title: [Chronobiological distinctions in swimming behaviour of intact and ovariectomised rats females].
abstract: The forced swimming (experimental model of depression) of intact and ovarioectomized rats-females using chronobiological approach was investigated. "The index of depression" of intact rats-females in a stage of proestrus/estrus was a little higher than in diestrus 1/2 in the morning and evening was established. Thus "the index of depression" in evening time was great. "The index of depression" of female in condition of diestrus 1/2 in the evening was lower in comparison with morning hours, and in a phase proestrus/estrus it was higher in the evening. "The index of depression" of ovarioectomized females in comparison with intact rats, both in the morning and in the evening, was higher. Thus the parameter of ovario-ectomized females in the evening was lesser than in the morning. However, in comparison with intact females the change of "the index of depression" in ovario-ectomized females in the evening was lesser than in the morning.
