Minerals are individual of the components of foods and are not produced in the body but essential for best possible health. Several essential metals are vital for the appropriate performance of various enzymes, transcriptional factors and proteins that are essential in various biochemical paths. Metals like zinc (Zn), magnesium (Mg), and manganese (Mn) are cofactors of hundreds of enzymes. Zn is involved in the synthesis and secretion of insulin from the pancreatic ${\beta}-cells$. Chromium (Cr) increases the insulin receptors activity on target tissues, mainly in muscle cells. Insulin hormone is required to maintain the blood glucose amount in normal range. Continual increase of blood serum glucose level leads to marked chronic hyperglycemia or diabetes mellitus. Deficiency of insulin or its resistance, blood glucose level exceeds the upper limit of the common range of 126 mg/dl. Poor glucose control and diabetes changes the levels of essential trace elements such as Zn, Mg, Mn, Cr, iron etc. by rising urinary excretion and their related decrease in the blood. The aim of this article to discusses the important roles of essential trace elements in particular perspective of type 2 diabetes.

In this study, rice candy was produced with mulberry leaf and its effect on the lowering blood glucose level was assessed. The results were as follows: The recovery rate of mulberry leaf powder was 32.7%. The contents of crude protein, lipid, ash and crude fiber of mulberry leaf were 19.54%, 4.82%, 12.80%, and 11.27%, respectively. The sensory evaluation revealed that the rice candy added with 1% mulberry leaf powder showed slightly hi인or palatability score than that of 2%, but we decided that 2% addition of mulberry leaf powder would be preferred over 1% if considering both the physiological function and the sensory acceptability. The blood glucose level after ingesting the rice candy with mulberry leaf lowered by 31%, more than that of control.

Dose-dependent increasesin blood glucose were produced by epinephrine and clonidine in fasted male mice. Isoproterenol was ineffective in increasing blood glucose at lower doses ($10^{-8}M$/kg-$10^{-7}M$/kg); with higher dose ($10^{-6}M$/kg) the glucose level was increased. The hyperglycemia induced by epinephrine was inhibited by yobimbine, prazosin and propranolol, indicating that the hyperglycemic effect of epinephrine is mediated by alpha-1, alpha-2 and beta adrenoceptor. When clonidine (10$^{-6}$ M/kg) was administered simultaneously with sioproterenol ($10^{-6}M$/kg), an enhenced hyperglycemic effect was observed. The increment produced by clonidine plus isoproterenol was higher than that by clonidine alone. These increment produced by clonidine plus isoproterenol was higher than that by clonidine alone. These results suggest that stimulation of alpha-2 adrenoceptor may be reponsible for the exertion of the hyperglycemic effect by beta agonists in fasted mice.

Purpose: The purpose of this study was to examine the effect of a walking program on body mass index (BMI), blood pressure, cholesterol, and blood glucose in community-dwelling older adults. Method: A quasi-experimental research design (one group pretest-posttest) was employed. Participants were recruited in Seoul and a total of 57 community-dwelling older adults completed the 10-week walking program. Descriptive statistics and paired t-tests were used in the data analysis by SPSS WIN 14.0. Result: The participants showed lower BMI, systolic blood pressure, diastolic blood pressure, cholesterol level, and blood glucose level after than before participation in the walking program. Body mass index significantly decreased (t= 2.911, p= .005) after completing the walking program. There were, however, no significant changes in blood pressure, cholesterol, and blood glucose after completing the walking program. Conclusion: Findings of this study indicated that the 10-week walking program had favorable effect on BMI. Future research needs to target various older adult groups during a long-term period.

Background: Pembrolizumab, an anti-cancer drug, is known to increase the activity of the immune system, leading to side effects called immune-related adverse events (irAE), including type 1 diabetes. This study analyzed the correlation between blood glucose level and pembrolizumab administration and investigated the covariates that affect those changes in cancer treatment. Methods: The information of 133 adult cancer patients was obtained from the electronic medical record (EMR) to identify the changes in random blood glucose (RBG) levels during the pembrolizumab treatment. Subjects were classified into subgroups according to their baseline RBG level, history of diabetes, and the use of steroids, and linear regression analysis was conducted. In addition, a secondary analysis was performed within the group of subjects having a strong correlation to glycemic change, which was based on the Pearson correlation coefficient being less than -0.7 or greater than +0.7. Univariate and multivariate logistic regressions were conducted to identify the risk factors to glycemic increase. Results: The RBG level tended to descend without significant differences in total patients during the administration period of pembrolizumab. Despite the insignificance, the logistic regression analysis presents that the odds ratios of baseline RBG less than 130 mg/dL, prophylactic steroid use, and higher dose of pembrolizumab per cycle (mg/kg/cycle) were greater than 1. Conclusions: Prophylactic administration of steroids and a higher dose of pembrolizumab per cycle may increase the blood glucose level as irAE in cancer patients with a strong tendency to glycemic change.

