A Study on Thought of Tea of Hanjae Yi-mok＇s Da-bu     

HC Lee  WS Jang 《茶叶》2013,(4):528-531

The Da-bu of Hanjae Lee mok （1471-1498） is known as an original masterpiece,which is predominantly documented in Korean tea books.He had always spared no effort to put Confucianists＇ theories and thoughts into practice during his 28-year career.Da-bu tea magnificently reflected his concepts of Confucianism in conjunction with tea-drinking activities.The main contents of Da-bu have included written authors,tea species and production,landscape of tea cultivation,tea plants and leaves,ways of tea-drinking and three-grade tea,tea song of seven cups,5 merits and 6 moralities of tea,benefits of tea-drinking,tea comprehension,etc.According to the views of contents,tea of Hanjae Leemok is the only partner with which we can share life and it can also be beneficial to healthy diets.Not only does it have become part of our daily life,but also be a medicine for our physical and mental disease.He composed the tea song of seven cups,which sufficiently expressed a real practice of the pursued ideal state of Confucianism and Taoism.He also promoted a drinking tea for health enrichment of Confucianists.According to the analytical results of Da-bu,Hanjae＇s tea has recognizably become the personally real practice of Confucianism and state.He had reached the enlightenment for the state of birth and death.After consuming tea,his body and mind immediately changed to the state of joys and wonderland,and also he illustrated that this feeling is not a one-off state,it always comes out whenever drinking.Therefore,based on Hanjae Lee mok,tea drinking is not only the regiment for healthy benefits,but also it is a training method,＂ Dado in My Heart＂,for individuals to train their mind,body,and morality.  相似文献

Summary Monoclonal antibodies (MAb) specific to potato virus Y (PVY) were obtained from hybrid cells produced by fusion of a non-secreting myeloma cell line with spleen cells from BALB/c mice immunized with isolate Bintje PVY^o. Six MAb were characterized. The reactions of the MAb have been assayed by indirect double-antibody sandwich enzyme-linked immunosorbent assay (ELISA-IDAS) against forty-nine PVY isolates and other potyviruses, representative of different potato areas in the world. All MAb reacted to at least some isolates in group O+C in ELISA-IDAS. One MAb did not react to any group N isolates. MAb 10E3 reacted to all isolates tested. Using standard double-antibody sandwich enzyme-linked immunosorbent assay (ELISA-DAS), two MAbs did not react to any isolates, one reacted to some isolates in group O+C and MAb 10E3 reacted to all isolates but two in group C. A mixture of MAb 10E3 and 1E10 detected all isolates in ELISA-DAS and sensitivity was improved over that obtained with polyclonal antibodies from antisera.  相似文献   

First in vitro isolation of Besnoitia besnoiti from chronically infected cattle in Germany

Besnoitia besnoiti was in vitro isolated during the first recorded outbreak of bovine besnoitiosis in Germany. Molecular characterization of the new isolate, named Bb-GER1, revealed almost 100% identity with other B. besnoiti isolates obtained in Portugal, Spain, Israel or South Africa, when partial sequences of the 18S ribosomal RNA gene, of the internal transcribed spacer 1 and of the 5.8S RNA gene were compared. Cystozoites obtained from skin tissue of one bull were infectious for γ-interferon knockout (GKO) mice by intraperitoneal (ip) inoculation. Tachyzoites were detected in the peritoneal cavity, spleen, liver and lung of the mice 5 days post-infection. The parasite could be maintained in GKO mice by ip inoculation for at least 5 passages. Peritoneal washings containing tachyzoites were obtained from infected mice and used to infect five cell lines (Vero, MARC-145, NA42/13, BHK₂₁, KH-R). The best growth of tachyzoites was observed in BHK₂₁ cells, but replication occurred to a smaller extent also in MARC-145, NA42/13 and KH-R cells. Subsequent comparative analyses revealed that after direct infection of these cell lines with cystozoites derived from bovine skin, the growth was best in NA42/13 cells. Considerable replication was also observed in the BHK₂₁ and KH-R cell lines. Our observations on the growth characteristics of Bb-GER1 partially contrast those for other isolates. The preferential growth in particular cell lines may be characteristic for particular B. besnoiti isolates. A potential association between growth properties and differences in virulence remains to be established. This is the first in vitro isolation of B. besnoiti from cattle in Germany.  相似文献
