How does diabetes affect metabolism
Full size table Experimental design A To investigate the effect of DDW on metabolic changes occur in diabetes, diabetic and control rats were divided into two main groups: half of the animals were given DDW 25 ppm Dand the other half received normal tap water ppm Dboth provided ad how does diabetes affect metabolism.
Universitaet Innsbruck Rövid összefoglaló Concentric CE and eccentric EE exercises may differently affect glucose metabolism which may be additionally modified when exercises are performed in hypoxia, e. However, data on the effects of glucose metabolism due to CE and EE in hypoxia are scarce but would be of utmost importance considering the increasing number of persons suffering from impaired glucose tolerance or diabetes and the unique opportunities provided by the mountainous regions of the Alps to perform CE e. Metabolic responses to exercise may be largely mediated by interleukin 6 IL-6which is predominantly derived from the contracting limbs and may support the maintenance of metabolic homeostasis during exercise. In addition, IL-6 is elevated with acute and chronic altitude exposure at least partly mediated via adrenergic stimulation. Thus, the type of exercise as well as hypoxia may contribute to IL-6 elevations and differences in serum IL-6 concentrations might help to explain distinctions between responses of glucose metabolism to CE and EE at low and moderate to high altitude.
To determine whether DDW exerts its effects, at least partially, by modifying the action of insulin, diabetic rats were further divided into subgroups according to insulin treatment.
The control rats did not receive insulin treatment.

We did not want to achieve euglycaemia by insulin treatment, but to prevent severe acute complications only. Therefore, two different doses of insulin Huminsulin Lilly Normal I. The insulin was administered subcutaneously in equal portions twice daily 8.
Altitude, Exercise and Glucose Metabolism in Pre-diabetic Men
Treatments started at the 2nd week after STZ injection and lasted for an additional 8 weeks. Treatments started at the 2nd week after STZ injection and lasted for 4 weeks. Food intake, water consumption, and body weight were measured daily.
Blood samples from the tail vein and 24 h urine samples were collected once a week. The plasma samples were obtained by centrifugation at ×g for 15 min at 4 °C.
After measuring the volume, urine was centrifuged at × g for 10 min and the how does diabetes affect metabolism was used for analysis. Plasma glucose Plasma Glucose was determined spectrophotometrically using reagent kits from Reanal Finechemical Co. Budapest, Hungary. The plates were analyzed by a Biorad microplate reader. Plasma fructosamine concentration Plasma fructosamine concentration was determined spectrophotometrically using the micro method developed by Oppel et al.
In brief, fructosamine reagent was prepared by dissolving 50 mg nitroblue tetrazolium NBT, from Sigma, Budapest, Hungary in Standard was prepared from bovine serum albumin as described previously in detail [ 23 ]. Twenty µl of plasma or an adequate volume of standard solution was pipetted into the wells of a well plate in three parallels, respectively.

After the addition of µl reagent into each well, the plates were profoundly shaken and then incubated at 37 °C for 10 min. The initial absorbance was read at nm A1. Following a subsequent incubation for 10 min, the absorbance was read again at nm A2.
Fructosamine concentration Csample was calculated from Eq. In brief, 30 µl of blood samples collected without anticoagulants were hemolysated in µL deionised water. After further washing of the columns with washing buffer 10 mLµL of the hemolysate were transferred to the top of the columns and allowed to soak in.
Unbound hemoglobins were eluted by passing 8 mL of washing buffer through the column. The unbound fraction, containing most of the hemoglobin was diluted to cukor cukorbetegség kezelése 2 fok mL with washing buffer.
The absorbance of each fraction was measured at nm and the amount of hemoglobin bound glycosylated was calculated as a percentage of the total.
Isolation of the membrane fraction of soleus muscle Isolation of the membrane fraction of soleus muscle was performed according to Villanueva-Peñacarrillo ML et al. Briefly, soleus muscles from each rat hind limb were removed and trimmed of connective tissue, fat and nerves. The homogenate was centrifuged at ×g for 10 min at 4 °C, and the pellet was discarded. The supernatant was then centrifuged at ×g for 60 min in a Beckman SW55 rotor.
The pellet was resuspended in 0. The pellet was finally resuspended and homogenized in washing buffer, and the total membrane protein content was measured by the Bradford method. Western blot analyses The samples were prepared in 2 × Laemmli buffer containing mmol dithiothreitol and boiled in a water bath for 15 min.
The ODs of bands were determined by densitometry. All chemicals not mentioned otherwise were purchased from Sigma Budapest, Hungary.

Statistical analyses The results are presented as the mean ± SEM of n observations. Results DDW as drinking water reduced plasma glucose concentration and improved the metabolic parameters in diabetic rats To evaluate the effect of DDW on the glucose metabolism in streptozotocin STZ -induced diabetic rat model, first we aimed to test the 25 ppm D-concentration, which was the lowest D-concentration of DDW available.
In animals without any insulin treatment, DDW alone did not affect blood glucose concentration. These results indicate that deuterium depletion, in the presence of insulin, can affect blood glucose levels in diabetic animals.
