The aim of the present study was to investigate the protective effects of Sesbania grandiflora flower (SGF) extract on erythrocyte membrane in Streptozotocin (STZ)-induced diabetic rats. Adult male albino rats of Wistar strain, weighing 190–220 g, were made diabetic by an intraperitonial administration of STZ (45 mg/kg). Normal and diabetic rats were treated with SGF, and diabetic rats were also treated with glibenclamide as drug control, for 45 days. In this study plasma insulin and haemoglobin levels were decreased and blood glucose, glycosylated haemoglobin, protein oxidation, lipid peroxidation markers, and osmotic fragility levels were increased in diabetic rats. Moreover, erythrocytes antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxide, glutathione reductase, glutathione-S-transferase, and glucose-6-phosphate dehydrogenase activities and non-enzymatic antioxidants such as vitamin C, vitamin E, reduced glutathione (GSH), and oxidized glutathione (GSSG) levels were altered. Similarly, the activities of total ATPases, Na+/K+-ATPase, Ca2+-ATPase, and Mg2+-ATPase were also decreased in the erythrocytes of diabetic rats. Administration of SGF to STZ-induced diabetic rats reduced blood glucose and glycosylated haemoglobin levels with increased levels of insulin and haemoglobin. Moreover, SGF reversed the protein and lipid peroxidation markers, osmotic fragility, membrane-bound ATPases activities, and antioxidant status in STZ-induced diabetic rats. These results suggest that SGF could provide a protective effect on diabetes by decreasing oxidative stress-associated diabetic complications.

Purpose The purpose of this study is to determine the effect of olive cake (OC) on lipid peroxidation as well as antioxidant enzymes activities of serum, red blood cells (RBCs) and liver, in streptozotocin (STZ)-induced-diabetic rat fed cholesterol-enriched diet. Design/methodology/approach Hypercholesterolemic male rats were rendered diabetic (HC-D) by a single intraperitoneal injection dose of STZ (35 mg/kg BW). HC-D rats were divided into two groups fed for 28d a diet supplemented with OC at 7.5 percent (HC-D-OC) or not (HC-D). A control group (C) was submitted to standard diet containing 20 per cent casein for the same experimental period. Findings RBCs, serum and liver thiobarbituric acid reactive substances (TBARS) contents were significantly increased in HC-D, compared to C group (p = 0.04, p = 0.02 and 0.03). These values were significantly decreased (48 per cent and 64 per cent; p = 0.02 and p = 0.0007) in serum and liver of HC-D-OC vs HC-D group. In RBCs, superoxide dismutase (SOD), catalase (CAT), and glutathione S-transferase (GST) activities were, respectively, 1.5, 2- and 1.7-fold higher (p = 0.03, p = 0.008 and p = 0.03) in HC-D group compared to HC group. In serum and liver, SOD, CAT and GST activities were, respectively, 1.3-, 2.6- and 1.6-fold increased (p = 0.03, p = 0.007 and p = 0.02). In HC-D-OC compared to HC-D group, RBCs glutathione peroxidase (GSH-Px), CAT and GST activities were, respectively, 2.1-, 3.3- and 2.1-fold higher (p = 0.04, p = 0.0009 and p = 0.03). In serum, SOD and CAT activities were, respectively, 1.5- and 1.9-fold increased (p = 0.02, p = 0.02). In liver, SOD, GSH-PX, CAT and GST activities were significantly increased (p = 0.005, p = 0.03, p = 0.02 and p = 0.04). Originality/value In diabetic rats-fed cholesterol-enriched diet, OC was able to reduce oxidative stress by decreasing lipid peroxidation and increasing antioxidant enzymes activities in serum, RBCs and liver.

Diabetes mellitus promoted an overproduction of free radicals and an increased incidence of both diabetic nephropathy and liver disease. In this report, we evaluated the effects of Chinese and Brazilian propolis on streptozotocin-induced hepatorenal injury in rats. The results demonstrated that Chinese propolis-treated rats had a 7.4% reduction in the glycated hemoglobin (HbAlc) level compared with untreated diabetic rats. Additionally, Chinese propolis induced an increase in the serum superoxide dismutase (SOD) level significantly while Brazilian propolis raised serum SOD and reduced level of malonaldehyde (MDA) and nitric synthetase (NOS). Of the measurable decrease in serum alanine transaminase (ALT), aspartate transaminase (AST) and microalbuminuria demonstrated the propolis-mediated improvement of hepatorenal function, which was further confirmed by histological examination. We also observed that Chinese and Brazilian propolis increased hepatorenal glutathione peroxidase (GSH-px) level and inhibited MDA production significantly. These results suggested that propolis may prevent hepatorenal injury by inhibiting lipid peroxidation and enhancing the activities of antioxidant enzymes.

