Ethyl ether fractions of Ferula Resina(EFR) and Lithospermi Radix(ELR) and hexane fraction of Salviae miltiorrhizae Radix(HSR) exerted an inhibitory effect on cell adhesion of A549 to extracelluar matrix most effectively in vitro cell adhesion assay. Thus, with above fractions for the evaluation of antitumor activity, T／C% was monitored in ICR bearing S-180 and for antimetastatic effect, pulmonary colonization assay, weight of organs, changes of WBC and platelet were studied. In pulmonary colonization assay incidence rate to control was 73 % 42 %, 14 % in ELR, HSR and EFR-treated groups repsectively. Gain of lung weight was significantly inhibited in all groups while spleen weight was significantly reduced only in SMR group, but no changes in kidney and liver as compared with control. Number of platelet was significantly increased in all groups to normal range as compared with thrombocytopenic contol. WBC was significantly reduced only in LR group. These results suggest that ethyl ether fraction of Ferula Resina has more effective antimetastatic activity.

Recently, it has been found that Asiasari radix showed a hypopigmenting effect on melanogenesis through activation of mitogen-activated protein kinase (MEK)/extracellular signal-activated kinase (ERK) in B16F10 melanoma cells. However, the hypopigmenting effect of A. radix on the $\alpha$-melanocyte stimulating hormone ($\alpha$-MSH)-stimulated melanogenesis has remained unknown. The purpose of this study was to investigate the inhibitory mechanism of the partially purified A. radix (PPAR)-induced hypopigmentating effects on $\alpha$-MSH-stimulated melanogenesis in B16F10 mouse melanoma cells. PPAR strongly inhibited tyrosinase activity and leads to decreased melanin synthesis in $\alpha$-MSH-stimulated B16F10 melanoma cells. PPAR also decreased the $\alpha$-MSH-induced over-expression of the melanogenic enzymes, tyrosinase, tyrosinase-related protein (TRP)-1, dopachrome tautomerase (Dct) and microphthalmia-associated transcription factor (MITF). We further showed that PPAR inhibits $\alpha$-MSH-induced melanogenesis via phosphorylation of MEK/ERK and PI3K/Akt, and that their activation was blocked by MEK inhibitors, PD98059 and PI3K inhibitors, LY294002 in $\alpha$-MSH-stimulated B16F10 melanoma cells. These results suggest that PPAR inhibits $\alpha$-MSH-induced melanogenesis by activation of MEK/ERK and PI3K/Akt through MITF degradation, which may lead to down-regulation of tyrosinase.

Scutellaria baicalensis $G_{EORGI}$ (Scutellariae Radix) has been used to clear heat and to dry dampness in the stomach or intestines, which manifests as diarrhea or dysenteric disorder. In this study, we investigated the effective preparation of active components in Scutellariae Radix using the methods of solvent extraction and absorption fractionation for the development of new functional food or pharmaceuticals. The marker substances, baicalin, baicalein, wogonoside, and wogonin were directly isolated from the Scutellariae Radix. There chemical structures were elucidated by spectroscopic analysis. The Scutellariae Radix was extracted with hot water. To enhance yield of flavonoids in Scutellariae Radix, the hot water extract was dissolved in ethanol with concentration dependent manner. The precipitates were separated using centrifugal techniques at 10,000 rpm. Supernatant liquid was applied to the HPLC for quantification of major compounds. Separately, the hot water extract was absorbed on Diaion HP-20 resin. And then, the absorbed fraction was eluted with methanol for HPLC. The contents of baicalin, baicalein, wogonoside and wogonin in different treatment methods were analyzed by HPLC. Total amount of four major components were 16.9% in 50% ethanol extract, 21.7% in 70% ethanol extract, 20.5% in 90% ethanol extract, and 39.3% in absorbed fraction of Diaion HP-20 resin. In these results, we found that resin absorption method is suitable for the extraction of enriched flavonoids from Scutellariae Radix.

Physiological effects in SAM P6 and Rl by administration of Cervus cornu, Astragali Radix, Rehmanniae Radix, and Angelicae Radix extracts were screened to know in vivo activities of each extracts. We measured complete blood cells (CBC) such as aBC, HGB, and HCT using coulter's method. Plasma concentrations of albumin, glucose, alkaline phosphatase, calcium, creatinine, inorganic phosphate, urea and total iron ere also analyzed using biochemical clinical autoanalyzer. Plasma concentrations of cortisol, total T$_3$, and total T$_4$ were measured by chemiluminescent immunoassay methods. At 12 weeks after birth, Cervus conu or Astragali Radix or Rehmanniae Radix extracts were given 5 g/Kg.day p.o. for 0,7,14,21, and 30 days each in both SAM Rl and SAM P6. Angelicae Radix study was done the same as the others except the mice were 16 weeks after birth. The RBC, HGB, and HCT levels after administration of Astragali and Rehmanniae were elevated in SAM Rl, but those in Cervi study were increased in SAM P6 the most. Decreases in alkaline phosphatase concentration of SAM Rl and P6 after Cervi administration were detected. Total plasma iron concentration was decreased by Angelicae administration in SAM P6. In general, Angelicae and Rehmanniae stimulate increases in cortisol, but total T$_3$ and T$_4$ levels were also elevated by all these extracts. In conclusion, these herval medicine extracts help hematopoiesis in SAMs through probably different mechanisms.

