Eye is most unique organ of the body. Various drug delivery systems are used to deliver drug into eyes are used but there are various limitations of conventional systems so researchers are finding new ways by which contact time, bioavailability and residence time can be enhanced as well as patient discomfort and frequency of dose can be reduced. The conventional dosage forms are account for 90% of currently accessible ophthalmic formulations. The major problem encountered is rapid precorneal drug loss. To improve ocular drug bioavailability, there are significant efforts directed towards newer drug delivery systems for ophthalmic administration. Newer research in ophthalmic drug delivery systems is directed towards a combination of several drug delivery technologies, that includes to develop systems which is not only prolong the contact time of the vehicle at the ocular surface, but which at the same time slow down the elimination of the drug. In this review various new drug delivery systems applied in eye like inserts, in-situ gel, liposomes, niosomes, nanoparticles, iontophorosis, corneal shields,...

Holistic living is an art of living in harmony with nature and deals with a concern for the whole universe. The term holistic medicine is derived from the term “Holism” which means that a living being is not to be viewed as a composite of different organs but as an integrated entity viewed as a whole. The holistic concept takes into account individual’s physical, spiritual, nutritional and even social background. Holistic medicine is an intelligent combination best utilizing both streams i.e. while mainstream medicine is well suited for crisis intervention and alternative medicine is for health maintenance. Alternative medicine denotes a system of health care where combinations of healthcare systems are used instead of conventional or mainstream medicine to treat diseases. Alternative medical practices are based on a belief system and are not derived from modern science. But holistic medicine neither rejects conventional medicines nor comprises alternative practices. It is high time to recognize the emerging awareness, need and practice of Holistic and Integrated medicine. Drawing from various systems...

Aqueous extract of the fruits of the plant Piper longum was studied for their Anti rheumatoid activity in Freunds Adjuvant Induced Arthritis Rats with the dose of 200 and 400 mg/kg p. o. The administration of extract reported significant reduction in paw swelling on 4th, 8th, 14th and 21st day after sub-plenter administration of Complete Freunds adjuvant. The paw swelling was measured as a volume displacement using digital Plethysmometer. Furthermore, these results supported by radiographic analysis of affected knees of rats. From the results observed in the present investigation, it may be concluded that the aqueous extract of P. longum possesses potentially useful anti-arthritic activity in Complete Freunds Adjuvant...

Medicinal plants are a major source of therapeutic agents since time immemorial. Tribal and rural community from their parents on folklore medicines acquires incredible knowledge of phytomedicine in non-coded form. With the repeated discussions and consultations with Tribal and Bhumkas, we selected 36 different medicinal plants of 30 families used against enteric infections form Melghat forest (Amravati district). Antibacterial activity with extracts prepared in aqueous, ethanol, methanol, and acetone was performed by disk diffusion method against bacterial enteric pathogens such as E. coli, S. aureus, E. aerogenes, Ps. aeruginosa, S. typhi, S. typhimurium, S. paratyphi, Pr. vulgaris, K. pneumoniae and Sh. flexneri. Acacia arabica leaves proved strong antibacterial against E. coli, S. aureus, E. aerogenes, Sh. flexneri, S. paratyphi and S. typhi. In Terminalia chebula fruits and Terminalia bellirica fruits strong antibacterial potential was observed against E. coli, E. aerogenes, Ps. aeruginosa and S. typhimurium. Phytochemical analysis showed presence of fats, oils, alkaloids, cardiac glycosides, anthraquinones, tannins, and...

Soils generally contain adequate amount of inorganic and organic phosphorous but most of these remain unavailable to plants. The efficiency of water soluble phosphorus alone is usually low and soluble phosphorus when added to soil along with phosphate solubilizing microorganisms indicates utilization. The presence of soil microorganisms capable of transforming insoluble phosphorus to soluble form of phosphorus was studied Different phosphate dissolving bacterial strains are isolated from the rhizosphere soil of Costus plant and biochemical characterization and P2O5 uptake in liquid culture was...
