Overall purposes of neuropsychological tests are summarized as follows: 1) Indentifying brain damage in individuals who have symptoms of uncertain etiology; 2) Assessing the extent and nature of deficits for forensic purposes and planning appropriate intervention; 3) Evaluating the effects of intervention or rehabilitation; 4) Examining the effects of various types of brain damage across different populations; and 5) Testing theoretical propositions about brain-behavior relationship. Of the neuropsychological tests, the Luria-Nebraska Neuropsychological Battery(LNNB) is easily transportable, relatively inexpensive, and performable by trained technician. The Korean version of LNNB is now being designed and will be used clinically in the near future. Localization and equipotential theories of brain function had been prevalent until Luria's theory of brain function. Brain, composed of three brain units in the theory, is the functional system in which each brain area has specific function and produce the function-related behavior. LNNB consists of 11 clinical scales, 5 summary scales, 8 localization scales, and 28 factor scales.
Objectives: The aim is to identify any anti-tumor effects of Duchesnea indica(Andr.) Focke on colon cancer cells. Materials & Methods: Colo201 human adenocarcinoma cells were obtained from American Type Culture Collection. The boiled extract of Duchesnea indica(Andr.) Focke was added (10 and 20 microliters) to cultures and observed at 0, 6, and 12 hours, and at 12-hour intervals thereafter. Morphological changes in colon cancer cells were observed through an inverted microscope, Destruction of colon cancer cells was measured through Trypan blue exclusion testing. Suppression of the viability of colon cancer cells were measured via MTT assay. Anti-cancer mechanisms in the cell cycle of colon cancer cells were analysed via flow cytometry. Results: After introduction of Duchesnea indica(Andr.) Focke to cultures several changes were seen. Significant atrophy of the nucleus and cytoplasm of colon cancer cells was observed, indicating cell injury. Destruction of colon cancer cells was observed in direct proportion to dosage and duration. Suppression of viability of colon cancer cells for each test group was greater than that of the control group increasingly over time(36h, 48h, 60h, 72h), which was statistical significant (p<0.05). Cell numbers of the mitosis phase of the colon cancer cell cycle reduced. Conclusions: Statistcally significant anti-tumor effects of Duchesnea indica(Andr.) Focke were observed in this in vitro experiment. Results support a role for Duchesnea indica(Andr.) Focke in treatment of colon cancer. though it will required progressive research to develop a practical treatment.

Introduction: An unexpected death was reported in a beginner immediately after starting the work at a plating factory. After the incident, air sampling was performed using a simulation of the situation as it had been at the time. Methods: To evaluate the airborne concentration of hydrogen cyanide, a total of six samples were collected: one personal sample, three area samples, and two background samples (office and outdoors). Hydrogen cyanide measurement was performed according to the standard sampling protocol recommended by the U.S. NIOSH (National Institute of Occupational Safety and Health). Results: The highest concentration of hydrogen cyanide was 0.938 ppm measured in a sample collected from the plating bath area with local exhaust ventilation. This value was approximately 20% of the ceiling occupational exposure limit. The personal sample showed a concentration of 0.135 ppm. Samples collected near the bath in which the incident occurred and a dehydrator showed hydrogen cyanide concentrations of 0.236 ppm and 0.101 ppm, respectively. Hydrogen cyanide was not detected in the background samples (office and outdoors). Conclusions: It is necessary to use proper ventilation systems and respirators in plating factories to prevent acute poisoning. Furthermore, it is important to educate and train new workers dealing with toxic substances.
Introduction The Sasang Urination Defecation Inventory was developed to analyze Sasang-type specific pathophysiological clinical symptoms, and its revised Sasang Urination Inventory (SUI) illustrated its clinical usefulness in Sasang type differentiation. However, the correlation with established clinical measures for its concurrent validity were not provided yet. Methods Total of 48 healthy university students were recruited to response Urogenital Distress Inventory-6 (UDI-6) and Overactive Bladder Symptom Score (OABSS) of Western medicine along with the SUI of traditional Korean medicine. The correlation coefficients between UDI-6 and OABSS and SUI were acquired with Pearson's correlation, and Analysis of Variance (ANOVA) and Profile Analysis were used to analyze significant differences in SUI subscale profiles of each Sasang types. Results The SUI-HSS of urogenital hypersensitivity correlated positively with OABSS (r=0.442, p<0.01), and the SUI-DIS of urinary discomfort positively with UDI-6 (r=0.289, p<0.05). Interestingly, the SUI-total was correlated positively with age (r=0.326), height (r=0.318) and weight (r=0.304). The SUI-DIS for urinary discomfort of So-Yang (9.48±2.11) type was significantly (p<0.05) higher than that of Tae-Eum (7.2±2.90) type. And SUI subscale profiles of each Sasang type were significantly (Wilks' Lambda=0.792, F=2.723, p=0.034) distinctive to each other. Discussion The acceptable convergent validity of SUI was shown using established measures of urogenital symptoms. The SUI might be used as an objective traditional Korean clinical measure for Sasang type differentiation and urological patients.

