卵黄腺

Results The body of the two species consists of scolex, neck and strobilae. Each mature proglottid showed a set of male and female reproductive system and genital openings on one side.

Egg capsule showed no clear boundary and contained only one egg. However, the scolex and suckers of R. tetragona were oval in shape, and the neck was long and thin. The ovary was flower-like. Each egg capsule contained 4-12 eggs and many calcareous corpuscles, each of which was surrounded by a membrane.

四角瑞利绦虫链体相对较长，头节及吸盘均呈椭圆形，颈部尤为细长；卵巢呈花朵样分瓣，卵黄腺呈豆状，卵囊周围有明显的囊壁，卵囊内含有4～12个数目不等的虫卵及大量成团的细小折光性颗粒。

Testes located on both sides of the ovary and behind vitellarium. A complete worm of R. echinobothrida was shorter than R. tetragona , with a round scolex and suckers and short neck. The ovary looked like leaf and vitellarium was in kidney-shape. There were many acid particles and calcareous corpuscles in gravid proglottids.

不同之处，棘盘瑞利绦虫链体较短，头节及吸盘均呈圆形，其颈部较短、不明显；卵巢呈叶状分支，卵黄腺呈肾形，孕节中散布有大量嗜酸性颗粒及细小折光性物质，卵囊周围无明显界线，其内仅含1个虫卵。

Results The CsATP-synt_B protein appeared to distribute all over the adult worm, especially abundant on the acetabulum, ovary, vitellarium and tegument.

结果 CsATP-synt_B蛋白在华支睾吸虫成虫中分布较为广泛，主要分布在腹吸盘、卵巢、卵黄腺和皮层。

Struma Cuvier consists of three parts: digenetic gland, the reproductive ducts and subsidiary glands of male, the reproductive ducts and subsidiary glands of female.

雄性生殖管道由输精管、阴茎、刺激器组成，附性腺为主要的附属腺体；雌性生殖管道由输卵管、受精囊、阴道组成，附属腺体主要为卵黄腺和蛋白腺。

The reproductive duct of the female consisted of the oviduct, receptaculum seminis, and vagina, and the main subsidiary glands were the viteline gland and albumen gland.

雄性生殖管道由输精管、阴茎、刺激器组成，前列腺为主要的附属腺体；雌性生殖管道由输卵管、受精囊、阴道组成，附属腺体主要为卵黄腺和蛋白腺。

Tissue transcription analysis indicated that chIL-2Rγ mRNA was found in cerebrum,cerebellum,medulla spinalis,bursa of fabricius,thymus,spleen,bone marrow,cecal tonsil,stomachus glandularis,stomachus muscularis,jejunum,yolk sac diverticulum,ileum,cecum,rectum,heart,kidney,lung,liver,skeletal muscle and skin, but was not detected in duodenum and testis.

RT-PCR检测发现，鸡IL-2Rγ mRNA分布于大脑、小脑、脊髓、腔上囊、脾、胸腺、骨髓、盲肠扁桃体、腺胃、肌胃、空肠、卵黄囊憩室、回肠、盲肠、直肠、心脏、肾、肺、肝、骨骼肌和皮肤，而在十二指肠和睾丸中没有检测到其转录。

The ontogeny of hemopoietic and immune organs in the Chinese soft shelled turtl e, Trionyx sinensis , was studied and the morphological characteristics of tw o to three embryos from each embryonic stage described with histological examination .
