Highly Active Antiretroviral Therapy-silver Nanoparticle Conjugate Alleviates Anxiety-like Behaviour in Streptozotocin-induced Diabetic Rats

Abstract Background: The inception of highly active antiretroviral therapy (HAART) has changed the management of human immunodeficiency virus (HIV) positive patients, and their life expectancy has improved. However, neurological complications associated with chronic HAART administration has not been fully addressed. Therefore, this study aimed to evaluate the potential benefits of silver nanoparticles (AgNPs) conjugates on the anxiogenic effects of HAART in type-2 diabetic rats. Methods: Forty-two (42) adult male Sprague-Dawley rats (250 ± 13 g) were divided into non-diabetic and diabetic groups. After induction of diabetes, non-diabetic and diabetic animals were administered either with de-ionized water (DW), HAART (98.2 mg/kg, p.o) or AgNPs +HAART (24.5 mg/kg, i. p) for 8 weeks. Thereafter, metabolic biomarkers, oxidative injury, tissue inflammation, and behavioural changes were evaluated, while the prefrontal cortex was excised for neurochemical analysis. Results: The HAART-treated diabetic rats showed a significant increase in blood glucose level, number of faecal pellets, malondialdehyde (MDA), and pro-inflammatory cytokines (TNF-α, IL-1β) while locomotion, reduced glutathione (GSH), superoxide dismutase (SOD) activity, and PFC-GFAP positive cells were significantly reduced compared with diabetic control. However, administration of AgNPs +HAART to diabetic rats significantly improved the blood glucose level, metabolic activities, SOD, GSH, PFC-GFAP positive cells while reducing MDA and anxiety-like behaviour in the open field test. Conclusion: Administration of HAART aggravates anxiety-like behaviours and promotes neurotoxic effects in the PFC of diabetic rats. However, AgNPs +HAART alleviates the 3 anxiogenic effects of HAART and preserves PFC-GFAP positive cells by reducing oxidative and neuroinflammatory injury.

Hyperglycaemia, a characteristic feature of diabetics mellitus leads to decreased antioxidant defense and hence the development of oxidative stress, which is involved in the aetiology of development of diabetic complications. This work was therefore aimed at evaluating the anti diabetic and antioxidative potential of the plant. These evidences suggest that good glycemic control and/or use of antioxidants may play an important role in the prevention of complications associated with diabetes. Diabetes was induced with single Intra peritoneal injection of alloxan (160 mg/kg b.w) dissolved in freshly prepared citrate buffer (pH 4.5). Oral administration of Kingelia africana (500 mg/kg b.wt) of methanol leaves and fruits extracts resulted in significant (p>0.05) decrease in the blood glucose level, MDA, glycosylated haemoglobin, lipid profiles and liver maker enzymes with corresponding increase in SOD activity, catalase activity, glutathione activity, serum protein concentration, and Vit.C concentration. In conclusion, K. africana possessed antioxidative properties evidenced by decrease blood glucose level and its effect on some oxidative parameters of diabetic rats.

