Neuroprotective Effects of Centella asiatica against Intracerebroventricular Colchicine-Induced Cognitive Impairment and Oxidative Stress

Oxidative stress appears to be an early event involved in the pathogenesis of Alzheimer's disease. The present study was designed to investigate the neuroprotective effects of Centella asiatica against colchicine-induced memory impairment and oxidative damage in rats. Colchicine (15 μg/5 μL) was administered intracerebroventricularly in the lateral ventricle of male wistar rats. Morris water maze and plus-maze performance tests were used to assess memory performance tasks. Various biochemical parameters such as lipid peroxidation, nitrite, reduced glutathione, glutathione-S-transferase, superoxide dismutase, acetylcholinesterase were also assessed. ICV colchicine resulted marked memory impairment and oxidative damage. Chronic treatment with Centella asiatica extract (150 and 300 mg/kg, p.o.) for a period of 25 days, beginning 4 days prior to colchicine administration, significantly attenuated colchicine-induced memory impairment and oxidative damage. Besides, Centella asiatica significantly reversed colchicines administered increase in acetylcholinesterase activity. Thus, present study indicates protective effect of Centella asiatica against colchicine-induced cognitive impairment and associated oxidative damage

Centella asiatica Attenuates D-Galactose-Induced Cognitive Impairment, Oxidative and Mitochondrial Dysfunction in Mice

D-galactose induced neurotoxicity is well known model for studying aging and related oxidative damage and memory impairment. Aging is a biological process, characterized by the gradual loss of physiological functions by unknown mechanism. Centella asiatica, Indian pennywort has been documented in the treatment of various neurological disorders including aging. Therefore, present study has been conducted in order to explore the possible role of Centella asiatica against D-galactose induced cognitive impairment, oxidative and mitochondrial dysfunction in mice. Chronic administration of D-galactose (100 mg/kg s.c.) for a period of six weeks significantly impaired cognitive task (both in both Morris water maze and elevated plus maze) and oxidative defense (Increased lipid peroxidation, nitrite concentration and decreased activity of superoxide dismutase, catalase and non-protein thiols) and impaired mitochondrial complex (I, II and III) enzymes activities as compared to sham group. Six weeks Centella asiatica (150 and 300 mg/kg, p.o) treatment significantly improved behavioral alterations, oxidative damage and mitochondrial enzyme complex activities as compared to contro l (D-galactose). Centella asiatica also attenuated enhanced acetylcholine esterase enzyme level in D-galactose senescence mice. Present study highlights the protective effect of Centella asiatica against D-galactose induced behavioral, biochemical and mitochondrial dysfunction in mice

A comparative study of effectiveness of local injection of autologous platelet rich plasma and injection corticosteroid solution in treatment of plantar fasciitis

Background: The heel pain is the most common problem worldwide and it was associated with plantar fasciitis (PF). The condition of treatment is very complex. Platelet-rich plasma (PRP) and injection of corticosteroids is the treatment of PF. This study was designed to access the effect of local PRP and local corticosteroid injection in PF patients.Methods: Sixty patients (between 29 to 60 years of age) with chronic PF were randomized prospectively in single tertiary care center in India. The study conducted from December 2013 to December 2015. All the patients were enrolled according to inclusion criteria and divided into two groups randomized. In group A (n=30) received PRP and group B (n=30) received corticosteroids injections. Visual analog scales (VAS) were filled by all the included patients. The follow-up scheduled at one and six months after complete enrolment of patients.Results: Between both the groups the significantly different observed at one and six months follow-up from the baseline. At one month follow-up significantly improvement in mean VAS score were observed in group B (p<0.001). At six months follow-up significantly improvement in mean VAS score were observed in group A (p<0.001).Conclusions: The present study concluded from the significance difference between both the groups proved promising form of treatment in chronic PF patients. Both the treatment was safe and effective in relieving pain improving function at different time period.
