Answer to Question 1

ANS: A
Infections caused by bacteria such as toxoplasmosis can result in granuloma formation. Degranu-lation is a part of mast cell destruction. Blood clots are not expected with chronic inflammation. Exudate production is pus formation.

Answer to Question 2

ANS: D
Macrophages secrete transforming growth factor-beta to stimulate fibroblasts to secrete the col-lagen precursor procollagen. Angiogenesis factor supports the growth of new vessels. Matrix metalloproteinase remodels proteins at the site of injury. Vascular endothelial growth factors are also involved in vessel growth.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
