Ficus Benghalensis

Neuropathic pain in diabetics is characterized by both hyperalgesia and allodynia. This is attributed to both uncontrolled glycemia and the further complications which it leads to. The objective of the study was to evaluate the neuroprotective effect of methanolic leaf extract of Ficus benghalensis against alloxan induced diabetic neuropathy in rats.Material and methods:Experimental diabetes was induced in wistar albino rats by single intraperitoneal injection of Alloxan monohydrate (150 mg/kg). The methanolic extract of leaves of Ficus benghalensis at a dose of 200 and 400 mg/kg body weight was administered at single dose per day to diabetes induced rats for a period of 28 days. Neuropathic pain was assessed in diabetic rats with various painful procedures. hot and cold water tail immersion test, pinprick test, cold allodynia, hot plate test, actophotometer and rota-rod tests were performed to assess the degree of thermal, mechanical, cold hyperalgesia and locomotor activity as well as motor co-ordination.Results:Animals treated with methanolic extract of Ficus benghalensis (200, and 400 mg/kg p.o.) showed good results in different parameters such as thermal allodynia (hot and cold), thermal hyperalgesia and motor co-ordination in comparison with diabetic control group. Thus, from this study we conclude that Ficus benghalensis exhibits significant neuroprotective activities against Alloxan-induced diabetic neuropathy in rats.

Background: Neuropathic pain is a very disturbing condition commonly found in diabetic patients. This study investigated xylopic acid (XA), the major constituent of Xylopia aethiopica in diabetic neuropathy as well as established possible toxicity of the compound on some selected tissues.Methods: Diabetes was induced in six groups of male rats with 120 mg/kg alloxan monohydrate. Diabetes was confirmed as a blood glucose level >15 mmol/dl. Neuropathic pain was confirmed on day three post-diabetes induction and treatment with 10 mg/kg, 30 mg/kg or 100 mg/kg xylopic acid, 10 mg/kg glibenclamide, 10 mg/kg morphine, and 10 ml/kg normal saline were initiated and continued for the next 15 days. The effects of the treatments on cold allodynia (cold water at 4°C) and thermal hyperalgesia (hot water at 55 ± 1°C) were evaluated within the duration of treatments. Histology of the liver and kidney, as well as haematological, serum biochemical, and semen analyses, were done after the fifteenth day of the experiment.Results: Xylopic acid produced significant anti-hyperglycaemic and analgesic effects in the cold allodynia and thermal hyperalgesia tests. Sperm motility, viability and count were significantly restored at 10 mg/kg XA as compared higher doses and negative control. The outcome of haematological analysis revealed a protective effect of XA although histological damage liver and kidney due to alloxan treatment was observable.Conclusions: Xylopic acid ameliorates diabetic neuropathy in rats and does not exert detrimental effects at low doses.

The plant Indigofera aspalathoides is a traditional medicine with tremendous therapeutic potential which finds it use in treatment of various ailments such as antibacterial, antioxidant, anti-inflammatory, antidiabetic, and anticancer activities. There are no reports that related to the use of this plant in treating patients with Alzheimer’s disease (AD). Hence present study was aimed to scientifically evaluate the neuroprotective effect of the methanolic extract of Indigofera aspalathoides against scopalamine induced Alzheimer’s disease in experimental rats using behavioral tests like elevated plus maze, Y-maze, and rota-rod tests. In addition to this, biochemical evaluation for acetylcholinesterase activity and histopathological evaluation of brain were done. The results suggests that methanolic extract Indigofera aspalathoides (200mg/kg B.wt and 400mg/kg B.wt) used in this study shows significant improvement of various behavioral parameters like locomotion, anxiety, memory, motor integrity and coordination etc when compared to control group. MEIA inhibited brain AChE enzyme, thereby elevating Ach concentration in brain homogenate and ultimately improved memory of rats. Further, more or less normal histological structure of the hippocampus and all amyloid plaques and neurofibrillary tangles that are formed under the influence of scopolamine disappeared in the rats pretreated with MEIA (200mg/kg B.wt and 400mg/kg B.wt). It can be concluded that our results strongly support the anti-Alzheimer’s potential of the methanolic extract of the plant I.aspalathoides and its use in traditional medicine.

