曺準承,蔣貞仙,洪大一 대구보건대학 1977 대구보건대학 論文集 Vol.3 No.-

韓國人 兒童(6才∼11才)의 血淸鐵, 不飽和鐵結合(UIBC) 및 總鐵結合能(TIBC)의 正常値를 調査하기 위하여 男兒34名과 女兒 34名을 對象으로하여 檢査한 結果는 다음과 같았다. 血淸鐵 : 男兒 135±30 (74-196)㎍/100㎖ 女兒115±34 (47-183)㎍/100㎖ UIBC 男兒 237±41 (155-319)㎍/100㎖ 女兒 225±46 (133±317)㎍/100㎖ TIBC : 男兒 366±32 (302-430)㎍/100㎖ 女兒 330±41 (248-412)㎍/100㎖ %Saturation : 男兒 37.1±8.0(21-53)% 女兒 34.6±11.9(21-59)% 以上의 値들은 成人의 그것과 比較해서 別 差異가 없었다. 그리고 大體的으로 女兒의 값이 男兒의 그것 보다 떨어지는 結果로 보였다. This paper has been caried out to determine the normal values for serum iron and iron binding capacity of Korean children, and to compare with that of adult men Non-festing blood specimens were collected from 34 males and 34 females in the morning (am. 9-10). Serum iron was estimated by the modified method of Barkan-Walker's, and the total iron binding capacity by Ramsay method. The results obtained were as follows: Serum iron: male 135-30ug 100ml (range; 74-196) female 115-34ug 100ml (range; 47-183) U.I.B.C. : male 237-41ug 100ml (range; 155-319) female 225-46ug 100ml (range; 133-317) T.I.B.C. : male 366-32ug 100ml (range; 302-412) female 330-41ug 100ml (range; 248-412) % Saturation:male 37.1-8.0% (range;21-53) gemale 34.6-11.9%(range;21-59) These normal values of children were no significant difference between that of adults which are reported by other investigators.

Macromolecular collagen components in rat liver at different stage of fibrosis induced by common bile duct ligation were studied. Animals were killed on the 3rd, 7th, 14th, 21st and 29th day after bile duct ligation and liver specimens and blood samples were obtained. Hepatic collagen was fractionated into neutral salt soluble, acid soluble, pepsin soluble and insoluble fractions, and hydroxyproline content of each fraction was determined. The collagen content, especially in insoluble fraction, was increased as the duration of biliary obstruction increased. Pepsin solubilized collagens were subjected to determination of the collagen types by SDS-polyacrylamide disc gel electrophoresis. The ratio of type I to type III collagen was decreased gradually with progression of fibrosis. These results indicate that an alteration in tissue collagen polymorphism as well as variations in the collagen solubility accompany the fibrotic process, suggesting possible pathogenetic implication.

肝Glycogen 生成에의 放射性 Glucose 및 아미노酸의 利用에 대한 食餌의 영향

曺準承,朴東烈 慶北大學校 1980 論文集 Vol.29 No.-

The rate of utilization of glucose or amino acids for liver glycogen synthesis was investigated in fed or 24-hour fasted albino rats weighing approximately 200g. Rats were administered intraperitoneally in a single dose of 4μCi of glucose-(U)-^14C with 100mg of glucose or amino acid mixture-^14C with 20mg of L-alanine per 100g body weight. Three hours later, the rats were sacrificed and the liver was analyzed for the determinations of glycogen content and activity of labeled carbon incorporated into the glycogen. The content of liver glycogen decreased from 1.2% of wet weight in the 24-hour fasted rats and remained low in the 72-hour fasted rats. In the fasted group, incorpration rate of glucose-(U)-^14C or amino acid mixture^-14C into liver glycogen was increased 2-or 4-fold, respectively, in compared with that of the fed group. And in the fasting state the incorporation rate of amino acid into liver glycogen was two-times higher than that of glucose. This result indicates that fasting stimulates glycogen synthesis in the liver from glucose and amino acids administered, and amino acid is to be more utilizable for the synthesis than glucose in the fasting state.

Cultivated dry ginseng root was pulverized and extracted with methanol. Theextractive was washed with ether three times and filtered. The filtrate was concentrated under reduced pressure and lipophilized to be dried. Sprague-Dawley rats weighing 200∼2208 were divided into the ginseng and the saline administered groups. The ginseng group were received daily 5㎎ per 1008 body weight of the ginseng extract in 0.5㎖ of saline peritoneally for 4 days, and the saline group received the same amount of saline. The ginseng and saline groups were further divided into the fasted group, maintained in fasting state for 24 hours before the last administration of ginseng, and the fed group, which was kept in feeding during the experiment. A hour later the administration of ginseng or saline to the corresponding, 4 μc of glucose-^(14)C with carrier 100㎎ glucose per 1008 of body weight or 4 μc of amino acid mixed-^(14)C with carrier 20㎎ L-alanine per 1008 of body weight were injected peritoneally for the correspond group and control.. Three hours after the administration of glucose or amino acid rats were killed to be determined the content of liver glycogen and phosphoenolpyuvate carboxykinase. To estimate the oxidation rate of glucose, rats were put in a metabolic cage immediately alter the injection of glucose. The expired carbon dioxide was collected into barium hydroxide solution and the radioactivity was counter by gas flow counter. It was revealed that the ginseng root extract increased the oxidation of glucose in rat in the early period of the time after a glucose injection. This effect was more prominent in the fasting state. Ginseng, however, does not so much effect on glycogensis and glyconeogenesis when the animal was at the state of feeding or fasting since glycogen content and the rate of glycogen synthesis from glucose-^(14)C or amino acid mixed-^(14)C in ginseng administered groups showed no fructuation compared with that of the control. Activity of phosphoenolpyruvate carboxykinase considered as a regulatory enzyme for glyconeogenesis was not changed by the administration of ginseng both the time of feeding and fasting.

인삼 성분이 당질의 산화 및 생성에 미치는 효능

인삼 성분을 메탄올로써 추출하고 이것이 쥐에 있어서 당질의 산화와 당의 생성 즉 glycogenesis 및 glyconeogenesis 그리고 당 신생반응의 첫 단계 반응을 조절하는 효소라고 믿고 있는 간의 phosphoenolpyruvate carboxylkinase의 활성에 어떠한 영향을 미칠것인가를 조사하여 보았다. 인삼 추출물을 쥐 체중 100g당 5mg이 되도록 생리적 식염수 0.5ml에 녹여서 1일 1회 4일간 복강내로 미리 투여하였으며 대조군에는 같은 양의 식염수만 주입하였다. 이것을 다시 계속 섭식시킨 군과 24시간 굶긴 군으로 나누어서 인삼 추출물을 투여한 1시간뒤에 glucose-$^{14}C$ 또는 amino acid mixed-$^{14}C$를 주입하여 호기중애 배출되는 $^{14}CO_2$ 양을 검출하고 또 3시간 후에 간속의 glycogen과 phospho-enolpyruvate caboxykinase에 대해서 검토하였다. 이 실험 결과 인삼은 glucose의 산화를 현저히 증가시켰으며 이 효과는 기아상태에서 더욱 촉진적으로 작용하였다. 그러나 인삼은 간에서의 glycogenesis나 glyconeogenesis에 대해서는 효능이 그리 없는것 같았다. 즉 인삼투여군은 대조군에 비하여 간의 glycogen농도나 $^{14}C$ 화합물의 glycogen에의 편입속도가 다같이 별 차이를 나타내지 않았다. 그리고 간의 phosphoenolpyruvate carboxykinase의 활성에도 인삼의 별 영향을 미치지 않았다.
