  • Purpose: In acute acetaminophen poisoning, the administration of N-acetylcysteine (NAC) can effectively treat the main complications, such as kidney injury and liver failure. In the current situation, measurements of the acetaminophen concentration are not checked in the usual medical facilities. Therefore, this study examined the factors of determining the administration of NAC in addition to the stated amount of intake. Methods: The medical records of patients who visited Ajou University Hospital emergency center with acetaminophen poisoning from January 2015 to December 2019 were reviewed retrospectively. One hundred and seventy-nine patients were initially included. Among these patients, 82 patients were finally selected according to the inclusion criteria in the study. The inclusion criteria were as follows: patients who were 15 years of age or older; those whose ingested dose, ingested time, and body weight were clearly identified; and patients whose acetaminophen sampling time was within 24 hours. Patients were divided into two groups: NAC administered vs. non-NAC administered. The following variables were compared in these two groups: ingested dose, ingested dose per body weight, hospital arrival time after ingestion, suicide attempt history, psychiatric disease history, classification of toxic/non-toxic groups, duration of hospitalization, and laboratory results. Results: Univariate analysis revealed the ingested dose per body weight, hospital arrival time after ingestion, suicide attempt history, and psychiatric disease history to be the determining factors in administering NAC. Logistic regression analysis confirmed that the ingested dose per body weight was the only significant factor leading to an NAC treatment decision. (Odds ratio=1.039, 95% Confidential interval=1.009-1.070, p=0.009) Conclusion: The ingested dose per body weight was the only determining factor for administering NAC in patients with acute acetaminophen poisoning. On the other hand, additional criteria or indicators for the NAC administration decision will be necessary considering the inaccuracy of the ingested dose per body weight and the efficiency of NAC administration.

  • Most inflammatory disorders are usually treated using anti-inflammatory drugs including non-steroidal anti-inflammatory drugs (NSAID) and steroidal anti-inflammatory drugs (SAID). Prolonged uses of NSAIDs and SAIDs may frequently cause adverse side-effects such as nausea, vomiting, diarrhea, constipation, decreased appetite, kidney and liver failure, ulcers, and prolonged bleeding after an injury or surgery. Thus, it is necessarily required to develop a new anti-inflammatory drug with little side-effects. Dandelion (Taraxacum officinale) possesses the therapeutic abilities to eliminate body heat and toxins and to remove swelling and inflammation. In order to verify the anti-inflammatory activity of dandelion, TPA(12-O-tetra decanoylphorbol-acetate)-induced or croton oil-induced acute edema was developed in the mouse ears, and dandelion extract dissolved in acetone was applied to both sides of inflamed ears. It was found that dandelion could significantly reduce the ear swelling, compared to that of non-treated control. In the case of $20{\mu}{\ell}$ application of $100mg/m{\ell}$ dandelion solution (DA-100), its anti-inflammatory effect was comparable to that of indomethacin, a non - steroidal anti-anflammatory drug. Taken together, it could be concluded that topically applied dandelion extract exhibited its potentials as a new drug candidate with an effective anti-inflammatory activity.

  • This study was done in order to investigate the etiology and pathology of dementia in the variety literature. Dementia in elderly persons(above the age of 60) mainly classfied Alzheimer disease and Cerebral vascular dementia. The results were as follows: 1. Dementia patients have abnormal mental function, who have no mental weakness but defects of memory, verbal disturbance, behavior disturbance and loss of intellectual function. 2. Dementia regard as 'me-beng(?病)', 'jeon-gwang(癲狂)', and 'heo-ro(虛勞)' in oriental medicine and the symptom is a silence with no response, mixing, a crying or a laugh, a stranger behavior and a amnesia; disturbances of speech, emotion, behavior. 3. Dementia caused by Alzheimer disease, Multi infarct dementia, Parkinson's disease, sequelae of acute CO poisoning, head injury and alcoholism(occidental medically) and the 'Dam(痰) and Damhwa(痰火), weakness of heart and spleen(心脾虛) caused by pent up anger of seven emotions(七情鬱結), the weakness of liver and kidney(肝腎不足)(oriental medically). 4. The causes of Alzheimer disease are various; a heredity factor, a morphological factor of brain tissues, a psychological factor and a biochemical factor (occidental medically) ; the 'Dam(痰) and Damhwa(痰火) caused by weakness of the internal organs and disturbance of the emotions(oriental medically). 5. Cerebral vascular dementia caused by loss of the certain cerebral neurons and oriental medically caused by obstruction of 'dam(痰)' or 'eo heul(瘀血)'. It is recommended that further study of many sided investigations, specially against a weakness of spiritual functions and a certain neurotoxin in the future.

