As the strain sensing element of a structural health monitoring, the study and the application of the fibre-optic bragg grating (FBG) have been widely accepted. The accuracy of the FBG sensor is highly dependent on the physical and the mechanical properties of the strain interface transferring characteristics among the layers of bare optical fibre, protective coating, adhesive layer and host material. 更多
 The recent opportunity of examining the faecal material of the water-scorpion Leccotrephes japonensis revealed a flagellate which had not previously been described from this host. After fuller investigation I found that it is a species new to science and should be referred to the genus Retortamona; I have named it Retortamonas leccotrephae sp. nov.The specimens of Leccotrephes japonensis used for studies on the parasitic flagellate R. leccotrephae, were collected from ponds on the outskirts of Shanghai, China.... The recent opportunity of examining the faecal material of the water-scorpion Leccotrephes japonensis revealed a flagellate which had not previously been described from this host. After fuller investigation I found that it is a species new to science and should be referred to the genus Retortamona; I have named it Retortamonas leccotrephae sp. nov.The specimens of Leccotrephes japonensis used for studies on the parasitic flagellate R. leccotrephae, were collected from ponds on the outskirts of Shanghai, China. Apart from studying the living flagellates, at the same time stained specimens were prepared for the detailed study of various structures. These specimens were fixed either in Hollande's or in Schaudinn's fluid; stained in Heidenhain's haematoxylin, and destained in 2％ aqueous phospho-tungstic acid. Moskowitz' (1950) modification of the Protargol impregnation method was also used for staining.In the living state, the flagellare has a slender, slipper-shaped trunk with an anterior dorsal flexure. The mean body size, exclusive of the posterior spike, is 12.8μ×4.8μ. The length of the slender posterior spike varies from 4.6μ to 15.8μ. There are two flagella of unequal length. The longer one extends forwards and lashes rapidly, causing the animal to rotate and to pursue a special course. The shorter flagellum is directed backwards and usually lies in the cytostome; it moves in an undulating manner.In fixed and stained preparations, the flagellates, not including the posterior spike, show a size-range of 6.2×2.2μto 15.6×5.4μ, with a mean of 11.9×3.4μ. The spike varied from 4.6μ to 13.6μ long, with an average length of 11.2μ. In general, a normal specimen of R. leccotrephae has a slender body; the anterior portion is narrower than the postcerior, and is markedly bent as shown in the living indivi.duals. The posterior portion of the body usually has a dorsal convexity, and the widest region is located near the two-thirds of the body-length from the anterior end.Near that edge of the nuclear membrane lying next to the cytostome, there are two minute, but separate, basal granules which give rise to the two flagella. The anterior flagellum is about as long as the body proper: much longer and more slender than the posterior flagellum, which usually lies within the cytostome, and commonly shows a series of two or three undulations; it often stains more deeply than the anterior flagellum.In hematoxylin preparations the nucleus is well stained, and clearly shows a layer of chromatin granules lying against the nuclear membrane, and a large central endosome, composed of a mass of granules.The cytostome is a large structure in this animal. It usually occupies about twothirds of the total length of the body proper. Along the margin of the cytostome there are two deeply staining fibres, the one on the right margin is longer than that on the left.Both the precystic forms and cysts of R. leccotrephae have been observed. The body of precystic individuals which are preparing to encyst, becomes smailer and rounds up; meanwhile, the chromatin of the nucleus condenses and forms a deeply staining endosome. The anterior flagellum is still disposed freely, and no cyst wall has as yet been formed. The border-line of the cytostome is distinct, but the two basal granules are visible only in favourable preparations. The mature cysts are nearly peanut-shaped, and are about twice as long as wide. In the stained specimens they are about 4.6μ long and 2.4μ wide. The cyst wail is of uniform thickness, and the nucleus is visible at one end. The other conspicuous structures within the cyst are the two flagella and the cytostomial fibres, which are arranged as they are in the trophozoite, except that the anterior flagellum is here directed posteriorly.DISCUSSION & SUMMARYIn its general body-form, R. leccotrephae closely resembles Mackinnon's R. agilis ('11) from crane-fly larvae, and also Corradett's R. gryllotalpae ('37) from the mole cricket, but it is especially like Geiman's R. caudacus ('32) from the aquatic larvae ef certain beetles. 红娘华蛐的身体结构,一般与Mackinnon所述的R.(Embadomonas) agilis和Corradetti所述的R.grillotalpae相似,特别近似Geiman所述的R.caudacus(图15,16)。但红娘华蛐有大约等於体长2/3的大胞口,和长於或等於体长的针状尾巴,而且无论在生活时或固定染色後,头部均向背後扭曲(此较图1和15)。这些特性,显然与过去文獻中所记载的种类不同,故(氵夬)定为蛐属——新种。 Chang Shan, the subterranean portion of Dichroa febrifuga Lour.

