Traditional medicines usually use combinational formula that are prepared by mixing different varieties of medicinal herbs and boiling them in water to yield a decoction. In recent years a modified method has been proposed and practiced wherein the individual herbs are boiled with water separately and later these extracts are mixed together for use. We attempted to evaluate their equivalence in terms of its polyphenol contents and DPPH radical scavenging activity. The polyphenol contents as well as the DPPH radical scavenging activities were very similar to each other.

The purpose of this study is to investigate the protective effects of 25 herbal formulas on acetaminophen (APAP) or D-galactosamine (D-GalN)-induced hepatotoxicity in primary rat hepatocytes. Cell viability was measured using by Cell Counting Kit-8. 15 kinds of herbal formulas significantly reversed the cell viabilities of D-GalN-treated rat hepatocytes compared with D-GalN alone (p<0.05). In particular, 9 herbal formulas (Bangpungtongseong-san, Bojungikgi-tang, Galgeun-tang, Gumiganghwal-tang, Guibi-tang, Sagunja-tang, Samsoeum, Pyeongwi-san and Yijin-tang) showed the potent protective effects. However, 8 herbal formula exerted weak protective effects and 2 herbal formula did not exert effects on hepatotoxicity by D-GalN. On APAP-induced hepatotoxicity, 7 kinds of herbal formulas increased the viabilities of hepatocytes compare with APAP alone (p<0.05). These results could be provide a valuable information for the future in vivo or clinical studies to predict the hepatoprotective effects of herbal formulas.

Objectives : The objective of present study was to investigate the vasorelaxant effects of 10 traditional Korean Herbal Prescriptions (KHP) on isolated rat thoracic aorta precontracted with potassium chloride (KCl). Methods : An electric extractor was used to extract KHP in distilled water for 3h. Rat aorta rings were isolated and were precontracted using KCl in organ chambers containing 10 ml Krebs Henseleit (KH) buffer. KHP extracts were added in increasing concentrations (10-1000 ㎍/㎖) to investigate vasorelaxant effects. The vasorelaxant responses induced by KHP were expressed as a percentage in response to contraction generated by KCl. Results : Among the 10 KHP, Gamisoyo-san, Galgeun-tang, Gyeji-tang, Gwakhyangjeonggi-san, Daeyoung-jeon, and Socheongryong-tang showed significant vasorelaxant effect at high concentration. In contrast, Gyejibokryeong-hwan constricted more the aorta rings precontracted by KCl. And Gumiganghwal-tang, Guibi-tang, Saengmaek-san showed no significant effect. Also, rat aorta rings treated with Gyejibokryeong-hwan or Gyeji-tang after pre-relaxation by amlodipine did not cause any significant change. Conclusion : Thus, these results provide the experimental evidence as useful herbal prescriptions for the treatment of hypertension and suggest guidelines in conjunction with other western drugs, including amlodipine.

The purpose of this study was to examine the anti allergic effect in vivo and in vitro, and to observe single and four weeks repeated toxicity in mice of Bangpung-galgeun-tang (BGT). We investigated anti DNP IgE-mediated passive cutaneous anaphylaxis in rodents and compound 48/80-induced active systemic anaphylatic shock in mice after oral administration with BGT of 0.4 g/kg and 0.8 g/kg for 8 days, and also examined MTT assay, ${\beta}-hexosaminidase$ activity, IL-4 and $TNF-{\alpha}$ from RBL-2H3 and $TNF-{\alpha}$ from Raw264.7 after pre-treatment with BGT of 0.25 mg/ml, 0.5 mg/ml, 1 mg/ml and 2 mg/ml. To ascertain safety and toxicity of BGT, we divided into single and four weeks repeated administration test. In single test, three groups were administrated different dosages and routes (2 g/kg/i.p., 4 g/kg/i.p. and 15 g/kg /p.o.) of BGT, and in four weeks repeated test, 0.8 g/kg BGT was administrated. Control groups were administrated with only saline according to on Korean Food and Drug Administration, respectively. We observed attentively motality, abnormal clinical sign, body weight change, organ weight, AST and ALT of mice after BGT administration. BGT inhibited passive cutaneous anaphylaxis and active systemic anaphylatic shock by oral administration. All the concentrations of BGT from 0.25 to 2 mg/ml didn't have an effect on cell viability and cytotoxicity. In RBL-2H3, ${\beta}-hexosaminidase$ release, IL-4 and $TNF-{\alpha}$, and in Raw264.7, $TNF-{\alpha}$ were significantly reduced by treated all concentrations of BGT. During toxicity experiment period, there was no difference in body weight change, organ weight, AST and ALT among different dose groups. Death were found 3 mice from day 2 to day 3 in single test i.p. group. (2 g/kg, 4 g/kg). Several individuals of single test i.p. group were observed that decreased locomotor activity, exophthalmos, bloodshot eyes, loss of eyesight and so on in early period after administration. But there was no difference in clinical signs among p.o. group. These results indicate that BGT have inhibition effects on allergy and suggest that no observable effect level of the test orally administration was considered to be more than 2 g/kg in mice under the conditions employed in this study.

