Abstract:
Recently, people living in a rapidly industrializing country such as Korea seems to have less opportunity to be exposed to Rhus and Ginkgo trees than before, which may cause a lower prevalence of sensitivity to such allergens than those reported in the past. To prove the prevalence of sensitivity in Koreans, we have tested 0. 002g and 0.0l%, Urushiols and 10% Ginkgo leaves produced by Torii company to 72 atients with or suggesting contact dermatitis. The results were as follows: 1) Twelve of 72 patients(13, 9%) showed positive reactions and two patients(2. 8 %) showed active sensitization to both 0. 002% and 0. 0l% Urushiols. Only one patient(]. 4%) reacted to 10g Ginkgo leaves, and she was also reacted to the Urushiols. 2) Age and sex distribution of the positive reactors were none under thirty, 2 in thirties, 3 in forties, 4 in fifties, one over sixty, and seven female patients outnumber three male patients. 3) Out of 5 patients having past history cf contact dermatitis to Rhus tree, only patients showed positive reactions. Out of 67 patients without past history of allergy to Rhus, 8(ll, 9%) showed positive reactions and 59(88. 1%) showed negative reactions.
