소프트 콘돼트렌즈의 재질파 보관용액에 의한 세포독성과 홉수 스펙트럼에 대한 홉광도를 비교하여 상호간에 관련이 있는지 여부를 조사하기 위해 본 연구롤 시행하 였다.7 개 제품의 각 제품별로 16 개 렌즈를 5ml의 증류수가 들어있는 병에 넣어 12 1 "C에서 1 시간 동안 용출하였다. 전에 연구한 배양세포 증식저해 시험에 대한 결과를 토대로 용출액과 보관용액에 대한 홉광도를 UV Spectrophotorne따를 이용하여 220- 350nm에서 측정하였다. 고함수 이온성 재질인 2 개 제품의 용출액과 보관용액의 홉 광도는 220-240nm에서 기준값보다 높게 나왔으나 241-350nm에서는 모두 훨씬 낮은 값올 나타내어 투명한 것으로 판명되었다. 이러한 결과로 용출액과 보관용액의 세포독성과 홉광도와는 거의 관련이 없는 것으로 판단된다.

Total carotenoid contents, color values and spectrum characterization in the range of UV of fruit juice and organic acid and free sugar contents determined by HPLC were investigated on 10 varieties of Cheju citrus fruits. Carotenoid contents of juice were 0.47-9.20/ml which showed higher with Dangyooja while showed lowest content with Meiwa Kumquat. Lightness (L) of juice was highest in Meiwa Kumquat, and in the order of Sankyool, Navel orange and Hungjin. Redness(a) and yellowness(b) were in the order of Dangyooja, Natsudaidai, Sambokam and Kinkoji. The maximum absorption wavelengths if citrus Juices were variable at 269.5-285.5nm according to varieties and it was observed that were changed by mixing with Juices of other varieties. Major organic acids of citrus juice were citric and malic acid, and citric acid was 64.4-95.1% of total organic acids. Ascorbic acid was high in Navel orange, Sudachi and Dangyooja, and low in Meiwa Kumquat and Hungjin. Major free sugars were sucrose, glucose and fructose. Sucrose was 49.2-75.2% of total free sugars, and high in Sankyool and Meiwa Kumquat. Glucose and fructose were high in Meiwa Kumquat and Navel Orange.
