, usual activities, and pain/discomfort. The income levels were also inversely related to the scores for self-care, usual activities, pain/discomfort, and anxiety/depression. Sodium intake was positively associated with the HRQoL related to self-care, usual activities, and pain/discomfort, but it was negatively associated with anxiety/depression. In conclusion, these findings suggest that the demographic factors and sodium intake were independently associated with HRQoL. The results highlight the need to provide tailored, targeted policies and interventions that consider personal characteristics and dietary intake to improve the overall HRQoL in adults residing in rural areas.

산퇴적물에 대한 산림토양의 산성화 민감도를 평가하기 위하여 4개 지역 소나무림을 대상으로 토양내 추출성 황산이온 함량과 황산이온 흡착능을 정량하였다. 유기물층의 수용성 황산이온 함량은 강화와 홍천에 비해 울산과 남산에서 현저히 높아 황산화물의 지역적 유입특성을 반영하였다. 그러나 광물질 토양내 추출성 황산이온 함량은 황산화물의 유입량과 토양 흡착능의 상호작용으로 울산, 강화, 남산 및 홍천 순으로 높게 나타났다. 대기오염 우려지역인 남산, 강화 및 울산의 황산이온 특정흡착률(총 추출성에 때한 불용성의 비율)은 각각 16.6%, 56.8% 및 37.4%로써 산퇴적물에 대한 토양산성화의 상대적 민감도는 남산에서 가장 높았다. 황산이온 흡착등온식($RE=mX_i-b$)의 추가유입량($X_i$)과 흡착량(RE)간의 정의 상관성은 광물질 토양에서만 유의적으로(p<0.05) 나타났다. 흡착등온식의 회귀계수(m)로 나타낸 토심 30cm까지의 황산이온 흡착능은 남산, 강화, 울산 및 홍천에서 각각 0.16, 0.24, 0.25 및 $0.32mmol_c\;kg^{-1}$으로 이에 근거한 지역별 토양산성화 민감도는 남산에서 가장 높았다. 황산이온 영점흡착량(null-point adsorption)은 남산, 강화, 울산 및 홍천에서 각각 3.81, 2.17, 4.96 및 $0.65mmol_c\;kg^{-1}$으로 홍천을 제외한 나머지 지역은 현실적인 황산이온 퇴적량을 훨씬 초과하는 추정치이었다. The extractable sulfate content and sulfate adsorption capacity in soils of four Pinus densiflora stands were measured to assess the soil acidification sensitivity to acid deposition. The soluble sulfate content in organic horizon which reflects the previous deposition of sulfur oxides was much higher for Namsan and Ulsan than Kanghwa and Hongcheon. In mineral soils, however, the extractable sulfate content was the greatest for Ulsan followed by Kanghwa, Namsan and Hongcheon due to the interactive effect of previous deposition and soil adsorption of sulfate. Adsorption rates of specifically adsorbed sulfate(proportion of insoluble sulfate to total extractable sulfate) for Namsan, Kanghwa and Ulsan affected by acid deposition were 16.6%, 56.8% and 37.4%, respectively, so that the soil in Namsan had the highest acidification sensitivity to acid deposition. For sulfate adsorption isotherm($RE=mX_i-b$), the significantly positive correlations between added sulfate($X_i$) and adsorbed sulfate(RE) were found only in mineral soil(p<0.05) over all regions. The regression coefficient(m) that means soil sulfate adsorption capacity by 0-30cm depth was 0.16, 0.24, 0.25 and 0.32 in $mmol_c\;kg^{-1}$ for Namsan, Kanghwa, Ulsan and Hongcheon, respectively, indicating that soil acidification sensitivity is the highest for Namsan. The added sulfate($X_i$) that could make the adsorbed sulfate(RE) null was 3.81, 2.17, 4.96 and 0.65 in $mmol_c\;kg^{-1}$ for Namsan, Kanghwa, Ulsan and Hongcheon, respectively and the values of former three regions considerably exceeded the realistic sulfate deposition.
