报道采自甘肃文县的东方法老蛛雌蛛,为该种雌蛛的首次记述。     

狼蛛,蟹蛛和跳蛛

狼蛛、蟹蛛和跳蛛分别是蜘蛛目中三个科的蜘蛛的通称。这三类蜘蛛包括了我们日常见到的游猎型蜘蛛的大部分种类,它们在帮助人类消灭害虫中所起作用也较大,所以作为动物学教学中的例子加以介绍。 (一)狼蛛狼蛛在地面或植物上疾驰,凶狠如狼,故名。体长3-25毫米,但多数种类在5-8毫米间。体色多黄褐色,不鲜艳。8眼,排成三列。前列4个小眼,中、后两列各2个眼,较大;后列两眼的间距稍大于中列两眼的间距(图1左)。卵袋扁球形,由两片半圆形丝膜缝合而成。卵袋挂在母蛛腹部后端的纺器上,由母蛛随身携带。幼蛛孵出后不分散,而是爬伏在母蛛腹部

沙门菌CWDMs苹果酸脱氢酶的检测

目的：了解沙门菌细菌壁缺陷突变株（CWDMs）的生物氧化及遗传特点和探讨细菌壁缺陷变异的性质与机制。方法：采用PAGE电泳法和分光光度法检测伤寒沙门菌和甲型副伤寒沙门菌及其CWDMs和伤寒沙门菌粗糙型和苹果酸脱氢酶（MDH）同工酶的活性与类型。结果：伤寒沙门菌和甲型副伤寒沙门菌的细菌型和伤寒沙门菌粗糙型经PAGE电泳可见一条MDH同工酶带,CWDMs电泳后可见两条MDH同Ⅰ酶带,在CWDMs的MDH中有一条泳动速率与细菌型及粗糙型的相同,另一条则较快。分光光度法检测证实。细菌型与粗糙型的MDH活性相似,CWDMs的MDH活性则明显较低。结论：CWDMs保留了与亲代细菌型一致的MDH和形成了一种新的MDH,并且其MDH的活性已显著降低,此特性可能与CWDMs生物氧化特性的改变有关。

ULTRASTRUCTURE OF AUXIN-INDUCED TUMORS OF THE COLEORHIZA-EPIBLAST OF WHEAT

When wheat is germinated in high concentrations of certain auxins, the coleorhiza-epiblast grows in an excessive and disorganized manner and resembles a callus. Wheat was germinated in 10⁻³ M indoleacetic acid or in water. There was greater net synthesis of DNA, RNA, and protein in the tumor tissue than in control tissue. Control and tumor tissue was fixed for electron microscopy 1, 2, 3, and 4 days after sowing. In contrast to the controls, many more lipoidal bodies appeared in 1-day-old, auxin-treated tissue and thereafter diminished in number. In 2- and 3-day-old tumor tissue, small membraneous fragments were prominent but disappeared in older tissue. With time, the following changes became progressively more pronounced: cytoplasmic vacuolation, appearance of myelin figures, polyribosome configurations and extensive profiles of rough endoplasmic reticulum, and sloughing of cytoplasmic contents into and accumulation of electron-dense material in vacuoles. Possible factors in susceptibility of certain tissues to tumor formation are discussed.     

