Abstract:-Bioadhesion is the relatively new and emerging concept in drug delivery, Bioadhesion keeps the delivery system adhering to the mucus membrane. Transmucosal drug delivery systems show various merits over conventional drug delivery systems. Bioadhesive polymers facilitate the bioadhesion by their specific properties. In transmucosal drug delivery system, bioadhesive polymer plays major role along with active ingredients. Bioadhesive polymers that adhere to the mucin epithelial surface are effective and lead to significant improvement in drug delivery system. Improvements are also expected for other mucus-covered sites of drug administration. Bioadhesive polymers find application in the eye, nose, and vaginal cavity as well as in the GI tract, including the buccal cavity and rectum. This review focus on Bioadhesion, Important Factors of Bioadhesion, Ideal Characteristics, Classification, Description and Application of bioadhesive polymer.
Keywords:-Bioadhesion, Mucin, Rectum, Transmucosal drug delivery systems.

Abstract:-Many herbal remedies have been employed in various medicinal systems for the treatment and management of different diseases .The Indigofera Asplathoides commonly known as “Sivanar Vembu” has been recognized in different system of traditional medicines for the treatment of different diseases and ailments of human beings. This review supports all updated information on its pharmacognosy, pharmacological activity and traditional uses. Preliminary phytochemical screening of this plant revealed the presence of tannins, flavonoids, alkaloids, glycoside, and steroids. It has been reported as anticancer, antimicrobial, hepatoprotective, hypoglycemic, antioxidant, antibacterial, antiviral, anti-inflammatory, antineoplastic activity. The leaves, flowers and tender shoots of the plant were said to be cooling and demulcent and are employed as a decoction in leprosy and cancerous infections. There is no report available on isolated constituents of bioactive compound from whole plants Indigofera Aspalathoides which support its further to isolating a useful pharmacologically active compound as a drug.
Key words:- Indigofera Aspalathoides, Sivanar vembu, Pharmacognostical, Pharmacological, Traditional uses.

Abstract:- Twenty one Aspergillus wentii isolates were isolated from the soil samples were screened for L-glutaminase synthesis by plate assay method. Among the isolates the potential Aspergillus wentii SD4 were used for the synthesis in elevated level of L-glutaminase by optimizing the fermentation parameters like pH, temperature and inoculums size. The optimized pH will be 5.5 and it showed 1.71 IU. Temperature and inoculums sizes were also optimized as 350C and 1.0 ml (1x107). At this level these parameters shows 2.22IU and 2.73IU in elevated levels.
Key words: Aspergillus wentii, L-glutaminase, Fermentation kinetics, tumour inhibitor.

Abstract:-Urtica parviflora is considered as an important Medicinal plant, due to its various ethanomedical uses. Here, we analyze the Genetic Variation in U.parviflora, with respect to plant distribution in Kumaun hills based on change in altitude. Examination of Random amplified Polymorphic DNA (RAPD) markers from four plant samples collected at different heights from sea level indicated that genetic variation was appreciable, as samples from lower altitudes showed low genetic similarity with samples collected from higher altitudes. A total of 70 scorable bands were produced in four samples with 8 primers. The average number of bands per primer was 8.75. Out of 70 bands, 48 bands were polymorphic (68.75%) noted in the present investigation. The dendrogram of the samples showed two major clusters. The samples of Mukteshwar, Nainital and Bhowali are in one cluster and Bhimtal in other cluster.
Key words: Genetic Diversity, Primers, RAPD analysis, Taq DNA polymerase.

Abstract:- Started in 1970’s by cosmetic scientists, the research investigations in the field of niosomal vesicular systems are increasing exponentially with growing interest in these fields. The stream of these vesicles is still in its infancy, but the explosion of interest in niosomes as inherently active therapeutic agents, as vectors for targeted delivery of drugs, peptides and hormones and able to promote oral and transdermal drug delivery makes it timely to review current knowledge regarding various aspects of niosomes. Niosomes are non-ionic surfactant based vesicles formed from the self assembly of non-ionic amphiphiles in aqueous media resulting in closed bilayer structure which can entrap both lipophilic and hydrophilic drugs. The biocompatible and biodegradable nature makes them less toxic as compared to other vesicular systems. Lower cost of niosomes is attributed to greater availability of non-ionic surfactants. These properties make them versatile carriers and interesting candidate for study. The emphasis of this review is on potential of niosomes in drug delivery applications. The composition of niosomes and especially non-ionic surfactants are discussed in detail. Preparation methods are outlined separately for these vesicular systems. In addition, this article concentrates on the success in developing niosomes as potential carriers, in this millennium.
Key words: Non-ionic surfactants, Niosomes, Liposome, Drug delivery.