Objectives: The purpose of this study was to establish experimental evidence for the antimicrobial effects of 51 herbal formulae commonly used in traditional Korean medical institutions. Methods: The antimicrobial activities of herbal formulae were screened using the disc diffusion method against 10 pathogenic microorganisms (Bacillus cereus, Staphylococcus aureus, Listeria monocytogenes, Vibrio parahaemolyticus, Escherichia coli DH5α, E. coli O157, Salmonella enteritidis, Yersinia enterocolitica, Shigella flexneri, and Helicobacter pylori). Of the 51 herbal formulae, 13 herbal formulae with antimicrobial activity were selected and their dose-dependency were confirmed. Results: Nine herbal formulae, including Gyeji-tang, Dangguisu-san, Saengmaek-san, Samul-tang, Ssanghwa-tang, Socheongryong-tang, Yukmijihwang-tang, Jakyakgamcho-tang, and Paljung-san, presented antibacterial activity against B. cereus. The effects of Saengmaek-san and Paljung-san was sustained for 48 hr. On L. monocytogenes, Dangguisu-san and Hyangsapyeongwi-san showed antimicrobial activity, but only Hyangsapyeongwi-san maintained the activity for 48 hr. Thirteen herbal formulae such as Galgeun-tang, Gyeji-tang, Dangguisu-san, Mahwang-tang, Banhasasim-tang, Saengmaek-san, Socheongryong-tang, Yukmijihwang-tang, Jakyakgamcho-tang, Cheonwangbosim-dan, Palmijihwang-tang, Paljung-san, and Hwanglyeonhaedok-tang showed antimicrobial activity against V. parahaemolyticus, and the activity was maintained for 48 hr. The 51 herbal formulae did not show any antimicrobial activity against seven strains such as E. coli DH5α, E. coli O157, S. aureus, S. enteritidis, Y. enterocolitica, S. flexneri, and H. pylori. Conclusions: Nine, two, and thirteen herbal formulae showed antimicrobial activities against B. cereus, L. monocytogenes, and V. parahaemolyticus in a dose-dependent manner, respectively. The results of antimicrobial activity of 51 herbal formulae against 10 microorganisms might be used as the basis for new application of herbal formulae.

Objectives: To compare the contents of heavy metals, residual pesticides and sulfur dioxide before/after a decoction. Methods: The heavy metal contents before/after a decoction were measured by Inductively Coupled Plasma Atomic Emission Spectrometer(ICP-AES) and mercury analyzer. In order to analyze pesticides in 5 samples we used simultaneous multi-residue analysis of pesticides by GC/ECD, which was followed by GC/MSD analysis to confirm the identity of the detected pesticide in each sample. In addition, the contents of sulfur dioxide($SO_2$) were performed by Monier-Williams distillation method. Results: 1. The mean values of heavy metal contents(mg/kg) for the samples were as follows: Galgeun-tang(before decoction-Pb; 0.793, Cd; 0.133, As; 0.016 and Hg; 0.005, after decoction-Pb; 0.033, Cd; 0.004, As; 0.002 and Hg; not detected), Gumiganghwal-tang(before decoction-Pb; 0.934, Cd; 0.197, As; 0.046 and Hg; 0.006, after decoction-Pb; 0.062, Cd; 0.007, As; 0.004 and Hg; 0.0001), Sosiho-tang(before decoction-Pb; 0.891, Cd; 0.134, As; 0.091 and Hg; 0.014, after decoction-Pb; 0.036, Cd; 0.002, As; 0.004 and Hg; not detected), Ojuck-san(before decoction-Pb; 0.907, Cd; 0.136, As; 0.084 and Hg; 0.007, after decoction-Pb; 0.074, Cd; 0.007, As; 0.011 and Hg; 0.0005) and Samsoeum(before decoction-Pb; 1.234, Cd; 0.154, As; 0.016 and Hg; 0.007, after decoction-Pb; 0.094, Cd; 0.006, As; 0.002 and Hg; 0.001). 2. Contents(mg/kg) of residual pesticides before/after a decoction in all samples were not detected. 3. Contents(mg/kg) of sulfur dioxide($SO_2$) before a decoction in Galgeun-tang, Gumiganghwal-tang, Sosiho-tang, Ojuck-san and Samsoeum exhibited 1.2, 3.4, 11.1, 12.0 and 5.7, respectively. However, contents of sulfur dioxide after a decoction in all samples were not detected. Conclusions: These results will be used to establish a criterion of heavy metals, residual pesticides and sulfur dioxide.

