ABSTRACT
Objective:To investigate the clinical application and adverse events of vinpocetine injection. Methods:The application of vinpocetine injection in the patients in neurology department during December 2013 and December 2014 in a hospital was statistically analyzed. The adverse reactions of the injection reported in the professional literatures and relevant documents were also retrieved and statistically analyzed. Results:The infusion concentration of vinpocetine injection for 363 patients was more than 0. 06 mg·ml -1 ,and 3 cases of adverse reactions appeared with the main symptoms of rash and drug fever. Among 28 published literatures,19 articles were with the infusion concentration of vinpocetine injection above 0. 06 mg·ml-1 and 8 articles reported adverse reactions in varying degrees. Conclusion:Clinicians should pay attention to the instructions in the clinical course of medication in order to improve the safe and rational use of drugs.
ABSTRACT
Objective To study the protective effect of pyrrolidine dithiocarbamate (PDTC) on acute irradiated mice.Methods The 6-8 weeks old male ICR mice were randomly divided into five groups:irradiation alone group (IR),positive control group (amifostine WR-2721 250 mg/kg) and PDTC of 30,60 and 90 mg/kg dose groups.Each group had 10 mice and the drug was given at 0.5 h before whole body irradiation.At 30 d post-irradiation of 7.5 Gy 137 Cs γrays,the mice survival were observed.At 8 d post-irradiation of 5.0 Gy 137 Cs γ-rays,the peripheral blood,hematopoietic system and organ indexes were observed to evaluate the radiation protective effect of PDTC.Results PDTC increased the 30-day survival rates and 60 mg/kg dose had the most obvious effect by increase the survival to 60％ (6/10).The survivals of irradiation alone group and the amifostine positive control group was 10％ (1/10) and 70％ (7/10),respectively.Compared with the irradiation alone group,60 mg/kg PDTC group had the significant difference in spleen index,WBC,HGB,PLT,bone marrow nucleated cells and colony forming unit of spleen (t =2.354,4.793,2.342,6.542,2.649,3.982,P ＜ 0.05).Conclusions PDTC is effective in radiation protection with an optimum dose of 60 mg/kg.
