强迫游泳实验广泛应用于抗抑郁药物筛选及抑郁机制研究:Ugo Basile新推出的强迫游泳测试仪能够记录温度、动物游泳及攀爬行为。20世纪70年代Porsolt等人研究并设计了强迫游泳实验,将动物(大、小鼠)放进一个有限的空间使之游泳,开始时动物会拼命游泳力图逃脱,一段时间后就变成漂浮不动状态,仅露出鼻孔保持呼吸,四肢偶尔划动以保持身体不至于沉下去,实际是动物放弃逃脱的希望,属于行为绝望。抗抑郁类药物,如选择性再摄取抑制剂能够有效增加动物游泳及攀爬行为,缩短动物不动时间,不动时间越短,抗抑郁作用越强,以此作为抗抑郁药物筛选的指标。
装置包含一个尺寸为20(w)x8(d)x18(h)cm的透明水箱,水轮在箱体中间,直径3.5cm,宽8cm。6个0.5cm的旋浆均匀分布在水轮表面。
装置含有一个温度传感器,可放置在水箱的任意一侧,准确反馈水箱内的实时温度;水轮转动(CW和CCW)能够被仪器的旋转编码器记录下来;单个强迫游泳测试仪可通过USB接口与电脑连接,多个测试仪可通过USB扩展器与同一台电脑相连。

方法介绍:
“A depressed state can be induced in mice by forcing them to swim in a narrow cylinder from which they cannot escape. After a brief period of vigorous activity the mice adopt a characteristic immobile posture which is readily identifiable” (Porsolt et al.).
In other words, mice forced to swim in a restricted space rapidly cease moving and become lethargic. Porsolt et al. named this phenomenon ‘behavioral despair’, and demonstrated that antidepressants selectively reduced the immobility.
The modification suggested by S. Nomura et alia in their paper of 1982 involves a small water wheel set in a water tank, to provide an objective measurement (number of rotations) and overcome the bias intrinsic to Porsolt’s method.
In the habituation phase, the wheel is fixed, so the rodent can climb on it thus identifying it as an escape way. During the test proper, the wheel rotates freely: mice turn the wheel vigorously and when they give up attempts to escape from the water, the wheel stops revolving and the number of rotations are recorded.
“... this water wheel test is more appropriate as screening test for antidepressants than Porsolt’s test with regard to both objectivity and specificity.” (Nomura et al.)
