[The development of research on enzymes related to morphine-dependent].

The mechanism of morphine dependent is a complex Procedure. It involves in many complex mechanisms such as the ultra-structure of synapse of special brain areas, neurotransmitter, enzymology, and so on. These mechanisms have closely correlation. In this paper we reveiwed the development in enzymological mechanism of morphine dependent enzymes including protein kinase (PK), nitric oxide synthase (NOS), superoxide dismutase (SOD), adenylate cyclase (AC), Succinate dehydrogenase (SDH)and 3beta-Hydroxy steroid dehydrogenase (3beta-HSD).
