어유섭취가 출생후 발달과정의 흰 쥐의 간과 뇌조직의 지질과산화와 그 관련기능에 미치는 영향
Effect of Dietary Fish Oil on Lipid Peroxidation in Rats Liver and Brain During Postnatal Development
초록
어유를 섭취하였을 때, 체내 과산화물 생성과 항산화 기능을 조사하며, 그 결과를 다른 식이지방과 비교하기 위하여, 고등어유, 대두유, 쇠기름, 들기름, 채종유의 5 종의 지방을 먹이의 10% 되게 식이를 조제하여 70g 내외의 암, 수컷의 흰쥐에게 섭취시켰다. 출생후 초기 성장시에 적응도를 관찰하기 위하여, 위의 쥐들을 34일간 조제식이로 사육한후, 교배시켜 출생한 2 대째 쥐들을 수유시기(17일, 26일)과 이유시기(39일)에 희생시키고, 출산, 수유를 마친 어미쥐(나이 123일, 총 식이일수 81일)를 희생하여 간과 뇌조직의 지질과산화물,
Lipie peroxide formation, antiperoxidative s system and body adaptability for handling lipid p peroxide were examined in the first and second g generations of rats fed fish oil. Mackerel oil(MO) was used and four other dietary oils and fat, i.e. soybean oil(SO), perilla oil(PO), rapeseed oil(RO) and beef tallow(BT) were also employed to compare the effect of fish oil. Synthetic diets containing these five dietary fats at the level of 1O%(w/w), were given to the correspondm ing groups of male and female rats weighing about 70 grams. After 34 days of feeding, male a and female rats were mated and their offsprings were raised throughout suckling (17, 26 days) and weanling (39 days) periods. Liver lipid perox xide level was highest in MO group of both first (mother rats after lactation) and second generat tions of 17 and 26 days old, but not of 39 days old. During suckling period, liver lipid peroxide level was well matched to total unsaturation of dietary fat. Brain lipid peroxide levels were not different among five groups. Liver
