Three races of silkworm, Bombyx mori L. namely univoltine "Bagdad", bivoitine"J×C" (at high incubating temperature) and nondiapausing multivotine "Vietnam"were used as materials in these studies. The brain was fixed in Susa or Bouin. Afterfixation it was embedded in paraffin wax and sectioned at 5μ. The serial sections werestained with Mallory's triple stain, somewhat modified, and Gomori's chrome alum-hematoxylin philoxine. The former method proved excellent for the purpose of thesestudies. The neurosecretory cells observed in the brain are arranged in four groups, namelymedial, lateral, posterior and sternopleural groups in each half of the brain, in all eightgroups. The two medial groups are close together on each side of the midline on thedorsal and anterior parts of the pars intercerebralis. The two lateral groups are situateddorsally beside the medial groups. The posterior groups are located on the posteriorparts of the pars intercerebralis. The two sternopleural groups which had not been men-tioned by other authors before are located on the ventral and external-lateral parts, nearthe oesophageal commissure of the brain. The medial neursecretory cells of the univoltine race "Bagdad" were classified intofive types, namely A-, B-, C-, D- and E-cell, which could be distinguished by their sizeand staining reactions with Mallory's procedures. A-cell stained purple, measuring38μ to 42μ in major diameter (without containing of the large vacuole), B-cell which isintensely acidophil, stained deep red, measuring 19μ to 24μ, C-cell stained light grayish-blue, measuring 23μ to 29μ, D-cell stained deep-blue, measuring 18μ to 23μ, E-cellstained deep purple, slender in shape, measuring 24μ to 29μ. The number of the neurosecretory cells in the univoltine "Bagdad" is about 36 onthe fourth day of 5th larval stage, about 46 in the beginning of the pupal stage, about 48and 50 on the third day and seventh day of the pupal stage, respectively. The difference between univoltine "Bagdad" and multivoltine "Vietnam" withrespect to the neurosecretory cells of the brain is the absence of the "B-cell" in the parsintercerebralis of the brain in the nondiapausing multivoltine race.

家蚕一化性品种“巴格达”的脑以 Susa液固定,制成5微米的连续切片,用 Mallory三重染色对脑神经分泌细胞进行组织学观察结果,脑神经分泌细胞的分群除过去学者所记载的脑间部中央群及侧群外,还有后群及腹侧群(这是过去所未曾记载过的)。脑间部神经分泌细胞的类型,过去学者认为只有A、B两种细胞,根据我们的初步观察,由于其大小及染色性的不同可分为 A、B、C、D、E五种类型,用 Mallory三重染色(改良法),除染成紫色的大型A细胞及染成深紫红色的B细胞外,还有染成淡蓝灰色的C细胞,染成蓝色的D细胞及染成淡蓝紫色的长型E细胞。无滞育多化性“越南”品种脑间部神经分泌细胞与一化性“巴格达”品种所存在的差异初步观察为“越南”品种脑间部缺乏嗜复红的“B”细胞。

This paper reports the development and changes of. the eggs of Schistosoma japonicum in the tissues of mice and rabbits.The eggs were laid by female worms on the 25-26th day after infection. They took about 9-10 days for their development and the maximum life-span of the eggs was about 21-22 days.Eggs dying naturally or due to the reactions of the host or the actions of certain drugs showed marked changes in their features. Based on the characteristics of the changes, the time of death might be estimated. The most obvious changes were shown to be as follows: the egg shell increased in thickness, the shell surface became coarse, the embryonic membrane was blurred, and the embryo or miracidium became atrophied in the form of a reticulum. But for most of the granular eggs, even long after the time of death, the shell was still very thin, the embryonic membrane was clear, being golden-yellow in color, whereas the internal structure of the eggs was disturbed, the yolk granules became different in size, heterogeneous in refraction and there were spaces among the granules. Generally, the longer the time after the death of the eggs, the more marked the changes; but the rate of the changes was correspondingly slow. When the worms died in the host body, most of the eggs might be absorbed by the host tissues, with only a small number remaining for quite a long time.A fluorescence-staining method was introduced for the determination of dead and living eggs in the host tissues. The living eggs showed an orange-red fluorescence, or red and green fluorescence alternately. After dying, the eggs showed an orange-yellow, then yellow-green fluorescence and eventually turned to blue.

观察了日本血吸虫卵在小白鼠、家兔组织内发育和演变的情况。 自然地死亡的虫卵,或因宿主组织反应以及某些药物作用引起死亡的虫卵。其形态上发生显著的变化,主要表现在卵壳增厚,表面粗糙不平,胚膜不清楚,卵内的胚胎或幼虫萎缩成块状或结构模糊呈网状。但大部分颗粒性虫卵虽死亡已久,其卵壳始终很薄,部分胚膜清楚,色泽金黄,然而卵内的结构紊乱,表现为颗粒大小不一,折光不均匀,有空隙。一般,虫卵死亡时间越长,这种变化越明显。但其变化的速度相当缓慢,宿主体内虫子死亡后,大部分虫卵可以逐渐被组织吸收,还有部分虫卵可在组织内保留相当长的时间。 介绍了一种鉴别组织内虫卵死活的吖啶橙萤光染色法:活虫卵发橙红色或红绿相嵌色彩的萤光,虫卵死亡后,随着时间的延长,虫卵由橙黄色、黄绿色,继之转为发蓝色的萤光。此法虽需仪器设备,但方法敏感,对于科研工作是有价值的。 对某些虫卵的特点,吖啶橙萤光染色法的原理进行了简单的讨论。

Hyoscyamine and scopolamine are contained in the callus induced from the root, stem and leaf of seedling of Anisodus acutangulus as well as in the callus induced from the anther and seed coat. Stem-callus and leaf, callus possesed the highest content of hyoscyamine and scopolamine and the highest growth rate.

从三分三种子萌发的根、茎、叶和花药、种皮诱导的愈伤组织,均含有莨菪碱、东莨菪碱。其含量和生长速度均以茎、叶愈伤组织为最高。根、茎、叶愈伤组织,在培养基中分别加入各种植物激素,培养时表明:BA(6-苄基嘌呤)促进芽的分化,NAA促进根的分化,2,4-D则抑制根的分化,GA_3(赤霉酸)影响很小。获得了三种愈伤组织只分化根不分化芽(加NAA 1毫克/升)和只分化芽不分化根(每升中加BA0.2毫克和2,4-D 0.2毫克)的良好结果。分化的这些芽或根的诱导频率,以茎、叶愈伤组织为高。分化的芽或根中均含有莨菪碱及东莨菪碱,但其含量相应地比它们的未分化的愈伤组织约低1~4倍。薄层层析结果表明,愈伤组织中有6种生物碱,茎、叶愈伤组织中,还有一种在紫外光下显蓝色荧光的物质,而分化的根或芽及花药愈伤组织中只有4种生物碱。看来,在离体培养下的三分三愈伤组织是有莨菪碱和东莨菪碱合成的全能性。这两种生物碱似乎并非最终的代谢产物,它们可能参与了器官建成中的代谢过程。文中还讨论了莨菪碱和东莨菪碱的合成部位问题。
