Daehwang (Rheum tanguticum) was extracted by methanol, and the antimicrobial activities of the extract, against some food hazardous microorganisms, were investigated by the paper disc method. The minimum inhibitory concentration (MIC) of the extract against the microorganisms was determined, and the extract components were analyzed by GC/MS. The Daehwang extract showed the strongest antimicrobial effect against P. aeruginosa. The MICs on S. aureus, P. aeruginosa and S. typhimurium were 250, 300 and 300mg/$m\ell$, respectively. In the methanol extracts from Daehwang, 120 different compounds were separated, with the extraction yield of the phenolic compounds being relatively high (29.85%). Substances with antimicrobial activity, such as 2-methoxy-phenol and 4-vinyl-2-methoxy-phenol were detected in the study.

We designed to investigate the relationship the cold-hot theory of herbology and body temperature in experimental model. we prepared four kinds of oriental medicine, which consisted of two cold herbs, Daehwang and Seokgo, and two hot herbs, Buja and Padu. Decrease of body temperature by cold exposure for 12 hour was not inhibited by four herbs oral administration for two weeks. Thermogenesis in mammals is an essential physiological function to maintain the body temperature. Mitochondrial uncoupling proteins(UCPs), which have a potential to generate heat by uncoupling oxidative phosphorylation, apper to play a crucial role in thermogenesis. Therefore UCP is commonly recognized as a key molecule in metabolic thermogenesis and its dysfunction contributes to the development of obesity. In these experiments, Daehwang water extracts inhibited the UCP1 mRNA expression increase by cold exposure in brown adipose tissue. But other herbs did not significantly influence on UCPs mRNA expression in white adipose tissue and seleus muscle tissue. Based on this experiment, we will try to clarify the effects of Daehwang water extracts on UCP1 expression and function.

Objectives This study was designed to report the effect of Samultang-gamibang(四物湯加味方) for insomnia caused by blood deficiency (syndrome) after excessive weight control treatment with herbal medication Methods This is a retrospective case report. We reviewed the patient's medical record after taking the patient's informed consent. Results After treatment, a patient feels calm and satisfaction emotionally as sleeping time has increased from 2hours to 6hours, the fatigue after sleeping has been reduced, and the quality of sleep has become better. Conclusions This case report suggests that Samultang-gamibang can be effective in improving sleep duration and quality if the patient suffers insomnia due to hyul-heo syndrome. Also the woman who have symptom of hyul-heo(血虛) after weight control through decreased food consumption, should bo-hyul(補血).

To evaluate the anti-obesity efficacy of Gamitaeeumjowi-tang consisting of Taeeumjowitang and Daehwang. Eleven male(n=4) and female(n=7), obesity patients were recruited by Tenten Diet Network from November 2005 to February 2006. All the subjects were treated with Gamitaeeumjowi-tang 3 times a day for 12 weeks. Weight, BMI, body fat weight, Total cholesterol, LDL, HDL, Triglycerides, GOT, GPT, and CT results were evaluated before and after the 12 week treatment. Weight, BMI, body fat weight, total cholesterol, triglyceride, and subcutaneous fat in upper and lower abdomen all showed significant decrease after 12 weeks of administration. Also Gamitaeeumjowi-tang showed no toxic effects based on liver function test. Taken together, The potentials of Gamitaeeumjowi-tang as a safe and effective treatment for obesity has been recognized through this study. Further large sample sized and double blinded randomized control trials are needed to fully confirm the findings of this study.