Purpose: The present study aimed to assess functional and structural benefits of erythropoietin (EPO) when administered subconjunctivally in the retina of glaucomatous rats using electroretinography (ERG) and retinal thickness (RT) measurements. Methods: Glaucoma was experimentally induced in 26 Wistar Hannover albino rats. Animals were divided into 2 groups of 13 animals each: a treated group receiving a unique subconjunctival injection of 1,000 IU of EPO and a control group receiving a saline solution. In each group, 7 animals were used for retinal function evaluation (ERG) and 6 animals were used for retinal structural evaluation (histology). RT was measured, dorsally and ventrally, at 500 μm (RT1) and at 1,500 μm (RT2) from the optic nerve. Results: Retinal function evaluation: for both scotopic and photopic conditions, ERG wave amplitudes increased in the treated group. This increase was statistically significant (p < 0.05) in photopic conditions. Structural evaluation: for both locations RT1 and RT2, the retinas were significantly (p < 0.05) thicker in the treated group. Conclusion: Subconjunctival EPO administration showed beneficial effects both on retinal structure and on retinal function in induced glaucoma in albino rats. This neuroprotective effect should be applied in other animal species.

AbstractLittle is known about the role of 5-HT6 receptors in the pathophysiology of neuropathic pain. The aim of this study is firstly, to investigate the influence of spinal and systemic 5-HT6 receptors on thermal hyperalgesia, one of the most significant symptoms of neuropathy occurring in diabetes; and secondly to determine spinal lumbar serotonin and 5-HT6 receptor levels during development of diabetic neuropathy in mice. Diabetes was produced in Balb/c mice with a single injection of streptozocin (150 mg/kg, i.p.). Using the hot plate test, the 5-HT6 antagonist SB-258585 was given systemically (3, 10, 30 mg/kg) and intrathecally (0.01, 0.1, 1 nmol/mouse) to determine its effect on thermal hyperalgesia. Furthermore, on days 7 and 15 of diabetes, development of thermal hyperalgesia was evaluated in relation to changes in spinal serotonin and 5-HT6 receptor levels by using LC/MS/MS and Western blot analyses, respectively. Two-way analysis of variance and unpaired t-tests were used to evaluate data from hot-plate tests and 5-HT levels/ 5-HT6 receptor expression, respectively. Thermal hyperalgesia was observed in neuropathic mice, starting from day 5 after streptozocin administration. On day 15, systemic, but not intrathecal, SB-258585 attenuated thermal hyperalgesia in neuropathic mice. Spinal serotonin levels did not change during development of hyperalgesia after induction of diabetes, whereas spinal 5-HT6 receptor levels were significantly reduced on days 7 and 15. Our findings show that systemic, but not spinal, blockade of 5-HT6 receptors may exert antihyperalgesic effects in neuropathic mice and suggest that systemic 5-HT6 receptors contribute to the pathophysiology of diabetic neuropathy.

Background: Diabetic neuropathy is a complication of diabetes causing damage to the nerves. Objectives: Considering the neuroprotective anti-inflammatory antioxidant characteristics of statins, the current study aimed at determining the effects of atorvastatin on diabetic neuropathy through assessing the involvement of N-methyl-D-aspartic acid (NMDA) receptor, factors of oxidative stress, and inflammatory cytokines in rats with diabetes. Methods: Male rats were randomly assigned into six groups of the saline- and atorvastatin-treated controls, and streptozotocin (STZ)-induced diabetic animals treated with vehicle, diabetic animals treated with morphine (5 mg/kg), and rats treated with atorvastatin (10 mg/kg/day for 10 weeks) alone or in combination with NMDA receptor agonist. The hot plate and formalin tests were carried out on the rats. Moreover, malondialdehyde level, catalase and superoxide dismutase activities, levels of interleukin 1 beta (IL-1β), interleukin 6 (IL-6), and tumor necrosis factor alpha (TNF-α) in the dorsal root ganglia (DRG) of the animals were measured. Finally, the expression of the NMDA receptor in DRG was investigated in the current study. Results: Diabetes resulted in analgesia in all tests, and pretreatment with atorvastatin exacerbated diabetes-induced analgesic effects in the hot plate and early phase of the formalin test (P≤0.01 and P≤0.05 in comparison to those reported for the diabetic vehicle-treated group, respectively). The injection of NMDA could reverse the atorvastatin-induced analgesia in the hot plate test (P≤0.05). Diabetes caused to increase the levels of IL-1β, IL-6, and TNF-α in DRG in comparison to those reported for the control group (P≤0.05). Furthermore, the pretreatment of rats using atorvastatin could significantly reverse the increase in TNF-α level (P≤0.05). Conclusions: Atorvastatin showed analgesic properties, which might be acting through NMDA receptors and reduction of inflammatory cytokines.

