  • UV-irradiated skin shows acutely erythema, edema, pigmantation (sunbum) and chronically coarse wrinkling, roughness, dryness, laxity (photoaging). Jawoongo(紫雲膏, JW) is clinically useful external application and effective bum, sunburn, wound and symptom of dryness(燥症) in skin disease. In this experiment, we examined if JW could cure the UVB-mediated acute skin damages, inhibit UVB-mediated oxidative stress and inflammation of skin, and block the photoaging. In vivo test, we found that JW could effectively cure the UVB-mediated acute skin damages(erythema, edema, angiogenesis, hyperplasia, infiltration of lymphocytes) and inhibit expression of HSP70, CYP1A1 and p53. We also found that JW could repair destruction of collagen fiber and inhibit activation of MMP-9, and inhibit expression of $NF-{\kappa}B$ p65, iNOS, hyperplasia of keratynocyte. In vitro test, we found that JW could inhibit expression of IKK, iNOS mRNA, and production of NO. These findings shows that JW could cure the UVB-mediated acute skin damages, inhibit UVB-mediated oxidative stress and inflammation of skin, and block photoaging.

  • Anisomycin is known to inhibit eukaryotic protein synthesis and has been established as an antibiotic and anticancer drug. However, the molecular targets of anisomycin and its mechanism of action have not been explained in macrophages. Here, we demonstrated the anti-inflammatory effects of anisomycin both in vivo and in vitro. We found that anisomycin decreased the mortality rate of macrophages in cecal ligation and puncture (CLP)- and lipopolysaccharide (LPS)-induced acute sepsis. It also declined the gene expression of proinflammatory mediators such as inducible nitric oxide synthase, tumor necrosis factor-α, and interleukin-1β as well as the nitric oxide and proinflammatory cytokines production in macrophages subjected to LPS-induced acute sepsis. Furthermore, anisomycin attenuated nuclear factor (NF)-κB activation in LPS-induced macrophages, which correlated with the inhibition of phosphorylation of NF-κB-inducing kinase and IκB kinase, phosphorylation and IκBα proteolytic degradation, and NF-κB p65 subunit nuclear translocation. These results suggest that anisomycin prevented acute inflammation by inhibiting NF-κB-related inflammatory gene expression and could be a potential therapeutic candidate for sepsis.

  • Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as one of the most promising biomarkers of renal epithelial injury. Numerous studies have presented the diagnostic and prognostic utility of urinary and plasma NGAL in patients with acute kidney injury, chronic kidney disease, renal injury after kidney transplantation, and other renal diseases. NGAL is a member of the lipocalin family that is abundantly expressed in neutrophils and monocytes/macrophages and is a mediator of the innate immune response. The biological significance of NGAL to hamper bacterial growth by sequestering iron-binding siderophores has been studied in a knock-out mouse model. Besides neutrophils, NGAL is detectable in most tissues normally encountered by microorganisms, and its expression is upregulated in epithelial cells during inflammation. A growing number of studies have supported the clinical utility of NAGL for detecting invasive bacterial infections. Several investigators including our group have reported that measuring NGAL can be used to help predict and manage urinary tract infections and acute pyelonephritis. This article summarizes the biology and pathophysiology of NGAL and reviews studies on the implications of NGAL in various renal diseases from acute kidney injury to acute pyelonephritis.

  • Acute bronchitis and chronic obstructive pulmonary diseases (COPD) are essentially lung inflammatory disorders. Various plant extracts and their constituents showed therapeutic effects on several animal models of lung inflammation. These include coumarins, flavonoids, phenolics, iridoids, monoterpenes, diterpenes and triterpenoids. Some of them exerted inhibitory action mainly by inhibiting the mitogen-activated protein kinase pathway and nuclear transcription $factor-{\kappa}B$ activation. Especially, many flavonoid derivatives distinctly showed effectiveness on lung inflammation. In this review, the experimental data for plant extracts and their constituents showing therapeutic effectiveness on animal models of lung inflammation are summarized.

  • Apios americana Medik (hereinafter Apios) has been reported to treat diseases, including cancer, hypertension, obesity, and diabetes. The therapeutic effect of Apios is likely to be associated with its anti-inflammatory activity. This study was conducted to evaluate the protective effects of Apios in animal models of acute lung injury induced by lipopolysaccharide (LPS) or pandemic H1N1 2009 influenza A virus (H1N1). Mice were exposed to LPS or H1N1 for 2-4 days to induce acute lung injury. The treatment groups were administered Apios extracts via oral injection for 8 weeks before LPS treatment or H1N1 infection. To investigate the effects of Apios, we assessed the mice for in vivo effects of Apios on immune cell infiltration and the level of pro-inflammatory cytokines in the bronchoalveolar lavage (BAL) fluid, and histopathological changes in the lung. After induction of acute lung injury, the numbers of neutrophils and total cells were lower in the Apios-treated groups than in the non-Apios-treated LPS and H1N1 groups. The Apios groups tended to have lower levels of tumor necrosis factor-a and interleukin-6 in BAL fluid. In addition, the histopathological changes in the lungs were markedly reduced in the Apios-treated groups. These data suggest that Apios treatment reduces LPS- and H1N1-induced lung inflammation. These protective effects of Apios suggest that it may have therapeutic potential in acute lung injury.

  • Inflammation plays an important role in the progression of atherosclerosis and plaque destabilization converting a chronic process into an acute disorder with ensuing thromboembolism. Current therapeutic effective in preventing atherosclerosis and stroke such as statins, ASS and RAS inhibitors my exert part of their effects by modulating inflammatory responses in the vessel walls. As alternative approaches, discovery to find having inhibitory action of MMP activity, COX-2, macrophage infiltration, such as APE1/ref-1 and fusion technology for cell permeable protein may provide a new antiatherosclerotic therapy in the future.

