  • This is a historical study of the tea culture and its manners after checking the origin of the tea culture in Korea. Also I created the Blooming Lotus Pond Tea which can be utilized in various meetings or at homes in connection with the tea culture and etiquette by studying good manners, clothing and light refreshments in 'Kyucongyogyul' by Lee-E, 'Karyejibramdo' by Kim Jang-Seng and other books of the Chosun Dynasty. I created the Blooming Lotus Pond Tea by referring to the tea-ceremonies described in the poems by Hong Inmo, his wife, Lady Suh, and her descendants. They can be better harmonized with the modem tea culture rather than the strict procedures of traditional court ceremonies or marriage, funeral, and other formal tea ceremonies. About the costumes of the nobilities, that is especially referred to Kyukmongyogyul by Lee-I of the Chosun Dynasty for the etiquette, also 'The Living Manners' by Professor Lee Gilpyo and Choi Baeyong. In addition, the tea-food is made based on 'the five elements'. The Blooming Lotus Pond Tea is made of frozen lotus flowers and prepared in the lotus formed broad-rimmed tea-utensils and supposed to be shared with family members or guests. It's recommended to hold a poetry-party with a tea-party. At present, this kind of daily tea ceremony is being developed at homes. It'll be desirable if it could recreate the traditional way as a ceremonial tea culture. In that case, it'll regain the quality of the traditional etiquette by harmonizing tea culture and manners. Such a tea culture can contribute to the quality of people's ordinary life and the identity of our country.

  • Various types of tea are consumed as a popular beverage worldwide particularly in Asian countries such as Korea, China, and Japan. The purpose of this study was to investigate the mineral contents, antioxidant properties and anticancer activity of Yak-Sun tea that is prepared by six oriental medicinal herbs. The results of the mineral contents were as follows; Ca, Mg, and Na contents were higher than those of green tea, whereas Fe, P, and K contents were lower than those of green tea. The total phenolics and flavonoid content of the Yak-Sun tea were higher than those of green and black teas. The $IC_{50}$ values of DPPH radical, hydroxyl radical, hydrogen peroxide radical scavenging of Yak-Sun tea were 0.78, 1.58, and 2.04 $mg/m{\ell}$, respectively, whereas the radical scavenging values of ${\alpha}$-tocopherol was 0.06, 0.05, and 0.09 $mg/m{\ell}$, respectively. When cancer cells were treated with Yak-Sun tea, the anticancer activity increased in a dose dependent manner. HCT116 colon cancer cell lines were dramatically increased, as compared to other cancer cell lines, such as MCF-7, H460, and MKN45 cell lines. The results of this study demonstrated that Yak-Sun tea could function as a tea to enhance health conditions for antioxidant and anticancer activity.

  • This paper investigated monthly meal composition and type of foods prepared for Dalye (ancestor rituals) over a period of 1 year based on the records in Sakmangdalye-deungnok and reviewed the ingredients for Dalye foods. From the results of our survey, 19 to 20 dishes were served in Sakmangdalye. 24 to 25 different foods were served in Sakdalye. Foods for Sakdalye consisted of Silkwa, Jogwa-Gwapyun, Jeongkwa or Suksilkwa, Hwachae-Sujeonggwa, Tteok, Cho, Jeonyueo, Sugyuk, Jjim, Hwe, Po, Sikhye, Tang, main dish-Guksu or Mandu, and Jang. Ingredients used in Sakmangdalye were recorded in a very integrated and simple manner in Sakmangdalye-deungnok. All ingredients were categorized into three groups: Kwasil (Fruits), Byeongmisikseung (Rice cakes etc.), and Muyeok (purchases). Sakmangdalye-deungnok was helpful in consulting dishes and ordering ingredients when a table for Dalye was set. Moreover, it was written simply enough so those who were in charge of preparing food could easily understand. This paper establishes Sakmangdalye-deungnok as one of the key materials for Royal Cuisine.

  • This study was conducted to investigate the chemical composition and biological function of tea made from mountain-cultivated ginseng leaves. The antioxidant activities of tea made from mountain-cultivated ginseng leaves were determined by measuring their electron-donating ability based on their DPPH and nitrite-scavenging ability. The electron-donating abilities of tea made from mountain-cultivated ginseng leaves (500 and 1,000 ppm) as determined by DPPH assay were 45.6 and 85.1%, respectively. The nitrite scavenging ability of tea made from mountain-cultivated ginseng leaves (500 and 1,000 ppm) at pH 6.0 were 32.8 and 51.4%, respectively. Furthermore, the nitrite scavenging activity increased in a dose-dependent manner at all pH values. The effects of tea made from mountain-cultivated ginseng leaves on Male Sprague-Dawley rats were also evaluated. To accomplish this, the rats were divided into three groups (A: normal diet group, B: high fat diet group and C: high fat diet supplemented with tea made from mountain-cultivated ginseng leaves group). The anti-obesity effects of tea made from mountain-cultivated ginseng leaves were then evaluated. The serum total lipid, total cholesterol and triglyceride contents in C group were lower than those of B group; however, these differences were not statistically significant. The HDL-cholesterol content was significantly higher in the C group than in the other groups. Taken together the results of this study suggest that tea made from mountain-cultivated ginseng leaves possesses antioxidant activity and improves lipid metabolism.

