This paper confirmed the effect of Baekho-tang(白虎湯) on psoriasis patient diagnosed with Yangmyung-Yeoljeung(陽明熱證). We treated patients with psoriasis classified as Yangmyung-Yeoljeung(陽明熱證) according to Shanghanlun(傷寒論) with Baekho-tang(白虎湯). Two patients was treated with Baekho-tang(白虎湯) for 18 days and 75 days, respectively. Baekho-tang(白虎湯) used in the treatment consisted of Gypsum Fibrosum 16g, Oryza semen 12.5g, Anemarrhena Rhizoma 6g and Glycyrrhizae Radix 2g. The severity of psoriasis was evaluated by PASI(psoriasis area severity index) and pictures. Also we checked the change in Pruritus by VAS(visual analogue scale). After the Baekho-tang(白虎湯) treatment, the PASI of 2 patients decreased from 13 to 2.8 and from 10.8 to 0.8 respectively. In addition, VAS of 2 patients diminished from 10 to 3 and from 8 to 1 respectively. Moreover, no side effects were observed. We received effective results by giving Baekho-tang to Psoriasis patients with sweaty, dry mouth, and heating sensation. Anti-inflammatory, antipyretic effects and immunomodulatory functions of Baekho-tang(白虎湯) could lead to improvement of psoriasis.

Herbal medicines have been utilized to treat a variety of diseases, including cancer. Several species of the family rubiaceae have been reported to have antitumor activity. In this study, we report the cytotoxicity and antitumor activity exhibited dy the methanol extracts prepared from Rubia radix (RRME), Uncaria gambir (UGME) and Oldenlandia diffusa (ODME) (family: Rubiaceae) against human promyleloid leukemia cell line, HL-60. The cytotoxicity of RRME (2~20 ${\mu}g/ml$), UGME (20~200 ${\mu}g/ml$) and ODME (20~200 ${\mu}g/ml$) were assessed dy the MTT reduction assay. IC50 values for RRME, UGME and ODME were 11.0, 99.5 and 106.1 ${\mu}g/ml$, respectively. When the HL-60 cells were treated with RRME (10 ${\mu}g/ml$), UGME (120 ${\mu}g/ml$) and ODME (140 ${\mu}g/ml$) for 24 h, several apoptotic characteristics such as DNA fragmentation and morphologic changes were observed. Furthermore, flow cytometric analysis was peformed to determine the percent of apoptotic cells. The poupulation of sub-G1 hypodiploid cells was increased 37.49% in RRME treatment, 12.49% in UGME treatment and 7.21% in ODME treatment compared with untreated control cells (2.64%). To further confirm apoptotic cell death, we assayed caspase-3, -8 and -9 activities in RRME, UGME and ODME-treated cells. After treatment of RRME, UGME and ODME for 12 h, caspase-3, -8 and -9 activities significantly increased.compared to untreated control cells. These results show that RRME, UGME and ODME induced apoptotic cell death in HL-60 cells and may have a possibility of potential antitumor activities.

The aim of this study was to discover whether Yukmijihwangtang which was added Plygalae Radix, Acori graminei Rhizoma, has antioxidant effects on aged senescence-accelerated mouse (SAM) P8. The control group used 12 months old SAM P8 and the experimental group was treated with Yukmijihwangtang extracts from 8 to 12 months old. In the liver, the MnSOD of the control group were approximately 11% higher than that of the experimental group treated with herbal extracts, but CuZnSOD activities of the experimental group were approximately 20% higher than that of the control group. The catalase activities of the experimental group was approximately 67% higher than that of the control group. The hepatocytes, in the control group compared with the experimental group, contained the dilated cisternae of rough endoplasmic reticulum and the abnormal mitochondira which had electron-dense matrix and indistinguishable cristae. The inner cavity of the smooth endoplasmic reticulum were slightly dilated, and a number of vacuoles and transitional vesicles occured in of the hepatocytes of the control group. These results suggest that the herbal extract has an antioxidant effects on the liver of SAM P8.

