 note = {A study has been made of the effects on uterine movements of the preimplantational stage in rabbits by mean of the abdominal window method. This is well applicable for the observation of various modes of uterine movements under the physiological condition, which is not attainable by any other experimental methods. The results are summarized as follows: 1) The movements of the uterus can be approximately classified into different kinds of types, namely, peristalsis, rotation, pendulum, and segment. Among these types of movements, the peristalsis is predominant. 2) The frequency of the peristalsis increases considerably after copulation, showing its maximum value in 7 hrs. after copulation, but in a day after copulation it decreases to the low value. Again it increases from 2 to 4 days after copulation and decreases subsequently to the day of implantation, 7 days after copulation. 3) The peristalsis of the uterus can be considered as a contraction wave which advances along the uterine corner upwards or downwards. Though being produced in any other portion of uterus, the start of waves is mainly produced in either the cervical-end or the tubal-end. 4) The frequency of downward-waves in the peristalsis is higher than that of the upward-waves for a time in the course of the periods from 2 to 5 days after copulation. 5) It is observed that blastocyst in the uterine lumen transfers by the uterine peristalsis which occurs in 5 or 6 days after copulation. Therefore the reach of blastocysts to the uterus and the distributions of blastocysts in the uterus are considered to be helped by the uterine peristalsis. 6) The contractive rate of the uterine peristalsis increases after copulation, showing its maximum value in 7 hrs. after copulation, but it decreases subsequently to the day of implantation, 7 days after copulation., Article, 信州大学農学部学術報告 9: 83-91(1965)},
