  • 6 년령 중성화 암컷 페르시안 고양이가 3개월동안 우안의 재발성 각막궤양, 각막혼탁, 각막 혈관화를 주증상으로 내원하였다. 병변은 그 기간동안 국소적인 항생제와 비스테로이드성 소염제 점안에 치료반응이 없었다. 우안에서 유루증, 안검경련과 같은 안구통증 증상이 확인되었다. 미세 틈새등 현미경 검사에서 우안의 각막 전체에 분홍색에서 흰색을 띄는 부종성의 불규칙한 덩어리와 미약한 결막염을 확인하였다. 임상증상을 통해 고양이 증식성 호산구성 각막염으로 잠정 진단하였다. 각막의 세포학적 검사결과에서 다수의 호산구와 비만세포가 관찰되어 잠정적으로 내렸던 진단을 확진하였다. 본 환자는 국소적인 항생-코르티코스테로이드 합제, 사이클로스포린 연고, 트리플루리딘 점안과 전신적인 L-lysine 의 경구투여로 치료하였다. 치료시작 18일 후 내원 시 병변은 눈에 띄게 호전되었다. 국소적인 코르티 코스테로이드와 사이클로스포린의 병용치료는 고양이 증식성 호산구성 각막염에 유용한 치료법으로 생각된다.

  • Medimin A는 경피 흡수성과 안정성을 높이기 위해 retinoic acid와 polyethylene glycol(PEG)를 결합시켜 개발한 비타민 A 유도체이다. Medimin A의 주름 완화 효과를 확인하기 위하여 콜라겐 합성능 및 임상 평가를 실시하였다. Invitro 콜라겐 합성능은 섬유아세포를 배양하여 생산되는 단백질 중에서, collagenase에만 특이적으로 분해되는 단백질에 함유된 [$^3$H]-proline의 양을 측정하여 평가하였으며, 임상 평가는 피부주형(replica)의 영상분석, 주름의 육안적 관찰, 피시험자의 자가 판단에 의하여 평가하였다. Medimin A를 섬유아세포에 처리한 결과 104% 농도에서 약 40%의 콜라겐 합성 증진을 보였다. Medimin A가 0.2%함유된 O/W 에멀젼을 10주간 피시험자에 도포한 결과, 피부 주형에서 가장 깊은 주름이 약 38.4% 가 감소되었으며, 육안적 관찰에 의한 눈가 주름은 25.5% - 44.1%가 감소되었다. 또한 피시험자의 자가 진단에 의하면 전체 피시험자 중 93%가 10주간 도포 후 주름이 호전되었다고 응답하였다. 이상과 같은 결과에서, Medimin A는 객관적 평가법(in vitro 콜라겐 합성능, 피부 주형의 영상분석) 및 주관적 평가법(육안적 관찰, 피시험자의 자가 진단)에서 모두 유의하게 주름을 완하시키는 물질임이 확인되었다.

  • Activation of the NLRP3 inflammasome is critical for host defense as well as the progression of inflammatory diseases through the production of the proinflammatory cytokine IL-1β, which is cleaved by active caspase-1. It has been reported that overactivation of the NLRP3 inflammasome contributes to the development and pathology of acne vulgaris. Therefore, inhibiting activation of the NLRP3 inflammasome may provide a new therapeutic strategy for acne vulgaris. In this study, we investigated whether auranofin, an anti-rheumatoid arthritis agent, inhibited NLRP3 inflammasome activation, thereby effectively treating acne vulgaris. Auranofin suppressed NLRP3 inflammasome activation induced by Propionibacterium acnes, reducing the production of IL-1β in primary mouse macrophages and human sebocytes. In a P. acnes-induced acne mouse model, injection of P. acnes into the ears of mice induced acne symptoms such as redness, swelling, and neutrophil infiltration. Topical application of auranofin (0.5 or 1%) to mouse ears significantly reduced the inflammatory symptoms of acne vulgaris induced by P. acnes injection. Topical application of auranofin led to the downregulation of the NLRP3 inflammasome activated by P. acnes in mouse ear skin. These results show that auranofin inhibits the NLRP3 inflammasome, the activation of which is associated with acne symptoms. The results further suggest that topical application of auranofin could be a new therapeutic strategy for treating acne vulgaris by targeting the NLRP3 inflammasome.

