Because the size of population was directly related to the power of the nation in the Chosun Dynasty, various efforts were exerted to maintain the size stable and the keys to the efforts were a high birth rate and a low death rate. However, in addition to wars, epidemic diseases had an enormous effect on the death rate. Particularly during the mid Chosun Dynasty, epidemic diseases were more prevalent than ever due to the abnormal climate called the little ice age. To cope with them, the government executed several medical relief policies and published medical books. In Chinese epidemiology, infectious diseases mean sicknesses caused by hot weather, but in Korean epidemiology, they indicate large-scale infectious sicknesses caused by both hot and cold weather. Therefore, as treatment methods for diseases from the cold were not applicable to the pathology of epidemic diseases, China developed separate epidemiology. In Korea, however, the main concern was how to prevent epidemic diseases, whether from hot or cold weather, that drove many lives into death. The characteristics of Korean epidemiology are as follows. First, whenever epidemic diseases were prevalent, in order to cope with them, translated medical books were promptly published including Ganibyeokonbang, Bunmunonyeokihaebang, Sinchanbyeokonbang, Byeokyeoksinbang and Byeokonsinbang. Second, those books were annotated in Korean so that people could read easily and accurately. Third, as an extension of the Hyangyak movement from the late Koryo Dynasty, Danbang was used a lot to treat and prevent epidemic diseases with less financial burden, and things obtainable easily according to individuals' situation were mentioned for anybody to overcome the emergent situation of epidemic diseases. Fourth, methods for praying to God were suggested for practitioners to work with sincere spirit and to keep themselves from epidemic diseases.

Objectives : To analyze symptoms of olfactory dysfunction caused by COVID-19 from a Korean Medical Perspective. Methods : Previous studies dealing with olfactory dysfunction accompanying COVID-19 were studied and analyzed for general characterization. Physiology and pathology of olfactory functions within the classical texts of Korean Medicine were collected and analyzed, through which symptoms of olfactory dysfunction in COVID-19 were examined. Results : Olfactory dysfunction manifested in high ratios in the early stages of confirmed COVID-19 cases, at times independent of other nasal symptoms such as blockage or discharge. There was a high chance of loss of taste being accompanied, while mental problems such as a tendency to have difficulty concentrating were present as well. In most cases, recovery took one to two weeks. From a Korean Medical perspective, physiology of olfactory function is closely linked to the Lungs, Ancetral Qi[宗氣], and the Heart, while its dysfunction could be explained by pathological factors such as Wind-Cold, Fire stagnation, Qi deficiency, Wind stroke, etc. Conclusions : In the context of external contraction disease[外感病], olfactory dysfunction could be caused by problems in the Lungs and Stomach that are responsible for breathing, or the Heart which is involved in recognizing and differentiating scent. General characteristics of COVID-19 imply it to be closely related to the Heart. In clinical application, overall symptoms need to be considered in diagnosis and treatment planning, after which further approaches could made to determine the problem to be of the Lung and Stomach, or of the Heart.

This paper aims to prove the effects of Squalene (SQ) on the cellular toxicity of 5-FU to the mouse which pretreated with SQ and then treated with 5-FU. The results of the group A (treated with only 5-FU) are as follows. The nucleus was destroyed at 24 hours and 48 hours group, however, somewhat repaired at 72 hours group. The dilated inner cavity and the irregular lamellae of the rough surfaced endoplasmic reticulum (RER) were observed continually until 72 hours group. The inner cavity of the smooth surfaced endoplasmic reticulum (SER) were dilated in all groups. However, the destroyed and the normal membrane were observed simultaneously at 72 hours group. The inner membrane of the mitochondria were almost repaired at 96 hours group. The results of the group B (treated with 5-FU and squalene) are as follows. The nucleus was a little influenced by the toxicity of 5-FU at 24 hours and 48 hours, RER were observed to keep the typical lamella structure of cisternae from 24 to 72 hours group, but inner cavity kept on dilating. In SER, inner cavity were also observed to flatten from 24 to 72 hours group. Mitochnodria were always shown normal. All cell organelles were simillar to those of normal groups at 96 hours. Accordingly, it can be said that the treatment of 50 prevents the cytotoxicity of 5-FU on cell organelles of liver cell and that is concerned with the formation of membrane system of cell organelles.

