摘　　要：本试验对存在于广东云浮市境内的棕果蝠雌性生殖器官进行了大体及组织学观察。棕果蝠雌性生殖系统由卵巢、输卵管、子宫、阴道、阴道前庭和阴门组成。卵巢一对,位于两侧肾的后方,包于输卵管系膜内,肉眼不易区分。输卵管很短,分为漏斗部、壶腹部和峡部,黏膜上皮为单层柱状上皮,黏膜形成纵向黏膜褶,并具有宽阔的输卵管腺。子宫为双子宫类型,根据子宫内膜上皮类型,每侧子宫分为子宫角和子宫颈,子宫角内膜具有高柱状上皮,并形成类似于输卵管腺的子宫腺。子宫角较粗,外径在1000μm以上,比输卵管外径大1倍。子宫颈内膜上皮为单层高柱状分泌型细胞。子宫颈内膜形成发达的纵行黏膜皱褶,但不形成宫颈腺或腺样隐窝;两个子宫颈后半部共同形成一个圆锥状子宫颈阴道部,相当发达,顶端向后,其外表面也具有一层高柱状分泌型上皮细胞。两个子宫颈管未能抵达子宫颈后端,而是分别开口于子宫颈阴道部中间段(前后向上)的腹侧面上,分别开口于阴道。阴道穹窿长而深,其最前部形成一对盲管,分别位于左右两宫颈管的外侧。阴道长而宽阔。其前端形成阴道穹窿。阴道黏膜为厚而角化的复层扁平上皮。阴道后腹侧有雌性尿道的开口。阴门呈椭圆孔状,未形成左右两个阴唇。This study performed gross and histological observations on the female reproductive organs in the Rousettus leschenauti that were captured in the caves in Yunfu county,Guangdong province of China.The reproductive organs included ovaries,oviducts,uteri,vagina,vaginal vestibule and vaginal orifice.A pair of ovaries situated behind the kidneys and were embedded in the mesosalprinx and could not be identified easily with naked eyes.The rather short oviducts were lined with a layer of columnar epithelium and could be divided into the infundibula,ampulla and isthmus,according to the structures and positions.The oviduct mucous membrane formed longitudinal folds and broad glands of oviduct.The uterus was absolutely duplex and each of them was comprised of uterine horn and uterine cervix,according the morphologies of the lining epithelium.In the uterine horn,the endometrium was lined with the simple high columnar epithelium and the epithelium cells presented identical morphological characteristics compared with that of oviduct.The horns were thicker than oviducts and the external diameter of the uterine horn was over 1000μm,being two times as thick as oviduct.Whereas the endometrium of the cervix was lined with mucus-secreting simple high columnar epithelium.Furthermore,the cervix could be divided into supervaginal part and vaginal part,according to whether to be accompanied by the vaginal fornix.The endometrium of the cervix formed developed longitudinal folds,but did not form cervical glands.The mucus-secreting simple high columnar epithelium not only lined on the endometrium of the cervix,but also covered on the outside surface of the vaginal part of the cervix.The left and right vaginal parts united each other and formed a conoid with the tip toward to the caudal.The canals of cervix opened respectively to the vagina on the ventral surface of the middle part(rostracaudly)of the vaginal part of cervix.The vagina was a long and wide canal with deep vaginal fornix toward to the cranial.The vaginal fornix was deep and lo
