In Korea, Korean Medicine is the first choice in treating stroke. Because stroke prognosis, risk of recurrence, and choices for management are influenced by stroke subtype, correct analysis of stroke subtype is important. Until now, the studies on differentiation of the symptoms and signs for the stroke were a few and the Korean standard differentiation of the symptoms and signs for the stroke don't exist. To develop the Korean standard differentiation of the symptoms and signs for the stroke, we go through subtype of stroke in traditional chinese medicine, Korean Medicine, western medicine.

Improving liver regeneration (LR) remains a medical issue, and there is currently a lack of safe and effective drugs for LR. Rhizoma Dioscoreae (SanYak, SY) is a traditional Chinese medicine. However, the underlying action mechanism of SY treatment for LR is yet to be fully elucidated. To explore the mechanism by which SY affects LR, we have conducted a series of methods for network pharmacological analysis, molecular docking, and in vivo experimental validation in mice. Overall, 9 compounds and 30 predicted target genes of SY were found to be associated with the therapeutic effects of LR. Compared with the model group, hematoxylin and eosin staining revealed that the mice with preoperative drug intervention possessed fewer postoperative hepatocyte bubbles and relatively regular morphology. Furthermore, the serum alanine transaminase and aspartate aminotransferase levels were reduced, immunohistochemistry revealed elevated proliferating cell nuclear antigen positivity rate, and Western blotting demonstrated that the phospho-protein kinase B (AKT)/AKT ratio was downregulated and that vascular endothelial growth factor A (VEGFA) expression levels were upregulated. This study explored dioscin, the main active ingredient of SY, and its potential therapeutic effects on LR. It repairs damaged liver following surgery and promotes liver cell proliferation. The action mechanism comprises reducing AKT phosphorylation levels and upregulating VEGFA expression levels. Thus, this study provides a new direction for further research on the mechanism of SY promoting LR.

In Korean Medicine (KM), the Yin-Yang doctrine is still used as a theoretical tool for understanding and explaining the clinical experiences. However, as the traditional culture declined in East Asia and the scientific culture took over, there was an increased negative view on the Yin-Yang doctrine, and thus a heightened distrust over KM. For KM to survive in an unfamiliar culture of science, a novel outlook on the Yin-Yang doctrine is needed. In this sense, I consider a thoroughly medical take on the Yin-Yang doctrine to be most important. The focus needs to be on the goals of medicine: this includes riddance of any discourses on Yin-Yang that cannot contribute to the goals, and an enhancement of the Yin-Yang concept as a rational and scientific terminology. One way to achieve this is by understanding Yin-Yang as a type of metaphor. The Yin-Yang doctrine that is utilized in KM corresponds well to the conceptual metaphor suggested by Lakoff and Johnson. As a metaphor, the Yin-Yang concept plays a role in structuring the target domain, that is life phenomena, metaphorically. Through the Yin-Yang metaphors, the life phenomena are understood as the Yin-Yang phenomena, and are systematically organized by the subcategories contained in the Yin-Yang doctrine. Understanding Yin-Yang as a metaphor is a good way to enhance the Yin-Yang concept and doctrine as a rational terminology and method.

In traditional medicines, Dansam-samul-tang and Samwhang-sasim-tang extracts were known to effects of antioxidant and antimicrobial activity. To investigate the safety evaluation of skin, these extracts were measured to skin safety testing such as primary skin irritation test, eye irritation test and skin sensitization test. The results of the primary skin irritation test and eye irritation test in vitro showed that these extracts included in the nonirritating area. Skin sensitization test results by Guinea Pig Maximization (GPMA) indicated that there was no allergy reaction. Therefore, Dansam-samul-tang and Samwhang-sasim-tang extracts were very safe in every safety test of skin. These results suggests that Dansam-samul-tang and Samwhang- sasim-tang extracts in 1 % concentration can be useful cosmetic ingredients.

Hypothyroidism alone can lead to myocardial fibrosis and result in heart failure, but traditional hormone replacement therapy does not improve the fibrotic situation. Hydrogen sulfide (H₂S), a new gas signaling molecule, possesses anti-inflammatory, antioxidant, and anti-fibrotic capabilities. Whether H₂S could improve hypothyroidism-induced myocardial fibrosis are not yet studied. In our study, H₂S could decrease collagen deposition in the myocardial tissue of rats caused by hypothyroidism. Furthermore, in hypothyroidism-induced rats, we found that H₂S could enhance cystathionine-gamma-lyase (CSE), not cystathionine β-synthase (CBS), protein expressions. Finally, we noticed that H₂S could elevate autophagy levels and inhibit the transforming growth factor-β1 (TGF-β1) signal transduction pathway. In conclusion, our experiments not only suggest that H₂S could alleviate hypothyroidism-induced myocardial fibrosis by activating autophagy and suppressing TGF-β1/SMAD family member 2 (Smad 2) signal transduction pathway, but also show that it can be used as a complementary treatment to conventional hormone therapy.

