Objective: The purpose of this study is to investigate the elevated blood glucose levels in the postoperative period are associated with an increased risk of deep wound infection in diabetic individuals undergoing lumbar spine surgery. Methods: Of 2896 patients who underwent lumbar spine operations by one surgeon between 1993 and 2002, 329(11.4%) were diabetics. The rate of deep wound infections in diabetic patients was 6.4%, versus 3.2% for nondiabetics. 152 patients had their operation before implementation of the protocol and 177 after implementation. Charts of the diabetic patients were reviewed. Mean blood glucose levels were calculated from documented results of finger-stick glucometer testing. Results: Twenty-one diabetic patients suffered deep wound infection. Infected diabetic patients had a higher mean blood glucose level through the first 2 postoperative days than noninfected patients($230{\pm}6.9$ versus $175{\pm}3.8mg/dL$; p<0.003) and had a long operation time($216{\pm}57.9$ versus $167.5{\pm}42.2$ minute; p<0.05). Multivariable logistic regression showed that mean blood glucose level for the first 2 postoperative days, long operation time, and use of the instrumentation(p<0.02) were all related predictiors of deep wound infection. Institution of a protocol of postoperative continuous intravenous insulin to maintain blood glucose level less than 200mg/dL was began in september 1997. This protocol resulted in a decrease in blood glucose levels for the first 2 postoperative days and a concomitant decrease in the proportion of patients with deep wound infection, from 8.3%(11/132) to 5.1%(10/195) (p<0.02). Conclusion: The incidence of deep wound infection in diabetic patients is reduced after implementation of a protocol to maintain mean blood glucose level less than 200mg/dL in the immediate postoperative period.

Chrysanthemum zawadskii (CZ) is a perennial herb belonging to the Asteraceae family. CZ is used medicinally to treat inflammatory and uterine diseases in Asia. CZ was extracted with 50% ethanol and CZ extract (CZE; at 125, 250, and 500 mg/kg body weight) was administered orally every day for 5 or 6 weeks to investigate the anti-diabetic effects in streptozotocin (STZ)-induced rats and STZ + high-fat diet (HFD)-fed mice. CZE significantly decreased fasting blood glucose levels in STZ- and STZ + HFD-induced diabetic models. In addition, glucose tolerance and insulin tolerance were improved in the STZ + HFD + CZE group by increasing insulin levels and decreasing hemoglobin A1c (HbA1c) levels in serum. Furthermore, CZE supplements decreased components of the serum lipid profile such as triglyceride, total cholesterol, and low-density lipoprotein cholesterol levels. These results suggest that CZE may be a potential candidate for controlling hyperglycemia.

Secondary metabolites enable plants to protect themselves from herbivorous insects. Among these, cucurbitacin B (cuc-B) is a bitter-tasting compound with promising pharmacological potential. Dietary exposure to cuc-B lowered the hemolymph glucose levels of Drosophila melanogaster fed with a high carbohydrate diet, which is homologous to high blood glucose in humans, and its effect was comparable to that of metformin, a well-known glucose-lowering drug. Furthermore, cuc-B reduced tissue sugar levels and glycogen levels, as well as triacylglycerol levels. Our results thus highlight the potential applicability of this compound to treat chronic metabolic diseases such as diabetes and obesity. Additionally, we analyzed sleep quality and taste-associative memory enhancement after cuc-B and metformin treatment. Both supplements increased nighttime bout length and metformin increased memory consolidation. Therefore, discarded shell of Cucurbitaceae could be processed into health supplements.