MODE OF NUCLEAR DIVISION IN SYNCHRONOUS CULTURES OF CHLORELLA: COMPARISON OF VARIOUS METHODS OF SYNCHRONIZATION

1. Chlorella ellipsoidea was grown synchronously using variouspossible techniques and the mode of nuclear division in eachcase was followed by staining the nuclei according to FEULGEN.
2. A satisfactory synchrony in respect to nuclear and cellulardivision was obtained by starting the culture from a homogeneouspopulation of young and small cells and by discontinuing theillumination at the stage which was called the L₃-stage. Thestarting young cells were invariably mononuclear and the L₃-cellswere either dinuclear or tetranuclear. When the L₃ were incubatedin the dark, they ripened further, and after passing througha tetranuclear stage (referred to as the L₄) divided into fourmononuclear daughter cells which have been called the D_n-cells.The most clear-cut and repetitive synchronous culture was obtainedwhen the culture (in the light) was started from the D_n-cellsand the illumination was discontinued at the L₃-stage untilthe fully ripened cells divided into four each of D_n-cells.
3. An apparently "synchronous" culture was also obtained by themethod of programmed light-and-dark regimen, in which a randomculture is subjected to a regular alternation of light and darkperiods of adequate durations. In this case, however, the cellsat different stages of culture showed irregular nuclear patterns,and the average "division number" of mother cells was not constant,being subject to change between 4.0 and 4.9.

THE EFFECT OF TIME OF APPLICATION OF NITROGENOUS FERTILIZER ON POWDERY MILDEW OF WINTER WHEAT

Applying nitrogenous fertilizer (N) to wheat plants of different ages affected the incidence of powdery mildew, Erysiphe graminis DC, differently. When N was applied before the flag leaf had emerged, the infection-index (number of pustules per 100 sq.cm. of leaf blade) increased to a maximum and then declined. If N was applied after the flag leaf had emerged, the infection-index increased steadily without reaching a peak, and the increased susceptibility was not associated with an increased relative leaf growth rate as when N was applied earlier.
The integral of the number of pustules per unit area with time, and the number of perithecia on the leaves of the main stem, both increased with increasing delay in the application of N. Plants given N in either April or May had at least three times as many pustules as those given N in January. The time when N was applied did not affect the date when perithecia appeared.
After adding N to nitrogen-deficient plants, the already mature leaves which had resisted mildew infection, became susceptible. This change is not associated with changes in the epidermal wall.     

EVALUATION OF EXPOSURE TREATMENT OF BURNS

For purposes of comparison with the occlusive dressing method of treating burns, the exposure method was used in 30 cases—16 of first and second degree and 14 of third degree. Attempt was made to simulate the conditions which might be expected to prevail in mass treatment of burned patients—inadequate personnel and materials. Elaborate measures to immobilize burned areas were not employed.Healing of first and second degree burns was natural and the results satisfactory without further treatment. In third degree burns, skin grafting was necessary after the eschar was removed. Cracking of the eschar several days before time to remove it in some cases of third degree burns necessitated use of occlusive dressings in the last few days before skin grafting was done.The exposure method is considered valuable in circumstances in which saving of time, material and personnel is indicated. Generally it is not suitable for treatment of encircling burns of the trunk or extremities, since maintaining the integrity of the eschar is extremely difficult in such situations.     

甲基胆蒽对蝾螈中胚层分化的影响

前言对哺乳类有引瘤作用的物质,在两栖类的成体中,不论是有尾类(Breedis,1951,1952;和,1954)或者无尾类(曾弥白,1956a),都可以引起恶性瘤肿,虽然瘤肿形成的频率远没有在哺乳类高。对于两栖类幼体,或者正在发育中的胚胎组织,引瘤物质却表现了不同的作用。它们可以引起形态建成的变化。Waddington 和 Needham(1935)将多种多环碳氢化物塞入早期原肠胚的囊胚腔,发现其中几种诱导了神经组织的发生。为了避免塞入法可能引起的机械的影响,沈诗章(Shen,1942)用二苯骈蒽内琥珀酸钠(Na-dibenz-anthracene-endo-succinate)的水溶液处理早期原肠胚的预定表皮,也得到了同样     

田间大豆光合午休原因的综合研究

本研究利用主成分分析构造同归模型,利用典型相关分析等方法,对自变量的重要程度进行排序,确定了光合午休的主要原因是气孔因素限制所致.光抑光合也是一个值得注意的因素,但不是主要因素.空气相对湿度、叶片与大气间水汽压差是诱发气孔限制的重要因素.当空气相对湿度较为适中时,叶温的影响较小,在空气相对湿度变坏的情况下,叶温才对光合午休有重要影响.
