A nationwide survey was performed to know the geographical distribution of Gymnophalloides seoi (Digenea: Gymnophallidae) metacercariae in Korea, by examining the infection status of locally produced oysters, Crassosden gillu. A total of 24 coastal areas (myons) of 14 guns (=counties) in Kyonggi-do, Chollabuk-do, Chollanam-do, Kyongsangnam-do, Kyongsangbuk-do, or Kangwon-do, where natural oysters are produced but G. seoi has never been reported, and 13 areas (myons) of Shinan-gun, Chollanam-do, nearby the known endemic area, were surveyed. Oysters from non- endemic areas were free from G. seoi infection, except Byonsan-myon of Buan-gun, Chollabuk-do, where one of 50 oysters examined was infected with 15 metacercariae of G. seoi. In Shinan-gun, oysters from 10 areas including Aphae-myon (= township) and Anjwa-myon were infected with the metacercariae, with the infection rate ranging from 1.7% to 100% by areas. The intensity of infection was the highest in Aphae-myon, 785.9 metacercariae per oyster. The results indicate that high prevalence of G. seoi is confined to Shinan-gun, but low grade prevalence is also present in adjacent areas such as Buan- gun, Chollabuk-do.

To develope wild flower collected from Chollabuk-do area resource plant species were investigated from May 1996 to April 1997. This study was focussed to make the basic data for better quality of breeding species from wild flower species and to keep proper gene pool for development with competitive power internationally in future. There was 131 species blooming in spring season(34.7%), 219 species in summer(58.1%), 25 species in autumn(6.6%) and 2 species in winter(0.5%), respectively. Flower color of all the plants was 26 kinds in diverse, among them, white flowers were occupied dominantly of 28.9%, yellow flowers, 20.7%, violet flowers, 16.4% and red purple flowers, 7.9%, respectively. Transplanted wild flower plants at the garden in the study area frequently were Chelidonium majus var. asiaticum, Hemerocallis fulva, Iris nertschinskia, Rhododendron yedoense var. poukhanense, Rhododendron mucronulatum, Pulsatilla koreana, Chrysanthemum zawadskii var. latilobum, Taraxacum platycarpum, Chrysanthemum boreale, Liriope platyphylla and Lycoris radiata. Twenty-six species of wild flowers such as Cymbidium goeringii, H. fulva, L. radiata, C. zawadskii var. latilobum, etc. were collected from their habitat and being selling at the market or road side. Total 343 taxa of wild flowers to prevent carrying out to foreign countries and to improve better quality were selected and recommended in this study, for example, they were 41 taxa of Compositae plant, 25 of Rosaceae, 20 of Liliaceae and 18 of Ranunculaceae in order. Acorus calamus var. angustatus, Cypripedium japonicum, C. macranthum, Calanthe discolor, Dicentra spectabilis, Ilex cornuta, Stewartia koreana, Abeliophyllum distichum, Forsythia saxatilis and Campanula glomerata var. dahurica should be protected as wild flowers because their numbers are decreasing remarkably, belong to rare species, being at a crisis to extinct species and important plants for research materials.

For a general ingredients analysis and E Coli-form bacteria surveyed on the marketed milk, samples of bottled milk produced by four different companies were collected in Cholla Buk-do area and examined. The results are: 1) In water content samples A and C exceeded the standard slightly whereas B and D were good. 2) The contents of crude fat and crude protein of all samples were slightly higher than the standard. 3) All samples were deficient in contents of the crude ash and lactose. 4) In spite of the winter, all samples contained more coli-form bacteria than the standard allowance. Through the above results, it could be seen that all samples of marketed milk were a little poor in the contents of general ingredients and contained more coli-form bacteria than the standard allowances. Therefore, considering the general trends of increasing milk consumption and its influence on the national public health. it is necessary for the milk manufacturer to try to streng hen the scientific inspection and improve, the handling of milk products during the distribution.
