Answer to Question 1

Answer: Chemotherapy for ALL is divided into several phases:
 Induction therapy phase: Reduce the disease to complete remission (i.e., eradicating the leukemic blast population).
 CNS prophylactic phase: Prevent CNS leukemia in young children. The two potential modes of treatment in the CNS prophylactic phase are cranium irradiation and/or intrathecal chemotherapy.
 Maintenance chemotherapy (cytoreductive therapy or remission consolidation therapy): Eradicate any remaining leukemic cells.

Answer to Question 2

Answer: The excessive proliferation of abnormal blasts that are present causes a crowding-out effect of normal hematopoietic cells. This leads to the following: frequent infections (because of low WBCs produced), fatigue, pallor, shortness of breath (from decreased RBCs produced), and bleeding and bruising symptoms (caused by decreased platelets produced).

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).
