开发了一种切取小龙虾鼻窦腺的技术。通过摘除和植入的方法。已经证明，小龙虾眼柄的窦腺是动物正常生存所必需的。切除两个腺体的动物比正常动物存活的时间要短得多，而且平均寿命更短。这些切除腺体的动物的术后寿命可以通过植入同种和异种的鼻窦腺组织来延长。更多的证据有力地表明，鼻窦腺通常会分泌一种具有蜕皮抑制作用的物质。这种蜕皮控制的证据来自于相同类型的羽毛。这表明了鼻窦腺对存活率的影响。
A technique for dissecting out the sinus gland of crayfishes was developed. By means of extirpation and implantation expts. it was demonstrated that the sinus gland of the eye-stalk of the crayfish was essential for normal viability of the animal. Animals with both glands removed lived a significantly shorter time than normal animals, and furthermore the avg. post-operational life of these animals with glands removed could be lengthened by both homo- and heteroplastic implants of sinus gland tissue. Additional evidence strongly suggested that the sinus gland normally secreted a substance having a molt-inhibiting action. This evidence for molt control was derived from the same types of expts. that showed the effect of the sinus gland upon viability.