Background. The application of nanomedicine to antiretroviral drug delivery holds promise in reducing the comorbidities related to long-term systemic exposure to highly active antiretroviral therapy (HAART). However, the safety of drugs loaded with silver nanoparticles has been debatable. This study is aimed at evaluating the effects of HAART-loaded silver nanoparticles (HAART-AgNPs) on the behavioural assessment, biochemical indices, morphological, and morphometric of the hippocampus in diabetic Sprague-Dawley rats. Methods. Conjugated HAART-AgNPs were characterized using FTIR spectroscopy, UV spectrophotometer, HR-TEM, SEM, and EDX for absorbance peaks, size and morphology, and elemental components. Forty-eight male SD rats ( 250 ± 13 g) were divided into nondiabetic and diabetic groups. Each group was subdivided into ( n = 8 ) A (nondiabetic+vehicle), B (nondiabetic+HAART), C (nondiabetic+HAART-AgNPs), D (diabetic+vehicle), E (diabetic+HAART), and F (diabetic+HAART-AgNPs). Morris water maze, Y-maze test, and weekly blood glucose levels were carried out. Following the last dose of 8-week treatment, the rats were anaesthetized and euthanized. Brain tissues were carefully removed and postfixed for Nissl staining histology. Results. 1.5 M concentration of HAART-AgNPs showed nanoparticle size 20.3 nm with spherical shape. HAART-AgNPs revealed 16.89% of silver and other elemental components of HAART. The diabetic control rats showed a significant increase in blood glucose, reduced spatial learning, positive hippocampal Nissl-stained cells, and a significant decrease in GSH and SOD levels. However, administration of HAART-AgNPs to diabetic rats significantly reduced blood glucose level, improved spatial learning, biochemical indices, and enhanced memory compared to diabetic control. Interestingly, diabetic HAART-AgNP-treated rats showed a significantly improved memory, increased GSH, SOD, and number of positive Nissl-stained neurons compared to diabetic-treated HAART only. Conclusion. Administration of HAART to diabetic rats aggravates the complications of diabetes and promotes neurotoxic effects on the experimental rats, while HAART-loaded silver nanoparticle (HAART-AgNP) alleviates diabetes-induced neurotoxicity.

Abstract Background Diabetes, a global cause of mortality in developing countries is a chronic disorder affecting the metabolism of macromolecules and has been attributed to the defective production and action of insulin characterized by persistent hyperglycemic properties. This global disorder harms organs of the body such as the liver, kidney and spleen. Medicinal plants such as Hunteria umbellate have been shown to possess hypoglycemic, antioxidative and anti-diabetic properties owing to the high concentration of active phytochemical constituents like flavonoids and alkaloids. The present study seeks to evaluate the hypoglycemic activities of ethanolic seed extract of Hunteria umbellate on streptozotocin-induced diabetes rats. Methods Thirty (30) female experimental rats were randomly divided into five groups with six rats per group and were administered streptozotocin (STZ) and Hunteria umbellate as follows. Group 1 served as control and was given only distilled water, group 2 rats were administered 60 mg/kg STZ; Group 3 was administered 60 mg/kg STZ and 100 mg/kg metformin; group 4 rats were administered 60 mg/kg STZ and 800 mg/kg Hunteria umbellate, group 5 rats 60 mg/kg STZ and 400 mg/kg Hunteria umbellate. The fasting blood glucose level of each rat was measured before sacrifice. Rats were then sacrificed 24 h after the last dose of treatment. Results The results showed that Hunteria umbellate significantly reversed STZ-induced increase in fasting blood glucose and increase in body and organs weight of rats. Hunteria umbellate significantly reversed STZ-induced decrease in antioxidant enzyme in liver, kidney and spleen of rats. Hunteria umbellate significantly reversed STZ-induced increase in oxidative stress markers in liver, kidney and spleen of rats. Conclusion Collectively, our results provide convincing information that inhibition of oxidative stress and regulation of blood glucose level are major mechanisms through which Hunteria umbellate protects against streptozotocin-induced diabketes rats.

