  • 톨루엔-2,4-디이소시아네이트, 톨루엔-2,6-디이소시아네이트 각각 또는 두 이성체 혼합물(TDI)에 대하여 TLV-TWA는 0.005 ppm, TLV-STEL은 0.02 ppm으로 직업적 노출기준을 권고하고 있다. 본 수치는 호흡기에 대한 영향과 과민성 반응에 대한 높은 발생 가능성을 최소화하기 위한 것이다. 산업현장에서 증기상 TDI 물질은 점막, 호흡기계에 심한 자극을 일으켜 천식과 같은 증후군 등 급성 발작을 유발한다. 고농도에 노출시 심한 기관지 경련, 폐렴, 폐부종, 두통, 불면증과 기관지염으로 이어질 수 있다. TDI에 상당 부분 노출되면 대부분의 사람들은 위와 같은 건강 영향을 경험하게 된다. 심지어 처음 노출되었을 경우에도 발생된다. TDI 노출 관련 연구자들은 일반 근로자들이 0.02 ppm 수준 정도로 가끔 노출되는 경우 건강 영향을 받지 않으나, 0.02 ppm이 무영향 수준으로 간주될 수 있는 그 어떠한 증거도 없다고 결론을 내렸다. TDI에 일단 감작되면 몇몇 근로자들은 노출 중단 후에도 몇 년 동안 건강 영향 증세가 지속된다. 따라서 감작제 표기는 호흡 노출을 통한 알레르기성 감작 증세의 명확한 증거로서 권고된다. A4(비발암성 물질) 표기는 생쥐와 흰쥐들을 대상으로 수행된 위장관 투여 연구와 흡입 연구들을 통해 얻어진 동물 노출 데이터에 근거하여 설정되었다. 불충분한 데이터로 피부 표기는 권고되지 않았다.

  • In the present study, we examined eye irritation oj six anti-wrinkle agents (ascorbic acid, glycolic acid, all trans-retinoic acid, ginseng extract, retinol, EB). We also compared eye irritation with skin irritation and cytotoxicity in HaCaT cells by these agents. The highest eye irritation was found in glycolic acid, but all trans-retinoic acid showed the highest skin irritation. The rank of eye irritation was not correlated with the cytotoxicity of agents. This result shows that eye irritation potency by these agents were not correlated with skin irritation potency, and cytotoxicity in HaCaT cells.

  • Phthalates are widely used as plasticizers to impart softness and flexibility to normally rigid polyvinylchloride products. However, there are not much studies jar dermal and ocular irritation toxicity of phthalates. So we investigated the skin or eye irritation effect of some phthalates which was not reported. The primary skin irritation of diethyl phthalate (DEP), diisodecyl phthalate (DIDP), diisononyl phthalate (DINP), dipropyl phthalate (DPP) and dipropyl phthalate (DPrP) was studied. The ocular irritation of dibutyl phthalate(DBP), DIDP, DINP, DPP and DPrP was also studied. DEP, DIDP, DINP, DPP, and DPrP were found to be non-irritating to the skin of the test animals. DBP, DIDP, DINP and DPP were found to be non-irritating to the eye of the rabbits. DPrP caused the slight irritations to the eye in 1 or 2 days after treatment but irritation of the animals was soon recovered.

  • The study of irritation and toxicity of honeybee(Apis mellifera. L) venom collected by a bee venom collector applied topically to the skin and mucous membrane were carried out to prove the safety of honeybee venom in clinical use. Animal for the research was the rabbit and the solution for the test was made from honeybee venom. Six animals were used for the skin test and nine animals were used for the eye mucous membrane test. In results, both tests proved that honeybee venom 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 honeybee venom in clinical use.

  • 구제역(Foot and Mouth Disease)은 우제류(偶蹄類; 발굽이 둘로 갈라 진 동물)에 구제역 바이러스가 감염되어 발생하는 급성, 열성의 전염병이다. 감염 시입과 제부(발굽)의 점막 및 피부에 수포를 형성하는 것이 특정이다. 이 질병은 소, 돼지, 염소, 산양, 사슴, 산돼지, 코끼리, 기린 등 70 여종이상의 동물에 감염되어 발육, 비유, 운동, 번식 등의 장애를 유발한다. 이 질병은 감수성동물이 많고, 전염력이 강하며, 바이러스형이 다양하여 방역에 극히 어려움을 나타내는 질병이다. 현재 세계동물위생기구(World Organization for Animal Health, OIE, 국제수역사무국)에서 발생시 보고하도록 규정하고 있는 질병으로, 국내에서도 제1종 가축 전염병으로 규정하여 국가에서 관리하는 질병이다. 구제역 비발생국에서는 발생국으로 부터의 가축, 축산물들의 수입금지나, 엄격한 검역조치를 취할 수 있어 국제교역에 많은 지장을 주는 질병이다. 이에 본고에서는 이러한 구제역에 대하여 자세히 알아보고, 이에 대한 효율적인 방역 대책이 무엇인가를 생각해보고자 한다.

  • Hereditary hemorrhagic telagiectasia (HHT), which is characterized by the classic triad of mucocutaneous telangiectases, arteriovenous malformations (AVMs) and inheritance, is an autosomal dominant disorder. The characteristic manifestations of HHT are all due to abnormalities of the vascular structure. This report deals with the case of a 14-year-old girl with typical features of HHT that include recurrent epistaxis, mucocutanous telangiectases, pulmonary and cerebral AVMs and a familial occurrence.

  • The objective of this study was to observe the healing of skin and mucosal grafts, comparing with the control sites. Six adult dogs were divided into two groups of three. Mucosal defects were created in all four quadrants, and the left side was used as a control. In the Group I animals, a split-thickness skin from the chest was grafted, and in the group II animals, a split-thickness mucosa from the buccal cheek was grafted into the mouth. Gross and microscopic examination was done at 3, 7, 14, 28, 42 days. The results were as follows. 1. Wound epithelization was accelerated in the supraperiosteal grafts. 2. After healing, the grafted skin was unnatural to the oral cavity, showing grayish-white color, hair, and sebaceous gland. But the mucosal grafts could not be discriminated from the adjacent mucosa. 3. the grafting on the cortical bone failed.

  • 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.

  • Eye irritation, primary skin irritation and skin sensitization tests for Aloewhite were tested in New Zealand White rabbits and Hartley guinea pig. In primary skin irritation test of male New Zealand White rabbits, body weights were not significantly changed and Primary Irritation Index (PII) was O.47, indicating Aloewhite as mildly irritating material. In ocular irritation test, any injury on iris, conjunctival membrane, and cornea in New Zealand White rabbits was not observed. No injuries of the ocular mucous membrane were also recorded. Skin sensitization was tested in guinea pig after intradermal and epicutaneous induction and graded 1 with zero % sensitization rate. These results indicate that Aloewhite was not considered to be irritant in test organs of animals.
