The pharmacological mechanisms of most Oriental medicines have not been clearly defined in spite of their effective use in treating many diseases throughout the world. Many Oriental medicines have been used against various allergic diseases for generations, and still occupy an important place in traditional medicine in far eastern countries including Korea. It is also still unclear how Oriental drugs prevent allergic disease in vivo or in vitro models. Some Korean folk medicine inhibited the mast cell-mediated allergic reaction. This review summarizes the effective folk medicine in experimental effect on systemic or local anaphylaxis reaction. Potential anti-anaphylactic folk medicines include: Poncirus trifoliata; Siegesbeckia glabrescence; Solanum lyratum; Aquilaria agallocha; Ulmi radicis; Polygonum tinctorium; Hwanglyun-Haedok-Tang; Rehmannia glutinosa; Kum-Hwag-San; Syzygium aromaticm; Spirulina platensis; Sosiho-Tang; Sinomenium acutum; Schizonepta tenuifolia; Shini-San; Magnoliae flos; Sochungryong-Tang; Oryza sativa; Cryptotympana atrata; Salviae radix; Rosa davurica; Asiasari radix; Chung-Dae-San; Cichorium intybus; Perilla frutescens; Vitex rotundifolia; Terminalia chebula; Siberian Ginseng; Solanum melongena; Gahmi-Shini-San; Alpinia oxyphylla; Acanthopanax senticosus root; Prunella vulgaris; Allergina; Ixeris dentate; Acanthopanax senticosus stem; Tongkyutang; Salvia plebeia; Rubus coreanus; Sinpo- Tang; Dodutang; Forsythia fructus; Xanthii fructus; and Purple bamboo slat. Ensuring the effects and understanding the mechanisms of action for these Oriental medicines can permit drug development and laying of the ground-work for evaluating potential synergistic effects by addition and subtraction of prescriptions.

Decoctions of two Korean indigenous crude drugs. Radix Jingyu(the dried root of Aconitum pseudo-laeve Nakai var. erectum Nakai form. Genuinum Nakai) and Fructus ponciri (the transversely sliced and dried unripe fruit of Poncirus trifoliata Rafinesque), are being utilized by the inhabitants in certain parts of southeastern district of Korea with an empirical belief that these serve as effective insecticides for cattle ticks. Of the two species of cattle ticks so far identified in Korea, Boophilus microplus and Haemaphysalis bispinosum, the former was employed in this experiment as the species occupies nearly 99 percent of the tick population. The results of the experiments herein reported seen to indicate that although the killing power of aqueous extracts of the drugs is minimal, the repellent effect against the ticks, especially of Radix Jingyu, is excellent. It may be of interest to note that the aqueous extract of Radix Jingyu has not proved to be inferior to any of the most effective cattle repellents commercially available. Further studies on these Korean indigenous crude drugs as cattle tick repellents are indicated to find whether active ingredients can be extracted in a hope to materialize an extensive application of these drugs in the field.

Objectives : To identify the active ingredient of Poncirus Trifoliata Immaturus and to explore the mechanism expected to potentially act on dermatitis accompanied by pruritus. Methods : We conducted the network pharmacological analysis. We selected effective ingredients among the active compounds of Poinciri Fructus Immaturus. We found the target protein of the selected active ingredient, disease(dermatitis accompanied by pruritus) and fexofenadine. Then we established the network between the proteins which Poinciri Fructus Immaturus and fexofenadine intersected with disease respectively, and the coregene was also extracted. After that, the active pathways in the human body involving the groups and coregenes were searched. Results : Total of 7 active ingredients were selected, and 202 target proteins were collected. There were 756 proteins related to inflammatory skin disease accompanied by pruritus, and 75 proteins were related to fexofenadine. 42 proteins crossed by Poinciri Fructus Immaturus with a disease, and 31 proteins crossed by fexofenadine with a disease. 12 proteins were found as a coregene from the proteins that cross Poinciri Fructus Immaturus and disease. Coregenes are involved in 'Nitric-oxide synthase regulator activity', 'Epidermal growth factor receptor signaling pathway'. 2 groups that extracted are invloved in 'Fc receptor signaling pathway', 'Central carbon metabolism in cancer', 'Phosphatidylinositol 3-kinase complex, class IB', and 'omega-hydroxylase P450 pathway'. Conclusion : It is expected that Poinciri Fructus Immaturus will be able to show direct or indirect anti-pruritus and anti-inflammatory effects on skin inflammation accompanied by pruritus in the future. And it is also expected to have a synergy effect with fexofenadine on skin disease.

