This study was done to investigate the antidiabetic and antioxidant effects of Lycii fructus in Streptozotocin (STZ)-induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose 45mg/kg.b.w. dissolved in citrate buffer(pH4.5). The ethanol extract of Lycii fructus was orally administrated once a day for 7 days. The contents of serum glucose, total cholesterol were significantly decreaed (p<0.05) in Lycii fructus treated group compared to the those of STZ-control group, also content of Triglyceride (TG), Altherogenic index (AI) were decreased, but not statistically significant. But high density lipoprotein (HDL)-cholesterol and HDL-cholesterol/total cholesterol ratio (HTR) were increased in Lycii fructus treated group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucose-6-phosphate dehydrogenase(G-6PDH), glutathione-s-transferase(GST), superoxide dismutase(SOD) were significantly increased(p<0.05), glucose-6-phos-phatase(G-6pase)was significantly decreased(p<0.05) and The glutathione(GSH), glucokinase(GK) were increased. But not statistically significant In Lycii fructus treated group compared to the those of STZ-control group These results indicated that ethanol extract of Lycii fructus would have antidiabetic and antioxidant effects in STZ-induced diabetic rats.

In order to investigate experimented effects of Indongdeung Jigolpi-Tang, which is applied to Soyangin, to diabetes, the measurement, comparison and observation made on the contents of volumes of blood glucose, total cholesterol, triglyceride, phospholipid, total protein and electrolyte($K^+$, $Na^+$) in blood serum by giving a high blood glucose, induced by streptozotocin, to hyperglycemic rats, dosing the cooked liquid of I.J.T., and following conclusion was attained. 1. The volume of glucose urine, induced by streptozotocin to hyperglycemic rats, was shown an increase in comparision to a normal flock when $12.50m{\ell}/kg$ of I.J.T. dosed to the rats and checked after two and four weeks and thereby, a sinificant reduction in the volume of blood glucose was made. 2. The volume of total cholesterol of blood serum in the diabetic rats, induced by streptozotocin, was increased in comparision to the normal flock, and in the fouth week of dosing $1.25m{\ell}/kg$ of I.J.T., a significant reduction of total cholesterol volum was shown in the blood serum. 3. The volume of triglyceride in the blood serum of the diabetic rats, induced by the streptozotocin, was increased in comparision to the normal flock, and with dosing $1.25m{\ell}/kg$ and $12.50m{\ell}/kg$ of I.J.T., a significant reduction of triglyceride volium was shwon in the blood serum after second and fourth week. 4. The volume of phospholipid in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparision to the normal flock, and with dosing $1.25m{\ell}/kg$ of I.J.T., a significant reduction of phospholipid volium in the blood serum was shown after first and second week. 5. The volume of total protein in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparison to the normal flock however, with dosing the I.J.T., no significant change on the volium of total protein was made in the blood serum. 6. The volume of potassium in the blood serum of the diabetic rats, induced by the streptozotocin, was increased in comparision to the normal flock however, with dosing the I.J.T., no significant change of potassium content was made in the blood serum. 7. The volume of sodium in the blood serum of the diabetic rats, induced by the streptozotocin, was somewhat reduced in comparision to the normal flock, and with dosing $12.50m{\ell}/kg$ of the I.J.T., a significant increase was shown in the blood serum after first week. Soyangin, accompanying with a middle and upper heat, the I.J.T. - that has a merits of cleaning up fever, solving fever, solving poison, solving thirst and restoring exhaustion - can be proved that it has a blood sugar reduction effect and it is considered that it can be meritorious for strengthening vitality, further, many other exhausting diseases, and can actively used for the cases such as thirst causing disease and a disease that causes an abnormal food hunger, thirst causing and frequent going to pass urine, in particular.

This research was planned and executed to evaluate how the composition of Yack-sun (oriental diet therapy) tea can effect the health conditions of people who are suffering from diet-related diseases such as being overweight, obese and hyperlipidemic, by taking Yack-sun tea in a form of nutritional supplement with daily meals. We produced Kangjieum with Lycense Mill., Polygonum multflorum Thunb, Cassia tora L., Crataegus pinnatifida Bge and Salvia miltiorrhiza Bge. We evaluated the effects of this tea on serum lipids, on homocysteine concentration, and on active oxygen contents, oxidative stress by clinical practices. We have determined that this tea has a significant effect on decreasing body fat content, decreasing total cholesterol, decreasing LDL-cholesterol, and decreses triglyceride and homocysteine concentrations. In addition, blood active oxygen content and oxidative stress were significantly decreased. We think that scientific and objective evaluation was performed on the components of Kangjieum prescription. We concluded that we could apply the components, not only in a form of tea, but also in other forms of various foods. The information we received from this conclusion will be basic information on how we can apply oriental medicinal resources into other food and will be a steppingstone for medicinal herbs to place a foot in the field of functional food research, which already draws sizable attention world-wide.

