Broussonetia kazinoki twig extract (BKT) is recognized for its antioxidant and anti-cancer effects and natural whitening properties. So, it is used as a raw material for cosmetics. B. kazinoki twig is also an edible raw material. B. kazinoki has been used in Asia for paper production and oriental medicine, has anti-diabetic effects, and contains various flavonoids and alkaloids. In this study, to evaluate the efficacy of BKT on allergic skin inflammatory responses, we investigated its effects on factors related to skin inflammation in HaCaT keratinocytes and allergic responses in RBL-2H3 cells. There was no cytotoxicity of the 70% ethanol extract against HaCaT and RBL-2H3 cells. In HaCaT cells, stimulation with tumor necrosis factor-alpha (TNF-𝛼) and interferon-gamma (IFN-𝛾) increased the production of several chemokines, including thymus and activation-regulated chemokine (TARC), macrophage-derived chemokine (MDC), and regulated on activation, normal T cell expressed and secreted (RANTES). However, it was observed that this elevation was notably mitigated in a concentration-dependent manner upon treatment with BKT. Furthermore, BKT treatment demonstrated a significant reduction of 𝛽-hexosaminidase and inflammatory cytokines TNF-𝛼 and IL-4 in IgE-sensitized RBL-2H3 cells. Thus, it is expected that BKT can be used as a natural cosmetic and food ingredient that effectively suppresses allergic inflammatory reactions.

We report a 23-year-old woman with adult Sandhoff disease, who presented with motor neuron disease phenotype. The patient had experienced progressive motor weakness in four extremities since 1 year prior to admission. Electrophysiological study revealed wide-spread denervation potentials, and the assay of total hexosaminidase involving A and B activities showed decreased levels of these activities, which was consistent with Sandoff disease. This is the first Korean case of adult Sanhoff disease presented as a motor neuron disease phenotype.

Methods: Clinical features, laboratory and plasma lysosom enzyme activity by 4 MU-Fluorometric assay was studied from 2014-2015 at the Northern referral center of Pediatrics - National Children's Hospital. Results: 16 cases (7 girls and 9 boys) were diagnosed with I-cell bases on clinical symptoms and enzyme activities studies. Diagnosis age was $5.93{\pm}4.28$ years, onset age was recognised from birth to 4 years (median 1.25) with the feature of joint stiffness and bone deformation. All cases presented with the feature of joint stiffness, chest deformation and kyphoscoliosis; Fifteen cases (93.7%) had coarse facial features.

To evaluate the antithrombotic and antiallergic properties of rhaponticin extracted from Rhei Rhizoma, the in vitro and ex vivo inhibitory activities of rhaponticin and its metabolite, rhapontigenin, were measured. These compounds inhibited in vitro ADP- and collagen-induced platelet aggregation. Rhapontigenin was more potent, with $IC_{50}$ values of 4 and $70{\;}{\mu}g/ml$, respectively. In ex vivo ADP- and collagen-induced rat platelet aggregation, these compounds also exhibited a potent inhibitory effect. The antiplatelet aggregation effects of rhaponticin and rhapontigenin were more potent than those of aspirin. Rhapontigenin showed significant protection from death due to pulmonary thrombosis in mice. Rhapontigenin also showed the strongest inhibitory activity against $\beta-hexosaminidase$ release induced by DNP-BSA. These compounds inhibited PCA reaction in mice. Rhapontigenin intraperitoneally administered showed the strongest inhibitory activity and significantly inhibited PCA at doses of 25 and 50 mg/kg, with inhibitory activities of 48 and 85%, respectively. The inhibitory activity of orally administered rhaponticin was stronger than that of intraperitoneally administered rhaponticin. These results suggest that rhaponticin, in the rhizome of Rhei Rhizoma, is a prodrug that has extensive antiallergic and antithrombotic properties.

Oregonin is known as a representative active substance of plants of the Alnus species. In this study, we will show the results of establishing a method for extracting trace amounts of useful substances in plants. Additionally, a variety of physiological activity studies were conducted with extracts containing high content of useful substances. In this study, anti-oxidant, anti-inflammatory and anti-allergic activities of supercritical fluid residue 60% EtOH extracts of Alnus sibirica (ASCFR) were investigated in vitro. To explore anti-oxidant and anti-inflammatory characteristics of supercritical extract, DPPH radical scavenging, and ABTS radical scavenging activity, inhibition of nitric oxide production in LPS-stimulated RAW 264.7 cells and ${\beta}$-hexosaminidase release in IgE-stimulated RBL-2H3 cells were examined, respectively. Results showed a concentration-dependent increase in DPPH and ABTS radical scavenging activity. Cells stimulated with LPS produced more nitric oxide than normal control cells. However, cells treated with supercritical fluid residue 60% EtOH extract decreased production in a concentration-dependent manner. In anti-allergic activity studies, ASCFR showed concentration-dependentanti-allergic activity. Based on results and strong antioxidant activity, ASCFR has potential as basic research materials for development of therapeutic supplements-based medicines or functional cosmetics related to chronic inflammatory skin immunity diseases.

