Objective : In this study, we used the aged bilateral common carotid artery occlusion (BCAO) rats were used to measure the effect of Bupleuri Radix (Si-Ho) on the brain ischemic injury, because aging is an important factor in storke, Method : The brian ischemic injury was induced by temporary closing of carotids on both sides in a low blood pressure state. Bupleuri Radix (Si-Ho) was orally administered in 18-month-old BCAO rats. Result : The Ischemic Damaged Hippocampus and HSP expression were analyzed by the immunohistochemical staining and the result were as follows: 1. The low numbers of pyramid cells in the hippocampus CA1 area for the ischemically injured experimental group rose to numbers simillar to those of the control group. 2. The thin neuronal cell layer in the hippocampus CA1 area for the ischemically injured experimental group returned to thickness simillar to those of the control group. 3. The normalized optical density of HSP70 expression was suppressed in CA2, DG and CA1 expression was significantly suppressed in the experimental group compared to the control group. Conclusion : These results suggested that Bupleuri Radix (Si-Ho) has a neuroprotective effect by reducing neural cell injury in the initial ischemic state.

Although there are a few reports concerning the hepatic injury of herbal medicine in western medicine, there is no reports concerning the hepatic injury of herbal medicine in oriental medicine. We experienced one case of the hepatic injury suggested toxic hepatitis (drug induced hepatitis) in the treatment of oriental medicine for cerebral infarction. We make a reports for the progress of treatment. One patient of Rt hemiparesis diagnosed cerebral infarction in Brain MRI was administered Taeumin Yuldahanso-tang, treated with physical therapy and improved in the state of Rt hemiparesis(Gr 2/3,4). In the course of treatment, the patient intermittently complained of general weakness, dizziness, pericephalic discomfort(頭不淸), nausea, both leg weakness so we changed Taeumin Yuldahanso-tang to Soyangin Dokwhaljiwhang-tang. Alter that, the patient complained of general weakness, abdominal discomfort, heat and fever($38.4^{\circ}C$). We recognized the elevated total bilirubin(1.7mg/dl), serum transaminase(AST534U/L ALT720U/L), serum gammg glutamyl transpepridase (GGT106mg/dl) and Alk phosphatase124U/L. In the abdominal ultrasonogram there is hepatomegaly (16.5cm). We supposed hepatic injury suggested toxic hepatitis(induced hepatitis) of herbal medicine. After we administered Saeng gan gunbi-tang for 2days and Alk phosphatase and GGT inadequately was elevated. After that, we stopped administering medicine and the serum transaminase, total bilirubin, serum gamma glutamyl transpeptidase and Alk phosphatase level was decreased. In the abdominal ultrasonogram there was no signal. In the case, we supposed that the changing Sasang constitution and Sasang herbal medicine may induce hepatic injury. We are suggesting the necessity of a test for the hepatic injury of herbal medicine.

Following CNS injury, inhibitory influences at the site of axonal damage occur. Glial cells become reactive and form a glial scar, gliosis. Astrocyte-rich gliosis relates with up-regulation of GFAP and CD81, and eventually becomes physical and mechanical barrier to axonal regeneration. It is postulated that the astrocytic reaction is absent, regeneration of axons can occur. And it was reported that treatment with anti CD81 antibodies enhanced functional recovery in the rat with spinal cord injury. So in this current study, the author investigated the effect of the water extract of Persicae Semen on the regulation of GFAP and CD81 that increase when gliosis occurs. Persicae Semen decreased the expression of GFAP and CD81 in astrocyte cell by ELISA method. Persicae Semen decreased the RNA expression of CD81 and GFAP. The proteins that separate in whole cell were analaysed by western blot, and the expression of GFAP and CD81 was decreased. In vivo, rats brains were peformed cortical stab wound, the water extracts of Persicae Semen were injected for 7 days, 30 days. As a result, GFAP and CD81 expression were decreased in immunohistochemistry. These findings demonstrate that Persicae Semen decreases GFAP and CD81 expression. Accordingly, Persicae Semen could be a candidate for promotion of axon regeneration after CNS injury.

It is important to establish the safety of herbal medicine because of its frequent and widespread use in Korea. Several studies on the safety of herbal medicine have been performed and there have been rare serious adverse drug reactions from those reports in Korea. However, the results are not strongly supported because of not adopting appropriate enough research methodology as to make the safety issue clear. For improving the quality of the safety research on herbal medicine. including investigations of drug induced liver injury (DILl). the aim of this study was to suggest herbal medicine-induced liver injury investigation forms for performing reasonable safety research. After a systematic review of the preceding studies regarding herbal safety in Korea was performed in 2008, we assessed the quality and the limitations of the primary studies. Two investigation forms for herbal safety research were made as a following step. one a basic investigation form for herbal safety research and the other an advanced investigation form for suspected DILl cases, Those forms include the essential informations and data needed to make an appropriate assessment of whether DILl occurred during or after the use of herbal medicine. Guidelines for using those forms and other recommendations were also suggested. More rigorous studies are required for answering the safety issue of herbal medicine as well as the efficacy issue. We hope for wide use and improvement of those investigation forms in the study of herbal safety by many researchers for establishing better evidences in Korea.

