Abstract
Objective: To determine the effect of fibroblast growth factor 2 on cognitive function in neonatal rats with hypoxicischaemic brain injury. Methods: The randomised controlled study was conducted from January to June 2011 at Mersin University, School of Medicine, Experimental Animals Research Laboratory and Physiology Behaviour Laboratory, Mersin, Turkey. It included 7-d-old male rats that were randomised into four groups: fibroblast growth factor 2-20, fibroblast growth factor 2-40, control and sham. All the rats, except those in the sham group, were kept in a hypoxia chamber containing 8% oxygen for 2 hours following ligation of the right carotid artery. After hypoxic-ischaemic brain injury was induced, 20 ng G-1 or 40 ng G-1 of fibroblast growth factor 2 was administered via the intraperitoneal route. The terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labelling method was used to evaluate neuronal apoptosis. The Morris water maze (MWM) test was administered to the rats at age 14 weeks. Results: Of the 78 rats on the study, 18 (23%) were in the sham group, while the other three groups had 20 (25.6%) rats each. The number of apoptotic neurons in the right hemisphere in the experimental groups was significantly lower than in the control group (p=0.004 and p
