摘  要:目的:验证Stock等切除睾丸和嗅球建立的大鼠模型是否可成为模拟老年男性抑郁症的一种实验动物模型。方法按随机数字表法,将健康成年雄性SD大鼠随机分为正常组、假手术组、模型组、载体组、氟西汀丙酸睾酮( Flu+TP )组与阿米替林丙酸睾酮( Ami+TP )组,各组均为10只;建立切除睾丸和嗅球的大鼠模型,联合氟西汀或阿米替林与雄激素进行干预,测试各组大鼠的行为变化。结果旷场试验:水平格子数,模型组[(124.50±14.25)格]或载体组[(118.70±10.27)格]均比正常组[(38.20±6.30)格]、假手术组[(33.70±9.58)格]、Flu+TP组[(34.00±9.82)格]与Ami+TP组[(35.20±12.54)格]明显增多,差异有统计学意义(P<0.01);垂直站立数,模型组或载体组均比正常组、假手术组、Flu+TP组和Ami+TP组显著增加,差异有统计学意义(P<0.01)。强迫游泳试验的不动时间:模型组[(131.70±32.44)s]或载体组[(135.10±34.01)s]均比正常组[(66.60±12.06)s]、假手术组[(62.00±13.38)s]、Flu+TP组[(59.60±8.89) s]和Ami+TP组[(64.80±10.78)s]明显延长,差异有统计学意义(P<0.01)。水迷宫试验:逃避潜伏期,模型组[(62.00±26.05)s]或载体组[(60.52±27.00)s]均比正常组[(24.19±9.12)s]、假手术组[(21.06±8.13)s]、Flu+TP组[(22.88±8.01)s]和Ami+TP组[(27.04±10.11)s]明显延长,差异有统计学意义(P<0.01);在原平台象限时间,模型组或载体组均比正常组、假手术组、Flu+TP组和Ami+TP组明显缩短,差异有统计学意义(P<0.01, P<0.05)。结论本研究印证了该模型具有可重复性和可靠性,其可能适合作为一种老年男性抑郁症的实验动物模型供后续研究应用。Objective To evaluate the effectiveness of a major depression animal model for old man es-tablished with orchidectomized(ORX) and subsequently olfactory bulbectomized(OBX) rat. Methods Healthy Sprague-Dawley male adult rats were randomly assigned to six groups with ten rats in each group:intact,sham-oper-ated,model,vehicle,fluoxetine plus testosterone propionate(Flu+TP) and amitriptyline plus testosterone propionate (Ami+TP) groups. ORX+OBX rat model was established. Therapy of Flu or Ami (10 mg/kg,i.p.) combined with TP(25 mg/kg,s.c.) was administered. Behavioral changes of rats in each group were detected. Results Open field test: The number of rat crossing lattices in model((124.50±14.25)lattices) or vehicle group( 118.70± 10.27) was significantly larger than those of intact(38.20±6.30),sham-operated(33.70±9.58),Flu+TP (34.00± 9.82) and Ami+TP group (35.20±12.54). The rearing number of model or vehicle group was also significantly larger than those of intact,sham-operated,Flu+TP and Ami+TP group.Statistical differences in the above corre-sponding comparisons of open field test existed (P〈0.01). Forced swimming test: The immobility time of model ((131.70±32.44)s) or vehicle group ((135.10±34.01)s) was significantly longer than those of intact((66.60± 12.06)s),sham-operated((62.00±13.38)s),Flu+TP((59.60±8.89)s) and Ami+TP group ((64.80±10.78)s). There were statistical differences in the above corresponding comparisons (P〈0.01). Morris water maze test: The escape latency of model((62.00±26.05)s) or vehicle group ((60.52±27.00)s) was significantly longer than those of intact((24.19±9.12)s),sham-operated((21.06±8.13)s),Flu+TP((22.88±8.01)s) and Ami+TP group ((27.04±10.11)s);while the time rat swimming in the quadrant originally put a platform of model or vehicle group was significantly shorter than those of int
