Ethanol extracted propolis (EEP) was mixed with honey (honeypolis) to dissolve well in water and in vitro skin irritation test was conducted. In vitro method is designed to predict and classify the skin irritation potential of a chemical by assessment of its effect on $EpiDerm^{TM}$, a reconstituted three-dimensional human epidermis model. Cytotoxicity is expressed as the reduction of mitochondrial dehydrogenase activity measured by formazan production from MTT after a 60 min exposure period. In this study under the given conditions honeypolis showed no irritant effects. Honeypolis meets acceptance criteria if: mean absolute OD 570 nm of the three negative control tissues is ${\geq}0.8$ and ${\leq}2.8$, mean relative tissue viability of the three positive control tissues is ${\leq}20%$, standard deviation of relative tissue viability obtained from each three concurrently tested tissues is ${\leq}18%$. Honeypolis is therefore classified as "non-irritant" in accordance with UN GHS "No Category".

2000년 이후 국내에 등록된 농약제품을 대상으로 원제 및 그 원제로 제조된 농약의 자극성 및 감작성에 대한 연관성을 연구하여 농약재등록, 신규등록 및 농약관리시 자극성 예측, 시험성적서 요구 결정 등에 대한 이용 가능성을 타진하고 농약관리의 기초 자료로 활용하기 위해 수행되었다. 농약의 자극성 및 감작성성적은 농약시험성적 정보집 및 농약등록 시 제출된 자료 등을 참고하여 원제 148성분 및 제품 149종의 자극성 및 감작성의 양성반응 빈도, 제형 간 반응차이, 원제와 제품간의 연관성 등을 조사 분석하였다. 원제 148성분 중 피부 자극성 133종, 안구 자극성 132종, 피부 감작성 97종의 성적이 이용되었으며, 항목별로 피부자극성 25(18.8%)종, 안구자극성 62(47%)종, 피부감작성 20(20.6%)종이 경도 이상의 양성반응을 보였다. 또한 149 품목 중 피부자극성 148종, 안구자극성 149종, 피부감작성 140종의 성적으로 분석한 결과 피부자극 22(14.9%), 안구자극 58(38.9%), 피부감작성 33(23.6%)품목이 경도 이상의 양성반응을 나타내었다. 동일제형 10품목 이상이 조사된 10종을 제형별, 독성반응별로 조사 분석하였다. 분석결과 원제와 제품간의 연관성은 피부자극성 73.1%, 안구자극성 44.7%, 피부감작성 66.2%로 분석되었으며, 성분함량간의 자극성 및 감작성은 아무런 상관성이 없는 것으로 판단되었다. 이상 원제와 제품간의 자극성 및 피부감작성에 관여하는 몇 가지 요인을 조사 분석한 결과 피부자극성 및 피부감작성은 원제와 제품간 각각 73.1%, 66.2%의 높은 상관성을 보였으나, 안구자극성은 제형 의존적인 것으로 판단되어 추후 더 많은 농약에 대하여 원제의 자극성성적, 제형특성 등을 참고하여 분석하면 자극성시험 수행 여부 결정을 위한 스크리닝 단계에 이용 가능할 것으로 판단되었다.

Objectives: The major objective of this study is the oral dose toxicity test and skin irritation test of eco-friendly plasticizer using crude glycerol derived from the biodiesel process. Methods: Glyceroldiacetate laurate(GDL) was synthesized from glycerol monolaurat(GML) and acetic acid. The synthesis of the GDL plasticizer was measured with nuclear magnetic resonance spectroscop(NMR) and FT-IR(Fourier Transform Infrared Spectrometer). To provide information on the safety of GDL, we carried out an oral dose toxicity test for GDL in Sprague-Dawley rats. Also, we carried out a skin irritation test for GDL in New Zealand White rabbits. Results: The oral dose toxicity test in Sprague-Dawley rats showed that GDL is a non-toxic material. The result of the skin irritation test on New Zealand White rabbits showed that GDL is non-irritating. Conclusions: From the results of oral dose toxicity test and skin irritation test, we concluded that the developed plasticizer showed excellent eco-friendly property. Based on our results, we confirmed the development of an eco-friendly non-phthalate plasticizer. Applicability for PVC toys and food and drug packaging materials was found.

Carthami tinctorii Fructus is known for its good effect on diseases such as fracture, menorrhalgia, menoschesis, puerperium aneilema and so on. The study of irritation and toxicity of Carthami oil aquapuncture solution applied topically to the skin and the eye mucous membrane were carried out to prove the safety of Carthami oil aquapuncture solution in clinical use. Animal for the research was the rabbit and the solution for the test was made from Carthami semen. 6 animals were used for the skin test and 9 animals were used for the eye mucous membrane test. In results, both tests proved that Carthami oil aquapuncture solution makes no irritable reaction on skin and eye mucous membrane of rabbit. We consider that this result is helpful for saying about the safety of Carthami oil aquapuncture solution in clinical use.

