中文摘要 | 雌性白鼻心屬非季節性多週期動物,其動情週期以18天型為主。本實驗室先前已完成其生殖週期中外生殖器外觀、內分泌型態與陰道細胞相變化相關報告。但至今,白鼻心子宮角及卵巢型態上之週期變化仍未明朗。本試驗乃採非侵入性之超音波影像技術配合外生殖器與內分泌變化分析,來進行子宮角及卵巢超音波學判讀,以建立其動情週期影像學資料庫。6頭性成熟之雌性白鼻心(>20月齡)於動情週期DO、D4、D7、D10、D14、D18天(DO=陰戶外觀開始紅腫當天)分別以7.5MH(下标 z)直線探頭進行超音波掃描連續兩個完整週期,同時採樣分析血清助孕素與雌二醇。由影像掃描分析發現,子宮角直徑於濾泡期(DO、D4、D7)直徑上明顯較黃體期(D10、D14、D18)為寬(P<0.05)。卵巢縱徑在DO開始增寬,於D7達到最寬;且在黃體期(D10、D14)明顯降低(p<0.05)。卵巢之橫徑在濾泡期各天及黃體末期D18明顯小於黃體期D10及D14(p<0.05)。卵巢之面積以濾泡期D4及D7明顯大於其他各天(p<0.05)。由結果顯示顯示在雌性白鼻心整個動情週期變化中,子宮角於濾泡期受到內泌素影響造成子宮壁之充血腫脹而有明顯變寬,直徑上較黃體期為寬;且濾泡期的濾泡發育影響卵巢之縱軸變寬,而黃體期的黃體的發育則影響卵巢橫軸變化。卵巢總面積,於進入濾泡期逐漸增大,進入黃體期則漸減。整體而言,在白鼻心動情週期中,內泌素之變化影響其瀘泡與黃體之發育,進而影響子宮與卵巢在其直徑與面積上有互有消長現象。相關資料可以做為未來生理學研究與相關生殖醫學之參考。 |
英文摘要 | The female Formosan gem-faced civets (Paguma larvata taivana) is classified to the non-seasonal polyestrous cycles. The ovarian activity has been previously reported by our team, based on sex hormone fluctuations. However, until recently the ultrasounographic appearance of internal genital organs was not been published in this species. Six sexually matured female civets were scanned by ultrasonic liner transducer with 7.5 MHz on DO, D4, D7, D1O, D14 and D18 during two consecutive estrous cycles. Simultaneously, serum estradiol and progesterone were assayed. The ultrasonographic examinations revealed: the diameter of uterus horn in follicle phase (DO, D4, D7) wider than the corpus luteum phase (D10, D14, 18) (p<0.05), the transverse diameter of the ovary on DO, D4, D7 and D18 significantly small than D10 and D14 (p<0.05), the vertical diameter of the ovary increasing from DO to the largest in D7 and remarkably reduced in leuteal phase (D10, D14) (p<0.05) and the calculated ovarian area obviously greater on D4 and D7 than other days (p<0.05). These data indicate that ultrasonographic changes of ovary and uterus are associated with fluctuations of estradiol and progesterone both in lollicular and luteal phases. Relevant information could be beneficial to future physiology study and gynecologic medicine in Formosan gem-laced civets. |
