摘要  [目的]利用卵巢组织石蜡切片自发熒光观察斑节对虾卵母细胞发育。[方法] 研究采用普通石蜡切片技术获得斑节对虾发育各期卵巢组织切片,采用苏木青/伊红染色后利用3种自发荧光对卵巢组织切片进行观察,探讨绿色自发荧光下观察卵母细胞不同发育阶段需要的最适曝光时间。[结果] 卵巢组织切片直接自发荧光观察卵母细胞的发育较HE染色后观察更为方便、有效,且切片可以继续用于后续试验。3种自发荧光中,绿色自发荧光的观察效果最好。[结论]  该研究可为快速观察斑节对虾卵母细胞发育和高效利用试验材料提供了新思路和新方法。

Abstract     [Objective] The ovarian development of Penaeus monodon was observed by using auto-fluorescence of oocyte paraffin section. [Method] The paraffin section of ovary in P. monodon indifferent development stages by using common paraffin section technology. The ovary sections were observed by using three kinds of auto-fluorescences after hematoxylin and eosin dyeing. The optimum exposure time for different development stages of oocytes under green auto-fluorescence was discussed. [Result] It was more convenient and effective to observe the development of oocyte by using auto-fluorescence of ovary sections than that by HE dyeing. And the sections could be used in further experiments. Among three kinds of auto-fluorescence, the observation effects by using green auto-fluorescence was the best. [Conclusion]The research could provide new thought and method for the rapidly observing the development of P. monodon oocytes and effectively utilizing the test materials.

斑节对虾(Penaeus monodon)作为世界三大对虾养殖品种之一[1-3],在国内外都有着大量研究报道。斑节对虾的全人工繁育技术已经成功,但斑节对虾卵巢发育的分子机理仍然不十分清楚。近年来,已有多个斑节对虾卵巢发育相关的基因被研究[4-7],组织切片观察是目前常用的鉴定卵母细胞发育的方法,以卵巢组织切片为基础的免疫组化、原位杂交等技术广泛应用于在研究卵巢发育相关因子在卵母细胞中的定位等研究中。……
