ABSTRACT
OBJECTIVE:To provide reference for further implementation and perfection of National Essential Medicine Sys-tem. METHODS:Stratified random sampling method was used to select 252 doctors from Sichuan Luzhou. Questionnaire survey was performed among them about recognition and behavior of them to National Essential Medicine System. Related investigation da-ta was analyzed statistically. RESULTS:A total of 252 questionnaires were issued and 243 valid questionnaires were collected with effective recovery rate of 96.4%. Of 242 respondents who had heard of National Essential Medicine System,the respondents who had heard but not clear occupied the highest percentage (52.1%). Of 149 participants who had participated in national essential medicine knowledge training or study,the proportion ofonly one knowledge training or studywas the highest(57.0%). The sur-vey respondents had a maximum of 45.0% and a minimum of 16.5% of common sense about National Essential Medicine System. After the implementation of National Essential Medicine System,respondents often propagandized National Essential Medicine Sys-tem to diagnosis and treatment objects accounted for only 23.1%. The proportion ofno changechosen for items of work motiva-tion,work efficiency and workload was the highest (all occupied 58.3%);the proportion oflittle influencechosen for item of clinical medication habit was the highest(38.8%). 86.4% of respondents were willing to give priority to the use of national essen-tial medicines;the top 4 reasons wereto obtain training and guidance on the use of essential medicinesto set utilization rate of essential medicines in primary health care institutionsto strengthen the propaganda of National Essential Medicine Systemto evaluate physician's prescriptions regularly. 13.6% were not willing to give priority to the use of national essential medicines;the top 4 reasons werelack of the confidence of the use of national essential medicinespoor accessibility of essential medicinesfear of medical accidents due to prescription essential medicines,lead to medical disputesdon't know what is essential medi-cine. CONCLUSIONS:The primary physicians'perceptions of National Essential Medicine System and the implementation of the System in Luzhou need to be strengthened. The main reason is that few national essential medicine knowledge training or study and poor effects. That the government's supporting poli-cy is not perfect may be one of reasons.
ABSTRACT
Objective:To study the pharmacokinetic process ofbrucine from normal and ultra-micro powder ofsemen strychni in rat serum.Methods:HPLC techniques were used.All pharmacokinetics parameters were calculated with a 3P87 program.Results:The pharmacokinetics results indicated that the normal powder and the ultra-micro powder ofsemen strychni belonged to two compartment open model.The absorb ofbrucine was just several ten minutes, and there was no obvious difference ofTmax between normal powder and ultra-micro powder.This showed that:Brucine was some material that was easily absorbed.But we can find that Cmax increased from(51.13?0.48)?g/L to(69.26?1.40)?g/L after ultra-micro powder preparation which was quite obvious.K,Ka,B and ? had a obvious increase(P
ABSTRACT
Objective:Dissolution test was applied to study the dissolution rates of strychnine from the normal and ultramicro powder of semen strychi. Methods:HPLC techniques was used to detect the dissolution amount and the dissolution velocity of strychnine from the normal and ultra-micro powder of semen strychi. Results:The dissolution velocity of strychnine from the ultra-micro powder was higher than that from the normal powder,but there was no difference in the dissolution amount 4 hours later. Conclusion:The dissolution velocity of strychnine from the ultra-micro powder increased greatly and there was no loss of the principal active.