This study was conducted to figure out the differences of the BMI, blood lipids, blood pressure and nutrient intakes by serum insulin concentration among adults in Korea. Ninety-three subjects(male : n=37, female : n=56) participated in this study. The subjects were grouped by serum insulin concentrations into two groups-hyperinsulinemia group(n=17) and normoinsulinemia group(n=76). Anthropometric measurements, blood lipid profiles, blood pressure, oral glucose tolerance test, and daily nutrient intakes were analyzed. And serum glucose and insulin secretion pattern as shown through and oral glucose tolerance test were performed. BMI (p<0.05) and WHR(p<0.01) were significantly higher in hyperinsulinemic group than in normoinsulinemia group. There was no differences in fasting blood glucose level between groups, but total glucose area (p<0.001) and insulin glucose resistance(p<0.001) were significantly higher in hyperinsulinemia group than in normoinsulinemia higher in hyperinsulinemia group, but HDL-cholesterol(p<0.05), and systolic blood pressure(p<0.05) were significantly higher in hyperinsulinemia group, but HDL-cholesterol(p<0.001) was significantly lower in hyperinsulinemia group. They showed significant differences in energy, carbohydrate, potassium, riboflavin, niacin and dietary fiber intakes(p<0.05), the intake of those nutrients were low in normoinsulinemia group. Further investigation is necessary to determine the effects of amounts and types of carbohydrate and dietary fiber on serum insulin concentrations.

This study was conducted to examine the hypoglycemic effects of complexcity extract(DB 55) from five oriental medicinal plants on the intake of food, body weight, blood glucose level, insulin content, serum GOP, GPT, BUN and hematocrit value in streptozotocin(STZ)-induced diabetic rats. General nutritional composition was also assessed. Thirty- five male Sprague-Dawley rats were assigned to five groups : normal control group(NC), STZ-diabetic control group (STZ-control), STZ-diabetic DB-1 group(DB 55-1), STZ-diabetic DB-2 group(DB 55-2) and STZ-diabetic DB-3 group(DB 55-3). The animals were fed an experimental diet for 12 weeks. Body weight gain of the STZ-diabetic group was significantly lower but diet intake was significantly higher than the NC group. Blood glucose levels of the DB-1, DB-2 and DB-3 rats were significantly lower than the STZ-control animals. Insulin level of STZ-control rats was lower than the NC serum GOT, GPT and BUN levels were significantly higher in the NC group, but hematocrit value was not significant as compare to the STZ-diabetic group. Blood glucose level was lower observed for the DB 55-1, DB 55-2 and DB 55-3 group. The results will be useful in oriental diet therapy and in the developing functional food resources.

To evaluate the adrenergic receptors for glycogenolytic responses to catecholamine, the blood glucose level, liver glycogen content and muscle glycogen level in rats were studied with treatment of epinephrine, norepinephrine and isoproterenol. In addition, to study the possibility of interconversion of adrenergic receptors, the effects of catecholamines in feeding animal were compared with those in fasting animal. The results are summarized as follow; 1) Epinephrine and norepinephine showed dose dependent increase of blood glucose level but the effect of isproterenol was not significant. 2) The prandial states of animal did not influence on effects of catecholamines on blood glucose level. 3) Liver glycogen contents were lowered by epinephrine or by norepinephrins but effect of isoproterenol was not significant. 4) Glycogen content of skeletal muscle was significantly lowered by isoproterenol and. epinephrine shifted the dose-response curve to right, but the effect of norepinephrine was not significant. 5) The effects of epinephrine and norepinephrine on blood glucose were significantly blocked by ergotamine but not by propranolol. These results indicate that the glycogenolytic response to adrenergic agents in rat is mediated by an alpha-receptor in liver and by a beta-receptor in skeletal muscle.
