  nuclear vacuole
In maturing spermatids, silver staining became confined to the fibrils that appeared located inside the nuclear vacuole.
      
The nuclear vacuole also contained a dense fibrillar structure in intimate relationship with these fibrils and the peripheral condensed chromatin.
      
Five different types of nuclear bodies, and besides, a nuclear vacuole, have been observed in type A spermatogonia.
      
On the other hand, the nuclear vacuole lacks a limiting membrane and appears empty.
      
The nucleus of the mature sperm contains only the space in which they formerly existed, now silver negative, as the so-called 'nuclear vacuole'.

  nuclear blebs
Supernumerary ring chromosomes and nuclear blebs in some low-grade malignant soft tissue tumours: atypical lipomatous tumours an
      
Nuclear blebs and micronuclei, which were observed in each case of ALT, also contained chromosome 12 material; and these structures may represent a topological distribution of ring or giant marker chromosomes in the interphase nuclei.
      
Studies of the ultrastructure of somite cells from 13-14 somite chick embryos have indicated the presence of ribosome-like granules in polysome-like configurations in the perinuclear space within nuclear blebs.
      
The average size of the nuclear blebs is approximately 0.3 by 0.24 microns.
      
Nuclear blebs in oocytes of the fishClarias batrachus

  germinal vesicle
Gαi protein was chiefly localized in the plasma membrane of immature oocytes; 1-methyladenine induced redistribution of the αi protein from the plasma membrane to intracellular structure up to the breakdown of the germinal vesicle.
      
We studied the actin cytoskeleton state in Asterias amurensis oocytes within 30 min after the 1-methyladenine-induced maturation until the germinal vesicle breakdown.
      
The main focus is on processes occurring in the oocyte during the first minutes after the impact of the hormone, before the destruction of the germinal vesicle.
      
Progesterone successfully induced germinal vesicle breakdown (GVBD) in oocytes from females fed a B-supplemented diet (+B) and females administered a traditional diet of beef liver and lung (B adequate).
      
1-methladenine (1-MA) induces starfish oocytes maturation via surface reaction followed by the appearance of a cytoplasmic maturation factor which in turn induces germinal vesicle breakdown (GVBD) to resume meiosis.

The specimens of six cases of NHL were observed by electron-microscopy. The results showed that the lyphoma cells had the general features of malignant cell, i.e. nuclear pleomorphism, predominance of euchromatin, large nucleolus, nucleus bleb(s), pseudo inclusion body (intranuclear cytoplasm), prominent interchromatin granules, etc. There was a cluster of granules resembling virus C in the cytoplasma of one lymphoma cell. Observation of normal human lymph nodes on other six patients was conpared with NHL.

我们用透射电镜观察6例非何杰金氏淋巴瘤。发现NHL细胞都具有肿瘤细胞的一般特征:胞核形态多变,以常染色质为多,均有较大的核仁、核泡和假包涵体。而对照组6例正常淋巴结均无此变化。NHL细胞核内出现染色质周围颗粒与对照组之间无明显区别。NHL核内出现染色质间颗粒的意义较染色质周围颗粒要大,在人的淋巴肉瘤细胞中常可发现这种颗粒,我们亦在6例NHL细胞中均可见到单个较大的染色质间颗粒(直径在300A——400埃之间),与其他作者不同的是:有一例NHL多个细胞核中发现成簇的染色质间颗粒,直径为250埃左右,排列整齐紧密,颗粒之间还有条状染色质隔开,其意义尚不清楚,有待进一步观察。此外,有一例淋巴瘤病人的个别瘤细胞胞浆中,见到一堆似C型病毒样颗粒,这提示淋巴瘤可能与病毒感染有关。

Ultrastruetural study of transmission electron microscope(TEM)was performed on the leukemic cells in 21 children with leukemia.We observed that all types of leukemic cells have common abnormal changes, such as the presence of nuclear blebs,pseudoinclusions,nucleosomes,disrupted mitochondrias,and each type of leukemia has its special features which enable to differentiate from each other.We also noticed two types of virus—like particles and some unusual manifestations of leukemic cells,e,g.granular acute lymphoblastic...

Ultrastruetural study of transmission electron microscope(TEM)was performed on the leukemic cells in 21 children with leukemia.We observed that all types of leukemic cells have common abnormal changes, such as the presence of nuclear blebs,pseudoinclusions,nucleosomes,disrupted mitochondrias,and each type of leukemia has its special features which enable to differentiate from each other.We also noticed two types of virus—like particles and some unusual manifestations of leukemic cells,e,g.granular acute lymphoblastic leukemia and areas of chromatin demarcated from the rest of the nucleus(separations)in acute lymphoblas- tic leukemia.The ultrastructural diagnostic significance in differentiating several kinds of leukemic cells was preliminarily discussed.

本文应用透射电镜(TEM)对21例各种类型白血病患儿的白血病细胞的超微结构进行了观察,发现各型白血病细胞具有共同的超微结构的异常变化,如均出现核泡、核内假包涵体、核内小体及线粒体的结构破坏等,亦观察到可作为各类型白血病鉴别特征的各自特殊的形态表现,并见到两种不同结构的病毒样颗粒及一些白血病细胞的少见表现,如颗粒型急淋及急淋白血病细胞中的包绕核染色质的核泡(Sep-aration)。初步探讨了用透射电镜观察白血病细胞的意义。

Mouse oocytes at the germinal vesicle stage without cumulus cells were frozen at-196℃. Ethylene glycol was used as cryoprotectant. Oocytes were cooled at 1℃ per min from room temperature to -5℃ where thin plastic tubings were seeded and held for 10 min. The oocytes were then cooled at 0.3℃ per min to-40℃ and plunged directly into liquid nitrogen. Plastic tubings containing oocytes were thawed in a 37℃ water both for 10 min and ethylene glycol was removed with PBS. Oocytes were washed two timesand placed in TALP...

Mouse oocytes at the germinal vesicle stage without cumulus cells were frozen at-196℃. Ethylene glycol was used as cryoprotectant. Oocytes were cooled at 1℃ per min from room temperature to -5℃ where thin plastic tubings were seeded and held for 10 min. The oocytes were then cooled at 0.3℃ per min to-40℃ and plunged directly into liquid nitrogen. Plastic tubings containing oocytes were thawed in a 37℃ water both for 10 min and ethylene glycol was removed with PBS. Oocytes were washed two timesand placed in TALP medium supplemented with 20% fetal bovine serum. The proportion of the oocytes exhibiting primary polar body formation in vitro and the IVE rate were 43.2% and 25.4% for the frozen-thawed oocytes and 48.6% and 26.4% for the nonfrozen control, respectively. Of 318 frozen-thawel oocytes that were fertilized in vitro, 55(17.3%) developed to 2-cell stage embryos.

试验比较四种防冻剂对小鼠核泡期(germinal vesicle stage)无卵丘细胞的卵母细胞(下称裸卵),在各种不同条件下冷冻-解冻的影响,并用乙二醇为防冻剂,冷冻-解冻后,形态正常的裸卵1137枚,经体外培养排出第一极体、发育达中期Ⅱ的成熟率为43.2%(491/1137)。用体外获能的小鼠附睾尾精子进行体外受精的受精率为25.4%(31/122)。继续培养进一步发育至2-细胞期的发育率为17.3%(55/318)。对照组(新鲜裸卵)的成熟率为48.6%(158/325),受精率为26.4%(388/144)。两者无显著差异(P<0.05)。