In the present study, we evaluated the free radical scavenging and xanthine oxidase inhibitory activities exhibited by extracts obtained from the dried stems (and leaves) of Lespedeza bicolor We also assessed its potential irritation activities with regard to cosmetic use. When the DPPH radical scavenging activities of L. bicolor were assessed at six different concentrations (0, 50, 100, 250, 500 and 1000 ${\mu}g/ml$), the concentration of L. bicolor required to inhibit DPPH radical formation by $50\%$ was found to be $164.90{\mu}g/ml$. The effects of L. bicolor on the inhibition of xanthine oxidase were determined at seven different concentrations. The $50\%$ effective concentration was found to be $282.75{\mu}g/ml$. In the skin irritation test, all animals survived for the duration of the study, and all exhibited normal gains in body weight. The control sites exhibited no response to the control procedures. No edema, erythema, or eschar formation was observed in any of the tested rabbits. In the ocular irritation study, all of the rabbit eyes remained normal. In summary, L. bicolor extracts were considered to be non-irritating to the skin and eye.

본 연구는 흑마늘을 기능성 화장품 소재로 활용하기 위하여 그 기능성을 in vitro에서 tyrosinase 및 elastase 저해 활성을 측정한 결과 피부노화에 관여하는 두 효소의 활성을 모두 저해하였다. 흑마늘 추출물을 hartley계 기니픽 수컷을 사용하여 피부 1차 자극 실험을 실시한 결과 1차 피부자극지수(P.I.I.)가 0.23으로 practically non-irritation(비자극성)에 해당하는 자극으로 피부 자극이 거의 없었음을 알 수 있었다. Maximization test법으로 피부 감작성을 확인한 결과 시험물질에 의한 홍반과 부종 등이 전혀 유발되지 않았다. 이상의 결과로부터 흑마늘 추출물에 대한 기니픽의 피부 감작율은 0%로, 피부에 대한 피부 감작성이 없는 것으로 확인되었다. 따라서 이러한 본 연구의 결과는 흑마늘 추출물이 기능성 화장품 소재로 피부노화를 억제하는 기능성과 안전성확보된 소재임을 추정할 수 있었다.

A novel synthetic hexapeptide (SFKLRY-$NH_2$) that displays angiogenic activity has been identified by positional scanning of a synthetic peptide combinatorial library (PS-SPCL). This study was carried out to investigate the irritation of the SFKLRY-$NH_2$ on the skin. The tests were performed on the basis of Korea Food and Drug Administration (KFDA) guidelines. In results, cell toxicity is not appeared for SFKLRY-$NH_2$ in HaCaT cells and B16F10 cells. SFKLRY-$NH_2$ induced no skin irritation at low concentration ($10{\mu}m$), mild irritation at high concentration (10mM). We consider that this result is helpful for saying about the safety of SFKLRY-$NH_2$ in clinical use.

The present study was carried out to investigate the antibacterial activity against Staphylococcus aureus with antibiotic-resistance in vitro and the skin irritation in rabbits with surfactin produced by Bacillus subtilus Complex BC1212. The antibacterial activities of selected antimicrobial agents (surfactin, amoxacillin, colistin, norfloxacin and streptomycin) were evaluated by using the broth microdilution method. As the results, the minimum inhibitory concentration (MIC) of the surfactin was less than 15.6 ㎍/ml. In the skin irritation test, two out of 4 rabbits showed very slight edema at 24 h after the administration of surfactin, and then recovered at 72 h. The change of body weight was normal during the skin irritation test. The primary irritation index in accordance with the Draize evaluation of topical reaction was calculated to be '0.125', which meant not irritating. Based on these results, it could be concluded that the test agent, surfactin, was a non-irritant. We could also think that the surfactin may be useful for the treatment of S. aureus infections such as bovine mastitis.

본 연구는 SD 계통의 랫드에서 국화 염료인 백색국화, 백색국화 잎과 줄기, 황색국화의 급성경구독성 및 피부자극성을 평가하기 위해서 시행하였다. 수컷 랫드에 처치한 물질은 백색국화, 백색국화 잎과 줄기, 황색국화를 각각 1 ml/kg, 2 ml/kg를 D.W에 용해시켜 단회 경구 투여하였으며, 수컷 SD rats에 투여 후 14일 동안 관찰하였으며, 피부자극성 시험은 피부의 찰과 및 비찰과부의 대조부, 처치부에 국화 염료를 처치하여 3일 동안 관찰하였다. 단회 경구 투여 및 피부 자극성 시험 후 국화 염료의 안전성을 확인하기 위해 체중과 사료 섭취량, 임상증상, 안과학적 검사, 사망률, 피부자극성을 관찰하고, 랫드 피부에서의 병리조직학적 변화를 관찰하였다. 체중, 사료섭취량, 병리조직학적 변화가 대조군과 비교시 유의적인 변화가 나타나지 않았다. 또한 피부자극성을 확인 한 결과 1차 자극 지수가 0으로 비자극성 물질로 분류되었다. 따라서 본 연구를 통하여 국화에서 추출한 염료가 급성 경구독성 시 안전한 물질이며, 피부 자극성을 야기 하지않는 물질로 평가된다.
