  • In this paper, the influences of adrenergic blockades; propranolol and phenoxybenzamine on the changes of hyperglycemic action, hepatic glycogen content, and brain norepinephrine (NE) content induced by clonidine were investigated in the male mice. The results obtained were summarized as follows: 1) Blood glucose level was significantly increased by clonidine $(30{\mu}g/kg)$. The increase of blood glucose level induced by clonidine was not affect by the propranolol (10mg/kg) pretreatment, but significantly inhibited by the phenoxybenzamine (10mg/kg) pretreatment. 2) Hepatic glycogen content was moderately inhibited by clonidine. The decrease of hepatic glycogen content induced by clonidine was not affected by the propranolol and phenoxybenzamine pretreatment. 3) Brain NE content was significantly increased in 30 minutes and 60 minutes after clonidine treatment. The increase of brain NE content induced by clonidine was significantly inhibited by the phenoxybenzamine pretreatment. The increase of train NE content induced in 90 minutes and 120 minutes after clonidine treatment was more markedly increased by the propranolol pretreatment.

  • Purpose: The purpose of this study was to evaluate whether the effect of the Internet diabetic education on plasma glucose in people with hyperglycemic diabetes. Method: A randomized design with control and experimental groups being assessed pre- and post-intervention was used. Twenty-two patients were randomly assigned to an intervention group and 21 to a control group. Participants were requested to input the blood glucose level weekly in http://www.biodang.com by cellular phone or wire Internet for 3 months. The researcher sends optimal recommendations to each patient using short message service(SMS) of cellular phone and wire Internet weekly. Results: Patients in the intervention group had a mean decrease of 1.3% in glycosylated haemoglobin ($HbA_1c$) levels and those in the control group had no significant difference. There was a significant mean change in 2-hour postprandial blood glucose(2HPPG) for the intervention group, with a mean change of-75.2mg/dl. The mean change in the control group was, however, not significant. Conclusion: These findings indicated that a web-based intervention using SMS of cellular phone improved $HbA_1c$ and 2HPPG.

  • Objectives : The aim of this study was to investigate the effect of Jaeumyangyung-tang(滋陰養榮場(JY), JA-0.65g/kg;JB-1.3g/kg) on hyperglycemic mice induced with streptozotocin(STZ). Methods : The experiment operated for 6 weeks. The rats were divided into 3 groups : diabetic group(control group), diabetic group treated with JA(0.65g/kg) for 6 weeks, and diabetic group treated with Jb(1.3g/kg) for 6 weeks. Results : In the STZ-induced diabetic group, blood glucose levels significantly increased as well as the loss of body weight. The levels of serum glucose decreased significantly (p<0.05 or p<0.01) in the JA and JB groups compared with the control. According to a tolerance test, intraperitoneal glucose was ameliorated in the JA and JB groups. The blood urea nitrogen (BUN) and creatinine levels slightly decreased. Histologic analyses of the pancreases revealed that the ${\beta}-cells$ on Langerhans' islets were destroyed by STZ, but the ${\beta}-cell$ mass was larger in the JY than in the control mice. Conclusions : These results indicate that JY can exert beneficial effects on diabetes. preservation of in vivo ${\beta}-cell$ function and regeneration of ${\beta}-cell$ dysfunction by STZ.

  • The experimental study have showed that the Polygonatum officinale All. contains diosgenin and ${\beta}-sitosterol$ as active components. Even though many experimental studies were reported, still there are many unknown actions of components from the plant. The purpose of this study was to elucidate the mechanism of hypoglycemic action of ether extract of Polygonatum officinale. The hypoglycemic effect of the ether extract was tested in hyperglycemic rats induced experimentally, The effect on plasma free fatty acid and the acute toxicity were also examined by using mouse. The hypoglycemic effect of the ether extract was compared with other oral hypoglycemic agents such as chlorpropamide and buformin. The ether extract of Polyonatum officinale showed a marked hypoglycemic effect by 1 hour after oral administration in hyperglycemic rats and rabbits but the ethanol extract did not exhibit the hypoglycemic effect. The hypoglycemic effect of the ether extract was potentiated by chlorpropamide while buformin was weak.

  • The Crustacean hyperglycemic hormone (CHH) has been shown to exist as multiple molecular forms in several crustacean species. In Penaeus monodon, a gene encoding CHH (so-called Pem-CHH1) was recently described. In this study, the molecular structures of two other CHH genes (Pem-CHH2 and Pem-CHH3) are reported. Both the Pem-CHH2 and Pem-CHH3 genes contain three exons that are separated by two introns that are similar to the structure of other genes in the same family. An analysis of the upstream nucleotide sequences of each Pem-CHH gene has identified the putative promoter element (TATA box) and putative binding sites for several transcription factors. The binding sites for CREB, Pit-1, and AP-1 were found upstream of all three Pem-CHH genes. A Southern blot analysis showed that at least one copy of each Pem-CHH gene was located within the same 10 kb genomic DNA fragment. These results suggest that the CHH genes are arranged in a cluster in the genome of P. monodon, and that their expression may be modulated by similar mechanisms.

