  • Antidiabetic activity and mechanism of Supungsungihyan(SPSGH) were examined in db/db mice, which is a spontaneously hyperglycemic, hyperinsulinemic and obese animal model. SPSGH and acarbose were administered orally for 4 weeks. Fasting and non-fasting serum glucose, glycated hemoglobin and trig-lyceride of SPSGH treated group were all reduced when compared with those of db/db control group. At 12th week after birth, SPSGH increased an insulin secretion although statistic significance was not seen. Total activities of sucrose, maltase and lactase in SPSGH treated group were not significantly different from those in db/db control. On the other hand, sucrase and maltase activities in acarbose treated groups were increased. Effect of SPSGH on mRNA expression of glucose transporter(GLUT-4) was also examined by RT-PCR and in vitro transcription with co-amplification of rat $\beta$-actin gene as an internal standard. Muscular GLUT-4 mRNA expression in SPSGH treated group was increased significantly. These results may suggest that SPSGH lowered blood glucose ascribing to upregulation of muscular GLUT-4 mRNA expression.

  • The stress of consecutive blood collectings resulted in evident elevation of plasma glucose level and significant lowering of chemiluminescent response of peripheral blood phagocytes in sea bass (Lateolabrax japonicus). Fish responded to the consecutive stressors in cumulative manners. The plasma glucose level in response to consecutive stressors depended on the stressor intervals. When the plasma glucose level of individual fish was compared with the chemiluminescent response, statistically significant (P<0.05) negative correlations existed.

  • This study aimed at the effect of carbohydrate level on serum glucose and lipid in Korean female 300 NIDDM patients. Mostly NIDDM appears in 50-64 years. As carbohydrate level increased, nutrient intakes increased. Most carbohydrate intakes were polysaccharides. High carbohydrate diets made blood glucose level increased. But high carbohydrate-fiber diets result lowering effect on serum LDL /HDL-cholesterol ratio and triacylglycerides. In conclusion, NIDDM patients need regular exercise and total energy intake balance. High carbohydrate-fiber diets are recommendable.

  • The biosynthesis of Lovastatin, a cholesterol lowering agent formed by the filamentous fungus, cerulenin-resistant Aspergillus terreus mutant was studied in shake flasks and bioreactors. The lovastatin production could be improved by fed-batch under the limited condition of carbon source. The relationship between the fungal morphology and the lovastatin production was also examined during the fed-batch cultures. The fed-batch studies in shake flasks were carried out to find the optimum glucose feeding method, and the pulsed feeding of glucose from 3 days onward at 24 hours intervals was found to be optimal to increase the lovastatin production and reduce the average pellet size. When the pH was controlled at around 5.8 during the whole fermentation period, the lovastatin concentration reached 384 mg/L, which is much higher than the values obtained pH-uncontrolled and pH 7.4. The optimal glucose feeding strategies was found that 30 g/L of glucose was added initially in batch mode, and then fed-batch was conducted by continuous addition of glucose solution(180 g/L) from 72 to 240 hr at a rate of 1.2 mL/hr at $28^{\circ}C$, pH 5.8, 400 rpm, and 1.0 vvm. The lovastatin concentration of 547 mg/L was obtained in 168 hr. It was about 1.5 times higher than the value of the batch fermentation.

  • A meta-analysis of 63 randomized controlled trials of Pioglitazone and Rosiglitazone in patients with type 2 diabetes was conducted. Pioglitazone significantly lowered fasting plasma glucose and triglyceride (TG) level and increased high-density lipoprotein cholesterol (HDL) level. Rosiglitazone significantly lowered hemoglobin A1C level and fasting plasma glucose, whereas it increased all kinds of lipids (HDL, LDL (low-density lipoprotein cholesterol), TG, total cholesterol). In comparison, glucose lowering effect was higher in Rosiglitazone, and Pioglitazone produced a more favorable lipid profile.

