联合使用电刺激采精与直肠按摩对大熊猫精液采集的影响 总被引：1，自引：0，他引：1
研究了实施经直肠按摩输精管壶腹部对大熊猫精液采集的影响。B超检查结果显示,大熊猫具有发达的输精管壶腹部,其位于膀胱与直肠之间;单独实施经直肠按摩输精管壶腹部200~400次后,所有个体均出现程度不等的阴茎勃起,平均阴茎周长从按摩前的6.33 cm增加到7.49 cm,但是单独使用直肠按摩还不足以刺激大熊猫的射精反应。为确定联合使用直肠按摩与电刺激采精对大熊猫精液采集的影响,开展了进一步实验;电刺激按常规方式进行,在每个刺激系列结束后接着进行直肠按摩100~200次。结果显示,对于电刺激采精量低于1.68 mL的个体,直肠按摩可显著增加采精量(P<0.05),采精量从(0.36±0.66)mL增加到(0.95±0.99)mL,但是对于电刺激后采精量在1.9 mL以上的个体,直肠按摩不能增加采精量。电刺激后进行直肠按摩可将大熊猫采精成功率从44%提高到88%。 相似文献

An 11-year-old, female, spayed caracal (Caracal caracal) presented with a 3-month history of intermittent anorexia, vomiting, and weight loss. At examination, bilateral anterior uveitis with anisocoria was present. Further examination under general anesthesia revealed the anterior chamber of the right eye contained copious amounts of thick fibrin, hypopyon, and hyphema obscuring the ventral pupil margin and ventral iris. Aqueous paracentesis revealed a cytologic diagnosis of large granular lymphoma. Additional antemortem diagnostics (computed tomography, ultrasound with fine needle aspiration, and cytology) confirmed the diagnosis of multicentric large granular lymphoma with associated intestinal perforation. Necropsy and histopathology confirmed multicentric large granular lymphoma in the right eye, jejunum, mesenteric lymph nodes, and right kidney. Large granular lymphoma in nondomestic felids is likely rare since it has not been previously reported, but should be considered as a differential in any felid species with anterior uveitis or when lymphoma is considered. In the case of this caracal, the use of aqueous paracentesis with cytology was a powerful diagnostic. 相似文献