  • 여드름은 면포, 구진, 낭종, 결절, 색소 침착 등 다양한 피부병변으로 나타나는 모낭피지선의 만성 염증질환으로 사춘기부터 성인기까지 발생 연령대가 다양해지고 있다. 한편, 약물 부작용으로 여드름이 발생하기도 하는데, 표피성장인자(epidermal grouwth factor, EGF) 수용체 억제제 항암제를 사용할 경우 75 ~ 100%에서 여드름양 모낭염이 발생된다고 보고되고 있다. 여드름의 치료로 항생제, 레티노이드 경구 복용 및 외용 약제 도포 등 다양한 방법이 이용되고 있다. 그러나 최근 들어 레티노이드 기형 유발 가능성 및 Propionibacterium acne의 항생제 내성률 증가는 기존 치료의 한계로 여겨진다. 따라서 본 연구는 최근 여드름양 발진에 효과가 있다고 알려진 EGF를 함유한 외용제가 여드름 치료에 미치는 효과와 안정성을 평가하였다. 한국 성인 10 ~ 29세 23명을 대상으로 EGF 함유 제품(트러블컨트롤 EGF)과 3종 제품(트러블컨트롤 클래리파잉 클렌징폼, 트러블컨트롤 올-클리어 필링토너, 레드롤 카밍 모이스처)을 하루 두 번 사용하도록 하였다. 사용 후 영상 피지량, 경표피수분손실량, 피부 홍조 측정, 전문가 육안 평가, 사용 후 만족도 설문조사를 평가하였다. 최종 측정 시, 피부 피지량, 경피수분손실량, 피부 홍조가 통계학적으로 감소하였으며, 전문가 육안 평가에서 여드름 병변(면포, 구진)도 통계학적으로 감소하였다. 연구동안 심각한 부작용은 관찰되지 않았다. 표피성장인자 함유 외용제는 경도의 여드름에 안전하면서도 효과적으로 사용할 수 있을 것으로 생각된다.

  • 중추신경계와 말초신경계의 손상으로 인한 다양한 기전에 의해서 신경병성 통증이 생길 수 있다. 특정한 질병과 관련된 기전에 의해서 생기는 경우는 거의 없고, 진단과는 상관없이 한 환자에서 여러 가지 기전이 동시에 관여하여 생긴다. 신경병성 통증은 신경학적 검사와 환자의 문진으로부터 쉽게 진단할 수 있으나 치료는 아직 만족할 만하지 못하다. 신경병성 통증의 치료가 어렵다 하더라도 의사가 치료시 문제점을 완전히 이해하고 있다면 적절한 치료에 도달될 수 있을 것이다. 적절한 약물의 선택은 환자마다 효과가 있는 약제, 용량, 혈중농도 등이 각기 다르기 때문에 치료의 시도와 실패의 반복을 통해서 얻어질 수 있다. 효과가 있다고 알려진 각 약물들의 적절한 치료연구는 신경병성 통증의 약물치료에 있어 핵심일 것이다. 삼환계 항우울제는 일차약물로 알려져 있고 이에 대한 효과가 만족스럽지 못할 경우에는 항경련제, 국소마취성 항부정맥제제, clonidine, 마약성 진통제, 국소도포제 순으로 사용해 볼 수 있다. Venlafaxine, nefazodone 같은 항우울제가 최근에 삼환계 항우울제 보다 부작용이 적고 비슷한 효과가 있으며, 항경련제인 gabapentine도 효과있는 약물로 널리 사용되고 있다.

  • DA-3711 is a novel anti-wrinkle agent containing growth factors derived from culture medium of artificial human skin. Photoprotective effect by DA-3711 against chronic UVB (ultraviolet B)-induced skin damage was investigated in hairless mice model. Methods: After hairless mice were irradiated to induce photodamage for 8 weeks with UVB, grouped mice were treated topically once a day with lotion base, DA-3711 (30% or l5%), Cylasphere retinol$^{\circed{R}}$ (2500 I.U.), NouriCel$^{\circed{R}}$ along with concomitant exposure to UVB for further 8 weeks. Then mice were sacrificed to assess photodamage-protective effect by replica analysis, biochemistry and histology. DA-3711 of 30% lotion significantly reduced UVB radiation-induced wrinkling, histological alterations and increased collagen contents. Whereas DA-3711 of l5% lotion and NouriCel$^{\circed{R}}$ treatment showed a partial protective effect on skin wrinkle, epidermal and dermal thickness, and collagen content, Cylasphere retinol$^{\circed{R}}$ showed no protective effects. These results demonstrate that topical application of DA-3711 can alleviate UVB-induced photodamage and potentially be used for reduction of UVB-induced photodamage.

