3 . the effect of t active immunization was reversible , and the function of gonad could recover . at the age of 15w , the immuological effects disappeared gradually , and no distinct differences could be observed between immunized and untreated group . 4 本试验结果表明， t - 3 - bsa免疫雏公鸡在一定时间内具有免疫抑制功能，可以代替传统的手术去势法，但抑制作用随着日龄的增长具有可逆性，同时表现出较强的促生长作用。
There was no significant difference of the percent of cgrp positive nerve fibers area between group a . b . c and group d in 4 weeks model ( p = 0 . 276 . 0 . 068 , 0 . 176 ) 2 . in 10 weeks model , the percent of cgrp positive nerve fibers area of control group was significant higher than that of group a , group b , group c ( e = 0 . 000 , . 0 . 000 , 0 . 000 ) 3 4周模型去势组、抑制dht组、补充雄激素组和对照组cgrp阳性神经纤维面积比例差异无统计学意义， 10周模刑对照组阳性神经纤维面积比例明显高于去势组、抑制dht组和补九雄激素组。
In each experimental group , the percent of cgrp positive nerve fibers area in each 4 weeks model was significant higher than that of 10 weeks model ( p = 0 . 013 , 0 . 031 , 0 . 000 ) ; while in control group , there was no significant difference of the percent of cgrp positive nerve fibers area between 4 and 10 weeks models ( p = 0 . 579 ) 去势组、抑制dht组和补充雄激素组cgrp阳性神经纤维面积比例两两比较4周模型大于10周模型；对照组4周模型和10周模型阳性神经纤维面积比例无差异。 2浙i人7外科” ： （泌冰外）儿敏光m大义结论： 1
