Abstract

This study was conducted to examine the effects of Opuntia ficus-indica complexes(OCB) on the intake of water and food, body weight, blood glucose levels, glucose tolerance and lipid metabolism in streptozotocin(STZ)-induced diabetic rats. Thirty-two male Sprague-Dawley rats were assigned to four different groups; non-diabetic control(NC), diabetic control (DC), diabetic OCB of 2%(OCB-2), and diabetic OCB of 5%(OCB-5). The animals were fed on each experimental diet for 3 weeks. The DC, OCB-2 and OCB-5 groups showed a higher intake of water and food than the NC group. The fasting blood glucose levels were 100 $ mg/d{\ell}$ and 416 $ mg/d{\ell}$ for the NC and DC groups, respectively. The OCB-5 group presented a significantly low fasting glucose level of 21%(P<0.05), while OCB-2 group had a decrease of 13% compared to the DC group. As for the results of the glucose tolerance test, the highest blood glucose level was observed for all the groups at 30 minutes after the glucose injections as well as higher plasma insulin levels in the OCB-5 group. Plasma total cholesterol, triglyceride, non-esterified fatty acids(NEFA) and LDL-cholesterol concentrations were also lower in the OCB-2 and OCB-5 groups. The experimental diet did not affect the HDL-cholesterol levels. The overall results suggest that the higher intake of food by the OCB-2 and OCB-5 groups improved the blood glucose levels and lipid metabolism in STZ-induced diabetic rats.

손바닥선인장 복합물(OCB)의 항당뇨 효과 및 기작을 알아보기 위한 연구의 일환으로, OCB의 급여가 STZ으로 당뇨가 유발된 8주령 수컷 흰쥐의 음수량, 식이 섭취량, 체중, 공복혈당, 당내성에 미치는 효과와 당뇨의 합병증인 고지혈증(중성지방, 유리 지방산, 총 콜레스테롤, LDL-콜레스테롤, VLDL-콜레스테롤, HDL-콜레스테롤)의 개선효과를 조사하였다. OCB는 손바닥선인장의 줄기, 여주, 천화분, 목단피, 산약, 강황과 호로파를 조합하여 제조하였고, 기본사료에 2%와 5%의 수준으로 첨가하여 8주령 rat 수컷에게 3주간 자유 채식시켰다. OCB의 수분함량 약 12%, 조회분 15.4%, 조지방 1.26%, 조단백질 4.9%, 조섬유량 6.3% 및 탄수화물 함량은 60% 이상으로 주성분은 탄수화물이었다. 체중은 NC에 비해 DC, OCB-2와 OCB-5에서 감소하였다. 음수량과 사료섭취량은 NC에 비해 DC가 각각 약 8배 및 1. 5배 이상 증가하였고, OCB-2와 OCB-5는 DC와 비교해 유의적 차이가 없었다. NC의 공복 혈당은 평균 100 $mg/d{\ell}$, DC는 416 $mg/d{\ell}$이었으며, OCB-2는 362 $mg/d{\ell}$, 그리고 OCB-5는 329 $mg/d{\ell}$로 혈당농도의 감소를 보였다. 당내성 실험에서 모든 실험군은 포도당을 급여한지 30분 후에 최고 혈당을 나타냈고, OCB-5는 유의적인 감소를 보였다(p<0.05). 혈장 인슐린 함량도 DC와 비교해 NC, OCB-2, 그리고 OCB-5에서 유의적인 증가를 보였다(p<0.05). 이상의 결과에서 OCB의 급여는 STZ으로 당뇨가 유발된 쥐에서 당뇨의 개선효과가 있는 것으로 판단된다. 또한, OCB의 급여는 당뇨의 합병증인 지질대사에서 혈장의 중성지방, 유리지방산, 총콜레스테롤, LDL-콜레스테롤 그리고 VLDL-콜레스테롤을 모두 DC와 비교해 유의적인 수준으로 감소시켰다(p<0.05). 이러한 결과에서 볼 때, OCB의 급여는 당뇨의 합병증인 지질대사의 이상도 개선하는 것으로 관찰되었다.
