A single dose of reserpine (1 mg/kg body weight, injected subcutaneously) induced hyperglycaemia which persisted for at least 6 hours in rats kept in slings, but no significant alteration in the level of blood sugar was observed in free-running rats. The administration of a single dose of reserpine to unrestrained rats 3 hours prior to a test dose of insulin (0.5 units/kg body weight intramuscularly) or of tolbutamide (125 mg/kg per os) resulted in a decrease in the sensitivity of the animals to the hypoglycaemic action of these two compounds. Pretreatment with reserpine (1 mg/kg for 2 days) resulted in a failure of a single dose (0.5 mg/kg) of this compound to elevate blood glucose levels, in restrained rats, but such reserpine pretreated animals displayed a decreased hypoglycaemic response to a test dose of insulin.The hyperglycaemia observed in restrained rats following the injection of a single dose of reserpine was still observed in animals from which the pancreas had been completely removed, indicating that the change in blood glucose level in response to reserpine in these animals was not dependent on the presence of a pancreatic factor.

ABSTRACT Multiple serial blood glucose level determinations in individual mice were performed on small blood samples (10–25 μl) using the orbital bleeding technique. Glucose was determined specifically by a known enzymatic reaction. Blood glucose determined in this way was found a parameter of high reproducibility and precision, the latter being shown by the finding that differences between individual animals were highly significant in practically all the experiments. The standard deviation of the single measurement in normal mice was ± 8.2 mg/100 ml as determined from 600 samples, which indicated that the technique allows of the detection of blood sugar level changes of about 15 mg/100 ml or more with very high significance, in a group of 5 mice. In the sampling procedure as such, intravenous or subcutaneous saline injections did not necessarily have any effect on the blood glucose level, but interpretation of slight blood sugar changes under experimental conditions should always be based on a comparison with control groups, since the latter may sometimes show a slight but significant change. In normal non-fasting mice (NMRI strain) significant differences in homoeostatic blood glucose level adjustments were demonstrated. In acutely adrenalectomized mice blood glucose levels were lower and more variable than in normals. Alloxan injection (70 mg/kg) was followed in individual mice by a triphasic blood sugar response, as is known from other species.

This research aimed to determine the effect of daun sendok (Plantago major L.) extract on the blood glucose level of Balb/C mice induced by streptozotocin. This study was a laboratory experimental pre and post-test control group design. The subjects used were 16 male mice. Then, mice were induced with streptozotocin by a dose of 65 mg/kg body weight intraperitoneally freshly dissolved in 0.02 M citrate saline buffer. Mice used were mice with blood glucose levels â‰¥200 mg/dL. Furthermore, mice were divided into 2 groups by a simple random sampling. Group 1 was given metformin in a dose of 1.3 mg/mice/day and group 2 was given daun sendok extract in a dose of 1000 mg/kg body weight/day. At the 2nd week, it was measured for the glucose levels from the blood of mice tail by a Blood Glucose Stick Meter (Gluco DrTM). The data obtained were statistically analyzed by independent samples t-test by using SPSS Programme for Microsoft Windows release 17.0. The significance was set at p<0.05. The difference of average blood glucose levels pre vs post experiment, metformin group was -145.87 mg/dL and daun sendok group was -85.00 mg/dL (p=0.024). The experiment results showed that daun sendok extract in a dose of 1000 mg/kg body weight/day could reduce the blood glucose levels in Balb/C mice induced by streptozotocin.

Abstract Background Blood glucose levels that are too high or too low after traumatic brain injury (TBI) negatively affect patient prognosis. This study aimed to demonstrate the relationship between blood glucose levels and the Glasgow Outcome Score (GOS) in TBI patients. Methods This study was based on a randomized, dual-center, open-label clinical trial. A total of 208 patients who participated in the randomized controlled trial were followed up for 5 years. Information on the disease, laboratory examination, insulin therapy, and surgery for patients with TBI was collected as candidate variables according to clinical importance. Additionally, data on 5-year and 6-month GOS were collected as primary and secondary outcomes, respectively. For multivariate analysis, a generalized additive model (GAM) was used to investigate relationships between blood glucose levels and GOS. The results are presented as odds ratios (ORs) with 95% confidence intervals (95% CIs). We further applied a two- piecewise linear regression model to examine the threshold effect of blood glucose level and GOS. Results A total of 182 patients were included in the final analysis. Multivariate GAM analysis revealed that a bell-shaped relationship existed between average blood glucose level and 5-year GOS score or 6-month GOS score. The inflection points of the average blood glucose level were 8.81 (95% CI: 7.43–9.48) mmol/L considering 5-year GOS as the outcome and were 8.88 (95% CI 7.43−9.74) mmol/L considering 6-month GOS score as the outcome. The same analysis revealed that there was also a bell relationship between average blood glucose levels and the favorable outcome group (GOS score ≥ 4) at 5 years or 6 months. Conclusion In a population of patients with traumatic brain injury, blood glucose levels were associated with the GOS. There was also a threshold effect between blood glucose levels and the GOS. A blood glucose level that is either too high or too low conveys a poor prognosis. Trial registration ClinicalTrials.gov NCT02161055. Registered on 11 June 2014.

Challenges in lifestyle, such as increasesin energy intake and decreasesin physical activity are causing overweight and obesity leading to epidemic increases in type II Diabetes Mellitus. The research approach used for this study was evaluative approach and the research design was true experimental design. 60 patients with type II diabetes, 30 in experimental group and 30 in control group were selected for this study by using purposive sampling technique. Data was collected with the help of self-structured interview schedule. Descriptive statistics (frequency, percentage, mean and standard deviation) and inferential statistics (chi-square, paired ‘t’ test) were used to analyse the data and to test the hypotheses. In the experimental group,the pre-test mean score was 2.966, mean percentage was 59% and standard deviation was 1.129 and in post-testmean score was 2.533, mean percentage was 50.66% and standard deviation was 1.074 with effectiveness of 8.34% and paired‘t’ test value of t=3.971,which was statistically significant (p<0.05) which is an evidence ofthe effectiveness of Amla juice in reducing blood glucose level. Comparison of blood glucose levels in experimental and control groups, shows that the value is statistically highly significant, as was observed from the unpaired ‘t’ test value of 13.39 with P value of <0.05, which is an evidence indicatingthe effect of Amla juice in reducing postprandial blood glucose levels. The resultsfound that the administration of Amla juice did have aneffect in reducing blood glucose level in the experimental group. By comparing the findings of pre-test and post test between the experimental group and the control group,the effect was identified (assessed). The study concluded that the Amlajuice is effective in reducing blood glucose level.

The calibration method is an alternative method that can be used to analyze the relationship between invasive and non-invasive blood glucose levels. Calibration modeling generally has a large dimension and contains multicolinearities because usually in functional data the number of independent variables (p) is greater than the number of observations (p>n). Both problems can be overcome using Functional Regression (FR) and Functional Principal Component Regression (FPCR). FPCR is based on Principal Component Analysis (PCA). In FPCR, the data is transformed using a polynomial basis before data reduction. This research tried to model the equations of spectral calibration of voltage value excreted by non-invasive blood glucose level monitoring devices to predict blood glucose using FR and FPCR. This study aimed to determine the best calibration model for measuring non-invasive blood glucose levels with the FR and FPCR. The results of this research showed that the FR model had a bigger coefficient determination (R2) value and lower Root Mean Square Error (RMSE) and Root Mean Square Error Prediction (RMSEP) value than the FPCR model, which was 12.9%, 5.417, and 5.727 respectively. Overall, the calibration modeling with the FR model is the best model for estimate blood glucose level compared to the FPCR model.