Ponciri Fructus (PF), the immature fruit of Poncirus trifoliata, has been used for treatment of constipation in Korean traditional medicine. It has been reported that PF has a prokinetic effect on gastrointestinal tract, but little is known about the effect on colonic contraction. The aim of this study was to investigate the effect of PF on spontaneous contractions of proximal and distal colon in rats. The aqueous extract of PF was centrifuged and filtered and its supernatant was used for in vitro motility study. The removed colon from rats was divided into proximal and distal segments. Each segment was mounted in a 10 ml organ bath and measured the change of the spontaneous contraction with increasing dose (1, 5, 10, 50, 100, 500, $1000{\mu}g/ml$) of PF extract administration. Also the effect of PF on the spontaneous contraction was measured under treatment of atropine, acetylcholine (Ach), and tetrodotoxin (TTX). PF increased the spontaneous phasic contraction of distal colon dose dependently, but there was no change in proximal colon. The contractile response induced by PF in distal colon was lower than that of Ach and was partially blocked by atropine ($10^{-6}M$). TTX increased the spontaneous contraction and it was reinforced with Ach addition. But the extract of PF had no or little contractile effect of TTX in colon. PF increased spontaneous contractions selectively in distal colon. The prokinetic effect of PF may be due to enhancement of cholinergic related excitatory neural system.

Objectives: Poncirus trifoliata Rafinesque has been known to have anti-allergic effects in skin diseases. However, anti-atopic dermatitis effects of P. trifoliata Rafinesque have not been studied yet in skin diseases. The present study evaluated the anti-atopic dermatitis effects of P. trifoliata Rafinesque (PTR) using external treatments on AD. Methods: AD lesions were induced by the repeated application of 2, 4-Dinitrochlorobenzene (DNCB) on the shaved back of BALB/c mice. $100{\mu}{\ell}$ of PTR extracts was applied to the AD lesions for 11 days. Histological assessments, mast cells count and serum levels of IgE were analyzed. The anti-pruritic effects of PTR were examined by the change of scratching frequency and nerve growth factor (NGF) expression. In addition, the anti-inflammatory effects of PTR were examined by the expressions of Th2/Th1 cytokines and pro-inflammatory in dorsal skin. Results: Histopathological findings showed that topical application of PTR decreased the thickness of dermal and epidermal skin compared with the DNCB group. PTR also notably decreased the mast cells count and serum IgE. The scratching behavior of mice and expression of NGF were significantly reduced. In addition, PTR group significantly suppressed the IL-4, IL-6, IFN-${\gamma}$ and TNF-${\alpha}$ cytokines compared to the DNCB group. Conclusions: These results indicated that P. trifoliata Rafinesque possess anti-pruritus and anti-atopic dermatitis properties. Therefore, P. trifoliata Rafinesque might be used for treatment of pruritus and atopic dermatitis.