  • This study aims to develop new potential therapeutic moracin M prodrugs acting on lung inflammatory disorders. Potential moracin M prodrugs (KW01-KW07) were chemically synthesized to obtain potent orally active derivatives, and their pharmacological activities against lung inflammation were, for the first time, examined in vivo using lipopolysaccharide (LPS)-induced acute lung injury model. In addition, the metabolism of KW02 was also investigated using microsomal stability test and pharmacokinetic study in rats. When orally administered, some of these compounds (30 mg/kg) showed higher inhibitory action against LPS-induced lung inflammation in mice compared to moracin M. Of them, 2-(3,5-bis((dimethylcarbamoyl)oxy)phenyl)benzofuran-6-yl acetate (KW02) showed potent and dose-dependent inhibitory effect on the same animal model of lung inflammation at 1, 3, and 10 mg/kg. This compound at 10 mg/kg also significantly reduced IL-1β concentration in the bronchoalveolar lavage fluid of the inflamed-lungs. KW02 was rapidly metabolized to 5-(6-hydroxybenzofuran-2-yl)-1,3-phenylene bis(dimethylcarbamate) (KW06) and moracin M when it was incubated with rat serum and liver microsome as expected. When KW02 was administered to rats via intravenous or oral route, KW06 was detected in the serum as a metabolite. Thus, it is concluded that KW02 has potent inhibitory action against LPS-induced lung inflammation. It could behave as a potential prodrug of moracin M to effectively treat lung inflammatory disorders.

  • Gadolinium chloride ($GdCl_{3}$) was known to block Kupffer cells and generally its toxicity study based on blocking these cells. Therefore, $GdCl_{3}$ frequently used to study toxic mechanisms of hepatotoxicants inducing injury through Kupffer cells. We also tried to investigate the effect of $GdCl_{3}\;on\;CCl_{4}$ toxicity, typical hepatotoxicants. Administration of $GdCl_{3}$ to mice significantly suppressed AST (asparatate amino transferase), ALT (alanine amino transferase) levels which were increased by $CCl_{4}$ treatment. However, $GdCl_{3}$ didn't inhibit the phagocytotic activity of Kupffer cells. Malondialdehyde (MDA) is a good indicator of the degree of lipid peroxidation. In this study, MDA increased by $GdCl_{3}$ administration not by $CCl_{4}$. To understand the toxicity of $GdCl_{3}$, we analyzed global gene expression profile of mice liver after acute $GdCl_{3}$ injection. Four hundred fifty two genes were differentially expressed with more than 2-fold in at least one time point among 3 hr, 6 hr, and 24 hr. Several genes involved in fibrogenesis regulation. Several types of pro-collagens (Col1a2, Col5a2, Col6a3, and Col13a1) and tissue inhibitor of metal-loproteinase1 (TIMP1) were up regulated during all the time points. Genes related to growth factors, chemokines, and oxidative stress, which were known to control fibrogenesis, were significantly changed. In addition, $GdCl_{3}$ induced abnormal regulation between lipid synthesis and degradation related genes. These data will provide the information about influence of $GdCl_{3}$ to hepatotoxicity.

  • Objectives: In recent years, there has been an increased need for a way to extract desired information from multiple medical literatures at once. This study was conducted to confirm the usefulness of unstructured data analysis using previously published medical literatures to search for new indications. Methods: The new indications were searched through text mining, network analysis, and topic modeling analysis using 5,057 articles of atorvastatin, a treatment for hyperlipidemia, from 1990 to 2017. Results: The extracted keywords was 273. In the frequency of text mining and network analysis, the existing indications of atorvastatin were extracted in top level. The novel indications by Term Frequency-Inverse Document Frequency (TF-IDF) were atrial fibrillation, heart failure, breast cancer, rheumatoid arthritis, combined hyperlipidemia, arrhythmias, multiple sclerosis, non-alcoholic fatty liver disease, contrast-induced acute kidney injury and prostate cancer. Conclusions: Unstructured data analysis for discovering new indications from massive medical literature is expected to be used in drug repositioning industries.

  • There is still controversy regarding clinical outcomes following primary hip arthroplasty after solid organ transplantation (SOT). The aim of this study was to determine whether clinical outcomes after hip arthroplasty differ between previous SOT recipients and control subjects with no history of undergoing SOT. We conducted a systematic search of MEDLINE, Embase, and the Cochrane Library for studies comparing the clinical outcomes after hip arthroplasty following SOT published up to January 5, 2022. A comparison of medical and surgery-related complications, as well as the readmission rate and 90-day mortality rate between previous SOT recipients and control subjects was performed. Subgroup analyses of the SOT types, liver transplantation (LT) and kidney transplantation (KT), were also performed. Ten studies that included 3,631,861 cases of primary hip arthroplasty were included; among these, 14,996 patients had previously undergone SOT and 3,616,865 patients had not. Significantly higher incidences of cardiac complications, pneumonia, and acute kidney injury were observed in the SOT group compared with the control group. Regarding surgical complications, a higher transfusion rate was observed in the SOT group. The readmission rate and 90-day mortality rate were also significantly higher in the SOT group. A significantly higher incidence of deep vein thrombosis was observed in the KT subgroup compared with the control group. A higher risk of medical and surgical complications, as well as higher readmission and mortality rates after hip arthroplasty was observed for previous SOT recipients compared to patients with no history of SOT.
