ABSTRACT
We aroused students' learning interest,adjusted teaching contents,played the appropriate role of teachers,optimized teaching means and carried out comprehensive evaluation based on special characteristics of the optional course environmental eugenics and the knowledge structure of students to improve the teaching quality and teaching effect as well as make this course contribute to comprehensive ability of medical students.
ABSTRACT
Objective To observe the effect of glutamine on gut barrier function and antioxidative capacity in rats with radiation damage. Methods A total of 30 healthy Wistar male rats were randomly divided into three groups: control group, GLN enriched group(+GLN) and GLN free group( GLN). Rats in control and GLN group were fed with a basic diet, while 3% GLN was added into the diet of the +GLN group. On the 15th day, rats in GLN and +GLN groups received 9.0 Gy 60 Co ? irradiation in total body. The rate of the gut bacterial translocation and the level of endotoxin, GSH and SOD in the serum were determined at the end of the experiment. Results The rate of bacterial translocation and serum endoxin level were significantly lower in +GLN than in GLN, and GSH and SOD levels in serum were significantly higher in +GLN than in GLN. Conclusion Glutamine supplement is helpful to protect the gut barrier function and improve the antioxidation capacity in rats with radiation injury.