  • Intracellular calcium concentration ($[Ca^{2+}]_i$) may play a crucial role in a variety of neuronal functions. Here we report that in primary culture of mouse cerebellar granule cells nicotinic acetylcholine receptors (nAChRs) are expressed in a specific developmental stage and involved in the regulation of intracellular calcium homeostasis. Nicotine-mediated calcium responses were measured using $^{45}Ca^{2+}$ or fluorometrically using the calcium-sensitive fluorescent dye fura-2. Maximal uptake of $^{45}Ca^{2+}$ evoked by nicotine in mouse cerebellar granule cells were revealed $8{\sim}12$ days in culture. In contrast, nicotine did not alter the basal $^{45}Ca^{2+}$ uptake in cultured glial cells. In cerebellar granule cells nicotine-evoked $^{45}Ca^{2+}$ uptake was largely blocked by the NMDA receptor antagonists. Glutamate pyruvate transaminase (GPT). which removes endogenous glutamate, also prevented nicotine effects, implying the indirect involvement of glutamate in nicotine-mediated calcium responses. Fluorometric studies using fura-2 showed two phases of nicotine-evoked $[Ca^{2+}]_i$ rises: the initial rising phase and the later plateau phase. Interestingly, the NMDA receptor antagonists and GPT appeared to inhibit only the later plateau phase of nicotine-evoked $[Ca^{2+}]_i$ rises. The present results imply that nicotine mediated $^{45}Ca^{2+}$ uptake and $[Ca^{2+}]_i$ rises are attributed to the calcium fluxes through both nAchRs and NMDA receptors in a time-dependent manner. Consequently, nAChRs may play an important role in neuronal development by being expressed in a specific developmental stage and regulating the intracellular calcium homeostasis.

  • This article is to present that the research on the Mudang Gut Chum should be within the context of the performance of Mudang Gut and examines its meanings and implications with focus on Seoul Mudang Gut Chum and Hwanghae-do Mudang Gut Chum. Seoul and Hwanghae-do Mudang Gut Chums do not exist in the form of simple dance or movement. They feature continuity while serving the function of revealing the existence of spirit and sometimes show the process of the spirit joining the Gut ritual, which means that the Mudang Gut Chum should not be understood as the dance itself only. Instead, care attention should be paid to the status of the tune of Gut where the dance is placed, relationship between the gut and the spirit, and the flow of narrativity. Also, the Mudang Gut Chum has a lot to do with the tune. Looking at the Mudang Gut Chum simply focusing on dancing steps, and the movement of feet and/or hands fails to gain an accurate understanding of the fundamentals of the Mudang Gut Chum. Closely connected to the tune, which is also associated with the grade of the spirit, the dance shows a variety of performances conducted by entering the Gut ritual of the spirit. In that respect, complex views on the Mudang Gut Chum are required. The same applies to the hereditary shaman Mudang Gut as well. The Korean Mudang Gut Chum has a slight difference between the Gangshinmu gut and the hereditary gut but is in basically the same aspect. The Gut Chum holds its meaning in the flow of gutgeori (tune or dance performed during exorcism, a shaman song) and delivers its own meaning in connection with the tune. It is definitely meaningful to focus on the individual movements of a dancing shaman but one should be able to derive the network of meanings that such movements have within the performance of the gutgeori, which means that intensive studies on the field performance and circumstances should be completed before studying the Mudang Gut Chum. In addition, the Mudang Gut Chum discloses the characteristics of the performance group. The Mudang Gut Chum exists in a complex manner. With respects to the status of the spirit, it shows the characteristics of the performance group. It represents the progress of Gut while closely connected with the tune. Therefore, the way of describing the Mudang Gut Chum should be far more than just simply keeping the dance notations. With this in mind, one should investigate and record the Mudang Gut Chum.

  • Background: Epigallocatechin-3-gallate (EGCG) is the major catechin in green tea, and has shown antiproliferative, antiangiogenic, antimetastatic and cell cycle pertubation activity in various tumor models. Hypoxia can be induced because angiogenesis is insufficient for highly proliferating cancer. Hypoxia-inducible factor-1$\alpha$ (HIF-1$\alpha$) and its downstream target, vascular endothelial growth factor (VEGF), are important for angiogenesis, tumor growth and metastasis. The aim of this study was to determine how hypoxia could cause changes in the cellular phenomena and microenvironment in a non-small cell culture system and to examine the effects of EGCG on a HIF-1$\alpha$ and VEGF in A549 cell line. Methods: A549 cells, a non-small cell lung cancer cell line, were cultured with DMEM and 10% fetal bovine serum. A decrease in oxygen tension was induced using a hypoxia microchamber and a $CO_2-N_2$ gas mixture. Gas analysis and a MTT assay were performed. The A549 cells were treated with EGCG (0, 12.5, 25, 50 ${\mu}mol/L$), and then examined by real-time-PCR analysis of HIF-1$\alpha$, VEGF, and $\beta$-actin mRNA. Results: Hypoxia reduced the proliferation of A549 cells from normoxic conditions. EGCG inhibited HIF-1$\alpha$ transcription in A549 cells in a dose-dependent manner. Compared to HIF-1$\alpha$, VEGF was not inhibited by EGCG. Conclusion: HIF-1$\alpha$ can be inhibited by EGCG. This suggests that targeting HIF-1$\alpha$ with a EGCG treatment may have therapeutic potential in non-small cell lung cancers.
