Abstract:
Objective To establish and evaluate anxiety and depression like behaviors in MPTP-in-duced chronic Parkinsonism cynomolgus monkey. Methods Ten cynomolgus monkeys ( 15. 0 ± 1. 5 years old) were divided into normal group and MPTP-induced parkinsonism group(PD group),5 animals in each group. The behavioral methods for evaluating the anxiety and depression like behaviors in non-human prima-tes included Apathy Feeding Test (AFT),Human Intruder Test (HIT),Novel Fruit Test (NFT) and Preda-tor Confrontation Test (PCT). The changes in behavioral indicators between the two groups were analyzed. Results In AFT,PD group spent more time in observing food on both sides,and significantly higher than that in normal group (left:0. 73(0. 49) s,0. 50(0. 28) s,P<0. 01;right:0. 75(0. 60) s,0. 53(0. 16) s,P<0. 01),moreover PD group had limb disorder on the right side,and spent more time in taking food which sig-nificantly more than normal group (0. 83(0. 20) s,0. 57(0. 14) s,P<0. 01). In HIT,PD group moved and stood better than that in normal group,and occurred abnormal behaviors,such as climbed,grinded,scratched and shook cages (P>0. 05),while normal group spent more time in the back of cage during Stare and Back period( Stare:0(64. 70)s,111. 27(38. 94)s,P=0. 033; Back:0(25. 84) s,120(114. 69) s; H=17. 397). Finally,PD group had lower take-up rate and higher withdrawal rate than normal group in PCT(P>0. 05). Conclusion This study establishes a multi-angle evaluation of behavioral methods for anxiety and depres-sion in non-human primates. The analysis confirmed that chronic Parkinson's disease cynomolgus monkeys has different degrees of anxiety and depression,which provides a new method for preclinical intervention in Parkinson's disease.
