Male Wistar rats weighing 200–250 g were obtained from the Animal Center of National Cheng Kung University Medical College. STZ-induced diabetic rats, used as a type 1 diabetes model, were prepared by administering an intravenous injection of STZ (Sigma Chemical, St. Louis, MO) (60 mg/kg) to male Wistar rats aged 8–10 weeks after the animals were fasted for 3 days. Rats with plasma glucose concentrations ≥20 mmol/l in addition to polyuria and other diabetic features were considered to have type 1 diabetes. All studies were carried out 2 weeks after the injection of STZ. All animal procedures were performed according to the Guide for the Care and Use of Laboratory Animals of the National Institutes of Health as well as the guidelines of the Animal Welfare Act.

The rats were divided into two groups for the investigation. After fasting overnight, STZ-induced diabetic rats in group 1 received an intravenous injection of tramadol (Pairon Pharmaceuticals, Kaohsiung City, tramadol hcl use, Taiwan) at the desired doses, and blood samples (0.1 ml) were collected under sodium pentobarbital anesthesia (30 mg/kg i.p.) from the tail vein for measurement of plasma glucose, tramadol hcl use. In the preliminary experiments, tramadol treat migraine, tramadol was found to produce the maximal plasma glucose–lowering effect in STZ-induced diabetic rats 30 min after injection, tramadol hcl use. Thus, the effects of tramadol on plasma glucose, tramadol hcl use, insulin, and C-peptide were determined using blood samples collected at 30 min after the injection. STZ-induced diabetic rats receiving a similar injection of vehicle at the same volume were used as controls and defined as group 2, germany prescription tramadol. Further experiments were performed with pharmacological inhibitors, either naloxone or naloxonazine, tramadol lexapro addiction story, which were obtained from Research Biochemical (Natick, tramadol hcl use, MA), tramadol treat migraine. These inhibitors were intravenously injected into fasted rats 30 min before the injection of tramadol, tramadol hcl use.

STZ-induced diabetic rats received an intravenous injection of p-chlorophenylalanine (PCPA) at 300 mg/kg once daily for 3 successive days. The control group received the same volume of vehicle in the schedule, tramadol hcl use. Changes of 5-hydroxytrptamine (5-HT) were followed by the levels of 5-HT and 5-hydroxyindole acetic acid (5-HIAA) in plasma obtained from STZ-induced diabetic rats receiving PCPA or vehicle. Determination of 5-HT or 5-HIAA was performed by electrochemical detection as previously reported (14), tramadol hcl use. Then, plasma glucose–lowering activity of tramadol (50 μg/kg) in STZ-induced diabetic rats receiving PCPA was compared with that in vehicle-treated STZ-induced diabetic rats. Also, STZ-induced diabetic rats receiving oral administration of fluoxetine (Eli Lilly) at 20 mg/kg were used to estimate the alteration in plasma glucose (15).

The effects of tramadol on glucose uptake were studied using the uptake of radioactive glucose analog, 2-[1-14C]deoxy-d-glucose (2-DG), in isolated soleus muscle of STZ-induced diabetic rats. Hepatocytes isolated from another group of STZ-induced diabetic rats were also used to determine the effect of tramadol on [14C]glucose incorporation into glycogen, tramadol hcl use.

STZ-induced diabetic rats were given injections of vehicle, tramadol (50 μg/kg), tramadol hcl use, naloxone (10 μg/kg), or both naloxone and tramadol every 8 h, three times daily, into the tail vein. In the preliminary experiments, germany prescription tramadol, tramadol was found to significantly modify the mRNA and protein levels for GLUT4 and PEPCK in STZ-induced diabetic rats after 4 days of treatment. Thus, the effects of tramadol on gene expression of GLUT4 and PEPCK were determined using samples collected after 4 days of treatment. Normal rats received a similar treatment of vehicle and were used as controls. After the final treatment, animals were killed without fasting. Liver and soleus muscle were immediately removed, tramadol hcl use, frozen in liquid nitrogen, and stored at −70°C for Northern and Western blot analysis. Blood samples were also collected from the femoral vein of these rats before they were killed.

Blood samples (0.1 ml) were collected by a chilled syringe containing 10 IU heparin from the tail vein of the rats while they were under anesthesia with sodium pentobarbital (30 mg/kg i.p.). Concentration of plasma glucose was measured by the glucose oxidase method via an analyzer (Quik-Lab; Ames/Miles, Elkhart, tramadol hcl use, IN) (16). Radioimmunoassay (RIA) was performed to measure plasma insulin or C-peptide using a commercial kit from Linco (St. Charles, MO). A plasma sample from an STZ-induced diabetic rat was added with standard insulin or C-peptide to raise the level into the detectable range of RIA. The given value was obtained by subtracting the added standard from the measured value, tramadol hcl use.

