김석영(Seok-Young Kim),차복경(Bok-Gyeong Cha) 한국식품영양과학회 1993 한국식품영양과학회지 Vol.22 No.2
본 연구는 자연스런 환경에 있는 다수인의 소비에너지를 측정하고자 할 때 보다 간편하면서도 정확하게 소비에너지를 측정할 수 있는 방법을 모색하고, 또 우리나라 여대생의 일일 소비에너지와 비만도에 다른소비에너지및 활동강도의 차이를 알아보고자 실시하였다. 여대생 82명을 대상으로 15-min check list와 calorie counter에 의한 두가지 방법으로 3일간의 소비에너지를 측정하여 두 방법에 의해 측정된 소비에너지의 관계를 검토하였는데 그 결과는 다음과 같다. 1) 일일의 소비에너지는 15-min check list에 의한 경우가 1963 kcal였고, calorie counter에 의한 경우가 1649kcal로 국내에서 보고된 타 연구결과와 비교해 볼 때 15-min check list에 의한 측정치는 비슷하였으나, calorie counter로 측정할 때에는 실제보다 낮게 측정되는 것으로 볼 수 있었다. 그러나 두 방법이 모두 신체 계측치와 상관성이 높았고, 또 두 방법사이에 상관도도 매우 높았으므로 calorie counter로 측정한 값을 ‘DEE by 15-min check list=3.31186+1.18837×DEE by calorie counter’의 식에 의해 15-min check list값으로 환산해 주면 다수인을 대상으로 측정할 때 보다 간편하면서도 정확하게 소비에너지를 측정해 줄 수 있을 것으로 생각된다. 2) 상대적 비만도에 따라 세군으로 나누었을 때 소비에너지와 활동강도가 세군에서 유의하게 달랐다. 또 자신의 활동을 15분 단위로 기록하게 한 뒤 활동등급별로 집계한 결과 활동등급 1의 빈도수가 저체중군이나 정상체중군에 비해 과체중군에서 유의하게 높았고 반면 활동등급 3의 경우에는 과체중군이 저체중군에 비해 유의하게 빈도수가 낮아서 과체중군이 덜 활동적이라고 볼 수 있었다. Daily energy expenditures (DEE) of 82 co-eds in a University were estimated simultaneously by use of calorie counter and 15-min check list diary for 3 days, including a weekend day. The results are summarized as follows. The mean values of DEE from 15-min check list diary and calorie counter were 1967kcal and 1649kcal, respectively. DEE obtained with 15-min check list diary seems to be consistent with the results made by others concerning DEE of college female in Korea, but DEE by calorie counter was lower than that. However, DEE by calorie counter show high correlations with anthropometric indices of subjects and DEE by 15-min check list diary. Therefore, DEE by 15-min check list diary was taken as standard and regression equation for predicting DEE of subjects were developed : DEE by 15-min check list diary = 3.31186+1.18837×DEE by calorie counter. This technique for measuring DEE permits us to have more accurate estimate of DEE and acceptable to the subjects. When the subjects classified as underweight, normal, overweight according to relative body weight(RBW), DEE and DEE per ㎏ of body weight were significantly different from each other between three groups based on RBW. The frequency of 15-minute periods with a categorical value of 1 was significantly higher in overweight than underweight and normal groups and the frequency of a categorical value 3 was significantly lower in overweight than underweight group. From the results shown above, physical activity level of overweight group was lower than that of normal and underweight groups.

