Objectives : The concepts of many Korean medicine terms have changed for a long time and cumulatively been recorded in later medicine literatures. And, the same terms have very often been used for different meanings depending on context. Methods : This study was performed so that conceptual magnitude of Korean medicine terms could intuitively be recognized for the purpose of quantization. Results : This study was performed under the premise that terms used in old literatures of Korean medicine are related mostly to treatments that could immediately be reverted to types of medical herbs used. Through this, conceptual magnitude of terms was quantified by the method that frequency of medical herbs used for treatment was changed to numerical values. For this, data of "Compilation of Formulas and Medicinals Addendum" were used. First, after 'specificity' of each medicine herb corresponding to representative disease symptoms was calculated, medians in the set were selected, and 'values of conceptual magnitude' for representative disease symptoms were calculated. Conclusions : As a result, if disease symptoms are diverse, concept range is diachronically changed greatly, and specific disease symptoms of great conceptual difference are included, value of conceptual magnitude was great. Meanwhile, if disease factor and treatment are singular or limited to several types, and many medical herbs with high specificity are used, value of conceptual magnitude was less.

Intestinal giant-cystic disease (IGCD) of the Israel carp (Cyprinus carpio nudus) has been recognized as one of the most serious diseases afflicting inland farmed fish in the Republic of Korea, and Thelohanellus kitauei has been identified as the causative agent of the disease. Until now, studies concerning IGCD caused by T. kitauei in the Israel carp have been limited to morphological and histopathological examinations. However, these types of diagnostic examinations are relatively time-consuming, and the infection frequently cannot be detected in its early stages. In this study, we cloned the full-length 18S rRNA gene of T. kitauei isolated from diseased Israel carps, and carried out molecular identification by comparing the sequence with those of other myxosporeans. Moreover, conventional PCR and real-time quantitative PCR (qPCR) using oligonucleotide primers for the amplification of 18S rRNA gene fragment were established for further use as methods for rapid diagnosis of IGCD. Our results demonstrated that both the conventional PCR and real-time quantitative PCR systems applied herein are effective for rapid detection of T. kitauei spores in fish tissues and environmental water.

Plant diseases are a significant yield and quality constraint for farmers around the world due to their severe impact on agricultural productivity. Such losses can have a substantial impact on the economy which causes a reduction in farmer's income and higher prices for consumers. Further, it may also result in a severe shortage of food ensuing violent hunger and starvation, especially, in less-developed countries where access to disease prevention methods is limited. This research presents an investigation of Directional Local Quinary Patterns (DLQP) as a feature descriptor for plants leaf disease detection and Support Vector Machine (SVM) as a classifier. The DLQP as a feature descriptor is specifically the first time being used for disease detection in horticulture. DLQP provides directional edge information attending the reference pixel with its neighboring pixel value by involving computation of their grey-level difference based on quinary value (-2, -1, 0, 1, 2) in 0°, 45°, 90°, and 135° directions of selected window of plant leaf image. To assess the robustness of DLQP as a texture descriptor we used a research-oriented Plant Village dataset of Tomato plant (3,900 leaf images) comprising of 6 diseased classes, Potato plant (1,526 leaf images) and Apple plant (2,600 leaf images) comprising of 3 diseased classes. The accuracies of 95.6%, 96.2% and 97.8% for the above-mentioned crops, respectively, were achieved which are higher in comparison with classification on the same dataset using other standard feature descriptors like Local Binary Pattern (LBP) and Local Ternary Patterns (LTP). Further, the effectiveness of the proposed method is proven by comparing it with existing algorithms for plant disease phenotyping.

Objective: Parkinson's disease (PD) is the second most common neurodegenerative disease after Alzheimer's disease. Antioxidant stress and inflammatory reactions are important causes of neurodegenerative diseases and are major causes of PD. Many animal experiments have been aimed at treating PD using the antioxidant effects of various traditional medicines and dietary supplements. This review reports the research investigating the antioxidant effects of herbs in in vivo PD models. Methods: The study consisted of a database search for articles related to PD and herbal treatments using the OASIS, NDSL, KTKP, Korean KISS, PubMed, Science Direct, CNKI, Wanfang, and J-STAGE databases. The search period was limited from the start of the search engine application to November 14, 2019. Studies were selected to confirm the antioxidant effects of herbal medicines in an in vivo PD model. Results: Eighty-two studies were summarized for plant species, extracts (or compounds), animal models, neurotoxins, and functional results. The most frequently used herbal materials were Bacopa monnieri, Camellia sinensis, Centella asiatica, and Withania somnifera. MPTP and 6-OHDA were the most commonly used neurotoxins for inducing PD. Most studies confirmed an increased expression and activation of antioxidant enzymes and a decrease in oxidative stress. Herbal materials showed their antioxidant effects regardless of the order of treatment and confirmed their possible use as treatments for the prevention and treatment of neurodegeneration. Conclusion: Many herbal medicines have antioxidant effects and are likely to be effective in delaying neurodegenerative damage by inhibiting or reducing oxidative stress by expression of antioxidant enzymes.