(family Hydrangeaceae), and Shu Chi, the leafy tops of the same plant, have been used in Chinese medicine more than two thousand years, but their antimalarial action has been scientifically proved and constituents investigated only in recent years. A brief account of their history, botanical source, plant habit, cultiva-tion and collection and a detailed description of their sensory, macroscopical and microscopical characters are given. The important diagnostic features of Chang Shan are:-vessels with long oblique end-plates having well-marked scalariform perforations and often containing tyloses; septate xylem-fibres; idioblasts containing bundles of acicular crystals embedded in mucilage; thick-walled pericyclic fibres; the deep-seated origin of the cork. A well-marked medullary sheath of thick-walled, lignified and pitted parenchyma occurs in the pith of both the stem and rhizome. The important diagnostic features of Shu Chi are:-thick-walled, warty, unicellular trichomes; paracytic (rubiaceous) stomata; epidermal cells with pitted anticlinal walls and finely striated cuticle; water-pores in the teeth of the leaf; idioblasts with bundles of acicular crystals em-bedded in mucilage; droplets of fixed oil in most of the cells of the leaf; thick-walled pericyclic fibers from the stem as well as deep-seated cork and characteristic vessels as seen in the subterranean organs. The significance of some of the microscopical findings as a further illustration of the connexion between anatomy and taxonomy is also discussed. 1.常山是八仙花科植物黄常山Dichroa.febrifiuga Lour.的地下部分,而蜀漆是本植物的带叶枝梢,两者都有抗疟的效力。2.木文简单地介绍了前人研究常山的情况,然後详细地描述了,常出和蜀漆的性状和组织构造;并指出了某些组织特徵在分类学上的意义。3.常山的重要特徵是:(1)导管,末梢壁长而斜置,有显著的梯纹穿孔,并常含有侵填体;(2)分隔木纤维;(3)含草酸钙针晶束的异细胞,针晶束外有粘液包围;(4)厚壁的中柱梢纤维;(5)内生性的木栓层。根茎和茎的根部周围有显着的根鞘,根鞘由厚壁的木化细胞所成,壁上有单纹孔。 4.蜀漆的重要特征是:(1)厚壁有疣的单细胞毛;(2)平轴式气孔;(3)垂周壁上具有纹孔的表皮细胞;(4)叶绿锯齿上的水孔;(5)含草酸钙针晶束的异细胞,针晶束外有粘液包围;(6)脂肪油珠,存在於大多数叶肉细胞中。此外、并有由茎中来的厚壁的中柱鞘纤维和内生性的木栓层,以及特殊的梯纹导管,其形状和在地下器官部分所见的一样。 The observation of Koshtoyantz that urea has beneficial effect on muscle fatigued by indirect stimulation, has been confirmed.

The observation of Koshtoyantz that urea has beneficial effect on muscle fatigued by indirect stimulation, has been confirmed. This"defatigue" effect really only represents a removal of conduction block at the neuromuscular junction. On fatigue of the muscle fibres itself urea has no ameliorating effect. To obtain the above mentioned"defatigue" effect of urea requires rather strict experimental conditions; in particular, the Ringer used to soak the muscle and to prepare the urea solution must contain a small amount of phosphate and bicarbonate and a relatively low concentration of calcium. Cysteine not only has no similar"defatigue" effect, but when present together with urea even tends to suppress the"defatigue" effect of the latter. Another contrast between urea and cysteine is that while cysteine can remove the neuromuscular block due to cadmium chloride, urea can not. Neuromuscular block resulting from lack of sodium ions or a certain ionic inbalance in the medium can also be partially removed by urea. Soaking in urea solution causes the muscle to respond repetitively to single stimulus, whether indirect or direct. The hypothesis that the"defatigue" effect of urea on the muscle results from the release of the SH groups of some proteins, has been examined and found to be at present very uncertain.

Feng for guidance and encouragement throughout this work. 對於肌肉在接連的間接刺激中所發展的疲乏,脲有解除作用,半胱氨酸沒有。這實際上只是對神經肌肉接頭的傳導阻遏的解除,對於肌纖維本身的疲乏,脲並不能減輕。要得到脲對於神經肌肉接頭的疲乏的解除作用,試驗須具備一定的條件,特别是用以浸潤肌肉和配製脲溶液的任氏溶液,必須含有少量的重碳酸根或磷酸根離子並有適宜的鈣離子濃度。脲的處理能使肌肉纖維對單個刺激作重複反應,不論刺激是間接的或直接的。 對於由於電解質缺乏或不平衡而起的神經肌肉接頭的傳導阻遏,脲亦有解除作用。但氯化鎘引起的傳導阻遏,脲不能解除,而半胱氨酸則能。 關於脲作用的機制,本文有所討論,指出釋放硫氫基的假說能否成立,尚属疑問。 << 更多相关文摘