Background Although hyper- and hypoglycemia induce neurophysiologic changes, there have been no reports on the effects of blood glucose changes on anesthetic requirements. This study examined the effects of hyper- and hypoglycemia on the minimum alveolar concentration (MAC) of halothane in rats. In addition, based on a previous finding that the level of brain acetylcholine was reduced during mild hypoglycemia, the authors examined the influence of physostigmine on MAC during hypoglycemia. Methods In Sprague-Dawley rats, anesthesia was induced and maintained with halothane in oxygen and air. The MAC was determined by observing the response to tail clamping and tested during mild hypoglycemia (blood glucose level, 60 mg/dl) and hyperglycemia (blood glucose level, 300 and 500 mg/dl) induced by insulin and glucose infusion, respectively (experiment 1). The effects of 0.3 and 1.0 mg/kg physostigmine given intraperitoneally on MAC were examined in rats with mild and severe hypoglycemia (blood glucose level, 60 and 30 mg/dl; experiment 2). Results In experiment 1, mild hypoglycemia significantly reduced the MAC of halothane (0.76 +/- 0.03%) compared with the control value (0.92 +/- 0.04%), but hyperglycemia did not change MAC. In experiment 2, mild and severe hypoglycemia reduced MAC of halothane in a degree-dependent manner. Physostigmine (1 mg/kg) had no effect on MAC regardless of blood glucose level, but 0.3 mg/kg reduced MAC. Conclusions Hypoglycemia reduced anesthetic requirements in a degree-dependent manner, whereas hyperglycemia had no effects. Although the mechanism of hypoglycemic MAC reduction needs further investigations, physostigmine studies suggest that this may not be related to inhibition of cholinergic transmission.

Pharmacodynamic Interaction

Background: Diabetes increases the risk of macrovascular complications and is often associated with angina in patient. Currently nicorandil, a potassium channel opener is being frequently used for the prevention and long-term treatment of angina pectoris. Glibenclamide exerts its antidiabetic action by closing the ATP sensitive potassium channels. Simultaneous use of nicorandil may antagonizes this action and may worsens the existing diabetes. To evaluate the pharmacodynamic interaction present study has been taken to study the effect of Nicorandil, a potassium channel opener on blood glucose level of alloxan induced diabetic rats and its pharmacodynamics interaction with Glibenclamide.Methods: Albino rats, weighing 150-200gm of male sex were used for the study. Diabetes was induced by injecting alloxan monohydrate 2% solution intra peritoneally in a dose of 150mg/kg body weight. Animal with Fasting Blood Sugar level between 250-300g/dl was selected for study and they were divided into 4 groups of 5 animals each. Group I- serving as control received 0.5ml normal saline orally for 28 days. Group II was given glibenclamide (0.5mg/kg body wt) for 28 days. Group III was treated orally with nicorandil (0.3mg/kg body wt) for 28 days. Group IV was given glibenclamide (0.5mg/kg) and nicorandil (0.3mg/kg) for 28 days. Fasting Blood Sugar level was recorded in all rats on 1st,3rd,7th,14th,21st and 28th day of the treatments.Results: results showed that glibenclamide significantly reduce blood sugar level (p <0.05) Wherase nicorandil showed rise in blood glucose level (p <0.05) While the combination (glibenclamide + nicorandil) showed rise in blood glucose (p <0.05) overall.Conclusions: Nicorandil worsen the existing diabetes and to be avoided or replaced with alternative drug in case of diabetes being treated with sulfonyl urease group of drugs.

