The relationship between Discocotyle sagittata intensities and host length, weight and specific anti-parasite antibody titres was studied in 3 year-classes of farmed rainbow trout Oncorhynchus mykiss and brown trout Salmo trutta at the end of the annual transmission cycle.

对一年一度洄游季节末期的三周龄养殖虹鳟和褐鳟进行寄生虫检测，研究Discocotyle sagittata感染强度与宿主的体长、体重、特异性抗寄生虫抗体滴度之间的关系。

Results The expression of the Mahoganoid protein and its mRNA was showed by brown staining and observed in the Leydig cells, spermatogonia, primary spermatocytes, spermatids, Sertoli cells, and peritubular myoid cells of testicular tissues and principal cells, basic cells and epithelial cells of epididymal tissues.

结果1。免疫组化法检测Mahoganoid蛋白的实验结果显示的棕色阳性信号可见于各天龄段大鼠睾丸的生精细胞、支持细胞、间质细胞和管周肌样细胞以及附睾输出管的高柱状、低柱状上皮细胞和附睾管的上皮细胞、主细胞、基细胞。其中Mahoganoid蛋白主要表达于胞膜和胞浆。

The greatest efficiency in Agrobacterium-mediated transformation of lettuce cotyledons(2～3 days-old) was obtained by 10-time dilution of Agrobacterium cells, 15-min inoculation time,1-day pre-culture,4-day co-culture and without AS using the MS(Murashige and Skoog\'s,1962) medium supplemented with 0.2 mg/L 6-benzylaminopurine,0.1 mg/Lα-naphthaleneacetic acid,100 mg/L Kan and 500 mg/L Carb,.

在农杆菌介导的皱叶生菜子叶(2～3 day苗龄)转化试验中，采用含BA 0.2mg/L，NAA 0.1 mg/L，Kan 100 mg/L，Carb 500 mg/L的MS培养基，最优的转化条件为农杆菌稀释倍数为10倍，预培养时间为1 day，共培养时间为4 day，浸染时间为15 min，不添加乙酰丁香酮。

Calli were induced at a high frequency of 76.4±3.2% from petiole explants excised from two-month-old plants on Murashige and Skoog medium supplemented with 5.37 μMα-naphthaleneacetic acid and 4.44 μM 6-benzyladenine.

采用2个月苗龄植株的幼叶柄为外植体，接种於附加5.37μMNAA和4.44μMBAMS培养基，愈伤组织诱导频率高达76.4±3.2%。

This experiment take one-day-old chickens as the object of study, we apply cell raise technologyand MTT method, the indirect enzyme-lined immunosorbent assay, the immunity enzymehistochemistry methods andα-naphthyl acetate esterase etc..

本实验以1日龄雏鸡为研究对象，应用细胞培养技术和MTT法、间接酶联免疫吸附实验、免疫酶组织化学和组织酸性α-醋酸萘酯酶染色法等方法。

Results RARa mRNA and RARg mRNA were both expressed abundantly in fetal adrenal neuroblastic cells.

结果 在胎儿肾上腺神经母细胞中，RARa mRNA、RARg mRNA明显表达并逐渐增强，19周龄后则急剧下降。

The results showed that in the control and experimental groups, HMGB1 immunoreactivity was all diffusely distributed in the cytoplasm of neuroepithelial cells and mesenchymal cells surrounded the neural tube at 8,16 and 24 hours after water bath treatment.

将孕鼠随机分为实验组和对照组，分别于水浴处理后8、16、24、40、64 h（相当于胚龄第8、8.5、9、9.5、10.5 d）处死孕鼠，剖腹取鼠胚，制备石蜡切片，应用免疫荧光染色技术检测NTDs发生过程中HMGB1在神经上皮细胞中的表达变化。

BFGF immunoreaction was detected at 3-weeks' embryonic neuroepithelium, and remained positive throughout various development a l stages examined, whereas NGF immunoreaction appeared after 4-weeks. The expres sion varied gradually with the development of embryos. There was no specific EGF immunoreaction in all tissues and stages examined. The occurrence and distribut ion of FGFR, NGFR and EGFR were similar, and their expression altered with the development.

结果显示bFGF和NGF的表达时序不同，b FGF阳性细胞出现较早，在所检测的各个发育阶段均呈阳性表达，而NGF出现较晚，随着胚龄增加，免疫阳性着色逐渐增强，bFGF分布较NGF广泛，而EGF在所检测的各个发育阶段均呈阴性。flg、TrkA、EGFR表达时序和分布相似，三者在所检测的各个发育阶段均呈阳性。