Introduction: The pathogenesis of Parkinson’s disease (PD) is multifactorial in which oxidative stress, neuroinflammation, and mitochondrial dysfunction are the leading factors. Currently, the antioxidant and anti-inflammatory agents of natural sources as neuroprotectants have raised much attention. The current study aimed to explore the neuroprotective effect of methanolic extract of Sargassum wightii in male Wistar albino rats against rotenone-induced PD. Methods: The rats were administered with rotenone (10 mg/kg orally) daily for 28 days to induce PD. S. wightii (200 mg/kg and 400 mg/kg) and levodopa+carbidopa combination (10 mg/kg) were administered to different groups of rats one hour prior to rotenone for 28 days. Behavioral parameters (akinesia, tremor, motor coordination, and locomotor activities) and body weight were recorded on days 14th and 28th of drug treatment. On the 28th day, the animals were sacrificed for the neurobiochemical analyses of brain tissue. Results: Rotenone treatment caused a significant reduction in behavioural parameters (P < 0.001), neurochemical deficits (P < 0.001), and elevation of oxidative stress markers (P < 0.001) in the brain. Pre-treatment with S. wightii at 200 mg/kg and 400 mg/kg doses significantly attenuated the rotenone-induced behavioral alterations and restored the mitochondrial NADH dehydrogenase activity and dopamine level in the striatum (P < 0.001). Moreover, 400 mg/kg of S. wightii restored the rotenone-induced increased oxidative stress markers like malondialdehyde (MDA), superoxide dismutase (SOD), and reduced glutathione (GSH) in the striatum (P < 0.01). Conclusion: S. wightii has provided a neuroprotective effect, probably by virtue of its antioxidant and dopamine restoring potential. Hence, it may offer a promising and new therapeutic lead for the treatment of PD but needs further research.

Objective: The study is aimed to evaluate the antiparkinsonian effect of polyherbal formulation containing methanolic extract of Prunus amygdalus, Arachis hypogaea, and Citrullus lanatus (MEPAC) in chlorpromazine (CPZ)-induced Parkinson’s disease in Wistar albino rats. Methods: The antiparkinsonian activity of polyherbal formulation was studied in CPZ (3 mg/kg i.p.) induced Parkinson rat model. Rats were subjected to treatment with MEPAC and standard drug for a period of 21 days. The behavioral assessments, i.e., catalepsy and locomotor activity were assessed during the treatment period. Then animals were sacrificed, brains were isolated and homogenized for the estimation of biochemical parameters such as dopamine (DA), lipid peroxidation (LPO), glutathione (GSH), and superoxide dismutase (SOD). Histopathology of the brains was also done. Results: The cataleptic score of MEPAC (200 mg/kg and 400 mg/kg) treated rats was significantly reduced. On the other hand, there was improved in the locomotor activity. MEPAC (200 mg/kg and 400 mg/kg) treated rats showed increase in the level of DA, reduced GSH, SOD, and decreased LPO significantly. Conclusion: It may be concluded that methanolic extract of polyherbal formulation consisting of P. amygdalus, A. hypogaea, and C. lanatus showed a good antioxidant and neuroprotective effect in CPZ-induced Parkinson rats.