The increasing prevalence of toxic substance-exposure in pets in South Korea endangers the health and safety of numerous companion animals, and has become a cause for concern. Notably, the annual incidence of forensic analysis in pets has increased by more than 150% in South Korea, mainly in populous regions such as Seoul, Incheon, and Gyeonggi. In response to this growing issue, veterinary forensic examinations were conducted on 549 dogs and cats from 2019 to 2022. This study revealed the presence of various toxic substances, including pesticides, insecticides, and drugs such as analgesics, anesthetics, antidepressants, and muscle relaxants, in pets. Among the 38 different toxins identified in pets, coumatetralyl, methomyl, terbufos, and buprofezin were the most frequently detected. In this study, toxic substances for pets were identified based on the "toxic agent list for humans," developed by the National Forensic Services, because no list of toxic agents for animals currently exists and data regarding potentially toxic substances for dogs and cats is limited. This is one of the limitations of this study, and necessitates the establishment of a toxic agent list for animals. Continued monitoring and research is also recommended to reveal the incidence, causes, and solutions of toxicity in animals.

연구배경 : Neuron specific enolase (NSE)는 뇌조직의 신경원에서 처음 발견된 당분해 효소이며, APUD 세포 및 신경내분비계에도 존재하는 것으로 알려졌다. 소폐포폐암은 신경내분비세포 및 APUD 세포와 많은 공통점을 가지고 있다. 따라서 NSE 항체를 사용하는 면역조직화학 염색과 혈청내 NSE 농도측정은 신경내분비 분화를 하는 폐종양의 표지자로서 사용될 수 있으며 소세포폐암의 진단에 유용할 수 있다. 방법 : 소세포폐암으로 진단받은 22명과 대조군으로는 비소세포폐암환자 21명을 대상으로 하였으며 생검조직에서 NSE 항체를 이용한 면역조직화학염색을 시행하고 환자의 혈청에서 방사면역측정법으로 NSE 농도를 측정하였다. 결과: 1) NSE 항체를 이용한 면역조직화학염색 NSE 항체를 이용한 면역조직화학영색에서 소세포폐암군 환자는 18명중 9명에서 양성 반응을 보였으며, 비소세포폐암 환자중 면역조직화학염색을 시행한 16명중 5명에서 양성 반응을 보였다. 2) 방사면역 측정법에 의한 혈청 NSE농도 측정 비소세포폐암군의 혈청 NSE평균치는 $11.79{\pm}4.47\;ng/ml$이었으며 소세포폐암군의 혈청 NSE치는 개인차가 심하기는 하였으나(6.01~361.4 ng/ml) 그 평균치는 $59.30{\pm}77.88\;ng/ml$으로 두 군 사이에는 유의한 차이가 있었다. 소세포폐암환자중 limited disease군의 혈청 NSE 평균치는 $20.19{\pm}12.91\;ng/ml$이었으며, extended disease군의 혈청 NSE치는 역시 개인차가 심하기는 하였으나(17.15~361.44 ng/ml) 그 평균치는 $91.9{\pm}94.2\;ng/ml$로 두 군 사이에 유의한 차이를 보였다. 정상인에서의 혈청 NES 농도는 측정하지 않았으나 대조군인 비소세포폐암군환자 평균+2x표준편차인 20 ng/ml을 기준으로 할 때 소세포폐암환자 22명중 16명(73%)에서 증가된 소견을 보였고 이중 limited disease는 50%(5/10), extended disease는 92% (11/12)에서 증가되었으며, 비소세포암 환자중에서는 1명(1/21)만이 증가된 소견을 보였다. NSE 혈청농도와 면역조직화학염색 정도를 비교시 소세포폐암군과 비소세포폐암군 모두에서 유의한 상관관계를 보이지 않았다. 결론 : 혈청 NSE농도측정은 소세포폐암환자에서 암표지자로서 유용한 방법이 될 수 있을 것으로 사료되며 항 NSE 항체를 이용한 생검조직의 면역조직화학염색은 분화가 나빠 고식적인 현미경적 소견만으로는 소세포암과 비소세포암과의 강벌이 어려운 경우 정확한 조직유형 결정과 신경내분비 기원을 뵈이는 폐암의 진단에 도움을 줄 수 있을 것으로 사료된다.

Gaucher disease is a lysosomal storage disease caused by deficiency of glucocerebrosidase (GBA). This condition is characterized by accumulation of glucocerebrosidase in liver, spleen, lung, skeletal system, and central nervous system. Gaucher disease is the prototype of disease in which efficacy of enzyme replacement therapy has been established. However, because recombinant enzyme is not able to enter the central nervous system, its efficacy is limited to the non-neurological manifestations of Gaucher disease. Importantly, approximately a half of Korean patients with Gaucher disease suffer from neurological manifestations. In addition, Korean Gaucher disease patients exhibit distinct mutation spectrum from those in other populations. Common mutations in Korean patients with Gaucher disease are also associated with neurological phenotype. Therefore, therapeutic strategies tailored to Korean patients were necessary. Interestingly, a chemical chaperone, ambroxol, has been known to increase residual enzymatic activities of the select mutant GBAs encoded by mutations prevalent in Korean patients. One promising aspect of this drug is that it can cross blood-brain barrier, and enhance the enzyme activity in the brain. In vitro study suggested this chemical chaperone as one of new therapeutic agents in Gaucher disease, and a well-designed human trial is required to confirm its efficacy.