Aims: To investigate the effect of food blends (plantain, soybean and ginger) on the blood glucose, lipid profile and haematological indices on streptozotocin induced diabetic rats. Methodology: A total of 35 rats of mean body weight 219.07 g separated into7 groups (5 per group) where induced by a single intraperitoneal (I.P) injection of streptozotocin (0.1 g dissolved in 5 ml of freshly prepared sodium citrate buffer 0.1 M, pH 4.5) at a dose of 40 mg/kg body weight after fasting for 12 hours and fed with flours/blends. The flours were produced from plant materials for different treatments/blends (blend A=100% unripe plantain, B=80% unripe plantain, 14% soybean, 6% ginger, C=70% unripe plantain, 26% soybean, 4% ginger, D= 60% unripe plantain, 38% soybean, 2% ginger, E= 50% unripe plantain, 50% soybean) and the phytochemicals and minerals content were determined. Blood glucose was determined at 5 days interval for 25 days. Diabetes was confirmed in rats with blood glucose concentrations >200 mg/dl. After 25 days rats were anaesthetized with chloroform vapour and blood samples collected by cardiac puncture for haematology and lipid profile determination. Results: The results showed that unripe plantain, soya beans and ginger in adequate proportion(C=70% unripe plantain, 26% soybean, 4% ginger or D= 60% unripe plantain, 38% soybean, 2% ginger) could help to reduce blood glucose, improve haematological parameters and lipid profile. Significant reduction was observed in the blood glucose level of rats fed blends C and D from 286 to 85 mg/dl and 307 to 90 mg/dl respectively at the end of experiment. These results also demonstrated that the inclusion of ginger at 6% causes rise in blood glucose level. Total cholesterol (TC) increased in all the blends. However, the lowest concentration of TC was observed in blends C and D. The highest packed cell volume (60%) and Haemoglobin (20 g/dl) level observed in rats fed blend C was significantly higher than the normal control fed conventional feeds. The increase in packed cell volume (PCV) (50%) and Hb (17 g/dl) in diabetic rats demonstrated that the formulated blend C was able to raise PCV and Hb above 50% and 17 g/dl (Normal control NC) respectively. Significant increase (P<0.05) in low density lipoprotein cholesterol (LDLc) was also observed in all the blends with blend C having the least (4.0 mg/dl) close to NC (2.0 mg/dl). Conclusion: From the results it is evident that blend C will manage and improve the health status of diabetic patients.

Diabetes is a chronic disease which characterized by hyperglycemia (elevated or abnormally high blood sugar levels) and other metabolic disturbances, including metabolism of lipids and haemostasis. Caesalpinia pulcherrima has previously showed strong anti-diabetic and hepatoprotective potential. The present research work was to investigate the anti-diabetic activity and hepatoprotective activity Caesalpinia pulcherrima in streptozotocin-induced (STZ) diabetic rats. The dose-dependent effects of 45days oral treatment with methanol extract of plant (200 and 300mg/kg) of CPAE on body weight, blood glucose level, total protein, albumin, liver marker enzymes and carbohydrate metabolizing enzymes were evaluated in STZ-induced diabetic rats. Oral administration methanolic extract of Caesalpinia pulcherrima of showed significant restoration of the body weight and decrease in the blood glucose level, liver marker enzymes (ALT, AST ALP) and carbohydrate metabolizing enzymes were observed in diabetic rats. These results suggest that fruit extract of Caesalpinia pulcherrima has valuable anti-diabetic activity in STZ-induced diabetic rats which is comparable to the standard drug metformin and hence might be of use in the management of diabetes.

Objective: The aim of the present study was to determine the effects of an olive tree extract with high polyphenols content on blood glucose level and other related parameters in streptozotocin-induced diabetic rats.Methods: Diabetes was induced in rats by intraperitoneal injection of streptozotocin (55 mg/kg bw). 72h after injection, rats with fasting blood glucose higher than 2 g/l were used for the experiments. Olive tree extract was administered for 28 d and blood glucose level was measured every 4 d. Total cholesterol, triglycerides, HDL-cholesterol, creatinine, urea, total protein, uric acid, aspartate aminotransferase and alanine aminotransferase levels, were determined at the end of the experiment.Results: The oral administration of olive tree extract contributes to blood glucose level decreasing in diabetic rats group, which was significantly lower at 4th week compared to the diabetic control rats. Moreover, supplementation by olive tree extract decreased significantly (p<0.05) the values of total cholesterol, triglycerides, HDL-cholesterol, creatinine, urea, total protein, uric acid, aspartate aminotransferase and alanine aminotransferase resulting from damage caused by streptozotocin treatment. Beside this, significant reduce (p<0.05) in heart disease risk ratio was observed for treated group (4.1±0.14) compared to untreated group (7.64±0.36), which was quite similar to normal rats (4.50±0.36). Studied olive tree extract effects were similar to those of glibenclamide, a well-known antidiabetic drug.Conclusion: Results herein obtained reveal the hypoglycemic effect of this olive tree extract, suggesting his potential use as a natural antidiabetic agent.
