Objectives : This study investigated whether taking herbal medicine over the long-term had any side effects of liver damage. Methods : We checked LFT levels of the 58 admitted patients. Results : When we compared admission LFT levels with discharge LFT levels, we found the levels of AST, ALT and LDH had decreased. This test showed statistically significant decrease. When we compared admission LFT levels with discharge LFT levels, we found the increases of discharge LFT levels fell within the standard deviation. When we compared admission LFT levels with discharge LFT levels, we found the levels of LFT did not increase as much as two standard deviations. Conclusions : According to the above results, taking herbal medicine over a long-term did not have any side effects of drug-induced liver damage.

Background: Oxidation plays an important role in acute lung injury. This study was conducted in order to elucidate the effect of repetitive post-treatment of N-acetylcysteine (NAC) in lipopolysaccaride (LPS)-induced acute lung injury (ALI) of rats. Methods: Six-week-old male Sprague-Dawley rats were divided into 4 groups. LPS (Escherichia coli 5 mg/kg) was administered intravenously via the tail vein. NAC (20 mg/kg) was injected intraperitoneally 3, 6, and 12 hours after LPS injection. Broncho-alveolar lavage fluid (BALF) and lung tissues were obtained to evaluate the ALI at 24 hours after LPS injection. The concentration of tumor necrosis factor ${\alpha}$ (TNF-${\alpha}$) and interleukin $1{\beta}$ (IL-$1{\beta}$) were measured in BALF. Nuclear factor ${\kappa}B$ (NF-${\kappa}B$), lipid peroxidation (LPO), and myeloperoxidase (MPO) were measured using lung tissues. Micro-computed tomography (micro-CT) images were examined in each group at 72 hours apart from the main experiments in order to observe the delayed effects of NAC. Results: TNF-${\alpha}$ and IL-$1{\beta}$ concentration in BALF were not different between LPS and NAC treatment groups. The concentration of LPO in NAC treatment group was significantly lower than that of LPS group ($5.5{\pm}2.8$ nmol/mL vs. $16.5{\pm}1.6$ nmol/mL) (p=0.001). The activity of MPO in NAC treatment group was significantly lower than that of LPS group ($6.4{\pm}1.8$ unit/g vs. $11.2{\pm}6.3$ unit/g, tissue) (p<0.048). The concentration of NF-${\kappa}B$ in NAC treatment group was significantly lower than that of LPS group ($0.3{\pm}0.1\;ng/{\mu}L$ vs. $0.4{\pm}0.2\;ng/{\mu}L$) (p=0.0001). Micro-CT showed less extent of lung injury in NAC treatment than LPS group. Conclusion: After induction of ALI with lipopolysaccharide, the therapeutic administration of NAC partially attenuated the extent of ALI through the inhibition of NF-${\kappa}B$ activation.

연구배경 : 다형핵구는 폐조직세포들을 방어하는데도 중요한 역할을 하지만, 방어기전을 수행하는 과정에서 오히려 폐조직세포들의 손상을 초래하기도 한다. 그러나 다형핵구에 의한 폐조직세포 손상이, 폐조직세포들에 대한 다형핵구의 직접적인 세포득성작용에 의한 것인지, 혹은 다형핵구로부터 유리되는 어떤 세포독성 매개물질에 의한 것인치에 대해서는 아직 불확실하다. 한편 histamine은 알레르기성 질환 및 일부 호흡기질환의 병인에 중요한 매개물질로 작용하기도 하지만, 다형핵구의 여러 기능들을 조절하는 작용도 하는 것으로 알려져 있다. 따라서 저자를온 다형핵구에 의한 폐조직세포의 손상기전을 보다 명확히 이해하고, 이에 대한 히스타민의 영향을 연구하기 위해 본 연구를 시작하였다. 방법 : $^{51}Cr$을 부착시킨 A549 폐포세포와 4명의 건강한 비흡연자들의 말초 정맥혈로부터 분리한 다형핵구 혹은 다형핵구 상충액을 함께 배양하여 발생되는 폐포세포 손상정도를 $^{51}Cr$-release assay로 측정하여 비교하는 한편, 각각의 경우에 다형핵구를 histamine으로 전처치함으로써 나타나는 변화를 관찰하였다. 결과 : 1) 세포자극제의 종류와 농도 및 전처치한 히스타민의 농도에 따라 다소 차이는 있었지만, 전반적으로 다형핵구 자체에 의한 폐포세포 손상 정도보다는, 다형핵구상충액에 의한 폐포세포 손상 정도가 더 심한 경향을 보였다. 2) Histamine으로 전처치한 다형핵구 자체에 의한 폐포세포 손상 정도는, HBSS만으로 전처치한 다형핵 자체에 의한 폐포세포 손상 정도에 비해, 전처치한 histamine의 농도와 다형핵구 자극제의 종류 및 농도에 따라 억제 혹은 증강되는 일정치 않은 양상을 나타냈다. 3) Histamine으로 전처치한 다형핵구의 상층액에 의한 폐포세포 손상 정도는, HBSS만으로 전처치한 다형핵구의 상층액에 의한 폐포세포 손상 정도에 비해, 전반적으로 억제되는 경향이 있었다. 결론 : 이상의 연구결과 다형핵구에 의한 폐세포 손상은, 다형핵구의 폐포세포에 대한 직접적인 세포독성 작용보다는 활성화된 다형핵구로부터 분비되는 어떤 세포독성 물질들에 의해 매개되는 것으로 생각되며, histamine은 정상적으로는 다형핵구의 세포독성작용을 억제하나, 다형핵구와 폐포세포간의 상호작용시에는 주위의 미세환경에 따라 다르게 작용할 수도 있을 것으로 추측된다.

