The poor dissolution rate of water-insoluble drugs is still a major problem conforming the pharmaceutical industry. The most common method for improving the solubility is by increasing the surface area of the drug through micronization. But, in practice the effect of micronization is often disappointing, especially when the drugs are encapsulated or tablet. It is generally recognized that low solu...
ANTIOXIDANT, ORGAN PROTECTIVE AND AMELIORATIVE PROPERTIES OF METHANOL EXTRACT OF ANOGEISSUS LEIOCARPUS STEM BARK AGAINST CARBON TETRACHLORIDE- INDUCED LIVER INJURY
The methanol extract of the stem bark of Anogeissus leiocarpus was evaluated in vivo at 2.5mg/kg for antioxidant, hepatoprotective and ameliorative effect on hepatocellular injury following pre-treatment or post-treatment with carbon tetrachloride (CCl4). Levels of the lipid peroxidation product, malondialdehyde (MDA) or thiobarbituric reactive substances (TBARS) were taken as a measure of oxidati...
Incorporation of drugs into non-ionic surfactant vesicles (niosomes) during their manufacture affords a possible method of achieving controlled release. The aim of this study is to formulate niosomes as carriers for delivery of diclofenac sodium (DCS). Niosomes are prepared with a series of sorbitan monoesters (Span 20, 40, 60, and 80) and sorbitan tri-oleate (Span 85) and co-surfactants of polyox...
Arecanut seed has been used for medicinal properties more than 2000 years in South Asian countries. In fact, various pharmacological activities have been found in the arecanut seed extract or its constituents. Prevention of oxidative stress induced diseases is an urgent problem in all over the world. Traditional use of the plant for medicinal properties is to be documented for their possible us...
Niosomes are self assembled vesicles composed primarily of synthetic surfactants and cholesterol. They are analogous in structure to the more widely studied liposomes formed from biologically derived phospholipids. Niosomes represent an emerging class of novel vesicular systems. Niosome formation requires the presence of a particular class of amphiphile and aqueous solvent. In recent years a compr...
In recent time, scientific investigations of medicinal plants using indigenous medical systems has attracted a lot of attention globally. Nature has bestowed our planet with an enormous wealth of medicinal plants have been known for millennia and are highly esteemed all over the world as a rich source of therapeutic agents for the prevention and cure of diseases and ailments. Inflammation is compl...
HUMAN VAGINAL PATHOGEN INHIBITION STUDIES ON AQUEOUS, METHANOLIC AND SAPONINS EXTRACTS OF STEM BARKS OF ZIZIPHUS MAURITIANA
The aqueous, methanolic and saponin extracts of Zizyphus mauritiana barks has been screened for antimicrobial activities against some human vaginal pathogens Staphylococcus aureus, Pseudomonas aeruginosa, streptococcus facecalis, klebsiella pneumoniae, Escherichia coli, Enterobacter faecalis, Enterobacter faecium and Proteus mirabilis isolated from patient samples. Extracts were found to produce s...
PHYTOCHEMICAL COMPOSITION AND IN VITRO ANTIMICROBIAL ACTIVITY OF BAUHINIA RACEMOSA LAMK (CAESALPINIACEAE)
The aim of this study was to evaluate antimicrobial activity of the leaves of the Bauhinia racemosa L. In the current study, the aqueous and methanol extract of leaves of B. racemosa L. was tested against standard bacterial and fungal cultures. In vitro antimicrobial test was performed by agar well diffusion method on Mueller hinton agar and Sabouraud dextrose agar for bacterial and fungal culture...
Biosynthesis of nanoparticles is reviewed in detail in this study. Comparison of different synthesis methods, namely physical, chemical and green methods giving emphasis to biological synthesis is documented here. This study also details limitations of the present techniques and envisages the future scope of nanoparticle biosynthesis. Important applications of nanoparticles are also discussed brie...
Chromolaena odorata or siam weed is regarded as one of the most harmful weeds present on earth. Many efforts are being made for the control of this weed. But, none of them have provided any significant success. It has been utilized in the traditional medicinal systems for its curative properties for centuries. Some of the current studies have revealed its medicinal properties which have lead to an...
