Ammonia is toxic to fish in natural and artificial waters.We evaluated the acute(96 h) and chronic(21 d) toxicity of un-ionized ammonia to GH transgenic common carp(Cyprinus carpio L.) and non-transgenic common carp u...
This work was supported by the State "863" High-Tech Project (Grant Nos. 101-05-01 and 101-06-02).
Recornbinant "all-fish" growth hormone gene (GH) was microinjected into the fertilized eggs of carp. A comparison between the growth traits of transgenics and non-transgenics was carried out, and the transgenic indivi...
Antral follicles are present in the ovaries throughout gestation. These follicles are 'physically immature' and cannot ovulate under the induction of LH/hCG. The purpose of the present study is to examine whether foll...
Diapause hormone (DH) is a neurohormone which is secreted from suboesophageal ganglion and responsible for induction of embryonic diapause in many insects. Using rapid amplification of the cDNA ends (RACE) method, the...
This review summarizes the recent discoveries of many authors who found that in amphioxus Hatschek’s pit is capable of synthesizing vertebrate gonadotropin_like substance, and that the content of gonadotropin_releasi...
EPIDIDYMIS is the site where spermatozoa released from testis undergo maturation and become capable of fertilizing ova.The epididymal secretions including enzymes,nutrients and hor-mones are believed to be essential f...
IT has been demonstrated that two reproductive hormones,gonadotropin-releasing hormone(GnRH)and gonadotropin(GTH),exist in the nervous system and Hatschek’s pit oflancelet,a species of Cephalochordata,and that these ...
The juvenile hormones (JH) are critical to the contro1 of insect development andreproduction. The production of JH by the corpora allata (CA) is regulatd in part bypeptides originating from brain. One group of these p...

Zhang Zhi-yi et al.demonstrated that sex steroid hormone exists in the maturegonads(ovaries and testes)of amphioxus.So far,it is not clear whether the content ofsex steroid hormone changes correlatively with the diffe...
