The filter bank multicarrier modulation (FBMC) technique is one of multicarrier modulation technique (MCM), which is mainly used to improve channel capacity of cognitive radio (CR) network and frequency spectrum access technique. The existing FBMC System contains serial to parallel converter, normal QAM modulation, Radix2 inverse FFT, parallel to serial converter and poly phase filter. It needs high area, delay and power consumption. To further reduce the area, delay and power of FBMC structure, a new clock gating technique is applied in the QAM modulation, radix2 multipath delay commutator (R2MDC) based inverse FFT and unified addition and subtraction (UAS) based FIR filter with parallel asynchronous self time adder (PASTA). The clock gating technique is mainly used to reduce the unwanted clock switching activity. The clock gating is nothing but clock signal of flip-flops is controlled by gate (i.e.) AND gate. Hence speed is high and power consumption is low. The comparison between existing QAM and proposed QAM with clock gating technique is carried out to analyze the results. Conversely, the proposed inverse R2MDC FFT with clock gating technique is compared with the existing radix2 inverse FFT. Also the comparison between existing poly phase filter and proposed UAS based FIR filter with PASTA adder is carried out to analyze the performance, area and power consumption individually. The proposed FBMC with clock gating technique offers low power and high speed than the existing FBMC structures.

Objectives : We investigated the effects of Coptidis Rhizoma and Aconiti Lateralis Preparata Radix on the LPS(Lipopolysaccharide) ICV(intracerebroventricular) injection. Methods : We measured plasma corticosterone level and rectal temperature in mice induced by I.C.V. injection of LPS (100ng/mouse). Results : The results were as follows.. 1. The plasma corticosterone levels in CR-1(0.5g/kg), CR-2(1.0g/kg), CR-3(3.0g/kg) were not decreased significant comparing with the control group.(P<0.05) 2. The plasma corticosterone level in AR-1(0.5g/kg) was decreased significant comparing with the control group.(P<0.05), but AR-2(1.0g/Kg) and AR-3(3.0g/kg) were not decreased significant comparing with the control group.(P<0.05). 3. The rectal temperature in CR-1(0.5g/kg), CR-2(1.0g/kg), CR-3(3.0g/kg) was decreased significant comparing with the control group.(P<0.05) 4. The rectal temperature in AR-1(0.5g/kg), AR-2(1.0g/kg), AR-3(3.0g/kg) was not decreased significant comparing with the control group.(P<0.05) Conclusion : These data revealed that Rhizoma Coptidis might have no significant effect on inflammation stress and Aconiti Lateralis Preparata Radix(0.5g/kg/mouse) might have significant effect on inflammation stress.

This study was carried out to investigate the comparison of immunomodualtory effects of water-extracted Aconiti lateralis Preparata Radix(PR), Zingiberis Rhizoma(ZR), Cinnamomi Cortex(CC) and Evodiae Fructus(EF). The parameter examined to assess apparent immunomodulatory effect of the water-extracted PR, ZR, CC and EF included the regulation of Nitric oxide (NO). Also, ZR and EF represent the expression of Th1/Th2 type cytokine, the change of B cell phenotype. The water-extracted PR, ZR, CC and EF inhibited NO production and iNOS protein expression in LPS stimulated RAW 264.7 macrophage cells. In the Th1 and Th2 cytokine expression, the water-extracted ZR and EF induced IL-2, IFNr and IL-10 mRNA gene expression. Therefore, it seems that the water-extracted ZR and EF have a inducing effect of Th1 and Th2 type cytokines. In the Flow cytometry analysis, the water-extracted ZR and EF changed B cell phenotype (CD45R/B220), did NOT in PR and CC. The water-extracted PR, ZR, CC and EF have a reducing effect of immune suppression cause by Methotrexate (MTX), an agent of immune suppression. These results suggest that the immunomodulatory effects of the water-extracted ZR and EF may be, in part, associated with the inducing IL-2 and IFNr mRNA gene expression In and regulation of NO production in macrophage cells.

