Major symptoms of al1ergic rhinitis are nasal obstruction, sneezing and watery rhinorrhea. Onpyetang has been used to treat for nasal obstruction, which is one of the symptoms of allergic rhinitis. This Experimental study was done to research effects of Onpyetang and transformed Onpyetang(Allii Radix is deducted from Onpyetang) on the anti-allergic effects. We have studied the vascular permeability response induced by serotonin and histamine, the contact dermatitis response induced by picryl chloride, the delayed type hypersensitivity response to SRC, the mice paw edema induced by carrageenin, the writhing syndrome induced by $0.7\%$ acetic acid, and the rectal temperature in febrile rats induced by yeast. The results were as follows : 1. In the vascular permeability response to intradermal serotonin and histamine. Onpyetang proved significant inhibitory effect(P<0.05, p<0.001) But transformed Onpyetang proved significant inhibitory effect only to histamine(P<0.05) 2. In the contact dermatitis response induced by picryl chloride, Onpyetang and transformed Onpyetang proved significant inhibitory effect.(P<0.05, P<0.05) 3. In the delayed type hypersensitivity response induced by SRC, Onpyetang and transformed Onpyetang proved significant inhibitory effect on mice paw edema.. (P<0.05, P<0.05) 4. In the delayed type hypersensitivity response induced by SRC, Onpyetang proved significant inhibitory effect to serum IgE.(P<0.01) But transformed Onpyetang proved insignificant inhibitory effect on serum Ig E. 5. In the mice paw edema induced by carrageenin, Onpyetang and transformed Onpyetang proved significant anti-inflammatory effect. (P<0.01, P<0.01) 6. In the writhing syndrome induced $0.7\%$ acetic acid, Onpyetang and transformed Onpyetang proved significant analgestic effect. (P<0.01, P<0.01) 7. In the rectal temperature in febrile rats induced by yeast, Onpyetang and transformed Onpyetang proved significant anti-pyretic effect.(P<0.001, P<0.01) according to this result Onpyetang was conclude to be effective on anti-allergic, anti-pyretic, anti-inflammatory and analgestic action. but transformed Onpyetang(Allii Radix is deducted from Onpyetang) was not effective on the vascular permeability response to intradermal serotonin and increasing Ig E of delayed type hypersensitivity response induced by SRC. In addition, transformed Onpyetang is not effective as Onpyetang. More study should be done about the role of Allii Radix.

Inhibitory effects of allergic contact dermatitis of hot water extract of Duchung (Eucommia ulmoides Oliver) leaf, bark and stem growing at Sancheong-gun were investigated for female BALB/c mouse induced by repeat elicitation of DNCB (2,4-dinitro-chlorobenzene). Skin reactions, consisting of increased ear thickness and the presence of ear inflammation, were observed in mice treated with DNCB and Duchung. Weight of lymph node, spleen and thymus in mice treated with Duchung extracts were lower than that of mouse treated with DNCB. Ear weight of mouse treated with Duchung extracts was decreased by increasing the concentration of sample as compared to control group and dropped as low as control level at 1,000 mg/kg. Ear thickness became thinner as test time on Duchung extract progressed. MDA (malondialdehyde) contents in liver tissue were not different in sample group with DNCB group, but were different in ear tissue. NO (nitric oxide) contents was decreased in Duchung extract groups at serum and ear tissues as compared to 1% DNCB group. In the present study, the results suggested that Duchung extract inhibits inflammatory response and oxidative damage induced DNCB allergen.

Background: Benzalkonium chloride (BKC) has been extensively used as a preservative in industrial products and in hygiene, medical, and cosmetic applications. Humidifier disinfectant (HD) products containing BKC have been used in South Korea. Objectives: This study was aimed to review types of products containing BKC, to summarize the regulations in the US, EU, Japan, and South Korea, and to review the health effects associated with the use of HD. Methods: We reviewed and summarized documents which were searched through PubMed and Google Scholar with the key words: BKC and asthma/contact dermatitis, humidifier disinfectant-associated lung injury (HDLI), and more. Results: Regulations in most countries including South Korea do not allow its use as disinfectants in spray-type of products for medicine, cosmetics, and household products. Two types of HD containing BKC (800~1,270 ppm) were marketed in South Korea from 1996~2003. Health effects reported from people who used products containing BKC were allergic contact dermatitis, erythema, and respiratory disease, including asthma. Two people who responded as HD users containing BKC only were confirmed to have developed asthma. HD-associated lung injury (HDLI) was reported by consumers who used both HD containing polyhexamethylene guanidine (PHMG) and HD containing BKC. Conclusions: In conclusion, the use of BKC as a biocide has to be controlled considering the route and pattern of exposure. Products containing BKC as preservatives were reviewed with exposure routes and sites in the human body such as skin, eyes, and the respiratory tract. HD containing BKC was clinically evaluated to be associated with asthma.