1. Objectives : This paper was written in order to understand the origin and changes of Galgeunhaegi-tang. 2. Methods : We analysis Galgeunhaegi-tang through pathology and new prescription in "Donguibogam(東醫寶鑑)", "Chobongwon(草本卷)", "Gabobon(甲午本)" and "Sinchukbon(辛丑本)" of "Dongyi Suse Bowon". 3. Results and Conclusions : We can find the first origin of Galgeunhaegi-tang in "Sinchukbon(辛丑本)" in "Donguibogam(東醫寶鑑)" which invelves Galgeunhaegi-tang in the categories of pestilence(瘟疫) and Yangmyeonggyeongbyeong(陽明經病). Also, we can find the origin in Jugoeng(朱肱)' Jojung-tang. Seungeumgalgeun-tang in the "Chobongwon(草本卷)" developed by a Galgeunhaegi-tang of "Gabobon(甲午本)", and Galgeunnabokja-tang in the "Chobongwon(草本卷)" developed by a Galgeunhaegi-tang of "Sinchukbon(辛丑本)". It is considered that Galgeunhaegi-tang of "Gabobon(甲午本)" solves heat depression(鬱熱), due to not throwing off, by using Galgeun(葛根) and Daehwang(大黃), and accompanied dryness(燥) by using Hangin(杏仁) and Sanjoin(酸棗仁) which moisten dryness(燥). It is considered that Galgeunhaegi-tang of "Sinchukbon(辛丑本)" solves heat depression(鬱熱) by using Galgeun(葛根) and accompanied dryness(燥) by using Gobon(藁本) which sets free dryness(燥).

Silkworms, which have recently shown promise as functional health foods, show functional differences between varieties; therefore, the need for variety identification is emerging. In this study, we analyzed the whole silkworm genome to identify 10 unique silkworm varieties (Baekhwang, Baekok, Daebaek, Daebak, Daehwang, Goldensilk, Hansaeng, Joohwang, Kumkang, and Kumok) using single nucleotide polymorphisms (SNP) present in the genome as biomarkers. In addition, nine SNPs were selected to discriminate between varieties by selecting SNPs specific to each variety. We subsequently created a decision tree capable of cross-verifying each variety and classifying the varieties through sequential analysis. Restriction fragment length polymorphism (RFLP) was used for SNP867 and SNP9183 to differentiate between the varieties of Daehwang and Goldensilk and between Kumkang and Daebak, respectively. A tetra-primer amplification refractory (T-ARMS) mutation was used to analyze the remaining SNPs. As a result, we could isolate the same group or select an individual variety using the nine unique SNPs from SNP780 to SNP9183. Furthermore, nucleotide sequence analysis for the region confirmed that the alleles were identical. In conclusion, our results show that combining SNP analysis of the whole silkworm genome with the decision tree is of high value as a discriminative marker for classifying silkworm varieties.

A new black seed coat soybean cultivar, 'Daeheug', was developed at the National Institute of Crop Science (NICS) in 2007. The breeding goal for black seed coat soybean is to develop the cultivar with large seed size, high yield, lodging tolerance, and resistance to disease such as soybean mosaic virus (SMV), and bacterial pustule. 'Daeheug' was selected from the cross between 'Daehwang' which had yellow seed coat, large seed size, and late maturity, and 'Milyang 79' which was lodging tolerant, and SMV resistant with medium seed size, black seed coat, and yellow cotyledon. The preliminary, advanced and regional yield trials for evaluation and selection of this cultivar were carried out from 2003 to 2007. It has determinate growth habit, purple flower, brown pubescence, brown pod color, black seed coat, yellow cotyledon, spherical flattened seed shape, oval leaf shape and large seed size (34.3 g/100 seeds). In maturity, 'Daeheug' was 2 days later than the check cultivar 'Ilpumgeomjeongkong'. In the seed quality such as isoflavone contents ($635{\mu}g/g$), and anthocyanin contents ($11.2m{\ell}/g$ of seed coat), 'Daeheug' was better than the check cultivar. It has good adaptability for cooking with rice in ratio of water absorption and seed hardness. Specially, it has good processability for soybean tea with 2.13 absorbance at 530 nm, scavenge activity of DPPH radical was high, and contents of total phenolics was $1,263{\mu}g/m{\ell}$. The average yield of 'Daeheug' was 2.26 ton per hectare in the regional yield trials (RYT) carried out in six locations of Korea from 2005 to 2007.
