The biological activities of the metal complexes of derivatives of benzaldehyde nitrogen mustard were investigated against 〓,〓 and SMMC-7721 cell lines. The interesting results were found. When the non-activity ligand combines with cobalt and nickel , the complexes have good antitumor activity, while active ligand binds to the metal, the complex has no activity, indicating there are synergic effect and counteraction between the metals and the ligands.

Histological structures of bursas of Fabricius were observed at the different developmental stages from chicken embryoes to chickens. The results were as follows. The bursa of Fabricius began to develop on the 13th day of post-hatching and its cell aggregated into the nodosity clique underneath the epithelium mucosae. On the 15th day of post-hatching, those cell cliques were surrounded by the flat epithelium and formed the basic structure of folliculus lymphaticus. The number of lymphocytes in the folliculus lymphaticus increased gradually, and the medulla and cortex of a majority of folliculus were not discriminated obviously. Until on the 7th day for chickens, the medulla and cortex of folliculus formed completely and the number of folliculus increased significantly. From 21 to 35 days old, the folliculus lymphaticus transformed from polygon into rectangle. Mucosa epithelial cells increased gradually and their cytoblasts arranged compactly into aline in the basilar part on the 35th day.

成年人学英文的第一课和第二课刊出后,有数位读者写E-mail给我。有一位说道:「一篇文章的每一个单字都查到解释了,但整篇文章就是看不懂,怎麼办?」另一位说:「我的文法很差,没办法写完整的英文句子,要如何补救?」当发音和字汇都掌握住学习要领之后,剩下的就是「读」和「写」了,这才符合学习英文的正确步骤:听→说→读→写。台湾传统的学习方式由「写」开始,再「读」,然后才「说」,最后再去补救「听」力,可以说是背道而行,难怪效果不彰。那麼学习「读」的要诀是什麼呢?当然最重要的是能够了解整个句子的涵义。记得初中的时候背了很多文法规则,考试的分数虽然很高,但是对「读」的能力没有帮助。连那个时候流行的「英语九百句型」,也从来没有耐心读完过。然而我们今天能够看懂中文的文章,难道是因为我们熟悉中文的文法吗?答案是否定的。同样地,一个美国人虽然能阅读报纸,但是要求他做「英文文法分析」,他可能也会傻眼。英文的句子其实不需要去靠文法书中的规则去了解,文法书只应当作参考书,在有疑惑的时候才去查阅。平常应养成「约定成俗」的习惯,就是看别人怎麼用,然后「依样画葫芦」,日积月累,文法规则就化为无形了。因此,要训练「读」的技巧,不应该是靠文法规则,而是要多读。但是在读之前,要具备「了解句子」的基本能力,这就是我们的第三课─了解英文句子的要诀。了解英文句子的关键,在於先抓住「主词」和「动词」。看到一句很长的英文句子,不要害怕:先找主词,再找动词。动词如果是「及物动词」,再去找「受词」。主词、动词、受词之外,剩下的通通当做修饰语,有的修饰主词,有的修饰动词,有的修饰受词,有的修饰全句;任何两个完整的句子都可以用连接词连接起来。以上简单几句话,就是了解英文句子的基本观念。了解英文句子的第二步是熟悉英语的五种基本句型,其中前两种与不及物动词有关,后三种与及物动词有关。以下的句子中,用大括号表示{主词}或{受词},中括号表示,剩下的部份都是修饰语。第一种与不及物动词有关的基本句型叫做「简单不及物句型」(Intransitive Verb,简称I),请背住以下五个句子

为加强房地产产权产籍管理走出了一条新路。我市房产测绘体制改革是伴随着社会主义市场经济的建立和发展逐步铺开的。80年代中期,我市房屋产权登记开始恢复时,尚未建立专业的测绘队伍,在房屋产权确认中作为重要依据的图、档以及房屋面积都是由产权登记人员用皮尺到现场手工丈量确定。1985年房屋普查结束后,原普查人员组建成市测绘处,负责全市房产测绘工作,人员经简单培训后上岗,测量停留在手工皮尺操作上,技术没有规范,人员缺乏专业知识。
