Background: Diabetes mellitus (DM) affects the musculoskeletal system through its metabolic perturbations. Exercise modulates blood sugar levels and increases the body’s sensitivity to insulin in patients with DM. Objective: This study aimed to investigate the potential effects of combined quercetin and coenzyme Q10 (CoQ10) supplements with or without exercise on the histological, biochemical and molecular structures of diabetic rat’s skeletal muscle. Method: A total of 64 adult male albino rats were divided into six groups: control, trained nondiabetic, non-trained diabetic, diabetic rats treated with combined CoQ10 and quercetin, diabetic rats with treadmill training, and diabetic rats treated with treadmill training and CoQ10 and quercetin. Blood and skeletal muscle samples were obtained from all groups for routine histological examination and biochemical determination of cytokine levels and protein activities. Quantitative real-time polymerase chain reaction (qRT-PCR) and morphometric analysis of PAS and Bax expressions were also performed. Results: Biochemical analysis revealed improvement in all studied parameters with combined CoQ10 and quercetin than exercise training alone. Combined treatment and exercise showed significant improvement in all parameters especially interleukin 6 and malondialdehyde. Fibronectin type III domain-containing protein 5 (FNDC5) expression and irisin levels increased in all trained groups but combined treatment with exercise significantly increased their levels than exercise alone. Histological analysis revealed improvement after exercise or combined treatment; however, when exercise was combined with CoQ10 and quercetin, marked improvement was observed. Conclusion: the combination of CoQ10 and quercetin could be promising in preserving musculoskeletal function in patients with DM concomitantly with physical exercise.

Mortality And Morbidity

In the present study, combined treatment with etanercept and anakinra were tested in the streptozotocin-induced diabetic rats. Forty male Wistar albino rats were divided into 5 groups: healthy control (HC), diabetic control (DC), diabetic + anakinra (DAT), diabetic + etanercept (DET), and diabetic + etanercept + anakinra (DEAT). HC and DC groups received subcutaneous (s.c.) injection with a saline solution, while DAT and DET groups received anakinra (10 mg/kg per day, s.c.) or etanercept (10 mg/kg, twice a week, s.c.), and DEAT rats received both anakinra and etanercept treatments for 21 days after diabetes has developed. Anakinra and etanercept treatments significantly increased insulin and homeostatic model assessment β-cell function levels and decreased glucose levels compared to the DC group as single (DAT and DET) and combined treatments (DEAT). The thiobarbituric acid reactive substances level was significantly decreased in DAT group. The combine use of etanercept and anakinra can improve insulin and blood glucose in type 2 diabetic rats. The combined treatment of anakinra and etanercept together was more effective than single treatment and might have a potential new treatment strategy and to reduce the mortality and morbidity resulting from diabetes.

Two hundred and seven albino rats were injected subcutaneously with alloxan in doses varying from 140 to 200 mg. per cent per kilo of body weight. Fifty-nine animals which developed hyperglycemia (blood sugar levels above 150 mg. per cent) were observed for periods from 5 days to 32 weeks. Postmortem examination of the kidneys of these diabetic animals revealed glycogen deposition in the loops of Henle and convoluted tubules in 26 rats or 44 per cent. Glycogen could not be demonstrated in the glomeruli. Within the time limits of this experiment (32 weeks) no intercapillary glomerulosclerosis was observed. The following facts were revealed regarding glycogen nephrosis in alloxan diabetes: (a) Its appearance in the kidneys of the diabetic rats depended solely upon the terminal blood sugar levels of these animals. A value of 350 mg. per cent was the critical level, above which glycogen nephrosis was almost invariably demonstrable. With terminal levels below 300 mg. per cent no glycogen nephrosis was found. (b) No relationship existed between the postmortem finding of glycogen nephrosis and the initial blood sugar level, or the maximum height of the hyperglycemia attained by individual rats. (c) The results suggest that glycogen nephrosis is a reversible lesion.

Rheumatoid arthritis (RA) and its animal model adjuvant arthritis (AA) are inflammatory diseases characterized by chronic inflammation, systemic oxidative stress and disturbed mitochondrial bioenergetics of skeletal muscle. The present study aimed to evaluate the effects of coenzyme Q10 – CoQ10 (100 mg/kg b.w.), omega-3-polyunsaturated fatty acids – ω-3-PUFA (400 mg/kg b.w.) and their combined treatment in AA on impaired skeletal muscle mitochondrial bioenergetics, inflammation and changes in levels CoQ9 and CoQ10 in plasma. Markers of inflammation (C-reactive protein, monocyte-chemotactic protein-1), antioxidant capacity of plasma, respiratory chain parameters of skeletal muscle mitochondria and concentrations of CoQ9 and CoQ10 in plasma and in muscle tissue were estimated. Treatment of the arthritic rats with CoQ10, ω-3-PUFA alone and in combination partially reduced markers of inflammation and increased antioxidant capacity of plasma, significantly increased concentrations of coenzyme Q in mitochondria and improved mitochondrial function in the skeletal muscle. Combined treatment has similar effect on the mitochondrial function as monotherapies; however, it has affected inflammation and antioxidant status more intensively than monotherapies. Long-term supplementary administration of coenzyme Q10 and ω-3-PUFA and especially their combination is able to restore the impaired mitochondrial bioenergetics and antioxidant status in AA.

