  • Ginsenosides Rb1, Rb2, Rc, Rd, Re, Rf and Rg1 were effectively isolated from ginseng root by preparative liquid chromatography (LC) on two PrepPAK-500/c18 cartridges in series and semipreparative LC on a .mu. Bondapak cabohydrate analysis column, a .mu.Bondapak C18 column or a .mu. Porasil column. The identities of the isolated ginsenosides were confirmed by analytical high-performance liquid chromatography (HPLC) and infrared spectrophotometry. By this method large scale isolation of pure ginsenosides was efficiently accomplished.

  • The possibility that high, long-term intake of carbohydrates that are rapidly absorbed as glucose may increase the risk of type 2 diabetes has been long-standing controversy. A high consumption of carbohydrates with a high glycemic index produces greater insulin resistance than did the intake of low glycemic index carbohydrates. This study was designed to evaluate the cabohydrate intake status include glycemic index and correlation carbohydrtae intake status with anthropometry factors & other nutrients in usual diet of the Korean type 2 diabetes mellitus. In 104 tpye 2 diabetes mellitus patients(mean age : 51.8yr, male=44.femal=60), we determined carbohydrte intake status include glycemic index with 24hr recall method and measured anthropometry. Mean daily carbohydrtae intakes and glycemic index were 307.3g(male 323.1g, female 295.5g) and 90.7(male 93.4, female 88.8), respectively. We found a strong and statistically significant association between carbohydrate ratio and glycemic index in obese factors, other nutrient. But carbohydrate intake/kg of body weight was low a significant differences in obese factors, other nutrient. Also glycemic index was effected by total energy intake and carbohydrate ratio than carbohydrate intake/kg of body weight. In conclusion, emphasis for dietary modification should be total energy intake and carbohydrate ratio in diabetes mellitus patient.

  • Riboflavin status of 17 insulin-dependent diabetic mellitus(IDDM) patients in growing period was evaluated as a function of energy intake and expenditure, biochemical nutritional status and diabetic control indicators. Compared with recommended dietary allowances for Koreans(RDA, 1989), only 35.3% of subjects was at good levels of all nutrients intakes and 52.9% of subjects was below normal level of height and weight. Nutrients consumed below RDA levels were energy(=88.5% of subjects), niacin(64.7%), iron(52.9%) and protein(23.5%) respectively. The riboflavin status was within normal range by urinary riboflavin excretion but 17.6% of subjects was evaluated as showed riboflavin deficiency by erythrocyte glutathione reductase activity coefficient(EGRAC). Correlation between riboflavin intake, urinary riboflavin excretion, EGRA level and diabetic duration were not statistically significant. Correlation analyses indicated that EGRA level was inversely correlated with thiamin, niacin and cabohydrate intake. No significant correlations were found between the EGRA and glycosylated hemoglobin A1(HbA1) (r=-0.464, p=0.129). From this study, it is suggested that IDDM subjects need to maintain balanced diet containing nutrients above RDA for individual activity during growing period. It needs more study whether the current recommended riboflavin allowance is adequate for diabetic patients.

  • Microstructure of abaxial leaf surface and carbohydrate content of propagules grown in different culture conditions such as heterotrophic, mixotrophic and autotrophic carbon source were investigated. In the leaves of propagules which were grown in the green house, autotrophic and mixotrophic conditions, wax layer was observed, but in the leaves of the heterotrophic propagules, it was not observed. Size and number of stomata of the leaves in the heterotrophic condition was larger and more numerous than that of autotrophic propagules. Especially, stomata of the leaves in the autotrophic condition was similar to the leaves of plant grown in green house. Carbohydrate content was higher in photoautotrophic condition than that in mixotrophic and heterotrophic culture. Also, Free sugar content showed higher in photoautotrophic propagules than that in mixotrophic and heterotrophic culture. In all the culture conditions, content of glucose were higher than that of other free sugars.

