In addition, the role of the RER in protein body forming, the role of amyloplast envelope in amyloplast proliferating, the relations between nucleus and cytoplasm of starchy endosperm cells in rice, and the variation of nucleus in plant PCD, the roles of plasmalemma invagination, ER, Ca〓 and phosphatases during endosperm development were discussed.

本文对粗面内质网在蛋白体形成中的作用，淀粉质体被膜在淀粉质体增殖中的作用，淀粉胚乳细胞的核质关系，植物PCD中细胞核的变化，以及质膜内陷、内质网、Ca〓和磷酸水解酶在胚乳发育中的作用等进行了讨论。

These results suggested that many organella could all develop into amyloplast, variation of amyloplast envelope resulted in amylopast proliferation, RER played an important role in synthesis and deposition of protein, ER showed many functions during endosperm development, intercellular space and plasmalemma invagination played an important role in transportation of nutrients, degeneration of starchy endosperm nucleus was a special PCD, Ca〓 and phosphatases played an important role during endosperm development.

上述结果表明：多种细胞器可以趋同发育成淀粉质体，淀粉质体增殖来源于其被膜的活动，粗面内质网在蛋白质的合成与积累中具有重要作用，内质网在胚乳发育中具有多种功能，胞间隙和质膜内陷在营养物质的运输中具有重要作用，淀粉胚乳细胞核的衰退是一种特殊形式的编程性死亡，Ca〓和磷酸水解酶在胚乳发育中起重要作用。

Results There were fetal type in 12 cases, embryonal type in 7 cases, anaplasia type in 3 and mixed type in 2. The cytoplasmic postive expression of CK, AFP, S-100 protein and Vimentin of epithelial tumor cells were found in 14, 10, 9 and 6 cases respectively. Positive staining of CEA, P53 and P16 of nuclei of epithelial tumor cells were found in 11, 9 and 7 cases respectively.Among the 12 cases who underwent surgical excision, 8 patients with fetal type survived over 5 years. Conclusions This study suggests that immunoreaction of hepatoblastomas are different in the histological subtypes.

结果 胎儿型12例，胚胎型7例，间变型3例和上皮间叶混合型2例；细胞角蛋白、甲胎蛋白、S-100蛋白和波形蛋白在肿瘤上皮细胞浆的表达分别为14例、10例、9例和6例，癌胚抗原、P53和P16蛋白在细胞核中的表达分别是11例、9例和7例；手术切除肿瘤12例中8例生存期超过5年者均为胎儿型。

Wilms tumors with unfaorable histology contain anaplasia – defined as the presence of hyperchromatic, enlarged nuclei (at least 3 times as large as blastemal nuclei), and multipolar mitotic figures.

如有细胞间变则提示Wilms'瘤预后不良，所谓细胞间变，表现为染色质粗糙，胞核增大（至少是后肾胚芽细胞核的3倍大小）以及多极性有丝分裂像。

The number of theromosomes per nucleus is characteristic of the species except in aneuploid plants.

除了少数非整倍性的植物，细胞核内染色体的数目是物种的重要特征。

The database, which contains DNA C-values for just over 1 % of known angiosperm species, represents the largest database of nuclear DNA amounts available for any group of organisms.

该数据库，其中含有的DNA的C -值刚刚超过1 ％已知被子植物物种，代表了最大的数据库的细胞核DNA的金额可供任何一组的有机体。

Animal pole: The portion of an egg opposite the vegetal pole that contains the nucleus and most of the cytoplasm.

动物性极：与包含细胞核和多数细胞质的植物性极相对的卵的部分。