This study is a report on recently discovered medical records based on traditional medicine in the 1900s. First, the contents of the records and their significance are described in detail. Next, a simple example of the research follows, in order to explain the medical and historical significance the records contain and to answer the question of how this historical document can contribute to future medical and historical studies. The documents dealt with in this study, the Chunggang Medical Records, are medical records compiled by a Korean doctor of oriental medicine by the name of Younghun Kim who practiced in the center of Seoul for a period of over 60 years. The records, which eventually amounted to over 1,500 books, were made known to the academic world when the descendents recently donated them to Kyunghee University. The reason these medical records attract so much attention from academic circles, even though they are the work of one individual, is that they contain abundant information on general public medical health at the time, in addition to the fact that Kim Younghun was a well known figure among Oriental Medicine doctors in Korea. The medical records start in 1915 and continue until Kim Younhun's death in 1974, though they have some damaged or missing parts. Kim's medical records are a gold mine not only for scholars studying the medical history of the early 1900s, but also for doctors trying to emulate the techniques embedded in a great predecessor's medical practice.
Background: Cancer reseach is done in earnest world-wide, because cancer is one of most threatening diseases to humans. Orostachyos Herba is a widely used herb that has long been in use in Korea as an anti-inflammatory and anti-cancer therapy. The purpose of this study is to verify any anti-cancer effects on stomach and liver cancer in vitro. Materials & Methods: AGS and KATO III stomach cancer cells and Hep3B and HepG2 liver cancer cells, all obtained from Korean Cell Line Bank, were used. The boiled extract of Orostachyos Herba(20 and 40 microliters) were injected into cultures and observed at 0 hours, and at 24-hour intervals up to 96 hours. The destruction of stomach and liver cancer cells was measured through Trypan blue exclusion testing. The suppression on viability of stomach and liver cancer cells was observed, and anti-cancer mechanisms was examined by analyzing the cell cycle. Results: In morphologic change, AGS, KATO III, HepG2 and Hep3B showed some of the withdrawn and floating appearance that is typical in cellular imparment. AGS, KATO III, HepG2 and Hep3B showed more destruction of stomach cancer cells in each test group than in the control group to a statistically significant degree. Analysis of the cell cycle after introduction of Orostachyos Herba showed very little inhibition of divisions of all cell lines. Conclusions: This experiment suggests that Orostachyos Herba has some anti-tumor effects on stomach and liver cancer cells. Progressive research on Orostachyos Herba and it's anti-tumor effects will be needed to determine its practicability as a cancer treatment.
Objectives : This paper serves to explore current trends of systems biology in Traditional Chinese Medicine (TCM) and examine how it may influence the Traditional Korean medicine. Methods : Literature review method was collectively used to classify Introduction to systems biology, diagnosis and syndrome classification of systems biology in TCM perspective, physiotherapy including acupuncture, herbs and formula functions, TCM systems biology, and directions of academic development. Results : The term 'Systems biology' is coined as a combination of systems science and biology. It is a field of study that tries to understand living organism by establishing a theory based on an ideal model that analyzes and predicts the desired output with understanding of interrelationships and dynamics between variables. Systems biology has an integrated and multi-dimensional nature that observes the interaction among the elements constructing the network. The current state of systems biology in TCM is categorized into 4 parts: diagnosis and syndrome, physical therapy, herbs and formulas and academic development of TCM systems biology and its technology. Diagnosis and syndrome field is focusing on developing TCM into personalized medicine by clarifying Kidney yin deficiency patterns and metabolic differences among five patterns of diabetes and analyzing plasma metabolism and biomarkers of coronary heart disease patients. In the field of physical therapy such as acupuncture and moxibustion, researchers discovered the effect of stimulating acupoint ST40 on gene expression and the effects of acupuncture on treating functional dyspepsia and acute ischemic stroke. Herbs and formulas were analyzed with TCM network pharmacology. The therapeutic mechanisms of Si Wu Tang and its series formulas are explained by identifying potential active substances, targets and mechanism of action, including metabolic pathways of amino acid and fatty acid. For the academic development of TCM systems biology and its technology, it is necessary to integrate massive database, integrate pharmacokinetics and pharmacodynamics, as well as systems biology. It is also essential to establish a platform to maximize herbal treatment through accumulation of research data and diseases-specific, or drug-specific network combined with clinical experiences, and identify functions and roles of molecules in herbs and conduct animal-based studies within TCM frame. So far, few literature reviews exist for systems biology in traditional Korean medicine and they merely re-examine known efficacies of simple substances, herbs and formulas. For the future, it is necessary to identify specific mechanisms of working agents and targets to maximize the effects of traditional medicine modalities. Conclusions : Systems biology is widely accepted and studied in TCM and already advanced into a field known as 'TCM systems biology', which calls for the study of incorporating TCM and systems biology. It is time for traditional Korean medicine to acknowledge the importance of systems biology and present scientific basis of traditional medicine and establish the principles of diagnosis, prevention and treatment of diseases. By doing so, traditional Korean medicine would be innovated and further developed into a personalized medicine.
