Zinc is essential in the regulation of a variety of physiological and biochemical events in the organism. It plays a critical role in maintaining the cell membrane integrity, protein-carbohydrate-lipid metabolism, immune system, wound injury and in the regulation of a number of other biological processes associated with normal growth and development. Physiological and biochemical levels of many hormones are affected by zinc metabolism. Therefore, growth impairment, hypogonadism, and some endocrine diseases are associated with the deficiency of zinc...

The final quality of pharmaceutically active herbal preparation is significantly contributed by extraction procedures. Hence in the last decade Microwave assisted extraction (MAE) has been introduced. This is an efficient and modern tool with multiple benefits as compared to the traditional methods of extraction. The benefits are in terms of reduction in cost, time of extraction, amount of solvent used, energy consumptions and low CO2 emission. Therefore present study was planned to give brief overview on applications of microwave assisted extraction of natural products...

Drug induced adverse drug reactions is more common in long term therapy particularly in immune compromised patients. Most of the drugs causing dermatological reactions like skin rashes, pruritus, steven johnson syndrome and exfoliative dermatitis. Nevirapine is the first line drug for human immunodeficiency virus (HIV) infection from the category of non-nucleoside reverse transcriptase enzyme inhibitor (NNRTI). In the present cases, we have reported the nevirapine induced severe exfoliative dermatitis.

Apomorphine is a classical psychostimulant and used throughout the world as prescribed medicine. Despite of their therapeutic effects, use of psychostimulants is restricted because some psychosis and impulse control disorders are the consequence of their long term use. Studies suggest that serotonin (5-Hydroxytryptamine; 5-HT) has a critical role in psychosis and drug abuse. Center of the present article is to assess the impacts of serotonin in the easing of misuse potential; the sensitization prompted by recommended psychostimulant apomorphine...

Cananga odorata (Lamk.) Hook. f. et Thoms., belonging to Annonaceae, is an evergreen tree. The oils extracted from its flower are a famous perfume and used in daily chemical and food industry. Although this plant has been widely cultivated in tropical regions of the world, the yield of oils from its flower is very limited. In order to develop the other parts of this plant, the chemical constituents of the volatile oils from the leaves of C. odorata was analyzed by gas chromatography/flame ionization detector (GC-FID) and GC/mass spectrometry (GC-MS)...

New series of Co+2, Ni+2, Cu+2 and Zn+2 complexes have been synthesized using a bio-active hydrazone compound 4-hydroxybenzaldehyde-N-(5-chloro-2-oxo-1,2-dihydro-3H-indol-3-ylidene), abbreviated as [HL]. Complexes were characterized using elemental analysis, FT-IR, UV-visible spectroscopy conductivity and magnetic susceptibility measurements. Results showed that the bi-dentate [HL] coordinated in a square planner manner with Cu+2 while for the rest of the M+2 ions, it coordinated in a octahedral fashion. Free ligand and its metal complexes were also studied for their antioxidant potential by employing two methods i...

The antioxidant potential of leaf, stem, root and flower extracts of Quisqualis indica Linn. was assessed to verify its ethnopharmacological importance. Both polar and non-polar solvents like n-hexane, chloroform, ethanol and distilled water were used to obtain crude extracts. The chloroform extract of leaves showed the maximum %age yield, i.e. 27.3% while the n-hexane extract of stem showed the minimum yield, i.e. 0.2%. Five activities including DPPH free radical scavenging activity, ABTS+ assay, Total flavonoid components (TFC), Total phenolic components (TPC) and Metal chelating Assay (MC) were employed to evaluate the antioxidant activity of the plant...