Object:The goal of this study was to examine the changes in body weight and glucose levels of the patients treated with risperidone, clozapine or haloperidol in order to compare the effect of risperidone or clozapine with that of haloperidol. Methods:For nine months(January to September, 2003), a prospective study was performed in 60 patients with chronic schizophrenia who were in Seoul National Hospital. Two-week period was required for a drug wash-out. The patients were randomly assigned to risperidone, clozapine and haloperidol groups. They were given risperidone(n=20), clozapine(n=20) and haloperidol(n=20), respectively, everyday for 12 weeks. To examine the effects of these drugs on body weight and fasting glucose levels, we measured body weight and glucose levels of all the patients first without the drug treatment and at each end of 4, 8, and 12-week periods with the treatment. And we examined the differences among three groups in the changes of body weight and fasting glucose levels. Results:There were no significant differences in the changes of the body weight and fasting glucose levels between the atypical antipsychotics(risperidone or clozapine) and the typical antipsychotics(haloperidol). Conclusion:The study in the patients with chronic schizophrenia suggests that risperidone or clozapine do not cause any additional effects on body weight or glucose levels compared to haloperidol.

Objective : This study was designed to investigate anti-diabetic effects of fermented soy bean extract with herbal medicines (Godjang) in diabetic rat models induced by streptozotocin (STZ) injection. Method : Changes in body weight, drinking water, and food intake were observed for 4 weeks before and after induction of diabetes mellitus in rats. The anti-diabetic capacity of Godjang was analyzed by fasting blood glucose (FBG) every week. Also, after 4 weeks of administration, the oral glucose tolerance test (OGTT) was performed, and then blood levels of insulin were checked. And serum levels of total cholesterol and triglycerides were determined. Histomorphological changes of liver, kidney and pancreatic tissues were also observed in STZ-induced diabetic rats and Godjang administered rats. Result : In Godjang administered group, body weight and water intake were more lower than that of STZ-induced diabetic rats. FBG was decreased in the Godjang administered group than STZ-induced diabetic group. According to OGTT, blood glucose levels at 30 minutes and 60 minutes significantly decreased in Godjang administered group than in STZ-induced diabetic control group. Administration of Godjang extract for 4W significantly decreased levels of serum glucose, total cholesterol (TC), triglycerides (TG) in diabetic rats. In histomorphological analysis of kidney, liver, Godjang administrated groups showed the inhibition of pathological damage. Conclusion : These results suggest that Godjang extract has an anti-diabetic action through decrease in serum glucose, TC, TG levels and recovery of the morphological changes in kidney and liver in STZ-induced diabetic rats.

This study investigates the effects of a raw diet (RD) on blood glucose and lipid metabolism in non-diabetic (normal) and streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley vats were assigned to four groups (normal control, normal RD, diabetic control, and diabetic RD), for the four-week experimental period. The control groups were fed the AIN diet and the RD groups were fed a diet consisting only of raw materials. Weight gain was statistically lower in the RD group than the control. fasting plasma glucose was significantly lower in the diabetic RD group compared to the diabetic control group. The levels of triglycerides (TG), and of total cholesterol (TC) and LDL-cholesterol in the plasma, were lower in the RD groups than the control groups, but not significantly. There was a statistically significant decrease in the levels of TG and TC in the livers of the diabetic RD group, compared to the diabetic control group. The fecal levels of total lipids, TG, and TC were significantly higher in the RD groups, compared to the non-RD groups. It can be postulated that this raw diet may possess substantial hypoglycemic/hypolipidemic properties in diabetic rats.

Body weights and blood biochemical values in chickens infected with reticuloendotheliosis virus (REV)-HI, a Korean isolate, were studied. REV-HI causes severe body weight depression in chickens inoculated but not in chicken contact-infected. Body weights of infected chickens in 3, 4, and 5 weeks after infection were 78%, 76% and 65% of those of control respectively. Blood glucose levels in REVinfected chickens were extremely high compared with those in control (226 $\geq$ 21 vs. 814 $\geq$91.3 mg/dl in week 2) during the experiment period. Triglyceride levels in REV-infected chickens were significantly higher in week 2 and 3, whereas in week 4, REV-infected chickens showed significantly lower levels than the control. Blood lipase, amylase and alkaline phosphatase levels of REV-infected chickens in week 2 were significantly higher, whereas cholesterol, magnesium and calcium values in week 4 were significantly lower than the control. Other blood biochemical values such as alkaline aminotransferase, aspartate aminotransferase, and $\gamma$-glutamyltransferase were nonsignificantly different from the control. These above results suggest that weight depression by REV may be related with increase of blood glucose, which indicated that REV-infected chickens could not use blood glucose as energy source.