This study aimed at evaluating the preventive effect of Glycyrrhizae Radix and Glycine Semen Extract (GGE) against NAC intoxication. NAC is widely used pesticide in many countries and derivative of carbamats and GGE is well-known antidote to some kinds of toxicants which was referenced from oriental medicine text. The results obtained were as follows: 1) After injecting NAC (100,140 mg/kg), determined Ch.E activities decrease 44.77~50.86% for all experimental groups at one hour after exposure, and were gradually recovered in the course of time. 2) In toxicity test of GGE, there were no sign of death or poisoning up to 5000 mg/kg of GGE for p.o. in mice. From this, we suggest that the LD$_{50}$ of GGE would be above 5000 mg/kg. 3) The Ch.E activity in control group was 471.43 $\pm$ 4.85 luff, group I was 215.27 $\pm$ 23.13 IU/l, group II and group III were 304.03 $\pm$ 9.03 IU/l, 433.81 $\pm$ 21.73 IU/l, respectively. Compare to the control group with experimental group I, remarkable difference revealed (p< 0.01), but the Ch.E activities of group II and III were similar to those of control group. This is indicate that GGE possess a potent activity of recovering Ch.E. GGE had a very remarkable preventive effect on NAC toxicity, and it was able to know that Ch.E activity dramatically increased according to GGE dosage increasing. 4) When GGE and NAC were administered by p.o. simultaneously, LD$_{50}$ and confidence intervals of each group were as follows: the control group: 270 mg/kg, 234.99~310.23 mg/kg, group I and II (GGE 500 mg/kg, 1000 mg/kg by p.o.): 310 mg/kg, 271.69~353.71mg/kg, and 325 mg/kg, 285.09~370.50 mg/kg, respectively. In the comparison with the control group, the protective index was 1.1 and 1.2, respectively. From the above result, GGE has reactivation effect to decreasing Ch.E activity induced by exposure to NAC. Furthermore, GGE shows a preventive effect on NAC intoxication.

Objectives: This study presents a reversed-phase high-performance liquid chromatography- pulsed amperometric detection(RP-HPLC-PAD) method for the determination of puerarin and daidzin in Puerariae Radix extract and Chinese medicinal preparations. Methods: Chromatographic separation was performed using a 10% acetonitrile with a reversed-phase column(Unison UK-C18, $100mm{\times}2.0mm$ I.D.; $3{\mu}m$). The analyses were detected by pulsed amperometric detector(PAD) in alkaline conditions by combining with post-column NaOH solution. Geniposide was used as an internal standard. Results: The limit of detection(S/N=3) and the limit of quantification(S/N=10) were 0.025 ng, 0.075 ng for puerarin, and 0.05 ng, 0.15 ng for daidzin, respectively. The intra- and inter-day precisions(RSDs) were less than 6.5% and average recoveries of puerarin were 99.7-101.3% and those of daidzin were 101.0-102.8%. Conclusions: According to above results, we developed a determination method for puerarin and daidzin in Puerariae Radix with high sensitivity and selectivitely.

Osteoporosis is a major worldwide public health problem that poses a great economic burden to society. Puerariae Radix, the dried root of Pueraria lobata (Wild.) Ohwi, has been widely used in Asia. This study investigated the effects of Puerariae Radix (PR) on bone loss in ovariectomized (OVX) mice. C3H/HeN mice (10 weeks old) were divided into sham and OVX groups. The OVX mice were treated with vehicle, $17{\beta}-estradiol$ ($E_2$), PR (oral administration, 250 mg/kg/day) or PR (intraperitoneal administration, 50 mg/kg/every other day) for 6 weeks. Grip strength, uterus weight, serum alkaline phosphatase (ALP), estradiol concentration and osteoclast surface levels were measured. Tibiae were analyzed using microcomputed tomography. There were no significant differences in the degree of grip strength, body weight and uterine weight between OVX group and PR-treated group. As compared with the OVX group, the serum estradiol levels were significantly increased in the PR-treated group. PR (i.p.) significantly preserved trabecular bone volume, trabecular bone number, structure model index and bone mineral density of proximal tibiae metaphysic. The administration of PR lowered serum ALP and osteoclast surface levels in OVX mice, suggesting that PR can reduce the bone turnover rate in mice. The results indicate that the supply of PR can prevent OVX-induced bone loss in mice.

