Explanation / Answer
1)
a) Intake of food or milk with a drug reduces the risk of nausea and irritation of the stomach because the food neutralizes the acid produced in the stomach and the milk solubilizes the drug for its easy absorption. The solubilized drug quickly absorbed by the stomach and reduces the risk of nausea and irritation.
b) An individual taking large quantities of ASA (acetylsalicylic acid) need to be monitored for the presence of blood in the feces, because acetylsalicylic acid damage the liver and blood vessels, hence the feces may contain blood.
2)
Healing could be delayed in individuals taking glucocorticoids over a long period of time, because they inhibit the wound repair. Glucocorticoids (GCs) and diminishes the pro-inflammatory cytokines levels, for example IL-1, IL-6, and TNF- levels are reduced at the wound site.
4)
a) The stem cells can regenerate, the cells that cannot regenerate are: Nerve cells
