嗜热蓝藻鞭枝藻藻胆体的分离及其光谱特性的研究

从嗜热蓝藻鞭枝藻（Ｍａｓｔｉｇｏｃｌａｄｕｓｌａｍｉｎｏｓｕｓ）中分离出藻胆体，并对其光谱特性进行了研究．完整藻胆体的室温荧光峰位于６７３ｕｍ，７７Ｋ荧光发射光谱中只有一个峰，位于６８５ｕｍ，解离的藻胆体的７７Ｋ荧光峰位于６８３ｎｍ，并在６６６ｎｍ和６５０ｎｍ处形成小的荧光发射峰．严重解离的藻胆体室温荧光峰位于６４５ｕｍ，７７Ｋ荧光峰位于６４４ｕｍ，６８３ｕｍ荧光显著下降，成为小峰．完整藻胆体与解离的及严重解离的藻胆体的吸收光谱没有显著差别，吸收峰位于６２２ｕｍ，在５８０ｕｍ处有一吸收肩．

C-S-H中Al3+离子的固溶对表面吸附碱量的影响

研究了Al3+离子的固溶对C-S-H表面吸附Na+离子量的影响.实验结果表明,Al3+离子固溶于C-S-H结构中将使C-S-H表面所带的负电量增大,因而也就增大了C-S-H表面对Na+离子的吸附能力.     

钠快离子导体Na_(2.5)Zr_(2-x)Ti_xSi_(1.5)P_(1.5)O_(12.0)系统的研究

钠快离子导体Ｎａ_２．５Ｚｒ_２－ｘＴｉ_ｘＳｉ_１．５Ｐ_１．５Ｏ_１２．０系统ｘ＝０－２．０的化合物，由Ｎａ_３ＰＯ_４－ＺｒＯ_２－ＺｒＰ_２Ｏ_７－ＳｉＯ_２－ＴｉＯ_２为反应的起始原料，在９００℃－１２００℃的高温下反应数小时至二十小时制得。系统化合物的相变关系已探明，并测定了有关的单纯相在不同温度下的导电率以及电导激活能。相当于起始组成为Ｎａ_２．５Ｚｒ_１．０Ｔｉ_１．０Ｓｉ_１．５Ｐ_１．５Ｏ_１２．０的单纯相（标为２．５１相）在３００℃时的导电率σ３００＝１．８５×１０－２（Ω·ｃｍ）－１，其电导激活能为２３．６４ｋＪ／ｍｏｌｅ，相当于起始组成为Ｎａ_２．５Ｔｉ_２．０Ｓｉ_１．５Ｐ_１．５Ｏ_１２．０的单纯相（标为２．５２相）在３００℃时的导电率σ３００＝０．４６×１０－２（Ω·ｃｍ）－１，其电导激活能为２８．８９ｋＪ／ｍｏｌｅ．     

Influence of hydrochlorothiazide on the pain threshold and on the antinociceptive activity of morphine,in rats

Summary Hydrochlorothiazide, acutely injected in rats, has a weak analgesic activity per se and potentiates and prolongs the antinociceptive effect of morphine.This work was supported in part by grants from Consiglio Nazionale delle Ricerche, and by Ministero della Pubblica Istruzione, Roma.     

Der Einfluß der Nebenniere auf die Kreislaufwirkung des Adrenalins

Summary Traces of nor-adrenaline restore the vascular action of adrenaline altered in epinephrectomized dogs to the reaction of the normal animal. Therefore it is claimed that the adrenals discharge one or several substances into the blood stream, which are necessary for the usual peripheral vascular action of adrenaline. Further investigations are in progress.     

The crystal-like anatomical uniformity of the striate cortex

The visual field is topographically mapped onto the primary visual cortex (V1), forming a retinotopic map which is far more detailed for the foveal regions than for the periphery. We found that receptive field (RF) size in monkey V1 increases with eccentricity, and that a 1—2 m² V1 region contains roughly a complete set of machinery necessary to analyze a visual-field area whose size is about that of the RFs of the cells. This allows V1 to be anatomically uniform, and is in sharp contrast with the retina.
