梅花鹿(Cervus nippon hortulorum)茸角生长发育各阶段血浆睾酮、雌二醇的含量变化

本文用放射免疫测定法对3个不同年龄组的雄性东北梅花鹿茸角生长发育各阶段外周血中的睾酮、雌二醇含量进行了测定。茸期两种激素差异很大,睾酮含量低,雌二醇高,骨化期二者增高很快。对这两种激素含量的变化与茸角发育各阶段的关系进行了讨论。认为只有在二种激素同时增加时,鹿角才能骨化。

VARIATION OF TESTOSTERONE AND ESTRADIOL LEVELS IN PLASMA DURING EVERY STAGE OF GROWTH OF SIKA DEER ANTLER

The authors tested the contents of testosterone and estradiol in plasma of sika deer during every stage of growth of deer antler by radioimmunoassay in 1984. The role of sex hormones in the growth of deer antlers was discussed.17 male sika deer from deer farm of the Institute of Special Products,Chinese Academy of Agricultural Science, were divided into 3 age groups.The first group had 6 individuals (8 years old), the second 5 individuals (4 years old), the third 6 individuals (3 years old) .In velvet, the contents of testosterone differed greatly from that of estradiol, the testosterone level was low and the estradiol high during the fast growth period of pilose antler.In olssification and antler bony period,the contents of testosterone and estradiol increased fast.The authors considered that there was a cooperation of testosterone and estradiol in the growth of deer antler,the pilose antler could become bony antler thoroughly only when the two sex hormones increased at the same time.