  • 목 적 : 이식신 생검은 이식신 기능 이상의 원인, 거부반응의 정도, 예후 등을 확인하는데 도움이 된다. 그러나 이식신의 조직학적 변화가 신피질에 고르게 분포하지 않는 경우를 흔히 보게 된다. 따라서 본 연구는 이러한 이식신 생검에서의 잠재적인 표본추출의 오류를 평가하기 위하여 시행되었다. 방법 : 569개의 이식신 생검 표본 중에서 Banff criteria에 준하는 급성 거부반응을 보이고 있으며, 신피막부터 수질까지의 전 층을 포함하고 있는 신생검 표본 26개를 조사하였다. Banff criteria를 변형하여 조직의 변화를 간질성 염증(0-3+), 부종(0-3+), 요세관간질염(0-3+)으로 구분하여 급성거부반응의 등급을 표면 피질, 깊은 피질과 피질에 근접한 수질층 각각을 비교하여 조직학적 분석을 시행하였다. 결과 : 간질성 염증(P=0.019), 부종(P=0.023), 요세관 거부등급(P=0.019)에서 깊은 피질에서 표면 피질에 비해 급성 거부반응의 정도가 심하였다. 결론 : 이식신의 급성 거부반응을 진단하기 위하여 신생검을 실시 할 경우 깊은 피질이 포함되지 않으면 급성 거부반응을 과소 평가 할 수 있으므로 주의해야 할 것으로 사료된다.

  • Background: Acute transverse myelitis(ATM) is a group of disorders characterized by focal inflammation of the spinal cord and resultant neural injury. It can be diagnosed by Transverse Myelitis Consortium Working Group(TMCWG) criteria. But there are some cases which were not satisfied with idiopathic ATM criteria, both clinically and radiologically, especially in acute stage. So we analyzed 27 cases retrospectively, which were diagnosed as idiopathic ATM. Methods: All the records of the patients at Gil Medical Center with a diagnosis of idiopathic ATM from 2001 to 2005 were reviewed. And clinical manifestations including neurological examination, radiologic features and cerebrospinal fluid (CSF) findings were analyzed. Results: Among the patients(20 men and 7 women; mean age, 45.3 years), 11 cases could not be diagnosed as idiopathic ATM according to the TMCWG criteria ; 6 cases did not have well marginated upper sensory level and 5 cases were not satisfied with spinal cord inflammation. Conclusions: Although most cases of suspected idiopathic ATM were suitable for TMCWG criteria, some cases were not satisfied with this diagnostic criteria, especially in acute stage. Subsequent study might be needed to evaluate the reliability and clinical application of the criteria.

  • Purpose: In general, Acute Pyelonephritis is effectively treated with the use of antibiotics. However, some antibiotics are reported to cause side effects, and the abuse of antibiotics results in the increase of the disease's tolerance to antibiotics. Recently, I have effectively treated five cases of Acute Pyelonephritis by using only Constitution - Acupuncture and Herb, and therefore I would like to report about these cases. Methods: I diagnosed Acute Pyelonephritis of these five patients by confirming symptoms and employing a urine analysis with reagent strip(Multi $stix{\circledR}$). I used Kuon's method of constitutional diagnosis for the purpose of the diagnosis of the constitutional 8 morbidities. I relied on Sungjeong(性情) and Chehyungkisang(體刑氣像) in diagnosing Sasang Constitutions(四象人). I performed acupuncture on the left and right sides, depending on 8 constitutions, by employing Chang - temperament Inflammation Formula(臟系炎症方) that is used for the treatment of all kinds of chang-temperament inflammation diseases, as well as Bactericidal Formula(殺菌方) that is used for the treatment of all kinds of bacterially caused diseases. I prescribed by consulting the appearance of disease and general symptoms of each case with Dongyi Soose Bowon(東醫壽世保元)'s prescription symptoms. Result: Two of them showing severe symptoms were hospitalized, while three others took OPD treatment. The patient who was PANCREOTONIA and Soyangin improved through hospitalization for three days, another patient who was PULMOTONIA and Taeyangin with severe symptoms, improved through hospitalization for seven days, and completely recovered through OPD treatment later. The three others took only OPD treatment, and improved within 5-7 days. Conclusion: I confirmed that each of 8-constituions and Sasang Constitutions were all treated effectively without antibiotics.

  • The alteration in the pharmacokinetic behaviors of organic cations (OCs) in rats during acute inflammation (AI) was investigated. AI was induced by an intraperitoneal injection of lipopolysaccharide (LPS, 5 mg/kg) 24 hr prior to the start of pharmacokinetic studies. Tributylmethylammonium (TBuMA) was selected as a model OC since it is largely excreted into bile, and is neither metabolized nor binds to proteins in the body. When TBuMA was administered intravenously to AI rats at a dose of 6.6 $\mu$mole/kg, the AUC was increased, while biliary excretion (i.e., cumulative amount and apparent clearance) was decreased compared to normal rats. When TBuMA was administered intravenously to AI rats at a constant rate (i.e., a bolus injection at a dose of 1.5 $\mu$mole/kg followed by a constant infusion at a rate of 1.5 $\mu$mole/kg/hr for 165 min), steady-state concentrations of plasma and liver concentrations of TBuMA were increased significantly, while in vivo hepatic uptake (amount) and canalicular excretion (clearance) were decreased. These results are consistent with a hypothesis in which both the sinusoidal uptake of TBuMA into hepatocytes via the OCT1 and the canalicular excretion of the compound from hepatocytes via the P-gp are decreased by LPS-induced AI.
