Hydrophilic poly (ethylene glycol) capped poly (lactic-co-glycolic) acid nanoparticles for subcutaneous delivery of insulin in diabetic rats.

The aim of the present study is to evaluate the effect of insulin loaded poly(ethylene glycol) capped poly(lactic-co-glycolic)acid nanoparticles (ISPPLG NPs) by subcutaneous administration in diabetic rats. A series of biodegradable low molecular weight PLGA [90/10 (PLG2) and 80/20 (PLG4)] copolymers were synthesized by melt polycondensation and their ISPPLG NPs were synthesized by water-oil-water (W/O/W) emulsion solvent evaporation method. The PLGA copolymers and their nanoparticles were characterized.

Background: Emu oil is a product of animal origin used for the treatment of inflammation, burns etc. as a part of aboriginal medicine in Australia. Crohn's disease is a common inflammatory manifestation in humans and other animal species relating to the ulceration and digestive disturbances in upper gastro-intestinal tract.

Immunomodulatory activity of Punica granatum in rabbits--a preliminary study.

Punica granatum L. (Punicaceae) fruit rind powder (PGFRP) at the dose of 100 mg/kg orally as aqueous suspension was found to stimulate the cell-mediated and humoral components of the immune system in rabbits. PGFRP elicited an increase in antibody titer to typhoid-H antigen.
