稀有濒危植物珊瑚菜的染色体特征及其演化地位

首次分析了珊瑚菜（ Ｇｌｅｈｎｉａ ｌｉｔｔｏｒａｌｉｓ） 根尖体细胞染色体组型。其核型公式为２ ｎ ＝ ２２＝ １８Ｍ ＋ ４Ｓｍ （２Ｓａｔ） , 核型不对称性属于２Ａ 型。据此讨论了该属在我国伞形科稀有濒危单型属和当归亚族中的演化地位。     

广西桂林菜子岩剖面中-上泥盆统界线附近的珊瑚动物群

中泥盆世吉维特期至晚泥盆世弗拉期早期,桂林菜子岩剖面处于浅水台地与较深水盆地过渡相区,因而含有较丰富的底栖生物(珊瑚、腕足类等)和浮游生物化石,包括有重要的牙形石带分子,因此该剖面是一重要的浅水相区与较深水相区对比的参考剖面。总体来看,菜子岩剖面的吉维特期晚期较弗拉期早期的四射珊瑚及床板珊瑚均要常见,其中四射珊瑚Truncicarinulum广泛分布,吉维特期晚期(自牙形石Schmidtognathus hermanni带至吉维特期结束)可以称为Truncicarinulum liujingense-Planocoenites guilinensis组合,但其主要特点则是以含有丰富的床板珊瑚为特征。弗拉期早期则以Phacellophyllum的较广分布为特点,可以称为Phacellophyllum stereoseptatum四射珊瑚动物群。文中共描述和图示了5属8种四射珊瑚和9属10种床板珊瑚。其中四射珊瑚有一个新种:Phacellophyllum stereoseptatum Liao and Ma sp.nov.;床板珊瑚有2个新种:Crassialveolites gaoshangtianensis Deng and Ma sp.nov.,Planocoenites guilinensis Deng and Ma sp.nov.。

论四射珊瑚征珊瑚属 Charactophyllum Simpson,1900

对Ｃｈａｒａｃｔｏｐｈｙｌｕｍ作了全面的回顾整理,记述了本属的骨骼构造,在此基础上讨论了其定义范围和时空分布及有关的分类问题。Ｃｈａｒａｃｔｏｐｈｙｌｕｍ的隔壁为板状隔壁而非包珊瑚型隔壁,由波状弯曲的单列单晶榍组成,单晶榍整体呈半扇形排列而非扇形排列,隔壁光滑或发育微弱的榍凸（ｃａｒｉｎａｅ）而无典型的横耙状榍凸（ｙａｒｄａｒｍｃａｒｉｎａｅ）,鳞板半扇形排列而不是扇形排列。本属分布仅限于北美和华北的晚泥盆世早期。Ｃｈａｒａｃｔｏｐｈｙｌｕｍ隔壁中单晶榍由放射状排列的不规则短轴晶柱和晶针组成,横列构造鳞板和横板均由晶板型层状骨骼组成。本属骨骼微细构造的重要特征具有奥陶志留纪与石炭二叠纪四射珊瑚之间的过渡性质。表明四射珊瑚骨骼微细构造演化趋向稳定,是追索演化的重要线索,在较高级别的分类中具有重要意义     

论四射珊瑚包珊瑚科（AmplexidaeChapman,1893）的分类

讨论了包珊来龙去脉 科（ＡｍｐｌｅｘｉｄａｅＣｈａｐｍａｎ１８９３）的分类。把包珊瑚型隔型限于仅在外端连续,向轴部变薄呈短而低的脊状,纵向呈下连续的着生于横板之上。包珊瑚型隔壁的微细构造以层状骨骼为主,其轴部有时可出现非晶榍型纤状之骨骼,包括晶粒和短轴晶柱。

SPHINGOLIPIDS AND PHOSPHOLIPIDS IN MICROSOMES AND MYELIN FROM NORMAL AND PATHOLOGICAL BRAINS

—Myelin and microsomes were separated from human cerebral white matter and cortex respectively using the technique of 15% caesium chloride and their sphingolipid and phospholipid contents estimated. Normal brains as well as cerebral material from cases of metachromatic leucodystrophy, Krabbe's disease and Tay-Sachs’disease were studied. Gangliosides were not present in normal myelin but were found in microsomes and in myelin from the pathological material. The ratio of cerebroside to sulphatide in myelin was 4 to 1 in normal, 1 to 20 in metachromatic and 7 to 1 in Krabbe's disease. The results in the human material are briefly discussed.     

HIGH AND LOW DENSITY WATER AND RESTING,ACTIVE AND TRANSFORMED CELLS

Resting and active states of cells are described in terms of the expectation, derived from experiments with aqueous polymers, that they contain two modified forms of water: high density, reactive, fluid water and low density, inert, viscous water. Low density water predominates in a resting cell and is converted to high density water in an active cell. It is proposed that switching from one state to another is an integral part of cellular function. When this ability is lost cells are transformed either to a state of rigor or to a hyperactive state in which they no longer depend upon external signals.