Lymph node tissues of BALB/C mouse treated with DNCB were immunohistochemically observed to investigate the activation of cell mediated immunity in lymph node of murine with allergic contact dermatitis. The inguinal region of BALB/C mice were sensitized by one application of $25{\mu}l$ of 5% 2,4-dinitrochlorobenzene(DNCB) onto an abdominal skin and 2 weeks later, the mice were challenged with $4{\mu}l$ of 2.5% DNCB. The inguinal lymph node were obtained at hour 24, 48, and 72 after 2nd DNCB treatment and embedded with paraffin, and then stained by following ABC method that used monoclonal antibody including L3T4(CD4), Ly2(CD8), IL-2R(CD25). The distribution of helper T lymphocytes, cytotoxic T lymphocytes and IL-2 receptors began to increase at hour 24 after after 2nd DNCB treatment and these increase appeared in paracortical area and medullary sinius. These increase were greatest at hour 48. These results indicated that the IL-2 secretion began to increase by activation of helper T lymphocytes in lymph node of DNCB re-exposure area and subsequently to activate suppress T lymphocytes.

The purpose of this research was to investigate the effects of Bopaewon-tang (BT) on allergic reaction. In the present study, we examined the effect of BT on type 1 and type tV allergic reaction. BT (500 mg/kg) did not affect the systemic anaphylaxis induced by compound 48180 and the passive cutaneous anaphylaxis induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin in vivo. Also, BT did not affect the release of histamine from peritoneal mast cells in rats. In addition, BT did not affect the permeability of evans blue into peritoneal cavity, but inhibited the writhing syndrome induced by acetic acid. BT inhibited the delayed type hypersensitivity induced by SRBC and the contact dermatitis induced by dinitrofluorobenzene. These results indicate that BT may be useful for the prevention and treatment of type IV allergy related disease.

Objectives : This experimental research has been done to study the effects of herbal-acupuncture with Juglandis Semen on the anti-allergic reaction. Methods : ICR mice were injected intraperioneally with compound 48/80 to induce the immediately type hypersensitivity (anaphylaxis). ICR mice were sensitized by PC and SRBC to induce the delayed type hypersensitivity. Sprage-Dawley rats were injected subcutaneously with egg albumin to measure the WBC. ICR mice and Sprage-Dawley rats were injected with Juglandis Semen herbal-acupuncture for the anti-allergic reaction test. Results : 1. In the restraint effect of systemic anaphylactic reaction, the mortality of mice decreased 20% each before 10 minutes and after 5 minutes. 2. In the contact dermatitis induced by PC, both Treat Ⅰand Treat Ⅱ group showed significant(p<0.01, p<0.05) decrease in comparison with the Control group, and also Treat Ⅲ group showed significance(p<0.005). 3. In the delayed type hypersensitivity in mice challenged by SRBC, Treat Ⅰ group showed significant(p<0.05) decrease in comparison with the Control group, and there was significance(p<0.05, p<0.05) in Treat Ⅲ and Treat Ⅳ group. 4. The change of the WBC in allergic rats induced by egg albumin showed significant(p<0.01, p<0.05, p<0.05) decrease in Treat Ⅰ, Treat Ⅱ and Treat Ⅲ group. Conclusions : The restraint effects of Juglandis Semen herbal-acupuncture on the anti-allergic reaction showed significance statistically. And also allergic group treated with $BL_{17}$ acupuncture (Treat Ⅲ group) showed same results.

We investigated the 1,004 workers who worked in a automobile factory to study the epidemiologic characterists of dermatoses due to cutting oils. Among the workers, 667(66.4%) answered the questionaire. They are belong to 5 departments of the factory-the Engine-Work(258 workers), Gasoline engine Assembly(210), Diesel engine Assembly(96), Power train Work(86), Power train Assembly(17). We measured the oil mist concentration in air of the departments and examined the workers who had dermatologic symptoms. The results were follows; 1) Oil mist concentration ; Of all measured points(52),9 points(17.2%) exeeded $5mg/m^3$- the time-weighed PEL-and one department had a upper confidence limit(95%) higher than $5mg/m^3$. 2) Dermatologists examined 213 workers. 172 of them complained any skin symptoms at that time - itching(32.5%), papule(21.6%), scale(15.7%), vesicle(12.5%) in order. The abnormal skin site found by dermatologist were palm(29.3%), finger & nail(24.6%), forearm(16.2%), back of hand(8.4%) in order. 3) As the result of physical examination, we found that 160 workers had skin diseases. Contact dermatitis was the most common; 69 workers had contact dermatitis alone(43.1%), 11 had contact dermatitis with acne(6.9%), 10 had contact dermatitis with folliculitis(6.3%), 1 had contact dermatitis with acne & folliculitis, and 1 had contact dermatitis with abnormal pigmentation. Others were folliculitis(9 workers, 5.6%), acne(8, 5.0%), folliculitis & acne (2, 1.2%), keratosis(1, 0.6%), abnormal pigmentation (1, 0.6%), and non-specific hand eczema (47, 29.3%). 4) The prevalence of any skin diseases was 34.0 pet 100 in cutting oil users, and 13.3 per 100 in non- users. Especially, the prevalence of contact dermatitis was 23.0 per 100 in cutting oil users and 23.0 per 100 in non-users. 5) We tried patch test(standard serise, oil serise, organic solvents) on 49 patients to differentiate allergic contact dermatitis from irritant contact dermatitis and found 20 were positive. 6) In a multivariate analysis(independant=age, tenure, kinds of cutting oil), the risk of skin diseases was higher in the water-based cutting oil user and both oil user than non-user or neat oil user(odds ratio were 2.16 and 2.78, respectively). And the risk of contact dermatitis was much higher at the same groups(odds ratio were 5.16 and 6.82, respectively).
