title: The effect of paracetamol on naprosyn induced damage to gastric mucosa in albino rat.
abstract: The effect of paracetamol against ulcerogenic agent, naprosyn on the gastric mucosa of albino rat was observed under dissecting as well as laboratory microscope. Paracetamol in a dose of 250 mg/kg body weight provided protection against the ulcerogenic effect of naprosyn under dissecting microscope. Under laboratory microscope, a significant increase in the mucosal thickness with the administration of paracetamol followed by naprosyn was observed, while the flattening of the surface epithelium with slight exfoliation may be attributed to relative increase of pepsin from the chief cell. The increased secretory activity of the mucous neck cells in animals treated with paracetamol followed by naprosyn may be due to the increased bio-synthesis of prostaglandin from these cells which might have produced protective influence against the damaging effect of naprosyn.