This study was performed to investigate the effect of rice bran dietary fiber powder on serum lipid levels, bowel function, and mineral absorption in rats. Four weeks old male Sprague Dawley rats(SD rat) were divided into four groups : control group fed 5% cellulose as a fiber source, RB10 fed 5% of cellulose and 10% of rice bran dietary fiber powder, RB20 and RB30. The animals were fed the experimental diets for 4 weeks. Serum lipid levels were not significantly different among the groups. But, fecal total cholesterol(TC), triglycerides(TG), and high density lipoprotein cholesterol(HDL-c) excretion increased in the RB30 group. Fecal weight and fecal water content were higher in the rice bran added groups than those in the control group. Transit time was significantly shorter in the rice bran fiber-added groups than that in the control. Weight of the stomach and large intestine in the RB20 and RB30 groups were significantly greater than those in the other groups. Absorption rates of Ca, Mg, P, and Zn decreased significantly in the RB30 group compared to those in the other groups. A high amount of rice bran increased fecal lipids, including TC, TG and HDL-c. Rice bran increased fecal weight and fecal water content and shortened gastrointestinal transit time. However, a high level of rice bran diet decreased mineral absorption rates.

An experiment was conducted to investigate the effects of supplemental copper (Cu) chelates (methionine, chitosan and yeast) on the performance, nutrient digestibility, serum IgG level, gizzard erosion, Cu content in the liver and excreta and the level of total cholesterol in breast muscle and serum of broiler chickens. Two hundred and forty hatched broiler chickens (Ross$^{(R)}$ 208) were assigned to 4 treatments: control, 100 ppm Cu in methionine chelate (Met-Cu), 100 ppm Cu in chitosan chelate (Chitosan-Cu) and 100 ppm Cu in yeast chelate (Yeast-Cu). Each treatment had six replicates of 10 (5 males+5 females) birds each. Weight gain and feed intake tended to be higher in Cu chelate treatments than the control; weight gain was significantly higher in the Met-Cu chelate treatment and feed intake was significantly higher in the Yeast-Cu chelate treatment than the control (p<0.05). Feed/gain was significantly different between treatments in which Met-Cu was lowest followed by the control, Chitosan-Cu and Yeast-Cu. DM availability was increased by Cu chelates among which chitosan-Cu showed the highest DM availability. Cu chelates supplementation tended to increase gizzard erosion index, and Cu content in the liver was highest in the Met-Cu treatment. Supplementation of Cu chelates tended to decrease total cholesterol level in breast muscle and serum but tended to increase the level of HDL in serum. It was concluded that dietary supplementation of 100 ppm Cu in chelates increased weight gain, feed intake and DM availability. Met-Cu was more effective than Chitosan-Cu or Yeast-Cu in improving productivity of broiler chickens.

This study was done to investigate whether cholic acid derivatives have anti-stress activity and what is a cause of this anti-stress effect. Seven cholic acid derivatives (cholic acid, taurocholic acid, ursodeoxycholic acid, tauroursodeoxychoic acid, chenodeoxy cholic acid, dehydrocholic acid, hyodeoxycholic acid) were used, silymarin and valproic acid were used as positive controls. Stress was induced by restraint immobilization technique plus water immersion (24hrs) and adrenal weight, spleen weight, adrenal ascorbic acid, serum cholesterol, lactate dehydrogenase (LDH), alkaline phosphatase (ALP), adrenal cholesterol, glucose and corticosterone levels were measured as stress indicators. Most cholic acid derivatives markedly decreased the adrenal weight, and TUDCA and DHCA increased the spleen weight. The restraint stress induced increments in serum LDH, ALP and cholesterol were attenuated by most cholic acid derivatives. Cholic acid, taurocholic acid and tauroursodeoxycholic acid only increased the content of adrenal ascorbate. While valproic acid showed an inhibitory effect against stress, silymarin did not. Our findings suggest that most cholic acid derivatives have anti-stress effect and that their anti-stress effect is, in part, related to choleretic activity.