Nephroprotective Effect

Abstract Aim Oxidative stress due to chronic hyperglycaemia is a key factor in the development and progression of various microvascular complications including diabetic nephropathy (DN) and associated renal injury. Treatment with antioxidants is one of the strategies to protect the kidney from oxidative tissue damage to improve renal physiology during DN. The investigation, therefore, was designed to assess the nephroprotective effect of coenzyme Q10 (CoQ10) and N-acetylcysteine (NAC), either alone or in combination in streptozotocin (STZ)-nicotinamide (NAD) induced diabetic nephropathy (DN) in rats. Methods T2DM induced by STZ (55 mg/kg, i.p.)-NAD (110 mg/kg, i.p.) in Sprague-Dawley rats (220–250 g) was confirmed by the elevated blood glucose level and glycated haemoglobin. DN was assessed by renal function tests. The diabetic rats were treated with CoQ10 (10 mg/kg, p.o.) and/or NAC (300 mg/kg, p.o.) for 8 weeks after confirmation of DN. Oxidative tissue damage due to STZ-NAD was estimated by malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT), reduced glutathione (GSH), myeloperoxidase (MPO) and nitric oxide (NO) in the renal homogenate. Results Data showed significant alteration in serum and urinary creatinine, total protein, albumin, serum urea, blood urea nitrogen (BUN) and uric acid in diabetic animals as compared to the control rats. CoQ10 and/or NAC effectively alleviated the disturbances in renal function. Diabetic rats showed increased MDA, decreased SOD and CAT activities and decreased GSH along with a significant increase in MPO activity and nitrite content. Treatment with the aforementioned antioxidants and their combination ameliorated the kidney damage as indicated by the reduced OS with improved renal function. Conclusion The investigation suggests that the chronic hyperglycaemia-induced OS leads to the development and progression of DN. The combined treatment with CoQ10 and NAC has shown a remarkable nephroprotective effect suggesting that combined antioxidant therapy with CoQ10 and NAC may be useful in the attenuation of DN.

Diabetes mellitus has been a key degenerative disease affecting the world’s population. Lycopersicon esculentum (Tomato), a fruit consumed by many and known to have certain phytochemicals was used to determine its hypoglycemic effect on alloxan induced diabetic rats. The tomato was dried, pulverized and dissolved in distilled water and administered orally to albino rats in various concentrations according to their body weight. 30 albino rats were divided into 6 groups of 5 rats each. Groups I and II served as normal and diabetic control respectively, while groups III to VI were induced with diabetes and treated with different concentrations of the prepared tomato. After 14 days of treatment with various concentrations of tomato, there was a marked decrease in blood sugar levels at all the study concentrations. The result of the lipid profile a significant increase (p<0.05) in total cholesterol (150.67±7.02 mg/dL), triglyceride (159.33±5.03 mg/dL), LDL-Cholesterol (77.53±1.83 mg/dL) and a decrease in HCL-Cholesterol (51.67±1.00 mg/dL) levels in untreated diabetic rats when compared to the normal control. Upon treatment with 200 mg/kg of tomato, there was a significant decrease (p< 0.05) in the levels of Triglyceride, total cholesterol and LDL-cholesterol and an increase in the HDL-cholesterol. These results suggest that tomato may have the ability to reduce blood sugar level and the risk of cardiovascular disease.

Some investigators feel that insulin does not enter cells but exerts its influence in some manner on the cell surface. Ferritin labeling of insulin and insulin antibody was used to determine if binding sites of insulin to specific target organs could be seen with electron microscopy.Alloxanized rats were considered diabetic if blood sugar levels were in excess of 300 mg %. Test reagents included ferritin, ferritin labeled insulin, and ferritin labeled insulin antibody. Target organs examined were were diaphragm, kidney, gastrocnemius, fat pad, liver and anterior pituitary. Reagents were administered through the left common carotid. Survival time was at least one hour in test animals. Tissue incubation studies were also done in normal as well as diabetic rats. Specimens were fixed in gluteraldehyde and osmium followed by staining with lead and uranium salts. Some tissues were not stained.
