Thrombolytic therapy or percutaneous coronary intervention for myocardial infarction often cause myocardial ischemia/reperfusion injury (MIRI) and poor prognosis of patients. This study aimed to explore the protective effect and potential mechanism of hydromorphone hydrochloride (HH) on MIRI. Fifty Sprague-Dawley male rats were randomly divided into Sham group, I/R group, HH-pre group, HH-post group, and HH-pre + post group.

Methods: A rat I/R model was established by ligating the left anterior descending coronary artery.
Morphine is generally used to treat chronic pain in clinic. But long-term use of morphine can inevitably induce analgesic tolerance and hyperalgesia. Caveolin-1 is reported to affect morphine-mediated signaling transduction.

Objective of this study was to investigate the sedative and hypnotic effects of palmatine and to observe whether its mechanism is related to 5-hydroxytryptamine (5-HT) and GABA. The sedative and hypnotic effects of palmatine on mice were observed with mouse autonomic activity test, direct sleep test, pentobarbital sodium in suprathreshold and subthreshold dose sleep test. The content of GABA and 5-HT in brain homogenate was determined by ELISA method.