연구배경 : 고열과 유독가스에 의한 흡입 폐 손상은 화상 환자에서 화재와 관련한 주된 사망원인이다. 따라서 조기진단과 적절한 치료가 중요한데, 본 연구는 초기 COHb 농도가 증가한 화상 환자의 임상 특성 및 경과를 관찰하고 흡입 폐 손상에 대한 예후인자를 알아보고자 하였다. 방 법 : 2001년 8월부터 2002년 7월까지 응급실 통해 내원한 1,416명 환자 중 동맥혈 가스검사에서 COHb 농도가 5% 이상인 39명을 사망군(12명)과 생존군(27명)으로 나누어, 임상특성, 임상적 흡입 손상 정도, 흉부 X-선 소견, 화상 체표 면적, APACHE II 점수, SAPS II 점수 등을 후향적으로 비교하였다. 결 과 : 생존군과 사망군 사이에 COHb 농도는 각각 $10.3{\pm}8.8%$, $9.7{\pm}5.7%$, 화상 체표면적은 $16.6{\pm}17.8%$, $60.7{\pm}28.8%$였다. 임상적 흡입 폐 손상 정도 및 초기 흉부 X-선 소견은 생존군과 사망군 사이에 유의한 차이점을 관찰할 수 없었다. 두 군사이의 사망관련 인자로는 화상 체표면적, APACHE II 점수, SAPS II 점수, 기계 호흡 및 총 입원기간이 관여하고 있었으나 다변량 분석에서 화상 체표 면적이 가장 중요한 사망관련 인자였다. 결 론 : 초기 동맥혈 COHb 농도가 증가되어 있는 화상환자의 예후는 불량할 것으로 기대되기 때문에 치료에 많은 관심을 기울여야 할 것으로 사료된다. 하지만, COHb이 흡입 폐 손상을 동반한 화상 환자의 예후에 미치는 효과에 대해서는 향후 전향적 연구를 통해서 검토되어져야 할 것으로 생각된다.

Objective: This study aimed to evaluate the inhibitory effects of SGX01 on the lung injuries of COPD mice model. Materials and Methods: This study was carried out in two ways: in vitro and in vivo. In vitro, L929 cells were challenged with LPS, and then treated with six concentrations of SGX01 (10, 30, 50, 100, 300, and $500{\mu}g/ml$) and analyzed by ELISA. In vivo, C57BL/6 mice were challenged with LPS and cigarette smoking solution (CSS), and then treated with a vehicle only (control group), dexamethasone 3 mg/kg (dexa group), or a SGX01 200 mg/kg (SGX01 group). After sacrifice, the BALF or lung tissue was analyzed with Cytospin, FACS, ELISA, real-time PCR and H&E, and Masson's trichrome staining. Results: SGX01 significantly decreased NO, $TNF-{\alpha}$, and IL-6 on L929 cells challenged with LPS. In the COPD model, SGX01 significantly inhibited the increase of neutrophils, $TNF-{\alpha}$, IL-17A, CXCL-1, MIP2, CD8+ cells in BALF, and $TNF-{\alpha}$, $IL-1{\beta}$ mRNA expression in lung tissue. It also decreased the severity of the histological lung injury. Conclusion: This study suggests the usability of SGX01 for COPD patients by controlling lung tissue injury.

In the context of the massive spread of coronavirus disease 2019 (COVID-19), the development of a COVID-19 vaccine is urgently needed. The Pfizer-BioNTech COVID-19 vaccine has been widely applied across global populations. Herein, we report a case of acute interstitial nephritis with acute kidney injury in a young healthy subject after administration of the COVID-19 vaccine. A 20-year-old man was admitted with abdominal discomfort and nausea. He had received the Pfizer-BioNTech COVID-19 vaccine 6 days before. At 9 days after vaccination, his kidney function was decreased, with serum creatinine levels of 1.8 mg/dL. Even with supportive care with hydration, his kidney function worsened, and he underwent a kidney biopsy. The pathology findings revealed diffuse interstitial infiltration of inflammatory cells, predominantly comprising lymphocytes, with preservation of the glomerulus. No abnormal findings were noted by immunofluorescence or electron microscopy. Based on a diagnosis of drug-related acute interstitial nephritis, we treated the patient with high-dose prednisolone. After administration of prednisolone, kidney function slowly improved. A close linkage between COVID-19 vaccination and acute interstitial nephritis should be considered in the clinic, despite the low incidence.

Objectives : This study aims to examine the multi-layered meanings of Li Dongyuan's concept of 'internal damage' through examining the origins of the 'internal damage' concept together with discussions derived from his 'Differentiation of Internal and External Damage'. Methods : Rather than Li's original works, those done by later doctors who were influenced by Li were thoroughly examined in this study to determine the relationships among internal and external damage, and external contraction. Results : Based on discussions related to the 'differentiation of internal and external damage' following Li, his concept of 'internal damage' could be understood as multi-layered, as it contains both spatial as well as pathogenic meaning. Therefore the meaning behind categorizations of internal and external damage, and internal damage and external contraction could be different. Li's 'internal damage' concept includes not only internal pathogen but elements of external contraction of wind and cold, which seems to have been integrated into the 'Cold Damage Theory' after Zhu Danxi, seemingly having changed the concept of cold damage. Therefore, discussions on the crossing between internal damage and external contraction have on one hand expanded the boundaries of each concept, while on the other hand, have caused confusion between the two at times. Conclusions : The concept of 'internal damage' has been widely accepted due to Li Dongyuan, on which related discussions have been centered. However, the concept was originally multi-layered, naturally leading to various discussions. Future studies should focus on the relationship of 'internal damage' with 'external damage' or 'external contraction', beyond the theories of Li.
