Abstract:
Neuropathic pain represents a real clinical challenge because of its severity, chronic nature, and inadequate drug therapy. Recently, nitric oxide pathway has been proposed in the pathogenesis neuropathic pain like conditions. Curcumin is a well known for its antioxidant and medicinal values. The objective of the present study was to explore possible nitric oxide mechanism in the protective effect of curcumin against sciatic nerve ligation induced behavioral and biochemical alterations in rats.Sciatic nerve ligation was performed in Wistar rats. Various behavioral parameters (thermal hyperalgesia, cold allodynia) followed by assessment of biochemical parameters (lipid peroxidation, reduced glutathione, catalase, and nitrite) both on sciatic nerves and brain. Sciatic nerve ligation significantly caused thermal hyeralgesia, cold allodynia and oxidative damage as compared to sham (Sciatic nerve without ligation) and naïve animals. Chronic administration of curcumin (20 mg/kg, po) significantly reversed behavioral alteration and attenuated oxidative damage in both sciatic nerve and brain as compared to control.  Further, L-NAME (5 mg/kg) pretreatment with curcumin (10 mg/kg, po) potentiated protective effect of curcumin as compared to their effect per se. However, L-arginine (100 mg/kg) pretreatment with curcumin (10 mg/kg, po) significantly reversed the protective effects of curcumin. Result of present study suggests that nitric oxide mechanism could be involved in the protective effect of curcumin against sciatic nerve ligation induced behavior and biochemical alterations in rats.

ABSTRACT:
Pharmacovigilance is an important and integral part of clinical research. Pharmacovigilance is “defined as the pharmacological science relating to the detection, assessment, understanding and prevention of adverse effects, particularly long term and short term adverse effects of medicines. This addresses what exactly is pharmacovigilance?  What do we know of its benefits and risks, challenges and the future hold for pharmacovigilance in Indian medicine. Here the main focus on the aims and role of pharmacovigilance in medicines regulation and their Partners. This article describes and discusses the National programme of pharmacovigilance and centre in India. There role in collecting the reports ADRs of medicines. Further effectiveness and risk assessments of therapies are been discussed. The important role played by health care professional, pharmaceutical industries, media, and programmes carried by WHO. Finally the conclusion describes the major challenges and achievements for the future pharmacovigilance programme.

Abstract: Eclipta alba (L.) is small branched annual herbaceous plant with a long history of traditional medicines uses in many countries especially in tropical and subtropical regions. The herb has been known for its curative properties and has been utilized as antimytotoxic, analgesic, antibacterial, antihepatotoxic, antihaemorrhagic, antihyperglycemic, antioxidant, immunomodulatory properties and it is considered as a good rejuvenator too. Recent studies showed an antivenom property & corrosion pickling inhibitor action on mild steel in hydrochloric acid. A wide range of chemical compounds including coumestans, alkaloids, thiopenes, flavonoids, polyacetylenes, triterpenes and their glycosides have been isolated from this species. Extracts and metabolites from this plant have been known to possess pharmacological properties. This contribution provides an comprehensive review on ethnomedicinal uses, chemical composition, and the pharmacological profile as medicinal plant. Particular attention is given to antihepatotoxic, analgesic, antioxidant , antihyperglycemic, antiaggresive, wound healing properties and insecticidal effects presented in this review such that the potential use of this plant either in pharmaceutics or as an agricultural resource can be evaluated.

Abstract:
Wheatgrass has many characteristics desirable for health. It is known for its healing property. It is used as a cleansing and purifying agent and yet can be considered as a bodybuilder because of its nutritional value. It contains about 70% of chlorophyll which is very much comparable to alfalfa plant. Due to its high chlorophyll content it is also referred as Green Blood. Wheatgrass contain number of amino acids, vitamins, enzymes which contribute significantly to its health benefits. This article is nothing but an attempt to highlight one of the benefits of wheatgrass. The present investigation is undertaken in order to evaluate hypoglycemic property of wheatgrass juice.