Objective : Acupuncture and Radix Astragali aqua-acupuncture stimuli have long been used to cure human diseases. However, the exact physiological and biochemical mechanisms involved remain undiscovered. Thus, many attempts have been made to show the scientific mechanisms involved. The effects of acupuncture and Radix Astragali aqua-acupuncture, which was known to date, as follow; effective circulation of body blood system and proliferation of leucocytes. Methods : In this study, we have applied acupuncture and Radix Astragali aqua-acupuncture stimuli to mouse on Sinsuhyul, a stimulative point of oriental medicine, to see effects on the expression of cytokine $IL-1{\beta}$. Mice were treated with lipopolysaccharide(LPS) for inflammation induction and then reverse transcriptase-polymerase chain reaction (RT-PCR) using each primer set were performed to trace the amounts of mRNA. Results : 1. $IL-1{\beta}$ was not expressed in LPS-nontreated mice at 15 to 60 min after acupuncture-stimuli. However, expression occurred after 3hrs. 2. $IL-1{\beta}$ was specifically expressed in LPS-treated mice at 30 min after acupuncture-stimuli. 3. $IL-1{\beta}$ was expressed in LPS-nontreated mice at 30 min after Radix Astragali aqua-acupuncture stimuli, however, not expressed at 60, 180 min. 4. $IL-1{\beta}$ was gradually expressed in LPS-treated mice at 15 to 180 min after Radix Astragali aqua-acupuncture stimuli. Conclusions : $IL-1{\beta}$ in LPS-treated mice was more effective than that of LPS-nontreated mice. We are now in the process of elucidating the immunological action mechanism of acupuncture and Radix Astragali aqua-acupuncture stimuli. And cytokine $IL-1{\beta}$ can be used not only as a basis of the effects of acupuncture and Radix Astragali aqua-acupuncture but also as a diagnosis guide through the immunological actions of those.

This study was performed to investigate concept, systoms, causes of disease, pathogenic mechanisms, therapies and precriptions about senile constipation through the successive medical literature, recent chinese medical literature and chinese medical joumals. Senile constipation seems to be applicable to dryness syndrom and constipation of insufficiency type, have something to do with kidney(the most), lung, spleen and large intestine. The most principal cause of disease is yin-fluid, the rest deficiency of qi, insufficiency of yang, stagnation of qi and retention of fever etc. There are enriching the blood and moistening dryness in principal therapy, the rest are invigorating qi and loosing the bowel, warming and invigorating the spleen and kidney, regulating the flow of qi and promoting the stagnancy of qi and expelling the pathogenic heat etc. In prescriptions there are Yunjangtang, Jengaektang, Hwanggitang, Jechunjeon, Yukmatang and Majainhwan as the causes of disease, meanwhile are Yungjang-tang, Jechunjeon and Majainhwan in the vulgaris prescriptions. And in medical herbs there are nourishing yin medicines as Rhizoma rehmanniac, Radix ophiopogonis and Radix scrophulariae etc., invigorating qi medicines as Radix astragali, Radix codonopsitis and Radix polygoni multiflori etc, invigorating yang medicines as Caulis cistanchis and Semen psoraleae etc., promoting qi circulating medicines as Radix saussurea, Lignum aquilariae and Radix linderae etc., and reducing fever and therapeutic method to keep the adverse qi flowing downward medicines as Semen cannabis, Rhizoma rhei, Fructus immaturus ponciri, and Cortex magnoliae etc.. Meantime Rhizoma rehmanniae, Radix ophiopogonis, Caulis cistanchis, Radix angelicae gigantis, Semen cannabis, Semen biotae, Semen pruni japonicae and Semen persicae in principal herb-medicines. In clinical reports the process of disease was between 10 to 20 years, the evacuation cycle between 4 to 7 days, generally possessed chronic diseases as hypertension, diabetes, arteriosclerosis and cerebro- vascular disorders etc. and the efficiency rate was more than 90%. The senile constipation is occured in succession or promoted by chronic diseases as obesity, hypertension, diabetes, arteriosclerosis. hrperlipemia, cerebro- vascular disorders etc., so diet-regulating, adequate exercise, proper evacuation-habit and psychologic rest etc. are important more than medicine-treatments.

In tins paper, a new DA(Distributed Arithmetic) tilter implementation technique has been proposed. Contrary to vertical directional calculation of input sample bit format in the conventional DA implementation technique, proposed implementation technique utilizes horizontal directional calculation of input sample bit format. Since proposed technique calculates in horizontal direction, it does not need ROM and utilizes the Modified Booth algorithm. Furthermore proposed technique can be applied to implement the variable coefficients filters in addition to the fixed coefficients filters. Using conventional and proposed techniques, a 20 tap filter is implemented by Verilog-HDL coding. Through Synopsis synthesis tool, it has been shown that 41.6% area reduction can be achieved.
