  • Objectives: Notopterygium incisum(N. incisum) and Saposhnikovia divaricata(S. divaricata) have been clinically used in traditional oriental medicine for treatment of inflammatory diseases. Also, a herbal mixture prepared with N. incisum and S. divaricata has been strongly linked to the anti-inflammatory effect. In this study, we evaluate the synergistic anti-inflammatory effect of N. incisum and S. divaricata. Methods: For evaluating the anti-inflammatory activity of a herbal mixture of N. incisum and S. divaricata in vivo, we measured the changed ear thickness in 12-O-tetradecanoyl-phorbol-13-acetate(TPA)-induced mouse ear edema model after topical application of herbal mixture. In addition, the levels of markers for inflammation, such as tumore necrosis factor (TNF)-${\alpha}$, interleukin (IL)-1${\beta}$, and nitric oxide(NO), were determined by ELISA assay in lipopolysaccharide-stimulated Raw 264.7 cells. Results: We reported that water extracts of N. incisum and S. divaricata combination significantly inhibited the mouse ear edema induced by TPA. Moreover, the water extracts of N. incisum and S. divaricata combination exhibited synergistic effects in down-regulating IL-1${\beta}$ level, but not TNF-${\alpha}$ and NO. Conclusions: These results suggest that combined treatment of N. incisum and S. divaricata, based on seven methods in prescription compatibility, has a synergistic effect in down-regulating inflammatory response both in vivo and in vitro models. Especially, it seems that IL-1${\beta}$ is a one of main target of the mixture of N. incisum and S. divaricata on anti-inflammatory activity.

  • The Transverse rectus abdominis musculocutaneous (TRAM) flap has been commonly used for autologous breast reconstruction. Despite these clinical usefulness, the TRAM flap is prone to partial flap or fat necrosis in especially pedicled flap. To improve flap survival, the surgical delay procedures and pharmacological treatments have been developed. In many studies for the pharmacological treatment, Lipo-$PGE_1$ has demonstrated a marked ability to improve flap survival and it's effect has been proved similar to surgical delay procedure. The purpose of this study is to determine the most effective route of Lipo-$PGE_1$ administration as a pharmacological treatment in TRAM flap of the rat. Fifty male Sprague-Dawley rats weighing 300-350 gm were divided into five groups, One week before flap elevation, Lipo-$PGE_1$($2{\mu}g/kg$) was injected three times in a week and than the left inferior epigastric vessel based TRAM flap ($5.0{\times}3.0cm$) elevated; group I: no procedure before flap elevation; group II: intraperitoneal injection; group III: intravenous injection; group IV: subcutaneous injection; group V: topical application. A flap was assessed at postoperative 7 days by comparison of flap survival rate, vessel counts(H-E stain), and vascular endothelial growth factor(VEGF) protein expressed by Western blot. The results demonstrated that the mean percentages of the flap survival area in group III were significantly higher than that of any other group(p<0.05). The vessel counts of all experimental groups were statistically higher than that of control group(p<0.05). Only in group III, the VEGF protein expression was increased significantly than control group and there are no difference in other experimental groups. In conclusion, the intravenous administration of the Lipo-$PGE_1$ is the most effective on flap survival, and the VEGF induced by Lipo-$PGE_1$ has some positive effects on new vessel formation and flap survival.

  • Steel industry which has been accomplishes the base of our country economy, automobile and electronic industry are taking charge of the role, whose electroplating is important. Large amount of wastewater and various metal salts, including hazardous materials was generated from the electroplating pre-treatment, plating, washing and post-plating. Currently, the general wastewater follows in the environmental law and neutralization after controlling, sludge where the various metal is mixed reclaims below multiple regulative and trust it is controlling. The sludge which includes the gas price metal reclaims in the field and trust it controls. a reclamation price of land it is insufficient but and the control expense holds plentifully and it loses the gas price metal which is valuable. Consequently, The research regarding to recover a gas price metal actively from this waste water, it is advanced. A new method to recover valuable metals from electroplating wastewater synthesis of metal sulfides using topical methods utilizing iron oxidizing bacteria, reagent of sulfides and solvent extraction using an organic solvent, such as the development of the law to recover these metals and metal sulfides of wastewater using selective recovery have been studied. By using these wastewater treatment method under frequency above 95%, it has been obtained the valuable metal from the wastewater, where the metal ion of Fe, Cu, Zn and Ni complexes was mixed. As we discuss the wastewater, which has been discharged from electroplating process, it is important and will be applied to the resources of metal in the urban mine.

