Pueraiae Radix (PR), Pueratia Folium (PF) and Sorbus commixta (SC) mixture, namely GS-SP (PR (1)/PF (2)/SC (0.5): v/v/v) was developed as hangover-relieving elixir and its effects on alcoholic metabolism have been investigated. The enzymatic activity of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) of GS-SP was shown higher than those of single treatment with PR, PL, SC, and the positive control group (YM-808). The survival rate of mouse liver cell line NCTC clone 1469 in the presence of acetaldehyde was 30.6, 22.2, and 8.7% at the GS-SP dosage level of 50, 100, and 200 μg/mL respectively. Different concentrations of 50, 100 and 200 mg/kg of GS-SP showed efficient activity for ADH and ALDH than YM-808 in rat fed with 25% ethanol. The levels of blood alcohol and acetaldehyde after oral administration of 200 mg/kg of GS-SP showed efficient activity of 11.7% and 37% than those of YM-808. These results have been supported to the potential for GS-SP to serve as an excellent potential in providing hangover relief and liver protection.

We studied to compare hypoglycemic effect of GRA and MF in multiple low dose streptozotocin(STZ)-induced diabetic rats. 25 mg/kg of STZ in 100 mM citrate buffer(pH 4.5) was injected intraperitoneally for 5 consecutive days. SD rats were randomly divided into diabetic control and treatment groups. Treatment groups were administered with either 500mg/kg of GRA. 500mg/kg of MF. 250mg/kg of GRA＋250mg/kg of MF(GM 250)or 500mg/kg of GRA＋500mg/kg of MF(GM 500) for 3 weeks. (omitted)

Mulberry, Mori folium leaves (ML) and fruits (MF), Lycii fructus (LF), and Panax ginseng have been known to maintain normal blood sugar levels (BSL) in folk medicine. Here we investigated the effects of coated rice with these herb extract to diabetic patients. Alloxan-induced diabetes mellitus (DB) mice (80 mg/kg BW., i.v.) separated into 3 groups. One group received the extract in high dose (6.5 mg/kg B.W.), and another one group received in low dose (1.3 mg/kg B.W.) perorally for 30 days. (+) control received no extracts. (-) control received neither of them. BSL, volume of water consumed (VWC), body weights (BW) of each group were measured and compared. BSL in both of the extracts-received groups got close to normal levels on 4th week after starting the experiments. VWC also showed the same pattern. BSL in (+) control remained high through the experiment periods. BW in (+) control remained high, but those in the extracts-received groups recovered to normal levels. The clinical trials for both of healthy volunteers and DB patients, conducted in a University Hospital, also showed that the rice coated with the extracts could control the BSL. From these results, we suggest that the functional rice with herb extracts could be used as a new alimentotherapy for DB patients.

Objectives: The purpose of this study was to characterize the effect of the fraction of Korean mountain ginseng folium (FKG) on the learning and memory impairments induced by scopolamine. Methods: The memory ameliorating effect of FKG was investigated using a passive avoidance test, the Y-maze test, and the Morris water maze test in mice. Drug-induced amnesia was induced by treating animals with scopolamine(1mg/kg, i.p.). Results: FKG (2 or 4mg/kg, p.o.) administration significantly reversed scopolamine-induced cognitive impairments in mice by the passive avoidance test and the Y-maze test(P<0.05), and also improved escape latency in the Morris water maze test at 2 or 4mg/kg(P<0.05). Although FKG has little inhibitory activity for AChE (IC50 value; 1847 ${\mu}g/ml$) in an invitro study, phosphorylated extracellular signal-regulated kinase(pERK) was increased by the administration of FKG inhippocampus on immunohistochemistry. Conclusions: These results suggest that FKG may be a useful cognitive impairment treatment, and its beneficial effects are mediated, in part, via activation of ERK pathway.

