By light and scanning electron microscopy, the morphologies of Korean pubic louse(Phthirus pubis) were described and measured. Especially, electron microscopic structures of palpus, tuft organ, sensilla basiconicum and palpal lobe were reviewed in detail. The variations were obserbed in the number of dorsal setae and the setae of membranous processes of abdomen. And also, the importance of public health and epidemiological aspects was discussed.

BACKGROUND: Otitis media with effusion(OME) is a very common disease in pediatric age. However, a few literatures on epidemiologic study of otitis media with effusion are available in Korea due to the great variability of its diagnostic criteria and clinical features. The aim of this study is to provide the estimate of silent otitis media prevalence for preschool age. METHODS: The study population includes 329 children enrolled in 6 kindergartens in Kunsan city from April 1 to 10, 1995. Silent otitis media was diagnosed with otoscopy, pneumatic otoscopy and impedance audiometry by DANAC 40 model impedance audiometer from DANA JAPAN Co. RESULTS: The prevalence of silent otitis media with effusion was 14.5% and peak at 6 years of age(17.8%).The prevalence of silent otitis media with effusion according to sex were 11.8% in boys group, 17.9% in girls group. Nine cases(11.8%) involved bilaterally. Forty three cases(89.6 %) were asymptomatic cases. CONCLUSIONS: Among 329 preschool children, the prevalence of silent otitis media with effusion was 14.5%. The prevalence by sex showed slightly higher in girls group than boys group. OME involved unilateral site mostly and subjective symptoms were rare.

BACKGROUND: To prevent the platelet refractoriness, repeated plateletpheresis is often required in HLA matched single-donors. Korean Transfusion Standard permits the repeated plateletpheresis of a single donor at 72-hour intervals. To evaluate this standard, hematological responses of donors were assessed after plateletpheresis by Haemonetics V50 (Haemonetics Co., USA). METHODS: The pre- and post-donated hematological indices of 22 healthy donors(17 males and 5 females) were evaluated. Single donated donors were 12 males and 4 females. Multiple donated donors were 5 males and one female. Post-donated platelet counts were measured immediately, 6 hours, 12 hours, 1 day, 3 days, 5 days, 7 days and 9 days after plateletpheresis. Platelet aggregation test, serum protein, PT, and aPTT were also examined before and after platelet collection. RESULTS: Only 9 (56.2%) of 16 single-donated donors and 4 (66.7%) of 6 multiple donated donors showed normal restoration up to 97% of platelet counts of pre-donation levels at the day 3. In 9 (75%) of 12 single donated males restoration of platelet count was observed within 3 days, but 3 (75%) of 4 single donated females showed restoration of platelet count within 5 days. Changes of other indices were not significantly different between the pre- and post-donations of platelet. CONCLUSIONS: Although no clinical complication was noted after plateletpheresis, these data suggested that Korean Transfusion Standard on plateletpheresis should be reconsidered.