  • The effect of dietary vegetable oils on the growth and blood glucose level of rabbit was examed. This study was carried out to observe the nutritive effect of feeding vegetable oils for a period of weeks. The experimental diets were prepared on the basis of isocaloric and isonitrogenous diet. The Experimental animals were fed on 5 kinds of diets such as control (Basal), group A(Basal + sesame oil), group B(Basal + perilla oil), group C(Basal + soybean oil), and group D(Basal + rice bran on diets for 4 weeks. The results obtained are summarized as follows: 1. The gain in body weight of rabbit was higher for perilla oil fed group than any other group gained. 2. Liver weight of the control group, group A, group B, group C, and group D were 30.35 or 37.35 or, 37.25 or, 38.25 gr, 31.05 gr, and 39.54 gr, respectively. The reletionship between liver and body weight were 3.25, 3.99, 4.33, 4,15, and 4.57, respectively. It showed that to liver weight of group D which was fed rice bran oil was heavier than any other group showed. 3. The content of total protein and glucase level in serum of animal blood were 5.72 mg% 40.34 mg%, 5.65 mg%: 22.37 mg%, 5.95 mg%: 77.0 mg%. 5.62 mg%: 28.60 mg%, and 5.63 mg%: 34.10 mg%, respectively. As shown above, the group B was the most heaviest one. 4. It may be concluded from the above results that linolenic acid which was included in vegetable oils have an effect on interconversion among three caloric elements such as cabohydrate, protein, and fats.

  • The purpose of this study was to determine the effects of a pre-exercise meal on the plasma human growth hormone (hGH) response and fat oxidation during walking. Subjects (n=8) were randomly provided with either 1 g/kg body weight of glucose in 200 mL water (CHO) or 200 mL water alone (CON) 30 min prior to exercise and subsequently walked on a treadmill at 50% of VO2max for 60 min. Plasma hGH concentrations were significantly higher in subjects who received CHO compared to those who received CON at 15 and 30 min. The fat oxidation rate in the CHO was significantly lower than the CON while walking for 5~15, 25~35 and 45~55 min. Plasma FFA levels were also significantly lower in the CHO compared to the CON at 30, 45 and 60 min. Plasma glucose levels in the CHO were significantly lower while plasma insulin levels were significantly higher than in the CON at 15 and 30 min. Therefore, the results of this study suggest that the elevation of plasma hGH levels due to the intake of a pre-exercise meal may not be strongly related to fat oxidation and plasma free fatty acid (FFA) levels during low-intensity exercise.

  • The polysaccharide isolated from Phellinus species has been known as a folk remedy, including antitumor and immune-stimulating activities. However, there are lacks of knowledge about mycelial growth and exopolysaccharide (EH) production in its submerged culture. We investigated the optimal conditions on mycelial growth and EPS production in Phellinus baumii. The optimal temperature and initial pH for mycelial growth and EPS production in shake flask culture of P. baumii were proved to be 3$0^{\circ}C$ and pH 5.0, respectively. In case of carbon source, cellobiose and maltose were highly efficient for mycelial growth and fructose and mannitol were also relatively favorable for EPS production. Yeast extract was the most suitable nitrogen source for mycelial growth and EPS production. The composition of optimal culture medium was determined to be fructose 20 g/L, yeast extract 20 g/L, and $CaCl_2$ 0.55 g/L, respectively. Under the optimal culture condition, the maximum mycelial biomass and EPS achieved in a 5-L stirred-tank fermenter were 17.43 g/L and 3.6 g/L, respectively. It was found that the EPS was a glycoprotein onsisted of mainly arginine (14.1%) and glycine (12.0 %) in protein moiety and mainly mannose (48.7%) and arabinose (38.4%) in carbohydrate moiety.

