Expression of Neuroglobin Gene in Hypoxic-ischemic Brain Injury of Newborn Rat / 中华围产医学杂志

ABSTRACT

Objective To investigate the expression and change of neuroglobin (NGB) gene on hypoxic-ischemic brain injury. Methods Fourty-eight wistar rats of 7days old were divided into 6 groups randomly. Five study groups, study (1 min), study (5 min), study (15 min), study (30 min), study (60 min), and control group. The brain tissues were taken at 1 min, 5 min, 15 min, 30 min and 60 min after brain hypoxic-ischemia injury, and nucleic and immunohistochemistry method were used. One-way method of Stata soft-bage was used for statistics. Results There were time-depended pattern of the expression of NGB gene. It increased rapidly at 1 min after ischemia (A1.236), there was significant difference from control group (A0.641; P
