The purpose of this study was to investigate the possibility of herbal medicine complex extract (NI-01), which were prepared from 6 natural materials (Cinnamomum cassia Blume, Lonicerae Flos, Paeonia suffruticosa Andrews, Arctium lappa Linne, Schzandra chinesis Bailon, Elsholtzia ciliata Hylander), as a functional material for inhibition of atopic dermatitis. anti-oxidative activity was confirmed by measuring DPPH electron donating ability and ABTS+ radical scavenging ability. Cytotoxicity and NO inhibition were measured using RAW 264.7 cells to confirm anti-inflammatory efficacy. The test substance was orally administered to the pruritus-induced ICR mice to confirm the inhibition of pruritus. The bovine cornea opacity and permeability (BCOP) assay was performed to confirm safety for irritation. NI-01 showed high antioxidant activity in DPPH and ABTS+ methods. In the anti-inflammatory effect tests with RAW 264.7 cells, NO production was inhibited at NI-01 concentrations of 50 (14.9%) and 100 (4.2%) ㎍/mL, which indicated that the anti-inflammatory effect was increased in a concentration-dependent manner. NI-01 also showed anti-itching effect after inducing of itching by compound 48/80 in ICR mice. NI-01 was proved to be a non-irritant substance in BCOP assay. The results of this study suggested that the herbal medicine combined extract (NI-01) has high antioxidant, anti-inflammatory and anti-itching effects, and safety for irritation. Therefore, herbal medicine complex extract (NI-01) is thought to be highly applicable for the inhibitory ingredients of the atopic dermatitis.

Crotamiton is an anti-scabies drug, but it was recently found that crotamiton also suppresses non-scabietic itching in mice. However, the underlying mechanism is largely unclear. Therefore, aim of the study is to investigate mechanisms of the anti-pruritic effect of crotamiton for non-scabietic itching. Histamine and chloroquine are used as non-scabietic pruritogens. The effect of crotamiton was identified using fluorometric intracellular calcium assays in HEK293T cells and primary cultured dorsal root ganglion (DRG) neurons. Further in vivo effect was evaluated by scratching behavior tests. Crotamiton strongly inhibited histamine-induced calcium influx in HEK293T cells, expressing both histamine receptor 1 (H1R) and transient receptor potential vanilloid 1 (TRPV1), as a model of histamine-induced itching. Similarly, it also blocked chloroquine-induced calcium influx in HEK293T cells, expressing both Mas-related G-protein-coupled receptor A3 (MRGPRA3) and transient receptor potential A1 (TRPA1), as a model of histamine-independent itching. Furthermore, crotamiton also suppressed both histamine- and chloroquine-induced calcium influx in primary cultures of mouse DRG. Additionally, crotamiton strongly suppressed histamine- and chloroquine-induced scratching in mice. Overall, it was found that crotamiton has an anti-pruritic effect against non-scabietic itching by histamine and chloroquine. Therefore, crotamiton may be used as a general anti-pruritic agent, irrespective of the presence of scabies.

Sho-Seiryu-To is known to be effective against allergic diseases, but its effect on skin itching has not been reported. We observed the effect of Sho-Seiryu-To on three elderly patients who, desoite using an anti-allergic drug, has severe chronic skin itching with peripheral eosinophilia. All three patients decreased their peripheral eosinophilia and improved their skin condition within eight weeks. We conclude that Sho-Seiryu-To could be capable of treating elderly patients with chronic skin itching and peripheral eosinophilia.

Objective : This study describes a case of urticarial drug eruption assumed to be caused by non-steroidal anti- inflammatory drugs (NSAIDs) treated with oriental medicine and acupuncture. Methods : We studied the case of 20-years-old drug eruption patient. The patient complained of urticaria, angioedema, itching and burning sensation after taking NSAIDs. The indications for NSAIDs prescribed were common cold symptom and sore throat. For diagnosis, blood test and urinalysis were done. For treatment, acupuncture and herbal-medicine treatment were applied. Results : The patient of this report were examined for 13 days. The radiological finding was within normal limits. The WBC, neutrophil, lymphocyte and eosinophil level normalized during admission. After 3 days, itching and wheal reaction of whole body disappeared except facial symptom. The angioedema, itching and wheal reaction in the face was almost improved in the 4th day after discharge. Conclusions : We may expect that the oriental medical therapy improves the urticarial drug eruption caused by NSAIDs.

Objectives : 'Obtaining qi(deqi)' is a sensation experienced by a patient or an acupuncturist during acupuncture treatment, and it is considered to be an important factor in acupuncture treatment. However, previous studies reported conflicting results about the relationship between 'obtaining qi(deqi)' sensation and the effect of acupuncture treatment. Also, most of the previous studies investigating 'obtaining qi(deqi)' and the acupuncture effect, dealt with the analgesic effect of acupuncture. The objective of this study was to analyze the relation between the 'obtaining qi(deqi)' and the anti-itching effect of acupuncture treatment. Methods : Twenty one healthy subjects participated in this study. At the first visit, itch was induced to all subjects using intradermal injection of histamine on the lower arm. At the second visit, acupuncture treatment was applied using LI11 and 'obtaining qi(deqi)' was assessed. After acupuncture treatment, itch was induced again, and itch VAS and skin flare were assessed. Results: At the 6,8,10 minutes after histamine injection, the change of itch VAS between before and after acupuncture treatment was significant. Among 'obtaining qi(deqi)', subjects reported that 'dull ache', 'pricking', 'heavy' were most strong. Total score of 'obtaining qi(deqi)' sensation was not related to the change of itch VAS or skin flare. The 'electric shock' sensation is related to the change of itch VAS, and 'bruised' and 'heavy' sensations were related to the change of skin flare. Conclusions : Total 'obtaining qi(deqi)' is not related to the anti-itching effect of acupuncture, but several sensations showed relationship with the effect of acupuncture on itch severity and skin flare. Further researches based on various symptoms or acupuncture points, are needed.

