ABSTRACT
Objective To investigate the relationship between the disorder of learning and memory in lead rats and the argnine vasopressin (AVP) and the somatotatin (SS) of hippocampus.Methods Sixty healthy 2-month old Sprague-Dawley rats were randomly divided into normal control group and lead group. Normal control group was given deionized water and the lead group was given 0.1% lead acetate deionized water for 3 months to make chronic lead rat. Learning and memory ability was tested by the Y-maze test. The content of AVP and SS in hippocampus were tested by the immunohistochemical method. Results The learning memory ability and the content of AVP and SS in hippocampus CA1 section of the lead group were degraded obviously than the control group(all P0.05)in hippocampus CA3 section of the lead group were degraded also.Conclusion The disorder of the learning and memory of the lead exposure rats may be due to the decrease of the content of AVP and SS in hippocampus.
