Effect of Movement Restrict on the Expression of 5-HT Receptor Subtypes in Rat Brain / 中国临床心理学杂志

ABSTRACT

Objective:To explore the 5-HT mechanism of stress . Methods:The method of polymerase chain reaction (PCR) was used to detect the presence of 5-HT receptor subtypes in the hippocampus,hypothalamic and midbrain of the rat after 30days of movement restrict compared with normal cage control groups (CC) . The specific oligonucleotide primers were synthesized based on the complementary DNA sequence for each of the rat 5-HT 1A and 5-HT 2A receptor subtypes . Results: The expression of 5-HT 1A receptor subtypes in each regions of the rat brain after movement restrict were signifcantly lower than that of the CC groups, and the expression of 5-HT 2A receptor subtype were signifcantly higher( P