During the past decade, many salivary parameters have been used to characterize disease states. Ghrelin (GAH) is recently-discovered peptide hormone secreted mainly from the stomach but also produced in a number of other tissues including salivary glands. The aim of this work was to examine the relationship between active (aGAH) and inactive (dGAH) ghrelin in the saliva and other salivary parameters in type II diabetic patients and healthy controls. Salivary parameters were assessed in a single measurement of unstimulated whole saliva from 20 obese and 20 non-obese type II diabetes patients, and in 22 healthy controls. Total protein and alpha-amylase were determined by colorimetric methods, and glucose by the glucose-oxidase method. Saliva aGAH and dGAH levels were measured using a commercial radioimmunoassay (RIA) kit. Salivary concentrations of aGAH and dGAH ghrelin were more markedly decreased in obese diabetic subjects than in the two other groups. Glucose and alpha-amylase levels were higher in diabetic subjects than in controls. Furthermore, there were correlations between GAH levels and BMI, and between GAH and blood pressure. However, there was no marked variability in saliva flow rates among the groups. These results indicate that measurement of salivary GAH and its relationship to other salivary parameters might help to provide insight into the role of ghrelin in diabetes.

This study was performed to explore the effects of the fermented functional extracts (FE) on blood glucose and lipid levels in diabetes. FE were created by mixing 9 kinds of plants with sea water and then allowing the mixture to ferment for 1 year. FE were supplemented in the feed of streptozotocin (STZ)-induced diabetic rats at 1%, 3% and 5%. The 1% feeding group showed the lowest weight loss of the three experimental groups. The blood glucose and glycosylated hemoglobin level were significantly decreased in the FE fed rats compared to the diabetic control (DMC) group. The lipid levels in serum were decreased in 1% and 3% FE fed rats in comparison to the DMC group, and there was no significant difference in triglyceride levels due to the FE concentration. The HDL-C level was significantly increased in rats with FE supplemented diets, compared to the DMC group. The levels of lipid peroxides in liver tissue were significantly decreased in FE fed diabetic rats, and the hepatic glycogen content was increased in rats receiving supplements. As a result of these studies, we believe 1% FE may be the optimum level for controlling blood glucose and alleviating hyperlipidemia in STZ-induced diabetic rats.

This study evaluated the effects of milk fermented with Pediococcus acidilactici strain BE and Pediococcus pentosaceus strain M103 on diabetes in rats (Rattus norvegicus). The bacteria were separately used as starter cultures for milk fermentation, and the products were then fed to diabetic rats for 15 days. Blood glucose levels, immunohistochemical and histological indicators, lipid profiles, and total lactic acid bacterium counts were evaluated before and after treatment. The administration of milk fermented with P. acidilactici strain BE reduced blood glucose levels from 410.27±51.60 to 304.07±9.88 mg/dL (p<0.05), similar to the effects of metformin (from 382.30±13.39 mg/dL to 253.33±40.66 mg/dL, p<0.05). Increased insulin production was observed in diabetic rats fed milk fermented with P. acidilactici strain BE concomitant with an increased number and percentage area of immunoreactive beta-cells. The structure of insulin-producing beta-cells was improved in diabetic rats fed milk fermented with P. acidilactici strain BE or metformin (insulin receptor substrate scores of 5.33±0.94 and 3.5±0.5, respectively). This suggests that the administration of milk fermented with P. acidilactici BE potentially reduces blood glucose levels and improves pancreatic beta-cell function in diabetic rats.
