ABSTRACT
Biochemistry and molecular biology is one of the most important professional basic courses for students in medical universities.Constructing scientific teaching quality control system for biochemistry and molecular biology is essential for improving its teaching quality.This paper discussed on some principles needed to be followed in constructing the teaching quality control system for biochemistry and molecular biology in medical universities and elucidated the three leveled frame of this system including university,college and department.This paper also illuminated on the main contents,implementation,organization system,evaluation system and incentive measures of this teaching quality control system.
ABSTRACT
Objective To study the dynamic changes of the activities of superoxide dismutase (SOD), amylase (AM) and alkaline phosphatase (ALP) and of the contents of epithelium growth factors (EGF) and insulin growth factors (IGF-1) in human colostrum (lactation 1-7 days postpartum). Methods A total of 118 samples of human colostrum were taken from 20 healthy women postpartum. The activities of SOD, AM and ALP in human colostrum were determined by methods of pyrogallol autoxidation, colorimetry of iodine-starch and pyrocatechol phosphate respectively. EGF and IGF-1 contents in human colostrum were measured by radioimmunoassay. Results The SOD activity of human colostrum increased slightly during lactation 1-4 days postpartum, from (18.7?2.2) kU/L to (22.5?2.9) kU/L, then it tended to decrease, being (11.2?2.1) kU/L on the 7th day. The SOD activities in lactation 1-5 days postpartum were significantly higher than that on day 7 ( P
