| 摘 要： | 关于文昌鱼生殖活动的调节,Tjoa和Welsch根据电镜的观察,推测文昌鱼头部轮器上的哈氏窝(Hatschek’s pit)可能与脊椎动物的脑下垂体同源。最近,张致一等用荧光免疫法研究发现轮器上的哈氏窝上皮细胞有与LH抗血清产生沉淀反应的分泌颗粒,从而进一步证实了Tjoa等人的看法。我们在光学显微镜下也观察到哈氏窝上皮细胞内分泌颗粒的数量,在性腺发育的不同阶段有明显的区别(待发表的资料),提示哈氏窝上皮细胞与性腺发

| Abstract: | The homogenate of the wheelorgan and Hatachek's pit of Amphioxusis subcutaneously injected into theyoung toad at a dose of 0.5 ml (con-taining 5 or 10 wheel organ and Hat-schick's pit of Amphioxus) for 3 or 7days.It causes a marked increaseof testicular weight of the young toadand promotes spermatogenesis acti-vity. The results obtained in this ex-periment indicate that:(1) the homogenate of the wheel organ andHatschek's pit of Amphioxus may contain gonadotrophin-like substance (s);(2) this substance seems to have nospecies specificity. |
