To determine whether melatonin receptors (MR) exist in human stomach, specific binding of melatonin receptor in human stomach was measured by radioligandbindingassay.
为明确人体胃组织是否存在褪黑素受体(MR)，应用放射配体结合法检测人体胃组织MR特异结合量。

Methods: receptorradioligandbindingassay, receptor DNA binding assay and immunofluorescence methods were used.
方法：采用受体放射配基结合分析、受体- DNA结合分析及免疫荧光技术。
