  • Advances in the understanding of the Hippo signaling as a key regulatory pathway of proliferation and apoptosis have provided mechanical insights for controlling organ size and tumorigenicity. Recently, much attention has been directed to the regulation of LATS1/2 (large tumor suppressor) kinases that phosphorylate YAP/TAZ, a transcriptional co-activator in the Hippo pathway, and control the level and nuclear localization of YAP/TAZ. In our recent work, we showed that deubiquitinase YOD1 stabilizes ITCH, and facilitates ITCH-mediated LATS1/2 ubiquitination and degradation, resulting in increased YAP/TAZ level. Furthermore, we found that the YOD1-ITCH-LATS1/2-YAP/TAZ signaling axis is controlled by the differential expression of miR-21 in a cell-density-dependent manner. Using a transgenic mouse model, we showed that the inducible expression of YOD1 enhances the proliferation of hepatocytes and leads to hepatomegaly in a YAP/TAZ-activity-dependent manner. Moreover, a strong correlation was observed between YOD1 and YAP expression in liver cancer patients. Overall, our data suggest that YOD1 is a novel regulator of the Hippo pathway, and thereby a potential therapeutic target for liver cancer.

  • Atopic dermatitis is a common skin disease affecting up to 10% of children and approximately 2% of adults. Atopic dermatitis exhibits four major symptoms, including intense itching, dry skin, redness and exudation. The "itch-scratch-itch" cycle is one of the major features in atopic dermatitis. The pathophysiology and neurobiology of pruritus is unclear. Currently there are no single and universally effective pharmacological antipruritic drugs for treatment of atopic dermatitis. Thus, controlling of itch is a very important unmet need in patients suffering from atopic dermatitis. This article will update progress during the past 10 years of research in the field of pruritus of atopic dermatitis, focusing on aspects of pruritogens (including inflammatory lipids, histamine, serotonin, proteinases, proteinase-activating receptors, neurotransmitters, neuropeptides, and opioid peptides), antipruritic therapies, and emerging new targets. Based on recent progress, researchers expect to identify exciting possibilities for improved treatments and to develop new antipruritic drugs acting through novel targets, such as histamine H4 receptor, gastrin-releasing peptide receptor, MrgprA3, thromboxane A2 receptor and the putative SPC receptor.

  • International Hull Clauses(IHC(2003)) which have replaced the old system, Institute Time Clauses, Hull(ITCH), used more than 100 years in the shipping industry that did not fit the reality of the market and customs was announced in 01/11/2003 and was intended to supplement the existing issues to reflect the terms that had been used. IHC(2003) was composed of systematical and logical phrases to minimize the conflict which happened between the insured and the insurer after the incident. But IHC(2003) is being ignored by both the insured and the insurer in the shipping industry due to the differences in both positions. In addition, the studies about IHC(2003) in local academics are very low and many companies in the shipping industry are using both systems, IHC(2003) and ITCH so the usage of IHC(2003) is not so activated. Thus, this study will examines the main features and the compositions of IHC(2003) and compare IHC(2003) with ITCH(1983) in some provisions in both systems and then derive some similarities from the both systems and finally would suggest the necessity and validity of active use of IHC(2003).

  • A literature study was progressed for oriental medical treatment for atopic dermatitis. Atopic dermatitis is a chronic or chronically relapsing, pruritic dermatitis. In oriental medical treatment is classified into the treatment of inside(herb tea), treatment of outside(medicine for external application), treatment of inside & outside. The method of inside treatment is improving in health for the spleen and clearing wetness(健脾利濕), extinguishing wind and refreshing fever(消風淸熱), nourishing blood and making dryness gloss(養血潤燥). The method of outside treatment is refreshing fever and removing wetness(淸熱燥濕), counteracting the poison and getting rid of itch(解毒止痒), removing the boil and forming proud flesh(消腫生肌). The method of inside & outside is improving in health for the spleen and clearing wetness(健脾利濕), refreshing fever and getting rid of itch(淸熱止痒). refreshing blood and extinguishing wind(凉血祛風).

