甲壳类在发育过程中,与昆虫类一样需经多次蜕皮,不同点是甲壳类变为成体后还会继续蜕皮。由于甲壳类多营水生生活,饲养和手术都有较多困难,所以到目前为止对其蜕皮机制的认识还不够明确。近十几年来,对甲壳类蜕皮激素的研究,已有不少报道,某些蜕皮激素的化学性质与结构已被确定,而且它们在体内的合成位置、传递方式以及某些生理功能也已被探查。本文就此项研究的近况综述如下。 1.蜕皮激素的种类 甲壳类大约有40,000种,而关于它们的蛇皮激素,只在软甲壳类(Molacostraca)做过较多的研究。在鳃
Crustaceans in the development process, like insects need to be repeated molting, the difference is that crustaceans into adults will continue to molting. Because crustacean multi-bathed aquatic life, feeding and surgery are more difficult, so far the understanding of its molting mechanism is not clear enough. In recent decades, there have been many reports on the research of crustacean ecdysone. The chemical properties and structures of some ecdysone have been identified, and their location in the body, the mode of delivery and some physiological functions have also been reported Exploring. The current status of this research is summarized as follows. 1. Types of ecdysone There are about 40,000 crustaceans, and the snakeskin hormone about them is only studied more in Molacostraca. In the gills
