Objective. We aim to explore the effects and mechanisms of Jinlida granules on the dysfunction of hypothalamic-pituitary-thyroid (HPT) axis in diabetic rats induced by streptozotocin. Methods. A total of 48 SD rats were randomized into normal control group (NC, n=6) and diabetic group (n=42). Rats in diabetic group were randomly divided into diabetes mellitus (DM) control group, low, medium, and high doses of Jinlida group (JL, JM, and JH), medium dose of Jinlida plus Tongxinluo group (JM + T), metformin group (Met), and Saxagliptin group (Sax) (n=6 in each group). Diabetic rats were obtained by intraperitoneal injection of streptozotocin and sacrificed at 8 weeks to examine the function of HPT axis. Results. Levels of fasting blood glucose (P<0.05), pIκB, TNFα (P<0.05), pNF-κB, and IL-6 (P<0.01) in liver tissue and TSHR mRNA expression (P<0.01) in diabetic group were significantly increased, while levels of serum T3 and T4, thyroid hormone receptor (TR) mRNA and Dio1 mRNA in liver tissue, and sodium iodide symporter (NIS) mRNA in thyroid tissue in diabetic group were significantly decreased compared with those in NC group (P<0.01). Among diabetic groups, level of fasting blood glucose in JH, JM + T and Met group was lower (P<0.05) compared with DM group. However, levels of serum T3 and T4, TR mRNA in liver tissue, TSHR, and NIS mRNA in thyroid tissue in JH, JM + T, Met, and Sax group were significantly increased (P<0.01) compared to DM group. In contrast, levels of Dio1 mRNA, pI-κB in Met and JM + T groups, pNF-κB in JH, JM + T, and Met group, and TNFα and IL-6 in JM, JH, JM + T, and Met group were significantly decreased (P<0.05). HE staining showed reduced thyroid follicular epithelium and follicular area, as well as increased colloid area in DM group, indicating impaired synthesis, reabsorption, and secretory of TH in diabetes, which was significantly improved in JH, JM + T, and Met groups. Conclusion. HPT axis dysfunction in DM could be significantly improved by Jinlida granules. The mechanism might be associated with the anti-inflammatory effects involving NF-κB pathway. Our findings suggested the potential benefit of Jinlida granules for patients with HPT axis dysfunction and DM, which was to be verified by more experimental and clinical studies.

Hyperglycemia causes increased oxidative stress through an imbalance of reactive oxygen species and antioxidative mechanisms. It stimulates the production of inflammatory mediators and cytokines such as TNF-α, interleukin (IL)-1, and IL-18. Goat milk kefir and vitamin D3 have potential as antioxidants and anti-inflammatory agents that can repair damage to pancreatic β cells. This study analyzed the effects of goat milk kefir fortified with vitamin D3 on the IL-18 level in diabetic rats. An experimental randomized pre-post test with control group design was conducted on 20 male Wistar rats divided into four groups, namely negative control (K-), positive control (K+), treatment with unfortified kefir (P1), and treatment with kefir fortified with vitamin D3. The intervention lasted 34 days. Fasting blood glucose and IL-18 levels were measured before and after intervention. Blood glucose and IL-18 levels were analyzed using the glucose oxidase p-aminophenol method and enzyme-linked immunosorbent assay, respectively. No significant increase in the IL-18 level was found in the P1 group with a median of 56.5 (10–252.7) pg/mL to 148.2 (106.8–428.3) pg/mL (p = 0.465) or P2 group with a median of 117.3 (91.8–146.8) pg/mL to 246.7 (168.8–311) pg/mL (p = 0.068), and no significant increase was observed in blood glucose levels in the P1 group (366.9±134.8 mg/dL to 462.1±156.9 mg/dL, p = 0.357) or P2 group (415.0±203.8 mg/dL to 258±129 mg/dL, p = 0.463). Goat milk kefir fortified with vitamin D3 could maintain blood glucose and IL-18 levels.

Objective: The antihyperglycemic and antioxidative effects of L. microphyllum were evaluated by using in vivo methods in normal and alloxan induced diabetic rats.Methods: Diabetes was induced in Sprague Dawley rats by injecting alloxan through intravenous (i. v) at a dose of 100 mg/kg of body weight. Aqueous extract of L. microphyllum at different doses (400, 200 and 100 mg/kg of body weight) was administered orally (orogastric intubation) for 14 d. Blood glucose and oxidative stress markers were measured. Hematoxylin and eosin staining method were used to examine the pancreatic tissues.Results: At the 14 d interval, fasting blood glucose showed a reduction in serum glucose levels in animals pretreated with L. microphyllum compared with alloxan alone treated group. Oxidative stress was noticed in rat’s pancreatic tissue as evidenced by a significant decrease in glutathione level, glutathione reductase, glutathione-S-transferase, and catalase activities. Malondialdehyde showed a significant increase compared to the normal saline-treated control group. Serum biochemistry and oxidative stress markers were consistent with the pancreatic histopathological studies. Treatment of diabetic rats with L. microphyllum at a dose level of 100, 200 and 400 mg/kg body weight leaves extract for 14 d significantly prevented these alterations and attenuated alloxan-induced oxidative stress (P<0.05).Conclusion: The results of the present study indicated that the antihyperglycemic potential of L. microphyllum might be ascribable to its antioxidant and free radical scavenging properties. Thus, it is concluded that L. microphyllum may be helpful in the prevention of diabetic complications associated with oxidative stress.

