ABSTRACT
A study was conducted to determine the antibacterial and antifungal activitieswith minimum inhibitory concentration and cytotoxic activity of Momordica charantia (Family: Cucurbitaceae) leaves. In our present study, the antimicroial activity of n-hexane, chloroform and ethyl acetate fractions of the plant were investigated against a number of pathogenic Gram-positive (Bacillus megaterium, Bacillus subtilis, Staphylococcus aureus and Sarcina lutea), Gram- negative (Salmonella paratyphi, Salmonella typhi, Vibrio parahaemolyticus, Vibrio mimicus, Escherichia coli, Shigella dysenteriae, Shigella boydii and Pseudomonas aeruginosa) bacteria and three funguses (Candida albicans, Aspergillus niger and Saccharomyces cerevesiae). Here the zones of inhibitions for the test samples (500 µg /disc) werecompared with that of reference standard (30 µg /disc) in determining antimicrobial activity. All the extracts showed significant antibacterial and antifungal activities against all the pathogenic bacteria except A. niger. The highest sensitivity for n-hexane, chloroform and ethyl acetate fractionswas against gram positive bacteria B.cereus. Almost all the gram positive, gram negative bacteria and fungus were inhibited by ethyl acetate extract and showed better activity compared to n-hexane and chloroform extracts. All the three fractions were tested as antifungal against C. albicans and S. cerevesiae. They showed moderate activity against C. albicans whereas a very good activity against S. cerevesiae. But A. niger was not sensitive to the experimental extracts.Minimum inhibitory concentration (MIC) that is the lowest concentration at which the test sample shows its highest activity against microorganisms was tested by serial dilution method. The MIC for n-Hexane and chloroform extracts was against B. cereus (64 µg /ml).  The ethyl acetate extract exhibited antibacterial activity with MIC of 64 µg /ml against S. aureus, S. luteae, S. boydii, S. dysentereae and V. mimicus. The Brine shrimp lethality bioassay method was used to determine the cytotoxic activity and vincristine sulphate was used as positive control. The LC50 values of standard vincristine sulphate, n-hexane, chloroform and ethyl acetate extract were 10.18 µg /ml, 24.71 µg /ml, 19.02 µg /ml and 30.38 µg/ml respectively which indicate the presence of bioactive compounds present in the plant extracts are promisingly cytotoxic.

ABSTRACT:
Simple, sensitive and specific spectrophotometric method were developed and validated for quantification of CAPECITABINE (CAP) by difference spectroscopy. CAP exhibits a substantial difference in absorbance in the two solvents that is in 0.01 N HCL and 0.01 N NAOH at 295 nm. Beer’s law was obeyed in the concentration range of 1 to 20 µg ml-1for CAP. Results of tablet analysis showed standard deviation in the range of 98.42 to 101.95 % for CAP which indicate repeatability of the method. The results indicated excellent recoveries ranging from 98.45 to 101.70 % for CAP with a mean of 99.12 %. Recoveries obtained do not differ significantly from 100% showed that there was no interference from the common excipients used in the tablet formulation indicating accuracy and reliability of the method.

ABSTRACT
Non-ionic surfactant vesicles (Niosomes or NSVS) are widely studied as an alternative to hydrated surfactant monomers. Non-ionic surfactants of wide structural types have been found to be useful alternatives to phospholipids in fabrication of vesicular system. They are the microlamellar structures formed by the mixing of Non-ionic surfactant of alkyl or dialkyl polyglycerol ether class and cholesterol with subsequent hydration in aqueous media. This review article deals with the detailed use of Niosome as novel drug delivery system for ophthalmic use, since this route is most frequently used for the treatment of eye infection.

ABSTRACT
With the advent of modern times, stress and pollution have led to major effect on rise of death toll due to chronic diseases. Such diseases are major cause of concern for the medical society. Lycopene, a carotenoid pigment found in tomatoes and its products has antioxidant properties due to the presence of numerous double bonds. Increased consumption of lycopene containing diet has been proposed to offer a protection against many types of cancers and cardio-vascular diseases. Its potential role as nutraceutical has been suggested in many studies. The present review deals with fundamental biochemistry, bio-availability and benefits of lycopene rich diet and its relation with some chronic diseases like various forms of cancers and cardiovascular diseases.

ABSTRACT
The present research aims to investigate the antibacterial and antioxidant activities of different leaf extracts of Aquillaria malaccensis. Antibacterial tests were done by Disc diffusion method using Kanamycin as standard. The chloroform extract showed good antibacterial activity against Shigella boydii and Escherichia coli with 19 mm and 17 mm zone of inhibition respectively. All other extracts showed mild to moderate antibacterial activity against other bacteria with 7 – 16mm zone of inhibition. The antioxidant activity of the extracts was determined by using DPPH spectrophotometrically and ascorbic acid was used as standard. All three extracts showed significant antioxidant activities having IC50 value of 38.96 µg/ml, 39.63 µg/ml and 64.75 µg/ml for ethyl acetate, n –hexane and chloroform extracts respectively.

ABSTRACT
Polycystic Ovarian Syndrome is one of the most common female endocrine. Many papers reported the correlation between infertility that most eminently predisposes towards cancer in PCOS women from many years. From both clinical and experimental research one can conclude that correlation between PCOS and endometrial cancer is the strongest. Most studies on correlation between PCOS and ovarian cancer as well as breast cancer failed to show a link though Pulsatilla have a strong effect on it. Various synthetic drugs which mainly used in the treatment of PCOS and endometrial cancer but here the problem is those drugs has lots of side effect/Adverse effect so we should go with the natural product Pulsatilla Sp. Which is used on PCOSand various cancer. Pulsatilla is a well establish drug for PCOS with unknown mechanism of action. Deoxypodophyllotoxin, which was isolated from the roots of P. koreana, was found to inhibit the tube-like formation of HUVECs (human umbilical venous endothelial cells) and have a potent antitumor effect. The chemical constituent saponin D present in Pulsatilla root is responsible for the anti tumor activity. The results, which are expressed as Pulsatilla saponin D has such a potent antitumor effect (IR, 82 %) on a solid tumor, which is higher than Adriamycin (IR, 64%). 23-Hydroxybetulinic acid synthesized from Pulsatilla chinensis also shows anti tumoral activity. Though the potency of pulsatilla sp. Are less than synthetic marketed drugs but by structural modification we may get potent anti canceral agent with least toxicity by Pulsatilla.

ABSTRACT:
The main objective of this work is to formulate gastroretentive floating microspheres of hydrochlorothiazide and to study the effect of formulation variables like drug to polymer ratio and concentration of polymer dispersion. The hydrochlorothiazide floating microspheres were formulated by using orifice-ionic gelation technique. These microspheres were formulated by using sodium alginate as sustained release polymer, sodium bicarbonate as gas generating agent and calcium chloride as a cross linking agent. The rheological properties of the polymer dispersion were studied. The microspheres were formulated by different drug to polymer ratio’s at various concentrations of sodium alginate dispersion. Thus formulated microspheres were evaluated for floating behaviour, drug entrapment efficiency, drug content, micromeritic properties, particle size, swelling index, invitro drug release studies and release kinetics. The better formulation was subjected for stability studies and SEM analysis. The effect of formulation variables on the entrapment efficiency and release rate constant was studied by statistical analysis. The hydrochlorothiazide microspheres formulated with 1:3 drug to polymer ratio and 3.5% sodium alginate dispersion concentration was selected as optimized formulation based on the results.