UWB(Ultra Wide Band)는 차세대 무선통신 기술로 무선 디지털펄스라고도 한다. GHz대의 주파수를 사용하면서도 초당 수천~수백만 회의 저출력 펄스로 이루어진 것이 큰 특징이다[1]. 기존 무선통신 기술의 양대 축인 IEEE 802.11과 블루투스 등에 비해 속도와 전력소모 등에서 월등히 앞서고 있으며, SoC(System on a Chip)의 저전력 구현에 대한 연구가 활발히 진행되고 있다. OFDM은 크게 FFT(Fast Fourier Transform) 블록, Interpolation /decimation 필터 블록, 비터비 블록, 변복조 블록, 등화기 블록 등으로 구성된다. 고속 시스템에서는 대역효율성이 우수한 OFDM(Orthogonal Frequency Division Multiplexing) 방식을 사용하고 있으며, OFDM 전송방식은 직렬로 입력되는 데이터 열을 병렬 데이터 열로 변환한 후에 부반송파에 실어 전송하는 방식이다. 이와 같은 병렬화와 부반송파를 곱하는 동작은 IFFT와 FFT로 구현이 가능한데, FFT 블록의 구현 비용과 전력소모를 줄이는 것이 핵심사항이라고 할 수 있다. 기존논문에서는 OFDM용 FFT 구조로 단일버터플라이연산자 구조, 파이프라인 구조, 병렬구조 등의 여러 구조가 제안되었다[2]. 본 논문에서는 Radix-8 FFT 알고리즘 기반의 New partial Arithmetic 저전력 FFT 구조를 제안하였다. 제안한 New partial Arithmetic 저전력 FFT구조는 곱셈기 대신 병렬 가산기를 이용 하여 지금까지 사용되는 FFT 구조보다 전력소모를 줄일 수 있음을 보였다.

To differentiate the quality of Korean ginseng from those of other habitats, the quantitative analysis of free amino acids(FAA) and total amino acids(TAA) in addition to ginsenoside Rb1 and Rg1 was carried out using amino acid analyzer and HPLC, respectively. FAA pattern in Korean ginseng was much different from that of Panax notoginseng. The difference in total content of FAA was also found that Korean ginseng contained 26.3-39.8mg/g while Panax notoginseng contained 6.5mg/g. This FAA content had a tendency to increase with the age of radix. The contents of FAA and TAA in Korean ginseng(6 years old) from Kumsan were shown to be the highest than other ginseng origins tested. The content in the 6 years Panax ginseng from China was about same with that of 4 years Korean ginseng of Kumsan. However, regarding to gisenoside Rbl and Rg1, which have been accepted as the characteristic components of Panax ginseng-Panax notoginseng showed considerably higher content than those of any other ginseng origin.

Previously, wogonin (5,7-dihydroxy-8-methoxyflavone) was found to suppress proinflammatory enzyme expression including cyclooxygenase-2 (COX-2), contributing to in vivo anti-inflammatory activity against skin inflammation. However, the detailed effect on each skin cell type has not been understood. Therefore, present investigation was carried out to find the effect of wogonin on inflammation-associated gene expression from skin fibroblasts in culture using reverse transcriptase-polymerase chain reaction. As a result, it was found that wogonin (10 - 100 ${\mu}$M) clearly down-regulated COX -2 expression from NIH/3T3 cells treated with 12-O-tetradecanoylphorbol 13-acetate, interleukin-1${\beta}$ or tumor necrosis factor-a. But, the expression levels of COX-1, interleukin-1${\beta}$ and fibronectin were not significantly affected. This finding was well correlated with significant reduction of prostaglandin E$_2$(PGE$_2$) production by wogonin. As a comparison, NS-398 (selective cyclooxygenase-2 inhibitor) did not suppress COX -2 expression and other gene levels, while PGE$_2$production was potently reduced at 0.1 - 10 ${\mu}$M. All these results suggest that COX -2 down-regulation of skin fibroblasts may be, at least in part, one of anti-inflammatory mechanisms of wogonin against skin inflammation.