The suppressive effects of Platycodi Radix (Changkil: CK), the root of Platycodon grandiflorum A. DC (Campanulaceae), on the progress of acute carbon tetrachloride $(CCl_4)$-induced hepatic fibrosis were investigated in the rat. CK significantly suppressed $(CCl_4)$-induced hepatic necrosis and inflammation, as determined by the serum enzymatic activities of alanine and aspartate aminotransferase and serum tumor necrosis factor-${\alpha}$ levels, in dose-dependent manners. In addition, the increased hepatic fibrosis after acute $(CCl_4)$ treatment was suppressed by the administration of CK. CK also significantly prevented the elevation of hepatic ${\alpha}$ 1(I) procollagen (type I collagen) mRNA and ${\alpha}$ -smooth muscle actin (${\alpha}$ -SMA) expressions in the liver of $(CCl_4)$-intoxicated rats and also suppressed the induction of ${\alpha}$ -SMA and type I collagen in cultured hepatic stellate cells, in dose-dependent manners. These results suggest that the suppressive effects of CK against the progress of acute $(CCl_4)$-induced hepatic fibrosis possibly involve mechanisms related to its ability to block both hepatic inflammation and the activation of hepatic stellate cells.

To explore the possible cancer therapeutic application of "Bo-yang-hwan-oh-tang" (BH), a herbal medicinal recipe used for improvement of blood stasis, we have examined its direct cytotoxicity against tumor cell, and induction of cytotoxic activity of lymphocytes. Water extract of BH alone did not exhibit direct cytotoxicity to Yac-1 target cells even with high concentrations (10 mg/ml). By exposure for 3 days, BH did not induce any nonspecific cytotoxic activity of mouse spleen cells, either, when assessed in a 4 hr $^{51}Cr-release$ assay. However, when BH was added during CD3 stimulation of non-adherent spleen cells, non-specific CTL activity was markedly promoted in a dose dependent manner. In contrast, BH did not alter activated NK cell activity following IL-2 stimulation. These data suggest that BH does not induce but upregulates non-specific CTL effecter function and that activated NK cell does not respond to BH. For elucidation of the mechanism underlying this function of BH, time kinetic study for IL-2 production using ELISA was undertaken. IL-2 production following CD3 stimulation was significantly augmented and higher level of IL-2 is sustained over 3 days in the culture medium by BH treatment. Moreover, addition of exogenous IL-2 during CD3 stimulation resulted in a similar level of cytotoxicity between control and BH-treated culture. These data indicate that the BH-mediated upregulation of non-specific CTL activity is contributed by augmentation of IL-2 production. Our data imply the possible application of BH for combination therapy of cancer with non-specific activator.

To investigate effects of Taraxaci herbal-acupuncture on Adjuvant Arthritis in rats, the edema rate, the number of WBC, the quantity of total protein, albumin and globulin in the blood serum and histological test of the muscular tissue were measured in the arthritis part. 1. After elicitating arthritis of Sprague Dawely(SD) rats by injection of Freund's complets adjuvant for 2 weeks, saline was injected for the Exp. I group and Taraxaci herbal-acupuncture was injected for the Exp. II group during 30days. Selected point was $ST_{35}$ in both the groups. And then the volume of the paw were checked. The volume of paw was $0.84{\pm}0.14mm$ in the Exp. I group and $0.38{\pm}0.17mm$ in the Exp. II group, the swelling of the paw was restricted significantly in the Exp. II group(p<0.05) 2. The number of WBC was $10.34{\pm}0.14(10^3/ml)$ in the normal group and $37.47{\pm}5.46(10^3/ml)$ in the Exp. I group. It was $20.39{\pm}4.23(10^3/ml)$ in the Exp. II group. This fact showed that the group Exp. II was more effective than the Exp. I group in the treatment of arthritis(p<0.05) 3. The content of the total protein in the blood serum was $6.14{\pm}0.43g/dl$ in the normal group, $7.95{\pm}0.94g/dl$ in the Exp. I group, and $6.38{\pm}1.75g/dl$ in the Exp. II group. This fact showed that the group Exp. II was more effective than the Exp. I group in the treatment of arthritis(p<0.05) 4. The contents of albumin in the blood serum was $2.94{\pm}0.13g/dl$ in the normal group, $2.01{\pm}0.48g/dl$ in the Exp. I group. and $2.71{\pm}0.34g/dl$ in the Exp. II group. This fact showed that the group Exp. II was more effective than the Exp. I group in the treatment of arthritis(p<0.05) 5. The contents of globulin in the blood serum was $3.19{\pm}0.48g/dl$ in the normal group, $4.70{\pm}1.26g/dl$ in the Exp. I group. and $3.67{\pm}0.56g/dl$ in the Exp. II group. There was no significance in the serum globulin between Exp. II group and Exp. I group from the stastical analysis 6. In histological finding, because of severe inflammatory reaction, remarkably irregular tissue and large amount of inflammatory cells were found in the Exp. I group. But the Exp. II group showed small amount of inflammatory cells, the refrained inflammatory state and even recovering state. From these results, it is showed Taraxaci herbal-acupuncture refrain inflammatory reaction and muscular tissue necrosis in SD rats paw were induced by Freund's complete adjuvant