비만세포의 한 종류인 rat basophilic leukemia (RBL-2H3) 세포를 이용하여 교계사물탕-가감의 항알레르기 효과를 확인하고자 하였다. Phorbol 12-myristate 13-acetate (PMA)와 calcium ionophore A23187을 이용하여 RBL-2H3 세포를 자극한 후 세포의 탈과립 정도를 $\beta$-hexosaminidase assay로 확인한 결과, 전 처리한 교계사물탕-가감의 농도 의존적으로 탈과립을 억제하였다. Pro-inflammatory cytokines인 tumor necrosis factor (TNF)-alpha와 interleukin(IL)-4의 분비량을 enzyme-linked immunosorbent assay (ELISA)로 확인한 결과 교계사물탕-가감의 농도 의존적으로 감소하였으며, 이들 cytokines와 염증 반응에 주요한 인자인 cyclooxygenase (COX)-2 의 mRNA 발현 정도 역시 교계사물탕-가감에 의해 감소함을 확인할 수 있었다. 이러한 실험 결과로 보아 교계사물탕-가감은 알레르기 관련 질환의 치료에 응용될 수 있을 것으로 사료된다.

Objective: Previously, the methanol extracts of the semen of Xanthium strumsrium could involved anti-inflammatory effects in lipopolysaccharide (LPS)-stimulated Raw 264,7 cells, We evaluated the anti-allergic effects of X. strumarium on rat basophilic leukemia (RBL-2H3) cells, Methodes : To investigate the effect of X. strumarium on the phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187-induced RBL-2H3 cells. The effects of X. strumarium on the degranulation and the pro-inflammatory cytokines secretion and expression from RBL-2H3 cells were evaluated with $\beta$-hexosaminidase assay, ELISA, and RT-PCR analysis, In addition, we examined the effects of X. strumarium on nuclear factor (NF)-${\kappa}B$ activation and $I{\kappa}B-\alpha$ degradation using Western blot analysis. Results : X. strumarium inhibited degranulation and secretions and expressions of pro-inflammatory cytokines, such as tumor necrosis factor-alpha ($TNF-\alpha$), interleukin (IL)-4 and cyclooxygenase (COX)-2, on stimulated RBL-2H3 cells, however, X. strumarium not affect cell viability. In stimulated RBL-2H3 cells, the protein expression level of nuclear factor-kappa B (NF-${\kappa}B$) was decreased in the nucleus by X. strumarium. In addition, X. strumarium suppressed the degradation of inhibitory protein $I{\kappa}B-{\alpha}$ protein in RBL-2H3 cells. Conclusion : These results suggest that X. strumarium inhibits the degranulation and secretion of pro-inflammatory cytokines through blockade of NF-${\kappa}B$ activation and I $I{\kappa}B-{\alpha}$ degradation.

In previous report, Seungmagalgeun-tang (SGT) could exert its anti-inflammatory actions in the BV-2 microglial cells. However, study on the anti-inflammatory effect of SGT in mast cells has not been identified. Therefore, we examined on the anti-inflammatory effect of SGT on the phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187-induced rat basophilic leukemia (RBL-2H3) cells. SGT inhibited the release of ${\beta}$-hexosaminidase and secretion and expression of pro-inflammatory cytokines such as tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-4 on RBL-2H3 cells, without affecting cell viability. The protein expression level of nuclear factor (NF)-${\kappa}B$ (p65) was decreased in the nucleus by SGT. In addition, SGT suppressed the degradation of inhibitory protein $I{\kappa}B-{\alpha}$ protein, the activation of p38 mitogen-activated protein kinase (MAPK), and the expressions of cyclooxygenase (COX)-2 mRNA and protein level in RBL-2H3 cells. These results suggest that SGT could be involved anti-allergic effect by control of NF-${\kappa}B$ (p65) translocation into the nucleus through inhibition of $I{\kappa}B-{\alpha}$ degradation and suppression of COX-2 expression.