Anticonvulsant hypersensitivity syndrome includes fever, skin eruptions, lymphadenopathy, hematologic abnormality and hepatitis, but its mechanism remains unknown. Anticonvulsants including phenytoin, carbamazepine can cause hypersensitivity reaction. We treated a patient who had severe itching sensation and insomnia: he had undergone an operation for cerebral hemorrhage and was administered anti-convulsant agents to prevent convulsions. We administered the anti-convulsant, Dangkwieumja(Dangguiyinzi). After the treatment, clinical symptoms caused by hypersensitivity were improved.

This study was conducted to evaluate the anti-inflammatory activity and clinical efficacy of a sample (A.C.C. extracts) obtained by distillation extraction of 14 herbal medicines including Phellodendron bark. To confirm this, the amount of nitric oxide (NO) produced by the cells in RAW 264.7 cells stimulated by lipopolysaccharide (LPS) and the changes in the production of inflammatory cytokines such as tumor necrosis factor (TNF)-${\alpha}$, interleukin(IL)-$1{\beta}$ and IL-6 were determined. The results showed that A.C.C. extracts strongly inhibited the production of NO and inflammatory cytokines increased by LPS without cytotoxicity. In addition, A.C.C. extracts showed strong bacterial reduction rates of 99.9% in Pseudomonas aeruginosa, Staphylococcus aureus, MRSA (Methicillin-resistant Staphylococcus aureus), Candida albicans and Streptococcus mutans. These findings indicate that A.C.C. extracts are effective ingredients with a strong antimicrobial effect together with an anti-inflammatory effect. In addition, when A.C.C. extracts were applied to infants and toddlers who were suffering from diaper rash, itching, and perspiration symptoms, symptoms of rash, atopy, rash, itching, and heat rash were improved. After the lapse of time, it was visually confirmed that it was considerably relaxed. These findings confirm that A.C.C. extracts comprise a clinically effective anti-inflammatory and anti-bacterial agent that alleviates symptoms such as diaper rash and fever and may therefore be an effective alternative to inflammatory diseases.

Purpose: The purpose of this study was to compare characteristics of two groups (pruritus and non pruritus group), in hemodialysis patients. Method: The degree of ichting in 130 patients treated at the D Medical Center Hemodialysis Unit was examined by itching severity & sites tool, itching observation tool and itching NRS tool. The data were collected from October 1 to 12, 2007 and analyzed by student t-test and Mann-Whitney test. Result: Sixty three patients (48.3%) of hemodialysis patients had pruritus. The severity and number rating scale score of pruritus in one day before hemodialysis was higher than during and after hemodialysis. The frequency of dialysis and usage of anti-histamine drug were significantly lower in nonpruritis group than in pruritus group (F=5.209, p=.022, F=6.549, p=.010). The other general characteristics, hemodialysis-related characteristics and laboratory data were not significantly different between the two groups. The depression score was significantly higher in pruritus than in nonpruritus group (t=-2.505, p=.017). But there were no significant differences in hostility and anxiety between the two groups. Conclusion: Residual renal function and depression were associated with pruritus in hemodialysis patients. Efforts for preservation of residual renal function and emotional support may decreased severity and frequency of pruritus in hemodialysis patients.

Objectives : Danguieumja is a traditional medicinal prescription to treat skin disease. It was commonly used for the treatment of itching, chronic urticaria and atopic dermatitis in Korea by the addition or omission of several herbs. This study investigated the anti-inflammatory potential of Gagam-Danguieumja (GDE) water extract. Methods : We examined the effects of GDE on the lipopolysaccharide (LPS)-induced production of nitric oxide (NO) in a murine macrophage cell line, RAW 264.7 cells. Results : GDE inhibited production of NO in a dose dependent manner and also decreased the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2). As a possible molecular mechanism of anti-inflammatory effect increased phosphorylation of mitogen-activating protein kinases (MAPK) by LPS were blocked by GDE treatment. Conclusions : These results suggest that GDE has an anti-inflammatory therapeutic potential through the inhibition of MAPK phosphorylation, thereby decreasing the expression of pro-inflammatory genes.

Owing to improvement of socioeconomic status during recent decades in Korea, incidence of hepatitis A has rapidly decreased, especially among children. However, this status has paradoxically caused a steady increase of adult patients with HAV infection, causing new medical issues associated with aggravated clinical symptoms. The present study reports an adult case of acute viral hepatitis type A treated with oriental medicine. The elevated biochemical findings(AST, ALT, gamma-GTP, bilirubin), physical symptoms (general weakness, nausea, right flank pain, itching sign), and serological makers (anti-HAV IgM and anti-HAV IgG) were normalized within four weeks. Also, sonographic examination showed a normal pattern on an enlarged liver image. This study informed us about the clinical capacity of oriental medicine for adult patients with acute viral hepatitis type A.