Streptozotocin 유발 당뇨쥐의 신장 및 뇌조직에서의 Microsomal Mixed Function Oxidase System에 미치는 녹차 Catechin의 영향
이순재(Soon-Jae Rhee),신주영(Ju-Young Shin),차복경(Bok-Gyeong Cha) 한국식품영양과학회 1998 한국식품영양과학회지 Vol.27 No.2
당뇨 유발쥐에서의 신장 및 뇌조직에서의 MFO계 활성과 지질과산화에 미치는 녹차 catechin의 영향을 관찰하기 위해 체중 140g 내외의 Sprague-Dawley 숫쥐를 정상군과 당뇨군으로 나누고, 다시 식이내 catechin 함량에 따라 DM-0C(0% catechin), DM-0.5C(0.5% catechin), DM-1.0C(1.0% catechin) 식이군으로 나누어 4주간 사육한 후 정상군을 제외한 실험군을 STZ로 당뇨를 유발시켰다. 당뇨유발 6일 후 쥐를 희생시켜 신장 및 뇌조직 microsome 중의 mixed function oxidase(MFO) system과 과산화지질 함량을 관찰하였다. 신장 조직 중의 cytochrome P_(450) 함량은 정상군에 비해 DM-0C, DM-0.5C, DM-1.0C군에서 각각 77, 42, 49% 증가하였다. 한편 뇌조직 중의 cytochrome P_(450) 함량은 정상군에 비해 DM-0C군이 43% 증가하였으나, DM-0.5C, DM-1.0C군은 정상군과 비슷한 수준이었다. 신장조직 중의 cytochrome b_5 함량도 정상군에 비해 DM-0C군은 78% 증가하였고, DM-0C군에 비해 DM-05C, DM-1.0C군은 각각 38, 43% 감소하였다. 뇌조직 중의 cytochrome b_5 함량은 정상군과 비슷한 수준이었다. 신장조직 중의 NADPH-cytochrome P_(450) reductase는 DM-0C군이 정상군에 비해 27% 증가하였고, DM-0.5C, DM-1.0C군은 DM-0C군보다 13, 15% 감소하였다. 뇌조직중의 NADPH-cytochrome P_(450) reductase는 DM-0C군은 정상군에 비해 31% 증가하였고, catechin 투여군은 정상수준이었다. 신장 조직 중의 TBARS 함량은 정상군에 비해 DM-0C, DM-0.5C, DM-1.0C군에서 각각 147, 60, 59% 증가하였으며 뇌조직중의 지질과산화는 정상군과 당뇨군에서 비슷한 수준이었다. 따라서 녹차 catechin은 STZ 유발 당뇨군의 신장과 뇌조직에서의 MFO계 활성을 완화시키고, 지질과산화를 억제시킴을 알 수 있었다. The purpose of this study was to investigate the effect of green tea catechin on microsomal mixed function oxidase(MFO) system of kidney and brain in streptozotocin(STZ) induced diabetic rats. Sprague-Dawley male rats weighing 140±10g were randomly assigned to one control and three STZ-diabetic groups. Diabetic groups were classified to DM-0C(catechin 0%/㎏ diet), DM-0.5C(catechin 0.5%/㎏ diet), and DM-1.0C(catechin l%/㎏ diet) according to the level of catechin supplementation. Diabetes were experimentally induced by intravenous administration of 55㎎/㎏ body weight of STZ in citrate buffer(pH 4.3) after 4 weeks feeding of three experimental diets. Animals were sacrificed at the sixth day of diabetic state. The contents of cytochrome P_(450) in kidney were increased by 77, 42, 49% in DM-0C, DM-0.5C and DM-1.0C groups, respectively, than normal group. The contents of cytochrome P_(450) in brain were increased by 43% in DM-0C group than normal group, but those of DM-0.5C and DM-1.0C groups were similar to that of normal group. The contents of cytochrome b_5 in kidney were increased by 78, 38, 49% in DM-0C, DM-0.5C and DM-1.0C groups, respectively, than normal group. Meanwhile, the contents of cytochrome b_5 in brain were not significantly different among all groups. The activities of NADPH-cytochrome P_(450) reductase in kidney of DM-group were increased by 27% than normal group, but those of DM-0.5C and DM-1.0C groups were 13 and 15% lower than that of DM-0C group. The activities in brain were also increased by 31% in DM-0C group, but those of DM-0.5C and DM-1.0C groups were similar to that of normal group. Levels of TBARS(thiobarbituric acid reactive substance) in kidney were increased by 147, 60 and 59% in DM-0C, DM-0.5C, and DM-1.0C groups, respectively, compared with normal group, but those of DM-0.5C and DM-1.0C groups were 36, 35% lower than that of DM-0C group. Meanwhile, the levels of TBARS in brain were not significantly different among four groups. These results indicate that dietary catechins in green tea playa powerful antioxidant role in reducing the lipid peroxidation enhanced by activation of MFO system in STZ-induced diabetes.