  • The treatment of atopic dermatitis (AD) is challenging due to its complex etiology. From epidermal disruption to chronic inflammation, various cells and inflammatory pathways contribute to the progression of AD. As with immunosuppressants, general inhibition of inflammatory pathways can be effective, but this approach is not suitable for long-term treatment due to its side effects. This study aimed to identify a plant extract (PE) with anti-inflammatory effects on multiple cell types involved in AD development and provide relevant mechanistic evidence. Degranulation was measured in RBL-2H3 cells to screen 30 PEs native to South Korea. To investigate the anti-inflammatory effects of Parasenecio auriculatus var. matsumurana Nakai extract (PAE) in AD, production of cytokines and nitric oxide, activation status of FcεRI and TLR4 signaling, cell-cell junction, and cell viability were evaluated using qRT-PCR, western blotting, confocal microscopy, Griess system, and an MTT assay in RBL-2H3, HEK293, RAW264.7, and HaCaT cells. For in vivo experiments, a DNCBinduced AD mouse model was constructed, and hematoxylin and eosin, periodic acid-Schiff, toluidine blue, and F4/80-staining were performed. The chemical constituents of PAE were analyzed by HPLC-MS. By measuring the anti-degranulation effects of 30 PEs in RBL-2H3 cells, we found that Paeonia lactiflora Pall., PA, and Rehmannia glutinosa (Gaertn.) Libosch. ex Steud. show an inhibitory activity of more than 50%. Of these, PAE most dramatically and consistently suppressed cytokine expression, including IL-4, IL-9, IL-13, and TNF-α. PAE potently inhibited FcεRI signaling, which mechanistically supports its basophil-stabilizing effects, and PAE downregulated cytokines and NO production in macrophages via perturbation of toll-like receptor signaling. Moreover, PAE suppressed cytokine production in keratinocytes and upregulated the expression of tight junction molecules ZO-1 and occludin. In a DNCB-induced AD mouse model, the topical application of PAE significantly improved atopic index scores, immune cell infiltration, cytokine expression, abnormal activation of signaling molecules in FcεRI and TLR signaling, and damaged skin structure compared with dexamethasone. The anti-inflammatory effect of PAE was mainly due to integerrimine. Our findings suggest that PAE could potently inhibit multi-inflammatory cells involved in AD development, synergistically block the propagation of inflammatory responses, and thus alleviate AD symptoms.

  • Papilloma is the common benign tumor of the larynx and the incidence of its malignant change was variable. The authors recently experienced 2 cases of squamous cell carcinoma of the larynx which were considered to be transformed from laryngeal papilloma. Case 1. A 58 year old male patient visited O.P.D. of Department of Otolaryngology of Busan National University Hospital, because of hoarseness for 3 years on May 13th, 1980. At that time, local finding of indirect laryngoscopy revealed whitish hypertrophic papillomatous mass on both vocal cords and anterior commissure, and dirty gray white pseudomembrane on left aryepiglottic fold, and the result of biopsy was squamous cell papilloma. So the laryngeal papilloma was removed under suspension laryngoscopy and then he had no specific treatment in spite of being recommended 5-FU topical spray. On March 5th, 1981, he visited O.P.D. again because of progressive exacerbation of hoarseness with mild dyspnea and histopathological finding was revealed squamous cell carcinoma of the larynx. Seven days later from that day, he visited emergency room due to severe dyspnea, and emergency tracheostomy was performed on sitting position. On April 7th 1981, total laryngectomy was performed successfully and postoperative irradiation therapy was recommended. Case 2. A 47 year old male patient visited our O.P.D. because of hoarseness for 5 years on Sep. 27, 1978. At that time, local finding of indirect laryngoscopy revealed papillomatous mass on left vocal cord and left ventricle and result of biopsy was squamous cell papilloma. So he had been treated with 11 times removal of papilloma, topical spray of 5-Fu and estrogen for 3 years, but the papilloma had been recurred. On Sep. 9th, 1981, he visited O.P.D. because of severe dyspnea and emergency tracheostomy and biopsy was performed. The result of biopsy was squamous cell carcinoma of larynx and total laryngectomy was performed successfully.

  • We investigated the anti-wrinkle activity of an 80% ethanol extract of Curdrania tricuspidata leaves (CTL80) on ultraviolet-induced photoaging in hairless mice. Skin wrinkles were induced by 10 weeks of UVB-irradiation on the back of Skh-1 hairless mice three times a week. Mice were divided into ten groups; normal control (-UVB), UVB irradiated control group (+UVB), dietary groups (UVB+ascorbic acid 0.1%, UVB+CTL80 0.1%, UVB+CTL80 0.25%) and topical application groups (-UVB+base lotion (BL), UVB+BL, UVB+ascorbic acid 1%+BL, UVB+CTL80 1%+BL, UVB+CTL80 2%+BL). Wrinkle formation, histological changes, superoxide dismutase (SOD) activities, glutathione peroxidase (GSH-Px), and the expression of matrix metalloproteinases (MMP-1, MMP-3 and MMP-9) were analyzed. Wrinkles for the +UVB groups formed as a pattern of deep furrows and thick crests. Wrinkles with CTL80 treatment formed as a pattern of shallow furrows and thin crests, with wrinkle areas were lower than the +UVB group. In an antioxidant analysis of mouse blood, SOD and GSH-Px activities were significantly higher in the CTL80 topical application group compared to the +UVB group. The mRNA expression of MMPs in the +UVB group was significantly higher than the normal control group, and significantly lower in the CTL80-treated group. In conclusion, CTL80 exerted anti-wrinkle activity on ultraviolet-induced photoaging by regulating antioxidative defense systems and MMPs expression.

