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
Objective To evaluate the efficacy and safety of prostatic arterial embolization (PAE) and transurethral resection of prostate (TURP) in treatment of benign prostatic hyperplasia (BPH).Methods Totally 40 patients with BPH from Jan 2016 to Oct 2016 were selected.All patients were divided into PAE (n=20) and TURP (n=20) group by random number table method.The curative effect indexes (international prostate symptom score [IPSS],quality of life score [QOL],prostate volume [PV],postvoid residual [PVR],maximum urinary flow rate [Qmax] and prostate-specific antigen [PSA]),the complications and side effects,as well as the incidence of sexual dysfunction were analyzed and compared between the two groups.Results No statistical difference of IPSS,QOL,PV,PVR,Qmax nor PSA was found between the two groups before operation (all P＞0.05).IPSS,QOL,PV,PVR and PSA were significantly lower than those before operation 3,6 and 12 months after operation (all P＜0.05),while Qmax was obviously higher than that before operation (P＜0.05).Three months after operation,the curative effect indexes were statistically different between the two groups (all P＜0.05),while no statistical difference was found 6 and 12 months after operation (P＞0.05).The incidence of postoperative complications in TURP group was higher than that in PAE group (x2 =4.329,P=0.037).There was no statistical difference in the incidence of sexual dysfunction between the two groups (x2=2.105,P=0.147).Conclusion PAE and TURP can significantly alleviate clinical symptoms of patients with BPH.Three months after operation,the efficacy of TURP is better than PAE,but PAE is more minimally invasive and has fewer complications.
