但是,在染色體的數目上有顯著的差異。另外,染色體間的長短差別也非常明顯。由家蠶生殖腺得到的減數分裂中期染色體和胚胎得到有絲分裂的中期染色體,其染色體長短差異不明顯,而binn細胞的中期染色體長短非常不一致,差異非常顯著。During organogenesis such as formation of nervous system, angiogenesis, etc the cell mechanisms involved are similar to those of carcinogens, such as cell proliferation, differentiation, migration, etc. and there is no shortage of embryos
利用斑馬魚生物特性體外受精胚胎透明發育期短,可做為經濟且快速的藥物組織特異性篩選系統。Spf chickens with 21 - day - old were infected subcutaneously with oil - emulsion vaccine of ibdv of germinal or cellcular and injected intramuscularly with different dosages bursin which gain through ultrafilter. lt is proved that bursin of chickens and ducks can both shorten the time of antibody induced against ibdv, raise the level of serum antibody. they make chickens obtaining strong immunocompetente in a short time. agp liters of the group of infecting 0. 4mlcbs + ibdv of germinal and 0. 8mlcbs + ibdv of cellcular or 0. 8mldbs + ibdv of germinal and cellcular are higher than immune control group about 2 liters averagely. the chickens were inoculated with ibdv live vaccine mixed with the different dosages of lyophilized bursin by the eye drop method. the results sugest that cbs or dbs of different dosages can both improve the antibody inducation to different age chickens against ibdv. they may also alleviate the immunological injury of activated virus to bursa of fabricius. and promote the repairation of the lesion. it can be found that bs can raise body weight gain and feed coversion ratio
將超濾獲得的法氏囊活性肽分別以不同劑量肌肉注射21日齡spf雞,同時頸部皮下注射ibd胚毒或細胞毒滅活苗,結果表明:雞、鴨法氏囊活性肽都能夠縮短ibd油苗誘導產生抗體的時間,提高抗體水平,使雞可以在比較短的時間內獲得堅強的免疫。 0 . 4mlcbs胚毒組和0 . 8mlcbs細胞毒組或0 . 8mldbs胚毒和細胞毒組的agp抗體滴度平均比免疫對照組高2個滴度。將法氏囊活性肽與ibd活苗聯合免疫雞,結果表明:不同劑量的cbs和dbs都可以對不同日齡雞ibd抗體的產生有不同程度的促進作用;還可以減少弱毒對雞法氏囊組織的損傷,加快其修復。Embryo culture of taxus chinensis pilger rehd. and t. brevifolia nutt. in vitro
