RESUMO

Objective To evaluate the safety of morphine hydrochloride injection. Methods Ear verin injection was used to evaluate the vascular irritation using the comparison of left side with right side in rabbits. Quadriceps femoris injection was used to evaluate the muscle irritation using the comparison of left side with right side in rabbits. Guinea pigs were intravenously injected with morphine hydrochloride injection at a dose of 2.8 mg·kg-1 once daily 3 times, stimulation was performed on 14 d after the last sensitization and the booster dose was 2 times the sensitization dose. The allergic reactions were observed. The different concentrations of morphine hydrochloride injection were placed in 2% rabbit erythrocyte suspension, and then the hemolyzation and agglutination were observed. Results There were no significant vascular or muscular irritation and injury effects of morphine hydrochloride injection in rabbits. There were no evidenceof hemolyzation and agglutination in rabbit erythrocytes in vitro. No allergic reactions on guinea pigs in vivo were observed. Conclusion After treatment of morphine hydrochloride injection, neither obvious vascular /muscle stimulation or sensitization, nor hemolyzation or agglutination appeared in rabbits. The research results provide basic reference for the clinical rational and safe application of morphine hydrochloride injection.

RESUMO

BACKGROUND:The OPG-RANKL-RANK transport system plays a crucial role in bone resorption mechanism of osteoclasts. OBJECTIVE:To observe the expression of OPG-RANKL-RANK signaling system in osteoclasts, osteoporosis, and the targeted therapy of OPG-RANKL-RANK signaling system. METHODS:We retrieved related literatures in the periodicals database with the key words of“osteoprotegerin, RANKL, RANK, osteoclasts, osteoporosis”in English and Chinese. According to the inclusion criteria, the literatures were included in this study after the evaluation of quality. RESULTS AND CONCLUSION:The mature of osteoclasts is mediated via OPG-RANKL-RANK signaling system and its associated signaling pathways. This signal pathway leads to the mechanism of osteoporosis. At the genetic and molecular levels, the targeted therapy of osteoporosis has become the focus. OPG-RANKL-RANK signaling system can provide a research platform for targeted treatment of osteoporosis, and OPG-RANKL-RANK signaling system is an important way to the regulation of osteoclasts and osteoporosis.