For the evaluation of anti-tumor activity of Korean Oldenlandia Herb (KOH) and Radix (KOR), our experiment was performed with methanol extracts of KOH and KOR. They did not shown any cytotoxicity against HT1080 cell lines. However, they effectively showed anti-metastatic activity through inhibition of the adhesion of HT1080 cells to gelatin, downregulated the expression of MMP2 and uPA and upregulated the expression of TIMP2. They also inhibited tube formation of HUVECs induced by bFGF. However, they did not affect DNA topoisomerase I activity. Simiarly, the T/Cs % in KOH and KOR treated mice were increased 134.9% and 171 %, respectively at 2500 mg/kg. These results suggest that KOH and KOR exert anti-tumor activity via anti-metastatic and anti-angiogenic activities. The further study for isolation of effective compounds and its exact mechanism and comparative study with Chinese Oldenlandia Herba will be required.

A rapid and practical HPLC assay was developed for quantitative analysis of saponins in Platycodi Radix. Seven saponin components in Platycodi Radix, i.e., deapioplatycoside E, platycoside E, deapioplatycodin D$_3$, platycodin D$_3$, polygalacin D$_2$, platycodin D$_2$ and platycodin D were successfully resolved on C18 column and detected by ELSD. Standard curves were linear over the concentration range 1 ${\sim}$2,000 ${\mu}$g/ml (r$^2$>0.992). Intra- and inter-day coefficients for variation of seven saponin components were < 10% and limit of quantification of them were around 0.7${\sim}$1.5 ${\mu}$g/ml, respectively. Using this method, contents of seven saponins in various plant materials under different cultivating conditions were estimated.

Objectives : 판람근(板藍根)은 십자화과에 속하는 대청(大靑) 또는 숭남의 근(根)을 건조한 것이다. 본 연구는 판람근(板藍根)이 청열해독(淸熱解毒)함에 근거하여, LPS로 활성화된 Raw264.7 cell에서 판람근(板藍根)과 그 성분중의 하나인 tryptanthrin이 염증매개물질에 미치는 효과를 살펴보고자 하였다. Methods : 세포생존율은 MTT, nitric oxide (NO)는 Griess reagent를 사용하여 측정하였으며, 각 단백질의 발현량은 Western blot 방법을 사용하였으며, cytokine 및 cyclooxygenase-2 (COX-2)는 ELISA방법을 사용하여 측정하였다. Results : LPS는 NO 및 prostaglandin E2 (PGE2)를 유의하게 상승시켰으며, 판람근(板藍根)추출물 (IRE) 및 tryptanthrin 은 이들을 유의하게 억제하였다. 그러나 판람근(板藍根)의 또 다른 성분인 indigo는 유의한 결과를 나타내지 못하였다. IRE와 tryptanthrin은 inhibitory kappa B alpha의 인산화를 억제하여, nuclear factor-${\kappa}$B (NF-${\kappa}$B)의 핵으로의 전위(轉位)를 억제하여, iNOS 및 cytokine을 억제하였다. IRE와 tryptanthrin의 PGE2 억제는, COX-2의 발현억제에서가 아니라, COX-2의 활성을 억제함에서 기인하였다. Conclusion : 이러한 결과는 판람근(板藍根)이 NF-${\kappa}$B pathway를 경유하여 iNOS의 발현 및 COX-2의 활성을 억제함을 나타내며, 이러한 판람근(板藍根)의 항염증효능은 일부 tryptanthrin의 작용에서 기인함을 시사한다.
