  • The enhancement of the human body fat reduction of conjugated linoleic acid (CLA) with the supplementation of $\gamma$-oryzanol (OZ) was investigated on overweight Korean women (n=51, BMI> 23). Subjects were divided into 4 groups of control, CLA, glyceride form of CLA (GCLA), and CLA plus OZ (CLA-OZ). The soft-gel capsule (500 mg) was used to deliver control (500 mg olive oil), CLA (500 mg CLA), GCLA (500 mg GCLA) and CLA-OZ (500 mg CLA plus 50 mg OZ). Three capsules were taken twice a day for 12 weeks. The CLA-OZ supplementation reduced 1.35% body fat that was 0.34% enhancement against CLA supplementation. As considered subject variations, CLA-OZ reduced body fat ranged from 7.9% to -2.7%, equivalent to 5.6 kg loss to 0.7 kg gain in body fat mass, against CLA. The CLA-OZ reduced body weight and body mass index (BMI), relative to control, but the reductions by CLA-OZ were not different from those by CLA and GCLA. All biochemical markers analyzed for safty were not significantly different within or between groups and were within the normal range. The CLA-OZ supplementation significantly reduced blood pressure, as compared to the supplementation of CLA, GCLA and control. These results suggest that OZ could be a useful ingredient to mix with CLA for the reduction of human body fat.

  • Conjugated linoleic acid (CLA)와 $\gamma$-oryzanol (OZ) 혼합물의 mouse 체지방 및 복부지방 감소에 관한 연구를 하였다. Female ICR mice (10주 령)을 몸무게 차이가 없도록 Control (70 ${\mu}l$ olive oil + 30 ${\mu}l$ CLA), CLA-OZ 1 (70 ${\mu}l$ olive oil + 30 ${\mu}l$ CLA + 0.5 mg OZ), CLA-OZ 2 (70 ${\mu}l$ olive oil + 30 ${\mu}l$ CLA + 1.0 mg OZ), OZ (100 ${\mu}l$ olive oil + 1.0 mg OZ) 및 Olive oil (100 ${\mu}l$ olive oil)로 구분하였다. 처리시료는 매일 4주간 경구투여 하였고 식이와 물은 자유롭게 먹게 하였다. 시료처리 4주 후에 mice의 몸무게를 달고 탈골법으로 sacrifice하여 전체몸무게, 복부지방 무게, 장기와 복부지방을 제거한 나머지 부분 무게 (empty carcass weight: ECW)를 측정하였다. CLA (control) 처리는 olive oil 처리에 비해 유의성 있게 몸무게, ECW, 복부지방 및 체지방을 감소시켜 CLA가 복부지방 및 체지방을 감소시킴을 알 수 있었다. CLA-OZ 1 처리는 OZ 처리에 비해서는 복부지방 및 체지방을 유의성 (p<0.05) 있게 감소시켰으나 CLA (control) 처리에 비해서는 유의성이 없었다. 또한 CLA-OZ 2 처리는 control 처리 및 OZ 처리에 비해 복부지방 및 체지방을 유의성 (p<0.05) 있게 감소시켰다. 이 결과는 CLA와 OZ를 혼합하여 처리한 mice에서 이들을 각각 단독으로 처리한 mice에서보다 복부지방 및 체지방이 많이 감소되어 OZ가 CLA의 지방감소 작용에 상승효과가 있음을 의미한다.
