Objectives: The aim of this study was to report a 118-case series demonstrating the treatment of hypertension in a Korean medicine clinic and to evaluate the effect of Korean medicine. Materials & Methods: From 2006 to 2018, patients who visited a Korean medicine clinic for hypertension were investigated by studying changes in blood pressure before and after treatment with herbal medicine, acupuncture, and Uwhangchungsim-won. The average treatment period was 81.6 days. Results: After treatment with Korean medicine, the mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) of all patients decreased significantly (p<0.001). The SBP decreased from $148.9{\pm}10.3$ to $133.8{\pm}13.9$, and the DBP decreased from $91.3{\pm}7.5$ to $82.5{\pm}9.0$. After treatment with acupuncture or Uwhangchungsim-won, the patient showed decreased blood pressure but the differences were not statistically significant when compared with the non-treated group. Conclusions: This study shows the real situation of hypertension treatment in Korean medicine and indicates that Korean medicine could be one of the primary treatment for hypertension. However, this study had limitations, such as variations in the treatment periods, the frequency of acupuncture treatments, and the type of antihypertensive drugs. For further evaluation of the effectiveness of treatment for hypertension using Korean medicine, a well-designed study should be undertaken.

The peace movement in North Korea began during preparation of the National Peace Congress in March 1949. The North Korean government organized a support movement of world peace and sent national representatives to the World Peace Congress in Paris in April of that year. Unlike peace movements of western countries which were linked with anti-war or anti-nuclear weapons campaigns, the North Koreans used the nation-wide campaign as a mass practice for reunification in the Korean peninsula; the peace campaign was a useful tool in propagating the national good of reunification and for organizing the social utilities and activities of people so as to maximize their capacity. Under the slogan of world peace, the government would lead the public interest and capacity in the direction they wanted, and by so doing, the political, social, and cultural basis for the upcoming agenda could develop.

Catechin은 녹차에서 추출되는 폴리페놀의 주요성분으로 고혈압 및 동맥경화의 예방효과, 당뇨억제효과, 항산화작용, 항암작용 등에 직접 관여하는 물질이다. 본 연구에서는 태평양에서 제공받은 녹차 catechin을 이용하여 상피성 암세포주인 A549 (폐암)와 EATC (복수암)세포에 투여한 후 처리농도와 시간에 따른 변화를 비교, 관찰함으로써 녹차의 효과와 작용기전을 밝혀내는데 목적이 있었다. 본실험은 A549 세포와 EATC 세포를 배양한 후 녹차 catechin을 1, 10, 100, 500 μg/ml의 농도로 48시간 동안 처리하였고, 광학현미경, 공초점현미경, 전자현미경 등을 이용하여 세포의 구조적 변화를 확인하였으며 MTT분석, 전기영동, 유세포분석기 등을 사용하여 세포 손상정도를 파악하였다. A549 세포에서는 catechin 1 μg/ml와 10 μg/ml 농도에서는 대조군에 비하여 큰 변화를 관찰할 수 없었다. 100 μg/ml catechin을 처리하였을 때 세포내의 검은 과립들의 수가 증가하였고 층판소체의 손상이 나타났다. 세포주기의 장애가 나타나 DNA 합성전기에 있는 세포들의 수가 급격히 증가하였다. 500 μg/ml 농도에서는 층판소체와 사립체의 파괴가 심하게 나타났으며 세포생존율이 감소하였고 세포주기의 장애도 관찰되었다. EATC 세포에서는 catechin의 농도가 A549 세포의 경우보다 낮은 농도에서도 세포증식 억제 및 세포손상 효과가 나타났다. 10 μg/ml 농도에서도 세포의 위축과 생존율의 감소가 일어났으며 전기영동상에 괴사되는 세포들이 파악되었다. 100μg/ml catechin을 처리하였을 때 자연사의 형태학적 관찰, 전기영동, 유세포분석 등에서 자연사 과정에 있는 세포들이 많이 나타났다. 결과적으로 녹차 catechin을 배양한 상피성 암세포에 투여함으로서 세포의 생존율과 증식이 억제되었고 그 과정에서 괴사, 자연사, 세포주기의 장애 등이 관여하는 것으로 생각된다. 그러나 일련의 세포손상과정을 유도하는 데 있어 세포의 종류, 처리 시간, 농도에 따라 다소 차이가 있음을 확인하였다. Catechin is main component of polyphenol extracts from green tea, it is associated with prevention of hypertension and atherosclerosis, anti-diabetic effect, antioxidant, antitumor. The purpose of this research is to investigate the effect and its mechanism of green tea catechin on epithelial cancer cell lines in various concentrations and durations. For this study, epithelial cancer cell lines, A549 (lung cancer), EATC (Ehrlich-Lettre ascites tumor cell) were used. Inverted, light, confocal and electron microscopes were applied to find morphological changes. MTT assay, flowcytometric analysis, gel electrophoresis were used to compare severity of cellular damages to control after exposure to 1, 10, 100 and 500 μg/ml catechin for 48 hours. In the A549 cells, after 1 μg/ml and 10 μg/ml catechin treatments, there was no notable changes. However, exposure to 100 μg/ml catechin induced increase of cytoplasmic granules, destruction of lamellar body, inhibition of cell cycle, especially G0/G1. In the early phase of 500 μg/ml catechin administration, decrease of cell population, severe destruction of lamellar bodies and mitochondria, derangement of cell cycle were shown. In the EATC, such as those effects occurred after exposure to lower concentration of catechin than in that of A549 cells. After exposure of 10 μg/ml catechin, rounded-up cells and necrotic cells were found. Whereas, most of cells were under apoptotic changes-cytoplasmic condensation, nuclear fragmentation, cellular shrinkage, ladder pattern in the electrophoresis, when administrated 100 μg/ml catechin. These results suggested that exposure of catechin induced severe cellular damage and growth inhibition in dose- and time-dependent manner. And we confirmed that these effects of catechin were involved with apoptosis, necrosis and cell cycle arrest and were quite different according to cancer type. Therefore, much more research would be demanded before clinical application of catechin to human cancer therapy and this study would be the basic source for further study of green tea.
