However, there was significant improvement in hepatic insulin resistance after only 2 wk of RIM treatment having a concomitant increase in plasma adiponectin levels; both were managed for the duration of the RIM treatment. CB1 receptor antagonism appears to have a direct effect on hepatic insulin level of sensitivity that may be mediated by adiponectin and self-employed of pronounced reductions in body fat. However, the relatively moderate effect on peripheral insulin level of sensitivity suggests that significant improvements may be secondary to reduced fat mass. = 20, 30.0 0.8 kg) used in a related publication (20) were housed in the Keck School of Medicine in the University of Southern California (USC) Vivarium less than controlled kennel conditions (12:12-h light-dark cycle). Animals were approved into this study following physical exam and a comprehensive blood panel. A chronic catheter attached to vascular access ports (Instech Solomon, Plymouth Achieving, PA) was surgically implanted 2 wk prior to the beginning of the study and secured subcutaneously to the underlying musculature at the back of the animal's neck. The catheter was put in the jugular vein and advanced to the right atrium for sampling of central venous blood. Access points for the ports were shaved and swabbed with providone-iodide before each sampling needle was put. Catheters were flushed with heparinized saline (10 U/ml) at least once/wk. Dogs were accustomed to laboratory methods and were utilized for experiments only if judged to be in good health, as determined by visual observation, body temperature, and hematocrit. Within the morning of each experiment, 19-gauge angiocatheters (Allegiance Healthcare, Ontario, CA) were inserted percutaneously into the saphenous vein for glucose infusion. The experimental protocol was authorized by the USC Institutional Animal Care and Use Committee. Diet. Dogs were fed a weight-maintaining standard diet of one can of Hill's Prescription Diet (10% carbohydrate, 9% protein, 8% excess fat, 0.3% dietary fiber, and 73% moisture; Hill's Pet Nourishment, Topeka, KS) and 825 g of dry chow (40% carbohydrate, 26.2% protein, 14% fat, and 2.9% fiber; LabDiet, Richmond, IN) for a period of 2C3 wk to ensure excess weight stabilization before any experiments were carried out. This standard diet consisted of 3,885 kcal/day time: 38.3% from carbohydrates, 26.1% from protein, and 34.5% from fat. Following excess weight stabilization (= 11) or placebo (PBO; = 9). Animals were matched for body weight (RIM = 31.7 1.3 kg, PBO = 31.8 1.5 kg). Rimonabant (Sanofi-Aventis, Paris, France) was encapsulated (AMC pharmacy, Burbank, CA) and given orally at 1.25 mgkg?1day?1, whereas the PBO group received gelatin pills. The dose of rimonabant was chosen on the basis of a study carried out in a small group of dogs (= 5) screening different doses ranging from 1.25 to 5 mgkg?1day?1. The dose of 1 1.25 mgkg?1day?1 was chosen because it did not produce any adverse clinical effects. Animals were managed within the HHFD throughout the 16 wk of treatment. Magnetic resonance imaging. During of the study, magnetic resonance imaging (MRI) scans were performed within the dogs, as explained previously (11). Thirty 1-cm axial abdominal images (T1 slices; TR 500 TE:14) were obtained using a General Electric 1.5 Tesla Horizon (software version 5.7) magnet. Of the 30 images obtained, 20 of these images were used for analysis of total trunk body fat, depending on the relative torso length of the animal. Images were analyzed using Scion Image (Alpha 4.0.3.2; Scion, Frederick, MD), which quantifies fat tissue (pixel value 121C254) and other tissue (20C120) in each slice. Fat volume was calculated by dividing the number of pixels counted as fat by the ratio of the total number of pixels (256 256) and known area (34.9 34.9 cm) for a 1-cm image. Total trunk fat and tissue were estimated as the integrated fat or tissue across all 20 slices. Percent fat was calculated as the total trunk fat.1. Changes in total body fat, omental fat, and subcutaneous fat depots in the placebo- (< 0.05 vs. + HFD. Magnetic resonance imaging was performed to determine adiposity- related changes in SI. Animals developed significant insulin resistance and increased visceral and subcutaneous adiposity after 6 wk of HFD. Treatment with RIM resulted in a modest decrease in total trunk fat with relatively little change in peripheral glucose uptake. However, there was significant improvement in hepatic insulin resistance after only 2 wk of RIM treatment with a concomitant increase in plasma adiponectin levels; both were maintained for the duration of the RIM treatment. CB1 receptor antagonism appears to have a direct effect on hepatic insulin sensitivity that may be mediated by adiponectin and impartial of pronounced reductions in body fat. However, the relatively modest effect on peripheral insulin sensitivity suggests that significant improvements may be secondary to reduced fat mass. = 20, 30.0 0.8 kg) used in a corresponding publication (20) were housed in the Keck School of Medicine at the University of Southern California (USC) Vivarium under controlled kennel conditions (12:12-h light-dark cycle).

Magnetic resonance imaging. During of the analysis, magnetic resonance imaging (MRI) scans had been performed for the canines, as referred to previously (11). Thirty 1-cm axial abdominal pictures (T1 pieces; TR 500 TE:14) had been obtained utilizing a General Electric powered 1.5 Tesla Horizon (software version 5.7) magnet. From the 30 pictures obtained, 20 of the pictures were useful for evaluation of total trunk surplus fat, with regards to the comparative torso amount of the animal. Pictures were examined using Scion Picture (Alpha 4.0.3.2; Scion, Frederick, MD), which quantifies extra fat tissue (pixel worth 121C254) and additional cells (20C120) in each cut. Fat quantity was determined by dividing the amount of pixels counted as extra fat by the proportion of the full total variety of pixels (256 256) and known region (34.9 34.9 cm) for the 1-cm image. Total trunk unwanted fat and tissue had been approximated as the integrated unwanted fat or tissues across all 20 pieces. Percent unwanted fat was computed as the full total trunk unwanted fat divided by the full total trunk tissues. Omental unwanted fat was thought as unwanted fat inside the peritoneal cavity within an 11-cm area from the thorax, using the cut on the known level where in fact the still left renal artery branches in the stomach aorta being a midpoint.In today’s research, although adiponectin amounts didn’t change using the onset of the high-fat diet, we discovered that adiponectin amounts were increased immediately with rimonabant treatment in a way that fasting adiponectin had increased by 50% after only 2 wk of rimonabant treatment. in peripheral blood sugar uptake.
