Chronic diabetic rat, induced by streptozotocin, showed high blood glucose but low liver glycogen levels. The diabetic liver had subnormal amounts of glycogen synthetase and its I form when assayed in both 8000 × g supernatant and glycogen pellet suspensions. The pellet suspension of the control liver retained 68% synthetase I activity; the diabetic liver retained only 19.5%. The addition of deproteinized liver extract to the pellet suspension increased the activity of synthetase either in the presence or absence of glucose-6-PO4 for both groups of animals to different degrees. The deproteinized liver extract of the diabetic rat contained little ATP, less glucose-6-PO4, and slightly more inorganic phosphate than that of the control rat. The significance of these observations is discussed.

Diabetic Rat Model

Background: Type 2 Diabetes Mellitus (T2DM) is a world-wide metabolic disease with no cure from drugs and treatment. In China, The Traditional Chinese Medicine (TCM) herbal formulations have been used to treat T2DM for centuries. Methods: In this study, we proposed a formula called ShenQi Compound (SQC), which has been used in clinical therapeutics in China for several years. We evaluated the effect of SQC in a spontaneous diabetic rat model (GK rats) by detecting a series of blood indicators and performing histological observations. Meanwhile, the gene microarray and RT-qPCR experiments were used to explore the molecular mechanism of SQC treatment. In addition, western medicine, sitagliptin was employed as a comparison. Results: The results indicated that SQC and sitagliptin could effectively improve the serum lipid (blood Total Cholesterol (TC) and blood Triglycerides (TG)), hormone levels (serum insulin (INS), Glucagon (GC) and Glucagon-Like Peptide-1 (GLP-1)), alleviated the inflammatory response (hypersensitive C-Reactive Protein (hsCRP)), blood glucose fluctuation (Mean Blood Glucose (MBG), standard deviation of blood glucose (SDBG) and Largest Amplitude of plasma Glucose Excursions (LAGE)), pancreatic tissue damage and vascular injury for T2DM. Compared with sitagliptin, SQC achieved a better effect on blood glucose fluctuation (p<0.01). Meanwhile, the gene microarray and RT-qPCR experiments indicated that SQC and sitagliptin may improve the T2DM through affecting the biological functions related to apoptosis and circadian rhythm. Moreover, SQC might be able to influence the mTOR signaling pathway by regulating Pik3r1, Ddit4 expression. Conclusion: All these results indicate that SQC is an effective therapeutic drug on T2DM. Notably, SQC presents an obvious blood glucose fluctuation-preventing ability, which might be derived from the regulation of the mTOR signaling pathway.

Unrestrained mice were centrifuged for varying periods ranging from 0.5 to 10 hr at 2.5, 5, and 10 x gravity. Liver glycogen and blood glucose levels increased significantly depending on the g load and exposure time. Adrenalectomy completely abolished the glycogen deposition response. The glycogen response was a critical function of the age of mice; unweaned mice did not respond. Blood corticosterone increased significantly prior to the deposition of glycogen. Centrifuged fed mice deposited three times the amount of glycogen of fasted mice. There was no significant difference in the amount of glycogen deposited in centrifuged mice previously starved for 1, 2, or 3 days. It is concluded that the increased glycogen deposited following centrifugation is effected by an increased elaboration of adrenal corticosterone.

AbstractObjectivesType 2 diabetes is a common metabolic disease and anxiety disorders are very common among diabetics. Buspirone is used in the treatment of anxiety, also having blood glucose-lowering effects. The aim of the study was to investigate the effects of buspirone on the glucose and lipid metabolism as well as vascular function in type 2 diabetic rats.MethodsA type 2-diabetic model was induced through a high-fat diet for eight weeks followed by the administration of low-dose streptozotocin (35 mg/kg, intraperitoneal) in rats. Buspirone was given at two different doses (1.5 mg/kg/d and 5 mg/kg/d) and combined with metformin (300 mg/kg/d). The fasting glucose and insulin levels, lipid profile were analyzed, and vascular response measured from the thoracic aorta was also evaluated.ResultsBoth doses of buspirone caused a significant improvement in fasting blood glucose levels. In particular, the buspirone treatment, combined with metformin, improved endothelial dysfunction and was found to be correlated with decreased nitrate/nitrite levels.ConclusionsBuspirone may be effective in the treatment of type 2 diabetes, either alone or in combination with other treatments, particularly in terms of endothelial dysfunction, inflammation and impaired blood glucose, and insulin levels.

In the present communication, synthetic somatostatin, a hypothalamic factor which has a known inhibitory effect on the release of growth hormone, thyroid-stimulating hormone, prolactin, insulin and glucagon in man and other mammals, was found to have an inhibitory effect on limb and tail regeneration in adult Diemictylus viridescens, when the newts were treated with a daily dose of 3·5 or 15 µg/animal for a period of 34 days post-amputation. At the higher dose, the animals exhibited total inhibition of appendage regeneration in a few cases and the remainder showed a considerable delay compared to the controls; none of the experimental animals reached the advanced four-digit stage achieved by the controls. Furthermore, the blood glucose and liver glycogen values in the somatostatin-treated animals were significantly lower than the control values. Mechanisms in the storage, mobilization and utilization of glucose (involving hormones) are discussed in relation to appendage regeneration in the newt and possible controls of regeneration at the level of the hypothalamus are suggested.
