四眼斑水龟雌性生殖器官组织结构的季节变化

应用石蜡常规切片，HE染色，分别在3月（春季）、8月（夏季）、10月（秋季）、1月（冬季），对24只四眼斑水龟雌性生殖器官组织结构变化进行研究，结果表明：四眼斑水龟雌性生殖器官的形态和结构存在季节性的变化，8月卵泡开始发育，卵巢增重，子宫腺增多；10月卵巢增重达最大，卵泡发育成熟开始排卵，随后形成黄体，进入排卵期。翌年的1～3月卵巢重量减轻，输卵管管腔增大，腺体增多，子宫肌层不断增厚，进入产卵期。

Seasonal Changes of Female Reproductive Organs of Sacalia quadriocllata

In this paper,the histological structure of 24 Sacalia quadriocllata female reproductive organs was observed on paraffin sections stained with HE in March(spring),August(summer),October(autumn)and January(winter).The results showed:seasonal changes happened in female reproductive system form and structure.In August,follicle began to develop and the weight of ovary and uterine gland increased.In October,the weight of ovary reached maximum,follicle was mature and began to ovulate,then yellow body of ovary formed,entering the ovulatory period.The next year,the weight of ovary eased from January to March,oviduct became larger,body of gland increased,muscular layer increased gradually,enter oviposition period.