Trigonella foenum-graecum seed powder (TSP) has been reported to have hypoglycemic and hyperinsulinemic action. The objective of the study was to examine the antidiabetic and neuroprotective role of TSP in hyperglycemiainduced alterations in blood glucose, insulin levels and activities of membrane linked enzymes (Na+K+ATPase, Ca2+ATPase), antioxidant enzymes (superoxide dismutase, glutathione S-transferase), calcium (Ca2+) levels, lipid peroxidation, membrane fluidity and neurolipofuscin accumulation in the diabetic rat brain. Female Wistar rats weighing between 180 and 220 g were made diabetic by a single injection of alloxan monohydrate (15 mg/100 g body weight), diabetic rats were given 2 IU insulin, per day with 5% TSP in the diet for three weeks. A significant increase in lipid peroxidation was observed in diabetic brain. The increased lipid peroxidation following chronic hyperglycemia was accompanied with a significant increase in the neurolipofuscin deposition and Ca2+ levels with decreased activities of membrane linked ATPases and antioxidant enzymes in diabetic brain. A decrease in synaptosomal membrane fluidity may influence the activity of membrane linked enzymes in diabetes. The present study showed that TSP treatment can reverse the hyperglycemia induced changes to normal levels in diabetic rat brain. TSP administration amended effect of hyperglycemia on alterations in lipid peroxidation, restoring membrane fluidity, activities of membrane bound and antioxidant enzymes, thereby ameliorating the diabetic complications.

Objective: Aerobic training and berberine chloride include antioxidant characteristics. In this study, aerobic training and berberine chloride intervention on the activity of antioxidant enzymes and lipid peroxidation of pancreatic tissue were investigated in type 1 diabetic male wistar rats. Materials and Methods: In the current study, 56 Wistar male rats were randomly assigned to seven different groups (n= 8), these groups include healthy control, diabetic control, Berberine-treated diabetes (15&30 mg/kg), aerobic training-treated diabetes, Diabetes treated with Berberine and aerobic training (15&30 mg/kg). The aerobic training schedule consisted of 6 weeks treadmills with a frequency of 5 sessions per week. The Berberine was also fed a specific dose every day and a half before training. The superoxide dismutase, glutathione peroxidase, catalase, and malondialdehyde were assessed using ELISA method. Results: The results showed that aerobic training, as well as the intervention of Aerobic Training and Berberine chloride, had a significant effect on the increase of antioxidant enzymes SOD and CAT in the pancreatic tissue groups (P-value< 0.05), but did not significantly affect the GPX level (P-value> 0.05). There was a significant decrease in MDA level in all treatment groups (P-value< 0.05). In diabetic groups that received both treatments at the same time, the MDA level more decreased (P-value< 0.0005). Conclusion: The aerobic training and berberine chloride concurrent intervention have a greater effect on the antioxidant enzymes in the pancreatic tissue of diabetic specimens. Therefore, it is recommended that aerobic training be done with berberine chloride.

Diabetes mellitus is a debilitating metabolic disorder and emerged as a major complication nowadays. The role of plants and their derivatives is indispensable in the treatment of various diseases. Azadirachta indica is a medicinal plant and holds a potential to attenuate the pathological changes associated with diabetes. In the present study streptozotocin (STZ) induced diabetic rats received the Azadirachta indica leaf extracts (ALE) treatment for a period of seven consecutive days (600 mg/Kg body weight) and then evaluated for changes in the liver tissue. The diabetic rats exhibited significant (p≤0.001) increase in the lipid peroxidation levels, decrease in GSH levels and modulation in the activities of various antioxidant enzymes including catalase, superoxide dismutase, glutathione peroxidase, glutathione reductase and glutathione-S-transferase. However, following ALE treatment to diabetic rats reported decrease in the blood glucose levels, lipid peroxidation levels, improved GSH levels and restored the activities of various antioxidant enzymes towards control levels. Besides this, light microscopic and ultramicroscopic examination of liver tissue also demonstrated less fragmentation, inflammation and decreased tissue level damage after ALE treatment, and corroborated the results of biochemical parameters. Thus, the results of present study revealed the hepatoprotective potential of Azadirachta indica in diabetes
