the present investigation was aimed at developing a novel colon targeted system of lornoxicam based on the use of a combination of ph dependent system (to prevent the premature release of drug in the upper git) and enzymatically degradation system (to ensure the specificity of drug release in the colon). the drug loaded guar gum microspheres prepared by emulsification cross-linking method were ...

Colon involvement in patients with severe acute or chronic pancreatitis have been seen, and complications such as paralytic ileus, segmental necrosis, pancreaticocolonic fistulas were reported. However, mechanical obstruction of the colon due to is very rare. We report a case transverse 43-year-old male, non-biliary necrotizing pancreatitis.