Ocimum sanctum L. is widely used as traditional remedy to manage hyperglycemia. This study was aimed to evaluate the effect of aqueous-methanolic extract of O. sanctum leaves (OSE) on the anti-diabetic activity of gliclazide in alloxan-induced diabetes in Wistar rats. Diabetes was induced by intraperitoneally injecting alloxan (120 mg/kg b.w.) in rats. Treatments including OSE (100 mg/kg b.w.), gliclazide (100 mg/kg b.w.), and in combination were given daily to diabetic rats till the 21st day of study. Body weight and fasting blood glucose levels were determined at regular intervals, while blood and organ samples were taken at the end of the study for biochemical and histopathological studies. Results showed that treatments exhibited anti-hyperglycemic activity through significantly (p [ 0.05) restoring body weight, fasting blood glucose level, and serum levels of glucose, insulin and HbA1c. The anti-lipidemic activity was noticed as total cholesterol (TC), triglyceride (TG), high-/low density-lipoproteins (HDL-C, LDL-C) levels were restored in treated diabetic rats. Ameliorative effects of treatments were observed as significant (p [ 0.05) reduction in serum levels of liver function biomarkers (alanine aminotransferase; ALT, aspartate aminotransferase; AST, alkaline phosphatase; ALP and bilirubin; BIL) and restoration of oxidative stress biomarkers (catalase; CAT, superoxide dismutase; SOD and malondialdehyde; MDA) in liver tissue. Histopathological findings supported these results as an increase in pancreatic islets size and protective effects on liver tissue was observed in diabetic rats treated with gliclazide and OSE alone and their combination. Conclusively, the combination of OSE and gliclazide produced a synergistic anti-diabetic effect as compared to that of alone treatment.

The aim of this study was to determine whether diabetes enhanced the sensitivity of the myocardium to the deleterious effects of in vivo-administered Escherichia coli. Diabetes was induced in two groups of animals. One group received 70 mg/kg streptozotocin (iv) and exhibited a severe diabetes with elevated fasting and fed blood glucose concentrations and a markedly abnormal response to an oral glucose load. The second group received 45 mg/kg streptozotocin, was mildly diabetic (termed “latent” diabetes), and was characterized by normal fasting blood glucose but slightly elevated fed blood glucose and an abnormal response to a glucose load. A third group of rats received vehicle and served as time-matched control animals. Four weeks after induction of diabetes, all animals were catheterized under ether anesthesia and some received intraperitoneal injections of live E. coli. In vitro myocardial performance was assessed using the isolated, perfused working heart preparation. Ventricular function curves were generated by changing left atrial filling pressure and measuring changes in heart rate, cardiac output, and aortic peak systolic pressure. Cardiac performance in the severe diabetic group was depressed at the highest preload but was unchanged at lower preloads. Function in the latent diabetic group was not different from control. Sepsis induced a slight decrease in cardiac performance in the control group and resulted in larger reductions in the latent and severe diabetic groups. A depression in aortic flow was the major consequence of sepsis in the latent diabetic group, whereas decreased coronary flow was the primary change in the severe diabetic group.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract Background Diabetes and its related complications remain to be a major clinical problem. We aim to investigate the antidiabetic mechanistic actions of Plicosepalus Acaciae (PA) flowers in streptozotocin (STZ)-induced diabetic rats. Methods After diabetes induction, rats were divided randomly into five groups, including: 1) normal control group, 2) diabetic control group, 3) diabetic group treated with 150 mg/kg of ethanolic extract of PA flowers, 4) diabetic group treated with 300 mg/kg of ethanolic extract of PA flowers, and 5) diabetic group treated with 150 mg/kg of metformin. After 15 days of treatment; fasting blood glucose, glycated hemoglobin (HBA1c%), insulin, C-peptide, superoxide dismutase (SOD), catalase, reduced glutathione (GSH), malondialdehyde (MDA), triglyceride (TGs), total cholesterol (Tc), low density lipoprotein cholesterol (LDL-c), very LDL (VLDL), high DLc (HDL-c), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) levels were assessed. Histopathology of pancreas was also assessed. Results The results showed that PA flower ethanolic extract significantly reduced blood glucose, HBA1c%, MDA, TGs, Tc, VLDL, LDL-c, TNF-α, and IL-6 levels in a dose-dependent manner. All these parameters were already increased by diabetic induction in the untreated diabetic group. Treatment of diabetic rats with PA flower increased insulin, HDL-c, GSH, catalase, and SOD levels. Histological examination showed that the PA flower caused reconstruction, repair, and recovery of damaged pancreas when compared with the untreated group. Conclusions PA flower has a potential role in the management of diabetes as complementary and alternative therapy, due to its antioxidant, anti-inflammatory, hypolipidemic, hypoglycemic and insulin secretagogue effects.