  • External lyogels containing prostaglandin $E_1$ ethyl ester $(PGE_1-EE)$, a prodrug of prostaglandin $E_1\;(PGE_1)$ as a therapeutic agent for erectile dysfunction, were formulated to overcome the aqueous instability and enhance the percutaneous absorption. Lyogels of $PGE_1-EE$ were prepared with ethanol (EtOH)/proplyene glycol (PG) cosolvent system as a vehicle, cineol as an enhancer, and hydroxypropylcellusose as a gelling agent. In vitro percutaneous absorption studies were performed to determine the rate of $PGE_1$ absorption through rat or hairless mouse skin. The permeability of $PGE_1-EE$ lyogel with enhancer was 16-fold greater than that of lyogel without enhancer. Cosolvent produced 9-fold increase in percutaneous absorption. Pharmacodynamic effects of lyogels were evaluated in mature male cats in terms of intracavernosal pressure (ICP). Lyogels containing 0.1 % of $PGE_1-EE$ showed higher ICP compared to intraurethral preparation of $PGE_1$ (1 %) and enhancer-free control lyogel. The shelf-life $(t_{10%})$ of lyogel at refrigerated condition $(4^{\circ}C)$ was calculated as 928 days, which is 4.2 times longer than that of control hydrogel. As a result, $PGE_1-EE$ was formulated successfully to a lyogel system with a selective enhancer and cosolvent system for the topical delivery of $PGE_1$.

  • To date, research on the regulation of melanogenesis has focused on factors which affect tyrosinase, the rate-limiting enzyme in the melanogenic pathway, by searching for chemicals which competitively inhibit tyrosinase function. Many types of tyrosinase inhibitors have been developed, but no satisfactory results have been made clinically until now, To find a new whitening agent, which effectively inhibits melanogenesis, we synthesized several compounds and selected compounds by cell-based assay system. Finally, 3, 4, 5-trimethoxy cinnamaie thymol ester(TCTE, Melasolv) was selected and the effects of TCTE on melanogenesis were investigated. Treatment of mouse-derived melanocyte melan-a cells with TCTE results in a marked down-regulation of tyrosinase activity. 80% decrease of tyrosinase activity occurs with 30uM TCTE treatment for 72 hours without affecting cell growth. The inhibition of tyrosinase activity is dose-dependent and melanin content was also decreased to 40%. From the in vitro tyrosinase assay using cell extract, TCTE does not act as a direct inhibitor of the enzyme. Treatment of melan-a cultures with TCTE blocks the increase in tyrosinase activity by either forskolin, 3-isobutyl-1-methtyl-xanthine. TCTE decreased the expression of tyrosinase, TRP-1 without effects on TRP-2 protein expression through the down regulation of tyrosinase and TRP-1 mRNA. From the results of cAMP immunoassays, intracellular levels of the cyclin nucleotide are unaffected in cells treated with TCTE. The inhibitory effects of melanin synthesis were also shown in reconstitute human epidermis model by topical application. These findings suggest that TCTE can be used for studying the regulation of melanogenesis and depigmenting agent.

  • Wogonin (5,7-dihydroxy-8-methoxyflavone) is a down-regulator of cyclooxygenase-2 and inducible nitric oxide synthase expression, contributing to anti-inflammatory activity in vivo. For further characterization of modulatory activity on ploinflammatory gene expression in vivo, the effect of wogonin was examined in this experiment using animal models of skin inflammation. By topical application, wogonin inhibited an edematic response as well as ploinflammatory gene expression against contact dermatitis In mice. Wogonin inhibited ear edema ($19.4-22.6\%$) at doses of $50-200\;{\mu}g$/ear and down-regulated interleukin-$1{\beta}$ induction ($23.1\%$) at $200{\mu}g$/ear in phenol-induced simple irritation. Wogonin ($2{\times}50-2{\times}200{\mu}g$/ear) also inhibited edematic response ($51.2-43.9\%$) and down-regulated ploinflammatory gene expression of cyclooxygenase-2, interleukin-$1{\beta}$, interferon-$\gamma$, intercellular adhesion molecule-1 and inducible nitric oxide synthase with some different sensitivity against picryl chloride-induced delayed hypersensitivity reaction. All these results clearly demonstrate that wogonin is a down-regulator of ploinflammatory gene expression in animal models of skin inflammation. Therefore, wogonin may have potential for a new anti-inflammatory agent against skin inflammation.

  • Malachite Green (MG), a toxic chemical used as a dye, topical antiseptic and antifungal agent for fish, is highly soluble in water, cytotoxic to various mammalian cells and also acts as a liver tumor promoter. In view of its industrial importance and possible exposure to human beings, MG possesses a potential environmental health hazard. So, we performed with HepG2, a human hepatocellular carcinoma cell line, to identify the differentially expressed genes (DEGs) related to toxicity of MG. And we compared gene expression between control and MG treatment to identify genes that are specifically or predominantly expressed by employing annealing control primer (ACP)-based $GeneFishing^{TM}$ method. The cytotoxicity $(IC_{20})$ of MG was determined above the $0.867{\mu}M$ in HepG2 cell for 48 h treatment. And the DEGs of MG were identified that 5 out of 6 DEGs were upregulated and 1 out of 6 DEGs was down-regulated by MG. Also, MG induced late apoptosis and necrosis in a dose dependent in flow cytometric analysis. Through further investigation, we will identify more meaningful and useful DEGs on MG, and then can get the information on mechanism and pathway associated with toxicity of MG.