Objectives : The purpose of this study was to examine the effects of herbal medicines on pacemaker potentials of large intestinal interstitial Cells of Cajal (ICC) in mice. Methods : We made the ICC culture in large intestine in mice and used the electrophysiological method to record pacemaker potentials. Also we used MTT assay to check cell viability and examined the ICC protein expression by western blot. Results : 1.Glycyrrhiza uralensis Fischer (GF) (50-150 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC₅₀ is 58.95 ㎍/ml. Angelica gigas (AG) (50-200 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC₅₀ is 77.22 ㎍/ml. Poncirus fructus (PF) (10-100 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC₅₀ is 13.39 ㎍/ml. Citrus unshiu S. Marcov. (CU) (10-500 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC₅₀ is 139.80 ㎍/ml. Gardenia jasminoides J. Ellis (GJ) (100-500 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC₅₀ is 78.70 ㎍/ml. Coptis chinensis (CC) (100-1000 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC₅₀ is 138.10 ㎍/ml. Scutellaria baicalensis (SB) (10-100 ㎍/ml) had no effects on pacemaker potentials and decreased frequency with concentration-dependent manners. IC₅₀ is 18.34 ㎍/ml. Atractylodes macrocephala koidzumi (AM) (10-100 ㎍/ml) induced pacemaker hyperpolarizations and decreased frequency with concentration-dependent manners. IC₅₀ is 18.54 ㎍/ml. 2. PF, SB and AM had no effects on cell death in large ICC. 3. PF increased the ANO1 and c-kit protein expression and SB and AM increased the c-kit protein expression in large ICC. Conclusions : These results suggest that PF, SB, and AM are likely to be the optimal combination of herbal medicines that can be used to treat diseases such as gastrointestinal motility disorders such as irritable bowel syndrome.

Overproduction of peroxynitrite ($ONOO^-$) causes a variety of disease such as atherosclerosis, hypercholesterolemia, diabetes mellitus or obesity. Peroxynitrite scavenging activities and HPLC analysis on the five Oriental medicinal drugs belonging to the genus Citrus, Aurantium or Poncirus (Rutaceae family) and HPLC analysis were taken to evaluate flavanone glycosides with peroxynitrite scavenging activity. The $IC_{50}s$ of the five crude drugs were shown as follows: Aurantii nobilis Pericarpium (Jinpi, 18.3 ${\mu}g$/ml), Citrii unshiu Pericarpium (Chungpi, 7.50${\mu}g$/ml), Citrii unshiu Semen (Gyulhaek, >50.0${\mu}g$/ml), Aurantii Fructus (Jigak, 18.3${\mu}g$/ml), and Poncirii Fructus (Jisil, >50.0${\mu}g$/ml) where Korean crude drug's names are noted in the parenthesis. Peroxynitrite scavenging effect of flavanones or their glycosides usually contained in Citrus species were observed as follows: hesperetin (1.89 ${\mu}g$/ml), naringenin (7.77 ${\mu}g$/ml), hesperidin (8.44 ${\mu}g$/ml), poncirin (>50.0 ${\mu}g$/ml)and ponciretin(>50.0 ${\mu}g$/ml). The activities of naringin and poncirin with ${\alpha}$-L-rhamnopyranosyl($1{\rightarrow}2$)-${\beta}$-D-glucopyranosyl moiety were weak. HPLC analytical data revealed that Jinpi (the peels of mature fruits of Citrus unshiu) and Chungpi (the peels of immature fruits of C. unshiu) had high quantities of hesperidin as the value of 142.1${\pm}$0.21 and 104.51${\pm}$1.10 mg/g dried weight, respectively. Poncirin was clearly detected in only Jisil and naringenin and naringin were not observed on the HPLC chromatogram of the five crude drugs.

Objectives : To determine the background against which Zhishi has been applied to treat Pi pattern, through examination of changes in Pi pattern treatments in a historical context. Methods : The properties and nature of Zhishi as written in multiple bencao texts were analyzed. In addition, understanding of the Pi pattern, the changes in its treatment were examined diachronically based on opinions of Zhang Zhongjing, Zhugong, and Li Dongyuan. Examples of Zhishi application in Pi pattern treating formulas were collected and their mechanisms analyzed. Results : Zhishi is strongly effective in relieving accumulation and stagnation, due to its properties of dispersing and lowering. The early view of contrasting Pi with Jiexiong shifted to viewing the Pi pattern as an inner damage, from the perspective of rising and lowering of the Qi mechanism based on the Spleen and Stomach. As a result, Zhishi became a key ingredient in the treatment of the Pi pattern. Conclusions : As the perspective of seeing Pi as one end of the Yin-Yang coupling with Jiexiong from the Shanghanlun shifted to seeing it as a problem of Qi mechanism of the Spleen and Stomach, Zhishi became a key ingredient in the formulas to treat Pi pattern. The complexity of Zhishi's direction made it appropriate to treat the changed Pi pattern.
