Abstract: This study has shown that ApoA-l secretion in intestinal cells is constitutive; however, the rate of apoA-l secretion is increased by as high as 5-times the constitutive secretion rate when the cells are exposed to anti-inflammatory drugs such as aspirin and paracetamol. In contrast, pro-inflammatory drugs such as lipopolysaccharides and endotoxin appeared to decrease intestinal secretion of apoA-1. These results indicate that aspirin and paracetamol, two of the most widely used medications for fevers and headaches, may have beneficial effects on the metabolism of high-density-lipoproteins(HDL),the so-called" good cholesterol" by increasing the rate of apoA-1 secretion by the intestine. This may imply that the blood concentration of HDL may increase favorably should the amount of apoA-l increase as apoA-l is a major constituent of HDL. On the other hand, a bacterial infection in the intestine that leads to inflammation caused by bacterial lipopolysaccharides and endotoxin may have an adverse effect on intestinal secretion of apoA-l, thus there may be lowered blood concentration of HDL.