This thesis is written about the causes, the processes and the treatments of edema. It consists of 31 chapters. Covering 11 chapters, there are prescriptions and constructions. When one of the organs fails to work metabolizing water, you can have edema. It is the result of the accumulation of excess fluid under the skin. Edema most commonly occurs in the head facial, the palpebral portion, the feet and legs or all the body. Sometimes it is accompanied with ascites. There are three classifications in the thesis. First, according to the cause and the symptom of disease, it is divided into 5 types. Type 1. The swelling caused by the disorder of the lungs from the troubling wind. Type 2. The swelling caused by the weak spleen. Type 3. The swelling caused by abnormal condition between the kidneys and the lungs. Type 4. The swelling in abdomen caused by the weak kidneys. Type 5. The swelling (Yellow sweat) caused by the heat inside body as water outside. Second, the swelling and the abnormal symptom of five viscera. Third, the swelling accompanied with menstruation in female and with chilliness. In short, the original textbook is showed that the treatment of edema focuses on the cause and the region of fluid accumulation. When the swelling is in the upper body or the cause of diseaseis outside, the useless humidity can be expelled through sweating. On the other hand, when the swelling is in the lower body or the cause of disease is inside, it is pushed out by urination. In this book, the author presents further treatments. And these treatments are often cited by doctors after ages. Even one of them suggested that the swelling be divided by cosmic dual forces. In spite of many researches, it is too complicate for us to understand the writer’s intend. For that reason, comparing with other medical books and referring to guides explained by doctors, I have studied the textbook to help understand.

The purpose of this study is to investigate the blood pressure reducing effect of Qi-Ju-Di-Huang-Wan (QJDHW) in adults with essential hypertension by using methods of systemic review and meta-analysis. Major search engines, such as PubMed, EMBASE, Cochrane library, Web of Science, CNKI, CiNii, J-STAGE, KISS, NDSL, RISS, OASIS, DBpia and so on, were used. The search period we used is from the start date of the search engine to October 30, 2016 and no language limits were placed. Randomized controlled trials using QJDHW in adults with essential hypertension were searched and extracted by two independent researchers. Meta-analysis was performed on outcome variables of the total effective rate (TER), systolic blood pressure (SBP) and diastolic blood pressure (DBP). Risk of bias (RoB) of Cochrane was used to assess methodological quality. Thirteen studies were finally selected. We observed that the combined treatment of QJDHW and antihypertensive drug had 3.6 times the odds ratio of TER for blood pressure lowering than a single use of an antihypertensive drug. Additionally, mean differences of SBP and DBP were -8.88 mmHg (95% Confidential Interval (CI) -12.77 mmHg, -5.00 mmHg, P<0.00001), -7.09 mmHg (95% CI -9.93, -4.25, P <0.00001), respectively. Single use of QJDHW did not reduce blood pressure more than an antihypertensive drug. All items of RoB were unclear and the methodological quality was low. Our analysis suggests that the combination of QJDHW and antihypertensive drugs may be more effective in reducing blood pressure than a single antihypertensive drug. But due to low methodological quality, careful interpretation will be needed and systematic long-term clinical trials will be required.

Chijabaegpi-tang (CHG) is an oriental herbal medicine that has been used for its various pharmacological effects, which include anti-inflammatory, anti-oxidant and immunoregulation activities. In the present study, we investigated which skin inflammations are involved in the $TNF-{\alpha}/IFN{\gamma}$-induced HaCaT cells. We investigated the suppressive effect of CHG on $TNF-{\alpha}/IFN{\gamma}$-induced HaCaT cell production of the following chemokines: macrophage-derived chemokine (MDC)/CCL22; regulated on activation, normal T-cell expressed and secreted (RANTES)/CCL5; and interleukin-8 (IL-8); thymus and activation-regulated chemokine (TARC)/CCL17. The pre-treatment of HaCaT cells with CHG suppressed $TNF-{\alpha}/IFN{\gamma}$-induced nuclear transcription factor kappa-B ($NF-{\kappa}B$). In addition, CHG inhibited $TNF-{\alpha}/IFN{\gamma}$-induced phosphorylation of ERK and p38. $TNF-{\alpha}/IFN{\gamma}$ suppressed the expression of skin barrier proteins, including filaggrin (FLG), Involucrin (IVL) and loricrin (LOR). By contrast, CHG restored the expression of FLG, IVL and LOR. Taken together, our findings suggest that CHG could be a therapeutic agent for prevention of skin disease, including atopic dermatitis.