  • The purpose of this study is to investigate the effects of the ice-cream containing mulberry leaves on glucose levels in blood and on sensory characteristics. Mulberry leaves were treated with sodium hydrogencarbonate (NaHCO3) to remove the fresh green note out of dried mulberry powder with ball mill. The recovery rate of dried mulberry leaf powder was 28.9% from fresh mulberry leaves. The points of ice-cream with (treatment 2 : milk-fatty 23%) and without (treatment 7 : coconut butter 9.5%) milk-fatty in the sensory characteristics were 8.31 and 8.47, respectively, of 9.00 as a full point. The range of age of volunteers taken part in the glucose level test were 21∼25 years old. The glucose levels in blood were measured before and after taking up ice-cream. In case of ice-cream with vanilla, the glucose levels increased 27.8%, while those in the up take of ice-cream with mulberry powder decreased 1.6%. In conclusion, the present study has demonstrated that ice-cream containing mulberry leaf powder has an effect to decrease blood glucose levels after the application.

  • This study examined the effects of plums produced in Gimcheon area on the glucose and lipid metabolism in streptozotocin-induced diabetic rats. Male Sprague-Dawley diabetic rats were divided into four groups: control, diabetic control, Diabetes-low plum (containing 10% plum powder), and Diabetes-high plum (containing 20% plum powder). The animals were fed isocaloric experimental diets based on an AIN-76 diet for 6 weeks. Feed efficiency ratio (FER) of the diabetic groups were significantly lower than that of the control. On the other hand, among the diabetic groups, the FER of the high plum intake group was higher than that of the diabetic control. The liver weight per 100 g body weight of each group was similar but the liver weights tended to decrease as the amount of plum intake was increased. Kidney weight per 100 g body weight of the plum intake groups were significantly different compared to that of the diabetic control. The supplementation of plums lowered the fasting blood glucose level of the diabetic groups and improved the glucose tolerance, thereby lowering the glycosylated hemoglobin index. In addition, the supplementation of plum was lowered the blood total cholesterol concentration and increased the HDL-C/TC (%) significantly, thereby lowering the atherosclerotic index (AI) and hepatic peroxide level. A steady diet of plums produced in Gimcheon may be effective in controlling the blood glucose level and preventing chronic diabetes mellitus.

  • Rice(Oryza stiva L.) is a major cereal food providing nourishment to over half of the world's populations and was considered only as a source of energy. However, The recent many researches have been made to suggest that rice may relate to prevention chronic disease and health-promoting properties such as postprandial glucose response, hypocholesterolemic effect and blood pressure-lowering effect. There has been numerous observation supporting that rice has hypocholesterolemic effect. Rice, rice bran, rice bran oil and unsaponifiable matter of rice bran oil reduced plasma cholesterol in rat, hamster as well as human. Components of rice showing hypocholesterolemic effect include dietary fiber(hemicellulose, phytic acid). protein, ${\gamma}$-oryzanol, $\beta$-sitosterol, and tocotrienols. Crapo et al has been studied that the effect of various of starchy foods on the postprandial blood glucose and insulin responses in healthy and diabetic humans. The results showed that rice had lower blood glucose and insulin responses compared to potato, bread and dextrose. The different physical forms in the same starch also produce the different postprandial glucose and insulin responses. In recent years, several studies have shown that some components of rice have potent antioxidant activity against Fe$^{2+}$ -ascorbate induced lipid peroxidation in rat liver microsomal membranes. Cell culture and animal studies have shown that some components of rice have inhibitory effect on the growth and proliferation of several types of human cancer cell. It was also reported that the methanol extract of brown rice has antimutagenic activity against various mutagens. In addition, the pepsine hydrolysate from rice protein is reported to inhibit angiotensin converting enzyme activity. GABA (${\gamma}$ - aminobutyric acid) and GABA enriched rice germ is also effective for lowering blood pressure and triglyceride levels.s.
