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.

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

The aim of the present study was to investigate the effect of oral melatonin administration on foetal growth retardation, utero-placental antioxidant enzymes activities and lipid peroxidation in experimental diabetic rats. Twenty pregnant rats were divided into four groups of five rats each. Diabetes mellitus was induced by a single intraperitoneal administration of 120mg/kg body weight of alloxan. From gestational day 5 to 19, 5mg/kg and 10mg/kg of oral melatonin were administered to the rats with clearly manifested gestational diabetes. On the 19th day of gestation, the rats were sacrificed by cervical dislocation and placental, foetal and uterine tissues were harvested for estimation of tissue glutathione peroxidase (GPx) activity and malondialdehyde (MDA) levels. Foetal weight, foetal size, placental and plasma glucose were also determined. Results showed that, in diabetic rats, foetal growth retardation was associated with a significant reduction in placental and uterine antioxidant enzymes (GPx) activities (P<0.001) and increased lipid peroxidation as evidenced by raised MDA concentration (P< 0.05). Treatment with oral melatonin significantly improved the foetal weight, placental and uterine antioxidant enzymes activities as well as reduced lipid peroxidation, without affecting the degree of hyperglycaemia. Effects of melatonin on foetal growth are presumed to be dependent on its ability to improve uteroplacental antioxidant enzymes activities and reduce lipid peroxidation.Bangladesh Pharmaceutical Journal 18(1): 42-47, 2015

The antihyperglycemic, antidiabetic, and antioxidant potentials of the methanolic extract of Garcinia pedunculata (GP) fruit in rats were investigated. The acute antihyperglycemic effect of different doses of GP was studied in normal male Wistar rats. Diabetes was induced by streptozotocin (STZ) injection in another cohort of male Wistar rats and they showed significantly higher blood glucose and glycated hemoglobin (HbA1c) levels, altered lipid profiles, and lower insulin levels compared to nondiabetic control animals. There were increased lipid peroxidation and reduced levels of cellular antioxidant enzymes in different tissues of diabetic rats. However, oral administration of GP extracts, especially the highest dose (1000 mg/kg), significantly ameliorated hyperglycemia (42%); elevated insulin levels (165%); decreased HbA1c (29.4%); restored lipid levels (reduction in TG by 25%, TC by 15%, and LDL-C by 75% and increase in HDL-C by 4%), liver and renal function markers, and lipid peroxidation (reduction by 52% in the liver, 39% in the kidney, 44% in the heart, and 46% in the pancreas); and stimulated tissue antioxidant enzymes to near normalcy. Overall, the findings suggest that GP fruit is effective against hyperglycemia and could be used in the treatment of diabetes and its complications and other oxidative stress-mediated pathological conditions.