Free amino acid (FAA) compositions in the central part (pith-xylem : P-X) and the outer part (phloem-cortex : P-C) of root were investigated for P ginseng (P.g), p. quinque-folium (P.q) an, B P nutoginsen (P.n) by an amino acid analyzer. Total free amlno acids content (TFAA) was highest in p.맥 and lowest in p.n. The TFAA of P-Xs were higher than those of P-Cs in these Panax species except p.n. The higher the TFAA in P-X, the higher the ratio of TFAA in P-X to that in P-C. Seven- teen free amino acids and ammonia were identified, and four unknown peaks appeared before the usual amino acids eluted. The total aspartic acid equivalent of these unknown peaks was corresponded to 77% of known TFAA in P-C of p.n, 17% in P. n, and 7% in p.q. The pattern of unknown peaks of p.g was different from p.q and similar to P.n. In all samples six major amino acids and ammonia accounted for 90~95% of TFAA. Arginine was comprised from 29% (P.n) to 43% (P.g) by amole as amino acid and from 50 to 71% by amole as nitrogen (N amole) in TFAA. Ammonia was the second abundant one by amole and the third by Npmole. Histidine was the second by Npmole. Praline was one of major FAA in p.q. Pattern similarity of FAA composition (excluding Arg and Am) by simple correlation was closer between P-C of p.g and P-X of p.q than between both P-Xs and quite different between the P-X of p.g and that of p.n. The pattern similarities of major FAA percent abundance excluding Arg and Am were significant only between P-X and P-C of the same species. Arginine content (amole) had positive correlation (r=0.859, p=0.05) with Arg/Am among species. Ammonia content was higher than arginine in p.n. Tryptophan content was greatest in p.n among species and higher than lysine only in p.n. The ratios of TFAA to N(W/W) were in the range of 3.89~4.14 for TFAA and 3.61~3.92 for TFAA plus ammonia.

Effects of twenty-three aqueous herbal extracts used in oriental medicines on heme oxygenase (HO)-1 expression were estimated in a mouse hippocampal cell line, HT22. HO-1 is one of the cytoprotective enzymes activated various stimuli, and Western blot analysis was used for evaluated HO-1 expression. Six aqueous extracts such as Rhei Rhizoma, Paeoniae Radix, Uncariae Ramulus et Uncus, Theae Folium, Prunellae Spica, and Coptidis Rhizoma significantly increased HO-1 expression in HT22 cells at the concentration of 300 ${\mu}$g/ml. In Addition, four aqueous extracts including Eucommiae Cortex, Moutan Cortex Radicis, Ginseng Radix Rubra, and Scutellariae Radix moderately increased HO-1 expression. These results would be usefulfor the isolation and identification of their neuroprotective principles.

본 연구에서는 예로부터 전해 내려오는 당뇨처방전에 사용되고 있는 문헌고찰을 토대로 6종의 약용식물(당귀, 백복령, 상백피, 상엽, 총목피 및 홍삼)의 항산화 및 항당뇨 활성을 비교 검토하고 이들의 상관관계를 검토하여 가장 효과적인 추출방법을 조사하였다. 당귀의 열수와 에탄올 추출물에서 각각 39.43와 37.75%로 다른 시료에 비하여 추출수율이 높았다. 폴리페놀 함량은 상백피 에탄올추출물에서 가장 높았고, 홍삼 초음파추출물에서 가장 낮았다. 플라보노이드 함량과 DPPH $RC_{50}$ 값은 상엽에탄올 추출물에서 가장 우수하였다. ${\alpha}$-Glucosidase저해활성은 상엽과 상백피 초음파추출물에서 높았고 추출방법 따른 저해율은 차이를 보였으나 세가지 추출물 모두 acarbose보다 높은 활성을 보였다. ${\alpha}$-Amylase저해활성은 상엽 에탄올추출물에서 가장 높은 저해활성을 보였고, 상백피와 백복령 에탄올추출물에서도 acarbose와 비슷한 결과를 보였다. 항산화 활성과 항당뇨 저해활성의 상관성은 에탄올 추출물과 초음파 추출물에서 유의적인 상관관계를 보였다. 에탄올 추출물에서 ${\alpha}$-glucosidase저해활성에 대한 폴리페놀 함량 또는 플라보노이드 함량과는 양의 상관관계($r^2$=0.792, 0.588)를 보였고, ${\alpha}$-amylase저해활성에 대한 플라보노이드 함량 또는 DPPH 소거능의 $RC_{50}$ 값에서도 음의 상관관계($r^2$=0.918, -0.594)를 나타내었다. 또한 ${\alpha}$-amylase 저해활성과 ${\alpha}$-glucosidase저해활성에서는 양의 상관관계($r^2$=0.746)를 보였다. 초음파 추출물에서는 ${\alpha}$-glucosidase저해활성에 대해 폴리페놀 함량과 플라보노이드 함량에서만 양의 상관관계($r^2$=0.763, 0.618)를 보였다. 항산화능에서의 상관관계를 살펴 본 결과 열수, 에탄올 및 초음파추출물에서 모두 폴리페놀 함량과 플라보노이드 함량, DPPH $RC_{50}$ 값과 유의적으로 높은 양의 상관관계가 있는 것으로 나타났다. 결론적으로 약용식물이 추출방법에 따른 항산화, 항당뇨 활성과 상관성에 차이를 보이고 있음을 알 수 있었다.
