Nigra, B. oleracea and B. carinata belonged to class 2A according to the classification of karyotypes by Stebbins (1971). According to Levitzky's and Stebbin's view, the more asymmetric karyotype a species has, the more evolved it is. Therefore, B. campestris is the furthest evolved species among the elementary species, and B. juncea and B. napus the furthest among the amphidiploid species. Compared with the previous reports, there is no any cytoplasm in the chromosome sample prepared using this protocol which is very useful for the karyotype analysis, as well as the FISH research on Brassica species.

对上述研究结果分析表明：（1）芸薹属复合种是由基本种相互杂交而成；（2）B基因组与A或与C基因组亲缘关系较远，而A和C基因组亲缘关系较近；（3）芸薹属复合种在演化过程中，发生了染色体结构上的重排现象；（4）芸薹属复合种演化过程中，rRNA基因位点发生了减少；所获结果与国外同类报道相比表明：国内的白菜型油菜存在新的rRNA基因位点，即rRNA基因在芸薹属同一物种不同的品种间具有多态性；有关这类研究国内尚未见报道。

There are four kind of isoforms of endothelin in human and other mammals named ET-1, ET-2, ET-3 and ET-β, which are slightly different in construction and pharmacological effect. In human beings, ET-1 is the dominative subtypes. ET-1 remains in blood at a low level about 5ng per liter on physical state. It is synthesized, stored, released and metabolized locally. The half-life of ET-1 is about 1 hour. ET-1 is the most potent vasoconstrictive factor till now, and it is more functional in vein than in artery. In vascular bed, there are two kind of ET receptors. Type A mainly located in smooth muscle cells, whereas type B in endothelial cells. The latter can stimulate intimal hyperplasia via a parasecretion way and activate some oncogenes such as c-fos and c-myc and then enhance their expression. These alterations result in constriction of blood vessels, thus the SMC steps into proliferate state from silent state.

人及哺乳动物体内有四种结构及药理学性质略有差异的异物体，分别为ET-1、ET-2、ET-3、ET-β，而在人主要是ET-1，在生理条件下，ET-1在血浆中含量较低，约为5ng〓，故ET-1不是一个循环激素，而是局部合成释放，局部起作用的活性物质，半衰期约1小时，ET-1是目前已知的最强的血管收缩剂，对静脉的作用比动脉强，在血管床，ET受体有A、B两型，A型主要分布在平滑肌细胞，B型主要分布在内皮细胞，它可以通过旁分泌途径刺激内膜增生，具有有丝分裂原效应，可以激活某些癌基因如C-fos、C-myc使其表达增强引起血管收缩，使静止期SMC进入增殖期，还可以通过信号传导途径，与bFGF、GTF-β、PDGF等生长因子协同作用，起共有丝分裂原作用。

Results The neurological defects score was singificiant lower in D group (41.50±8.18) than that in group A(82.20±8.08), B(63.60±6.22) and C (61.00±6.58)(all P.01). Compared with groups A, C, group D showed that the cellular nucleus was shrinkaged slightly, the gap of cells was nomal roughly and the degree of rarefaction in neurofibra net was not serious under the light microscope. Under the electron microscope, the neuron was degenerated, the cellular membrane was integrated and the plastosome was swelled lightly in the group D. The physiological demage were slighter in D group.

结果 D组神经功能缺损评分(41.50±8.18)明显低于A组(82.20±8.08)、B组(63.60±6.22)和C组(61.00±6.58)（均P.01）；光镜下D组神经细胞核轻度皱缩，细胞周围间隙大致正常，神经纤维网疏程度不严重；电镜下D组神经元轻度变性，细胞核无皱缩，核膜完整，线粒体轻度肿胀；脑组织病理损害程度较B组和C组明显减轻。

If only enough rope is available for a belay from one bank, A crosses as above. C ties into the main belay rope and also ties on alight retrieving cord held by Band is belayed by A. This retrieving line is necessary since it would probably be impossible to throw the rope back to B after C crosses.

如果绳子的长度只够从一边作确保，A仍像上述过溪，C要套入胸部绳圈中由A作确保工作，同时要有另外一条回收绳连接到B手上作主绳的回收工作，这条回收绳是必要的因为C过溪之后几乎不可能将主绳抛回去给B。

Methods 123 clearly diagnosed anxiety neurosis sufferers were randomly divided into group A,group B and group C(psychotherapy and drug treatment).

经8周治疗后分别进行治疗前后比较。结果焦虑症多伴有恐惧、抑郁、人际敏感、强迫、躯体化等。治疗效果以C组最佳，症状缓解率分别为：A组43·9%、B组57·5%、C组88·6%，C组与A、B组比较差异有统计学意义(P·01)。

The results showed that 9 pathogen collections of Sporisorium reilianum were divided into 3 pathogenic types in which there were type A with high pathogenicity, type B with moderate pathogenicity and C with weak pathogenicity. Type A were originated in most important corn-grown areas including Changchun ,Jilin,Gongzuling and Changling where corn head smut usually occurs severely, type B were collected from Siping,Tonghua ,Songyuan,Yanbian, and type C were collected from Baicheng where corn head smut usually occurs very lightly.
