We report three cases of rat mite dermatitis caused by Ornithonysus bacoti(Hirst, 1913), commonly referred to it as the tropicalrat mite. The first case, a 26-year old female had multiple pinhead sized vesicles with peripheral erythematous macule on the upper arms. The second case, a 34-year-old femal had multiple variable sized vesicles with erythematous base on the extremeties. The third case, a 43-year old male had multiple erythematous macules and papules with central punctum on the trunl: and extremities. Histopathologic sections from lesions of the first and second patient showed moderate perivascular lymphahistiocytic infiltration intermingled with some eosinophils. Causative mites, Ornithonyssus bacoti, female were collected around the skin lesion in rase 1, from the house dust in case 2 and furniture in case 3.

The ABO blood type was discovered by Karl Landsteiner in 1901. The frequency of occurrence of the ABO blood type in Korea was reported in the journal of the Joseon Medical Association in 1922. The status of 54 transfusions at one medical clinic in 1924 was reported at a medical congress in 1925. Many direct transfusion cases in Korea were identified by a literature search for articles published during the 1920s.

The certificate of blood donation was introduced in 1975. Blood donor receives the certificate after donation. The person who has this certificate can receive one unit of blood component transfusion without charge in the hospital when he needs transfusion. The donor can use it for himself or anyone else whom it may concern, if necessary. This blood pre-deposit system in Korea is regulated by Transfusion Law. The government health insurance budget and pre-deposit foundation budget support the reimbursement fee for blood. Whenever blood centers collect blood from donors, they deposit 2,500 KRW into the pre-deposit foundation budget. The return rate of certificates was 15-28% and recently showed a gradual decrease to 13% due to the extension of coverage by government insurance for cancer patients, who are the main transfusion candidates. This system has contributed to the shift from paid donation to voluntary donation for the past 40 years. However, because this certificate imposes financial incentives for donors, the spirit of voluntary non-remunerated donation can be abused. If the transfusion fee is fully covered by government budget, it might be possible to discontinue the use of the certificate in order to implement true voluntary donation.