Bile juice prevents deposition of cholesterol in the blood vessel, digests fat, and absorbs fatty acid and vitamins, and it plays a great role on metabolism. Recently, emotional stimulus and mentally over-depression cause a person to come to illness, and westernization of way of life makes more patients with cholelithiasis, resulting into without bile secretion after cholelithotomy. Ageing, and gastrectomy and kidney transplantation are also the causes of more cholelithiasis occurrences. To solve these medical problems, we studied how Fel Sus Scrofa, which is not different from human bile juice, was used in the traditional Korean medicine. We I researched flavor, property, efficacy of Fel Sus Scrofa and how it was used by folk medicine, and we studied the usage examples of Fel Sus Scrofa in Sanghanlon and Dongeuibogam. The property of Sus Scrofa is bitter and cold. Its efficacy is to deposit glycogen. So it is known that it has been widely used, with many edible forms, without any humoral loss, for the inflammatory disease from various fever, problems of urine and feces, cutaneous disease, pulmonary disease, opthalmopathy, fever, thirst from diabetes, hepatocystic duct disorder. Fel Sus Scrofa can be used internally and externally to prevent humoral loss, and to control cutaneous disease among various pediatric disorder full of fever. And as we have in mind that it also can be used to treat patients with cholestasis after cholecystectomy, it is expected that post study of it must be done.

Korean red ginseng (KRG) has been used worldwide as a traditional medicine for the treatment of various reproductive diseases. Gonadotropin releasing hormone (GnRH) neurons are the fundamental regulators of pulsatile release of gonadotropin required for fertility. In this study, an extract of KRG (KRGE) was applied to GnRH neurons to identify the receptors activated by KRGE. The brain slice patch clamp technique in whole cell and perforated patch was used to clarify the effect of KRGE on the membrane currents and membrane potentials of GnRH neurons. Application of KRGE (3 ${\mu}g$/${\mu}L$) under whole cell patch induced remarkable inward currents (56.17${\pm}$7.45 pA, n=25) and depolarization (12.91${\pm}$3.80 mV, n=4) in GnRH neurons under high $Cl^-$ pipette solution condition. These inward currents were not only reproducible, but also concentration dependent. In addition, inward currents and depolarization induced by KRGE persisted in the presence of the voltage gated $Na^+$ channel blocker tetrodotoxin (TTX), suggesting that the responses by KRGE were postsynaptic events. Application of KRGE under the gramicidin perforated patch induced depolarization in the presence of TTX suggesting its physiological significance on GnRH response. Further, the KRGE-induced inward currents were partially blocked by 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX; non-NMDA glutamate receptor antagonist, 10 ${\mu}M$) or picrotoxin (PIC; $GABA_A$ receptor antagonist, 50 ${\mu}M$), and almost blocked by PIC and CNQX mixture. Taken together, these results suggest that KRGE contains ingredients with possible GABA and non-NMDA glutamate receptor mimetic activity, and may play an important role in the endocrine function of reproductive physiology, via activation of $GABA_A$ and non-NMDA glutamate receptors in GnRH neurons.

The purpose of this study is to investigate the effect of water extract from Artemisiae Argi Folium (WAAF) on hepatotoxicity caused by acetaminophen (AAP) and acetaldehyde which are regarded as hepatotoxin. Artemisiae Argi Folium was known to have the antibacterial, immune-enhancing, and anticoagulative properties. In Korean Medicine, Artemisiae Argi Folium is supposed to be related with 'liver meridian' according to traditional medical theory. AAP and acetaldehyde reduce the intracellular production of hydrogen peroxide ($H_2O_2$) and nitric oxide (NO) production of human hepatocyte HepG2. The intracellular production of hydrogen peroxide ($H_2O_2$) was measured by dihydrorhodamine 123 (DHR) assay. NO production was measured with Griess test. WAAF increased the production of $H_2O_2$ and NO reduced by AAP and acetaldehyde in HepG2 cells. Therefore, It could be suggested that WAAF has the hepatoprotective activity against AAP and acetaldehyde.