The internal breakdown of Fuji apple during CA storage classified as watercore breakdown, low temperature breakdown and CO2 injury. This study was undertaken to investigate the watercore breakdown injury factors of Korean Fuji apple during CA storage. The development of internal breakdown was more increased with the larger size, the later harvest time and the hither CO2 gas level. But in internal breakdown fruit of the titratable acidity and soluble solid decreased significantly, the pH of fruit juice and the production of carbon dioxide was greatly increased. The best gas levels of CA storage was 2% oxygen and 3% carbon dioxide. Thus, the predictable parameters of internal breakdown of fruit were increase in pH on decrease titratable acidity within 2 months of CA storage, increase carbon dioxide. So, it was found that the best CA sotrage for internal breakdown control of fruit during CA storage was delayed CA storage methods after low temperature storage immediate harvest of apple and than took a step. The delayed CA storage after low temperature storage for 2 months was more effective in the prevention of development of internal breakdown than immediate CA storage after harvest.

This study aimed to evaluate the protective effects of Mundongcheongpye-eum (MCE) on elastase-induced lung injury. The extract of MCE was treated to A549 cells and elastase-induced lung injury mice model. Then, various parameters such as cell-based cyto-protective activity and histopathological finding were analyzed. MCE showed a protective effect on elastase-induced cytotoxicity in A549 cells. This effect was correlated with analysis for caspase 3 levels, collagen and elastin contents, protein level of cyclin B1, Cdc2, and Erk1/2, and gene expression of TNF-${\alpha}$ and IL-$1{\beta}$ in A549 cells. MCE treatment also revealed the protective effect on elastase-induced lung injury in mice model. This effect was evidenced via histopathological finding including immunofluence stains against elastin, collagen, caspase 3, and protein level of cyclin B1, Cdc2, and Erk1/2 in lung tissue. These data suggest that MCE has a pharmaceutical properties on lung injury. This study would provide an scientific evidence for the efficacy of MCE for clinical application to patients with chronic obstructive pulmonary disease.

Three dogs (7-year-old, neutered male Chihuahua; case 1, 1-year-old, spayed female mixed breed; case 2, 10-month-old, female Maltese; case 3) were referred to Jeju Veterinary Medicine Teaching Hospital for traumatic brain injury. All three patients exhibited abnormal neurological symptoms. The patients were diagnosed through medical history obtained from their caregivers and through computed tomography (CT) or magnetic resonance imaging (MRI) scans. Structural brain abnormalities were observed in two dogs through CT scans and in one dog through MRI. Decompression therapy with mannitol was administered to all three dogs. Case 1, which showed CT findings of pulmonary hemorrhage but no significant brain injury, and case 2, which had mild brain damage on CT imaging, showed improvement in neurological symptoms and gait abnormalities after decompression therapy. However, case 3, which showed suspected brain hemorrhage and brain edema on MRI, did not respond to decompression therapy and was euthanized one month later. Imaging evaluation through CT or MRI in dogs with traumatic brain injury can assist clinical veterinarians in assessing the prognosis of patients.

Background: The aim of this study was to examine the influence of body mass index (BMI) on the development of acute kidney injury (AKI) in critically ill patients in intensive care unit (ICU). Methods: Data of patients admitted to medical ICU from December 2011 to May 2014 were retrospectively analyzed. Patients were classified into three groups according to their BMI: underweight (< $18.5kg/m^2$), normal ($18.5-24.9kg/m^2$), and overweight (${\geq}25kg/m^2$). The incidence of AKI was compared among these groups and factors associated with the development of AKI were analyzed. AKI was defined according to the Risk, Injury, Failure, Loss of kidney function, and End-stage (RIFLE) kidney disease criteria. Results: A total of 468 patients were analyzed. Their mean BMI was $21.5{\pm}3.9kg/m^2$, including 102 (21.8%) underweight, 286 (61.1%) normal-weight, and 80 (17.1%) overweight patients. Overall, AKI occurred in 82 (17.5%) patients. The overweight group had significantly (p<0.001) higher incidence of AKI (36.3%) than the underweight (9.8%) or normal group (15.0%). In addition, BMI was significantly higher in patients with AKI than that in those without AKI ($23.4{\pm}4.2$ vs. $21.1{\pm}3.7$, p<0.001). Multivariate analysis showed that BMI was significantly associated with the development of AKI (odds ratio, 1.893; 95% confidence interval, 1.224-2.927). Conclusion: BMI may be associated with the development of AKI in critically ill patients.

Atherosclerotic renal artery stenosis (RAS) may result in hypertension, azotemia, and acute pulmonary edema. We report on a renal angioplasty with stent placement for bilateral RAS in a patient with acute decompensated heart failure and acute kidney injury. A 67-year-old female patient was admitted to our hospital with acute shortness of breath and generalized edema. Echocardiography showed left ventricular wall motion abnormality and the follow up electrocardiography showed T wave inversion in the precordial leads. We performed a coronary angiography to differentiate ischemic heart disease from non-cardiac origin for the cause of the heart failure. The coronary angiography showed no significant luminal narrowing, but bilateral RAS was confirmed on the renal artery angiography, therefore, we performed renal artery revascularization. After the procedure, the pulmonary edema was improved and the serum creatinine was decreased. Two weeks later, an echocardiography showed improvement of the left ventricular systolic function.
