RESUMO
The scientific research was integrated with medical statistics experiments in view of the experimental teaching practice of medical statistics.The experimental teaching system and evaluation methods of medical statistics were formed,characterized with research task-oriented,a combination of theory,practice and scientific research to guide the students to study medical statistics systematically,such as project design,collecting data,sorting data and analyzing data.The teaching method boosts the students' enthusiasm,and cultivates students' ability to solve practical problems by using statistical principles.
RESUMO
In order to improve the quality of nursing dissertations,we combined the teaching of nursing research with clinical internship to teach nursing dissertation writing,following the process of program input-situation experience-clinical internship-problem study-dissertation writing.Taking problem study as the leading role,students as subject,self experience as the main access and tutors as whole-process instructors,we taught and evaluated nursing dissertations at different stages.Students'interests in scientific research,enthusiasm for participation and quality of dissertations were improved effectively.95.78％ of the students showed positive attitude to this teaching method.
RESUMO
The anti-mutation effect of flesh of clam Merectix meretrix Linnaeus was studied . The increase in the rate of micronuclei of mice bone -marrow polychromatic erythrocytes induced by Cy (25 mg/kg X 2d, ip) or Ur (0. 5 g/kg X 4d , ip) was inhibited by decoctio of flesh of Meretrix merelrix Linnaeus (20g/kgX7d, ig).
RESUMO
Hydrolysate of Meretrix meretrix soft tissue (HMST ) (20, 10g/kg ,po.for 14d ) could markedly inhibit the increase of serum total cholesterol(TC)and triglyceride(TG),enhance the content of high density lipoprotein cholesterol(HLD-C) ;reduced cholesterol(Ch)of the liver(for 28d)in hyperlipimic quail ;and it could also reduce whole blood viscosity in normal and hyperlipemic quail (for 21d).In addition.it could suppress the platelet aggregation induced by ADP in rabbits in vitro. The results show that HMST obviously decreased blood lipid and whole blood viscosity .inhibited platelet aggregation.
RESUMO
AIM: To observe the difference of actions among three traditional compl ex prescriptions with the same composition but the different dosage, including X iaochengqi Decoction, Houpudahuang Decoction and Houpusanwu Decoction, so as to provide evidence for their different clinical applications. METHODS: A series of experiments were performed, including carbon p rop ellance in small intestine, black stool excretion, cough induced by ammonia liqu or and phenol red secretion from trachea. RESULTS: Three prescriptions all enhanced carbon propellance in sma ll intestine at the high dosage, while at the low dosage only Houpusanwu Decoct ion showed the significant effect. They all shortened the latency of black stool a nd increased their total amounts in 6 hours at the high dosage, while at the low dosage Xiaochengqi Decoction and Houpudahuang Decoction had the significant p urgative action. Houpudahuang Decoction remarkably prolonged cough latency, dec reased cough times and enhanced phenol red secretion from trachea, while other t wo prescriptions had no obvious effects. CONCLUSION: Such results showed that Xiaochengqi Decoction had the better purgative action, while Houpusanwu Decoction regulated Qi strongerly, a nd Houpudanghuang Decoction showed the marked actions of relieving cough and re solving phlegm.
RESUMO
Acute ligation of the common carotid artery on one side internal carotid artery on opposite side resulted in experimental cerebral ischemia in rabbit. Measurement of thromboxane B_2 (TXB_2) and 6-Keto-prostaglandin F_(1?)(6-Keto-PGF_(1?))in rabbit plasma were done by radioimmunoassay. Blood samples were collected from the peripheral vein and internal carotid vein. The results were as follows:1. The concentration of TXB_2 in rabbit cerebral ischemia (ligation after 30 min.) was significantly (P
