복분자씨유의 식용유지 대체가 C57BL/6J Mice의 혈청 지질에 미치는 영향

국문 초록 (Abstract)

본 연구는 식이로 비만이 유도되는 C57BL/6J mice에 복분자씨유와 지방의 종류를 달리한 식이를 급여하여 체중 및 체내 지질패턴에 미치는 효과를 평가하고자 수행되었다. 이를 위해 실험동물의 체중증가량 및 식이섭취효율을 평가하고, 지방 조직의 무게 및 혈중과 간 중 지질성분을 분석하였다. 또한 β-oxidation과 관련된 카르니틴 함량 변화와 superoxide dismutase(SOD) 항산화효소 활성도를 측정하였다. 실험 결과 실험동물의 체중이 고지방복분자씨유첨가식이군(RCO군)에서 유의하게 감소하였고, 식이섭취효율이 고지방옥수수유첨가식이군(CO군)과 RCO군에서 유의적으로 낮았다. 복부 지방과 등 지방은 CO군과 RCO군에서 유의적으로 낮았고, 혈중 HDL-C와 HDL-C/TC(%)는 RCO군에서 유의적으로 높았다. 간 중 acid-soluble acylcarnitine 및 total carnitine의 카르니틴 수준은 CO군과 RCO군에서, SOD 항산화효소 활성은 RCO군에서 고지방돈지첨가식이군과 고지방우지첨가식이군에 비해 유의적으로 높았다. 본 연구 결과 복분자씨유는 비만이 유도된 성인 쥐의 체중 및 체지방량과 HDL-C 및 HDL-C/TC(%)의 개선에 긍정적인 영향을 미치는 것으로 분석되었으며, 이는 복분자씨유를 비만인들에게 적용했을 때 매우 효과적인 유지 급원으로써의 사용 가능성이 있음을 시사하는 결과로 사료된다. 이에 대해 추후 복분자씨유의 기능성과 상업성에 대한 후속 연구가 필요할 것으로 여겨지며, 본 연구는 현재 식품가공 과정 중 폐기처분되고 있는 복분자씨가 식품산업의 새로운 소재로써의 가능성이 있음을 확인한 의미 있는 실험이라 사료된다.

This study evaluated the effects of Rubus coreanus Miq. oil on the plasma lipid profile of high fat diet (HFD)-induced obese mice. Animals were randomly divided into 4 groups (n=10). After completion of the 5-week experimental period, we measured bodyweight gain, food intake, adipose tissue mass, and plasma lipid profile. We also analyzed the activities of carnitine and superoxide dismutase (SOD) involved in β-oxidation and antioxidation, respectively. Our results show that HFD-induced weight gain in animals in the R. coreanus Miq. oil diet group (RCO) and corn oil diet group (CO) was significantly lower compared to animals in the HFD group; RCO supplementation had a more noticeable effect than CO. Visceral and back fat weights were lower in the RCO and CO groups while plasma HDL cholesterol (HDL-C) and HDL-C per total cholesterol [HDL-C/TC (%)] ratio were significantly higher in the RCO group. The contents of acid-soluble acylcarnitine and total carnitine as well as SOD activation were significantly higher in the RCO group, but no significant difference was observed between the RCO and CO groups. In conclusion, RCO effectively averted elevation of total body weight and fat weight in HFD-induced obese mice and promoted increased HDL-C. Therefore, R. coreanus Miq. oil might play an anti-obesity role in obese people and could be used as an effective oil supplement.