  • Objectives: This study was designed to assess traditional Korean medical therapy for urticaria and establish a clinical assessment guideline. Methods: Duration of symptoms, personal and family history of allergic diseases, serum IgE level, suspected causes and Provocation factors were investigated in 56 patients. Frequency of wheals, duration of wheals, number of wheals, itch severity and antihistamine counts on a 6-point (0-5) scale were assessed in 34 patients. The change of total scores and each criterion between baseline and follow up were analyzed using paired t-test (p<0.05). Results: 1. Acute urticaria within 6 weeks was $26.8\%$ and chronic urticaria over 6 weeks was $73.2\%$. The mean duration of symptoms was $19.2\pm38.8$ months. 2. $57.1\%$ of patients had a personal history of allergic diseases and $50\%$had a family history. $29.1\%$ had over 200 IU/mL serum IgE level. 3. The suspected causes were none $(39.3\%)$, foods $(32.1\%)$, drugs $(12.5\%)$, contact $(5.4\%)$ and maternity$(5.4\%)$. 4. The suspected provocation factors were foods $(41.1\%)$, none $(26.8\%)$, fatigue $(12.5\%)$, heat and sweating $(12.5\%)$, pressure $(10,7\%)$ and stress $(7.1\%)$. 5. The total scores between baseline and follow up of 34 patients were lowered from $15.38^{\circ}\;{\ae}3.75\;to\;8.82^{\circ}\;{\ae}5.21$, which was significant statistically (p=0.000). 6. Itch severity, frequency of wheals and number of wheals were the most significantly lowered of all criteria. Conclusions: Traditional Korean medical therapy was proven to be effective for urticaria, while itch severity, frequency of wheals and number of wheals should be assessed clinically with greater priority.

  • 본 연구는 여성암환우의 가발착용이 두피질환에 미치는 영향을 알아보고 향 후 암 환우들을 위한 가발 제작 시 필요한 기초자료를 제공하고자 실증 조사를 실시하였다. 그 결과 여성암 환우의 탈모용 가발 착용이 두피 가려움증에 미치는 영향은 가발착용 시 여러 가지 불편요소가 클수록 가려움을 유발하는 것으로 나타났으며 가발착용의 밀착성과 땀 분비, 심리적 위축성은 두피 가려움을 직접적으로 유발하지 않는 것으로 나타났다. 또, 여성암환우의 탈모용 가발 착용이 두피 트러블 유발에 미치는 영향에서도 가발의 탈착 시 불편 여부와 심리적 위축감이 높을 경우 두피 트러블을 유발시키는데 유의적인 영향을 미치는 반면 가발 탈착 시 밀착성과 땀 분비는 직접적인 연관이 없는 것으로 나타나 기각되었다. 이 같은 결과는 여성암 환우의 탈모용 가발 작용이 두피가려움과 트러블을 유발시킴에 있어 단순한 밀착여부와 땀 분비만으로 두피질환을 유발하지 않음을 시사한 것으로 볼 수 있다. 따라서 본 연구의 결과를 토대로 심적으로 고통 받는 여성 암 환우들을 위한 편리하고 우수한 가발 제작이 필요할 것으로 생각된다.

  • The antipruritic effect of DA-5018m a capsaicin derivative, was examined in mice. Male ICR mice were topically pretreated with Zostrix-HP (0.075% capsaicin cream), 0.1%, 0.3% DA-5018 cream or cream base (control) twice daily for 4 days. One hour after the last application, itch was induced either by compound 48/80 ($50{\mu}g$, s.c.) or leukotriene B4 (0.03 nmol, i.d.) injection into the rostral back of the animals, and the number of scratches made by the animals at the injection site was counted for 60 min post-injection. DA-5018 cream (both 0.1 and 0.3%) significantly inhibited compound 48/80-induced scratching when compared with the cream base control (p<0.01), which Zostrix-HP showed minimal inhibition of the scratching behavior. In leukotriene B4-induced itch model, Zostrix-HP and 0.3% DA-5018 cram significantly inhibited the scratching during the first 10-min period (p<0.01). The results suggest that DA-5018 cream can be used as an antipruritic agent and warrant clinical evaluation.

  • Dermatitis herpetiformis (DH) is a chronic disease of the skin marked by groups of watery, itch blisters. It is characterized by urticarial plaques and blisters on the elbows, buttocks, and knees, although other sites may also be involved. The ingestion of gluten (the proteins gliadin and prolamin contained in wheat, rye, oats, and barley) triggers an immune system reponse that deposits a substance, IgA (immonuglobin A), under the top layer of skin. IgA is present in affected as well as unaffected skin. DH is a hereditary autoimmune disease linked with celiac disease. Treatment for DH is twofold. (1) Remove the cause: gluten. (2) Suppress the skin response with drugs such as Dapsone or some other sulphones. The latter is the most common treatment used as it is rapidly relieves the itch. However there are some side effects associated with these medications and they need to be taken under medical monitoring with blood tests to detect side effects. Recently, we experienced a DH and that was successfully treated by the herbal medication and external therapy. The medications taken by the patient were yongdamsagantanggami and external therapy were gosam and gumunhwa. So we report this case with a bief review of the oriental medical and medical literatures.