  • This study was conducted to evaluate nutritional status with the analysis of the factors which might influence on the prevalent condition of nutrients-intake. 373 persons who are above 60 years old in Chung-Gu, Seoul were surveyed from March 15 to March 30 in 1985. Results were as follows ; 1. General Characteristics 1) Male respondents among the entire respondents comprised 54.3% and female respondents comprised 45.7%. As for age, male and female respondents comprised 55.0% and 37.2% respectively. 2) As for the educational level of the respondents, illiteracy was 49.9% which was the highest. and those who graduated elementary school was 28.1% which was the second highest. And as for the comparison of the education of the male and female respondents, the educational level of male respondents was much higher than that of female respondents. 3) As for the final occupation of the respondents, those who were engaged in commerce comprised 30.8% which was the highest rate, and who were engaged in agriculture comprised 20.1% which was the second highest rate. And those who were engaged in labor comprised 12.3%. 2. The State of Nutrients-intake The energy of the male respondents was 61.4% of RDA and the protein was nothing but 66.8% of RDA. Except vitamin A, vitamin $B_1$ and niacin, calcium, iron, vitamin $B_2$, vitamin C were lower than RDA (the range: $67.5%{\sim}97.3%$). The energy of the female respondents was 70.0% of RDA and the protein was 58.8% which were lower than RDA. Except vitamin A and vitamin $B_1$, calcium, iron, vitamin $B_2$ vitamin C, niacin were lower than RDA (the range: $68.2%{\sim}98.9%$). 3. The various factors related to nutrients-intake 1) The composition of family and the food environment those who were living with their spouses comprised 44.8% which was the highest rate, and those who were living with their son's family comprised 33.5% which was the second highest rate and those who were living with their doughter's family comprised only 4.6%. Those who were living alone comprised 16.4%. The correlation with nutrient intake didn't show a clear relation. 2) Socio-economic state Those who said that they lacked in living expense comprised 32.7% and those who said that they lacked in pocket-money comprised 23.9%, The female respondents outnumbered the male respondents in lacking living expense or pocket-money. In the correlation with socio-economic, there was no striking relation with education level. However, it was shown that little relation in energy, fat in male and also fat and iron in female. The living expense and the satisfaction in pocket-money had also little relation with energy fat and vitamin C in male. 3) Nutrition knowledge and food habit (a) The state of nutrition knowledge and food habit In nutrition knowledge, those who scored less than 60 points were 32.9%, and those who scored more than 90 points were 21.0%. In food habit, those who scored less than 60 points were 26.5% and those who scored more than 80 points were 45%. (b) The corelation with nutrition knowledge and food habit In case of female respondents, nutrition knowledge had a little relation with the intake of cabohydrate, iron, and vitamin C. And we couldn't see a distinct phenomenon in food habit.

  • Gestational diabetes mellitus (GDM) is defined as glucose intolerance discovered or onset during pregnancy and attention is needed because of increased risk of perinatal morbidties and higher incidence of diabetes afterward. This study was performed to identify dietary factors associated with the development of gestational diabetes mellitus (GDM). Developed food frequency questionnaire containing 192 food items were used to assess nutritional status of 246 control subjects and 104 GDM subjects. Food habits of subjects were examined in the questionnaire. The more irregularity and less variety of meal were found in GDM group compared to control group and GDM group tended to eat rapidly and do not like vegetables and greasy foods. Total score of food habits in GDM was lower than control group, which suggests that GDM group have undesirable food habits. Mean daily energy and carbohydrate intakes of GDM group were higher than those of control group, and percent energy from protein was significantly higher in control. Nutrient density of protein, calcium, phosphorus and vitamin BI of GDM group was significantly lower than those of control group. Therefore dietary quality of GDM group was lower than that of control group. Odds ratio for GDM was high when energy and carbohydrate intakes were high. And when the intakes of rice, noodle, shiruduk, hamburger, boiled egg, steamed pork shank were high, the odds ratio for GDM was high. These results indicate that the amount and frequencies of several foods and dish items were related with the occurrence of GDM subjects. On the whole, GDM subjects consumed more cereals and less vegetables and less legumes. From these results, pregnant women with GDM tended to have unhealthy food habits, and carbohydrate intake was important dietary factors on the onset of GDM.
