Active immunization should be started concurrently with therapy 在施行療程的同時亦須接種疫苗以產生自動免疫。
Artificial active immunization 人工主動免疫
Active immunization with pertussis vaccine is an effective way to prevent the disease 7 .接種百日咳疫苗可以有效預防百日咳。
Influenza may be prevented by active immunization with a polyvalent killed or subunit vaccine 可以通過主動免疫接種多價滅活疫苗或亞單位疫苗預防流感。
8 . active immunization with diphtheria toxoid can provide long - lasting protection in the majority of immunized children 8 .大部分曾接種白喉疫苗的兒童都能保持長期免疫能力。
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 本試驗結果表明, t - 3 - bsa免疫雛公雞在一定時間內具有免疫抑制功能,可以代替傳統的手術去勢法,但抑制作用隨著日齡的增長具有可逆性,同時表現出較強的促生長作用。
The objective of this study is to evaluate the effects of active immunization against ss on nutrient digestion and metabolism , growth and carcass composition of the growing hu - sheep ; 2 , on the ss secretion in fundus , antrum and pancreas and the ablity of the antibodies to integrate free ss ; 3 , on passage rates of digesta ; 4 , on activities of digestive enzymes in pancreas and digesta ; 4 , on gene expression of gh in pituitary 本項研究內容集中于后者,主要的試驗目的是: 1生長抑素主動免疫對ss進行免疫中和對生長期湖羊生長,營養物的消化,代謝,胴體組成影響; 2對胃竇膜,基底膜和胰腺ss分泌以及ss抗體結合ss的能力影響; 3
T active immunization could maintain its castration for a period , at the age of 11w , the development of combs and wattles were evidently slower in the immunized groups ( p < 0 . 05 ) , and the testes atrophied . meanwhile , both its serum t concentration and body weight were evidently lower than the untreated group . 2 . the does of 0 . 2mg / ml produced the best immunisation performance and promotion growth effecct , we could induce the dosage was the main factor in deciding the final effect , injection at w3 achieved the best result 11周齡時,各免疫組雞體重、血漿睪酮含量顯著( p 0 . 05 )低于對照組,睪丸及冠垂發育受到抑制,明顯發生萎縮,其中以0 . 2mg / ml劑量, 3周齡免疫抑制作用最為明顯;此后隨著日齡的增長,免疫抑制作用逐漸下降,到15周齡時,免疫抑制作用明顯逆轉,機體的生長發育恢復正常,免疫各組與對照組相比測定指標無顯著性差異( p 0 . 05 ) ;至19周齡,各免疫組睪丸和冠垂生長發育、體重、血漿睪酮含量都顯著( p 0 . 05 )高于對照組,其中以0 . 2mg / ml劑量組, 9周齡免疫促生長作用最為明顯。
百科解釋
Active immunization is the induction of immunity after exposure to an antigen. Antibodies are created by the recipient and may be stored permanently.