  • Moisturizers are the most prescribed products in dermatology. Treatment with moisturizers aims to maintain skin integrity and overall well-being by providing a healthy appearance. Moisturizers perform very important functions in baby care; however, there are few studies on the effects of moisturizers on the skin of infants. To investigate the effects of moisturizers on the skin of healthy full-term infants and toddlers, thirty-one healthy, full-term, 6- to 36-month-old infants and toddlers without any dermatologic conditions received moisturizer applied to the whole body except the eyes and diaper area after bathing twice daily for 4 weeks. Clinical assessments were conducted before treatment, immediately after the treatment period, and 1 and 4 weeks after treatment. At all visits, skin hydration, transepidermal water loss (TEWL), skin pH, and skin roughness were measured, the skin surface was photographed, and any adverse events were recorded. After using moisturizer, skin hydration significantly increased and TEWL and roughness significantly decreased. The skin pH was modified to mildly acidic and the skin surface was visually smoother than before treatment. There were no statistical significant differences of effects of moisturizers according to age and sex, and adverse events were not observed. The results of moisturizer application on the skin were increased skin hydration, recovery of barrier function, balancing skin pH within a mildly acidic range, and increasing the smoothness of the skin surface for 4 weeks.

  • EtOAc fractions of Magnolia obovata (M. obovata) Bark extracts were studied for the potential ingredient as a safe and effective whitening cosmetic material. The concentration of active substances honokiol was determined by HPLC. In vitro, the fractions reduced the extracellular and intracellular melanin contents in B16F10 cells in dose dependently and inhibited extracellular melanin secretion ($IC_{50}=11.05{\mu}g/mL$). The $12.5{\mu}g/mL$ treatment of maximum concentration effectively inhibited up to about 60% to the amount of extracullular melanin. Also, the $12.5{\mu}g/mL$ treatment of maximum concentration effectively inhibited up to about 59% to the amount of intracullular melanin ($IC_{50}=10.85{\mu}g/mL$). The $IC_{50}$ value of ${\alpha}-arbutin$ used as a positive control was $59.99{\mu}g/mL$. So, EtOAc fractions of M. obovata Bark extracts showed whitening effect when compared with the non-treatment group. In case of in vivo study, Cosmetic cream with EtOAc fractions of M. obovata Bark extracts was approved by Ethics committee of KDRI (IRB number: KDRI-IRB-1537). As a result in progress for skin sensitization as well as assessment of skin irritation through repeated patch test, skin allergens was identified as non sensitizing agents. Also, cosmetic cream with EtOAc fractions of M. obovata Bark extracts showed significant topical whitening effect and reliable skin safety when compared with the non-treatment group. In conclusion, EtOAc fractions of M. obovata Bark extracts may be a useful cosmetic ingredient for effective skin whitening.

  • Fifty-four dogs with otitis externa were enrolled in the study for the Evaluation of efficacy of a Hydrocortisone aceponate - Gentamicin - Miconazole otic combination ($Easotic^{(R)}$, Virbac, Carros, France). Otitis externa patients were treated by $Easotic^{(R)}$ once daily for 5 days and 2 days off treatment and evaluated on $7^{th}$ day. If otitis externa persisted, additional $Easotic^{(R)}$ treatment was administered once daily for 5 days and rested 2 days and reevaluated on $14^{th}$ day. For the evaluation of efficacy of $Easotic^{(R)}$, eight clinical signs were scored on a severity scale and infectious agents from ear sample were also graded using semi-quantitative scale at each visit. Sum of clinical scores and cytological scores was defined as Global Clinical Score. When $Easotic^{(R)}$ was applied once daily for 5 days, global clinical score was reduced 76.0%. When $Easotic^{(R)}$ was administered for 10 days, during first 5 days administration, 46.6% reduction of global clinical score was detected. During additional 5 days administration, 82.2% reduction of global clinical score was observed compared with Day 0. Any relevant adverse effect was not reported during the study in all cases. Thus, $Easotic^{(R)}$ treatment once daily for 5 days and 10 days appears to be effective and safe treatment for canine otitis externa.

  • Objectives : The purpose of this study is to examine the effects of external application of HC001 on atopic dermatitis. HC001, newly composed herbal medicine combinations contains 9 medicinal herbs which are known to have anti-inflammatory and anti-allergic effects. We investigated the anti-inflammatory effects of HC001 on atopic dermatitis-like skin lesions in mice. Methods : Seven-week-old BALB/c mice were sensitized with DNCB to develop atopic dermatitis. Animals were divide into three group: Normal, DNCB (Negative control group), HC001 (Experimental group, treated with DNCB and HC001). Skin sections were stained with H&E to measure the thicknesses of the epidermis and dermis, respectively. The expression of NF-${\kappa}B$ protein was measured by western blotting analysis in skin lesion. Results : Topical HC001 treatment significantly restored the skin thickening and hyperplasia of the epidermis and dermis compared with DNCB-sensitized group in histopathological analyse. In addition, HC001 inhibited the expression of NF-${\kappa}B$ protein increased in DNCB-induced atopic dermatitis-like skin lesions in mice. Conclusions : These results suggest that HC001 may be useful as an external application agent for atopic dermatitis based on reductions of various inflammatory responses.
