And then adding NAA at low concentration in MS was used to give rise to roots. We also found that lower level of hormone could control effectively browninng and vitrifaction during the culture and G1 n (6mg/L) and AgNOj (2mg/L) supplemented in shoot induction media could improve the shoot information rates apparently (about90%).The whole period of plant regeneration from leaflets of peanut could be divided as five steps: germination - shoot induction -shoot elongation-rooting- tranplant.

用1／2MS培养基萌发花生种子，9-10d后，从无菌花生苗上切取幼嫩叶片中部为外植体。2500Lux光照和27±1℃条件下，在诱芽培养基(MS+BA3mg／L+NAA0.8mg／L+AgNO_32mg／L十Gln 6mg／L)培养12-14d即可观察到明显芽点或瘤状突起，较前人报道的培养时间大大缩短了，4w后芽点进一步发育成丛生芽，芽诱导率达90.2％，每个外植体平均产9个丛尘芽，然后转至培养基MS+BA3 mg／L+AgNO_32 mg／L上诱导芽的伸长，3-4w后可长至3-4cm，切下带有2-3片叶片的幼芽移至生根培养基(MS+NAA0.8mg／L+AgNO_32mg／L)，1w后切口处可见白色不定根形成。

Nine sheep with permanent cannular were randomly divided into three groups, and the roughage quality was evaluated by Grading Index of roughage. Three kinds of roughages were used in the trial diets which had the same ratio of roughage to concentrate of 8∶2 to adjust the different roughage qualities. Three qualities of diets included? higher quality roughage (GI=2.89 MJ), middle quality roughage (GI=1.73 MJ) and lower quality roughage (GI=0.65 MJ),?

试验将带有永久瘤胃瘘管的9只绵羊随机分成3组，以粗饲料分级指数GI为指标对粗饲料品质进行划分，在精粗比为2：8条件下配制3种混合日粮，形成含高GI粗饲料日粮组（H组，粗料GI值＝2.89）、含中GI粗饲料日粮组(M组，粗料GI值＝1.73)和含低GI粗饲料日粮组(L组，粗料GI值＝0.65)。

It is currently considered that the functional defects of mitotic checkpoint and centrosome abnormalities may play important roles in the development of aneuploidy in tumor cells.

近年来研究显示：细胞有丝分裂检查点功能缺陷和中心体异常可能是肿瘤细胞CIN形成的重要原因，但这一推测还没有在包括OSCC在内的人类大量实体瘤中得到全面证实。

The purified immunoglobulins were effective in the inhibition of endothelial cell adhesion, proliferation and angiogenesis in chick chorioallantoic membrane in vitro, and in anti-tumor activity by the adoptive transfer in vivo.

将该抗体纯化后，纯化的免疫球蛋白可以有效地抑制体外内皮细胞的粘附、增殖和鸡胚绒毛尿囊膜的新生血管形成，体内过继输入治疗亦可引起抗瘤效果。

Osteoblastoma is an uncommon bone tumor, characterized cytologically by an abundant presence of osteoblasts, and a highly vascular matrix with osteoid tissue and bone formation.

What was observed under a light microscope included: tumor cells were mulberry and micropapillary shaped or were of glandule tubular arrangement; there was obvious interspace between cancer nest and neighboring areas; micropapillary was empty of fiber blood vessel axes, with micropapillae floating freely in spongy spaces and separated by fibrous septa.

光镜下特征性表现为肿瘤细胞呈桑椹状、微乳头状或小腺管样排列，癌巢与周围间质形成明显的空隙，微乳头缺乏纤维血管轴心，每个微乳头细胞团和周边的纤维组织均存在无细胞的间隙样结构；瘤细胞CerbB-2、CgA和EMA。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
