Diabetes mellitus develops either due to insufficient insulin secretion or lack of insulin resulting from damaged pancreas beta cells. Dyslipidaemia is an acute complication in diabetes mellitus. The aim of this study was to investigate the extenuating effects of T. cattapa leaves and P. americana seed aqueous extracts on streptozotocin-induced lipids profile perturbation and pancreatic damage in experimental rats. Thirty male albino rats were randomly divided into six groups (n = 5). Group 1: (negative control), group 2: 80 mg/kgbwt streptozotocin (positive control), group 3: (80 mg/kgbwt streptozotocin + 200 mg/kgbwt T. catappa leave extract), group 4: (80 mg/kgbwt streptozotocin + 200 mg/kgbwt Persea americana seed extract), group 5: (80 mg/kgbwt streptozotocin + 200 mg/kgbwt extracts-mixture), group 6: (80 mg/kgbwt streptozotocin + 5 mg/kgbwt glibenclamide (standard drug). A single dose of streptozotocin was administered to the rats intraperitoneally; the extracts and glibenclamide were administered orally for 21 days, after which their pancreas was excised for histology. Thereafter, extracts of T. catappa leaves and P. americana seed on serum lipid levels imbalance in streptozotocin-induced diabetic rats were investigated. Histological studies showed a degenerative effect of the pancreatic islet cells of strotozotocin-induced groups. Results showed improvement in the regulation of lipid metabolism as well as the regeneration of the beta cells of pancreas on treatment with T. catappa leaves and P. americana seed. The extracts both equally exert significant antidyslipidemic effects in diabetic rats, in view of the extenuating effects of the extracts on pancreatic islet cells.

Background: There is a growing interest in the correlation between antioxidants and periodontal disease. In this study, we aimed to investigate the effect of oxidative stress and the impact of two antioxidants, curcumin and rutin, respectively, in the etiopathology of experimentally induced periodontitis in diabetic rats. Methods: Fifty Wistar albino rats were randomly divided into five groups and were induced with diabetes mellitus and periodontitis: (1) (CONTROL)—control group, (2) (DPP)—experimentally induced diabetes mellitus and periodontitis, (3) (DPC)—experimentally induced diabetes mellitus and periodontitis treated with curcumin (C), (4) (DPR)—experimentally induced diabetes mellitus and periodontitis treated with rutin (R) and (5) (DPCR)—experimentally induced diabetes mellitus and periodontitis treated with C and R. We evaluated malondialdehyde (MDA) as a biomarker of oxidative stress and reduced glutathione (GSH), oxidized glutathione (GSSG), GSH/GSSG and catalase (CAT) as biomarkers of the antioxidant capacity in blood harvested from the animals we tested. The MDA levels and CAT activities were also evaluated in the gingival tissue. Results: The control group effect was statistically significantly different from any other groups, regardless of whether or not the treatment was applied. There was also a significant difference between the untreated group and the three treatment groups for variables MDA, GSH, GSSG, GSH/GSSG and CAT. There was no significant difference in the mean effect for the MDA, GSH, GSSG, GSH/GSSG and CAT variables in the treated groups of rats with curcumin, rutin and the combination of curcumin and rutin. Conclusions: The oral administration of curcumin and rutin, single or combined, could reduce the oxidative stress and enhance the antioxidant status in hyperglycemic periodontitis rats.

AbstractWe previously reported that allogeneic, intraperitoneally administered “Neo-Islets,” composed of cultured pancreatic islet cells co-aggregated with high numbers of immunoprotective and cytoprotective Adipose-derived Stem Cells, reestablished, through omental engraftment, redifferentiation and splenic and omental up-regulation of Regulatory T-cells, normoglycemia in autoimmune Type-1 Diabetic Non-Obese Diabetic (NOD) mice without the use of immunosuppressive agents or encapsulation devices. Based on these observations, we are currently testing this Neo-Islet technology in an FDA guided Pilot Study (INAD 012-776) in insulin-dependent, spontaneously diabetic pet dogs by the intraperitoneal administration of 2×10e5 Neo-Islets/kilogram body weight to metabolically controlled (blood glucose, triglycerides, thyroid and adrenal functions) animals under sedation and local anesthesia and ultrasound guidance. We report here initial observations on the first 4 Neo-Islet-treated, insulin dependent pet dogs that are now in the intermediate-term follow-up phase of the study (> 6 months post treatment). Current results indicate that in dogs, Neo-Islets appear to engraft, redifferentiate and physiologically produce insulin, and are neither rejected by auto- or allo-immune attacks, as evidenced by (a) an absent IgG response to the allogeneic cells contained in the administered Neo-Islets, and (b) progressively improved glycemic control that achieves up to a 50% reduction in daily insulin needs paralleled by a significant fall in serum glucose levels. This is accomplished without the use of anti-rejection drugs or encapsulation devices. No adverse or serious adverse events related to the Neo-Islet administration have been observed to date. We conclude that this minimally invasive therapy has significant translational relevance to veterinary and clinical Type 1 Diabetes Mellitus by achieving complete and at this point partial glycemic control in two species, i.e., diabetic mice and dogs, respectively.

Objective: To determine the anti-hyperglycemic effects of interleukin-1 inhibitor (diacerein) in alloxan induced diabetic albino wistar rats. This experimental study was performed at the Department of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University, Tando Jam within 6 months from April 2016 to September 2016. Total of 160 adult Albino Wistar Rats having an average of 200 to 300 grams body weights were selected. Animals were categorized into 4 groups as; Group A (n=15): Control rats – receive 0.9% normal saline as placebo Experimental Groups Group B (n=15): Experimental Control (Diabetic rats) - Alloxan50 mg/kg body weight intraperitoneal. Group C (n=15): Diabetic rats + Diacerein (30 mg/kg/day) orally daily. Group D (n=15): Diabetic rats + Diacerein (50 mg/kg/day) orally daily. Animals were kept and treated as per the NIH Guideline for Use and Care of Laboratory Animals. Diabetes mellitus was induced via a single intraperitoneal injection of 50 milligram/kg alloxan monohydrated dissolved in aseptic 0.9% saline. After 72 hours, blood specimens were taken from the caudal vein of the rats and glucose level>200 mg/dL was taken as diabetes. Experimental rats were given diacerein approximately 30 and 50 mg orally for 6 weeks. At the completion of experiment the body weight was measured of each animal by electronic measuring balance and blood sample was taken from each animal of all groups to assess the blood glucose level and HbA1c level. Data were recorded via self-made proforma and analysis was done by using SPSS version 20. Results: Average body weight of Diabetic control (Group B) was 193.33±22.50 grams, which was lower in contrast to Diacerein treated group C 202.47±25.70 grams and significantly lower as compared to Diacerein treated group D as  212.6±23.43 grams. A significant increase in blood glucose levels 182.07±10.63 mg/dl was noted in the Diabetic control (Group B) compared to Diacerein treated group C (110.13± 8.54 mg/dl) and group D (85.87±8.41 mg/dl) (P=0.001). HbA1c was markedly raised in the Group B- diabetic controls, while diacerein treated diabetic rats (groups C and D) showed a significant decrease in HbA1c (P=0.001). Conclusion: It was concluded that Diacerein achieves the Euglycemic state by reducing the levels of blood glucose and glycated hemoglobin (HbA1c) in Alloxan-Induced diabetes mellitus in Wistar Albino Rats.
