The cancer cells are in different differentiation periods: the chromatin of the young cancer cell's nucleus is rich in color and its cytoplasm is basophilous. The young cancer cells don't form into typical glandular cavity; The mature cancer cell is columnar or cubical and its nucleus is located at the base of the cell in gland tube-like arrangement; The decrepit cancer cell stain thin while its nucleus stain dense. The severer's nucleus disintegrate into small fragments. The decrepit cancer cell's arrangement is disorganized, only keeping its glandular shape.

显微镜下癌细胞呈现不同的分化程度：幼稚型癌细胞胞核染色质丰富，胞质嗜碱性，不形成典型腺腔；成熟型癌细胞呈柱状或立方状，细胞核位于细胞基部，呈腺管样排列；衰老型癌细胞胞桨染色变淡，胞核浓染，严重者胞核碎裂成细小碎片，衰老型癌细胞排列紊乱，仅保留腺体样结构轮廓。

But,the natural pollen is what the person's stomach can't absorb and the natural nucleic acid also can't be absorbed as apoenzyme constituting the cell nucleus or mass.Therefore swallowing "natural pollen" is a kind of waste.

但是，天然花粉是人的胃不能吸收的，花粉中的天然核酸胃也是不能(如脱辅基酶，一种除去辅基的酶蛋白，或统称氨基酸一样地)被吸收的。

Results During the committed differentiation, the expression of calmodulin was distributed in and around the cell nucleus.

结果在神经干细胞定向分化为神经元的过程中，钙调蛋白于细胞核及核周呈阳性表达，随分化神经元的生长细胞核阳性表达逐渐减弱而胞浆增强，同时可见阳性反应物伸入树突及轴突。

Methods The changes of contents of AGEs in plasma and the abdominal aorta and changes of VSMC of the abdominal aorta were investigated with methods of fluorospectrophotometry, immunohistochemistry, computer image analysis and transmission electron microscopy on streptozotocin-induced diabetic rats. Results From the fourth week, in diabetic rats, the contents of AGEs in plasma and the abdominal aorta increased, the relative area of α-SM-actin in the abdominal aorta decreased, the density of nucleus of VSMC increased, and mitochondria and rough endoplasmic reticules in VSMC increased.

后者在早期主要是血管平滑肌细胞(vascular smooth muscle cell， VSMC)和胶原纤维增多，弹性纤维减少，动脉增厚等，引起动脉的顺应性降低，舒张功能减弱［1～3］；晚期主要表现为动脉粥样硬化和动脉硬化，其中以VSMC的增生和迁移较为突出，其表型也由收缩型转化为合成型［4，5］。
