Cervical and endometrial swabs were taken from 7 mares at various stages of the oestrous cycle. There was no consistent pattern of cell change throughout the cycle. The dominant cell in smears from normal mares was the columnar epithelial cell, especially in smears obtained during oestrus. A ciliated columnar epithelial cell was found much less frequently but appeared more often in smears before oestrus. Endometrial biopsies were also collected from 7 mares at intervals 2-3 weeks over an 8-month period from the beginning of spring to the end of autumn. There was no obvious change in the endometrial histology during this time. No evidence of acute or chronic inflammatory change was found in sequential biopsies. The inflammatory response to a single endometrial biopsy and subsequent endometrial biopsies, as measured by exfoliative cytology 48 h after biopsy, was minimal. Bacteria were recovered after aerobic culture of cervical swabs on more occasions 48 h after than before uterine biopsy, but they were considered not to be significant.
从7匹处于发情周期不同阶段的母马采集了宫颈和子宫内膜拭子。在整个周期中，细胞变化没有一致的模式。正常母马涂片的主要细胞是柱状上皮细胞，尤其是在发情期获得的涂片中。纤毛柱状上皮细胞较少见，但在发情前的涂片中更常出现。在从春季开始到秋季结束的8个月期间，每隔2 - 3周还从7匹母马采集子宫内膜活检样本。在此期间，子宫内膜组织学没有明显变化。在连续活检中未发现急性或慢性炎症变化的证据。通过活检后48小时的脱落细胞学检测，对单次子宫内膜活检及随后的子宫内膜活检的炎症反应最小。子宫活检后48小时，宫颈拭子需氧培养比活检前更常检出细菌，但认为这些细菌不具有显著性。
