The introduction of nucleic acids into cells has as a purpose of medical condition or disease. Currently, gene therapy studies a broad range of potential therapeutic interventions, including the body’s immune reaction to tumours, new blood vessels in the heart to alleviate heart attacks and to stop HIV-replication in patients with AIDS1 .There is also renewed emphasis on the gene therapy of genetic diseases, such as haemophilia A and B, and cystic fibrosis. Human gene therapy experimentation raises many issues. In this review article, background of gene therapy, introduction, genetic diseases, gene function, germ line gene therapy, hurdles in gene therapy, methods for gene therapy, ex vivo, in vitro and in vivo-gene therapy, risks associated with gene therapy, have been...

Plant is one of the important source of drugs that’s why we have done this project work to find out some biological activities of the plant exudates of Calotropis gigantea where antimicrobial, cytotoxic and antioxidant activity were analyzed. To test of antimicrobial activity, disc diffusion method has been followed. The exudate of the plant has shown antimicrobial activity against four microorganisms such as Escherichia coli (15mm), Vibrio mimicus (15mm), Vibrio parahemolytics (15mm)and Staphylococcus aureus (9mm). The exudates of the plant has shown cytotoxic activity which was done by following the brine shrimp lethality bioassay method. The result of the test has demonstrated good cytotoxic activity against Brine Shrimp Nauplii with a LC50 value of 12.66 µg ∕ml. The exudate of the plant has demonstrated good antioxidant activity with a LC50 value of 3.301 µg ∕ml..So from the project we can say that further investigation should be carried out to get the active...

Niosomes are non-ionic surfactant vesicles inclosing an aqueous phase and a wide range of molecules could be encapsulated within aqueous spaces of lipid membrane vesicles. They are microscopic lamellar structures formed on the admixture of a non-ionic surfactant, cholesterol and phosphate with subsequent hydration in aqueous media. Niosomes belongs to novel drug delivery system which offers a large number of advantages over other conventional and vesicular delivery systems. Namely they are the targeted drug delivery system which showing reduction of dose, stability and compatibility of non-ionic surfactants, easy modification, delayed clearance, suitability for a wide range of Active Pharmaceutical...

Some plants are toxic to living beings including humans, and are widely used all over the world in the treatment of various types of body ailments in traditional medicine, especially in the developing countries, due to theirs economic, social and cultural conditions. These plants are routinely taken for the nourishment of the pregnant women. This may cause the toxicity to the developing foetus, known as teratogenicity effect, and the plants are qualified as teratogens. Fenugreek is one of these plants, which has a wide range of medical applications, and wide use by ladies during pregnancy for different reasons. This Paper aims to present an overview of some existing studies and status of the teratogenic effect of fenugreek, to benefit from their results and...

The objective of the current study was to develop and validate simple and precise UV Spectrophotometric method for estimation of Diclofenac Sodium in the swab samples to validate cleaning procedure. The swabbing procedure was optimized in order to obtain a suitable recovery from stainless steel surface using Tex wipe polyurethane swab stick. Detection wavelength selected was 267 nm. The proposed method was validated in terms of Linearity, precision, accuracy, limit of detection and limit of quantitation. Linearity was studied over concentration range of 0.5 -3 μg / ml and correlation coefficient was found to be 0.999 for regression line. A recovery obtained was 94.58 %. LOD and LOQ for developed method were found to be 0.014715 µg/ml and 0.044592 µg/ml...
