摘 要：
The research progress on classification of opioid receptors and introduced functions of four main types of receptors were summarized. In animal brains, changes in the opioid receptor number and their affinity to opioid ligands can affect opioidergic control of brain functions or central nervous control of endocrine system. In order to provide the references for changes of opioid receptors in pig brain, the ontogenic characterization of opioid receptors in pig brains was elaborated.