Soleus muscle was isolated from STZ-induced diabetic rats and divided into long longitudinal strips (35–25 mg per strip) as previously described (17). After a 30-min preincubation period, the muscle tissue was transferred to fresh incubation flasks with or without the presence of antagonist (either naloxone or naloxonazine) at appropriate concentrations for 30 min at 37°C and then incubated with tramadol at the desired concentrations at 37°C for another 30 min under continuous shaking at 40 cycles/min. The muscle tissue was subsequently incubated with 50 μl Krebs-Ringer bicarbonate buffer (KRBB) containing 2-DG (1 μCi/ml) (NEN Research, Boston, MA) for 5 min at 37°C. Reactions were terminated by quickly blotting the muscles and dissolving them in 0.5 ml of 0.5 N NaOH for 45 min before neutralization with 0.5 ml of 0.5 N HCl. After centrifugation, 800 μl of each supernatant was mixed with 1 ml aqueous counting scintillant (ASC; Amersham, tramadol lexapro addiction story, Arlington Heights, IL) and the radioactivity was determined using a β-counter (Beckman LS6000, tramadol treat migraine, Beckman, Fullerton, CA) (17). Uptake of 2-DG, assessed after preincubation of the muscle with 20 μmol/l cytochalasin B (Sigma Chemical), was subtracted from the total muscle–associated radioactivity (18). Specific 2-DG uptake was expressed as the percentage of basal uptake that was obtained from soleus muscle incubated with KRBB only.

Hepatocytes were prepared as previously described (19). After the 30-min preincubation period in KRBB at 37°C, 2 × 106 hepatocytes were transferred to fresh incubation flasks containing [U-14C]glucose (0.25 μCi/ml) (NEN Research), with or without the presence of antagonist, at appropriate concentrations for 30 min at 37°C and then incubated with tramadol at the desired concentrations at 37°C for 1 h, tramadol hcl use, which was the optimal time obtained from preliminary experiments under continuous shaking. The incorporation of [U-14C]glucose into glycogen was determined by ethanol precipitation (20). Label incorporation into glycogen was expressed as the percentage of basal level that was obtained from hepatocytes incubated with KRBB only.

Total RNA was extracted from liver or soleus muscle of experimental animals using the Ultraspec-II RNA extraction system (Bioteck, Houston, TX), tramadol treat migraine. For Northern blotting analysis, RNA (20 μg) was denatured by heating at 55°C for 15 min in a solution containing 2.2 mmol/l formaldehyde and 50% formamide (vol/vol). Aliquots of total RNA were then size-fractionated in a 1.2% agarose/formaldehyde gel, tramadol hcl use. Ethidium bromide staining was used to identify the position of the 18S and 28S rRNA subunits and to confirm that equivalent amounts of undegraded RNA had been loaded. The RNA was transferred to a Hybond-N membrane (Amersham, tramadol hcl use, Bucks, U.K.). GLUT4 and PEPCK mRNA levels were detected using random prime-labeled full-length cDNA under stringent hybridization conditions. Intensity of the mRNA bands on the blot was quantified by scanning densitometry (Hoefer, San Francisco, tramadol treat migraine, CA). The response of β-actin was used as an internal standard.

After homogenization of liver and skeletal muscle using a glass/Teflon homogenizer, the homogenates (50 μg) were separated by SDS-PAGE, tramadol hcl use, and Western blot analysis was performed as previously described (17) using either anti-rat antibody to bind GLUT4 (1:1,000) (Genzyme Diagnostics, Cambridge, MA) in skeletal muscle or another anti-rat antibody (1:1,000) to bind PEPCK in liver, tramadol lexapro addiction story. Blots were incubated with the appropriate peroxidase-conjugated secondary antibodies, tramadol hcl use. After removal of the secondary antibody, blots were washed as described above and developed by autoradiography using the ELC-Western blotting system (Amersham, Braunschweig, Germany). Densities of the obtained immunoblots were quantified using a laser densitometer, with GLUT4 at 45 KDa and PEPCK at 69.5 KDa.

The plasma glucose–lowering activity was determined in rats that received tramadol injection under anesthesia. Data are expressed as the means ± SE for the number (n) of animals in each group, tramadol lexapro addiction story, as indicated in the tables and figures. Repeated measures of analysis of variance were used to analyze the changes in plasma glucose and other parameters. Where appropriate, tramadol hcl use, the Dunnett range post hoc comparisons were used to determine the source of significant differences. The concentration for 50% effect (ED50) was obtained from nonlinear regression analysis, tramadol hcl use. P < was considered statistically significant.