1. Backgrounds: There are a lack of comprehensive study on Taeeumin Exterior Heat syndrome diarrhea(表熱證泄瀉). Thus, The author examines the content of various literatures related to Tae-eumin Exterior Heat syndrome diarrhea. 2. Methods: Literature examination is used Lee, Je-ma's writings and Sasang Constitutional Medical doctor's writings. Syndrome examination is used Tae-eumin's study on Syndrome of DonguisusebowonGaboGu-bon("咸山沙村東醫壽世保元甲午舊本") and Donguisusebowon("東醫壽世保元") and treatises of the academic world. 3. Results: and Conclusions: 1) "Profuse sweating and reddish and difficult urination"(汗多而小便赤澁) is regard as Taeeumin Interior Febrile Disease(裏熱病). 2) There is no possibility of a misprint about Taeeumin Exterior Heat syndrome diarrhea. Taeeumin Exterior Heat syndrome diarrhea is engaged in both the Exterior and Interior(表裏俱病). 3) It is difficult to prescribe GalgeunHaegi-Tang(葛根解肌湯) instead of Galgeunnabokja-Tang(葛根蘿葍子湯). 4) Tae-eumin Exterior Heat syndrome diarrhea is formed in the early period and absorbed into Donguisusebowon ("東醫壽世保元") in the latter period. "Profuse sweating and reddish and difficult urination" is estimated to be added in the latter period.

Objectives: Most drug interactions are attributed to the inhibition or induction of the activity of cytochrome P450s (CYP450). Although the regulation of CYP450s by drugs has been widely reported, there have been few studies on influence of traditional herbal formulas on the drug-metabolizing enzymes. Because herbal formulas have been used traditionally to treat various diseases and because herb-drug interactions are crucial factors determining therapeutic efficacies, a systematic evaluation of the effects of herbal formulas is important. Methods: The effects of Galgeun-tang (GGT, gegen tang), Gumiganghwal-tang (GMGHT, jiuweiqianghuo tang), Insampaedok-san (ISPDS, renshenbaidu powder), Samsoeum (SSE, shensu drink), Socheongryong-tang (SCRT, xiaoqinglong-tang) and Sosiho-tang (SSHT, xiaochaihu tang) that are traditional herbal formulas used to treat common cold, on drug-metabolizing enzymes were evaluated through an in vitro CYP3A4, CYP2D6, CYP2C19 and CYP2E1 inhibition assay to assess its interaction potential with synthetic drugs. The inhibitory effects of herbal formulas were characterized with $IC_{50}$ values. Results: These six herbal formulas inhibited the activities of CYP3A4, 2C19, 2D6 and 2E1, in a concentration-dependent manner. Among the six herbal formulas, GGT critically inhibited CYP2C19, CYP2D6 and CYP2E1. GMGHT also inhibited CYP2D6 and CYP2E1 to a greater extent than the other CYP450 isozymes. Additionally, SSE and SSHT may change the effects of medicines that depend primarily on the CYP2C19 and CYP2E1 pathways. On the other hand, ISPDS and SCRT were not inhibited CYP3A4, CYP2C19, CYP2D6 and CYP2E1-mediated metabolism. Conclusions: These findings provide useful information regarding the safety and effectiveness of herbal formulas.
