Our results are in concert with the experimental studies concerning the motility of E.coli cells. Capsazepine In addition, we show that our detailed model of chemotaxis is reducible to a non-homogeneous Markov process. ETHNOPHARMACOLOGICAL RELEVANCE Withania somnifera popularly known as Aswagandha or Indian Ginseng/Poison Gooseberry have thousands years of history of use in Indian traditional medicine. Besides, finding place root of the plant as Indian Ginseng, Ayurveda also uses root of this plant as general health tonic, adaptogenic, nootropic, immunomodulatory etc. With its widespread and growing use, it becomes prudent to scientifically evaluate and document both the efficacy and safety of this plant in humans. AIM OF THE STUDY Aswagnadha root is rapidly gaining popularity abroad for use as medicine. Current article attempts to primarily review the human efficacy and safety of Aswagandha generated through clinical trials. METHODS A systematic search both for indexed and non-indexed literature was made for W. somnifera using various search engines and databases and the details of research articles pertaining to all clinical trials/human studies, animal studies addressing safety issues of CNS, CVS, general toxicity, mutagety, memory/cognitive enhancement, obsessive-compulsive disorder, rheumatoid arthritis, type-2 diabetes and male infertility, and bears fertility promotion activity in females adaptogenic, growth promoter activity in children and as adjuvant for reduction of fatigue and improvement in quality of life among cancer patients undergoing chemotherapy. Properly designed, randomized-controlled, large-size, prospective trials with standardized preparations are needed to ascertain efficacy of Aswagandha root in previously studied and other new indications. ETHNOPHARMACOLOGICAL RELEVANCE As an important medicinal material constituting a variety of traditional Chinese medicine prescriptions, Nepeta angustifolia C. Y. Wu was used as a folk medicine to treat various vascular-related diseases including apoplexia, and cerebral haemorrhage in Tibet, China. Our previous studies have shown that this plant had a significant protective effect on vascular dysfunction of the intracerebral haemorrhage and diabetic rats. In present study, we aimed to investigate the protective effects and underlying mechanisms of Nepeta angustifolia on diabetic nephropathy (DN), a microvascular complication. AIM OF THE STUDY This study is aim to evaluate the protective effect of ethanol extracts of N. angustifolia (NA) on DN, and explore mechanism of action to provide basis for its pharmacological action against DN. MATERIALS AND METHODS High-fat diet and low-dose streptozotocin administration (HFD/STZ) induced diabetic rats were randomly divided into 5 groups (n = 8) the diabetic model groupl to maintain near normal body weight, blood glucose, urine volume, urine protein, kidney index and serum levels of Cr and BUN. NA treatment significantly improve renal dysfunction by the down-regulation of renal oxidative stress and pro-inflammatory mediators in HFD/STZ induced diabetic rats. In vitro experiments, NA has a significant cellular protective effect in H2O2-induced HBZY-1 cells, as well as the regulation in increases of SOD level and the decreases of ROS and MDA levels. Furthermore, NA treatment can significantly inhibit H2O2 induced mesangial cells apoptosis by the increasing mitochondrial potential and suppressing caspases-madiated signaling pathway. CONCLUSIONS NA has obvious improvement on renal dysfunction in HFD/STZ induced diabetic rats. NA can protect mesangial cells by inhibiting oxidative stress induced apoptosis, which may be related to its regulation of mitochondrial-caspase apoptosis pathway. At sub-anaesthetic doses, ketamine, a non competitive N-methyl-d-aspartate (NMDA) receptor antagonist, has demonstrated remarkable and rapid antidepressant (AD) efficacy in patients with treatment-resistant depression (TRD). However, its mechanism of action of ketamine is not fully understood. Since comorbid depression and anxiety disorders often occur, GABAergic/inhibitory and glutamatergic/excitatory drug treatments may be co-administered in these patients. Information regarding this combination is critical to establish efficacy or treatment restrictions to maximize translation from animal models to TRD patients, effectiveness and safety. To assess the specific role of excitatory/inhibitory neurotransmission in the medial prefrontal cortex-raphe nuclei (mPFC-DRN) circuit in the sustained antidepressant-like activity (AD) of ketamine (at t24h post dose), AMPA-R antagonist (intra-DRN) and GABAA-R agonist (intra-mPFC) were co-administered with ketamine (intra-mPFC). Twenty-four hours later, responses in the fomitant prescription of ketamine and BZD to see whether its sustained antidepressant activity is maintained in TRD patients. RATIONALE Methylenedioxymethamphetamine (MDMA) and methcathinone (MCAT) are abused psychostimulant drugs that produce adverse effects in human users that include hepatotoxicity and death. Recent work has suggested a connection between hepatotoxicity, elevations in plasma ammonia, and brain glutamate function for methamphetamine (METH)-induced neurotoxicity. OBJECTIVES These experiments investigated the effect of ambient temperature on the toxicity and lethality produced by MDMA and MCAT in mice, and whether these effects might involve similar mechanisms to those described for METH neurotoxicity. RESULTS Under low (room temperature) ambient temperature conditions, MDMA induced hepatotoxicity, elevated plasma ammonia levels, and induced lethality. Under the same conditions, even a very high dose of MCAT produced limited toxic or lethal effects. High ambient temperature conditions potentiated the toxic and lethal effects of both MDMA and MCAT. CONCLUSION These studies suggest that hepatotoxicity, plasma ammonia, and brain glutamate function are involved in MDMA-induced lethality, as has been shown for METH neurotoxicity. The toxicity and lethality of both MDMA and MCAT were potentiated by high ambient temperatures. Although an initial mouse study reported that several cathinones were much less toxic than METH or MDMA, the present results suggest that it will be essential to assess the potential dangers posed by these drugs under high ambient temperatures.