  • A recent randomized and double-blind placebo-controlled clinical study bas indicated that Ganoderma lucidum polysaccharides (GLP) decrease blood glucose in patients with type II diabetes. The aim of this study was to investigate the effect of the GLP extract in alloxan-induced diabetic rats. Oral administration of GLP at 0.25, 0.5 and 1.0 g/kg for 4 weeks resulted in a reduction of blood glucose levels by 12.5, 18.7 and 33.7% respectively, while glibenclamide treatment brought the hyperglycemic value down to normal. The hyperglycemic effect was supported by a significant decrease in glycosylated haemoglobin and increased plasma insulin levels (p<0.01) in a dose- and time-dependent manner. This study showed that GLP has similar hypoglycemic effects as glibenclamide in alloxan-induced diabetic rats.

  • Purpose : Stress hyperglycemia is common in critically ill adult patients. It is known as a predictor of increased mortality, and intensive insulin therapy has been shown to improve the prognosis in such patients. We have investigated the relationship between early stress hyperglycemia and clinical outcomes in preterm infants. Methods : In this study, 141 preterm infants with a gestational age of less than 30 weeks were enrolled. The hyperglycemic group was defined as that having maximum glucose of more than 150 mg/dL (n=61) during the first 48 h of life, and the non-hyperglycemic group was defined as that having maximum glucose of less than 150 mg/dL (n=80). Perinatal history, severity of illness using the Clinical Risk Index for Babies (CRIB) score, clinical outcomes, and mortality of the two groups were compared. Results : There was no significant difference in the gestational age between the two groups, but the birth weight (P<0.001) was significantly lower, and the CRIB score (P<0.001) was significantly higher in the hyperglycemic group. Disseminated intravascular coagulation (P<0.001) and clinically suspected sepsis (P=0.046) were more common in the hyperglycemic group. Mortality was markedly higher in the hyperglycemic group (11.3% vs. 41.0%, P<0.001). On performing a stepwise multiple logistic regression analysis, hyperglycemia (OR 3.787; 95% CI 1.324 to 10.829), the CRIB score (OR 1.252; 95% CI 1.047 to 1.496) and birth weight (OR 0.997; 95% CI 0.994 to 1.000) was independently associated with higher mortality. Conclusion : Stress hyperglycemia within the first 48 h of life is independently related to increased morbidity and mortality in preterm infants.

  • The purpose of this study was to observe the effects of the feeding physiological activity substance in Saururus chinensis Baill extract on the improvement of the blood glucose, electrolyte (Na, K, CI) concentration and lipid metabolism in the serum of streptozotocin (STZ, 55 mg/kg B.W., I.P. injection)-induced hyperglycemic rats fed the experimental diets for 5 weeks. Concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglyceride (TG) and phospholipid (PL) in serum were significantly higher in the hyperglycemic group (group NSW), STZ (I.P.)+Saururus chinensis Baill leaf 3.5 g% extract group (group NSSL) and STZ (I.P.)+Saururus chinensis Baill root 3.5 g% extract group (group NSSR) than those in the control group (group Normal, basal diet+water). But the concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, TG and PL in serum were remarkably lower in the groups NSSL and NSSR than those in the NSW, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the groups NSSL and NSSR were significantly higher than in the group NSW. Electrolyte and creatinine concentrations in serum were significantly lower in the groups NSSL and NSSR than those in the group NSW. The activities of aminotransferase (AST, ALT), creatine phosphokinase (CPK), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) in serum were remarkably lower in the groups NSSL and NSSR than in the hyperglycemic group NSW. However, no significance was found in the comperative effect of the groups NSSL and NSSR. From the above results, it was suggested that Saururus chinensis Baill was effective in the improvement of the blood glucose, electrolyte, glucide and lipid metabolism in serum of STZ-induced hyperglycemic rats.

  • This study investigated the anti-diabetic effects of the mixed water extract (JDG 100) composed of Lycii Cortex, Acanthopanax senticosus and Cordyceps militaris on glucose-regulating key enzymes such as glucokinase (GK), acetyl-CoA carboxylase (ACC). In the current study, HepG2 cells were exposed to pathological condition such as hyperglycemic condition (4.5 g glucose/L) with JDG 100 and then experiments such as RT-PCR and Western blotting were carried out. JDG 100 treated cells increased to $168{\pm}0.04%$ and $182.4{\pm}0.03%$ in GK mRNA and protein expressions, respectively, compared to control. Treatment of the JDG 100 up-regulated ACC mRNA ($127.3{\pm}0.02%$) and protein ($126.7{\pm}0.24%$) of HepG2 cells in the high glucose media. These observations suggest that JDG 100 mixed water extract may have a potential as an anti-diabetic agent in type 2 diabetes mellitus.

  • 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.