Introduction: A post-traumatic mesenteric arteriovenous fistula (AVF) is extremely rare. Case Report: A previously healthy 26-year-old male was injured with an abdominal stab wound. Computed tomography (CT) showed liver injury, pancreas injury and a retropancreatic hematoma. We performed the hemostasis of the bleeding due to the liver injury, a distal pancreatectomy with splenectomy and evacuation of the retropancreatic hematoma. On the 5th postoperative day, an abdominal bruit and thrill was detected. CT and angiography showed an AVF between the superior mesenteric artery (SMA) and the inferior mesenteric vein with early enhancement of the portal vein (PV). The point of the AVF was about 4 cm from the SMA's orifice. After an emergent laparotomy and inframesocolic approach, the isolation of the SMA was performed by dissection and ligation of adjacent mesenteric tissues which was about 6 cm length from the nearby SMA orifice, preserving the major side branches of the SMA, because the exact point of the AVF could not be identified despite the shunt flow in the PV being audible during an intraoperative hand-held Doppler-shift measurement. After that, the shunt flow could not be detected by using an intraoperative hand-held Doppler-shift measuring device. CT two and a half months later showed no AVF. There were no major complications during a 19-month follow-up period. Conclusion: Early management of a post-traumatic mesenteric AVF is essential to avoid complications such as hemorrhage, congestive heart failure and portal hypertension.

Salurnis marginella Guérin-Méneville, 1829 (Hemiptera: Flatidae) is an invasive species first reported in 2003 in Iksan, which is located in the mid-western region of South Korea, and subsequently found in the nearby regions in 2005. However, molecular-perspective reports on their invasive characteristics are not yet available. In this study, population genetic characteristics of Korean S. marginella were evaluated using the mitochondrial COI region and sequencing 124 individual samples collected in 11 Korean localities. A total of 12 haplotypes were identified with a maximum sequence divergence of 1.368% (9 bp). Haplotype diversity was relatively higher than that of other insect species invaded into Korea, providing 2-6 haplotypes per populations, indicating that introduction to Korea may have happened rather extensively and consistently. Nucleotide diversity (π) was the highest in Iksan but owing to the limited sample size (three individuals) from this locality, additional studies are required for drawing conclusive inference regarding the place of entry to Korea. Ulsan, the easternmost population in the present study, revealed nearly the lowest diversity estimates, such as the lowest H and the second-lowest π; a unique haplogroup with a higher frequency; and an independent genetic cluster, suggesting that the introduction of S. marginella to Ulsan was an independent event. Further collection in Korea and neighboring countries, including the original distributional range is necessary to elucidate the invasive dynamics of S. marginella

Introduction: Chronic subdural hemorrhage (CSDH) primarily affects the elderly, and its incidence is rising due to aging trends. Although burr-hole craniostomy is a common treatment for CSDH, it often has a high recurrence rate and can sometimes result in poor outcomes. Oryeong-san, a traditional Korean medicine, is emerging as a potential remedy, with documented cases in both Korea and Japan. Case Presentation: In March 2021, a patient was diagnosed with an intracerebral hemorrhage in the left basal ganglia. A subsequent brain computed tomography in June 2022 revealed CSDH. Given the potential need for surgery if no CSDH absorption occurred, the patient was treated with Oryeong-san. Later computed tomography scans indicated that surgery was no longer necessary. Conclusions: This study evaluated the efficacy of Oryeong-san in treating CSDH. The results demonstrated complete CSDH absorption with no observed side effects, highlighting Oryeong-san as a promising and safe therapeutic option.
